Patients suffering from adult lumbar degenerative scoliosis (ALDS) are commonly complicated with advanced age, osteoporosis, cardiopulmonary insufficiency, and some other medical comorbidity. Therefore, the traditional open surgery can lead to high rate of postoperative complications. The purposes of this study were to introduce our experiences and explore the efficacy and feasibility of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of patients with ALDS. From January 2008 to January 2014, a retrospective study of 22 patients with ALDS treated with MIS-TLIF was followed up at least 2 years. All patients suffered from one-level lumbar stenosis, and the nerve root block was performed to make sure the exact level. The clinical and radiographic outcomes were evaluated preoperatively and at the time of 2-year follow-up. The mean visual analog scale (VAS) back pain scores decreased from 6.2 ± 1.8 preoperatively to 2.2 ± 0.7 at 2-year follow-up (P < 0.05), and the mean VAS leg pain scores decreased from 8.2 ± 0.7 preoperatively to 1.4 ± 1.4 at 2-year follow-up (P < 0.05). The Oswestry Disability Index score improved from 62.4 ± 16.1% preoperatively to 24.2 ± 9.3% at 2-year follow-up (P < 0.05). The average lumbar curve was 20.7° ± 7.0° preoperatively and 12.7° ± 7.1° at 2-year follow-up (P < 0.05). The lumbar lordosis changed from - 39.5° ± 13.6° to - 43.6° ± 10.6° at 2-year follow-up (P < 0.05). Solid fusion was achieved in all patients. The technique of MIS-TLIF can be used to treat the patients with ALDS whose symptom is mainly from one-level lumbar stenosis, achieving favorable clinical outcomes and good fusion, with less blood loss and complications.

New noninvasive techniques as well as conventional methods were used to evaluate skeletal mass in the following three populations of adult white women as follows: (1) 79 subjects with preexisting idiopathic scoliosis designated as unstable (US) because of the associated presence in the lumbar spine of lateral spondylolisthesis with segmental instability; (2) 67 subjects with preexisting idiopathic scoliosis without lateral spondylolisthesis designated as stable (SS); and (3) 248 age-matched nonscoliotic controls. Ages in all three groups were categorized into premenopausal (25-44 years), perimenopausal (45-54 years), and postmenopausal (55-84 years). The results showed higher scoliosis morbidity in the US compared tomore » the SS populations. The prevalence and severity of osteoporosis were markedly increased in US versus SS populations. Femoral neck density determined by dual-photon absorptiometry techniques averaged 26% to 48% lower in all age categories of US patients compared to controls. These changes were found in the youngest age groups, indicating reductions in bone mineral content earlier in the adult life of white women with a specific type of high-morbidity US characterized by the marker of lateral spondylolisthesis.« less

Scoliosis is a complex three-dimensional (3D) spinal deformity. Acquired scoliosis in early childhood may progress into adulthood and pose an increased risk of health problems and reduction in quality of life. In Canada, patients with scoliosis are not referred for physiotherapeutic scoliosis-specific exercises (PSSE) despite the fact that Schroth physiotherapy, a scoliosis-specific 3D posture training and exercise program, can be effective in reducing pain and improving scoliosis curves, vital capacity, and overall quality of life in scoliosis patients. This case presentation shows that indeed adult curve progression can be stopped and even reversed with scoliosis specific Schroth physiotherapy (SSSPT) in an adult patient with scoliosis. This is a retrospective case presentation involving a 23-year-old female scoliosis patient who began an outpatient Schroth physiotherapy exercise program and was initially monitored monthly and then annually for improvement in measurements of angle of trunk rotation (ATR) and chest expansion and improvement in vital capacity measured with incentive spirometry. Photos were taken to document body image periodically throughout Schroth physiotherapy treatment. Additionally, the patient completed SRS-22 quality of life questionnaires every 2 years to evaluate daily function, pain, self-imagine, mental health, and scoliosis management satisfaction. Within one month of beginning SSSPT, the patient reported no more back pain and within 2 months, reported improved breathing. The patient also benefitted from improved chest expansion, reduced scoliosis curve angles (measured in Cobb degrees), increased vital capacity, decreased ATR, and higher SRS-22 scores. She became more active and resumed all athletic activity within 8 months of beginning Schroth physiotherapy. Adult scoliosis patients are not routinely referred for PSSE in Canada, even though Schroth physiotherapy, a form of PSSE, is shown to be effective in this case presentation

Several methods are used to measure lumbar lordosis. In adult scoliosis patients, the measurement is difficult due to degenerative changes in the vertebral endplate as well as the coronal and sagittal deformity. We did the observational study with three examiners to determine the reliability of six methods for measuring the global lumbar lordosis in adult scoliosis patients. Ninety lateral lumbar radiographs were collected for the study. The radiographs were divided into normal (Cobb < 10°), low-grade (Cobb 10°–19°), high-grade (Cobb  ≥ 20°) group to determine the reliability of Cobb L1–S1, Cobb L1–L5, centroid, posterior tangent L1–S1, posterior tangent L1–L5 and TRALL method in adult scoliosis. The 90 lateral radiographs were measured twice by each of the three examiners using the six measurement methods. The data was analyzed to determine the inter- and intra-observer reliability. In general, for the six radiographic methods, the inter- and intra-class correlation coefficients (ICCs) were all ≥0.82. A comparison of the ICCs and 95% CI for the inter- and intra-observer reliability between the groups with varying degrees of scoliosis showed that, the reliability of the lordosis measurement decreased with increasing severity of scoliosis. In Cobb L1–S1, centroid and posterior tangent L1–S1 methods, the ICCs were relatively lower in the high-grade scoliosis group (≥0.60). And, the mean absolute difference (MAD) in these methods was high in the high-grade scoliosis group (≤7.17°). However, in the Cobb L1–L5 and posterior tangent L1–L5 method, the ICCs were ≥0.86 in all groups. And, in the TRALL method, the ICCs were ≥0.76 in all groups. In addition, in the Cobb L1–L5 and posterior tangent L1–L5 method, the MAD was ≤3.63°. And, in the TRALL method, the MAD was ≤3.84° in all groups. We concluded that the Cobb L1–L5 and the posterior tangent L1–L5 methods are reliable methods for measuring the global lumbar lordosis

Schwab classification for adult degenerative scoliosis (ADS) concluded that health-related quality of life was closely related to curve type and three sagittal modifiers. It was suggested that pelvic incidence minus lumbar lordosis value (PI-LL) should be corrected within -10°~+10°. However, recent studies also indicated that ideal clinical outcomes could also be achieved in patients without the ideal PI-LL mentioned above. This study evaluated the relation between the clinical outcomes and the PI-LL of Chinese patients with ADS who received long posterior internal fixation and fusion. This was a single-center retrospective comparative study of patients treated by long posterior internal fixation and fusion in our hospital between 2010 and 2014. Inclusion criteria were age >45 years at the time of surgery, Cobb angle of lumbar curves ≥10°, long posterior internal fixation and fusion ≥least 3 motion segments, follow-up ≥2 years, complete preoperative and postoperative radiographic data, and functional evaluation results. Exclusion criteria were history of previous lumbar spine surgery, other kinds of scoliosis, history of severe spinal trauma, spinal tumor, ankylosing spondylitis, and spinal tuberculosis. Seventy-four patients were enrolled in this study. Operative parameters included intraoperative blood loss, duration of surgery, length of hospital stay, number of fusion levels, and decompression. The radiological measurements included Cobb angle of the curves and PI-LL. Clinical outcomes were evaluated by the Japanese Orthopaedic Association score, Oswestry Disability Index (ODI), visual analog scale, and Lumbar Stiffness Disability Index (LSDI). In addition, the complications of surgery were also collected. One-way analysis of variance, Student t test, Kruskal-Wallis test, Pearson chi-square test, and curve estimation were calculated for variables. All the patients were divided into Group 1 (long instrumentation and fusion to L5) and Group 2 (long

A prospective cohort of adult scoliosis patients treated nonoperatively had a minimum of 2-year follow-up during which time data were collected on the type and quantity of nonoperative treatment used. To quantify the use, cost, and effectiveness of nonoperative treatment for adult scoliosis. A 2007 systematic review of nonsurgical treatment in adult scoliosis revealed minimal data, and concluded that evidence for nonoperative care was lacking. Duration of use and frequency of visits were collected for 8 specific treatment methods: medication, physical therapy, exercise, injections/blocks, chiropractic care, pain management, bracing, and bed rest. Costs for each intervention were determined using the Medicare Fee schedule. Outcome measures were the SRS-22, SF-12, and ODI. Analysis was performed for the entire group, and for subsets of high (ODI, >40), mid (ODI = 21-40) and low (ODI, scoliosis patients who received no treatment, the only significant change in HRQOL measures over the 2-year period was in SRS satisfaction subscore (0.3 points, P = 0.014). Among the 68 adult scoliosis patients who used nonoperative resources, there was no significant change in any of the HRQOL outcome parameters. Mean treatment cost over the 2-year period was $10,815. Mean cost over the 2-year period averaged $9704 in the low symptom patients, $11,116 in the mid symptom, and $14,022 in the high symptom patients. This study questions the value of nonoperative treatment commonly used for adult scoliosis patients. Documented costs are substantial and no improvement in health status was observed. An important caveat is that treatment was not randomized and therefore the treatment group might have deteriorated if not for the treatment they received.

This study aims at verifying if impaired sensorimotor control observed in adolescents and young adults with scoliosis is also present in adult patients who underwent surgery to reduce their spine deformation. The study included ten healthy adults and ten adults with idiopathic scoliosis who underwent surgery to reduce their spine deformation. Galvanic vestibular stimulation was delivered to assess sensorimotor control. Vertical forces under each foot and horizontal displacement of the upper body were measured before, during and after stimulation. Balance control was assessed by calculating the root mean square values of kinematic and kinetic variables. The amplitude of the vestibular-evoked postural response was 3.4 % (0.8-6.0 %) and 4.5 % (-0.4 to 9.5 %) of the maximal range of motion. Therefore, spine surgery did not limit the postural response. Patients with idiopathic scoliosis exhibited larger body sway than the healthy controls during and immediately after vestibular stimulation. The maximal normalized lateral displacement of the body was 0.85 and 0.40 cm/m and maximal normalized vertical force was 0.78 vs. 0.39 N/kg, for idiopathic scoliosis and healthy groups, respectively. This result suggests that dysfunctional sensorimotor integration is still present even in adult idiopathic scoliosis that underwent spine deformation correction.

Outcomes for minimally invasive scoliosis correction surgery have been reported for mild adult scoliosis. Larger curves historically have been treated with open surgical procedures including facet resections or posterior column osteotomies, which have been associated with high-volume blood loss. Further, minimally invasive techniques have been largely reported in the setting of degenerative scoliosis. We describe the effects of circumferential minimally invasive surgery (cMIS) for moderate to severe scoliosis in terms of (1) operative time and blood loss, (2) overall health and disease-specific patient-reported outcomes, (3) deformity correction and fusion rate, and (4) frequency and types of complications. Between January 2007 and January 2012, we performed 50 cMIS adult idiopathic scoliosis corrections in patients with a Cobb angle of greater than 30° but less than 75° who did not have prior thoracolumbar fusion surgery; this series represented all patients we treated surgically during that time meeting those indications. Our general indications for this approach during that period were increasing back pain unresponsive to nonoperative therapy with cosmetic and radiographic worsening of curves. Surgical times and estimated blood loss were recorded. Functional clinical outcomes including VAS pain score, Oswestry Disability Index (ODI), and SF-36 were recorded preoperatively and postoperatively. Patients' deformity correction was assessed on pre- and postoperative 36-inch (91-cm) standing films and fusion was assessed on CT scan. Minimum followup was 24 months (mean, 48 months; range, 24-77 months). Mean blood loss was 613 mL for one-stage surgery and 763 mL for two-stage surgery. Mean operative time was 351 minutes for one-stage surgery and 482 minutes for two-stage surgery. At last followup, mean VAS and ODI scores decreased from 5.7 and 44 preoperatively to 2.9 and 22 (p < 0.001 and 0.03, respectively) and mean SF-36 score increased from 48 preoperatively to

To evaluate the influence of Scoliosis Research Society (SRS)-Schwab sagittal modifiers of pelvic incidence minus lumbar lordosis mismatch (PI-LL) on clinical outcomes for adult degenerative scoliosis (ADS) after long posterior instrumentation and fusion. This was a single-institute, retrospective study. From 2012 to 2014, 44 patients with ADS who underwent posterior instrumentation and fusion treatment were reviewed. Radiological evaluations were investigated by standing whole spine (posteroanterior and lateral views) X-ray and all radiological measurements, including Cobb's angle, LL, PI, and the grading of vertebral rotation, were performed by two experienced surgeons who were blind to the operations. The patients were divided into three groups based on postoperative PI-LL and the classification of the SRS-Schwab: 0 grade PI-LL (<10°, n = 13); + grade PI-LL (10°-20°, n = 19); and ++ grade PI-LL (>20°, n = 12). The clinical outcomes were assessed according to Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index (ODI), Visual Analog Scale (VAS), Lumbar Stiffness Disability Index (LSDI), and complications. Other characteristic data of patients were also collected, including intraoperative blood loss, operative time, length of hospital stay, complications, number of fusion levels, and number of decompressions. The mean operative time, blood loss, and hospital stay were 284.5 ± 30.2 min, 1040.5 ± 1207.6 mL, and 14.5 ± 1.9 day. At the last follow-up (2.6 ± 0.6 years), the radiological and functional parameters, except the grading of vertebral rotation, were all significantly improved in comparison with preoperative results (P < 0.05), but it was obvious that an ideal PI-LL (≤10°) was not achieved in some patients. Significant differences were only observed among the three groups in the ODI and LSDI. Patients with + grade PI-LL seemed to have the best surgical outcome compared to those with 0 and

Cross-sectional. To describe physical activity level and fracture rates in adults with idiopathic scoliosis, diagnosed before maturity, and to compare with a control group. A previous study found a lower level of sporting activities in adults treated for idiopathic scoliosis compared with controls. Other studies have shown a lower bone mass in adults with idiopathic scoliosis compared with controls. One thousand two hundred seventy-eight adults (aged 18-71 yr) with idiopathic scoliosis and 214 controls (aged 18-70 yr) were included and answered the International Physical Activity Questionnaire - Short Form (IPAQ-SF) and questions about previous fractures. The three scoliosis treatment groups (untreated n = 360, brace n = 460, and surgically treated n = 458) were compared. Furthermore, a comparison based on onset (juvenile n = 169 or adolescent n = 976) was performed. Achieved weekly moderate activity level and metabolic equivalent task (MET) minutes/week were assessed for patients and controls. Statistical comparisons were made with analysis of covariance with adjustments for age, body mass index, and sex. The proportion achieving weekly moderate activity level was 962 out of 1278 for individuals with idiopathic scoliosis (75%) and 157 out of 214 (73%) for controls (P = 0.40). The scoliosis patients reported 2016 MET-minutes/week (median value) and the controls 2456 (P = 0.06). Fracture rates did not differ (P = 0.72). Fewer surgically treated individuals achieved moderate activity level (P = 0.046) compared with the untreated and the previously braced individuals. No difference was seen regarding MET-minutes/week (P = 0.86). No differences were seen between individuals with a juvenile onset compared with individuals with an adolescent onset (all P ≥ 0.05). Adults with idiopathic scoliosis have similar physical activity level and do not sustain more fractures compared with controls. Adults with surgically treated

This study evaluates baseline patient characteristics and surgical parameters for risk factors of medical complications in ASD patients received posterior long level internal fixation. Analysis of consecutive patients who underwent posterior long-level instruction fixation for adult degenerative scoliosis (ADS) with a minimum of two year follow-up was performed. Pre-operative risk factors, intraoperative variables, peri-operative radiographic parameters, and surgical-related risk factors were collected to analyze the effect of risk factors on medical complications. Patients were separated into groups with and without medical complication. Then, complication group was further classified as major or minor medical complications. Potential risk factors were identified by univariate testing. Multivariate logistic regression was used to evaluate independent predictors of medical complications. One hundred and thirty-one ADS patients who underwent posterior long segment pedicle screws fixation were included. Total medical complication incidence was 25.2%, which included infection (12.2%), neurological (11.5%), cardiopulmonary (7.6%), gastrointestinal (6.1%), and renal (1.5%) complications. Overall, 7.6% of patients developed major medical complications, and 17.6% of patients developed minor medical complications. The radiographic parameters of pre-operative and last follow-up had no significant difference between the groups of medical complications and the major or minor medical complications subgroups. However, the incidence of cerebrospinal fluid leak (CFL) in patients who without medical complications was much lower than that with medical complications (18.4 vs. 42.4%, P = 0.005). Independent risk factors for development of medical complications included smoking (OR = 6.45, P = 0.012), heart disease (OR = 10.07, P = 0.012), fusion level (OR = 2.12, P = 0.001), and length of hospital stay (LOS) (OR = 2.11, P = 0.000).

Objective. To examine general mental health in adult males and females, who in adolescence participated in a scoliosis-specific therapeutic exercise program or were under observation due to diagnosis of scoliosis. Design. Registry-based, cross-sectional study with retrospective data collection. Methods. Sixty-eight subjects (43 women) aged 30.10 (25–39) years, with mild or moderate scoliosis (11–36° Cobb angle), and 76 (38 women) nonscoliotic subjects, aged 30.11 (24–38) years, participated. The time period since the end of the exercise or observation regimes was 16.5 (12-26) years. Beck Depression Inventory (BDI) and General Health Questionnaire (GHQ-28) scores were analyzed with the χ 2 and U tests. Multiple regression analyses for confounders were also performed. Results. Intergroup differences of demographic characteristics were nonsignificant. Scoliosis, gender, participation in the exercise program, employment, and marital status were associated with BDI scores. The presence of scoliosis and participation in the exercise program manifested association with the symptoms. Higher GHQ-28 “somatic symptoms” subscale scores interacted with the education level. Conclusions. Our findings correspond to the reports of a negative impact of the diagnosis of scoliosis and treatment on mental health. The decision to introduce a therapeutic program in children with mild deformities should be made with judgment of potential benefits, risks, and harm. PMID:24574935

Scoliosis fusion surgery is generally considered the only means to stop the progression of adult idiopathic scoliosis (ADIS), but for patients refusing surgery there is lack of evidence in favour of conservative treatment. The aim of the present study was to verify the possible effectiveness of scoliosis-specific exercises when facing ADIS progression. We designed a retrospective cohort study. We included 34 ADIS patients in treatment at our Institute (5 males and 29 females, mean age was 38.0 ± 11.0), exclusively treated with specific Scoliosis Specific SEAS exercises. SEAS exercises are scoliosis-specific exercises. In adult patients they are aimed to recover postural collapse, postural control and vertebral stability through an active self-correction. Postural integration is a key element, including the neuromotor integration of correct postures and an ergonomic education program. Therapy includes at least two weekly exercise sessions each lasting 45 min. Radiographic progression was the main outcome and it was analysed as a continuous variable. One way ANOVA and paired t-test were applied for continuous data, while chi-square test was applied for categorical data. Alpha was set at 0.05. The mean Cobb angle of the patients included into the present study, was 55.8 ± 13.2 °. Fifteen patients had previous x-rays testifying scoliosis progression: the average curve progression (worsening) was 9.8 ± 6.6 ° at a median of 25 (range 17-48) years. The remaining were characterized by more severe curves, exceeding 40 ° Cobb (mean curvature 50.9 ± 13.6) but it was not possible to prove that the curves had progressed in these cases. After an average period of 2 years of treatment (range 1-18y), 68 % of the patients experienced an improvement in their scoliosis. However in one patient (3 %) the scoliosis worsened by 5 ° in 18 years (progression rate reduced from 0.5 ° to 0.27 ° per year). Patients improved 4.6 ± 5.0 ° Cobb

Objective: To evaluate the influence of PI-LL (pelvic incidence minus lumbar lordosis mismatch) on scoliosis correction, living quality and internal fixation related complications for adult degenerative scoliosis (ASD) after long posterior instrumentation and fusion. Methods: A total of 79 patients with ADS underwent long posterior instrumentation and fusion in the Department of Orthopedics at Beijing Chao Yang Hospital from January 2010 to January 2014 were retrospectively reviewed.There were 21 males and 58 females aging from 55 to 72 years with the mean age (63.4±4.8)years. The patients were divided into three groups according to immediately postoperative PI-LL: PI-LL<10°, 10°≤PI-LL≤20°, PI-LL>20°.Compare the Cobb's angles, PI-LL, Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index (ODI), Visual Analog Scale (VAS) and Lumbar Stiffness Disability Index (LSDI). Measurement data were compared via t test and ANOVA, enumeration data were compared via Kruskal-Wallis test, noncontiguous data was performed by χ(2) test. Univariate linear regression equation was performed to investigate the relative influences of postoperative PI-LL on postoperative radiographic parameters and clinical outcome. Results: All the operations were successful without intraoperative complications. The operation time was 145-310 minutes (235.3±42.0) minutes, the intraoperative blood loss was 300-5 300 ml (1 021±787) ml, the duration of hospital was 12-18 d (14.5±1.3) d. A total of 4 to 10 (7.0±1.1) vertebra levels were fused. Compared to preoperative, the Cobb's angle of scoliosis ((4.2±1.8)° vs . (20.1±2.7)°), PI-LL ((16.1±8.6)° vs .

Scoliosis, a permanent abnormal curvature of the spine to the side, is divided into four forms: idiopathic (infantile, juvenile and adolescent, accounting for 80% of cases), neurogenic, congenital and adult scoliosis. Most patients with adolescent idiopathic scoliosis initially have mainly cosmetic problems. However, neurogenic, congenital and adult scoliosis can lead to severe clinical symptoms. The leading symptom is back pain caused by secondary changes. In recent years the Lenke classification has been proven to be a reliable tool for disease classification. Non-progressive scoliosis is usually treated conservatively. In the case of Cobb angles of greater than 50°, surgical therapy is recommended in patients presenting before adulthood. Technical improvements in implants and the optimisation of surgical methods have set a trend in the direction of surgical therapy.

Ambispective cohort review. To examine the effects of early mobilization on patient outcomes, complications profile, and 30-day readmission rates. Prolonged immobilization after surgery can result in functional decline and an increased risk of hospital-associated complications. We conducted an ambispective study of 125 elderly patients (>65 years) undergoing elective spinal surgery for correction of adult degenerative scoliosis. We identified all unplanned readmissions within 30 days of discharge. Unplanned readmissions were defined to have occurred as a result of either a surgical or a nonsurgical complication. "Days of immobility" was defined as the number of days until a patient moved out of bed beyond a chair. Patients in the top and bottom quartiles were dichotomized into "early ambulators" and "late ambulators", respectively. Early ambulators were ambulatory within 24 hours of surgery, whereas late ambulators were ambulatory at a minimum of 48 hours after surgery. Complication rates, duration of hospital stay, and 30-day readmission rates were compared between early ambulators and late ambulators. Baseline characteristics were similar between both cohorts. Compared with patients with a longer duration of immobility (i.e., late ambulators), the prevalence of at least one perioperative complication was significantly lower in the early ambulators cohort (30% vs. 54%, P = 0.06). The length of inhospital stay was 34% shorter in the early ambulators cohort (5.33 days vs. 8.11 days, P = 0.01). Functional independence was superior in the early ambulators cohort, with the majority of patients discharged directly home after surgery compared with late ambulators (71.2% vs. 22.0%, P = 0.01). Early ambulation after surgery significantly reduces the incidence of perioperative complications, shortens duration of inhospital stay, and contributes to improved perioperative functional status in elderly patients. Even a delay of 24 hours to ambulation is

The impact of patient self assessment of deformity on HRQL in adults with scoliosis

Background Body image and HRQL are significant issues for patients with scoliosis due to cosmetic deformity, physical and psychological symptoms, and treatment factors. A selective review of scoliosis literature revealed that self report measures of body image and HRQL share unreliable correlations with radiographic measures and clinician recommendations for surgery. However, current body image and HRQL measures do not indicate which aspects of scoliosis deformity are the most distressing for patients. The WRVAS is an instrument designed to evaluate patient self assessment of deformity, and may show some promise in identifying aspects of deformity most troubling to patients. Previous research on adolescents with scoliosis supports the use of the WRVAS as a clinical tool, as the instrument shares strong correlations with radiographic measures and quality of life instruments. There has been limited use of this instrument on adult populations. Methods The WRVAS and the SF-36v2, a HRQL measure, were administered to 71 adults with scoliosis, along with a form to report age and gender. Preliminary validation analyses were performed on the WRVAS (floor and ceiling effects, internal consistency and collinearity, correlations with the SF-36v2, and multiple regression with the WRVAS total score as the predictor, and SF-36v2 scores as outcomes). Results The psychometric properties of the WRVAS were acceptable. Older participants perceived their deformities as more severe than younger participants. More severe deformities were associated with lower scores on the Physical Component Summary Score of the SF-36v2. Total WRVAS score also predicted Physical Component Summary scores. Conclusion The results of the current study indicate that the WRVAS is a reliable tool to use with adult patients, and that patient self assessment of deformity shared a relationship with physical rather than psychological aspects of HRQL. The current and previous studies concur that revision of the

Lumbar scoliosis affects patients' quality of life and will increasingly burden the health-care system as the population ages, yet there have been few reports of its prevalence in Asians. The aim of this study was to identify the prevalence of scoliosis, curve characteristics, and risk factors for development of scoliosis in an Asian population. A retrospective cross-sectional study was conducted using spinal images obtained from dual x-ray absorptiometry (DXA) scans of individuals ≥40 years of age. Scoliosis was defined as a curvature of >10°. A multivariate analysis for risk factors for development of lumbar scoliosis was performed. Of 7,075 patients studied, 645 (9.1%) were identified as having scoliosis. The average age of the patients with scoliosis was 61 years (range, 40 to 98 years). The mean curve prevalence was 9.4% in women and 6.5% in men. The average Cobb angle was 16.5° (range, 10° to 66°). Multivariate analysis showed an increased risk of scoliosis in women (relative risk [RR] = 2.4, 95% CI =1.4 to 4.3), Chinese patients (RR = 2.4, 95% CI = 1.4 to 4.3), Malay patients (RR = 2.5, 95% CI = 1.3 to 4.9), and patients with spinal fracture (RR = 5.1, 95% CI = 3.0 to 8.8). The risk of scoliosis was found to increase as patients progressed through each decade of life after the age of 40 years (6th decade: RR = 1.6, 95% CI = 1.1 to 2.4, p = 0.026; 7th decade: RR = 2.7, 95% CI = 1.8 to 4.1, p < 0.001; 8th decade: RR = 5.0, 95% CI = 3.2 to 7.9, p < 0.001; and 9th decade: RR = 8.8, 95% CI = 4.3 to 17.9, p < 0.001). The prevalence of lumbar scoliosis in Asian adults was found to be 9.1%. A nearly exponential increase in scoliosis prevalence from the 5th decade of life (4%) to the ≥9th decade (25%) and a majority of left-sided scoliotic curves, measuring between 10° and 19° with an L2 apex, was found. Older age, female sex, Chinese or Malay race, and vertebral fracture increased the risk of scoliosis developing. Prognostic Level IV. See Instructions for

Sagittal malalignment is frequently observed in adult scoliosis. C7 plumb line, lumbar lordosis and pelvic tilt are the main factors to evaluate sagittal balance and the need of a vertebral osteotomy to correct it. We described a ratio: the lumbar lordosis index (ratio lumbar lordosis/pelvic incidence) (LLI) and analyzed its relationships with spinal malalignment and vertebral osteotomies. 53 consecutive patients with a surgical adult scoliosis had preoperative and postoperative full spine EOS radiographies to measure spino-pelvic parameters and LLI. The lack of lordosis was calculated after prediction of theoretical lumbar lordosis. Correlation analysis between the different parameters was performed. All parameters were correlated with spinal malalignment but LLI is the most correlated parameter (r = -0.978). It is also the best parameter in this study to predict the need of a spinal osteotomy (r = 1 if LLI <0.5). LLI is a statistically validated parameter for sagittal malalignment analysis. It can be used as a mathematical tool to detect spinal malalignment in adult scoliosis and guides the surgeon decision of realizing a vertebral osteotomy for adult scoliosis sagittal correction. It can be used as well for the interpretation of clinical series in adult scoliosis.

Cross-sectional study, with retrospective data collection. Homogenous groups of 68 persons (43 women) aged 30.10 (25-39) years, with mild or moderate scoliosis, and 76 (38 women) able-bodied persons, aged 30.11 (24-38) years, who 16.5 (12-26) years earlier had completed scoliosis-specific exercise or observation regimes, participated. Their respiratory characteristics did not differ from predicted values. The WHOQOL-BREF questionnaire, Oswestry Disability Questionnaire, and pain scale (VAS) were applied. The transformed WHOQOL-BREF scores ranged from 54.6 ± 11.19 in the physical domain in the mild scoliotic subgroup to 77.1 ± 16.05 in the social domain in the able-bodied subgroup. The ODQ values did not generally exceed 5.3 ± 7.53. Inter- and intragroup differences were nonsignificant. Age, marital status, education, and gender were significantly associated with the ODQ scores. Significant association between the ODQ and WHOQOL-BREF social relationships domain scores with the participation in exercise treatment was found. Participants with the history of exercise treatment generally did not differ significantly from their peers who were only under observation. This study cannot conclude that scoliosis-specific exercise treatment in adolescence alters quality of life in adulthood.

Scoliosis affects up to 6 % of the population. The resulting spine deformity, the increasing risk of back pain, cosmetic aspects, pulmonary disorders if the Cobb angle is > 80°, and the progress of the deformity to > 50° after the end of growth indicate non-operative or operative therapy. In daily clinical practice, the classifications of scoliosis allow the therapy to be adapted. Classifications consider deformity, topography of the scoliosis, and the age at diagnosis. This publication gives an overview of the relevant and most common classifications in the treatment of adolescent scoliosis. For evaluation, the deformity measurement on the coronary radiographic projection of the total spine (Cobb angle) is relevant to therapy. The classification of topography, form, and the sagittal profile of the deformity of the spine are useful for preoperative planning of the fusion level. Classifications that take into account the age at the time of the diagnosis of scoliosis differentiate among early onset scoliosis (younger than 10 years of age), adolescent scoliosis (up to the end of growth), and adult scoliosis. Early onset scoliosis is subdivided by age and etiology. Therapy is derived from the classification of clinical and radiological findings. Classifications that take into account clinical and radiological parameters are essential components of modern scoliosis therapy.

Previous studies have confirmed that patients with mandibular deviation often have abnormal morphology of their cervical vertebrae. However, the relationship between mandibular deviation, scoliosis, and trunk balance has not been studied. Currently, mandibular deviation is usually treated as a single pathology, which leads to poor clinical efficiency. We investigated the relationship of spine coronal morphology and trunk balance in adult patients with mandibular deviation, and compared the finding to those in healthy volunteers. 35 adult patients with skeletal mandibular deviation and 10 healthy volunteers underwent anterior X-ray films of the head and posteroanterior X-ray films of the spine. Landmarks and lines were drawn and measured on these films. The axis distance method was used to measure the degree of scoliosis and the balance angle method was used to measure trunk balance. The relationship of mandibular deviation, spine coronal morphology and trunk balance was evaluated with the Pearson correlation method. The spine coronal morphology of patients with mandibular deviation demonstrated an “S” type curve, while a straight line parallel with the gravity line was found in the control group (significant difference, p<0.01). The trunk balance of patients with mandibular deviation was disturbed (imbalance angle >1°), while the control group had a normal trunk balance (imbalance angle <1°). There was a significant difference between the two groups (p<0.01). The degree of scoliosis and shoulder imbalance correlated with the degree of mandibular deviation, and presented a linear trend. The direction of mandibular deviation was the same as that of the lateral bending of thoracolumbar vertebrae, which was opposite to the direction of lateral bending of cervical vertebrae. Our study shows the degree of mandibular deviation has a high correlation with the degree of scoliosis and trunk imbalance, all the three deformities should be clinically evaluated in the

To evaluate the effects of motor and cognitive rehabilitation on disability in adults with idiopathic scoliosis at lower risk of progression. 130 adults with idiopathic scoliosis (main curve <35°) were randomly assigned to a 20-week rehabilitation programme consisting of active self-correction, task-oriented exercises and cognitive-behavioural therapy (experimental group, 65 subjects, mean age of 51.6, females 48) or general physiotherapy consisting of active and passive mobilizations, stretching, and strengthening exercises of the spinal muscles (control group, 65 subjects, mean age of 51.7, females 46). Before, at the end, and 12 months after treatment, each participant completed the Oswestry disability index (ODI) (primary outcome), the Tampa scale for kinesiophobia, the pain catastrophizing scale, a pain numerical rating scale, and the Scoliosis Research Society-22 Patient Questionnaire. Radiological (Cobb angle) and clinical deformity (angle of trunk rotation) changes were also investigated. A linear mixed model for repeated measures was used for each outcome. Significant effects of time, group, and time by group interaction were found for all outcome measures (P < 0.001). After training, the primary outcome showed a clinically significant between-group change (12 % points), which was preserved at follow-up. At follow-up, the radiological deformities showed a significant, although not clinically meaningful, between-group difference of 4° in favour of the experimental group. The experimental programme was superior to general physiotherapy in reducing disability of adults with idiopathic scoliosis. Motor and cognitive rehabilitation also led to improvements in dysfunctional thoughts, pain, and quality of life. Changes were maintained for at least 1 year.

With the aging of the population, degenerative scoliosis (DS) incidence rate is increasing. In recent years, increasing research on this topic has been carried out, yet biomechanical research on the subject is seldom seen and in vitro biomechanical model of DS nearly cannot be available. The objective of this study was to develop and validate a complete three-dimensional finite element model of DS in order to build the digital platform for further biomechanical study. A 55-year-old female DS patient (Suer Pan, ID number was P141986) was selected for this study. This study was performed in accordance with the ethical standards of Declaration of Helsinki and its amendments and was approved by the local ethics committee (117 hospital of PLA ethics committee). Spiral computed tomography (CT) scanning was conducted on the patient's lumbar spine from the T12 to S1. CT images were then imported into a finite element modeling system. A three-dimensional solid model was then formed from segmentation of the CT scan. The three-dimensional model of each vertebra was then meshed, and material properties were assigned to each element according to the pathological characteristics of DS. Loads and boundary conditions were then applied in such a manner as to simulate in vitro biomechanical experiments conducted on lumbar segments. The results of the model were then compared with experimental results in order to validate the model. An integral three-dimensional finite element model of DS was built successfully, consisting of 113,682 solid elements, 686 cable elements, 33,329 shell elements, 4968 target elements, 4968 contact elements, totaling 157,635 elements, and 197,374 nodes. The model accurately described the physical features of DS and was geometrically similar to the object of study. The results of analysis with the finite element model agreed closely with in vitro experiments, validating the accuracy of the model. The three-dimensional finite element model of DS built in

Reversal of childhood idiopathic scoliosis in an adult, without surgery: a case report and literature review

PubMed Central

2009-01-01

Background Some patients with mild or moderate thoracic scoliosis (Cobb angle <50-60 degrees) suffer disproportionate impairment of pulmonary function associated with deformities in the sagittal plane and reduced flexibility of the spine and chest cage. Long-term improvement in the clinical signs and symptoms of childhood onset scoliosis in an adult, without surgical intervention, has not been documented previously. Case presentation A diagnosis of thoracic scoliosis (Cobb angle 45 degrees) with pectus excavatum and thoracic hypokyphosis in a female patient (DOB 9/17/52) was made in June 1964. Immediate spinal fusion was strongly recommended, but the patient elected a daily home exercise program taught during a 6-week period of training by a physical therapist. This regime was carried out through 1992, with daily aerobic exercise added in 1974. The Cobb angle of the primary thoracic curvature remained unchanged. Ongoing clinical symptoms included dyspnea at rest and recurrent respiratory infections. A period of multimodal treatment with clinical monitoring and treatment by an osteopathic physician was initiated when the patient was 40 years old. This included deep tissue massage (1992-1996); outpatient psychological therapy (1992-1993); a daily home exercise program focused on mobilization of the chest wall (1992-2005); and manipulative medicine (1994-1995, 1999-2000). Progressive improvement in chest wall excursion, increased thoracic kyphosis, and resolution of long-standing respiratory symptoms occurred concomitant with a >10 degree decrease in Cobb angle magnitude of the primary thoracic curvature. Conclusion This report documents improved chest wall function and resolution of respiratory symptoms in response to nonsurgical approaches in an adult female, diagnosed at age eleven years with idiopathic scoliosis.

There is a paucity of information on the pre-operative coronal imbalance in patients with degenerative lumbar scoliosis (DLS) and its influence on surgical outcomes. A total of 284 DLS patients were recruited into this study, among whom 69 patients were treated surgically and the remaining 215 patients conservatively Patients were classified based on the coronal balance distance (CBD): Type A, CBD < 3 cm; Type B, CBD > 3 cm and C7 Plumb Line (C7PL) shifted to the concave side of the curve; Type C, CBD > 3 cm and C7PL shifted to the convex side. A total of 99 of the 284 (34.8%) patient presented with a pre-operative coronal imbalance (mean CBD: 48.5, standard deviation 18.7 mm). More patients with a Type B malalignment were observed than with a Type C malalignment (62 versus 37). A total of 21 pf the 69 (30.4%) surgically treated patients had a post-operative coronal imbalance, which was found to be more prevalent in Type C patients (p < 0.001). At follow-up, less improvement was observed in terms of Short Form-36 Physical Component Score and visual analogue score for back pain (p = 0.034 and 0.025, respectively) in Type C patients. This study shows that patients with Type C coronal malalignment may be at greater risk of post-operative coronal imbalance following posterior osteotomy.

Radiographic software measurement analysis in adult scoliosis. To assess the accuracy as well as the intra- and interobserver reliability of measuring different indices on preoperative adult scoliosis radiographs using a novel measurement software that includes a calibration procedure and semiautomatic features to facilitate the measurement process. Scoliosis requires a careful radiographic evaluation to assess the deformity. Manual and computer radiographic process measures have been studied extensively to determine the reliability and reproducibility in adolescent idiopathic scoliosis. Most studies rely on comparing given measurements, which are repeated by the same user or by an expert user. A given measure with a small intra- or interobserver error might be deemed as good repeatability, but all measurements might not be truly accurate because the ground-truth value is often unknown. Thorough accuracy assessment of radiographic measures is necessary to assess scoliotic deformities, compare these measures at different stages or to permit valid multicenter studies. Thirty-four sets of adult scoliosis digital radiographs were measured two times by three independent observers using a novel radiographic measurement software that includes semiautomatic features to facilitate the measurement process. Twenty different measures taken from the Spinal Deformity Study Group radiographic measurement manual were performed on the coronal and sagittal images. Intra- and intermeasurer reliability for each measure was assessed. The accuracy of the measurement software was also assessed using a physical spine model in six different scoliotic configurations as a true reference. The majority of the measures demonstrated good to excellent intra- and intermeasurer reliability, except for sacral obliquity. The standard variation of all the measures was very small: ≤ 4.2° for Cobb angles, ≤ 4.2° for the kyphosis, ≤ 5.7° for the lordosis, ≤ 3.9° for the pelvic angles, and �

To investigate the role of mTOR signaling pathway in bone marrow mesenchymal stem cells (BMSCs) differentiation into osteoblast in degenerative scoliosis (DS). The rat model of DS was established. Thirty-two Sprague-Dawley (SD) rats were selected and divided into the normal control group, the positive control group (normal rats injected with rapamycin), the negative control group (DS rats injected with PBS) and the experiment group (DS rats injected with rapamycin). H&E staining was performed to observe the osteogenesis of scoliosis. The BMSCs were obtained and assigned into seven groups: the normal control group, the positive control group, the negative control group and 1.0/10.0/100.0/1000.0 nmol/L experiment groups. Flow cytometry was conducted to testify cell cycle. The mRNA and protein expressions of mTOR and osteoblastic differentiation markers were measured by qRT-PCR and western blotting. In vivo, compared with the negative control group, bone trabecular area and the number of differentiated bone cells were significantly increased in the experiment groups. In vitro, at 24 and 48 h after rapamycin treatment, compared with the negative control group, BMSCs at G0/G1 stage increased, but BMSCs at S stage decreased in the 1.0/10.0/100.0/1000.0 nmol/L experiment groups; the expressions of mTOR and p70-S6K1 proteins were reduced in the 1.0/10.0/100.0/1000.0 nmol/L experiment groups, while ALP activity, OC levels, calcium deposition, Co1-I protein expression and the mRNA expressions of OC and Co1-I were significantly increased. Suppression of mTOR signaling pathway by rapamycin could promote BMSCs differentiation into osteoblast in DS.

The aim of this paper was to investigate the risk of recurrence of lumbar disc herniation (LDH) in patients with scoliosis who underwent microdiscectomy. A series of consecutive patients who underwent microdiscectomy for LDH was retrospectively reviewed. The inclusion criteria were young adults younger than 40 years who received microdiscectomy for symptomatic 1-level LDH. An exclusion criterion was any previous spinal surgery, including fusion or correction of scoliosis. The patients were divided into 2 groups: those with scoliosis and those without scoliosis. The demographic data in the 2 groups were similar. All medical records and clinical and radiological evaluations were reviewed. A total of 58 patients who underwent 1-level microdiscectomy for LDH were analyzed. During the mean follow-up of 24.6 months, 6 patients (10.3%) experienced a recurrence of LDH with variable symptoms. The recurrence rate was significantly higher among the scoliosis group than the nonscoliosis group (33.3% vs. 2.3%, p = 0.001). Furthermore, the recurrence-free interval in the scoliosis group was short. Young adults (< 40 years) with uncorrected scoliosis are at higher risk of recurrent LDH after microdiscectomy.

Single-center, prospective study. Evaluating the responsiveness and minimal important changes (MICs) for the Scoliosis Research Society-22 Patient Questionnaire (SRS-22) in adolescent idiopathic scoliosis (AIS) and adult idiopathic scoliosis (AS). Despite the SRS-22 properties have been investigated in various different languages, there is still a lack of information concerning responsiveness and MIC, limiting the use of SRS-22 for clinical and research purposes. At the beginning and end of multidisciplinary rehabilitation programs, 149 subjects with mild AIS (Cobb angle <25°) and 140 subjects with moderate AS (Cobb angle <35°) completed the SRS-22. Upon completing the programs, subjects also performed the global perceived effect (GPE) scales test, which was divided to produce a dichotomous outcome (improved vs. stable). Responsiveness was calculated for all SRS-22 domains but satisfaction with management by distribution (effect size; standardized response mean) and anchor-based methods (receiver operating characteristic [ROC] curves; correlations between change scores of the SRS-22 and GPE). ROC curves were also used to compute the MICs. The effect size ranged from 1.23 to 1.50 in AIS and from 1.02 to 1.37 in AS. The standardized response mean ranged from 0.95 to 1.27 in AIS and from 0.66 to 0.90 in AS. The ROC analyses revealed the following MIC values (area under the curve; sensitivity; specificity): function, 0.70 (0.739;66;70) for AIS and 0.60 (0.842;84;76) for AS; pain, 0.70 (0.731;71;70) for AIS and 0.40 (0.817;81;70) for AS; mental health, 0.50 (0.708;83;58) for AIS and 0.55 (0.750;69;78) for AS; self-perceived image, 0.40 (0.609;79;42) for AIS and 0.60 (0.751;61;82) for AS. Correlations between change scores of the SRS-22 domains and GPE were low to moderate, ranging from -0.347 to -0.667. The SRS-22 was sensitive in detecting clinical changes in subjects with adolescent and adult scoliosis. We recommend taking the MICs provided into account when

To investigate the change of pulmonary function in adult scoliosis patients with respiratory dysfunction undergoing HGT combined with assisted ventilation. 21 adult patients were retrospectively reviewed with a mean age of 26.2 years. Inclusion criteria were as follows: age over 18 years old; coronal Cobb angle greater than 100°; with respiratory failure; and duration of HGT more than 1 month. All patients underwent respiratory training. The Cobb angle averaged 131.21° and was reduced to 107.68° after HGT. Significantly increased mean forced vital capacity (FVC) was found after HGT (P = 0.003) with significantly improved percent-predicted values for FVC (P < 0.001). Meanwhile, significantly increased forced expiratory volume in 1 s (FEV1) was also observed (P < 0.001) with significantly improved percent-predicted values for FEV1 (P = 0.003) after HGT. The results of our study revealed that combined HGT and assisted ventilation would be beneficial to pulmonary function improvement in severe adult scoliosis cases, most of which were young adults.

To investigate the prevalence of thoracic scoliosis and determine the effect of both age and gender on coronal curve magnitude among asymptomatic adults aged 25-64 years old, using standing posterior-anterior chest radiographs. This was a retrospective, cross-sectional study evaluating 500 randomly selected digital posterior-anterior chest radiographs taken at a single institution on an outpatient basis between January 2010 and December 2011. Males (n = 184) and females (n = 316) ranged in age from 25 to 64 years. Patients with symptoms of back pain; including a history of back pain, spinal instrumentation, or known pre-existing spinal disease were excluded. Radiographs were evaluated using Centricity PACS Web Diagnostic 2.1 system (General Electric Co. Fairfield, CT). Coronal Cobb angle measurements of the thoracic spine were quantified by the authors, with scoliosis defined as coronal curves greater than 10°. Curvatures were subdivided into groups: a control group with coronal curves less than 10°, curves measuring 10° to 19°, 20° to 29°, and greater than 30°. The effect of age and gender on curve magnitude was examined using Pearson correlation analysis and linear regression analysis. There was a 13.4 % (67 patients) prevalence of thoracic scoliosis. The prevalence among asymptomatic males was 10.9 %, while the prevalence among asymptomatic females was 14.9 %. 11.6 % demonstrated a coronal curvature between 10° and 19° (58 patients), 1.6 % between 20° and 29° (8 patients), and 0.2 % greater than 30° (1 patient). Age and gender were not found to be significant independent predictors of curve severity. We found a 13.4 % prevalence of thoracic scoliosis among asymptomatic adults aged 25-64 years on routine outpatient chest radiographs. 11.6 % of patients demonstrated a coronal curvature between 10° and 19°. Unlike prior studies evaluating asymptomatic thoracic curves in elderly patients, age and gender did not significantly affect curve

Appearance concerns in individuals with adolescent idiopathic scoliosis can result in impairment in daily functioning, or body image disturbance. The Body Image Disturbance Questionnaire (BIDQ) is a self-reported, seven-question instrument that measures body image disturbance in general populations; no studies have specifically examined body image disturbance in those with adolescent idiopathic scoliosis. This study aimed to validate a modified version of the BIDQ in a population with adolescent idiopathic scoliosis and to establish discriminant validity by comparing responses of operatively and nonoperatively treated patients with those of normal controls. In the first phase, a multicenter study of forty-nine patients (mean age, fourteen years; thirty-seven female) with adolescent idiopathic scoliosis was performed to validate the BIDQ-Scoliosis version (BIDQ-S). Participants completed the BIDQ-S, Scoliosis Research Society (SRS)-22, Children's Depression Index (CDI), and Body Esteem Scale for Adolescents and Adults (BESAA) questionnaires. Descriptive statistics and Pearson correlation coefficients were calculated. In the second phase, ninety-eight patients with adolescent idiopathic scoliosis (mean age, 15.7 years; seventy-five female) matched by age and sex with ninety-eight healthy adolescents were enrolled into a single-center study to evaluate the discriminant validity of the BIDQ-S. Subjects completed the BIDQ-S and a demographic form before treatment. Independent-sample t tests and Pearson correlation coefficients were calculated. The BIDQ-S was internally consistent (Cronbach alpha = 0.82), and corrected item total correlations ranged from 0.47 to 0.67. The BIDQ-S was significantly correlated with each domain of the SRS-22 and the total score (r = -0.50 to -0.72, p ≤ 0.001), with the CDI (r = 0.31, p = 0.03), and with the BESAA (r = 0.60, p < 0.001). BIDQ-S scores differed significantly between patients (1.50) and controls (1.06, p < 0.005), establishing

This is a retrospective analysis of administrative database. To elucidate the effect of glycemic control on surgical outcomes of middle-aged and elderly idiopathic scoliosis patients undergoing spinal fusion surgery. Diabetes mellitus (DM) is a condition thought to adversely affect outcomes of spine surgery. However, no study has stratified glycemic control levels and their impact on outcome for idiopathic scoliosis patients receiving a spinal fusion surgery. Previous studies may have reported higher than true rates of complications for controlled diabetic patients, who are the majority of diabetic patients. The Nationwide Inpatient Sample was queried from years 2002 to 2011. We extracted idiopathic scoliosis patients older than 45 years of age that received spinal fusion and analyzed complications and outcomes variables among 3 cohorts: nondiabetic patients, controlled diabetics, and uncontrolled diabetics. Multivariate analyses were used to assess whether glycemic control was a risk factor for adverse postoperative outcomes. Controlled diabetics had significantly increased rates of acute renal failure (ARF), while uncontrolled diabetics had significantly increased rates of acute postoperative hemorrhage. In multivariate analyses controlling for patient factors and comorbidities, controlled DM was found to be an independent predictor of ARF [odds ratio (OR), 1.863; 95% confidence interval (CI), 1.346-2.579; P=0.0002), and uncontrolled DM was found to be a significant risk factor for acute postoperative hemorrhage (OR, 2.182; 95% CI, 1.192-3.997; P=0.0115), ARF (OR, 4.839; 95% CI, 1.748-13.392; P=0.0024), deep vein thrombosis (OR, 5.825; 95% CI, 1.329-25.522, P=0.0194) and in-patient mortality (OR, 8.889; 95% CI, 1.001-78.945; P=0.0499). Controlled DM was found to be a risk factor for ARF in adult idiopathic scoliosis patients undergoing spinal fusion surgery, while uncontrolled DM was shown to be a risk factor for postoperative hemorrhage, ARF, deep vein

Retrospective case-control study. The purpose of this study was to compare the self-reported outcomes between operatively and nonoperatively treated patients over the age of 65 with adult scoliosis, using 4 distinct self-assessment questionnaires (SRS-22, SF-12, EQ5D, and Oswestry disability index [ODI]) and standard radiographic measurement parameters. The current spine literature contains no studies that directly compare the self-reported and radiographic outcomes of operatively and nonoperatively treated patients over the age of 65 years with adult scoliosis. We retrospectively analyzed the self-reported outcomes of 83 adult scoliosis in patients over the age of 65 years. A total of 34 patients were treated operatively, whereas 49 patients were managed nonoperatively. For each of these patients, standard radiographic measurements were recorded both before and after treatment, and each patient received 4 questionnaires (SRS-22, SF-12, EQ5D, and ODI) that were completed with a minimum of 2-year follow-up from the time the treatment was initiated. The outcomes of both groups were then statistically compared. As compared to the nonoperative group, the operative group reported significantly better self-assessment scores for the EQ5D index, EQ5D Visual Analogue Score, and SRS-22 questionnaires. However, no statistically significant difference between the groups was detected for the ODI, SF-12 Mental Health Component Summary, and SF-12 PCS. Furthermore, the operative group also had a significant improvement in radiographic measurements. Adult scoliosis patients over the age of 65 years treated operatively had significantly less pain, a better health-related quality of life, self image, mental health, and were more satisfied with their treatment than patients treated conservatively. However, we found no statistically significant differences in their degree of disability as measured by the ODI as well as physical and mental health by the SF-12 instrument. Preoperative

Combined anteroposterior spinal fusion with instrumentation has been used for many years to treat adult thoracolumbar/lumbar scoliosis. This surgery remains a technical challenge to spine surgeons, and current literature reports high complication rates. The purpose of this study is to validate a new hybrid technique (a combination of single-rod anterior instrumentation and a shorter posterior instrumentation to the sacrum) to treat adult thoracolumbar/lumbar scoliosis. This study is a retrospective consecutive case series of surgically treated patients with adult lumbar or thoracolumbar scoliosis. This is a retrospective study of 33 matched pairs of patients with adult scoliosis who underwent two different surgical procedures: a new hybrid technique versus a third-generation anteroposterior spinal fusion. Preoperative and postoperative outcome measures include self-report measures, physiological measures, and functional measures. In a retrospective case-control study, 33 patients treated with the hybrid technique were matched with 33 patients treated with traditional anteroposterior fusion based on preoperative radiographic parameters. Mean follow-up in the hybrid group was 5.3 years (range, 2-11 years), compared with 4.6 years (range, 2-10 years) in the control group. Operating room (OR) time, estimated blood loss, and levels fused were collected as surrogates for surgical morbidity. Radiographic parameters were collected preoperatively, postoperatively, and at final follow-up. The Scoliosis Research Society Patient Questionnaire (SRS-22r) and Oswestry Disability Index (ODI) scores were collected for clinical outcomes. Operating room time, EBL, and levels fused were significantly less in the hybrid group compared with the control group (p<.0001). The postoperative thoracic Cobb angle was similar between the hybrid and control techniques (p=.24); however, the hybrid technique showed significant improvement in the thoracolumbar/lumbar curves (p=.004) and the

A population-based study. To study the prevalence and features of symptomatic degenerative lumbar osteoarthritis in adults. Lumbar osteoarthritis adversely affects individuals and is a heavy burden. There are limited data on the prevalence of lumbar osteoarthritis. A representative, multistage sample of adults was collected. Symptomatic degenerative lumbar osteoarthritis was diagnosed by clinical symptoms, physical examinations, and imaging examinations. Personal information was obtained by face-to-face interview. Information included the place of residence, age, sex, income, type of medical insurance, education level, body mass index, habits of smoking and drinking, type of work, working posture, duration of the same working posture during the day, mode of transportation, exposure to vibration, and daily amount of sleep. Crude and adjusted prevalence was calculated. The features of populations were analyzed by multivariable logistic regression in total and subgroup populations. The study included 3859 adults. The crude and adjusted prevalence of lumbar osteoarthritis was 9.02% and 8.90%, respectively. There was no significant difference in the prevalence of lumbar osteoarthritis between urban, suburban, and rural populations (7.66%, 9.97%, and 9.44%) (P = 0.100). The prevalence of lumbar osteoarthritis was higher in females (10.05%) than in males (9.1%, P = 0.021). The prevalence of lumbar osteoarthritis increased with increasing age. Obese people (body mass index >28 kg/m), those engaged in physical work, those who maintained the same work posture for 1 to 1.9 hours per day, those who were exposed to vibration during daily work, and those who got less than 7 hours of sleep per day had a higher prevalence. These features differed by subgroup. This study established epidemiological baseline data for degenerative lumbar osteoarthritis in adults, especially for people younger than 45 years.

The effect of myofascial release (MFR) on an adult with idiopathic scoliosis.

PubMed

LeBauer, Aaron; Brtalik, Robert; Stowe, Katherine

2008-10-01

The lack of evidence of conservative treatment has led to an interest in exploring myofascial release (MFR) as an effective means of controlling spinal curvature progression in adolescents with idiopathic scoliosis. The purpose of this case study is to measure the effects of MFR as a manual therapy technique in the treatment of idiopathic scoliosis. One 18-year-old female subject underwent 6 weeks of MFR treatment consisting of two sessions each week for 60min. Pain, pulmonary function, and quality of life were measured. Six goniometric measurements were taken encompassing trunk flexion, extension, and rotation. The subject improved with pain levels, trunk rotation, posture, quality of life, and pulmonary function. The results suggest further investigation is needed using MFR, as an effective manual therapy treatment for idiopathic scoliosis.

[Purpose] For adult patients with late-onset idiopathic scoliosis, cosmetic concerns and pain are the main reasons for seeking treatment at a physician’s office. The purpose of this paper was to describe the mid-term effect of physical rehabilitation and part-time bracing on an adult scoliosis patient who had been suffering from chronic low back pain for fourteen years. [Subject and Methods] Case description: A 37-year-old female patient with late-onset idiopathic scoliosis presented in the office of the first author in January 2014. She reported having chronic pain (low back pain) since the age of 23 and reported daily pain at a level of 5–7 on average on a Visual Analogue Scale of 0 to 10. She received a short scoliosis-specific Schroth exercise program and was also fitted with a Gensingen brace for part-time wear. [Results] At a 16 month follow-up, the patient no longer suffered from daily low back pain (with heavy lifting only) and was fully active. Additionally, her lumbar Cobb angle and angle of trunk rotation improved. [Conclusion] Patients with late-onset idiopathic scoliosis and pain may benefit from a pattern-specific conservative treatment approach. In this population, surgical intervention should be regarded as the last resort, since there are many long-term unknowns with surgery. PMID:27630444

To explore the surgical indications, decompression and fusion method, and fusion level selection of degenerative lumbar scoliosis (DLS) and multi-segment lumbar spinal stenosis. Between April 2000 and November 2011, 46 cases of DLS and multi-segment lumbar spinal stenosis were treated with multi-level decompression by fenestration and crept enlargement plus internal fixation by interbody and posterior-lateral bone graft fusion (5 segments or above). Of 46 cases, 25 were male and 21 were female, with a mean age of 70.2 years (range, 65-81 years) and with a mean disease duration of 6.4 years (range, 4 years and 6 months to 13 years). X-ray films showed that the lumbar Cobb angle was (26.7 ± 10.0) degrees, and the lumbar lordotic angle was (20.3 ± 8.8)degrees. The lumbar CT and MRI images showed three-segment stenosis in 24 cases, four-segment stenosis in 17 cases, and five-segment stenosis in 5 cases. A total of 165 stenosed segments included 12 L1,2, 34 L2,3, 43 L3,4, 45 L4,5, and 31 L5 and S1. Visual analogue scale (VAS) score, Oswestry disability index (ODI), and Japanese Orthopedic Association (JOA) score (29 points) were employed to evaluate effectiveness. Thirteen patients had leakage of cerebrospinal fluid during operation, and no infection was found after corresponding treatment; pulmonary infection and urinary system infection occurred in 4 and 2 patients respectively, who relieved after received antibiotic therapy; 8 patients with poor wound healing received dressing change, adequate drainage, debridement and suture. No death, paralysis, central nervous system infection, or other complication was observed in these patients. Forty-six cases were followed up 12-72 months (mean, 36.2 months). Lumbago and backache and intermittent claudication of lower extremity were obviously improved. During follow-up, no screw incising, loosening and broken screws, or pseudarthrosis was noted under X-ray film and CT scanning. At last follow-up, the lumbar Cobb angle was

Little is known about the long-term status of patients operated for spine deformities. The aim of this study was to determine the survival of primary fusion in adult idiopathic scoliosis and identify the risk factors of revision surgery. Adult patients who underwent primary fusion for idiopathic scoliosis between 1983 and 2011 were included in a continuous monocentric retrospective series. Any additional surgery was registered for survival analysis. Survival and follow-up were estimated by the Kaplan-Meier method and an analysis was performed to identify the risk factors of revision surgery. This series included 447 women (86.5 %) and 70 men (13.5 %) reviewed after a mean follow-up of 7 years (range 0-26.4). Mean age was 44.4 years. Fusion was performed on a median 11 levels (range 3-15); revision rate was 13 % (CI 10-17), 18 % (CI 14-23) and 20 % (CI 16-26) at 5, 10 and 15 years, respectively. Revision surgery was associated with age, anterior release, length of fusion, the inferior limit of fusion, post-operative sagittal balance and junctional kyphosis. The length of fusion (HR 1.13 per vertebrae fused, p = 0.007) and the lower limit of fusion (HR 5.9, p < 0.001) remained independent predictors of revision surgery on multivariate analysis. This series evaluated the risk of revision surgery following spinal fusion for idiopathic scoliosis. Our results show that the risk seemed to increase linearly with a rate of nearly 20 % after 10 years. The length and lower limit of fusion are the main risk factors for revision surgery.

According to the Scoliosis Research Society (SRS), idiopathic scoliosis (IS) is a curvature of more than 10° Cobb angle, affecting 2-3% of pediatric population. Idiopathic scoliosis accounts for 80% of all scoliosis cases. Non-operative principles in the therapy of idiopathic scoliosis, including Scoliosis Research Society (SRS) criteria and guidelines proposed by the experts of the Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORTS) were presented. The possibility to carry out quality of life assessments in a conservative procedure was also demonstrated. Based on the natural history of idiopathic scoliosis, SRS criteria, SOSORT 2008 experts' opinion and the knowledge of the possibilities of psychological assessment of conservative IS treatment, rules were proposed regarding nonsurgical IS therapy procedures, with special consideration being paid to the proper treatment start time (age, Risser test, biological maturity, Cobb angle), possibility of curvature progression, the importance of physiotherapy and psychological assessment. The knowledge of SRS criteria and SOSORT guidelines regarding the conservative treatment of IS are essential for proper treatment (the right time to start treatment), and supports establishment of interdisciplinary treatment teams, consisting of a physician, a physiotherapist, an orthopedic technician and a psychologist.

Physiotherapeutic scoliosis-specific exercises for adolescents with idiopathic scoliosis.

2014-02-01

The use of exercises for the treatment of Adolescents with Idiopathic Scoliosis is controversial. Whilst exercises are routinely used in a number of central and southern European countries, most centres in the rest of the world (mainly in Anglo-Saxon countries), do not advocate its use. One of the reasons for this is that many health care professionals are usually not conversant with the differences between generalised physiotherapy exercises and physiotherapeutic scoliosis-specific exercises (PSSE): while the former are generic exercises usually consisting of low-impact stretching and strengthening activities like yoga, Pilates and the Alexander technique, PSSE consist of a program of curve-specific exercise protocols which are individually adapted to a patients' curve site, magnitude and clinical characteristics. PSSEs are performed with the therapeutic aim of reducing the deformity and preventing its progression. It also aims to stabilise the improvements achieved with the ultimate goal of limiting the need for corrective braces or the necessity of surgery. This paper introduces the different 'Schools' and approaches of PSSE currently practiced (Scientific Exercise Approach to Scoliosis - SEAS, Schroth, Barcelona Scoliosis Physical Therapy School - BSPTS, Dobomed, Side Shift, Functional Individual Therapy of Scoliosis - FITS and Lyon) and discusses their commonalities and differences.

Lumbar degenerative spinal deformity: Surgical options of PLIF, TLIF and MI-TLIF

PubMed Central

Hey, Hwee Weng Dennis; Hee, Hwan Tak

2010-01-01

Degenerative disease of the lumbar spine is common in ageing populations. It causes disturbing back pain, radicular symptoms and lowers the quality of life. We will focus our discussion on the surgical options of posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for lumbar degenerative spinal deformities, which include symptomatic spondylolisthesis and degenerative scoliosis. Through a description of each procedure, we hope to illustrate the potential benefits of TLIF over PLIF. In a retrospective study of 53 ALIF/PLIF patients and 111 TLIF patients we found reduced risk of vessel and nerve injury in TLIF patients due to less exposure of these structures, shortened operative time and reduced intra-operative bleeding. These advantages could be translated to shortened hospital stay, faster recovery period and earlier return to work. The disadvantages of TLIF such as incomplete intervertebral disc and vertebral end-plate removal and potential occult injury to exiting nerve root when under experienced hands are rare. Hence TLIF remains the mainstay of treatment in degenerative deformities of the lumbar spine. However, TLIF being a unilateral transforaminal approach, is unable to decompress the opposite nerve root. This may require contralateral laminotomy, which is a fairly simple procedure. The use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) to treat degenerative lumbar spinal deformity is still in its early stages. Although the initial results appear promising, it remains a difficult operative procedure to master with a steep learning curve. In a recent study comparing 29 MI-TLIF patients and 29 open TLIF, MI-TLIF was associated with longer operative time, less blood loss, shorter hospital stay, with no difference in SF-36 scores at six months and two years. Whether it can replace traditional TLIF as the surgery of choice for

2012-01-01

Background Studies investigating the outcome of conservative scoliosis treatment differ widely with respect to the inclusion criteria used. This study has been performed to investigate the possibility to find useful inclusion criteria for future prospective studies on physiotherapy (PT). Materials and methods A PubMed search for outcome papers on PT was performed in order to detect study designs and inclusion criteria used. Results Real outcome papers (start of treatment in immature samples/end results after the end of growth; controlled studies in adults with scoliosis with a follow-up of more than 5 years) have not been found. Some papers investigated mid-term effects of exercises, most were retrospective, few prospective and many included patient samples with questionable treatment indications. Conclusion There is no outcome paper on PT in scoliosis with a patient sample at risk for being progressive in adults or in adolescents followed from premenarchial status until skeletal maturity. However, papers on bracing are more frequently found and bracing can be regarded as evidence-based in the conservative management and rehabilitation of idiopathic scoliosis in adolescents.

Quantifying torso deformity in scoliosis

NASA Astrophysics Data System (ADS)

Ajemba, Peter O.; Kumar, Anish; Durdle, Nelson G.; Raso, V. James

2006-03-01

Scoliosis affects the alignment of the spine and the shape of the torso. Most scoliosis patients and their families are more concerned about the effect of scoliosis on the torso than its effect on the spine. There is a need to develop robust techniques for quantifying torso deformity based on full torso scans. In this paper, deformation indices obtained from orthogonal maps of full torso scans are used to quantify torso deformity in scoliosis. 'Orthogonal maps' are obtained by applying orthogonal transforms to 3D surface maps. (An 'orthogonal transform' maps a cylindrical coordinate system to a Cartesian coordinate system.) The technique was tested on 361 deformed computer models of the human torso and on 22 scans of volunteers (8 normal and 14 scoliosis). Deformation indices from the orthogonal maps correctly classified up to 95% of the volunteers with a specificity of 1.00 and a sensitivity of 0.91. In addition to classifying scoliosis, the system gives a visual representation of the entire torso in one view and is viable for use in a clinical environment for managing scoliosis.

To determine any differences between the prevalence of adolescent idiopathic scoliosis in ballet dancers who are girls compared with age-matched nondancers, and to establish if any relations exist between the presence of scoliosis and generalized joint hypermobility, age of menarche, body mass index (BMI), and the number of hours of dance training per week. Cross-sectional, matched pair study. Dance school. Dancers (n=30) between the ages of 9 and 16 years were recruited from a certified dance school in Western Australia; each dancer provided a consenting age-matched nondancer (n=30). Not applicable. Measurements were taken for angle of trunk rotation using a scoliometer (presence of scoliosis) and for height and weight to produce generalized joint hypermobility using Beighton criteria and an age-adjusted BMI, respectively. A subjective questionnaire regarding age of menarche and participation in dance and other sports was completed. Thirty percent of dancers tested positive for scoliosis compared with 3% of nondancers. Odds ratio calculations suggest that dancers were 12.4 times more likely to have scoliosis than nondancers of the same age. There was a higher rate of hypermobility in the dancer group (70%) compared with the nondancers (3%); however, there were no statistically significant relations between scoliosis and hypermobility, age of menarche, BMI, or hours of dance per week. Adolescent dancers, similar to adult dancers, are at significantly higher risk of developing scoliosis than nondancers of the same age. Vigilant screening and improved education of dance teachers and parents of dance students may be beneficial in earlier detection and, consequently, reducing the risk of requiring surgical intervention.

The objective of this study was to describe the posture patterns of adolescents diagnosed with adolescent idiopathic scoliosis (AIS) in a scoliosis school screening (SSS). Two-dimensional photogrammetry was used to assess the posture of 37 adolescents diagnosed with scoliosis (scoliosis group, SG) (Cobb angle ≥10°) and 76 adolescents with a false positive diagnosis (false positive group, FPG) (Cobb angle <10°, angle of trunk rotation ≥7°). In total, 2562 10- to 14-year-old adolescents were enrolled in the SSS, which was performed in public schools in the cities of Amparo, Pedreira, and Mogi Mirim in the state of São Paulo, Brazil. Their posture was analyzed using Postural Analysis Software. Continuous variables were tested using Student t test, and categorical variables were tested using a χ2 test. The SG, FPG, simple curve group, and double curve group were all compared. Bivariate analysis was used to identify associations between postural deviations and scoliosis. The adopted significance level was α = .05. The SG (2.7 ± 1.9°) had greater shoulder obliquity than the FPG (1.9 ± 1.4°) (P = .010), and this deviation was associated with scoliosis (odds ratio [95% CI] P = 1.4 [1.1-1.8] 0.011). The SG had asymmetry between the right- and left-side lower limb frontal angle, shoulder sagittal alignment, and knee angle. The double curve group (3 ± 1.7°) presented a greater value of the vertical alignment of the torso than the simple curve group did (1.9 ± 1°; P = .032). Adolescents diagnosed with AIS in an SSS had greater shoulder obliquity and asymmetry between the right and left sides. Shoulder obliquity was the only postural deviation associated with AIS.

A prospective randomized study was conducted. The purpose of this study was to assess the radiographic outcomes of one-level minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) with unilateral pedicle screw instrumentation for degenerative lumbar spine disease. MI-TLIF has become an increasingly popular method of lumbar arthrodesis. Recent technological advances in spinal instrumentation have culminated in the development of MI-TLIF with unilateral pedicle screw fixation. However, there are few published studies on radiographic outcomes of the MI-TLIF with unilateral pedicle screw fixation. A total of 65 patients with one-level degenerative lumbar spine disease were enrolled in this study. Patients were randomized into the unilateral or bilateral fixation group based on a computer-generated number list. Thirty-one patients (17 men and 14 women; average age, 57.3 y) were randomized to the unilateral group (group A) and 34 patients (16 men and 18 women; average age, 58.9 y) to the bilateral group (group B). All patients underwent minimally invasive decompression, interbody fusion, and pedicle screw fixation with the assistance of microscopic tubular retractor system (METRx-MD) and Sextant system. All patients were asked to follow-up at 3, 6, and thereafter once every 6 months after surgery. The visual analog scale (VAS), Oswestry disability index (ODI), and modified Prolo (mProlo) scores were obtained for all patients 24 hours before the operation and at each follow-up visit. The whole lumbar lordosis (WL), the segmental lordosis (SL), fusion level disk space angle, lumbar scoliosis angle, and segmental scoliosis angle were determined before and after surgery on standard x-rays. The disk height index (DI) and the lumber curvature index (LI) were also evaluated. The mean follow-up was 26.6 months, with a range of 18-36 months. All patients showed evidence of fusion at 12 months postoperatively. Statistically, there was no significant difference between

The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.

A comparison of measurements of degenerative spondylolisthesis made on film and on computer workstations. To determine whether the 2 methodologies are comparable in some of the parameters used to assess lumbar degenerative spondylolisthesis. Digital radiology has been replacing analog radiographs. In scoliosis, several studies have shown that measurements made on digital and analog films are similar and that they are also similar to those made on computer workstations. Such work has not been done in spondylolisthesis. Twenty-four cases of lumbar degenerative spondylolisthesis were identified from our clinic practice. Three observers measured anterior displacement, sagittal rotation, and lumbar lordosis on digital films using the same protractor and pencil. The same parameters were measured on the same studies at clinical workstations. All measurements were repeated 2 weeks later. A statistician determined the intra and interobserver reliability of the 2 measurement methods and the degree of agreement between the 2 methods. The differences between the first and second readings did reach statistical significance in some cases, but none of them were large enough to be clinically meaningful. The interclass correlation coefficients (ICCs) were >or=0.80 except for one (0.67). The difference among the 3 observers was similarly statistically significant in a few instances but not enough to influence clinical decisions and with good ICCs (0.67 and better). Similarly, the differences in the 2 methods were small, and ICCs ranged from 0.69 to 0.98. This study supports the use of computer workstation measurements in lumbar degenerative spondylolisthesis. The parameters used in this study were comparable, whether measured on film or at clinical workstations.

OBJECTIVE: This study assessed the prevalence of scoliosis and the patterns of scoliotic curves in patients with Williams-Beuren syndrome. Williams-Beuren syndrome is caused by a chromosome 7q11.23 deletion in a region containing 28 genes, with the gene encoding elastin situated approximately at the midpoint of the deletion. Mutation of the elastin gene leads to phenotypic changes in patients, including neurodevelopmental impairment of varying degrees, characteristic facies, cardiovascular abnormalities, hypercalcemia, urological dysfunctions, and bone and joint dysfunctions. METHODS: A total of 41 patients diagnosed with Williams-Beuren syndrome, who were followed up at the genetics ambulatory center of a large referral hospital, were included in the study. There were 25 male subjects. The patients were examined and submitted to radiographic investigation for Cobb angle calculation. RESULTS: It was observed that 14 patients had scoliosis; of these 14 patients, 10 were male. The pattern of deformity in younger patients was that of flexible and simple curves, although adults presented with double and triple curves. Statistical analysis showed no relationships between scoliosis and age or sex. CONCLUSION: This study revealed a prevalence of scoliosis in patients with Williams-Beuren syndrome of 34.1%; however, age and sex were not significantly associated with scoliosis or with the severity of the curves.

Scoliosis is prominent in Rett syndrome (RTT). Following the prior report from the US Natural History Study, the onset and progression of severe scoliosis (≥40° Cobb angle) and surgery were examined regarding functional capabilities and specific genotypes, addressing the hypothesis that abnormal muscle tone, poor oral feeding, puberty, and delays or absence of sitting balance and ambulation may be responsible for greater risk in RTT. The multicenter RTT Natural History Study gathered longitudinal data for classic RTT, including mutation type, scoliosis, muscle tone, sitting, ambulation, hand function, and feeding. Cox regression models were used to examine the association between scoliosis and functional characteristics. All analyses utilized SAS 9.4; two-sided P values of <0.05 were considered significant. A total of 913 females with classic RTT were included. Scoliosis frequency and severity increased with age. Severe scoliosis was found in 251 participants (27%), 113 of whom developed severe scoliosis during the follow-up assessments; 168 (18%) had surgical correction. Severe MECP2 mutations (R106W, R168X, R255X, R270X, and large deletions) showed a higher proportion of scoliosis. Individuals developing severe scoliosis or requiring surgery were less likely to sit, ambulate, or use their hands and were more likely to have begun puberty. Significant differences were absent for epilepsy rates, sleep problems, or constipation. Scoliosis requires vigilance regarding the risk factors noted, particularly specific mutations and the role of puberty and motor abilities. Bracing is recommended for moderate curves and surgery for severe curves in accordance with published guidelines for scoliosis management. Copyright © 2017 Elsevier Inc. All rights reserved.

PURPOSE OF THE STUDY The aim of the study was to compare the duration of corrective surgery for scoliosis in relation to the intra-operative use of either fluoroscopic or CT navigation. MATERIAL AND METHODS The indication for surgery was adolescent idiopathic scoliosis in younger patients and degenerative scoliosis in middleage or elderly patients. In a retrospective study, treatment outcomes in 43 consecutive patients operated on between April 2011 and April 2014 were compared. Only patients undergoing surgical correction of five or more spinal segments (fixation of six and more vertebrae) were included. RESULTS Transpedicular screw fixation of six to 13 vertebrae was performed under C-arm fluoroscopy guidance in 22 patients, and transpedicular screws were inserted in six to 14 vertebrae using the O-arm imaging system in 21 patients. A total of 246 screws were placed using the C-arm system and 340 screws were inserted using the O-arm system (p < 0.001). The procedures with use of the O-arm system were more complicated and required an average operative time longer by 48% (measured from the first skin incision to the completion of skin suture). However, the mean time needed for one screw placement (the sum of all surgical procedures with the use of a navigation technique divided by the number of screws placed using this technique) was the same in both techniques (19 min). DISCUSSION With good teamwork (surgeons, anaesthesiologists and a radiologist attending to the O-arm system), the time required to obtain one intra-operative CT scan is 3 to 5 minutes. The study showed that the mean time for placement of one screw was identical in both techniques although the average operative time was longer in surgery with O-arm navigation. The 19- minute interval was not the real placement time per screw. It was the sum of all operative times of surgical procedures (from first incision to suture completion including the whole approach within the range of planned stabilization

The aim of the study was to provide a meta-analysis of current literature concerning the natural history of idiopathic scoliosis during growth. A comprehensive search of Medline, Embase, And Scopus databases was conducted up to November 2016. Eligible works were prospective or retrospective studies that enrolled patients with infantile idiopathic scoliosis, juvenile idiopathic scoliosis, or adolescent idiopathic scoliosis, followed up without any treatment from the time of detection. A meta-analysis for proportion was performed. The following studies were grouped per diagnosis: infantile idiopathic scoliosis, juvenile idiopathic scoliosis, and adolescent idiopathic scoliosis. Of the 1797 citations screened, we assessed 61 full-text articles and included 13 of these (2301 participants). Three studies included infantile idiopathic scoliosis patients (347 participants), five studies included a mixed population of juvenile idiopathic scoliosis and adolescent idiopathic scoliosis (1330 participants), and five studies included adolescent idiopathic scoliosis patients only (624 participants). The random pooled estimated progression rate was 49% (95% confidence interval = 1%-97%) for infantile idiopathic scoliosis, 49% in a mixed group of patients affected by juvenile idiopathic scoliosis or adolescent idiopathic scoliosis (95% confidence interval = 19%-79%), and 42% in adolescent idiopathic scoliosis (95% confidence interval = 11%-73%). During growth, idiopathic scoliosis tends to progress in a high percentage of cases. The progression rate varies according to the age at diagnosis, with infantile scoliosis being the most unpredictable. There are many confounders, such as age, Risser sign and baseline Cobb angles that were not consistent among studies, making the data very heterogeneous.

A prospective and controlled comparative study. To verify the difference in morphologic appearance between a group of adolescents with progressive adolescent idiopathic scoliosis and a control group of normal adolescents. In a previous retrospective study, the possibility of a relation between progressive adolescent idiopathic scoliosis and specific morphotypes was demonstrated. Fifty-two adolescent girls with progressive adolescent idiopathic scoliosis were compared with an age-matched control group of 62 unaffected girls using a classification technique based on morphologic somatotypes. Morphotypes were evaluated with standardized pre-established criteria based on Sheldon's technique. Patients with progressive adolescent idiopathic scoliosis showed significantly less mesomorphism (mean value of 0.88 +/- 0.51) than control girls (mean value of 1.72 +/- 0.52). Adolescent girls with progressive adolescent idiopathic scoliosis have a morphologic somatotype that is different from the normal adolescent population. Subjects with progressive adolescent idiopathic scoliosis are significantly less mesomorphic than control girls. This observation may be of value as a predictive factor for early identification of subjects with adolescent idiopathic scoliosis at greater risk of progression.

Medium- to long-term retrospective evaluation of clinical and radiographic outcome in the treatment of degenerative lumbar diseases with hybrid posterior fixation. Thirty patients were included with the mean age of 47.8 years (range 35 to 60 years). All patients underwent posterior lumbar instrumentation using hybrid fixation for lumbar stenosis with instability (13 cases), degenerative spondylolisthesis Meyerding grade I (6 cases), degenerative disc disease of one or more adjacent levels in six cases and mild lumbar degenerative scoliosis in five patients. Clinical outcomes were evaluated using Oswestry disability index (ODI), Roland and Morris disability questionnaire (RMDQ), and the visual analog scale (VAS) pain scores. All patients were assessed by preoperative, postoperative and follow-up standing plain radiographs and lateral X-rays with flexion and extension. Adjacent disc degeneration was also evaluated by magnetic resonance imaging (MRI) at follow-up. At a mean follow-up of 6.1 years, we observed on X-rays and/or MRI 3 cases of adjacent segment disease (10.0 %): two of them (6.6 %) presented symptoms and recurred a new surgery. The last patient (3.3 %) developed asymptomatic retrolisthesis of L3 not requiring revision surgery. The mean preoperative ODI score was 67.6, RMDQ score was 15.1, VAS back pain score was 9.5, and VAS leg pain score was 8.6. Postoperatively, these values improved to 28.1, 5.4, 3.1, and 2.9, respectively, and remained substantially unchanged at the final follow-up: (27.7, 5.2, 2.9, and 2.7, respectively). After 5-year follow-up, hybrid posterior lumbar fixation presented satisfying clinical outcomes in the treatment of degenerative disease.

A systematic review on the effectiveness and cost-effectiveness of school scoliosis screening programme was carried out. A total of 248 relevant titles were identified, 117 abstracts were screened and 28 articles were included in the results. There was fair level of evidence to suggest that school scoliosis screening programme is safe, contributed to early detection and reduction of surgery. There was also evidence to suggest that school-based scoliosis screening programme is cost-effective. Based on the above review, screening for scoliosis among school children is recommended only for high risk group such as girls at twelve years of age.

A multicenter study examining the association between radiographic and outcomes measures in adolescent idiopathic scoliosis. To evaluate the association between an objective radiographic scoring system and patient quality of life measures as determined by the Scoliosis Research Society outcomes instrument. Although surgical correction of scoliosis has been reported to be positively correlated with patient outcomes, studies to date have been unable to demonstrate an association between radiographic measures of deformity and outcomes measures in patients with adolescent idiopathic scoliosis. A standardized radiographic deformity scoring system and the Scoliosis Research Society outcome tool were used prospectively in seven scoliosis centers to collect data on patients with adolescent idiopathic scoliosis. A total of 354 data points for 265 patients consisting of those with nonoperative or preoperative curves >or=10 degrees, as well as those with surgically treated curves, were analyzed. Correlation analysis was performed to identify significant relationships between any of the radiographic measures, the Harms Study Group radiographic deformity scores (total, sagittal, coronal), and the seven Scoliosis Research Society outcome domains (Total Pain, General Self-Image, General Function, Activity, Postoperative Self-Image, Postoperative Function, and Satisfaction) as well as Scoliosis Research Society outcomes instrument total scores. Radiographic measures that were identified as significantly correlated with Scoliosis Research Society outcome scores were then entered into a stepwise regression analysis. The coronal measures of thoracic curve and lumbar curve magnitude were found to be significantly correlated with the Total Pain, General Self-Image, and total Scoliosis Research Society scores (P < 0.0001). The thoracic and upper thoracic curve magnitudes were also correlated with General Function (P < 0.002). The "coronal" subscore as well as the "total" score of the

Scoliosis is associated with pectus excavatum. However, the change in the degree of scoliosis after pectus excavatum correction has not been clarified. This study examined how the correction of pectus excavatum influences the status of pre-existing scoliosis. A total of 779 pectus excavatum patients operated between 2007 and 2011 using the pectus bar were retrospectively analysed. Preoperative severity and postoperative change of scoliosis in accordance with the severity of pectus excavatum were evaluated. Cobb angle, Haller index and sternal tilt degree were measured from pre- and postoperative whole-spine anteroposterior radiographs and chest computed tomography. Sixty-three (8%) patients had scoliosis (Cobb angle >10°). No significant correlation was noted between postoperative changes in Cobb angle, Haller index or sternal tilt angle. Preoperative severity of scoliosis showed a positive correlation with postoperative changes in Cobb angle ( r  = 0.527, P  < 0.001). In analyses between groups with mild and moderate scoliosis (Cobb angle <15° and >15°, respectively), the mean postoperative Cobb angle was decreased in mild scoliosis (-2.88°) but was increased in moderate scoliosis (3.86°; P  < 0.001). Regarding the 'improvement' and 'aggravation' of scoliosis after pectus correction, preoperative severity of scoliosis was the only significant factor in univariable and multivariable analysis. Pectus excavatum repair using a pectus bar may improve scoliosis, but when the preoperative Cobb angle exceeds 15°, scoliosis may be aggravated. Therefore, pectus excavatum with concomitant moderate scoliosis requires extra caution during repair. This preliminary result suggests further investigation into the effect of chest cage remodelling on spine dynamics. © The Author 2017.

Pre-existing cognitive impairment (CI) is emerging as a predictor of poor post-operative outcomes in elderly patients. Little is known about impaired preoperative cognition and outcomes after elective spine surgery in this patient population. The purpose of this study was to assess the prevalence of neuro CI in elderly patients undergoing deformity surgery and its impact on postoperative outcomes. Elderly subjects undergoing elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Pre-operative baseline cognition was assessed using the Saint Louis Mental Status (SLUMS) test. SLUMS consists of 11 questions, which can give a maximum of 30 points. Mild CI was defined as a SLUMS score between 21-26 points, while severe CI was defined as a SLUMS score of ≤20 points. Normal cognition was defined as a SLUMS score of ≥27 points. Complication rates, duration of hospital stay, and 30-day readmission rates were compared between patients with and without baseline CI. Eighty-two subjects were included in this study, with mean age of 73.26±6.08 years. Fifty-seven patients (70%) had impaired cognition at baseline. The impaired cognition group had the following outcomes: increased incidence of one or more postoperative complications (39% vs. 20%), higher incidence of delirium (20% vs. 8%), and higher rate of discharge institutionalization at skilled nursing or acute rehab facilities (54% vs. 30%). The length of hospital stay and 30-day hospital readmission rates were similar between both cohorts (5.33 vs. 5.48 days and 12.28% vs. 12%, respectively). CI is highly prevalent in elderly patients undergoing surgery for adult degenerative scoliosis. Impaired cognition before surgery was associated with higher rates of post-operative delirium, complications, and discharge institutionalization. CI assessments should be considered in the pre-operative evaluations of elderly patients prior to surgery.

Various factors are reported to affect the spinal alignment in degenerative lumbar scoliosis (DLS). Although trunk muscles also appear to affect spinal alignment, the role of the trunk muscles is not yet clear. The aim was to elucidate the role of the multifidus (MF) and psoas (PS) in maintaining global spinal alignment in patients with DLS. This was a multicenter retrospective matched cohort study. Surgically treated 60 paired DLS and lumbar spinal stenosis (LSS) female (120 patients), matched for age and body mass index (BMI; DLS age 68.0±6.8 vs. LSS 67.1±8.9 years; BMI 21.6±3.3 vs. 23.2±3.8 kg/m(2)), were included and were followed for at least 2 years. Spinal alignment, muscle area, and volume were measured from radiographs, magnetic resonance images (MRIs), and whole-body dual-energy X-ray absorptiometry (DXA) scans. Muscle strength was measured by grip power and peak expiratory flow (PEF). As a surrogate of muscle area, we obtained the cross-sectional area (CSA) at the L5-S level from preoperative MRIs. The MF and PS CSAs were significantly smaller in the DLS group than in the LSS group (MF 477.7±192.5 vs. 779.8±248.6 mm(2), p<.01; PS 692.3±201.2 vs. 943.4±272.4 mm(2), p=.002), whereas percentage of difference between the right and left sides was significantly larger in the DLS group (MF 18.4±30.6 vs. 2.4±3.3%, p<.01; PS 14.4±15.8 vs. 2.1±2.2%, p<.01). In the extremities, there were no significant differences in the left- or right-side lean composition and grip strength or PEF tests between the groups. Correlation coefficient tests showed moderate correlations between the MF average CSA (avCSA) and global spinal alignment and spinopelvic alignment (pelvic incidence-lumbar lordosis; R=-0.37, -0.38) in the DLS group. The MF avCSA was correlated with the postoperative progression of kyphosis at the unfused thoracic vertebrae in the DLS group (R=0.34). The CSAs of the MF and PS were significantly smaller in the DLS group. Whole-body DXA showed no

Scoliosis is a common medical problem, with an incidence of between 0.47% and 5.2% in the general population globally. Adolescent idiopathic scoliosis (AIS) accounts for nearly 80% of all scoliosis. Young people with AIS often experience negative social consequences in association with their condition. Without proper and timely treatment, the potential resulting disabilities range from trunk deformity, pain, and neurological complications to compromised cardiopulmonary function, all of which may cause lifelong suffering. Scoliosis may be treated either conservatively or surgically, based on the severity of the disease. Bracing is the most widely adopted method of conservative treatment. However, the main goal of bracing is to inhibit the progression of the spinal curvature rather than to cure scoliosis. The clinical effectiveness of bracing in Taiwan has often been underutilized as a result of financial or other factors such as the availability of the treatment. The purpose of the present review is to clarify the effectiveness of bracing for AIS by elucidating the pathophysiology of scoliosis and examining the recent clinical evidence. The importance of preventative care and the unique contribution of nursing care to treatment has to date been under-recognized. The positive support that nurses provide to the families of the patients during the early phases of treatment as well as to the patients themselves, including helping them exercise appropriately and wear the brace correctly, is an essential component of effective treatment. Learning how to work with and to adapt to the brace being part of the body is an important part of the treatment as well as a way to avoid pain. Nurses are in an ideal position to facilitate this learning process and, overall, to provide health education.

Cerebral palsy (CP) is a group of nonprogressive syndromes of posture and motor impairment associated with lesions of the immature brain. Spastic quadriplegia is the most severe form with a high incidence of scoliosis, back pain, respiratory compromise, pelvic obliquity, and poor sitting balance. Surgical stabilization of the spine is an effective technique for correcting deformity and restoring sitting posture. The decision to operate in this group of patients is challenging. The aim of this study is to determine the benefits of surgical correction of scoliosis in children with spastic quadriplegia, the adverse effects of this treatment, and what preoperative factors affect patient outcome after surgical correction. A systematic review was undertaken to identify studies describing benefits and adverse effects of surgery in spastic quadriplegia. Factors affecting patient outcome following surgical correction of scoliosis were assessed. Studies involving adults and nonspastic quadriplegia were excluded. A total of 10 case series and 1 prospective and 3 retrospective cohort studies met inclusion criteria. There was significant variation in the overall risk of complications (range, 10.9-70.9%), mortality (range, 2.8-19%), respiratory/pulmonary complications (range, 26.9-57.1%), and infection (range, 2.5-56.8%). Factors associated with a worse outcome were a significant degree of thoracic kyphosis, days in the intensive care unit, and poor nutritional status. Caregivers report a high degree of satisfaction with scoliosis surgery for children with spastic quadriplegia. There is limited evidence of preoperative factors that can predict patient outcome after scoliosis. There is a need for well-designed prospective studies of scoliosis surgery in spastic quadriplegia.

Radiologic, pathologic, and ancillary methods were used to determine the occurrence of degenerative joint disease involving multiple joints of immature and adult dogs. Animals were selected for the development of hip joint dysplasia and chronic degenerative joint disease. Of disease-prone dogs, 82% (45 of 55 dogs) had radiologic changes, indicative of hip dysplasia, by 1 year of age. At necropsy, more abnormal joints were identified than by radiographic examination. Among 92 dogs between 3 to 11 months of age that had joint abnormalities, 71% had hip joint involvement; 38%, shoulder joint involvement; 22%, stifle joint involvement; and 40% had multiple joint involvement. Polyarthritis was asymptomatic and unexpected. Radiographic examination of older dogs also revealed evidence of degenerative joint disease in many joints. Multiple joint involvement was substantiated at necropsy of young and mature dogs. A similar pattern of polyarticular osteoarthritis was revealed in a survey (computer search) of necropsy reports from medical case records of 100 adult and elderly dogs. Usually, the joint disease was an incidental observation, unrelated to the clinical disease or to the cause of death. The frequent occurrence of degenerative changes in several joints of dogs aged 6 months to 17 years indicated that osteoarthritis may be progressive in these joints and raises the possibility that systemic factors are involved in the disease process.

Scoliosis and dental occlusion: a review of the literature

Background Idiopathic scoliosis is a deformity without clear etiology. It is unclear wether there is an association between malocclusion and scoliosis. Several types of occlusion were described in subjects with scoliosis, mostly case-reports. Objectives The aim of this review was to evaluate the type of occluslins more prevalent in subjects with scoliosis Search strategy All randomised and controlled clinical trials identified from the Cochrane Oral Health Group Trials Register, a MEDLINE search using the Mesh term scoliosis, malocclusion, and relevant free text words, and the bibliographies of papers and review articles which reported the outcome of orthodontic treatment in subjects with scoliosis that were published as abstracts or papers between 1970 and 2010. Selection criteria All randomised and controlled clinical trials published as full papers or abstracts which reported quantitative data on the outcomes malocclusion in subjects with scoliosis. Data collection and analysis Data were extracted without blinding to the authors, age of patients or type of occlusion. Main results Using the search strategy eleven observational longitudinal studies were identified. No randomized clinical trials were recorded. Twenty-three cross-sectional studies were recorderd, and the others studies were reviews, editorials, case-reports, or opinions. The clinical trials were often not controlled and were about the cephalometric evaluation after treatment with the modified Milwuakee brace, followed by the orthodontic treatment of the class II relationship with a functional appliance. Clinical trials also included the study of the associations between scoliosis and unilateral crossbite, in children with asymmetry of the upper cervical spine. This association was also investigated in rats, pigs and rabbits in clinical trials. The other associations between scoliosis and occlusion seems to be based only on cross-sectional studies, case-reports, opinions. Authors' conclusions Based

Adolescent idiopathic scoliosis is one of the most common spinal deformities, yet its cause is unknown. Various theories look to biomechanical, neuromuscular, genetic, and environmental origins, yet our understanding of scoliosis etiology is still limited. Determining the cause of a disease is crucial to developing the most effective treatment. Associations made with scoliosis do not necessarily point to causality, and it is difficult to determine whether said associations are primary (playing a role in development) or secondary (develop as a result of scoliosis). Scoliosis is a complex condition with highly variable expression, even among family members, and likely has many causes. These causes could be similar among homogenous groups of AIS patients, or they could be individual. Here, we review the most prevalent theories of scoliosis etiology and recent trends in research.

Scoliosis can be considered as one of the classical orthopedic diseases of the spine. The history of orthopedics is closely connected to the development of the therapy of scoliosis. In the eighteenth and the beginning of the nineteenth centuries the therapy of scoliosis was mainly a conservative corrective orthopedic treatment with a variety of corset forms and extension bed treatment. In the middle of the nineteenth century physiotherapy (movement therapy) became established as an supplementary active treatment. The first operations for treatment of scoliosis were carried out in 1839. The real success with surgical procedures for improvement in corrective options was connected to the introduction of metal spinal implants in the early 1960s.

OBJECTIVE The authors aimed to provide an updated and consolidated report on the epidemiology, management, and functional outcome of cases of myelomeningocele (MMC) in patients with scoliosis. METHODS A comprehensive literature search was performed using MEDLINE, Embase, Google Scholar, and the Cochrane Database of Systematic Reviews on cases of MMC in patients with scoliosis between 1980 and 2016. The initial search yielded 670 reports. After removing duplicates and applying inclusion criteria, we included 32 full-text original articles in this study. RESULTS Pooled statistical analysis of the included articles revealed the prevalence of scoliosis in MMC patients to be 53% (95% CI 0.42-0.64). Slightly more females (56%) are affected with both MMC and scoliosis than males. Motor level appears to be a significant predictor of prevalence, but not severity, of scoliosis in MMC patients. Treatment options for these patients include tethered cord release (TCR) and fusion surgeries. Curvature improvement and stabilization after TCR may be limited to patients with milder (< 50°) curves. Meanwhile, more aggressive fusion procedures such as a combined anterior-posterior approach may result in more favorable long-term scoliosis correction, albeit with greater complication rates. Quality of life metrics including ambulatory status and sitting stability are influenced by motor level of the lesion as well as the degree of the scoliosis curvature. CONCLUSIONS Scoliosis is among the most common and challenging comorbidities from which patients with MMC suffer. Although important epidemiological and management trends are evident, larger, prospective studies are needed to discover ways to more accurately counsel and more optimally treat these patients.

In the United Kingdom, lower incidences of intraspinal abnormalities in patients with early onset idiopathic scoliosis have been observed than in studies in other countries. We aimed to determine the rates of these abnormalities in United Kingdom patients diagnosed with idiopathic scoliosis before the age of 11 years. This retrospective study of patients attending an urban scoliosis clinic identified 71 patients satisfying a criteria of: clinical diagnosis of idiopathic scoliosis; age of onset ten years and 11 months or less; MRI screening for intraspinal abnormalities. United Kingdom census data combined with patient referral data was used to calculate incidence. Mean age at diagnosis was six years with 39 right-sided and 32 left-sided curves. Four patients (5.6%) were found to have intraspinal abnormalities on MRI. These consisted of: two combined Arnold-Chiari type 1 malformations with syrinx; one syrinx with a low lying conus; and one isolated syrinx. Overall annual incidence of early onset idiopathic scoliosis was one out of 182 000 (0.0006%). This study reports the lowest rates to date of intraspinal anomalies in patients with early onset idiopathic scoliosis, adding to knowledge regarding current incidences of these abnormalities as well as any geographical variation in the nature of the disease.

The onset of "idiopathic" scoliosis is gradual. It goes unnoticed by parent and child alike. The problem is often not detected until the curvature has progressed. Severe scoliosis has serious long-term systemic, cosmetic and psychologic effects. School-based screening programs are very effective in reducing the number of operations required. These programs can be carried out by school nurses, physical education teachers and volunteers who are trained by a knowledgeable physician. Brace treatment is successful when scoliosis is detected only.

Optimal management of idiopathic scoliosis in adolescence

Idiopathic scoliosis is a three-dimensional deformity of the growing spine, affecting 2%–3% of adolescents. Although benign in the majority of patients, the natural course of the disease may result in significant disturbance of body morphology, reduced thoracic volume, impaired respiration, increased rates of back pain, and serious esthetic concerns. Risk of deterioration is highest during the pubertal growth spurt and increases the risk of pathologic spinal curvature, increasing angular value, trunk imbalance, and thoracic deformity. Early clinical detection of scoliosis relies on careful examination of trunk shape and is subject to screening programs in some regions. Treatment options are physiotherapy, corrective bracing, or surgery for mild, moderate, or severe scoliosis, respectively, with both the actual degree of deformity and prognosis being taken into account. Physiotherapy used in mild idiopathic scoliosis comprises general training of the trunk musculature and physical capacity, while specific physiotherapeutic techniques aim to address the spinal curvature itself, attempting to achieve self-correction with active trunk movements developed in a three-dimensional space by an instructed adolescent under visual and proprioceptive control. Moderate but progressive idiopathic scoliosis in skeletally immature adolescents can be successfully halted using a corrective brace which has to be worn full time for several months or until skeletal maturity, and is able to prevent more severe deformity and avoid the need for surgical treatment. Surgery is the treatment of choice for severe idiopathic scoliosis which is rapidly progressive, with early onset, late diagnosis, and neglected or failed conservative treatment. The psychologic impact of idiopathic scoliosis, a chronic disease occurring in the psychologically fragile period of adolescence, is important because of its body distorting character and the onerous treatment required, either conservative or surgical

Early-onset scoliosis: current treatment.

Early-onset scoliosis, which appears before the age of 10, can be due to congenital vertebral anomalies, neuromuscular diseases, scoliosis-associated syndromes, or idiopathic causes. It can have serious consequences for lung development and significantly reduce the life expectancy compared to adolescent scoliosis. Extended posterior fusion must be avoided to prevent the crankshaft phenomenon, uneven growth of the trunk and especially restrictive lung disease. Conservative (non-surgical) treatment is used first. If this fails, fusionless surgery can be performed to delay the final fusion procedure until the patient is older. The gold standard delaying surgical treatment is the implantation of growing rods as described by Moe and colleagues in the mid-1980s. These rods, which are lengthened during short surgical procedures at regular intervals, curb the scoliosis progression until the patient reaches an age where fusion can be performed. Knowledge of this technique and its complications has led to several mechanical improvements being made, namely use of rods that can be distracted magnetically on an outpatient basis, without the need for anesthesia. Devices based on the same principle have been designed that preferentially attach to the ribs to specifically address chest wall and spine dysplasia. The second category of surgical devices consists of rods used to guide spinal growth that do not require repeated surgical procedures. The third type of fusionless surgical treatment involves slowing the growth of the scoliosis convexity to help reduce the Cobb angle. The indications are constantly changing. Improvements in surgical techniques and greater surgeon experience may help to reduce the number of complications and make this lengthy treatment acceptable to patients and their family. Long-term effects of surgery on the Cobb angle have not been compared to those involving conservative "delaying" treatments. Because the latter has fewer complications associated with

Apart from the recommended specific physiotherapy, the treatment of idiopathic scoliosis (IS) also incorporates non-specific manual therapy (NMT). The aim of this paper is to assess the efficacy of NMT (manual therapy, chiropractic, osteopathy) used in the treatment of children and adolescents with IS. The study analysed systematic reviews (Analysis 1) and other recent scientific publications (Analysis 2). Analysis 1 encompassed papers on the use of NMT in patients with IS. Works concerning specific physiotherapy (SP) or bracing (B) and other types of scoliosis were excluded from the analysis. Inclusion criteria for Analysis 2 were: treatment with NMT; subjects aged 10-18 years with IS. The following types of papers were excluded: works analysing NMT combined with SP or B, reports concerning adult pa tients, analyses of single cases and publications included in Analysis 1. Analysis 1: six systematic reviews contained 6 papers on the efficacy of NMT in the treatment of IS. The results of these studies are contradictory, ranging from Cobb angle reduction to no treatment effects whatsoever. The papers analysed are characterised by poor methodological quality: small group sizes, incomplete descriptions of the study groups, no follow-up and no control groups. Analysis 2: in total, 217 papers were found. None of them met the criteria set for the analysis. 1. Few papers verifying the efficacy of manual therapy, chiropractic and osteopathy in the treatment of idiopathic scoliosis have been published to date. 2. The majority are experimental studies with poor methodology or observational case studies. 3. At present, the efficacy of non-specific manual therapy in the treatment of patients with idiopathic scoliosis cannot be reliably evaluated. 4. It is necessary to conduct further research based on appropriate methods (prospective, rando mi s ed, controlled studies) in order to reliably assess the usefulness of non-specific manual therapy in the treatment of idiopathic

Reduced SHOX gene expression has been demonstrated to be associated with all skeletal abnormalities in Turner syndrome, other than scoliosis (and kyphosis). There is evidence to suggest that Turner syndrome scoliosis is clinically and radiologically similar to idiopathic scoliosis, although the phenotypes are dissimilar. This pilot gene expression study used relative quantitative real-time PCR (qRT-PCR) of the SHOX (short stature on X) gene to determine whether it is expressed in vertebral body growth plates in idiopathic and congenital scoliosis. After vertebral growth plate dissection, tissue was examined histologically and RNA was extracted and its integrity was assessed using a Bio-Spec Mini, NanoDrop ND-1000 spectrophotometer and standard denaturing gel electrophoresis. Following cDNA synthesis, gene-specific optimization in a Corbett RotorGene 6000 real-time cycler was followed by qRT-PCR of vertebral tissue. Histological examination of vertebral samples confirmed that only growth plate was analyzed for gene expression. Cycling and melt curves were resolved in triplicate for all samples. SHOX abundance was demonstrated in congenital and idiopathic scoliosis vertebral body growth plates. SHOX expression was 11-fold greater in idiopathic compared to congenital (n = 3) scoliosis (p = 0.027). This study confirmed that SHOX was expressed in vertebral body growth plates, which implies that its expression may also be associated with the scoliosis (and kyphosis) of Turner syndrome. SHOX expression is reduced in Turner syndrome (short stature). In this study, increased SHOX expression was demonstrated in idiopathic scoliosis (tall stature) and congenital scoliosis.

What's New in Congenital Scoliosis?

Pahys, Joshua M; Guille, James T

2018-03-01

Congenital scoliosis is a failure of vertebral formation, segmentation, or a combination of the 2 arising from abnormal vertebral development during weeks 4 to 6 of gestation. The associated spinal deformity can be of varying severity and result in a stable or progressive deformity based on the type and location of the anomalous vertebra(e). Bracing for congenital scoliosis is rarely indicated, while recent reports have demonstrated the utility of serial derotational casting for longer curves with multiple anomalous vertebrae as an effective "time buying strategy" to delay the need for surgery. Earlier hemivertebra excision and short-segment posterior spinal fusion have been advocated to prevent future curve progression of the deformity and/or the development of large compensatory curves. It has been shown in recent long-term follow-up studies that growth rates of the vertebral body and spinal canal are not as dramatically affected by pedicle screw instrumentation at a young age as once thought. Growth friendly surgery with either spine-based or rib-based anchors has demonstrated good results with curve correction while maintaining spinal growth. Rib-based anchors are typically more commonly indicated in the setting of chest wall abnormalities and/or when spinal anatomy precludes placement of spinal instrumentation. Recently, magnetically controlled growing rods have shown promising results in several studies that include a small subset of congenital scoliosis cases. A literature search was performed to identify existing studies related to the treatment of congenital scoliosis published from January 1, 2005 to June 1, 2016. Databases included PubMed, Medline, and the Cochrane Library. The search was limited to English articles and yielded 36 papers.

Progressive adolescent idiopathic scoliosis (AIS) produces specific signs and symptoms, including trunk and spinal deformity and imbalance, impairment of breathing function, pain, progression during adult life, and psychological problems, as a whole resulting in an alteration of the health-related quality of life. A scoliosis-specific rehabilitation program attempts to prevent, improve, or minimize these signs and symptoms by using exercises and braces as the main tools in the rehabilitation treatment. Patient evaluation is an essential point in the decision-making process and determines the selection of the specific exercises and the specifications of the brace design. However, this article is not addressed to scoliosis management. In this present article, a complete definition and discussion of radiological aspects, such as the Cobb angle, axial rotation, curve pattern classifications, and sagittal configuration, follow a short description of the three-dimensional nature of AIS. The relationship between AIS and growth is also discussed. There is also a section dedicated to the assessment of trunk deformity and back asymmetry. Other important clinical aspects, such as pain and disability, changes in other regions of the body, muscular balance, breathing function, and health-related quality of life, are not discussed in this present article.

Trunk imbalance (ie, frontal trunk shift measured with a plumb line from C7 to S1) is part of the clinical evaluation in adolescent idiopathic scoliosis (AIS), but its prevalence and relationship with scoliosis, back pain, and health-related factors are not well documented. The principal objectives are to document trunk imbalance prevalence and to explore the association between trunk imbalance and the following factors: Cobb angle, type of scoliosis, back pain, function, mental health, and self-image. The secondary objective is to determine back pain prevalence and the relationship between back pain and each of the following: Cobb angle, function, mental health, and self-image. This is a cross-sectional study in a scoliosis clinic of a tertiary university hospital center. The sample includes youth with AIS (N=55). The outcome measures were trunk imbalance prevalence and magnitude, and back pain prevalence and intensity using the Numeric Pain Rating Scale (NPRS) and the Scoliosis Research Society-22 (SRS-22) pain score, and the function, self-image, and mental health domains of the SRS-22. Trunk imbalance and back pain were assessed in 55 patients with AIS (Cobb angle: 10-60°). Patients completed the SRS-22 questionnaire and the NPRS. Correlations were done between trunk imbalance and scoliosis (Cobb angle, type of scoliosis), back pain (NPRS and SRS-22 pain score), and health-related factors using Pearson correlation coefficients (r) and logistic regression models. Trunk imbalance prevalence is 85% and back pain prevalence is 73%. We found fair to moderate significant positive correlation between trunk imbalance and Cobb angle (r=0.32-0.66, p<.05) but not with back pain, function, mental health, self-image, or type of scoliosis. Lower self-reported pain significantly correlated with lower Cobb angles (r=0.29, p=.03), higher function (r=0.55, p=.000), higher self-image (r=0.44, p=.001), and better mental health (r=0.48, p=.000).

Usually, neuromuscular scolioses become clinically symptomatic relatively early and are rapidly progressive even after the end of growth. Without sufficient treatment they lead to a severe reduction of quality of life, to a loss of the ability of walking, standing or sitting as well as to an impairment of the cardiopulmonary system resulting in an increased mortality. Therefore, an intensive interdisciplinary treatment by physio- and ergotherapists, internists, pediatricians, orthotists, and orthopedists is indispensable. In contrast to idiopathic scoliosis the treatment of patients with neuromuscular scoliosis with orthosis is controversially discussed, whereas physiotherapy is established and essential to prevent contractures and to maintain the residual sensorimotor function.Frequently, the surgical treatment of the scoliosis is indicated. It should be noted that only long-segment posterior correction and fusion of the whole deformity leads to a significant improvement of the quality of life as well as to a prevention of a progression of the scoliosis and the development of junctional problems. The surgical intervention is usually performed before the end of growth. A prolonged delay of surgical intervention does not result in an increased height but only in a deformity progression and is therefore not justifiable. In early onset neuromuscular scolioses guided-growth implants are used to guarantee the adequat development. Because of the high complication rates, further optimization of these implant systems with regard to efficiency and safety have to be addressed in future research.

OBJECT Chiari malformation Type I (CM-I) is often found in patients with scoliosis. Most previous reports of CM-I and scoliosis have focused on patients with CM-I and a spinal syrinx. The relationship between CM-I and scoliosis in the absence of a syrinx has never been defined clearly. The authors sought to determine if there is an independent association between CM-I and scoliosis when controlling for syrinx status. METHODS The medical records of 14,118 consecutive patients aged ≤ 18 years who underwent brain or cervical spine MRI at a single institution in an 11-year span were reviewed to identify patients with CM-I, scoliosis, and/or syrinx. The relationship between CM-I and scoliosis was analyzed by using multivariate regression analysis and controlling for age, sex, CM-I status, and syrinx status. RESULTS In this cohort, 509 patients had CM-I, 1740 patients had scoliosis, and 243 patients had a spinal syrinx. The presence of CM-I, the presence of syrinx, older age, and female sex were each significantly associated with scoliosis in the univariate analysis. In the multivariate regression analysis, older age (OR 1.02 [95% CI 1.01-1.03]; p < 0.0001), female sex (OR 1.71 [95% CI 1.54-1.90]; p < 0.0001), and syrinx (OR 9.08 [95% CI 6.82-12.10]; p < 0.0001) were each independently associated with scoliosis. CM-I was not independently associated with scoliosis when controlling for these other variables (OR 0.99 [95% CI 0.79-1.29]; p = 0.9). CONCLUSIONS A syrinx was independently associated with scoliosis in a large pediatric population undergoing MRI. CM-I was not independently associated with scoliosis when controlling for age, sex, and syrinx status. Because CM-I is not independently associated with scoliosis, scoliosis should not necessarily be considered a symptom of low cerebellar tonsil position in patients without a syrinx.

Scoliosis, the most prevalent orthopaedic condition affecting children and adolescents, may have lasting physical, psychological and social consequences. With limited evidence-base, scoliosis-specific exercise therapies are an option. An overview of the subject and description of a long-term follow-up study including adults who in adolescence were treated with a scoliosis-specific exercise programme investigating the association of the exercise regime with present physical activity, physical functioning and subjective wellbeing. To the authors' best knowledge, this is the first long-term outcome study on scoliosis-specific exercises, in opposition to a number of studies in adults who were braced or treated surgically in adolescence. Observational, registry-based case-control study. Adult subjects who in adolescence were treated with an exercise programme or were under observation are invited. Spine and trunk deformity, respiratory function, physical capacity and trunk muscles' function are measured. Health-related quality of life with generic and condition-specific instruments, general mental health, depression and anxiety symptoms, disability due to low back problems and physical activity are assessed. The report is believed to provide the readers with an overview of this controversial aspect of rehabilitation, and that the proposed protocol will assist researchers designing their studies.

Gait in adolescent idiopathic scoliosis: energy cost analysis.

Mahaudens, P; Detrembleur, C; Mousny, M; Banse, X

2009-08-01

Walking is a very common activity for the human body. It is so common that the musculoskeletal and cardiovascular systems are optimized to have the minimum energetic cost at 4 km/h (spontaneous speed). A previous study showed that lumbar and thoracolumbar adolescent idiopathic scoliosis (AIS) patients exhibit a reduction of shoulder, pelvic, and hip frontal mobility during gait. A longer contraction duration of the spinal and pelvic muscles was also noted. The energetic cost (C) of walking is normally linked to the actual mechanical work muscles have to perform. This total mechanical work (W(tot)) can be divided in two parts: the work needed to move the shoulders and lower limbs relative to the center of mass of the body (COM(b)) is known as the internal work (W(int)), whereas additional work, known as external work (W(ext)), is needed to accelerate and lift up the COM(b) relative to the ground. Normally, the COM(b) goes up and down by 3 cm with every step. Pathological walking usually leads to an increase in W (tot) (often because of increased vertical displacement of the COM(b)), and consequently, it increases the energetic cost. The goal of this study is to investigate the effects of scoliosis and scoliosis severity on the mechanical work and energetic cost of walking. Fifty-four female subjects aged 12 to 17 were used in this study. Thirteen healthy girls were in the control group, 12 were in scoliosis group 1 (Cobb angle [Cb] < or = 20 degrees), 13 were in scoliosis group 2 (20 degrees < Cb < 40 degrees), and 16 were in scoliosis group 3 (Cb > or = 40 degrees). They were assessed by physical examination and gait analysis. The 41 scoliotic patients had an untreated progressive left thoracolumbar or lumbar AIS. During gait analysis, the subject was asked to walk on a treadmill at 4 km h(-1). Movements of the limbs were followed by six infrared cameras, which tracked markers fixed on the body. W(int) was calculated from the kinematics. The movements of the COM

In recent decades, there has been a call for change among all stakeholders involved in scoliosis management. Parents of children with scoliosis have complained about the so-called "wait and see" approach that far too many doctors use when evaluating children's scoliosis curves between 10° and 25°. Observation, Physiotherapy Scoliosis Specific Exercises (PSSE) and bracing for idiopathic scoliosis during growth are all therapeutic interventions accepted by the 2011 International Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT). The standard features of these interventions are: 1) 3-dimension self-correction; 2) Training activities of daily living (ADL); and 3) Stabilization of the corrected posture. PSSE is part of a scoliosis care model that includes scoliosis specific education, scoliosis specific physical therapy exercises, observation or surveillance, psychological support and intervention, bracing and surgery. The model is oriented to the patient. Diagnosis and patient evaluation is essential in this model looking at a patient-oriented decision according to clinical experience, scientific evidence and patient's preference. Thus, specific exercises are not considered as an alternative to bracing or surgery but as a therapeutic intervention, which can be used alone or in combination with bracing or surgery according to individual indication. In the PSSE model it is recommended that the physical therapist work as part of a multidisciplinary team including the orthopeadic doctor, the orthotist, and the mental health care provider - all are according to the SOSORT guidelines and Scoliosis Research Society (SRS) philosophy. From clinical experiences, PSSE can temporarily stabilize progressive scoliosis curves during the secondary period of progression, more than a year after passing the peak of growth. In non-progressive scoliosis, the regular practice of PSSE could produce a temporary and significant reduction of the Cobb angle. PSSE can also

To assess the quality of life using the SRS 22 test in patients with scoliosis of 20 or more degrees Cobb. A prospective descriptive study was conducted between April and May 2016 on patients with scoliosis of at least 20 degrees Cobb and aged between 10 and 20 years. A record was made of weight, height, body mass index, and the SR 22 specific quality of life questionnaire for patients with scoliosis was completed. Patients were divided into two groups for analysis: a) scoliosis between 20 and 29 degrees Cobb (n=44); and b) scoliosis with a Cobb of 30 degrees or greater (n=32). There were significant differences in the dimensions that assess pain, image self-perception, and satisfaction with treatment, being valued worse when the degree of scoliosis Cobb is 30 degrees or higher. There were no significant differences in function/activity or mental health. The overall score of the questionnaire was also worse in the group with the highest degree of scoliosis. The weight, height, and BMI showed no significant differences due to the varying degrees of scoliosis. Scoliosis significantly affects the quality of life of people who suffer it, and there is a negative correlation between the severity of scoliosis measured by degrees Cobb and quality of life.

Genetic engineering techniques were used to develop an animal model of juvenile scoliosis during a postnatal skeletal-growth stage. To investigate the effect of targeted SHP2 (Src homology-2) deficiency in chondrocytes on the development of scoliosis during a juvenile growth stage in mice. Juvenile idiopathic scoliosis can lead to progressive severe spinal deformity. The pathophysiology and molecular mechanisms responsible for the deformity are unknown. Here, we investigated the role of SHP2 deficiency in chondrocytes as a potential cause of juvenile scoliosis. Genetically engineered mice with inducible deletion of SHP2 in chondrocytes were generated. The SHP2 function in chondrocytes was inactivated during a juvenile growth stage from the mouse age of 4 weeks. Radiographical, micro-computed tomographic, and histological assessments were used to analyze spinal changes. When SHP2 deficiency was induced during the juvenile stage, a progressive kyphoscoliotic deformity (thoracic lordosis and thoracolumbar kyphoscoliosis) developed within 2 weeks of the initiation of SHP2 deficiency. The 3-dimensional micro-computed tomography analysis confirmed the kyphoscoliotic deformity with a rotational deformity of the spine and osteophyte formation. The histological analysis revealed disorganization of the vertebral growth plate cartilage. Interestingly, when SHP2 was disrupted during the adolescent to adult stages, no spinal deformity developed. SHP2 plays an important role in normal spine development during skeletal maturation. Chondrocyte-specific deletion of SHP2 at a juvenile stage produced a kyphoscoliotic deformity. This new mouse model will be useful for future investigations of the role of SHP2 deficiency in chondrocytes as a mechanism leading to the development of juvenile scoliosis. N/A.

Steinert syndrome is described as an autosomal dominant condition characterized by progressive muscular wasting, myotonia, musculoskeletal manifestations and rare spinal defects. Little is reported about spinal deformity associated with this syndrome. We present a patient with Steinert syndrome complicated by scoliosis. In the literature on muscular dystrophy, other than Duchenne, little mention is given to the problem of scoliosis in general and its treatment in particular. A case report of a patient with Steinert syndrome associated with thoracic scoliosis and hypokyphosis is presented. A 17-year-old boy presented with King type II right thoracic scoliosis (T5-T11, Cobb angle of 40 degrees) and hypokyphosis--10 degrees. He was treated with posterior stabilization and instrumentation at level T3-L2 with a postoperative correction of the scoliotic curve to 20 degrees. Histopathologic examination of the muscles confirmed the diagnosis of Steinert myotonic dystrophy. At 30-month follow-up, the patient was clinically pain free and well balanced. Plain radiographs showed solid spine fusion with no loss of deformity correction. Scoliosis in Steinert syndrome shares the characteristic of an arthrogrypotic neuromuscular curve and demands the extensive soft tissue release for optimal surgical correction. Intraoperative observations included profound tissue bleeding, abnormally tough soft tissues and a difficult recovery from anaesthesia.

OBJECTIVE Recently, minimally invasive scoliosis surgery (MISS) was introduced for the correction of adult scoliosis. Multiple benefits including a good deformity correction rate and fewer complications have been demonstrated. However, few studies have reported on the use of MISS for the management of adolescent idiopathic scoliosis (AIS). The purpose of this study was to investigate the outcome of posterior MISS assisted by O-arm navigation for the correction of Lenke Type 5C AIS. METHODS The authors searched a database for all patients with AIS who had been treated with either MISS or PSF between November 2012 and January 2014. Levels of fusion, density of implants, operation time, and estimated blood loss (EBL) were recorded. Coronal and sagittal parameters were evaluated before surgery, immediately after surgery, and at the last follow-up. The accuracy of pedicle screw placement was assessed according to postoperative axial CT images in both groups. The 22-item Scoliosis Research Society questionnaire (SRS-22) results and complications were collected during follow-up. RESULTS The authors retrospectively reviewed the records of 45 patients with Lenke Type 5C AIS, 15 who underwent posterior MISS under O-arm navigation and 30 who underwent posterior spinal fusion (PSF). The 2 treatment groups were matched in terms of baseline characteristics. Comparison of radiographic parameters revealed no obvious difference between the 2 groups immediately after surgery or at the final follow-up; however, the MISS patients had significantly less EBL (p < 0.001) and longer operation times (p = 0.002). The evaluation of pain and self-image using the SRS-22 showed significantly higher scores in the MISS group (p = 0.013 and 0.046, respectively) than in the PSF group. Postoperative CT showed high accuracy in pedicle placement in both groups. No deep wound infection, pseudarthrosis, additional surgery, implant failure, or neurological complications were recorded in either group

A retrospective clinical study of scoliosis-associated airflow obstruction due to endothoracic vertebral hump. The purpose of this study was to evaluate and present anatomical features of patients with scoliosis who showed airflow obstruction caused by endothoracic vertebral hump. It is well known that severe scoliosis causes airflow restriction due to thoracic cage deformity. There have been few reports of clinical data and anatomical features on scoliosis associated with airflow obstruction due to endothoracic vertebral hump. The subjects were 6 patients. The diagnoses were idiopathic scoliosis in 3 patients, symptomatic scoliosis in 2 patients, and thoracogenic scoliosis in 1 patient. The radiological outcome, comorbidities, pre- and postoperative respiratory function, and surgical complication were analyzed. Four patients had preoperative atelectasis on the convex side of the lower lobe and improved after the operations. All patients showed main thoracic curves and their apex was located at T7-T9. All patients had lordoscoliosis except 1, who demonstrated kyphosing scoliosis. The correction rate was 78% (62.8%-83.5%). Preoperative thoracic lordosis within the range of -5° to -47° was postoperatively corrected to a substantially normal kyphosis within the range of 9° to 24°. The average vital capacity, percent VC improved from 0.72 L (0.33-1.17 L) to 1.21 L (0.82-1.71 L) and 45.5% (37.3%- 50.8%) to 63.7% (41.0%-88.6%) relatively. Spine Penetration Index improved from 23% (18%-35%) to 16% (13%-19%). Endothoracic hump ratio improved from 1.34 (0.98-1.93) to 1.12 (0.86-1.28). Each patient with symptomatic scoliosis and thoracogenic scoliosis required relatively long periods of respiration management. Patients having lordoscoliosis with an apex located between T7 and T9 may develop airflow obstruction due to an endothoracic vertebral hump. Correction of lordoscoliosis through anterior and posterior approaches successfully improved endothoracic hump ratio and

Adolescent idiopathic scoliosis (AIS) is a progressive growth disease that affects spinal anatomy, mobility, and left-right trunk symmetry. Consequently, AIS can modify human locomotion. Very few studies have investigated a simple activity like walking in a cohort of well-defined untreated patients with scoliosis. The first goal of this study is to evaluate the effects of scoliosis and scoliosis severity on kinematic and electromyographic (EMG) gait variables compared to an able-bodied population. The second goal is to look for any asymmetry in these parameters during walking. Thirteen healthy girls and 41 females with untreated AIS, with left thoracolumbar or lumbar primary structural curves were assessed. AIS patients were divided into three clinical subgroups (group 1 < 20°, group 2 between 20 and 40°, and group 3 > 40°). Gait analysis included synchronous bilateral kinematic and EMG measurements. The subjects walked on a treadmill at 4 km/h (comfortable speed). The tridimensional (3D) shoulder, pelvis, and lower limb motions were measured using 22 reflective markers tracked by four infrared cameras. The EMG timing activity was measured using bipolar surface electrodes on quadratus lumborum, erector spinae, gluteus medius, rectus femoris, semitendinosus, tibialis anterior, and gastrocnemius muscles. Statistical comparisons (ANOVA) were performed across groups and sides for kinematic and EMG parameters. The step length was reduced in AIS compared to normal subjects (7% less). Frontal shoulder, pelvis, and hip motion and transversal hip motion were reduced in scoliosis patients (respectively, 21, 27, 28, and 22% less). The EMG recording during walking showed that the quadratus lumborum, erector spinae, gluteus medius, and semitendinosus muscles contracted during a longer part of the stride in scoliotic patients (46% of the stride) compared with normal subjects (35% of the stride). There was no significant difference between scoliosis groups 1, 2, and 3 for

The purpose of this study was to evaluate the management and outcomes of CDH patients with scoliosis. From January 1996 to August 2015, 26 of 380 (7%) CDH patients were diagnosed with scoliosis. Six (23%) were prenatally diagnosed by ultrasound, and 9 (35%) were diagnosed postnatally. The remaining 11 (42%) developed scoliosis after discharge. Mean follow-up was 6.6years. Among the 15 patients with congenital scoliosis, there were 2 (13%) perinatal deaths. Five of the 13 (38%) survivors required orthopedic surgery, and 2 have required bracing. The mean age at initial surgery was 7years. These five children underwent an average of 2.8 (range 1-7) expansions or revisions. All surgical patients required supplemental oxygen at 28days of life, and 1 required a tracheostomy. None of the 11 patients who developed scoliosis later in life required surgery, but 3 have required bracing. Six of the 11 (55%) required a patch repair for CDH compared to 158 of 264 (60%) CDH patients without scoliosis (p=0.73). Early diagnosis of scoliosis in CDH patients is associated with a high rate of surgery. There was not a higher incidence of patch repair among patients who developed scoliosis. Prognosis.

Purpose: To determine the risk factors for scoliosis in children treated for neuroblastoma. Methods and materials: From 1957 to 1997, 58 children with neuroblastoma were treated at one institution and have survived a minimum of 5 years. There were 35 boys and 23 girls with a median age of 6 months (range, 2 weeks to 15 years) at initial diagnosis. Primary site was located in the adrenal gland in 25 (43.1%), abdominal/nonadrenal in 16 (27.6%), thoracic in 12 (20.7%), cervical in 3 (5.3%), and pelvic region in 2 (3.5%). The International Neuroblastoma Staging System (INSS) stage was Stage 1 inmore » 10 (17.2%), Stage 2A in 7 (12.1%), Stage 2B in 5 (8.6%), Stage 3 in 22 (37.9%), Stage 4 in 4 (6.9%), and Stage 4S in 10 (17.2%). Thirty-three (56.9%) received chemotherapy whereas 5 (8.6%) had a laminectomy as part of the surgical procedure. Twenty-seven (46.6%) received radiotherapy (RT). Beam energy was 1.25 MV in 11 (41%), 250 kV in 10 (37%), 4 MV in 4 (15%), and 6-MV photons in 1 patient. One patient received 300 cGy in 1 fraction total skin RT using 6-MeV electrons. For the remaining patients, fraction size was 100 cGy in 6 (22%), 150-180 cGy in 11 (41%), 200 cGy in 4 (15%), and 250-300 cGy in 3. Three patients had total body irradiation at 333 cGy for 3 fractions. For all children who received RT, median total dose was 2000 cGy (range, 300-3900 cGy). Patients who were treated with RT had plain films of the irradiated area every 1 to 2 years until at least the age of puberty. Median follow-up was 10 years (range, 5-46 years). Results: The overall 5-, 10-, and 15-year scoliosis-free rates were 87.6%, 79.0%, and 76.0% respectively. Twelve (21%) developed scoliosis at a median time of 51 months (range, 8-137 months). The degree of scoliosis was mild ({<=}20 deg ) in 8 (67%). Four had scoliosis ranging from 30 deg to 66 deg ; 3 of these patients required surgical intervention, whereas 1 had an underlying Duchenne muscular dystrophy which manifested itself 8 years after

Idiopathic scoliosis, defined as a lateral curvature of the spine of above 10 degrees (Cobb angle), is seen in 2-3% of the growing age population, while curves above 20 degrees , requiring conservative treatment, are found in 0.3-0.5%. In our observation, both under-treatment of progressive curves and over-treatment of stable cases are common during conservative management of scoliosis. A model of therapeutic management is presented based on the experience of Polish clinicians specialising in the treatment of scoliosis as well as the effects of work of a panel of experts of SOSORT (Society on Scoliosis Orthopaedic and Rehabilitation Treatment). The model comprises the indications for conservative treatment according to age, curve type and size and Risser grading. The aetiology, classifications, usefulness of the Lonstein and Carlson factor of progression and other methods of determining the probability of scoliosis progression, as well as the psychological aspects of conservative management are presented. Based on the knowledge of the natural history of idiopathic scoliosis, factors of progression and on the SOSORT experts' opinion, guidelines are proposed for clinicians treating children and adolescents with idiopathic scoliosis, including the timing and course of brace treatment and the types of exercises. Uniform practical guidelines developed by experts may represent an essential step towards establishing standards of conservative scoliosis care in our country.

OBJECTIVE Postoperative complications are one of the most significant concerns in surgeries of the spine, especially in higher-risk cases such as neuromuscular scoliosis. Neuromuscular scoliosis is a classification of multiple diseases affecting the neuromotor system or musculature of patients leading to severe degrees of spinal deformation, disability, and comorbidity, all likely contributing to higher rates of postoperative complications. The objective of this study was to evaluate deformity correction of patients with neuromuscular scoliosis over a 12-year period (2004-2015) by looking at changes in postsurgical complications and management. METHODS The authors queried the Scoliosis Research Society (SRS) Morbidity and Mortality (M&M) database for neuromuscular scoliosis cases from 2004 to 2015. The SRS M&M database is an international database with thousands of self-reported cases by fellowship-trained surgeons. The database has previously been validated, but reorganization in 2008 created less-robust data sets from 2008 to 2011. Consequently, the majority of analysis in this report was performed using cohorts that bookend the 12-year period (2004-2007 and 2012-2015). Of the 312 individual fields recorded per patient, demographic analysis was completed for age, sex, diagnosis, and preoperative curvature. Analysis of complications included infection, bleeding, mortality, respiratory, neurological deficit, and management practices. RESULTS From 2004 to 2015, a total of 29,019 cases of neuromuscular scoliosis were reported with 1385 complications, equating to a 6.3% complication rate when excluding the less-robust data from 2008 to 2011. This study shows a 3.5-fold decrease in overall complication rates from 2004 to 2015. A closer look at complications shows a significant decrease in wound infections (superficial and deep), respiratory complications, and implant-associated complications. The overall complication rate decreased by approximately 10% from 2004

Scoliosis is the deviation in the normal vertical spine. Although there are numerous studies available about treatment approaches for scoliosis, the numbers of studies that talk about its etiology and pathology are limited. Aim of this study was to discuss the different types of scoliosis; its curves and etiological theories; and to note their implication on its treatment. We examined various electronic databases including Pub MED, Medline, Cinhal, Cochrane library and Google scholar using key words "scoliosis", "etiology", "pathology" and "conservative treatment". References of obtained articles were also examined for cross references. The search was limited to articles in English language. A total of 145 papers, about Prevalence, History, Symptoms, classification, Biomechanics, Pathogenesis, Kinematics and Treatment of scoliosis were identified to be relevant. To choose the appropriate treatment approach for scoliosis we need to understand its etiology and pathogenesis first. Early intervention with conservative treatment like physiotherapy and bracing can prevent surgery.

Scoliosis is a complex spinal three-dimensional malformation with complicated pathogenesis, often associated with complications as thoracic deformity and shoulder imbalance. Because the acquisition of specimen or animal models are difficult, the biomechanical study of scoliosis is limited. In recent years, along with the development of the computer technology, software and image, the technology of establishing a finite element model of human spine is maturing and it has been providing strong support for the research of pathogenesis of scoliosis, the design and application of brace, and the selection of surgical methods. The finite element model method is gradually becoming an important tool in the biomechanical study of scoliosis. Establishing a high quality finite element model is the basis of analysis and future study. However, the finite element modeling process can be complex and modeling methods are greatly varied. Choosing the appropriate modeling method according to research objectives has become researchers' primary task. In this paper, the author reviews the national and international literature in recent years and concludes the finite element modeling methods in scoliosis, including data acquisition, establishment of the geometric model, the material properties, parameters setting, the validity of the finite element model validation and so on.

To date etiology of adolescent idiopathic scoliosis appears complex and still remains unclear. A distorted body schema has been proposed to be a part of a sequence of pathological events in the development of adolescent idiopathic scoliosis. To investigate the awareness of trunk misalignment in adolescents with idiopathic scoliosis. Information about 44 adolescents with idiopathic scoliosis was collected as follows: age; sex; handedness; family history of scoliosis; back pain; sport practice; shoulder and waist line symmetry; leg length; dorsal kyphosis; back hump; rehabilitation; scoliotic curve; Risser sign. We evaluated awareness of trunk misalignment with a graphic table displaying pictures of progressively increasing scoliotic curves. Patients were asked to indicate which picture corresponded to their perceived own spinal alignment. Patients with thoracolumbar scoliosis overestimated their actual thoracic spine curve. Patients with thoracic-thoracolumbar scoliosis underestimated their actual thoracolumbar spine curve and overestimated their actual lumbar spine curve. Scoliotic curve > 15°, double curve, younger age, back pain, family history of scoliosis and lower Risser score related with a misperception of trunk alignment. Our results support the hypothesis that adolescents with idiopathic scoliosis have an altered corporeal awareness of their trunk alignment.

Nonsurgical Management of Adolescent Idiopathic Scoliosis.

Pediatric patient visits for spinal deformity are common. Most of these visits are for nonsurgical management of scoliosis, with approximately 600,000 visits for adolescent idiopathic scoliosis (AIS) annually. Appropriate management of scoliotic curves that do not meet surgical indication parameters is essential. Renewed enthusiasm for nonsurgical management of AIS (eg, bracing, physical therapy) exists in part because of the results of the Bracing in Adolescent Idiopathic Scoliosis Trial, which is the only randomized controlled trial available on the use of bracing for AIS. Bracing is appropriate for idiopathic curves between 20° and 40°, with successful control of these curves reported in >70% of patients. Patient adherence to the prescribed duration of wear is essential to maximize the effectiveness of the brace. The choice of brace type must be individualized according to the deformity and the patient's personality as well as the practice setting and brace availability.

Spinal deformities are common in patients with osteogenesis imperfecta, a heritable disorder that causes bone fragility. The purpose of this study was to describe the behavior of spinal curvature during growth in patients with osteogenesis imperfecta and establish its relationship to disease severity and medical treatment with bisphosphonates. The medical records and radiographs of 316 patients with osteogenesis imperfecta were retrospectively reviewed. The severity of osteogenesis imperfecta was classified with the modified Sillence classification. Serial curve measurements were recorded throughout the follow-up period for each patient with scoliosis. Regression analysis was used to determine the effect of disease severity (Sillence type), patient age, and bisphosphonate treatment on the progression of scoliosis as measured with the Cobb method. Of the 316 patients with osteogenesis imperfecta, 157 had associated scoliosis, a prevalence of 50%. Scoliosis prevalence (68%) and mean progression rate (6° per year) were the highest in the group of patients with the most severe osteogenesis imperfecta (modified Sillence type III). A group with intermediate osteogenesis imperfecta severity, modified Sillence type IV, demonstrated intermediate scoliosis values (54%, 4° per year). The patient group with the mildest form of osteogenesis imperfecta, modified Sillence type I, had the lowest scoliosis prevalence (39%) and rate of progression (1° per year). Early treatment-before the patient reached the age of six years-of type-III osteogenesis imperfecta with bisphosphonate therapy decreased the curve progression rate by 3.8° per year, which was a significant decrease. Bisphosphonate treatment had no demonstrated beneficial effect on curve behavior in patients with other types of osteogenesis imperfecta or in patients of older age. The prevalence of scoliosis in association with osteogenesis imperfecta is high. Progression rates of scoliosis in children with osteogenesis

Opinions differ in the international literature about the efficacy of conservative approaches to scoliosis treatment. Because this divergence of opinion corresponds to a great discrepancy in the standards applied to conservative treatment methods, it is not astonishing that the results of conservative treatment as described in the literature also differ. Scoliosis normally does not have such dramatic effects that immediate surgery would be indicated.Moreover, it is clear from the published literature that it is the functional and physiological impairments of scoliosis patients--including pain, torso deformity, psychological disturbance, and pulmonary dysfunction--which require therapeutic intervention. In Germany the triad of outpatient physiotherapy, intensive inpatient rehabilitation, and bracing has proven effective in conservative scoliosis treatment.Indication, content, and results of the individual treatment procedures are described and discussed. The positive outcomes of this practice validate a policy of offering conservative scoliosis treatment as an alternative to patients, including those for whom surgery is indicated.

Early detection of progressive adolescent idiopathic scoliosis (AIS) was assessed based on 3D quantification of the deformity. Based on 3D quantitative description of scoliosis curves, the aim is to assess a specific phenotype that could be an early detectable severity index for progressive AIS. Early detection of progressive scoliosis is important for adapted treatment to limit progression. However, progression risk assessment is mainly based on the follow up, waiting for signs of rapid progression that generally occur during the growth peak. Sixty-five mild scoliosis (16 boys, 49 girls, Cobb Angle between 10 and 20°) with a Risser between 0 and 2 were followed from their first examination until a decision was made by the clinician, either considering the spine as stable at the end of growth (26 patients) or planning to brace because of progression (39 patients). Calibrated biplanar x-rays were performed and 3D reconstructions of the spine allowed calculating six local parameters related to main curve deformity. For progressive curve 3D phenotype assessment, data were compared with those previously assessed for 30 severe scoliosis (Cobb Angle > 35°), 17 scoliosis before brace (Cobb Angle > 29°) and 53 spines of nonscoliosis subjects. A predictive discriminant analysis was performed to assess similarity of mild scoliosis curves either to those of scoliosis or nonscoliosis spines, yielding a severity index (S-index). S-index value at first examination was compared with clinical outcome. At the first exam, 53 out of 65 predictions (82%) were in agreement with actual clinical outcome. Approximately, 89% of the curves that were predicted as progressive proved accurate. Although still requiring large scale validation, results are promising for early detection of progressive curves. 2.

While the association between scoliosis and cardiac and respiratory function impairments has been well characterized in clinical practice and research, the potential effect of scoliosis on urinary tract structure and renal function has received little attention. Therefore, the purpose of this study was to evaluate the preoperative clinical characteristics of urinary tract structure and renal function in pediatric patients with idiopathic scoliosis, using a combination of blood tests, urinalysis, and imaging. Preoperative measures of urinary tract structure and renal function were obtained for 16 patients, 13-17 years old, scheduled for corrective surgery for idiopathic scoliosis. Preoperative assessment included blood test and urinalysis, combined with structural imaging on ultrasound (US), magnetic resonance imaging (MRI), magnetic resonance urography (MRU), and radioisotope tracing (RI), using technetium-99 m mercaptoacetyltriglycine ( 99m Tc-MAG3). Differences in blood and urine tests between patients with and without urinary tract obstruction (UTO) were evaluated for significance using Mann-Whitney U test. For all 16 patients, blood tests and MRU were within normal limits. Dilatation of the renal pelvis was identified on US in eight patients (50.0%). UTO was identified on RI in six patients (37.5%). UTO was associated with elevated β2-microglobulin concentration. Urinary β2-microglobulin concentration >0.7 μg/mg Cr differentiated patients with UTO from those without UTO, with a sensitivity of 100% and specificity of 70%. β2-Microglobulin concentration may be a useful marker to screen for asymptomatic UTO in patients with idiopathic scoliosis. © 2016 Japan Pediatric Society.

Scoliosis occurs in about 0.2-0.6% of the general population. In the majority of cases the cause of this entity remains mostly unidentified. The search for the causes covers almost all aspects of its possible origin. We collected and systematised the contemporary theories and concepts concerning the aetiology of adolescent idiopathic scoliosis. Genetic and hereditary factors are commonly accepted as possible causes; however, the identification of the single gene responsible for the development of this condition seems impossible, which suggests multifactorial mechanism of its formation. Dysfunctions of the nervous system are recognised risks related to the development of scoliosis, but they are classified as belonging to a separate aetiological category. Scoliosis develops at the quickest rate during the child's growth spurt, which prompted the research on the role of the growth hormone in scoliosis aetiology. Melatonin is another hormone that is studied as a possible factor involved in development of this entity. In cases of progressive scoliosis, increased activity of calmodulin-a protein that regulates the levels of calcium ions-has been observed. The scientists have characterised numerous qualitative and quantitative changes in the composition of the tissue of intervertebral discs, spinal ligaments and paraspinal muscles. Some of the theories, explaining the nature of this entity, presented in this review seem to have only a purely theoretical value; their proliferation only confirms the fact that the actual nature of this condition has not been unveiled yet, and suggests its multifactorial aetiology.

Scoliosis is a three-dimensional deformation of the spine with a lateral curvature or deviation greater than 10 degrees and associated with vertebral rotation. Many conservative treatments are available for adolescents with idiopathic scoliosis, but the evidence for their effectiveness is still questioned. The objective of this study was to define the effectiveness of braces and individual physiotherapy for the comprehensive treatment of idiopathic scoliosis in adolescents. A retrospective study of 57 children with idiopathic thoracic dextroscoliosis with the magnitude of the thoracic curve between 20 degrees-35 degrees, treated in Orthopedic and Physiatrist Clinic as well as National Ortho-prosthetic Center within University Clinical Center of Kosova in Prishtina, during the period of 2003-2006. Inclusion of kinesitherapy in the comprehensive management of idiopathic scoliosis varied in the improvement of the muscle strength (satisfied and moderate) in almost 80% of the children while the correction of the curve was small in approximately 42.1% of cases. For children with idiopathic scoliosis, who require braces, an exercise program helps chest mobility, muscle strength, proper breathing flexibility in the spine, correct posture and keeps muscles in tone so that the transition period after brace removal is easier.

Examination of 1326 children and adolescents revealed physiological asymmetry of neuro-orthopedic status in 57% of the subjects, functional scoliosis in 33%, and structural scoliosis in 4.5%. Only 5.5% of the examined children and adolescents did not show clinical and functional signs of spinal pathology. Treatment with mechanical vibrations (vibro-massage or "swing" therapy), pulsed extremely high frequency (EHF) waves and electrical current yielded good therapeutic effect in cases with idiopathic scoliosis. Specifically, it resulted in a diminished angle of curvature of the spine and improved muscular support of the spine.

There is no large population size study on school screening for scoliosis in Malaysia. This study is aimed to determine the prevalence rate and positive predictive value (PPV) of screening programme for adolescent idiopathic scoliosis. A total of 8966 voluntary school students aged 13-15 years old were recruited for scoliosis screening. Screening was done by measuring the angle of trunk rotation (ATR) on forward bending test (FBT) using a scoliometer. ATR of 5 degrees or more was considered positive. Positively screened students had standard radiographs done for measurement of the Cobb angle. Cobb angle of >10° was used to diagnose scoliosis. The percentage of radiological assessment referral, prevalence rate and PPV of scoliosis were then calculated. Percentage of radiological assessment referral (ATR >5°) was 4.2% (182/4381) for male and 5.0% (228/4585) for female. Only 38.0% of those with ATR >5° presented for further radiological assessment. The adjusted prevalence rate was 2.55% for Cobb angle >10°, 0.59% for >20° and 0.12% for >40°. The PPV is 55.8% for Cobb angle >10°, 12.8% for >20° and 2.6% for > 40°. This is the largest study of school scoliosis screening in Malaysia. The prevalence rate of scoliosis was 2.55%. The positive predictive value was 55.8%, which is adequate to suggest that the school scoliosis screening programme did play a role in early detection of scoliosis. However, a cost effectiveness analysis will be needed to firmly determine its efficacy.

Observation and Early Intervention in Mild Idiopathic Scoliosis via Corrective Exercises in Growing Children.

PubMed

Sy, Ng

2016-01-01

Idiopathic scoliosis afflicts 2-3% of the population. For mild curvatures, observation is the treatment of choice. Though this passive "wait and see" approach has been used for many years, the practice is inconsistent among different countries. In Anglo-Saxon countries where scoliosis specific exercises are not practised, observation is indicated for curvatures below 25° in growing children and adolescents. In countries, such as France, Germany, Italy and Poland where scoliosis specific corrective exercises are employed, only patients with no signs of maturity and with curvatures below 15° are treated by observation. Patients with curvatures between 15 - 25° are treated by scoliosis specific exercises. In view of the unpredictability of the progression of scoliosis curvatures in immature patients and the lack of knowledge of long term biomechanical repercussions of mild idiopathic scoliosis on lumbar spine and lower extremities, it is proposed that active intervention through scoliosis specific exercises rather than passive observation be employed in the treatment of mild adolescent idiopathic scoliosis.

A prospective clinical study to test and adapt a Finnish version of the Scoliosis Research Society 30 (SRS-30) questionnaire. The aim of this study was to perform cross-cultural adaptation and evaluate the validity of the adapted Finnish version of the SRS-30 questionnaire. The SRS-30 questionnaire has proved to be a valid instrument in evaluating health-related quality of life (HRQoL) in adolescent and adult population with spine deformities in the United States. Multinational availability requires cross-cultural and linguistic adaptation and validation of the instrument. The SRS-30 was translated into Finnish using accepted methods for translation of quality-of-life questionnaires. A total of 274 adult patients with degenerative radiographic sagittal spinal disorder answered the questionnaire with sociodemographic data, RAND 36-item health survey questionnaire (RAND Corp. Health, Santa Monica, CA, US), Oswestry disability index, DEPS depression scale, and Visual Analog Scale (VAS) back and leg pain scales within 2 weeks' interval. The cohort included patients with and without previous spine surgery. Internal consistency and validity were tested with Cronbach α, intraclass correlation (ICC), standard error of measurement, and Spearman correlation coefficient with 95% confidence intervals (CIs). The internal consistency of SRS-30 was good in both surgery and nonsurgery groups, with Cronbach α 0.853 (95% CI, 0.670 to 0.960) and 0.885 (95% CI, 0.854 to 0.911), respectively. The test-retest reproducibility ICC of the SRS-30 total and subscore domains of patients with stable symptoms was 0.905 (95% CI, 0.870-0.930) and 0.904 (95% CI, 0.871-0.929), respectively. The questionnaire had discriminative validity in the pain, self-image, and satisfaction with management domains compared with other questionnaires. The SRS-30 questionnaire proved to be valid and applicable in evaluating HRQoL in Finnish adult spinal deformity patients. It has two domains related to deformity

Background The present study aimed to investigate the prevalence of scoliosis and to analyze the factors associated with scoliosis in schoolchildren aged between 7 and 17 years. Methods This is a cross-sectional and quantitative study with stratified random selection of public school students in the city of Santa Cruz, Brazil. The presence of scoliosis was examined, as well as the flexibility of the posterior muscle chain, socioeconomic characteristics, anthropometry, lifestyle habits, sexual maturation, and ergonomics of school furniture. In order to identify factors associated with scoliosis, the variables were divided in biological, socioeconomic, lifestyle, and ergonomic factors, and crude and adjusted prevalence ratios (PRs) were estimated by means of Poisson regression analysis. Results Two hundred and twelve pupils participated in this study (mean age 11.61 years, 58% female). The prevalence of scoliosis was 58.1% (n = 123) and associated with female sex (PR 2.54; 95% CI, 1.33–4.86) and age between 13 and 15 years (PR 5.35; 95% CI, 2.17–13.21). Sleeping in a hammock was inversely associated with scoliosis (PR 0.44; 95% CI, 0.23–0.81). Conclusions Scoliosis seems to be positively associated with female sex and age between 13 and 15 years, whereas the habit of sleeping in a hammock is negatively associated with the onset of scoliosis.

Osteogenesis imperfecta (OI) is a kind of heritable connective tissue disorder, including blue sclerae, hearing loss, skeletal dysplasia causing bone fragility and deformities. It is typically caused by collagen related gene mutations, which could lead to bone formation abnormalities. Scoliosis is one of the most common and severe spinal phenotype which has been reported in approximately 26–74.5% of all OI patients. Recent breakthroughs have suggested that OI can be divided into more than 16 types based on genetic mutations with different degrees of scoliosis. In this review, we summarize the etiology of scoliosis in OI, especially the genetic studies of different types. We aim to provide a systematic review of the genetic etiology and clinical suggestions of scoliosis in OI. PMID:29354746

Many practitioners, pediatricians, and general practitioners prescribe physical therapy when tracking scoliosis. However, has physical therapy alone proved its efficacy in the care of the scoliosis to slow down progression? Our purpose is to report the results of a literature review on the effectiveness of rehabilitation in idiopathic scoliosis. No current study presents sufficient scientific proof to validate the efficacy of isolated exercise therapy in scoliosis. Learned societies recognize, however, the efficacy of combining conservative therapy (brace+physiotherapy) in idiopathic scoliosis. Should we then still prescribe rehabilitation without brace treatment? Although physical therapy alone does not seem effective in treating scoliosis, it can limit potential painful phenomena and be beneficial for respiratory function. The physical therapist can also teach the teenager the classic principles of hygiene of the back. It may therefore be appropriate to prescribe physical therapy, but the principles and objectives must be explained to the patient and family in light of current evidence-based medicine.

2013-03-01

To review and summarize the current knowledge regarding the outcome measures used to evaluate scoliosis surgery. Literature review. Outcome instruments should be tested to ensure that they have adequate metric characteristics: content and construct validity, reliability, and responsiveness. In the evaluation of scoliosis, generic instruments to assess health-related quality of life (HRQL) have been used, such as the SF-36 questionnaire and the EuroQol5D instrument. Nonetheless, it is preferable to use disease-specific instruments for this purpose, such as the SRS-22 Patient Questionnaire and the quality of life profile for spinal deformities (QLPSD). More recently, these generic and disease-specific instruments have been complemented with the use of super-specific instruments; i.e., those assessing a single aspect of the condition or specific populations with the condition. The patients' perception of their trunk deformity and body image has received particular attention, and several instruments are available to evaluate these aspects, such as the Walter-Reed Visual Assessment Scale (WRVAS), the Spinal Appearance Questionnaire (SAQ), and the Trunk Appearance Perception Scale (TAPS). The impacts of brace use can also be measured with specific scales, including the Bad Sobernheim Stress Questionnaire (BSSQ) and the Brace Questionnaire (BrQ). The available instruments to evaluate the treatment for non-idiopathic scoliosis have not been sufficiently validated and analyzed. Evaluation of scoliosis treatment should include the patient's perspective, which can be obtained with the use of patient-reported outcome measures.

The purpose of this study was to compare the characteristics of scoliosis in Prader-Willi syndrome (PWS) patients versus idiopathic scoliosis (IS). We identified 193 PWS patients. Scoliosis was found in 58 PWS patients, 39 of whom were treated with GH. Fifty-five IS patients were consecutively selected from an outpatient clinic. We investigated 113 patients (58 PWS group, 55 IS group) followed for a minimum of 2 years. The mean age was 17.9 and 16.1 years, respectively. Deformity was measured using Lenke classification, Cobb angle, thoracic kyphosis at T2-5 and T5-12, lumbar lordosis at T12-S1, and sagittal alignment at the C7 plumb line. BMI was also recorded. According to the Lenke system, patients were classified as (PWS group/IS group): Type 1 (8/26), Type 2 (1/4), Type 3 (3/15), Type 4 (1/0), Type 5 (32/8), and Type 6 (13/2). The average Cobb angles were 32.6° in the PWS and 35.4° in the IS. No significant differences were found for the thoracic kyphosis (T2-5, T5-12), lumbar lordosis (T12-S1) or C7 plumb line between the two groups. BMI was increased in the PWS group not treated previously with GH as compared with the IS group and the PWS group with GH. Most PWS patients presented with lumbar or thoracolumbar curves (Type 5, 6), whereas IS patients typically had thoracic scoliosis (Type 1, 2, 3).

Biomechanical analysis of proximal junctional kyphosis (PJK) through numerical simulations. Assessment of the effect of sagittal alignment, the upper instrumented vertebral level (UIV), and 4 other surgical variables on biomechanical indices related to the PJK risks. Despite retrospective clinical studies, biomechanical analysis of individual parameters associated with PJK is lacking to support instrumentation strategies to reduce the PJK risks. Instrumentations of 6 adult scoliosis cases with different operative strategies were simulated (1,152 simulations). Proximal junctional (PJ) angle and flexion loads were evaluated against the sagittal alignment and the proximal instrumentation level. Instrumenting 1 more proximal vertebra allowed the PJ angle, proximal moment, and force to be reduced by 18%, 25%, and 16%, respectively. Shifting sagittal alignment by 20 mm posteriorly increased the PJ angle and proximal moment by 16% and 22%, and increased the equivalent posterior extensor force by 37%. Bilateral complete facetectomy, posterior ligaments resection, and the combination of the 2 resulted in an increase of the PJ angle (by 10%, 28%, and 53%, respectively), flexion forces (by 4%, 12%, and 22%, respectively), and proximal moments (by 16%, 44%, and 83%, respectively). Transverse process hooks at UIV compared with pedicle screws allowed 26% lower PJ angle and flexion loads. The use of proximal transition rods with proximal diameter reduced from 5.5 to 4 mm slightly reduced PJ angle, flexion force, and moment (less than 8%). The increase in sagittal rod curvature from 10° to 40° increased the PJ angle (from 6% to 19%), flexion force (from 3% to 10%), and moment (from 9% to 27%). Simulated posteriorly shifted sagittal alignment was associated with higher PJK risks, whereas extending instrumentation proximally allowed a lower mechanical risk of PJK. Preserving PJ intervertebral elements and using a more flexible anchorage at UIV help reduce the biomechanical risks

BACKGROUND Congenital scoliosis is a common type of vertebral malformation. Genetic susceptibility has been implicated in congenital scoliosis. METHODS We evaluated 161 Han Chinese persons with sporadic congenital scoliosis, 166 Han Chinese controls, and 2 pedigrees, family members of which had a 16p11.2 deletion, using comparative genomic hybridization, quantitative polymerase-chain-reaction analysis, and DNA sequencing. We carried out tests of replication using an additional series of 76 Han Chinese persons with congenital scoliosis and a multi-center series of 42 persons with 16p11.2 deletions. RESULTS We identified a total of 17 heterozygous TBX6 null mutations in the 161 persons with sporadic congenital scoliosis (11%); we did not observe any null mutations in TBX6 in 166 controls (P<3.8×10−6). These null alleles include copy-number variants (12 instances of a 16p11.2 deletion affecting TBX6) and single-nucleotide variants (1 nonsense and 4 frame-shift mutations). However, the discordant intrafamilial phenotypes of 16p11.2 deletion carriers suggest that heterozygous TBX6 null mutation is insufficient to cause congenital scoliosis. We went on to identify a common TBX6 haplotype as the second risk allele in all 17 carriers of TBX6 null mutations (P<1.1×10−6). Replication studies involving additional persons with congenital scoliosis who carried a deletion affecting TBX6 confirmed this compound inheritance model. In vitro functional assays suggested that the risk haplotype is a hypomorphic allele. Hemivertebrae are characteristic of TBX6-associated congenital scoliosis. CONCLUSIONS Compound inheritance of a rare null mutation and a hypomorphic allele of TBX6 accounted for up to 11% of congenital scoliosis cases in the series that we analyzed. PMID:25564734

A new method for nonradiographic evaluation of scoliosis was independently compared with the Cobb radiographic method, for the quantification of scoliotic curvature. To develop a protocol for computerized photogrammetry, as a nonradiographic method, for the quantification of scoliosis, and to mathematically relate this proposed method with the Cobb radiographic method. Repeated exposure to radiation of children can be harmful to their health. Nevertheless, no nonradiographic method until now proposed has gained popularity as a routine method for evaluation, mainly due to a low correspondence to the Cobb radiographic method. Patients undergoing standing posteroanterior full-length spine radiographs, who were willing to participate in this study, were submitted to dorsal digital photography in the orthostatic position with special surface markers over the spinous process, specifically the vertebrae C7 to L5. The radiographic and photographic images were sent separately for independent analysis to two examiners, trained in quantification of scoliosis for the types of images received. The scoliosis curvature angles obtained through computerized photogrammetry (the new method) were compared to those obtained through the Cobb radiographic method. Sixteen individuals were evaluated (14 female and 2 male). All presented idiopathic scoliosis, and were between 21.4 ± 6.1 years of age; 52.9 ± 5.8 kg in weight; 1.63 ± 0.05 m in height, with a body mass index of 19.8 ± 0.2. There was no statistically significant difference between the scoliosis angle measurements obtained in the comparative analysis of both methods, and a mathematical relationship was formulated between both methods. The preliminary results presented demonstrate equivalence between the two methods. More studies are needed to firmly assess the potential of this new method as a coadjuvant tool in the routine following of scoliosis treatment.

Scoliosis surgery is one of the most difficult orthopedic surgery that have been committed today as the failure rate of orthopedic surgery for adult patients is 15%. Aside from the long duration of surgery, this surgical failure is caused by failure in biomedical instrumentation. Furthermore, this kind of failure is causing inefficiency of the surgery. With current known orthopedic surgery method, three surgeons are needed in a single orthopedic surgery. In fact, a single surgery can take up to 8 hours to be done, which increases the risk of surgical failure. Based on this problem, authors hope that our orthopedic jacks could solve the problem.

There has been an increasing popularity of searching health related information online in recent years. Despite that considerable amount of scoliosis patients have shown interest in obtaining scoliosis information through Internet, previous studies have demonstrated poor quality of online information. However, this conclusion may vary depending on region and culture. Since China has a restricted Internet access outside of its borders, the aim of this study is to evaluate the quality of scoliosis information available online using recognized scoring systems and to analyze the Internet as a source of health information in China. A survey-based questionnaire was distributed to 280 respondents at outpatient clinics. Information on demographics and Internet use was collected. Binary logistic analysis was performed to identify possible predictors for the use of Internet. In addition, the top 60 scoliosis related websites assessed through 4 search engines were reviewed by a surgeon and the quality of online information was evaluated using DISCERN score and JAMA benchmark. Use of the Internet as a source for scoliosis related information was confirmed in 87.8% of the respondents. College education, Internet access at home and urban residence were identified as potential predictors for Internet use. However, the quality of online scoliosis related information was poor with an average DISCERN score of 27.9±11.7 and may be misleading for scoliosis patients. The study outlines the profile of scoliosis patients who use the Internet as a source of health information. It was shown that 87.8% of the scoliosis patients in outpatient clinics have searched for scoliosis related information on Internet. Urban patients, higher education and Internet access at home were identified as potential predictors for Internet search. However, the overall quality of online scoliosis related information was poor and confusing. Physician based websites seemed to contain more reliable information.

OBJECTIVE Postoperative delirium is common in elderly patients undergoing spine surgery and is associated with a longer and more costly hospital course, functional decline, postoperative institutionalization, and higher likelihood of death within 6 months of discharge. Preoperative cognitive impairment may be a risk factor for the development of postoperative delirium. The aim of this study was to investigate the relationship between baseline cognitive impairment and postoperative delirium in geriatric patients undergoing surgery for degenerative scoliosis. METHODS Elderly patients 65 years and older undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Preoperative cognition was assessed using the validated Saint Louis University Mental Status (SLUMS) examination. SLUMS comprises 11 questions, with a maximum score of 30 points. Mild cognitive impairment was defined as a SLUMS score between 21 and 26 points, while severe cognitive impairment was defined as a SLUMS score of ≤ 20 points. Normal cognition was defined as a SLUMS score of ≥ 27 points. Delirium was assessed daily using the Confusion Assessment Method (CAM) and rated as absent or present on the basis of CAM. The incidence of delirium was compared in patients with and without baseline cognitive impairment. RESULTS Twenty-two patients (18%) developed delirium postoperatively. Baseline demographics, including age, sex, comorbidities, and perioperative variables, were similar in patients with and without delirium. The length of in-hospital stay (mean 5.33 days vs 5.48 days) and 30-day hospital readmission rates (12.28% vs 12%) were similar between patients with and without delirium, respectively. Patients with preoperative cognitive impairment (i.e., a lower SLUMS score) had a higher incidence of postoperative delirium. One- and 2-year patient reported outcomes scores were similar in patients with and without delirium. CONCLUSIONS

Computational analysis using the finite-element method was used to examine a possible etiology of idiopathic scoliosis. To compare changes in the coronal and the transverse planes of idiopathic thoracic scoliosis with changes produced in a finite-element buckling model, and to investigate the influence of bone modeling on the buckling spine. Although it is now widely accepted that growth is related strongly to the onset and progression of scoliosis, the pathomechanism or etiology of idiopathic scoliosis still is not clear. A previous study showed that a buckling phenomenon caused by anterior spinal overgrowth can produce scoliosis, and that the fourth buckling mode matched the clinical characteristics associated with the thoracic type of idiopathic scoliosis. The fourth buckling mode occurs when the first, second, and third buckling modes are prevented. The spinal finite-element model used in this study consisted of 68,582 elements and 84,603 nodes. The transverse changes seen in the computed tomography images of 41 patients with idiopathic thoracic scoliosis (apex, T8; average Cobb angle, 52.5 degrees) were compared with those produced in the fourth buckling mode. Bone modeling (bone formation and resorption) was simulated as heat deformation caused by changes in temperature. The bone formation and resorption were simulated, respectively, by positive and negative volume changes in proportion to the stress that occurred in the buckling spine. Computed tomography images of scoliosis show that as the scoliosis becomes more severe, the thoracic cage decreases on the convex side of the curve and increases on the concave side. The opposite thoracic cage deformation was obtained in the fourth buckling mode. In patients with scoliosis, the sternum essentially remains in its original position with respect to the vertebrae, but in the linear buckling model, it shifted in the direction of vertebral body rotation. In contrast to clinical data, the incremental deformation

A hypothesis that the thoracic idiopathic scoliosis is buckling phenomenon of the fourth mode induced by the growth of thoracic vertebral bodies was presented in the previous work by the authors using numerical simulations with finite element model of the spine. If the hypothesis is acceptable, sensitivity function with respect to the critical growth of thoracic vertebrae on the maximization problem of buckling load with the fourth buckling mode gives us useful information to improve and develop treatments for the idiopathic scoliosis. The numerical results analyzed by the finite element method demonstrated that the sensitivity function is high at the articular capsules of the intervertebral joints, the intervertebral disks, the costotransverse joints and the constovertebral joints around the apex of the curvature in the case of the thoracic idiopathic scoliosis.

Using computerized spinal analysis, a new top view was developed that displays the spine as if the observer were above and looking down on the patient. Serial top views were obtained of 12 patients with idiopathic scoliosis. In five patients with clinically stable curves, the top views showed no change. One patient with an enlaring rib hump was seen on the top view to have progressive kyphosis but stable scoliosis. Six patients with progressive scoliosis all demonstrated collapse of the thoracic curve in the anteroposterior direction. Five of these six patients had associated lumbar curves. Three lumbar curves demonstrated collapsemore » in the anteroposterior direction similar to the collapse of the thoracic curves, and the other two curves appeared elongated in the anteroposterior direction.« less

The aim of this study was to identify the prevalence of proximal junctional kyphosis (PJK) in degenerative lumbar scoliosis (DLS) following long instrumented posterior spinal fusion, and to search for predictable risk factors for the progression of junctional kyphosis.In total 98 DLS patients with a minimum 2-year follow-up were reviewed prospectively. According to the occurrence of PJK at the last follow-up, patients were divided into 2 groups: PJK group and non-PJK group. To investigate risk values for the progression of PJK, 3 categorized factors were analyzed statistically: patient characteristics-preoperative data of age, sex, body mass index (BMI), bone mineral density (BMD) were investigated; surgical variables-the most proximal and distal levels of the instrumentation, the number of instrumented levels; pre- and postoperative radiographic parameters include the scoliotic angle, sagittal vertical axis, thoracic kyphosis, thoracolumbar junctional angle, lumbar lordosis, pelvic incidence, pelvic tilt, and sacral slope.PJK was developed in 17 of 98 patients (17.3%) until to the final follow-up and were enrolled as the PJK group, and 81 patients without PJK at final follow-up were enrolled as the non-PJK group. There was no statistically significant difference between the 2 groups in age at operation (P = 0.900). The patient's sex was excluded in statistical analysis because of the predominance of female patients. There were statistically significant difference between the 2 groups in BMI ([25.5 ± 1.7] kg/m in the PJK group and [23.6 ± 1.9] kg/m in the non-PJK group, P < 0.001) and BMD ([-1.4 ± 0.8] g/cm in the PJK group and [-0.7 ± 0.3] g/cm in the non-PJK group, P < 0.001). No specific surgery-related variables were found to be associated with an increased risk of developing PJK, except when the most proximal instrumented vertebrae stopped at thoracolumbar junction (T11-L1).

An actuarial "survivorship" analysis. The aim of this study was to define the incidence and cause of surgical revision 5 years after scoliosis surgery. Data on contemporary revision surgery rates after idiopathic scoliosis surgery beyond the 2 years postoperatively in the adolescent and young adult population are limited. Patients enrolled in a prospective, multicenter, idiopathic scoliosis surgical registry from 1995 to 2009 were reviewed. Any spine reoperation was defined as a "terminal event." An actuarial survivorship analysis that adjusts for patients lost to follow-up was performed to determine cumulative survival. Time intervals were defined as 0 to <3 months, 3 months to <1 year, 1 to <2 years, 2 to <5 years, and 5 to 10 years. Registry data and radiographs were reviewed and five categories for reoperation assigned: 1) implant failure and/or pseudarthrosis, 2) implant misplacement and/or prominence, 3) wound complication and/or infection, 4) residual deformity and/or progression, and 5) other. One thousand four hundred thirty-five patients from 12 sites were included. The majority were female (80%), with major thoracic curves (76% Lenke 1-4), and average age of 15 ± 2 years (10-22) at surgery. Most had posterior spinal instrumentation and fusion (81%). At this time, 75 (5.2%) patients required reoperation. Twenty-two occurred within 3 months postop, 10 more before 1 year, 12 more before 2 years, another 20 by 5 years, and 10 more after 5 years. This corresponded to an actuarial cumulative survival of 98.3% at 3 months, 97.5% at 1 year, 96.6% at 2 years, 93.9% at 5 years, and 89.8% at the final interval (5-10 yrs). Revisions for scoliosis continue to occur well after 2 years with a 5-year survivorship of 93.9%. Reasons for reoperation are not uniformly distributed over time, with implant-related issues and infection the leading cause for early revision, while late infection was the most common cause after 2 years. Long-term follow-up of these

Case-control study. To determine whether serum metal ion levels and erythrocyte chromium levels in adolescents with stainless steel spinal instrumentation are elevated when compared with 2 control groups. Instrumented spinal arthrodesis is a common procedure to correct scoliosis. The long-term consequences of retained implants are unclear. Possible toxic effects related to raised metal ion levels have been reported in the literature. Thirty patients who underwent posterior spinal arthrodesis with stainless steel instrumentation for scoliosis (group 1) were included. Minimum postoperative duration was 3 years. Serum chromium, molybdenum, iron, and ferritin levels were measured. Participants with elevated above normal serum chromium levels (n = 11) also underwent erythrocyte chromium analysis. Comparisons were made with 2 control groups; 10 individuals with scoliosis with no spinal surgery (group 2) and 10 volunteers without scoliosis (group 3). All control group participants underwent serum and erythrocyte analysis. Elevated above normal serum chromium levels were demonstrated in 11 of 30 (37%) group 1 participants. Elevated serum chromium levels were demonstrated in 0 of 10 participants (0%) in group 2 and 1 of 10 (10%) in group 3. There was a statistically significant elevation in serum chromium levels between group 1 and group 2 participants (P = 0.001). There was no significant association between groups 1, 2, and 3 for serum molybdenum, iron, and ferritin levels. Erythrocyte chromium measurements were considered within the normal range for all participants tested (n = 31). Raised serum chromium levels were detected in 37% of patients following instrumented spinal arthrodesis for correction of scoliosis. This new finding has relatively unknown health implications but potential mutagenic, teratogenic and carcinogenic sequelae. This is especially concerning with most scoliosis patients being adolescent females with their reproductive years ahead.

Attitudes regarding non-operative treatment for adolescent idiopathic scoliosis (AIS) may be changing with the publication of BRAiST. Physiotherapeutic Scoliosis Specific Exercises (PSSE) are used to treat AIS, but high-quality evidence is limited. The purpose of this study is to assess the attitudes of members of the Scoliosis Research Society towards PSSE. A survey was sent to all SRS members with questions on use of Physical Therapy (PT) and PSSE for AIS. The majority of the 263 respondents were from North America (175, 67 %), followed by Asia (37, 14 %) and Europe (36, 14 %). The majority of respondents (166, 63 %) prescribed neither PT nor PSSE, 28 (11 %) prescribed both PT and PSSE, 39 (15 %) prescribe PT only and 30 (11 %) prescribe PSSE only. PT was prescribed by 67 respondents, as an adjunct to bracing (39) and in small curves (32); with goals to improve aesthetics (27) and post-operative outcomes (25). Of the 196 who do not prescribe PT, the main reasons were lack of evidence (149) and the perception that PT had no value (112). PSSE was prescribed by 58 respondents. The most common indication was as an adjunct to bracing (49) or small curves (41); with goals to improve aesthetics (36), prevent curve progression (35) and improve quality of life (31). Of the respondents who do not prescribe PSSE, the main reasons were lack of supporting research (149), a perception that PSSE had no value (108), and lack of access (63). Most respondents state that evidence of efficacy may increase the role of PSSE, with 85 % (223 of 263) favoring funding PSSE studies by the SRS. The results show that 22 % of the respondents use PSSE for AIS, skepticism remains regarding the benefit of PSSE for AIS. Support for SRS funded research suggests belief that there is potential benefit from PSSE and the best way to assess that potential is through evidence development.

Prospective questionnaire administration study. To assess the ability to translate total and domain scores from Scoliosis Research Society (SRS)-24 to SRS-22r in a surgical-range, medical/interventional adolescent idiopathic scoliosis (AIS) patient population. Conversion of SRS-24 to SRS-22r is demonstrated in an operative cohort of patients with AIS, but not in a medical/interventional patient population. We simultaneously administered SRS-24 and SRS-22r questionnaires to 75 surgical-range, medical/interventional AIS patients and compared them. We performed analysis by regression modeling to produce conversion equations from SRS-24 to SRS-22r. The total SRS-24 score for these medical/interventional AIS patients was 92.5 ± 9.45 (mean, 3.9 ± 0.39), and the total SRS-22r score was 93.5 ± 9.63 (mean, 4.3 ± 0.44). The correlation between these 2 groups was fair (R 2 = 0.77) and improved to good when mental health or recall questions were removed. The correlation was also fair for total pain domains (R 2 = 0.73). However, there was poor correlation for general self-image (R 2 = 0.6) and unacceptable for post-treatment self-image (R 2 = 0.01), general function (R 2 = 0.52), activity function (R 2 = 0.56), and satisfaction (R 2 = 0.53). Compared with a published population of operative AIS patients, R 2 values for total SRS-24 scores, pain, general self-image, activity function, and satisfaction were similar (p > .05). The R 2 values for general function and combined general and activity function were significantly different between the operative and medical/interventional cohorts. Scoliosis Research Society-24 can be converted to SRS-22r scores with fair accuracy in the surgical-range, medical/interventional AIS patient population for total score, and total pain domains. The SRS-24 translates unacceptably to the SRS-22r in self-image, function, and satisfaction domains. The SRS-24 to SRS-22r conversion equations are similar to operative AIS patients, except for the

Acute pancreatitis is a possible complication after scoliosis surgery. Although some risk factors have been documented in the literature, clinical description of pancreatitis diagnosis and ensuing course still remain very poor. The aim of this study was to describe characteristics of acute pancreatitis after scoliosis surgery. A descriptive, retrospective and single-center study of fourteen adolescents with postoperative acute pancreatitis after spine fusion surgery in scoliosis management between April 2003 and August 2012 was performed. Acute pancreatitis occurred within 9.5 days (4-51) after surgery. Abdominal pain was atypical and was expressed in only half of the children. Ileus, nausea and vomiting were the most frequent signs. None of the acute pancreatitis cases was severe. Acute pancreatitis is an early complication of scoliosis surgery. Clinical signs are atypical and non-severe and can induce misleading forms. Presence of delayed digestive problems should alert the clinician to the risk of pancreatitis in the aftermath of scoliosis surgery.

This work identifies, among adolescents with idiopathic scoliosis, those demonstrating impaired sensorimotor control through a classification procedure comparing the amplitude of their vestibular-evoked postural responses. The sensorimotor control of healthy adolescents (n=17) and adolescents with idiopathic scoliosis (n=52) with either mild (Cobb angle≥15° and ≤30°) or severe (Cobb angle >30°) spine deformation was assessed through galvanic vestibular stimulation. A classification procedure sorted out adolescents with idiopathic scoliosis whether the amplitude of their vestibular-evoked postural response was dissimilar or similar to controls. Compared to controls, galvanic vestibular stimulation evoked larger postural response in adolescents with idiopathic scoliosis. Nonetheless, the classification procedure revealed that only 42.5% of all patients showed impaired sensorimotor control. Consequently, identifying patients with sensorimotor control impairment would allow to apply personalized treatments, help clinicians to establish prognosis and hopefully improve the condition of patients with adolescent idiopathic scoliosis.

AIM To investigate the reliability and concurrent validity of the Baseline® Body Level/Scoliosis meter for adolescent idiopathic scoliosis postural assessment in three anatomical planes. METHODS This is an observational reliability and concurrent validity study of adolescent referrals to the Orthopaedic department for scoliosis screening at Karolinska University Hospital, Stockholm, Sweden between March-May 2012. A total of 31 adolescents with idiopathic scoliosis (13.6 ± 0.6 years old) of mild-moderate curvatures (25° ± 12°) were consecutively recruited. Measurement of cervical, thoracic and lumbar curvatures, pelvic and shoulder tilt, and axial thoracic rotation (ATR) were performed by two trained physiotherapists in one day. The intraclass correlation coefficient (ICC) was used to determine the inter-examiner reliability (ICC2,1) and the intra-rater reliability (ICC3,3) of the Baseline® Body Level/Scoliosis meter. Spearman’s correlation analyses were used to estimate concurrent validity between the Baseline® Body Level/Scoliosis meter and Gold Standard Cobb angles from radiographs and the Orthopaedic Systems Inc. Scoliometer. RESULTS There was excellent reliability between examiners for thoracic kyphosis (ICC2,1 = 0.94), ATR (ICC2,1 = 0.92) and lumbar lordosis (ICC2,1 = 0.79). There was adequate reliability between examiners for cervical lordosis (ICC2,1 = 0.51), however poor reliability for pelvic and shoulder tilt. Both devices were reproducible in the measurement of ATR when repeated by one examiner (ICC3,3 0.98-1.00). The device had a good correlation with the Scoliometer (rho = 0.78). When compared with Cobb angle from radiographs, there was a moderate correlation for ATR (rho = 0.627). CONCLUSION The Baseline® Body Level/Scoliosis meter provides reliable transverse and sagittal cervical, thoracic and lumbar measurements and valid transverse plan measurements of mild-moderate scoliosis deformity.

Adolescent idiopathic scoliosis, a lateral curvature of the spine of unknown cause with a Cobb angle of at least 10°, occurs in children and adolescents aged 10 to 18 years. Idiopathic scoliosis is the most common form and usually worsens during adolescence before skeletal maturity. Severe spinal curvature may be associated with adverse long-term health outcomes (eg, pulmonary disorders, disability, back pain, psychological effects, cosmetic issues, and reduced quality of life). Early identification and effective treatment of mild scoliosis could slow or stop curvature progression before skeletal maturity, thereby improving long-term outcomes in adulthood. To update the 2004 US Preventive Services Task Force (USPSTF) recommendation on screening for idiopathic scoliosis in asymptomatic adolescents. The USPSTF reviewed the evidence on the benefits and harms of screening for and treatment of adolescent idiopathic scoliosis. The USPSTF found no direct evidence on screening for adolescent idiopathic scoliosis and health outcomes and no evidence on the harms of screening. The USPSTF found inadequate evidence on treatment with exercise and surgery. It found adequate evidence that treatment with bracing may slow curvature progression in adolescents with mild or moderate curvature severity (Cobb angle <40° to 50°); however, evidence on the association between reduction in spinal curvature in adolescence and long-term health outcomes in adulthood is inadequate. The USPSTF found inadequate evidence on the harms of treatment. Therefore, the USPSTF concludes that the current evidence is insufficient and that the balance of benefits and harms of screening for adolescent idiopathic scoliosis cannot be determined. The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for adolescent idiopathic scoliosis in children and adolescents aged 10 to 18 years.

Surgery, particularly thoracotomy in the thoracic area in infancy has been implicated in the development of scoliosis of thoracogenic origin. The aim of this study was to determine the influence of lateral thoracotomy on scoliosis development in subjects with patent ductus arteriosus. A group of 69 patients with patent ductus arteriosus was evaluated. 38 patients were operated using left lateral thoracotomy and 31 patients were treated non-operatively using intravascular coil implantation. A spinal examination together with the evaluation of spinal roentgenograms was conducted. There was clinical scoliosis in 55% of operated, in 16% of non-operated patients. Scoliosis ranged between 10 and 42 degrees. 76% of operated patients with scoliosis had thoracic curves and in 57% of them left sided curves were found. All curves were right sided in non-operated subjects. Scoliosis in the operated group occurred in 68% of males and in 37% of females. Prevalence of scoliosis after thoracotomy was significantly higher than in the average population and after non-surgical methods of treatment of patent ductus arteriosus. The rate of single thoracic and the rate of left thoracic curves in patients after thoracotomy is higher than the rate in non-operated patients and in idiopathic scoliosis. Female to male ratio with scoliosis and after thoracotomy is significantly lower than in idiopathic scoliosis.

'Lumbar Degenerative Kyphosis' Is Not Byword for Degenerative Sagittal Imbalance: Time to Replace a Misconception.

Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal deformity. Unlike what its name suggests, LDK does not only include sagittal balance disorder of the lumbar spine and kyphosis, but also sagittal balance disorder of the whole spine and little lordosis of the lumbar spine. Moreover, this disease is closely related to the occupation of female farmers and an outdated Asian life style. These reasons necessitate a change in the nomenclature of this disorder to prevent misunderstanding. We suggest the name "primary degenerative sagittal imbalance" (PDSI), which encompasses degenerative sagittal misalignments of unknown origin in the whole spine in older-age patients, and is associated with back muscle wasting. LDK may be regarded as a subgroup of PDSI related to an occupation in agriculture. Conservative treatments such as exercise and physiotherapy are recommended as first-line treatments for patients with PDSI, and surgical treatment is considered only if conservative treatments failed. The measurement of spinopelvic parameters for sagittal balance is important prior to deformity corrective surgery. LDK can be considered a subtype of PDSI that is more likely to occur in female farmers, and hence the use of LDK as a global term for all degenerative sagittal imbalance disorders is better avoided. To avoid confusion, we recommend PDSI as a newer, more accurate diagnostic term instead of LDK.

A new development of correcting exercises has been derived from the original Schroth program in 2010 and the preliminary results have been published that year. Since then the program has been applied in some centers worldwide. As the original Schroth program was the only program so far to improve many signs and symptoms of scoliosis besides the angle of curvature (Cobb angle) it was interesting to look for the preliminary results of the recent development of scoliosis pattern specific corrective exercises derived from the original program, to see if similar effects can be achieved with this less complicated method. A manual search in Pubmed was conducted, using the key words, Schroth, rehabilitation, and idiopathic scoliosis. Three papers have been found describing the short-term results of this new development today called Schroth Best Practice program (SBP). The papers were reviewed and analyzed with respect to the outcome parameters used. Outcome parameters were Angle of Trunk Rotation (ATR), Vital Capacity (VC), surface topography, electromyography, stabilometry and Cobb angle before and after a course of treatment. There was a significant improvement of all parameters after the application of this new program in all the three papers in the short- to mid-term. Scoliosis corrective exercises are supported by two randomized controlled trials (RCT) and should regularly be applied in mild scoliosis at risk for progression. Unspecific exercises such as Yoga, Dobomed cannot be regarded as effective as exercises using a well defined scoliosis pattern specific corrective routine.

Adolescent idiopathic scoliosis (AIS) is a progressive growth disease that affects spinal anatomy, mobility, and left-right trunk symmetry. The disease can modify human gait. We aimed to review articles describing the measurement of gait parameters and energy consumption in AIS during walking without any intervention. Literature review. The search strategy was based on the Population Intervention Comparison Outcome method and included all relevant articles published from 1996 to 2015. Articles were searched in MEDLINE via PubMed, Science Direct, Google Scholar, and ISI Web of Knowledge databases. We selected 33 studies investigating the effect of scoliosis deformity on gait parameters and energy expenditure during walking. Most of the studies concluded no significant differences in walking speed, cadence and step width in scoliosis patients and normal participants. However, patients showed decreased hip and pelvic motion, excessive energy cost of walking, stepping pattern asymmetry and ground reaction force asymmetry. We lack consistent evidence of the effect of scoliosis on temporal spatial and kinematic parameters in AIS patients as compared with normal people. However, further research is needed to assess the effect of scoliosis on gait and energy consumption. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

The management of scoliosis in children with cerebral palsy: a review

Gardner, Adrian

2016-01-01

Children who suffer with cerebral palsy (CP) have a significant chance of developing scoliosis during their early years and adolescence. The behavior of this scoliosis is closely associated with the severity of the CP disability and unlike idiopathic scoliosis, it continues to progress beyond skeletal maturity. Conservative measures may slow the progression of the curve, however, surgery remains the only definitive management option. Advances in surgical technique over the last 50 years have provided methods to effectively treat the deformity while also reducing complication rates. The increased risk of surgical complications with these complex patients make decisions about treatment challenging, however with careful pre-operative optimization and post-operative care, surgery can offer a significant improvement in quality of life. This review discusses the development of scoliosis in CP patient, evaluates conservative and surgical treatment options and assesses post-operative outcome. PMID:28097247

Long-term follow-up of untreated patients with adolescent idiopathic scoliosis (AIS) indicates that, with the exception of some extremely severe cases, AIS does not have a significant impact on quality of life and does not result in dire consequences. In view of the relatively benign nature of AIS and the long-term complications of surgery, the indications for treatment should be reviewed. Furthermore, recent studies have shown that scoliosis-specific exercises focusing on postural rehabilitation can positively influence the spinal curvatures in growing adolescents. Experiential postural re-education is a conservative, non-invasive approach, and its role in the management of AIS warrants further study. This article reviews current evidence for the inclusion of various forms of postural reeducation in the management of AIS. Recent comprehensive reviews have been researched including a manual and PubMed search for evidence regarding the effectiveness of physical/postural re-education/physiotherapy programs in growing AIS patients. This search revealed that there were few studies on the application of postural re-education in the management of AIS. These studies revealed that postural re-education in the form of exercise rehabilitation programs may have a positive influence on scoliosis; however, the various programs were difficult to compare. More research is necessary. There is at present Level 1 evidence for the effectiveness of Schroth scoliosis exercises in the management of AIS. Whether this evidence can be extrapolated to include other forms of scoliosis- pattern-specific exercises requires further investigation. Because corrective postures theoretically reduce the asymmetric loading of the spinal deformities and reverse the vicious cycle of spinal curvature progression, their integration into AIS programs may be beneficial and should be further examined.

Back pain and scoliosis in children most commonly present as benign and self-limited entities. However, persistent back pain and/or progressive scoliosis should always be taken seriously in children. Dedicated diagnostic work-up should exclude etiologies that may result in significant morbidity. Clinical evaluation and management require a comprehensive history and physical and neurological examination. A correct imaging approach is important to define a clear diagnosis and should be reserved for children with persistent symptoms or concerning clinical and laboratory findings. This article reviews the role of different imaging techniques in the diagnostic approach to back pain and scoliosis, and offers a comprehensive review of the main imaging findings associated with common and uncommon causes of back pain and scoliosis in the pediatric population.

Various attitudes to the use of corrective exercises in conservative treatment of scoliosis.

In acquired scoliosis, the degree of the curve is initially low and its type becomes apparent only after it has progressed. The characteristics of scoliosis include an abnormal spatial arrangement of individual body segments, which the central nervous system (CNS) interprets as a defect and automatically launches compensatory mechanisms. Neglecting low-degree scoliosis poses a two-fold danger. It usually leads to the development of structural changes, while the child gets used to the abnormal body arrangement, thus reinforcing the poor postural habits. The basic aim of early rehabilitation is to manage the compensatory mechanisms and prevent the development of adverse secondary changes, rehabilitation in scoliosis being no exception.Some cases of scoliosis require surgery. The point is to minimise the changes resulting from the progression of scoliosis. The role of corrective exercises seems to be significant here. However, views on the usefulness of such exercises are sometimes extremely varied, even though both favourable and sceptical opinions are not fully supported by the literature. However, a number of reports indicate that corrective exercises are useful.
The selection and of corrective exercises and how they should be performed are another question. A number of methods of conservative treatment of scoliosis have been devised. Currently, none of them is considered a comprehensive regimen since each patient requires an individual approach. The most difficult aspect is to ensure that local correction translates to the automatic maintenance of the corrected body posture in a standing position. This is facilitated by corrective exercises supported with biofeedback.
The aim of this paper is to elucidate this complex issue that often leads to divergent and improper attitudes to the conservative treatment of scoliosis.

Long-Term Effects of Untreated Adolescent Idiopathic Scoliosis: A Review of the Literature

Karavidas, Nikos; Moramarco, Marc; Moramarco, Kathryn

2016-01-01

Currently, adolescent idiopathic scoliosis (AIS) is principally regarded as benign, but some researchers have cited serious or extreme effects, including severe pain, cardiopulmonary compromise, social isolation, and even early death. Therefore, exploration of the long-term effects of AIS, the most common type of idiopathic scoliosis, is warranted. The purpose of this review was to examine the long-term studies on the natural history of AIS and/or reviews concerning the long-term effects of untreated AIS. A PubMed search was conducted using the key words idiopathic scoliosis, long-term effects and idiopathic scoliosis, natural history. For further analysis, references cited in those studies were reviewed for additional, related evidence not retrieved in the initial PubMed search. A review of the pertinent bibliography showed that older natural history studies did not distinguish between late-onset scoliosis (referred to in this paper as AIS) and early-onset scoliosis (EOS). The more recent studies offer such important distinction and reach to the general conclusion that untreated AIS does not lead to severe consequences with respect to signs and symptoms of scoliosis. It is possible that earlier studies may have included patient populations with EOS, leading to the perception of untreated scoliosis as having an unusually high morbidity rate. Studies on the long-term effects of AIS that specifically excluded EOS patients conclude that AIS is a benign disorder. This indicates that for research and reporting purposes, it is important to distinguishing between AIS and EOS. This will allow the practitioner and patient and their families to decide on an optimal treatment plan based on the most appropriate prognosis. PMID:27994795

Intrathecal Baclofen Therapy in a Child With Severe Scoliosis: Report of 2 Cases.

Scoliosis is commonly found in children with cerebral palsy. Many patients with cerebral palsy and scoliosis undergo intrathecal baclofen (ITB) pump placement. The authors report 2 cases with cerebral palsy and severe scoliosis treated with intrathecal baclofen. The case of a 7-year-old boy with shunted hydrocephalus required surgical revision of the intrathecal catheter, while the other patient without shunt did not require revision. In the patient with shunted hydrocephalus, after the initial placement of baclofen pump and catheter at Th3 level, spasticity of lower extremities did not improve. The Indium(111) diethylenetriamine pentaacetic acid (In(111) DTPA) scintigraphy with injection of In(111) DTPA through the pump did not demonstrate distribution of the tracer to the lumbosacral area. Conversely, by direct injection of In(111) DTPA through lumbar puncture, the tracer distributed in the whole spinal canal. Replacement of the tip of the catheter caudal to the curve of the scoliosis improved the symptom. The authors suggest that, in patients with severe scoliosis and shunted hydrocephalus, it may be necessary to place the tip of the catheter caudal to the curve of the scoliosis for correction of spasticity of lower extremities. © 2016 International Neuromodulation Society.

Primary ciliary dyskinesia (PCD) is a respiratory syndrome in which 'random' organ orientation can occur; with approximately 46% of patients developing situs inversus totalis at organogenesis. The aim of this study was to explore the relationship between organ anatomy and curve convexity by studying the prevalence and convexity of idiopathic scoliosis in PCD patients with and without situs inversus. Chest radiographs of PCD patients were systematically screened for existence of significant lateral spinal deviation using the Cobb angle. Positive values represented right-sided convexity. Curve convexity and Cobb angles were compared between PCD patients with situs inversus and normal anatomy. A total of 198 PCD patients were screened. The prevalence of scoliosis (Cobb >10°) and significant spinal asymmetry (Cobb 5-10°) was 8 and 23%, respectively. Curve convexity and Cobb angle were significantly different within both groups between situs inversus patients and patients with normal anatomy (P ≤ 0.009). Moreover, curve convexity correlated significantly with organ orientation (P < 0.001; ϕ = 0.882): In 16 PCD patients with scoliosis (8 situs inversus and 8 normal anatomy), except for one case, matching of curve convexity and orientation of organ anatomy was observed: convexity of the curve was opposite to organ orientation. This study supports our hypothesis on the correlation between organ anatomy and curve convexity in scoliosis: the convexity of the thoracic curve is predominantly to the right in PCD patients that were 'randomized' to normal organ anatomy and to the left in patients with situs inversus totalis.

To test for rare genetic mutations, a cohort of patients with unexplained early-onset scoliosis (EOS) was screened using high-density microarray genotyping. A cohort of patients with adolescent idiopathic scoliosis (AIS) was similarly screened and the results were compared. Patients with scoliosis in infancy or early childhood (EOS) are at high risk for progressive deformity and associated problems including respiratory compromise. Early-onset scoliosis is frequently associated with genetic disorders but many patients present with nonspecific clinical features and without an associated diagnosis. The authors hypothesized that EOS in these patients may be caused by rare genetic mutations detectable by next-generation genomic methods. The researchers identified 24 patients with unexplained EOS from pediatric orthopedic clinics. They genotyped them, along with 39 connecting family members, using the Illumina OmniExpress-12, version 1.0 beadchip. Resulting genotypes were analyzed for chromosomal changes, specifically copy number variation and absence of heterozygosity. They screened 482 adolescent idiopathic scoliosis (AIS) patients and 744 healthy controls, who were similarly genotyped with the same beadchip, for chromosomal changes identified in the EOS cohort. Copy number variation and absence of heterozygosity analyses revealed a genetic diagnosis of chromosome 15q24 microdeletion syndrome in 1 patient and maternal uniparental disomy of chromosome 14 in a second one. Prior genetic testing and clinical evaluations had been negative in both cases. A large novel chromosome 10 deletion was likely causal in a third EOS patient. These mutations identified in the EOS patients were absent in AIS patients and controls, and thus were not associated with AIS or found in asymptomatic individuals. These data underscore the usefulness of updated genetic evaluations including high-density microarray-based genotyping and other next-generation methods in patients with unexplained

To study family history in relation to curve severity, gender, age at diagnosis and treatment in idiopathic scoliosis. A self-assessment questionnaire on family history of scoliosis was administered to 1,463 untreated, brace or surgically treated idiopathic scoliosis patients. Out of the 1,463 patients, 51 % had one or more relatives with scoliosis. There was no significant difference between females and males, nor between juvenile and adolescent study participants in this respect (p = 0.939 and 0.110, respectively). There was a significant difference in maximum curve size between patients with one or more relatives with scoliosis (median 35°, interquartile range 25) and patients without any relative with scoliosis (median 32°, interquartile range 23) (p = 0.022). When stratifying patients according to treatment (observation, brace treatment or surgery), we found that it was more common to have a relative with scoliosis among the treated patients (p = 0.011). The OR for being treated was 1.32 (95% CI 1.06-1.64) when the patient had a relative with scoliosis, compared to not having. Larger curve sizes were found in patients with a family history of scoliosis than in the ones without. No relation between family history and gender or between family history and age at onset of idiopathic scoliosis was found. Although the presence of a family history of scoliosis may not be a strong prognostic risk factor, it indicates that these patients are at higher risk of developing a more severe curve.

Posterior hemivertebra resection with short fusion has gradually become the mainstream treatment for the congenital scoliosis due to single fully segmented hemivertebra. A kind of unexpected emerging S-shaped scoliosis was found secondary to this surgery, and that has not been reported yet. The aim of the present study was to analyze the possible pathogenesis, clinical feature, and treatment of the emerging S-shaped scoliosis after posterior hemivertebra resection and short fusion. This study is a retrospective case series. A total of 128 patients participated. Preoperative and postoperative whole spine radiographs were used to measure the Cobb angle of main curve, compensatory curve, and emerging curves. And the hemivertebra location, the fused segment, the apical and ending vertebrae of postoperative-emerging curve (and preoperative compensatory curves) were assessed. Both the demographics and radiographic data were reviewed. Postoperative-emerging scoliosis was defined as the curve with an increasing angle of 20° and an apical vertebra locating at least two levels away from fusion region. Of the 128 patients, 9 (7%) showed postoperative-emerging S-shaped scoliosis. The mean age was 11.4 years old. The mean main curve was 36.1±14.4° preoperatively and been significantly corrected to 6.9±6.1° (p<.001). No significant difference was found in the main curve, kyphosis, coronal balance, or sagittal balance during follow-up. The emerging scoliosis occurred at 3 months (in four patients) or 6 months (in five patients) after initial surgery with an average angle of 42.6±12.9° at last follow-up. All patients underwent bracing or observation when the S-shaped scoliosis was arising, and four patients underwent a revision surgery because of deformity developing. The emerging S-shaped scoliosis was an extraordinary complication that may be developing from the preoperative compensatory scoliosis and usually occurred at 3-6 months after hemivertebra resection.

Adolescent idiopathic scoliosis (AIS) is a deformity of the spine manifested by asymmetry and deformities of the external surface of the trunk. Classification of scoliosis deformities according to curve type is used to plan management of scoliosis patients. Currently, scoliosis curve type is determined based on X-ray exam. However, cumulative exposure to X-rays radiation significantly increases the risk for certain cancer. In this paper, we propose a robust system that can classify the scoliosis curve type from non invasive acquisition of 3D trunk surface of the patients. The 3D image of the trunk is divided into patches and local geometric descriptors characterizing the surface of the back are computed from each patch and forming the features. We perform the reduction of the dimensionality by using Principal Component Analysis and 53 components were retained. In this work a multi-class classifier is built with Least-squares support vector machine (LS-SVM) which is a kernel classifier. For this study, a new kernel was designed in order to achieve a robust classifier in comparison with polynomial and Gaussian kernel. The proposed system was validated using data of 103 patients with different scoliosis curve types diagnosed and classified by an orthopedic surgeon from the X-ray images. The average rate of successful classification was 93.3% with a better rate of prediction for the major thoracic and lumbar/thoracolumbar types.

Objective To determine the relationship between whole body vibration (WBV) induced helicopter flights and degenerative changes of the cervical and lumbar spine. Methods We examined 186 helicopter pilots who were exposed to WBV and 94 military clerical workers at a military hospital. Questionnaires and interviews were completed for 164 of the 186 pilots (response rate, 88.2%) and 88 of the 94 clerical workers (response rate, 93.6%). Radiographic examinations of the cervical and the lumbar spines were performed after obtaining informed consent in both groups. Degenerative changes of the cervical and lumbar spines were determined using four radiographs per subject, and diagnosed by two independent, blinded radiologists. Results There was no significant difference in general and work-related characteristics except for flight hours and frequency between helicopter pilots and clerical workers. Degenerative changes in the cervical spine were significantly more prevalent in the helicopter pilots compared with control group. In the cervical spine multivariate model, accumulated flight hours (per 100 hours) was associated with degenerative changes. And in the lumbar spine multivariate model, accumulated flight hours (per 100 hours) and age were associated with degenerative changes. Conclusion Accumulated flight hours were associated with degenerative changes of the cervical and lumbar spines in helicopter pilots. PMID:24236259

It is relatively common for a scoliosis deformity to be associated with a lumbar spondylolisthesis in adolescents (up to 48 % of spondylolistheses). In the literature two types of curve have been described: 'sciatic' or 'olisthetic'. However, there is no consensus in the literature on how best to treat these deformities. Some authors advocate a single surgical intervention, where both deformities are corrected; whereas, others advocate treating them as separate entities. In this situation, it has been shown that the scoliosis will correct with treatment of the spondylolisthesis. We present a 12-year-old girl who had a concomitant high-grade spondylolisthesis and scoliosis. Her main complaints were those of low back pain and an L5 radiculopathy. We took the decision to treat the spondylolisthesis surgically, but observe the scoliosis, rather than correcting them both surgically at the same sitting. Although the immediately post-operative radiographs showed persistence of the scoliosis, 1-year follow-up demonstrated full resolution of the deformity. This young lady also had relief of her low back pain and leg pain following the surgery. There are no standard guidelines and therefore, we discuss the management of this difficult problem, exemplifying a case of a young girl who had high-grade spondylolisthesis along with a clinically non-flexible scoliosis treated at our institution. We demonstrate that it is safe to observe the scoliosis, even in high-grade spondylolistheses.

A case-control study. To compare health-related quality of life and low back pain of healthy subjects with those of patients with nonidiopathic scoliosis (non-IS) and idiopathic scoliosis (IS) 21 years or more after surgery. There have been a very small number of reports on long-term results of surgery for non-IS. There have not been any reports that compare non-IS, IS, and healthy subjects. The subjects with scoliosis were 602 patients who had undergone surgery between 1968 and 1988. The Scoliosis Research Society Patient Questionnaire (SRS-22), Roland-Morris Disability Questionnaire (RDQ), and our institution's original questionnaire were used for evaluating long-term clinical outcomes. The 136 respondents consisted of 56 patients with non-IS (non-IS group) and 80 patients with IS (IS group). The control group (CTR group) consisted of 80 healthy volunteers who were age- and body mass index-matched to the scoliosis groups. In the SRS-22, the 3 groups had no significant differences in pain and mental health. For function and self-image, the non-IS group and the IS group had a significantly lower score than the CTR group. In the RDQ, the non-IS group had significantly more severe low back pain than the CTR group. There was no significant difference in low back pain between the non-IS group and IS group or between the IS group and CTR group. The non-IS group had a significantly lower marriage rate than the IS and CTR groups. The patients with non-IS and IS had similar health-related quality of life and low back pain. The patients with non-IS were found to have lower function and self-image in the SRS-22 questionnaire and more severe low back pain in the RDQ than healthy subjects. The patients with non-IS had a significantly lower marriage rate than the other 2 groups.

A Modern Historical Perspective of Schroth Scoliosis Rehabilitation and Corrective Bracing Techniques for Idiopathic Scoliosis.

The treatment of scoliosis has a long history dating back to Hippocrates and his luxation table. In recent history, conservative rehabilitation treatment methods have come and gone. Some have had more longevity than others and currently there are only a handful of these "schools" for rehabilitation in existence. What is important to note in this twenty-first century world is that any approach to bracing or scoliosis rehabilitation must strive for a correction effect and be as user-friendly as possible. Patients look to achieve some measure of success, whether it be halted Cobb angle, improved breathing function, decreased rotation, or postural improvement via trunk symmetry. Katharina Schroth created her method in 1921 as a result of self-analysis of her own imperfect scoliotic torso and the effect on it as she altered her breathing patterns. It was from these observations and self-experimentation that she devised her rotational angular breathing method. Subsequently, the Schroth method evolved under the leadership of her daughter, Christa Lehnert-Schroth P.T., and grandson, Dr. Hans-Rudolf Weiss. Collaboration with Dr. Jacques Chêneau led to a new Schroth method compatible scoliosis bracing approach. The most recent advancement of Chêneau bracing is the Gensingen Brace® (GBW). Gensingen braces have an asymmetric design and rely on Schroth principles of correction in a smaller, lighter, more wearer-friendly brace. Each brace is designed to be a complementary supportive orthosis. It may be used independently, or in conjunction with Schroth exercise protocols.

Significant prevalence rates of adolescent scoliosis in China were suggested in previous studies. However, school screenings for adolescent scoliosis have been suspended due to low rates of positive detection under the past screening system in China. The present study was undertaken to screen for adolescent scoliosis in middle school students under a modern assessment system in a district of Shanghai. We performed a population-based, cross-sectional study of a middle school scoliosis screening program in the Jingan district. In 2015, schoolchildren were initially screened by visual inspection of clinical signs and the forward-bending test. Suspected cases were referred for radiography in hospital for scoliosis diagnosis. A total of 5327 middle school students (grades 6-8) were screened with 520 (9.76%) positives (the positive rates of girls and boys at 15.28% and 4.59%, respectively) and no statistically significant difference among grades. Only 301 positives (57.9%) followed the referral for hospital radiography. There were 102 cases (33.9%) that were diagnosed with scoliosis by radiography criteria (Cobb angle ≥10°) including mild scoliosis (Cobb 10-25) for 94 cases and moderate scoliosis (Cobb 25-40) for 8 cases, and false-positives (Cobb 0) for 39 cases. The putative prevalence rate was estimated as 1.9% from the referred students. Under an accurate and modern assessment system, school screenings can detect scoliosis at a significant rate, but awareness of scoliosis risks is needed for residents in China to take up referrals for hospital diagnosis after school screenings.

Abstract The aim of this study was to identify the prevalence of proximal junctional kyphosis (PJK) in degenerative lumbar scoliosis (DLS) following long instrumented posterior spinal fusion, and to search for predictable risk factors for the progression of junctional kyphosis. In total 98 DLS patients with a minimum 2-year follow-up were reviewed prospectively. According to the occurrence of PJK at the last follow-up, patients were divided into 2 groups: PJK group and non-PJK group. To investigate risk values for the progression of PJK, 3 categorized factors were analyzed statistically: patient characteristics—preoperative data of age, sex, body mass index (BMI), bone mineral density (BMD) were investigated; surgical variables—the most proximal and distal levels of the instrumentation, the number of instrumented levels; pre- and postoperative radiographic parameters include the scoliotic angle, sagittal vertical axis, thoracic kyphosis, thoracolumbar junctional angle, lumbar lordosis, pelvic incidence, pelvic tilt, and sacral slope. PJK was developed in 17 of 98 patients (17.3%) until to the final follow-up and were enrolled as the PJK group, and 81 patients without PJK at final follow-up were enrolled as the non-PJK group. There was no statistically significant difference between the 2 groups in age at operation (P = 0.900). The patient's sex was excluded in statistical analysis because of the predominance of female patients. There were statistically significant difference between the 2 groups in BMI ([25.5 ± 1.7] kg/m2 in the PJK group and [23.6 ± 1.9] kg/m2 in the non-PJK group, P < 0.001) and BMD ([–1.4 ± 0.8] g/cm2 in the PJK group and [−0.7 ± 0.3] g/cm2 in the non-PJK group, P < 0.001). No specific surgery-related variables were found to be associated with an increased risk of developing PJK, except when the most proximal instrumented vertebrae stopped at thoracolumbar junction (T11-L1).

When compared to boys, girls have smaller vertebral cross-sectional area, which conveys a greater spinal flexibility, and a higher prevalence of adolescent idiopathic scoliosis. To test the hypothesis that small vertebral cross-sectional area and tall intervertebral disc height are structural characteristics of patients with adolescent idiopathic scoliosis. Using multiplanar imaging techniques, measures of vertebral cross-sectional area, vertebral height and intervertebral disc height in the lumbar spine were obtained in 35 pairs of girls and 11 pairs of boys with and without adolescent idiopathic scoliosis of the thoracic spine matched for age, height and weight. Compared to adolescents without spinal deformity, girls and boys with adolescent idiopathic scoliosis had, on average, 9.8% (6.68 ± 0.81 vs. 7.40 ± 0.99 cm(2); P = 0.0007) and 13.9% (8.22 ± 0.84 vs. 9.55 ± 1.61 cm(2); P = 0.009) smaller vertebral cross-sectional dimensions, respectively. Additionally, patients with adolescent idiopathic scoliosis had significantly greater values for intervertebral disc heights (9.06 ± 0.85 vs. 7.31 ± 0.62 mm and 9.09 ± 0.87 vs. 7.61 ± 1.00 mm for girls and boys respectively; both P ≤ 0.011). Multiple regression analysis indicated that the presence of scoliosis was negatively associated with vertebral cross-sectional area and positively with intervertebral disc height, independent of sex, age and body mass index. We provide new evidence that girls and boys with adolescent idiopathic scoliosis have significantly smaller vertebral cross-sectional area and taller intervertebral disc heights - two major structural determinants that influence trunk flexibility. With appropriate validation, these findings may have implications for the identification of children at the highest risk for developing scoliosis.

‘Lumbar Degenerative Kyphosis’ Is Not Byword for Degenerative Sagittal Imbalance: Time to Replace a Misconception

Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal deformity. Unlike what its name suggests, LDK does not only include sagittal balance disorder of the lumbar spine and kyphosis, but also sagittal balance disorder of the whole spine and little lordosis of the lumbar spine. Moreover, this disease is closely related to the occupation of female farmers and an outdated Asian life style. These reasons necessitate a change in the nomenclature of this disorder to prevent misunderstanding. We suggest the name “primary degenerative sagittal imbalance” (PDSI), which encompasses degenerative sagittal misalignments of unknown origin in the whole spine in older-age patients, and is associated with back muscle wasting. LDK may be regarded as a subgroup of PDSI related to an occupation in agriculture. Conservative treatments such as exercise and physiotherapy are recommended as first-line treatments for patients with PDSI, and surgical treatment is considered only if conservative treatments failed. The measurement of spinopelvic parameters for sagittal balance is important prior to deformity corrective surgery. LDK can be considered a subtype of PDSI that is more likely to occur in female farmers, and hence the use of LDK as a global term for all degenerative sagittal imbalance disorders is better avoided. To avoid confusion, we recommend PDSI as a newer, more accurate diagnostic term instead of LDK. PMID:28264231

Retrospective sequential patient series. To establish the relationship between the magnitude of the deformity in scoliosis and patients' perception of their condition, as measured with Scoliosis Research Society-22 scores. A total of 93 untreated patients with adolescent idiopathic scoliosis were included retrospectively. The Cobb angle was measured from a plain radiograph, and volumetric asymmetry was measured by ISIS2 surface topography. The association between Scoliosis Research Society scores for function, pain, self-image, and mental health against Cobb angle and volumetric asymmetry was investigated using the Pearson correlation coefficient. Correlation of both Cobb angle and volumetric asymmetry with function and pain was weak (all < .23); these correlation values were not statistically significant. Correlation of Cobb angle and volumetric asymmetry with self-image, was higher, although still moderate (-.37 for Cobb angle and -.44 for volumetric asymmetry). Both were statistically significant (Cobb angle, p = .0002; volumetric asymmetry; p = .00001). Cobb angle contributed 13.8% to the linear relationship with self-image, whereas volumetric asymmetry contributed 19.3%. For mental health, correlation was statistically significant with Cobb angle (p = .011) and volumetric asymmetry (p = .0005), but the correlation was low to moderate (-.26 and -.35, respectively). Cobb angle contributed 6.9% to the linear relationship with mental health, whereas volumetric asymmetry contributed 12.4%. Volumetric asymmetry correlates better with both mental health and self-image compared with Cobb angle, but the correlation was only moderate. This study suggests that a patient's own perception of self-image and mental health is multifactorial and not completely explained through present objective measurements of the size of the deformity. This helps to explain the difficulties in any objective analysis of a problem with multifactorial perception issues. Further study is

Idiopathic scoliosis: the tethered spine II: post-surgical pain.

PubMed

Whyte Ferguson, Lucy

2014-10-01

The treatment of severe chronic pain in young people following surgery for the correction of curvatures of idiopathic scoliosis (IS) is presented through two case histories. Effective treatment involved release of myofascial trigger points (TrPs) known to refer pain into the spine, and treatment of related fascia and joint dysfunction. The TrPs found to be contributing to spinal area pain were located in muscles at some distance from the spine rather than in the paraspinal muscles. Referred pain from these TrPs apparently accounted for pain throughout the base of the neck and thoracolumbar spine. Exploratory surgery was considered for one patient to address pain following rod placement but the second surgery became unnecessary when the pain was controlled with treatment of the myofascial pain and joint dysfunction. The other individual had both scoliosis and hyperkyphosis, had undergone primary scoliosis surgery, and subsequently underwent a second surgery to remove hardware in an attempt to address her persistent pain following the initial surgery (and because of dislodged screws). The second surgery did not, however, reduce her pain. In both cases these individuals, with severe chronic pain following scoliosis corrective surgery, experienced a marked decrease of pain after myofascial treatment. As will be discussed below, despite the fact that a significant minority of individuals who have scoliosis corrective surgery are thought to require a second surgery, and despite the fact that pain is the most common reason leading to such revision surgery, myofascial pain syndrome (MPS) had apparently not previously been considered as a possible factor in their pain.

An unusually high prevalence (10%) of scoliosis is described in a series of 151 patients aged four years and older with cystic fibrosis. The scolioses were of the late onset (juvenile and adolescent) type, being typically thoracic with the curve convex to the right, although there was no significant preference for either sex. No direct relationship was found between the spinal curvature and the severity or distribution of the lung disease, although the worse scolioses tended to occur in patients with relatively severe pulmonary involvement. There was no evidence of metabolic bone disease as a predisposing cause. Some indication ofmore » a familial tendency towards scoliosis was apparent, and a genetic or constitutional basis is postulated with an unknown precipitating factor.« less

Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine . While AIS can progress during growth and cause a surface deformity, it is usually not symptomatic. However, in adulthood, if the final spinal curvature surpasses a certain critical threshold, the risk of health problems and curve progression is increased. The use of scoliosis-specific exercises (SSE) to reduce progression of AIS and postpone or avoid other more invasive treatments is controversial. To evaluate the efficacy of SSE in adolescent patients with AIS. The following databases (up to 30 March 2011) were searched with no language limitations: CENTRAL (The Cochrane Library 2011, issue 2), MEDLINE (from January 1966), EMBASE (from January 1980), CINHAL (from January 1982), SportDiscus (from January 1975), PsycInfo (from January 1887), PEDro (from January 1929). We screened reference lists of articles and also conducted an extensive handsearch of grey literature. Randomised controlled trials and prospective cohort studies with a control group comparing exercises with no treatment, other treatment, surgery, and different types of exercises. Two review authors independently selected studies, assessed risk of bias and extracted data. Two studies (154 participants) were included. There is low quality evidence from one randomised controlled study that exercises as an adjunctive to other conservative treatments increase the efficacy of these treatments (thoracic curve reduced: mean difference (MD) 9.00, (95% confidence interval (CI) 5.47 to 12.53); lumbar curve reduced:MD 8.00, (95% CI 5.08 to 10.92)). There is very low quality evidence from a prospective controlled cohort study that scoliosis-specific exercises structured within an exercise programme can reduce brace prescription (risk ratio (RR) 0.24, (95% CI 0.06 to1.04) as compared to usual physiotherapy (many different kinds of general exercises according to the preferences of the single therapists within different facilities

Most scoliosis are idiopathic (80%) and occur more frequently in adolescent girls. Plain radiography is the imaging method of choice, both for the initial study and follow-up studies but has the disadvantage of using ionizing radiation. The breasts are exposed to x-ray along these repeated examinations. The authors present a range of recommendations in order to optimize radiographic exam technique for both conventional and digital x-ray settings to prevent unnecessary patients' radiation exposure and to reduce the risk of breast cancer in patients with scoliosis. With analogue systems, leaded breast protectors should always be used, and with any radiographic equipment, analog or digital radiography, the examination should be performed in postero-anterior projection and optimized low-dose techniques. The ALARA (as low as reasonable achievable) rule should always be followed to achieve diagnostic quality images with the lowest feasible dose. Copyright © 2014. Published by Elsevier Espana.

Acquired deformations of spinal cord (scoliosis, kyphosis, lordosis) represent a frequent pathology in child; their treatment is complex, with variable results which depend on various parameters. Mild scoliosis, with an angle less than 30 degrees, is treated with physiotherapy and regular follow-up. If the angle is higher than 30 degrees, the orthopedic corset is required; the angle over 45 degrees impose surgically correction. The indications of every therapeutic method depend on many factors, the main target of the treatment is to prevent the aggravation of the curvature; concerning the surgery, the goal is to obtain a correction as normal as possible of the spinal axis.

Longitudinal cohort study. To compare functional outcomes between male and female patients before and after surgery for adolescent idiopathic scoliosis (AIS). There is no clear consensus in the existing literature with respect to sex differences in functional outcomes in the surgical treatment of AIS. A prospective, consecutive, multicenter database of patients who underwent surgical correction for adolescent idiopathic scoliosis was analyzed retrospectively. All patients completed Scoliosis Research Society-30 (SRS-30) questionnaires before and 2 years after surgery. Patients with previous spine surgery were excluded. Data were collected for sex, age, Risser grade, previous bracing history, maximum preoperative Cobb angle, curve correction at 2 years, and SRS-30 domain scores. Paired sample t tests were used to compare preoperative and postoperative scores within each sex. Independent sample t tests were used to compare scores between sexes. A P value of <0.05 was considered statistically significant. Seven hundred forty-four patients (621 females and 123 males) were included. On average, males were 1 year older than females. There were no differences between sexes in Risser grade, bracing history, maximum curve magnitude, or correction after surgery. Both males and females had similar improvement in all SRS-30 domains after surgery. Self-image/appearance had the greatest relative improvement. Males had better self-image/appearance scores preoperatively, better pain scores at 2 years, and better mental health and total scores both preoperatively and at 2 years. Both males and females were similarly satisfied with surgery. Males treated with surgery for AIS report better preoperative self-image, less postoperative pain, and better mental health than females. These differences may be clinically significant. For both males and females, the most beneficial effect of surgery is improved self-image/appearance. Overall, the benefits of surgery for AIS are similar for

Although the role of laparoscopic nephrectomy (LN) has been established, few studies have reported cases of LN in individuals with scoliosis. Here we report a case of right LN in a patient with severe right convex scoliosis. A 26-year-old man presented with a fever. His medical history comprised severe right convex lumbar scoliosis. CT revealed right hydronephrosis and right kidney stones. Pyelonephritis requiring nephrectomy was diagnosed. Right LN was feasible with elaborate perioperative care. The postoperative course was uneventful with no relapse of urinary tract infection. © 2018 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Purpose The purposes of this study were to evaluate the usefulness and limitations of chest radiographs in scoliosis screening and to compare these results with those of thoraco-lumbar standing radiographs (TLSR). Materials and Methods During Korean conscription, 419 males were retrospectively examined using both chest radiographs and TLSR to confirm the scoliosis and Cobb angle at the Regional Military Manpower. We compared the types of spinal curves and Cobb angles as measured from different radiographs. Results In the pattern of spinal curves, the overall matching rate of chest radiographs using TLSR was about 58.2% (244 of 419 cases). Cobb angle differences between chest radiographs and TLSR with meaningful difference was observed in 156 cases (37.2%); a relatively high proportion (9.5%) of Cobb angle differences more than 10 degrees was also observed. The matching rate of both spinal curve types and Cobb angle accuracy between chest radiographs and TLSR was 27.9% (117 among 419 cases). Chest radiographs for scoliosis screening were observed with 93.94% of sensitivity and 61.67% of specificity in thoracic curves; however, less than 40% of sensitivity (38.27%, 20.00%, and 25.80%) and more than 95% of specificity (97.34%, 99.69%, and 98.45%) were observed in thoraco-lumbar, lumbar, and double major curves, respectively. Conclusion The accuracy of chest radiographs for scoliosis screening was low. The incidence of thoracic curve scoliosis was overestimated and lumbar curve scoliosis was easily missed by chest radiography. Scoliosis screening using chest radiography has limited values, nevertheless, it is useful method for detecting thoracic curve scoliosis. PMID:23074120

Nineteenth century exercise clinics for the treatment of scoliosis.

Elsaesser, S; Butler, A R

Scoliosis is the abnormal lateral curvature and rotation of the spine. In the past this deformity has been linked with moral depravity, as in the case of Richard III. Treatment for scoliosis began with Hippocrates's use of boards and axial distortion. Today, bracing and surgery are used either to correct the deformity or to prevent further progression. In the past, however, exercise regimens have been used in the belief that strengthening back muscles would reduce curvature progression. This approach was pioneered by Per Henrik Ling in the early nineteenth century and was continued by his followers Mathius Roth and Franz Berwald and, most notably, by Gustav Zander. Even today a few clinics, particularly in Eastern Europe, still use exercise in the treatment of scoliosis. Whether it is effective remains debatable, but even if progression is not prevented the patient's general health will benefit from an exercise regimen.

Idiopathic scoliosis patients have postural equilibrium problems. The objective of this study was to assess postural control in subjects with idiopathic scoliosis following a 4-month intervention in an unbraced position. Quasi-experimental. Eight healthy girls and eight girls with idiopathic scoliosis took part. A Kistler force platform was used with a frequency of 100 Hz for recording data. The center of pressure was recorded in different positions out of brace for scoliosis and healthy subjects. Test conditions were single limb and double limb stance, with eyes open and closed, and foam and rigid surfaces. The data reflected a weak balance of idiopathic scoliosis subjects compared to healthy subjects. After 1 and 4 months of wearing the brace, center of pressure and center of gravity sway increased in the majority of the tests, although there were no significant differences in any of the test conditions (p > 0.05). While the center of pressure sway in medio-lateral direction decreased after 4 months of wearing a brace, in other variables center of pressure and center of gravity sway increased. Idiopathic scoliosis patients have weak balance in comparison to healthy subjects. In addition, following a period of 4 months of wearing a brace, balance parameters in the scoliosis subjects did not improve. The results show that we need more follow-up of orthoses wearing in idiopathic scoliosis subjects and suggest more studies at least 1-year follow-up to identify the efficiency of brace wear on balance. Scoliosis can alter postural stability and balance performance during quiet standing. Spinal deformity can alter a subject's ability to compensate for postural changes and cause gait deviations. This study investigated balance differences between the healthy and idiopathic scoliosis patients and the results of thoraco lumbo sacral orthosis brace wear. It might provide some new insight into the conservative treatment of idiopathic scoliosis patients for

Joint hypermobility in children with idiopathic scoliosis: SOSORT award 2011 winner

PubMed Central

2011-01-01

Background Generalized joint hypermobility (JHM) refers to increased joint mobility with simultaneous absence of any other systemic disease. JHM involves proprioception impairment, increased frequency of pain within joints and tendency to injure soft tissues while performing physical activities. Children with idiopathic scoliosis (IS) often undergo intensive physiotherapy requiring good physical capacities. Further, some physiotherapy methods apply techniques that increase joint mobility and thus may be contraindicated. The aim of this paper was to assess JHM prevalence in children with idiopathic scoliosis and to analyze the relationship between JHM prevalence and the clinical and radiological parameters of scoliosis. The methods of assessment of generalized joint hypermobility were also described. Materials and methods This case-control study included 70 subjects with IS, aged 9-18 years (mean 13.2 ± 2.2), Cobb angle range 10°-53° (mean 24.3 ± 11.7), 34 presenting single curve thoracic scoliosis and 36 double curve thoracic and lumbar scoliosis. The control group included 58 children and adolescents aged 9-18 years (mean 12.6 ± 2.1) selected at random. The presence of JHM was determined using Beighton scale complemented with the questionnaire by Hakim and Grahame. The relationship between JHM and the following variables was evaluated: curve severity, axial rotation of the apical vertebra, number of curvatures (single versus double), number of vertebrae within the curvature (long versus short curves), treatment type (physiotherapy versus bracing) and age. Statistical analysis was performed with Statistica 8.1 (StatSoft, USA). The Kolmogorov-Smirnov test, U Mann-Whitney test, Chi2 test, Pearson and Spermann correlation rank were conducted. The value p = 0.05 was adopted as the level of significance. Results JHM was diagnosed in more than half of the subjects with idiopathic scoliosis (51.4%), whilst in the control group it was diagnosed in only 19% of cases (p

Locomotor skills and balance strategies in adolescents idiopathic scoliosis.

Locomotor balance control assessment was performed to study the effect of idiopathic scoliosis on head-trunk coordination in 17 patients with adolescent idiopathic scoliosis (AIS) and 16 control subjects. The aim of this study was to explore the functional effects of structural spinal deformations like idiopathic scoliosis on the balance strategies used during locomotion. Up to now, the repercussion of the idiopathic scoliosis on head-trunk coordination and balance strategies during locomotion is relatively unknown. Seventeen patients with AIS (mean age 14 years 3 months, 10 degrees < Cobb angle > 30 degrees) and 16 control subjects (mean age 14 years 1 month) were tested during various locomotor tasks: walking on the ground, walking on a line, and walking on a beam. Balance control was examined in terms of rotation about the vertical axis (yaw) and on a frontal plane (roll). Kinematics of foot, pelvis, trunk, shoulder, and head rotations were measured with an automatic optical TV image processor in order to calculate angular dispersions and segmental stabilizations. Decreasing the walking speed is the main adaptive strategy used in response to balance problems in control subjects as well as patients with AIS. However, patients with AIS performed walking tasks more slowly than normal subjects (around 15%). Moreover, the pelvic stabilization is preserved, despite the structural changes affecting the spine. Lastly, the biomechanical defect resulting from idiopathic scoliosis mainly affects the yaw head stabilization during locomotion. Patients with AIS show substantial similarities with control subjects in adaptive strategies relative to locomotor velocity as well as balance control based on segmental stabilization. In contrast, the loss of the yaw head stabilization strategies, mainly based on the use of vestibular information, probably reflects the presence of vestibular deficits in the patients with AIS.

Current concepts and controversies on adolescent idiopathic scoliosis: Part I.

PubMed

Sud, Alok; Tsirikos, Athanasios I

Adolescent idiopathic scoliosis is the most common spinal deformity encountered by General Orthopaedic Surgeons. Etiology remains unclear and current research focuses on genetic factors that may influence scoliosis development and risk of progression. Delayed diagnosis can result in severe deformities which affect the coronal and sagittal planes, as well as the rib cage, waistline symmetry, and shoulder balance. Patient's dissatisfaction in terms of physical appearance and mechanical back pain, as well as the risk for curve deterioration are usually the reasons for treatment. Conservative management involves mainly bracing with the aim to stop or slow down scoliosis progression during growth and if possible prevent the need for surgical treatment. This is mainly indicated in young compliant patients with a large amount of remaining growth and progressive curvatures. Scoliosis correction is indicated for severe or progressive curves which produce significant cosmetic deformity, muscular pain, and patient discontent. Posterior spinal arthrodesis with Harrington instrumentation and bone grafting was the first attempt to correct the coronal deformity and replace in situ fusion. This was associated with high pseudarthrosis rates, need for postoperative immobilization, and flattening of sagittal spinal contour. Segmental correction techniques were introduced along with the Luque rods, Harri-Luque, and Wisconsin systems. Correction in both coronal and sagittal planes was not satisfactory and high rates of nonunion persisted until Cotrel and Dubousset introduced the concept of global spinal derotation. Development of pedicle screws provided a powerful tool to correct three-dimensional vertebral deformity and opened a new era in the treatment of scoliosis.

Cross-sectional observational study to investigate psychometric properties of an adapted Thai version of the refined Scoliosis Research Society-22 (SRS-22) questionnaire. To evaluate the reliability and validity of the adapted Thai version of the refined SRS-22 questionnaire. The SRS-22 questionnaire is a valid instrument for assessing the health-related quality of life for patients with adolescent idiopathic scoliosis. Recently, the questionnaire has been translated and validated in many languages for non-English-speaking countries. Translation/retranslation of the English version of the SRS-22 was conducted, and the cross-cultural adaptation process was performed. The Thai version SRS-22 and previously validated Thai version Short-Form survey version 2.0 (SF-36V2) questionnaires were administered to 77 patients with adolescent idiopathic scoliosis who had surgical treatment. Fifty-eight patients (52 adolescent girls) had filled out the first set of questionnaires. Thirty patients of the first-time responders completed the second set of questionnaires. The mean age at the time of operation was 14.6 years and the mean age at the time of the final follow-up was 18.7 years. The mean preoperative scoliosis curve magnitude was 55.4° (range, 30°-95°) and postoperative curve magnitude was 20.1° (range, 0°-60°). Internal consistency was determined with Cronbach α coefficient. Intraclass correlation coefficient was used for test-retest reliability. Concurrent validity was evaluated by comparing SRS-22 domains with relevant domains in the SF-36V2 questionnaire, using the Pearson correlation coefficient. The mean overall Cronbach α coefficient of the adapted Thai version SRS-22 was 0.76. The 2 of corresponding domains (mental health = 0.80 and self-image = 0.83) had satisfactory internal consistency and the remaining domains (pain = 0.78; function/activity = 0.74; and satisfaction = 0.76) were good.

A comparative study. The aims of this study were to: (1) evaluate Scoliosis Research Society (SRS)-22 questionnaire performance in normal adolescents without scoliosis to establish a normative baseline useful for evaluating the discriminate validity of the SRS-22 in primary adolescent scoliosis; and (2) investigate impact of age and sex on SRS-22 in an adolescent population unaffected by scoliosis. The SRS-22 questionnaire is widely used to measure health-related quality of life of patients with spinal disease including scoliosis and lumbar spondylolisthesis. However, normal data, which are very important, when comparing patients and nonpatients, are few, little, and there are few studies about factors that may affect SRS questionnaire performance. The adolescent population was from 14 schools located in 7 provinces. A total of 2008 adolescents (961 females, 1026 males, 21 unknown; mean age, 14.3 yr; range, 11-20) completed the simplified Chinese version of SRS-22 questionnaire and demographic questions. Surveys were stratified into 8 age-sex groups for analysis: male/female; 12 to 13.4, 13.5 to 14.9, 15 to 15.9, and more than 16 years of age. Post hoc testing and the Tukey least significant difference were used to compare differences between any 2 of the 4 age groups. Self-image scores in males were higher than those in females (P < 0.01). Pain domain scores were significantly higher in males than those in females in the 13.5- to 14.9-year-old subgroup, whereas other subgroups showed no obvious differences. The function domain scores in males who were aged 15 to 15.9 years and those older than 16 years were significantly higher than those in females (P < 0.001). There were no statistically significant differences in mental health domain scores among age-sex subgroups, with the exception of the 13.5- to 14.9-year-old group. This is the first study to characterize the sex and age influence on the SRS-22 scores in normal population. Age and sex have an important

Idiopathic scoliosis, defined as a three-dimensional spine and trunk deformity, which appears in otherwise healthy subjects, exhibits complex relations with various forms of personal well-being and psychopathology. Most research studies have documented a higher proportion of psychological disturbances (e.g., self-criticism, negative body image, low self-esteem) and mental disorders (e.g., anxiety and depressive disorders, personality disorders) among idiopathc scoliosis patients compared to healthy controls. In addition, there are some reports, although more systematic research is warranted, on the role of mental health and personality traits in relation to the adherence to conservative treatment. Given the increasing role of surgical treatment in the management of scoliosis, as well as several reports on negative psychological outcomes of such interventions, there is a growing need for ongoing screening and mental health care in this population. It seems this also holds true for non-operative treatments, particularly bracing therapy. One should keep in mind that these scoliosis-psychopathology relations are deduced from a limited number of empirical studies, usually conducted on small sample sizes, suggesting the need for further large-scale investigations, preferrably those with longitudinal research designs. Understanding the complex interplay between personality/psychopathology and spinal deformities within the framework of personalized mind-body medicine, should help clinicians tailor more individualized and specific treatments and predict therapeutic outcomes in this clinical population.

Systematic review and meta-analysis of published prevalence of scoliosis among primary and middle school students in Mainland China. To evaluate the prevalence of scoliosis among primary and middle school students in Mainland China. There is substantial uncertainty regarding the prevalence of scoliosis in Mainland China among the primary and middle school students. We conducted a systematic review aiming to describe the prevalence of scoliosis in Mainland China. We systematically reviewed the published epidemiological studies or reports on the prevalence of scoliosis in Chinese cities. Scopus, PubMed, WanFang Database, CNKI, China National Science and Technology Digital Library, and WeiPu Database were searched for studies reporting a prevalence estimate for scoliosis in primary and middle school students. Meta-analyses were performed to estimate the pooled prevalence of scoliosis by STATA 12.0. Subgroup analyses were conducted according to the sex, age, and geographical area. A total of 38 articles, including 697,043 patients, were eligible for inclusion in this review. Meta-analyses revealed the prevalence of scoliosis to be 1.02% (95% [confidence interval] CI, 0.85-1.18) among the primary and middle school students in Mainland China. The female to male ratio was 1.54 (95% CI, 1.35-1.74; P < 0.001). According to the subgroup analysis by different ages, the prevalence of scoliosis increased from 0.73% (95% CI, 0.55-0.90) to 1.14% (95% CI, 0.86-1.42). Meta-analyses showed that the prevalence of scoliosis in Mainland China was 1.02% among the primary and middle school students. The prevalence of scoliosis in females was higher than in males and the ratio was 1.54. As they grew older, the prevalence of scoliosis increased in the students.

Bibliometric analysis. To apply the established technique of citation analysis to identify the 100 most influential articles in scoliosis surgery research published between 1900 and 2015. Previous studies have applied the technique of citation analysis to other areas of study. This is the first article to apply this technique to the field of scoliosis surgery. A two-step search of the Thomson Reuters Web of Science was conducted to identify all articles relevant to the field of scoliosis surgery. The top 100 articles with the most citations were identified based on analysis of titles and abstracts. Further statistical analysis was conducted to determine whether measures of author reputation and overall publication influence affected the rate at which publications were recognized and incorporated by other researchers in the field. Total citations for the final 100 publications included in the list ranged from 82 to 509. The period for publication ranged from 1954 to 2010. Most studies were published in the journal Spine (n = 63). The most frequently published topics of study were surgical techniques (n = 35) and outcomes (n = 35). Measures of author reputation (number of total studies in the top 100, number of first-author studies in the top 100) were found to have no effect on the rate at which studies were adopted by other researchers (number of years until first citation, and number of years until maximum citations). The number of citations/year a publication received was found to be negatively correlated with the rate at which it was adopted by other researchers, indicating that more influential manuscripts attained more rapid recognition by the scientific community at large. In assembling this publication, we have strived to identify and recognize the 100 most influential articles in scoliosis surgery research from 1900 to 2015. N/A.

We aimed to clarify the natural course of the progression of scoliosis and to identify scoliosis predictors. This was a retrospective, single-center, observational study. Total of 92 CP patients from Asahikawasou Ryouiku Iryou Center in Okayama, Japan were retrospectively analyzed. Cobb angle, presence of hip dislocation and pelvic obliquity, and Gross Motor Function Classification System (GMFCS) were investigated. Severe CP was defined as GMFCS level IV or V. The mean observation period was 10.7 years. Thirtyfour severe CP patients presented with scoliosis and were divided into 3 groups based on their clinical courses: severe, moderate and mild. The mean Cobb angles at the final follow-up were 129°, 53°, and 13° in the severe, moderate, and mild groups, respectively. The average progressions from 18 to 25 years were 2.7°/year, 0.7°/year, and 0.1°/year in the severe, moderate, and mild curve groups, respectively. We observed the natural course of scoliosis and identified 3 courses based on the Cobb angle at 15 and 18 years of age. This method of classification may help clinicians predict the patients' disease progression.

The effects of pelvic asymmetry and idiopathic scoliosis on postural balance during sitting were studied by measuring inclination angles, pressure distribution, and electromyography. Participants were classified into a control group, pelvic asymmetry group, scoliosis group, and scoliosis with pelvic asymmetry and then performed anterior, posterior, left, and right pelvic tilting while sitting on the unstable board for 5 seconds to assess their postural balance. Inclination and obliquity angles between the groups were measured by an accelerometer located on the unstable board. Pressure distribution (maximum force and peak pressure) was analyzed using a capacitive seat sensor. In addition, surface electrodes were attached to the abdominal and erector spinae muscles of each participant. Inclination and obliquity angles increased more asymmetrically in participants with both pelvic asymmetry and scoliosis than with pelvic asymmetry or scoliosis alone. Maximum forces and peak pressures of each group showed an asymmetrical pressure distribution caused by the difference in height between the left and right pelvis and curve type of the patients' spines when performing anterior, posterior, left, and right pelvic tilting while sitting. Muscle contraction patterns of external oblique, thoracic erector spinae, lumbar erector spinae, and lumbar multifidus muscles may be influenced by spine curve type and region of idiopathic scoliosis. Asymmetrical muscle activities were observed on the convex side of scoliotic patients and these muscle activity patterns were changed by the pelvic asymmetry. From these results, it was confirmed that pelvic asymmetry and idiopathic scoliosis cause postural asymmetry, unequal weight distribution, and muscular imbalance during sitting.

Core stabilization training is used to improve postural balance in musculoskeletal problems. The purpose of this study was to investigate the effectiveness of stabilization training in adolescent idiopathic scoliosis. A randomized controlled trial, pretest-posttest design. In total, 25 subjects with adolescent idiopathic scoliosis were randomly divided into two groups: stabilization group ( n = 12) and control group ( n = 13). The stabilization group received core stabilization in addition to traditional rehabilitation, and the control group received traditional rehabilitation for 10 weeks. Assessment included Cobb's angle on radiograph, apical vertebral rotation in Adam's test, trunk asymmetry (Posterior Trunk Symmetry Index), cosmetic trunk deformity (Trunk Appearance Perception Scale), and quality of life (Scoliosis Research Society-22 questionnaire). Inter-group comparisons showed significantly greater improvements in the mean change in lumbar apical vertebral rotation degree and the pain domain of Scoliosis Research Society-22 in the stabilization group than those in the control group ( p < 0.05). No significant differences were observed for other measurements between the groups; however, trends toward greater improvement were observed in the stabilization group. Core stabilization training in addition to traditional exercises was more effective than traditional exercises alone in the correction of vertebral rotation and reduction of pain in adolescent idiopathic scoliosis. Clinical relevance Stabilization exercises are more effective in reducing rotation deformity and pain than traditional exercises in the conservative rehabilitation of adolescent idiopathic scoliosis. These improvements suggest that stabilization training should be added to rehabilitation programs in adolescent idiopathic scoliosis.

A trial of brace therapy modified by a measured personality pattern of patients with idiopathic scoliosis was performed. To evaluate the effectiveness of performing personality tests for patients with idiopathic scoliosis who undergo brace therapy. Brace therapy has often been used for the treatment of scoliosis. However, emotional distress can result from this therapy. Few attempts have been made to reduce such stress. A test using the Maudsley Personality Inventory was performed on 145 adolescent females with idiopathic scoliosis, treated with brace therapy alone, before the start of brace therapy and 1 month after the start of brace therapy. On the basis of test results, the patients were rated as normal type and four abnormal types. Brace therapy was continued considering the personality pattern of patients. For all patients, changes in psychologic test results, compliance with braces wearing instructions, and correction of scoliosis were analyzed. Of the 134 patients rated as normal before the start of therapy, 108 patients were rated as abnormal pattern when tested 1 month after the start of therapy. After performing autogenic training for patients with E-N+ and E-N- personalities, and giving advice to school teachers to decrease the emotional stress for patients with E+N+ personality, 47 patients were finally rated as abnormal pattern. In total, 12 (8%) of the 145 patients dropped out. In dropouts, the average pretreatment deformity of 29 degrees (range: 21 degrees -37 degrees ) had increased to an average of 37 degrees (range, 31 degrees -48 degrees ). Psychologic tests may be useful and provide a means of modifying brace therapy tailored to the psychologic conditions of individual patients.

Spinal instrumentation and fusion for the treatment of scoliosis is primarily a mechanical intervention to correct the deformity and halt further progression. While implant-related complications remain a concern, little is known about the magnitudes of the forces applied to the spine during surgery, which may affect post-surgical outcomes. In this study, the compressive forces applied to each spinal segment during anterior instrumentation were measured in a series of patients with Adolescent Idiopathic Scoliosis. A force transducer was designed and retrofit to a routinely used surgical tool, and compressive forces applied to each segment during surgery were measured for 15 scoliosis patients. Cobb angle correction achieved by each force was measured on intra-operative fluoroscope images. Relative changes in orientation of the screw within the vertebra were also measured to detect intra-operative screw plough. Intra-operative forces were measured for a total of 95 spinal segments. The mean applied compressive force was 540N (SD 230N, range 88N-1019N). There was a clear trend for higher forces to be applied at segments toward the apex of the scoliosis. Fluoroscopic evidence of screw plough was detected at 10 segments (10.5%). The magnitude of forces applied during anterior scoliosis correction vary over a broad range. These forces do reach magnitudes capable of causing intra-operative vertebral body screw plough. Surgeons should be aware there is a risk for tissue overload during correction, however the clinical implications of intra-operative screw plough remain unclear. The dataset presented here is valuable for providing realistic input parameters for in silico surgical simulations. Copyright © 2016 Elsevier Ltd. All rights reserved.

Spinal Manipulative Therapy for Adolescent Idiopathic Scoliosis: A Systematic Review.

PubMed

Théroux, Jean; Stomski, Norman; Losco, Christine Dominique; Khadra, Christelle; Labelle, Hubert; Le May, Sylvie

The purpose of this study was to perform a systematic review of clinical trials of spinal manipulative therapy for adolescent idiopathic scoliosis. Search strategies were developed for PubMed, CINHAL, and CENTRAL databases. Studies were included through June 2016 if they were prospective trials that evaluated spinal manipulative therapy (eg, chiropractic, osteopathic, physical therapy) for adolescent idiopathic scoliosis. Data were extracted and assessed by 2 independent reviewers. Cochrane risk of bias tools were used to assess the quality of the included studies. Data were reported qualitatively because heterogeneity prevented statistical pooling. Four studies satisfied the inclusion criteria and were critically appraised. The findings of the included studies indicated that spinal manipulative therapy might be effective for preventing curve progression or reducing Cobb angle. However, the lack of controls and small sample sizes precluded robust estimation of the interventions' effect sizes. There is currently insufficient evidence to establish whether spinal manipulative therapy may be beneficial for adolescent idiopathic scoliosis. The results of the included studies suggest that spinal manipulative therapy may be a promising treatment, but these studies were all at substantial risk of bias. Further high-quality studies are warranted to conclusively determine if spinal manipulative therapy may be effective in the management of adolescent idiopathic scoliosis. Copyright © 2017.

This study clarifies the correlation between the components of the Scoliosis Research Society Outcomes Instrument (SRS-24) and the radiographic parameters after surgery in Japanese idiopathic scoliosis patients. To investigate the correlation between the magnitude of back deformity after scoliosis surgery and the components of the SRS-24. Patient outcomes for Japanese scoliosis patients using the SRS-24 have not been fully investigated. Idiopathic scoliosis patients (n = 81) who were treated with surgery and followed up for more than 2 years were evaluated. Radiographic examination included Cobb angle, rotation angle of apical vertebrae, and translation of the C7 vertebra from the center sacral line on the coronal plane. In addition, the score of one new question regarding postoperative scar was investigated and compared with that of the individual SRS-24 domains. A comparison of the SRS-24 and radiographic results revealed a significant inverse correlation between total pain and the postoperative correction of the rotation angle in the thoracic curve (rs = 0.27; P < 0.05). General self-image was inversely correlated with the Cobb angle (rs = -0.23; P < 0.05) and the rotation angle (rs = -0.30; P < 0.01) in the thoracic curve. Self-image after surgery was positively correlated with the correction degree of the thoracic Cobb angle (rs = 0.27; P < 0.05); 60% of patients had some concerns regarding postoperative scar, and the concerned patients demonstrated significantly lower scores in the pain and general self-image domains (P < 0.05) than the unconcerned patients did. Patients with a greater Cobb angle or rotation angle in the thoracic curve had a negative self-image. Self-image improved after surgery by greater correction of the thoracic Cobb angle. Thoracic scoliotic deformity with prominence should be substantially reduced by the surgical treatment to improve satisfaction rates and self-image regarding back appearance. Additionally, physicians should pay more

Screening programs to detect scoliosis in the adolescent population are active in most communities. Two percent of children screened will be referred for treatment or observation. Increasing concern has been voiced regarding the amount of the potential effects of the radiation administered in such screening programs. Radiation dosage was directly measured on 19 children participating in an established school scoliosis screening program, using lithium fluoride thermoluminescence dosimeters. The mean gonadal doses are measured to be 19 mrem in males and estimated at a maximum 95 mrem in females. The mean entrance skin dose was 174 mrem. A lack of uniformitymore » in the radiographic techniques employed by individual technician was identified. The measured doses were within established acceptable limits and are comparable or below the average dose of 100 mrem received annually by the general public from the environment.« less

Severe progressive scoliosis due to huge subcutaneous cavernous hemangioma: A case report

PubMed Central

2011-01-01

Cavernous hemangioma consists mainly of congenital vascular malformations present before birth and gradually increasing in size with skeletal growth. A small number of patients with cavernous hemangioma develop scoliosis, and surgical treatment for the scoliosis in such cases has not been reported to date. Here we report a 12-year-old male patient with severe progressive scoliosis due to a huge subcutaneous cavernous hemangioma, who underwent posterior correction and fusion surgery. Upon referral to our department, radiographs revealed a scoliosis of 85° at T6-L1 and a kyphosis of 58° at T4-T10. CT and MR images revealed a huge hemangioma extending from the subcutaneous region to the paraspinal muscles and the retroperitoneal space and invading the spinal canal. Posterior correction and fusion surgery using pedicle screws between T2 and L3 were performed. Massive hemorrhage from the hemangioma occurred during the surgery, with intraoperative blood loss reaching 2800 ml. The scoliosis was corrected to 59°, and the kyphosis to 45° after surgery. Seven hours after surgery, the patient suffered from hypovolemic shock and disseminated intravascular coagulation due to postoperative hemorrhage from the hemangioma. The patient developed sensory and conduction aphasia caused by cerebral hypoxia during the shock on the day of the surgery. At present, two years after the surgery, although the patient has completely recovered from the aphasia. This case illustrates that, in correction surgery for scoliosis due to huge subcutaneous cavernous hemangioma, intraoperative and postoperative intensive care for hemodynamics should be performed, since massive hemorrhage can occur during the postoperative period as well as the intraoperative period.

Concern about the amount of radiation received during scoliosis evaluation and treatment led us to measure radiation exposure in an anthropomorphic phantom to determine the increased risk of breast cancer in young women with scoliosis. Assuming that 22 radiographic examinations were performed over the course of scoliosis treatment, the increased relative risk of breast cancer was determined to be 0.22% in these patients.

Purpose Conversational topics chosen by a group of adults with degenerative cognitive-linguistic disorders for personalized communication board development were examined. The patient-generated themes commonly selected are presented to guide treatment planning and communication board development. Method Communication boards were created for 109 adults as part of a larger research project. One autobiographical topic that each participant would enjoy discussing multiple times was represented on each communication board with 16 pictures and word labels. For this review, topics were collapsed into general themes through a consensus process and examined by gender and age. Results Sixty unique conversational topics were identified from 109 participants and collapsed into 9 general themes: Hobbies, Family, Travel, Work, Home/Places I've Lived, Sports/Fitness, Religion, Animals, and World War II. Age and gender produced variations in themes chosen, though no significance in rank orders was found across groups. Conclusions Topics selected by adults with degenerative cognitive-linguistic disorders for communication boards resemble common conversational adult themes and do not center around basic needs or medical issues. Differences in gender and age for topic selection tend to be based on traditional roles. These general themes should be used when creating personalized communication boards for those who benefit from conversational aids. PMID:25835511

This preliminary study evaluates untreated Japanese patients with idiopathic scoliosis using the Scoliosis Research Society Outcomes Instrument (SRS-24). To determine the baseline patient outcome score using the SRS-24 for untreated Japanese scoliosis patients compared with a nonscoliosis group. The SRS instrument with 24 questions was developed to help evaluate patient-perceived outcomes of idiopathic scoliosis treatment. Evaluation of untreated Japanese idiopathic scoliosis patients using the SRS instrument has not been reported. Japanese idiopathic scoliosis patients (n = 141) (mean age, 13.6 years; range, 10-17 years) with a Cobb angle of more than 20 degrees who were not treated with a brace or surgery, were evaluated in comparison with a nonscoliosis group (healthy junior high school students; n = 72) using the SRS-24. The scoliosis group was categorized as mild deformity group with a major curve Cobb angle of less than 30 degrees, moderate deformity group with 30 degrees to 49 degrees, and severe deformity group with more than 50 degrees. The patients were evaluated using section 1 (15 questions) of the SRS-24, which was divided into four domains: total pain, general self-image, general function, and activity. Reliability, as determined by internal consistency, was validated using Cronbach's alpha for these domain scales. The severe deformity group had the lowest scores compared with the other deformity groups and the nonscoliosis group in pain (P < 0.0001) and self-image (P < 0.05) domains. The scores for questions 3 (P < 0.0001) and 5 (P < 0.0001), evaluation of self-image of back appearance, were significantly lower in the scoliosis group than those in the nonscoliosis group. This tendency was more significant in the patients with greater curve magnitude. Scores for questions 14 and 15, evaluation of general self-image, in the scoliosis group were, however, higher than those in the nonscoliosis group. Internal consistency using Cronbach's alpha was 0

ABSTRACT Objective: To evaluate the prevalence of scoliosis and the risk factors in elementary school students. Methods: A cross-sectional study was carried out in 954 students in 2015. The instrument involved was a questionnaire on postural habits, socioeconomic conditions, and demographic factors. The anthropometric measurements, including height and weight, a visual inspection of the deformity of the vertebral column, the leveling of shoulders, and the Adam’s test were obtained. The sample was calculated in the expected frequency of 12.3%, acceptable error rate of 2.0% and confidence level of 95.0%. To compare the proportions, the chi-square test or Fisher’s exact test was applied. The association between scoliosis and risk factors was evaluated by logistic regression, being significant p <0.05. Results: The prevalence of scoliosis was 24.3%, higher in obese patients and students who adopted a sitting position for a long period of time. Obese students showed a 1.8 times higher chance of testing positive Adam’s Forward Bend Test when compared to normal-weight/lean and 2.1 times higher chance compared to overweight students. The sitting position for watching television increases the chance of testing positive Adam’s test in 38.0%, when compared to the lying position. Obesity increases the risk of testing positive Adam’s test in 74.0 and 98.0%, when compared, respectively, to the underweight/normal weight and overweight. Conclusions: There was a high prevalence of scoliosis in students from public elementary schools in Santos. The most influential factors for this deviation of the spine were obesity and the position adopted by students to watch television. PMID:28977336

Purpose School screening allows for early detection and early treatment of scoliosis, with the purpose of reducing the number of patients requiring surgical treatment. Children between 10 and 14 years old are considered as good candidates for school screening tests of scoliosis. The purpose of the present study was to assess the epidemiological findings of idiopathic scoliosis in 11-year-old Korean adolescents. Materials and Methods A total of 37856 11-year-old adolescents were screened for scoliosis. There were 17110 girls and 20746 boys. Adolescents who were abnormal by Moiré topography were subsequently assessed by standardized clinical and radiological examinations. A scoliotic curve was defined as 10° or more. Results The prevalence of scoliosis was 0.19% and most of the curves were small (10° to 19°). The ratio of boys to girls was 1:5.5 overall. Sixty adolescents (84.5%) exhibited single curvature. Thoracolumbar curves were the most common type of curve identified, followed by thoracic and lumbar curves. Conclusion The prevalence of idiopathic scoliosis among 11-year-old Korean adolescents was 0.19%. PMID:24719147

In our centre, the postoperative scoliosis rehabilitation consists in stabilizing postural and respiratory exercises lasting several hours a day (5 1/2 to 7 hours). Additionally to pain treatment, we apply pain physiotherapy, physical therapy, acupuncture and besides manual medicine, also a psychological intervention and pain treatment by medication. 46 patients suffered from heavier pain 10 or more years after scoliosis surgery. The patients reported their pain at the beginning and at the end of 3-6 week in-patient rehabilitation programme. We applied a visual analogous scale (VAS), a numerical scale (NS), a standardized adjective scale (VRS), and a pain frequency scale. All the patients with an average age of 36 years old (SD=16) and an average curve angle of 35 degrees thoracic (SD=36) and 26 degrees lumbar (SD=22) showed a decrease of the values on the pain intensity scale. Pain reduction was highly significant, as well as pain frequency. Chronic pain as a late result following scoliosis surgery can be reduced by an intensive in-patient rehabilitation, at least in the short term. There are further necessary studies in order to follow-up the long-term effect of postoperative rehabilitation.

Degenerative lumbar scoliosis (DLS) is often associated with sagittal imbalance, which may affect patients' health outcomes before and after surgery. The appropriateness of surgery and preferred operative approaches has not been examined in detail for patients with DLS and sagittal imbalance. The goals of this article were to describe what is currently known about the relationship between sagittal imbalance and health outcomes among patients with DLS and to determine how indications for surgery in patients with DLS differ when sagittal imbalance is present. This study included a literature review and an expert panel using the RAND/University of California at Los Angeles (UCLA) Appropriateness Method. To develop appropriate use criteria for DLS, researchers at the RAND Corporation recently employed the RAND/UCLA Appropriateness Method, which involves a systematic review of the literature and multidisciplinary expert panel process. Experts reviewed a synopsis of published literature and rated the appropriateness of five common operative approaches for 260 different clinical scenarios. In the present work, we updated the literature review and compared panelists' ratings in scenarios where imbalance was present versus absent. This work was funded by the Collaborative Spine Research Foundation, a group of surgical specialty societies and device manufacturers. On the basis of 13 eligible studies that examined sagittal imbalance and outcomes in patients with DLS, imbalance was associated with worse functional status in the absence of surgery and worse symptoms and complications postoperatively. Panelists' ratings demonstrated a consistent pattern across the diverse clinical scenarios. In general, when imbalance was present, surgery was more likely to be appropriate or necessary, including in some situations where surgery would otherwise be inappropriate. For patients with moderate to severe symptoms and imbalance, a deformity correction procedure was usually appropriate

Conservative management of neuromuscular scoliosis: personal experience and review of literature.

The principles of conservative management of neuromuscular scoliosis in childhood and adolescence are presented. Analysis of personal experience and literature review. The topic is discussed separately for patients with flaccid or spastic paresis. These demonstrate that conservative management might be proposed for patients with neuromuscular scoliosis in many clinical situations. In spastic disorders, it maintains the symmetry around the hip joints. Bracing is technically difficult and often is not tolerated well by cerebral palsy children. In patients with flaccid paresis, the fitting and the use of brace is easier than in spastic patients. The flexibility of the spinal curvature is more important. Functional benefits of conservative management of neuromuscular scoliosis comprise stable sitting, easier use of upper limbs, discharge of the abdomen from the collapsing trunk, increased diaphragm excursion, and, not always, prevention of curve progression. Specific natural history and multiple medical problems associated with the disease make the treatment of children with neuromuscular scoliosis an extremely complex issue, best addressed when a team approach is applied. Continuously improving techniques of conservative management, comprising bracing and physiotherapy, together with correctly timed surgery incorporated in the process of rehabilitation, provide the optimal care for patients.

Prospective observational cohort study with matched and unmatched comparisons. Level II evidence. The purpose of this study is to compare results of adult symptomatic lumbar scoliosis (ASLS) patients treated nonoperatively and operatively. This is an evidence-based prospective multicenter study to answer the question of whether nonoperative and operative treatment improves the quality of life (QOL) in these patients at 2-year follow-up. Only 1 paper in the peer-reviewed published data directly addresses this question. That paper suggested that operative treatment was more beneficial than nonoperative care, but the limitations relate to historical context (all patients treated with Harrington implants) and the absence of validated patient-reported QOL (QOL) data. This study assesses 160 consecutively enrolled patients (ages 40-80 years) with baseline and 2-year follow-up data from 5 centers. Lumbar scoliosis without prior surgical treatment was defined as a minimum Cobb angle of 30 degrees (mean: 54 degrees for patients in this study). All patients had either an Oswestry Disability Index (ODI) score of 20 or more (mean: 33) or Scoliosis Research Society (SRS) domain scores of 4 or less in pain, function, and self-image (mean: 3.2) at baseline. Pretreatment and 2-year follow-up data collected prospectively included basic radiographic parameters, complications and SRS QOL, ODI, and Numerical Rating Scale back and leg pain scores. At 2 years, follow-up on the operative patients was 95% and for the nonoperative patients it was 45%. The demographics for the nonoperative patients who were followed up for 2 years versus those who were lost to follow-up were identical. The operative cohort significantly improved in all QOL measures. The nonoperative cohort did not improve and nonsignificant decline in QOL scores was common. At minimum 2-year follow-up, operative patients outperformed nonoperative patients by all measures. It would appear from this study that common

This study aimed to identify and describe the experience of parents of children diagnosed with early onset scoliosis living in Australia. Chronic childhood disease has a major impact on health-related quality of life. Caring for a child with a chronic illness is well documented but the specific experiences of parents who care for children with early onset scoliosis, a rare but devastating illness, has not been explored. Numerous studies have described the interrelated psychological, financial, social, physical and logistical factors that impact the experience of the caregiver role with various diseases, but in the case of early onset scoliosis, limited studies have been conducted about the parental experience. A qualitative descriptive design was used. A snowball sampling technique assisted in the recruitment. Parents invited to the study included mothers, fathers and guardians. Data were collected through semistructured interviews and transcribed verbatim. Transcripts were analysed thematically. Data collection complied with the Consolidated criteria for reporting qualitative research guidelines. Twelve mothers of children with early onset scoliosis were interviewed, as only mothers consented to participate. Four major themes emerged: emotional rollercoaster ride, a lack of resources, money talks and pervasive burden. Factors that impacted on the participants' ability to confront, manage and endure caring for a child with early onset scoliosis emerged from the data. The findings suggest there are multiple factors that influence the experience of mothers' caring for a child with early onset scoliosis. The recognition and appropriate management of these factors by healthcare professionals have the potential to improve the quality of life of parents who care for a child with early onset scoliosis. Healthcare professionals have first-line contact with parents of children with early onset scoliosis and are well placed to provide parents with evidence-based education

Longer survival for children with sarcoma has led to the recognition of chronic health conditions related to prior therapy. We sought to study the association of sarcoma therapy with the development of scoliosis. We reviewed patient demographics, treatment exposures, and functional outcomes for patients surviving >10 years after treatment for sarcoma between 1964 and 2002 at our institution. The diagnosis of scoliosis was determined by imaging. Functional performance and standardized questionnaires were completed in a long-term follow-up clinic. We identified 367 patients, with median age at follow-up of 33.1 years. Scoliosis was identified in 100 (27.2%) patients. Chest radiation (relative risk (RR), 1.88 (95% confidence interval (CI), 1.21-2.92), p < 0.005) and rib resection (RR, 2.64 (CI, 1.79-3.89), p < 0.0001) were associated with an increased incidence of scoliosis; thoracotomy without rib resection was not. Of 21 patients who underwent rib resection, 16 (80.8%) had the apex of scoliosis towards the surgical side. Scoliosis was associated with worse pulmonary function (RR, 1.74 (CI, 1.14-2.66), p < 0.01) and self-reported health outcomes, including functional impairment (RR, 1.60 (CI, 1.07-2.38), p < 0.05) and cancer-related pain (RR, 1.55 (CI, 1.11-2.16), p < 0.01). Interestingly, pulmonary function was not associated with performance on the 6-min walk test in this young population. Children with sarcoma are at risk of developing scoliosis when treatment regimens include chest radiation or rib resection. Identification of these risk factors may allow for early intervention designed to prevent adverse long-term outcomes. Cancer survivors at risk of developing scoliosis may benefit from monitoring of pulmonary status and early physical therapy.

The aim of this study was a quantitative analysis of a surgeon's learning curve for scoliosis surgery and the relationship between the surgeon's experience and post-operative outcomes, which has not been previously well described. We have investigated the operating time as a function of the number of patients to determine a specific pattern; we analysed factors affecting the operating time and compared intra- and post-operative outcomes. We analysed 47 consecutive patients undergoing scoliosis surgery performed by a single, non-trained scoliosis surgeon. Operating time was recorded for each of the four parts of the procedures: dissection, placement of pedicle screws, reduction of the deformity and wound closure. The median operating time was 310 minutes (interquartile range 277.5 to 432.5). The pattern showed a continuous decreasing trend in operating time until the patient number reached 23 to 25, after which it stabilised with fewer patient-dependent changes. The operating time was more affected by the patient number (r =- 0.75) than the number of levels fused (r = 0.59). Blood loss (p = 0.016) and length of stay in hospital (p = 0.012) were significantly less after the operating time stabilised. Post-operative functional outcome scores and the rate of complications showed no significant differences. We describe a detailed learning curve for scoliosis surgery based on a single surgeon's practise, providing useful information for novice scoliosis surgeons and for those responsible for training in spinal surgery.

Rate of complications in scoliosis surgery - a systematic review of the Pub Med literature.

Weiss, Hans-Rudolf; Goodall, Deborah

Spinal fusion surgery is currently recommended when curve magnitude exceeds 40-45 degrees. Early attempts at spinal fusion surgery which were aimed to leave the patients with a mild residual deformity, failed to meet such expectations. These aims have since been revised to the more modest goals of preventing progression, restoring 'acceptability' of the clinical deformity and reducing curvature.In view of the fact that there is no evidence that health related signs and symptoms of scoliosis can be altered by spinal fusion in the long-term, a clear medical indication for this treatment cannot be derived. Knowledge concerning the rate of complications of scoliosis surgery may enable us to establish a cost/benefit relation of this intervention and to improve the standard of the information and advice given to patients. It is also hoped that this study will help to answer questions in relation to the limiting choice between the risks of surgery and the "wait and see - observation only until surgery might be recommended", strategy widely used. The purpose of this review is to present the actual data available on the rate of complications in scoliosis surgery. Search strategy for identification of studies; Pub Med and the SOSORT scoliosis library, limited to English language and bibliographies of all reviewed articles. The search strategy included the terms; 'scoliosis'; 'rate of complications'; 'spine surgery'; 'scoliosis surgery'; 'spondylodesis'; 'spinal instrumentation' and 'spine fusion'. The electronic search carried out on the 1st February 2008 with the key words "scoliosis", "surgery", "complications" revealed 2590 titles, which not necessarily attributed to our quest for the term "rate of complications". 287 titles were found when the term "rate of complications" was used as a key word. Rates of complication varied between 0 and 89% depending on the aetiology of the entity investigated. Long-term rates of complications have not yet been reported upon. Scoliosis

A retrospective examination was performed to assess the accuracy of metrizamide myelography (MM) and computed tomographic metrizamide myelography (CTMM) in scoliosis. Of 81 consecutive scoliotic children studied by myelography, 30 had only MM while the remaining 51 had CTMM immediately afterward. CTMM added esential diagnostic information in 13 cases of dysraphism and 4 cases, both methods gave the same imformation. The outhors conclude that in patients with severe scoliosis, dysraphism, and scoliosis with localized neurological disturbances, CTMM should always be added to MM or be the only examination; while in idiopathic scoliosis with vague neurological disturbances a survey of themore » entire spine is essential, preferably with MM.« less

Background Vertebral wedging is associated with spinal deformity progression in adolescent idiopathic scoliosis. Reporting frontal and sagittal wedging separately could be misleading since these are projected values of a single three-dimensional deformation of the vertebral body. The objectives of this study were to determine if three-dimensional vertebral body wedging is present in mild scoliosis and if there are a preferential vertebral level, position and plane of deformation with increasing scoliotic severity. Methodology Twenty-seven adolescent idiopathic scoliotic girls with mild to moderate Cobb angles (10° to 50°) participated in this study. All subjects had at least one set of bi-planar radiographs taken with the EOS® X-ray imaging system prior to any treatment. Subjects were divided into two groups, separating the mild (under 20°) from the moderate (20° and over) spinal scoliotic deformities. Wedging was calculated in three different geometric planes with respect to the smallest edge of the vertebral body. Results Factorial analyses of variance revealed a main effect for the scoliosis severity but no main effect of vertebral Levels (apex and each of the three vertebrae above and below it) (F = 1.78, p = 0.101). Main effects of vertebral Positions (apex and above or below it) (F = 4.20, p = 0.015) and wedging Planes (F = 34.36, p<0.001) were also noted. Post-hoc analysis demonstrated a greater wedging in the inferior group of vertebrae (3.6°) than the superior group (2.9°, p = 0.019) and a significantly greater wedging (p≤0.03) along the sagittal plane (4.3°). Conclusions Vertebral wedging was present in mild scoliosis and increased as the scoliosis progressed. The greater wedging of the inferior group of vertebrae could be important in estimating the most distal vertebral segment to be restrained by bracing or to be fused in surgery. Largest vertebral body wedging values obtained in the sagittal plane support the claim

Background and purpose Knee arthroscopy is commonly performed to treat degenerative knee disease symptoms and traumatic meniscal tears. We evaluated whether the recent high-quality randomized control trials not favoring arthroscopic surgery for degenerative knee disease affected the procedure incidence and trends in Finland and Sweden. Patients and methods We conducted a bi-national registry-based study including all adult (aged ≥18 years) inpatient and outpatient arthroscopic surgeries performed for degenerative knee disease (osteoarthritis (OA) and degenerative meniscal tears) and traumatic meniscal tears in Finland between 1997 and 2012, and in Sweden between 2001 and 2012. Results In Finland, the annual number of operations was 16,389 in 1997, reached 20,432 in 2007, and declined to 15,018 in 2012. In Sweden, the number of operations was 9,944 in 2001, reached 11,711 in 2008, and declined to 8,114 in 2012. The knee arthroscopy incidence for OA was 124 per 105 person-years in 2012 in Finland and it was 51 in Sweden. The incidence of knee arthroscopies for meniscal tears coded as traumatic steadily increased in Finland from 64 per 105 person-years in 1997 to 97 per 105 person-years in 2012, but not in Sweden. Interpretation The incidence of arthroscopies for degenerative knee disease declined after 2008 in both countries. Remarkably, the incidence of arthroscopy for degenerative knee disease and traumatic meniscal tears is 2 to 4 times higher in Finland than in Sweden. Efficient implementation of new high-quality evidence in clinical practice could reduce the number of ineffective surgeries. PMID:26122621

Stem cell therapies are being explored extensively as treatments for degenerative eye disease, either for replacing lost neurons, restoring neural circuits or, based on more recent evidence, as paracrine-mediated therapies in which stem cell-derived trophic factors protect compromised endogenous retinal neurons from death and induce the growth of new connections. Retinal progenitor phenotypes induced from embryonic stem cells/induced pluripotent stem cells (ESCs/iPSCs) and endogenous retinal stem cells may replace lost photoreceptors and retinal pigment epithelial (RPE) cells and restore vision in the diseased eye, whereas treatment of injured retinal ganglion cells (RGCs) has so far been reliant on mesenchymal stem cells (MSC). Here, we review the properties of non-retinal-derived adult stem cells, in particular neural stem cells (NSCs), MSC derived from bone marrow (BMSC), adipose tissues (ADSC) and dental pulp (DPSC), together with ESC/iPSC and discuss and compare their potential advantages as therapies designed to provide trophic support, repair and replacement of retinal neurons, RPE and glia in degenerative retinal diseases. We conclude that ESCs/iPSCs have the potential to replace lost retinal cells, whereas MSC may be a useful source of paracrine factors that protect RGC and stimulate regeneration of their axons in the optic nerve in degenerate eye disease. NSC may have potential as both a source of replacement cells and also as mediators of paracrine treatment. Copyright © 2015. Published by Elsevier B.V.

School scoliosis screening has been carried out around the world. The screen program has never been performed on Chongming Island, the third largest island in China and characterized less population exchange with the rest of China. This study was designed to examine scoliotic parameters in children from Chongming Island and determine whether the parameters differed from those of the published data. A total of 6824 children (3477 boys and 3347 girls) aged from 6 to 17 were recruited. The screen included Adam's test and scoliometer measurements. Posteroanterior radiographic evaluation was performed if trunk rotation was 5° or more. One hundred seventy two were confirmed with Cobb angle of 10° or more; the prevalence was 2.52 %, higher in girls (3.11 %) than in boys (1.96 %) (p < 0.05). There was a weak positive correlation between prevalence and age. Majority curves were minor (from 10 to 19°). The most common thoracic curve was right curve (60.3 % of all thoracic curves), while the most common thoracolumbar (75.5 %) and lumbar curves (64.7 %) were left curves. The prevalence of scoliosis on Chongming Island was 2.52 %. This study indicates that epidemiology of scoliosis has regional variation, and genetic differences may contribute such difference.

A clinical and radiological study of upper and lower limb joints was carried out on 25 experienced weight-lifters to identify the extent of degenerative joint disease (Osteoarthrosis) produced by this sport. Although significant degenerative changes were found in five lifters (20%). This figure is not greater than that found in the general population within the age group studied. There were more degenerative changes found in Olympic style weight-lifters (30.7%) than in power lifters (8.3%). The significance of these figures is discussed. The upper limb joints were almost completely free of degenerative changes. Images p97-a p97-b PMID:7407459

Torsional deformity of apical vertebra in adolescent idiopathic scoliosis.

Kotwicki, Tomasz; Napiontek, Marek

2002-01-01

CT scans of structural thoracic idiopathic scoliosis were reviewed in nine patients admitted to our department for scoliosis surgery. The apical vertebra scans were chosen and the following parameters were evaluated: 1) alpha angle formed by the axis of vertebra and the axis of spinous process 2) beta concave and beta convex angle between the spinous process and the left and right transverse process, respectively, 3) gamma concave and gamma convex angle between the axis of vertebra and the left and right transverse process, respectively, 4) the rotation angle to the sagittal plane. The constant deviation of the spinous process towards the convex side of the curve was observed. The vertebral body itself was distorted towards the concavity of the curve. The angle between the spinous process and the transverse process was smaller on the convex side of the curve. The torsional, intravertebral deformity of the apical vertebra was a factor acting in the direction opposite to the rotation, in the sense to reduce the deformity of the spine in idiopathic scoliosis.

A comparative study. To report a preliminary evaluation of the Scoliosis Research Society Outcomes Instrument (SRS-24) and determine whether differences in baseline scores exist between American and Japanese patients with idiopathic scoliosis. Because the SRS outcomes instrument was primarily introduced for the American population, baseline scores in the Japanese population might differ from the American population. A comparative study using the SRS instrument between American and Japanese patients with idiopathic scoliosis has not been reported. Two comparable groups of 100 idiopathic scoliosis patients before spinal fusion were separated into American (A) and Japanese (J). There were no statistically significant differences between the groups for gender (A: 9 men/91 women vs. J: 13 men/87 women), age (A: 15.0 +/- 2.4 vs. J: 14.9 +/- 3.8), main curve location (A: 77 thoracic/23 lumbar, J: 76 thoracic/24 lumbar), main curve Cobb angle (A: 50.5 +/- 5.2 vs. J: 51.1 +/- 8.7), and thoracic kyphosis (A: 20.9 +/- 14.3 vs. J: 19.9 +/- 12.1) (P > 0.05, for all comparisons). Patients were evaluated using the first section of the SRS-24 which was divided into 4 domains: total pain, general self-image, general function, and activity. SRS-24 scores were statistical compared in individual domains and questions using the Mann-Whitney U test. American patients had significantly lower scores in pain (P < 0.0001, A: 3.7 +/- 0.8 vs. J: 4.3 +/- 0.4), function (P < 0.01, A: 3.9 +/- 0.6 vs. J: 4.2 +/- 0.5), and activity (P < 0.0001, A: 4.5 +/- 0.8 vs. J: 4.9 +/- 0.3) domains compared with Japanese patients. Japanese patients had significantly lower scores in the self-image (P < 0.0001, A: 4.0 +/- 0.7 vs. J: 3.5 +/- 0.5) domain. With regard to individual questions, there were significant differences in the scores between the 2 groups for all questions except 5 and 13 (P < 0.05, for all comparisons). SRS-24 scores in the Japanese idiopathic scoliosis population differed from that of the

A cross-sectional observational study to determine the response distribution, internal consistency, and construct, concurrent, and discriminative validities of The Scoliosis Research Society-22 (SRS-22) Patient Questionnaire translated into Japanese as compared with the other language versions. To validate the Japanese version of SRS22. The SRS-22 was translated into several languages but yet not into Japanese. The Japanese SRS-22 and Medical Outcomes Study Short Form 36 were simultaneously administered to 114 adolescent idiopathic scoliosis patients. Exploratory factor analysis revealed a 4-factor structure, though several items were not loaded as theoretically expected. The originally constructed Japanese SRS-22 subscales and the English version showed similar response distribution. Internal consistency was fair but lower than that of the English version. The concurrent validity of the translated version, except for the self-image subscale, was supported using Medical Outcomes Study Short Form 36 subscales as a reference. The function scale differed significantly by curve angle magnitude and treatment status. The self-image score was the highest in patients under observation when curve angle was < 40 degrees, while postsurgical patients marked the highest scores when the angle > or = 40 degrees, respectively. The Japanese SRS-22 is valid and may be useful for clinical evaluation of Japanese scoliosis patients, though the self-image subscale may need further assessment.

This study aims to identify the risk factors leading to the development of severe scoliosis among children with cerebral palsy. A cross-sectional descriptive study of 70 children (aged 12-18 years) with severe spastic and/or dystonic cerebral palsy treated in a single specialist unit is described. Statistical analysis included Fisher exact test and logistic regression analysis to identify risk factors. Severe scoliosis is more likely to occur in patients with intractable epilepsy ( P = .008), poor gross motor functional assessment scores ( P = .018), limb spasticity ( P = .045), a history of previous hip surgery ( P = .048), and nonambulatory patients ( P = .013). Logistic regression model confirms the major risk factors are previous hip surgery ( P = .001), moderate to severe epilepsy ( P = .007), and female gender ( P = .03). History of previous hip surgery, intractable epilepsy, and female gender are predictors of developing severe scoliosis in children with cerebral palsy. This knowledge should aid in the early diagnosis of scoliosis and timely referral to specialist services.

Clinical study with pre- and postoperative back photographs and postoperative Scoliosis Research Society-22 survey in patients who had undergone surgery for idiopathic scoliosis. To determine the effect of showing patients their photographs before and after surgery for idiopathic scoliosis on postoperative patient satisfaction. After scoliosis surgery, patient satisfaction may be limited because the patients cannot directly see their back and may forget the preoperative appearance. In 60 patients who had undergone surgery for correction of idiopathic scoliosis (Lenke type 1), pre- and postoperative photographs were taken from the anterior, posterior, and right and left lateral views. After surgery, patients in group 1 (30 patients) were shown the preoperative and most recent follow-up photographs, and patients in group 2 (30 patients) had routine evaluation but were not shown their photographs. All patients completed the Scoliosis Research Society-22 survey. Patients in both groups had similar age, sex, distribution of Lenke type and Risser sign, follow-up, and pre- and postoperative Cobb angles and balance (coronal and sagittal). A significant difference was observed between the groups for survey question 10 (which was about self-image), question 18 (which was about function and activity), and question 21 (which was about satisfaction) (P ≤ 0.05). There were no differences between patients in groups 1 and 2 in Scoliosis Research Society-22 domain or total scores. By showing patients the pre- and postoperative clinical photographs, patient satisfaction may be greater, as measured with some SRS-22 scores. This method may enable clinicians to positively change the patients' self-image perception after surgery for correction of scoliosis. 4.

There are many factors influencing postoperative health-related quality of life of adolescent idiopathic scoliosis patients, including the degree of the deformity, culture, differences in geography, rural versus urban living environments, and social factors. The objective of this study was to analyze the significance of geographic factors and their differences influencing the postoperative quality of life in females with adolescent idiopathic scoliosis residing in urban and rural environments, by use of the Polish version of the SRS-24 questionnaire. Forty urban and 20 rural postoperative patients with adolescent scoliosis with a minimum 2-year follow-up period after surgery were included in the study. The process of cross-cultural adaptation was performed according to the IQOLA Project. General results of the Polish SRS-24 equalled 4.1 (SD 0.5) and 4.0 (SD.0.5) in the rural and urban groups of patients, respectively. The 2 groups do not differ in incidence of floor and ceiling effects. The Cronbach's alpha values are excellent for the general result of SRS-24 in urban and rural groups (0.85 and 0.85, respectively). The sub-groups differed significantly in the self-image after surgery domain (p=0.048). Patients from the rural group scored higher in the self-image after surgery domain but reported higher pain levels when compared to urban patients. The associations between SRS-24 results and radiographic parameters in the rural group of patients were strong, compared with moderate relations reported in the urban group.

Early-onset scoliosis is a heterogeneous condition, with highly variable manifestations and natural history. No standardized classification system exists to describe and group patients, to guide optimal care, or to prognosticate outcomes within this population. A classification system for early-onset scoliosis is thus a necessary prerequisite to the timely evolution of care of these patients. Fifteen experienced surgeons participated in a nominal group technique designed to achieve a consensus-based classification system for early-onset scoliosis. A comprehensive list of factors important in managing early-onset scoliosis was generated using a standardized literature review, semi-structured interviews, and open forum discussion. Three group meetings and two rounds of surveying guided the selection of classification components, subgroupings, and cut-points. Initial validation of the system was conducted using an interobserver reliability assessment based on the classification of a series of thirty cases. Nominal group technique was used to identify three core variables (major curve angle, etiology, and kyphosis) with high group content validity scores. Age and curve progression ranked slightly lower. Participants evaluated the cases of thirty patients with early-onset scoliosis for reliability testing. The mean kappa value for etiology (0.64) was substantial, while the mean kappa values for major curve angle (0.95) and kyphosis (0.93) indicated almost perfect agreement. The final classification consisted of a continuous age prefix, etiology (congenital or structural, neuromuscular, syndromic, and idiopathic), major curve angle (1, 2, 3, or 4), and kyphosis (-, N, or +) variables, and an optional progression modifier (P0, P1, or P2). Utilizing formal consensus-building methods in a large group of surgeons experienced in treating early-onset scoliosis, a novel classification system for early-onset scoliosis was developed with all core components demonstrating

Retrospective study of a series of 226 consecutive Chinese patients with congenital scoliosis. To identify the incidence of intraspinal abnormalities and other organ defects in surgical patients with congenital scoliosis in Chinese population. Previous studies have revealed high rates of intraspinal anomalies and other organ defects in patients with congenital scoliosis. The incidence of abnormalities in patients with congenital scoliosis in Chinese population has not been reported. A total of 226 patients with congenital scoliosis underwent surgical treatment in Peking Union Medical College Hospital between January 2005 and March 2011 were identified. A definitive diagnosis of congenital scoliosis for all patients was made. Complete data were reviewed, including medical records, plain radiograph, magnetic resonance (MR) image of the whole spine, echocardiography, and renal ultrasound. The incidence of intraspinal abnormalities and other organ defects were analyzed. Intraspinal abnormalities were found in 99 (43%) patients. Diastematomyelia was identified to be the most common intraspinal pathological anomaly, which was different from the previous reports. The incidence of intraspinal anomaly in patients with failures of segmentation and mixed defects were significantly higher than those with failures of formation. Patients with thoracic hemivertebrae were found to have a higher incidence of intraspinal abnormalities than patients with lumbar hemivertebrae. Patients with intraspinal abnormality had a higher incidence of positive clinical findings than those with normal magnetic resonance imaging. However, the difference between the 2 groups was not statistically significant. Other organic defects were found in 91(40%) patients. Cardiac defects were detected in 18%, urogenital anomalies in 12%, and gastrointestinal anomalies in 5% of the patients in this study. Diastematomyelia was found to be the most common intraspinal pathological anomaly and cardiac defects were

Spinopelvic fixation is an integral part of achieving solid fusion across the lumbosacral junction, especially in deformity procedures requiring substantial correction or long-segment constructs. Traditional S2-alar-iliac (S2AI) screw-placement techniques utilize fluoroscopy, increasing operative time and radiation exposure to the patient and surgeon. We describe a novel free-hand technique for S2AI screw placement in patients with adult spinal deformity. We reviewed the records of 45 consecutive patients who underwent spinopelvic fixation performed with use of S2AI screws by the senior surgeon and various fellows or residents over a 12-month period (2015 to 2016). In each case, the S2AI screws were placed utilizing a free-hand technique without fluoroscopic or image guidance. Screw position and accuracy were assessed by intraoperative O-arm imaging and analyzed using 3-dimensional interactive manipulation of computed tomography images. A total of 100 screws were placed, 51 by the senior surgeon and 49 by trainees. The mean patient age was 57.4 ± 12.7 years at the time of surgery; 37 (82.2%) of the patients were female. Preoperative diagnoses included adult idiopathic scoliosis (n = 19), adult degenerative scoliosis (n = 15), flatback syndrome (n = 2), fixed sagittal imbalance (n = 6), and distal junctional kyphosis (n = 3). Five (5%) of the screws were placed with moderate to severe cortical breaches, all of which perforated the pelvis posteriorly, with no clinically notable neurovascular or visceral complications. The breach rate did not differ significantly between the senior surgeon and trainees. The free-hand technique for S2AI screw placement, when performed in a standardized manner, was demonstrated to be safe and reliable in constructs requiring spinopelvic fixation. The accuracy of screw placement relies on visible and palpable anatomic landmarks that obviate the need for intraoperative fluoroscopy or image guidance, potentially reducing operative time

The relationship between thoracic deformity in scoliosis and lung function is poorly understood. In a pilot study, we reviewed computed tomography (CT) routine scans of patients undergoing scoliosis surgery. The CT scans were processed to segment the anatomy of the airways, lung and spine. A three-dimensional model was created to study the anatomical relationship. Preliminary analysis showed significant airway morphological differences depending on the anterior position of the spine. A computational fluid dynamics (CFD) study was also conducted on the airway geometry using the inspiratory scans. The CFD model assuming non-compliant airway walls was capable of showing pressure drops in areas of high airway resistance, but was unable to predict regional ventilation differences. Our results indicate a dependence between the dynamic deformation of the airway during breathing and lung function. Dynamic structural deformation must therefore be incorporated within any modelling approaches to guide clinicians on the decision to perform surgical correction of the scoliosis.

A cross-sectional analysis. The aim of this study was to determine whether the surgical treatment for scoliosis due to Duchenne muscular dystrophy (DMD) has decreased over a recent 11-year period, specifically, after the wide acceptance of glucocorticoid treatment for DMD. DMD can result in a flaccid neuromuscular scoliosis that has been traditionally treated surgically. In 2004, a comparative study demonstrated that glucocorticoid treatment decreased the progression of scoliosis in DMD. We used the Nationwide Inpatient Sample from 2001 to 2012 to identify patients with DMD undergoing spinal fusion. Demographic information (age, hospital size, location, geographic status) was collected. We examined the distribution of patient and hospital characteristics among cohorts undergoing spinal fusion from 2001 to 2004 (period 1; before publication of the comparative study), 2005 to 2008 (period 2; immediately following publication of the comparative study), and 2009 to 2012 (period 3; moderate duration following publication of the comparative study). We identified 1874 males undergoing spinal fusion. During this period, the overall rate of DMD surgeries declined by 48%-from 1.87 surgeries in 2001 to 0.97 surgeries in 2012 per million US males per year. This decline was significantly pronounced following the publication of the comparative study [periods 2 and 3; For period 2 vs. period 1: incidence rate ratio (IRR) = 0.71, 95% confidence interval (95% CI) = 0.56-0.91, P = 0.01; For period 3 vs. period 1: IRR = 0.77, 95% CI = 0.61-0.97, P = 0.03]. Our study demonstrates a significant decrease in the rate of scoliosis surgery for DMD from 2001 to 2012. It appears that the decline in surgical treatment could be related to the publication and landmark study demonstrating decreased progression of scoliosis with glucocorticoid treatment. 3.

Healthcare providers have limited time to spend with scoliosis patients who are considering surgery and their families. The purpose of this study was to evaluate an e-health strategy to increase knowledge and coping in patients with scoliosis who are surgical candidates and their families. We enrolled patients with scoliosis who were candidates for surgery and their families. Patients and their families completed the scoliosis knowledge questionnaire, meaning of illness questionnaire, social support and coping questionnaires before and after access to a comprehensive evidence-based scoliosis website ( http://www.aboutkidshealth.ca/scoliosis ). Seventy-four patients and 71 parents completed the evaluation. While both patients and parents improved their knowledge of scoliosis (p = 0.001 and p = 0.003, respectively), the scores of patients were consistently lower than those of the parents both before and after website use (p = 0.0001). Only parents demonstrated a change in the meaning of illness questionnaire, with a small increase in the negative attitude towards illness and a small decrease in the positive attitude towards illness (p = 0002 and p = 0.01, respectively). Of the 12 coping methods examined on the Adolescent Coping Orientation for Problem Experiences (A-COPE) instrument, patients were slightly more likely than parents to use relaxing and solving family problems as tools to cope following website access (p = 0.02 and p = 0.09, respectively). Parents demonstrated no significant changes in the four methods of coping on the Coping Health Inventory for Parents (CHIP) after website exposure. While the majority of patients and parents reported receiving sufficient support, over half of the patients indicated a need for more support in social participation. An evidence-based website increased the knowledge of patients and parents but simply providing access to the website had minimal impact on their coping and perceptions of social support. The

Rate of complications in scoliosis surgery – a systematic review of the Pub Med literature

Weiss, Hans-Rudolf; Goodall, Deborah

2008-01-01

Background Spinal fusion surgery is currently recommended when curve magnitude exceeds 40–45 degrees. Early attempts at spinal fusion surgery which were aimed to leave the patients with a mild residual deformity, failed to meet such expectations. These aims have since been revised to the more modest goals of preventing progression, restoring 'acceptability' of the clinical deformity and reducing curvature. In view of the fact that there is no evidence that health related signs and symptoms of scoliosis can be altered by spinal fusion in the long-term, a clear medical indication for this treatment cannot be derived. Knowledge concerning the rate of complications of scoliosis surgery may enable us to establish a cost/benefit relation of this intervention and to improve the standard of the information and advice given to patients. It is also hoped that this study will help to answer questions in relation to the limiting choice between the risks of surgery and the "wait and see – observation only until surgery might be recommended", strategy widely used. The purpose of this review is to present the actual data available on the rate of complications in scoliosis surgery. Materials and methods Search strategy for identification of studies; Pub Med and the SOSORT scoliosis library, limited to English language and bibliographies of all reviewed articles. The search strategy included the terms; 'scoliosis'; 'rate of complications'; 'spine surgery'; 'scoliosis surgery'; 'spondylodesis'; 'spinal instrumentation' and 'spine fusion'. Results The electronic search carried out on the 1st February 2008 with the key words "scoliosis", "surgery", "complications" revealed 2590 titles, which not necessarily attributed to our quest for the term "rate of complications". 287 titles were found when the term "rate of complications" was used as a key word. Rates of complication varied between 0 and 89% depending on the aetiology of the entity investigated. Long-term rates of

As in other fields of medicine, there is an increasing interest among orthopedic surgeons to measure health-related quality of life in adolescent idiopathic scoliosis patients and to evaluate the burden of disease and the effectiveness of different treatment strategies. The development of the revised Scoliosis Research Society 22-item patient questionnaire (SRS-22r) enabled a comprehensive evaluation of health-related quality of life of these patients. Over the years, the SRS-22r gained wide acceptance and has been used in several different countries, languages, and cultures. The SRS-22r has not been translated into Dutch to date. To translate the SRS-22r into Dutch and adapt it cross-culturally as outlined by international guidelines and to test its psychometric properties to measure health-related quality of life of adolescent idiopathic scoliosis patients in the Netherlands. A cross-sectional, multicenter validation study. A total of 135 adolescent idiopathic scoliosis patients (mean age 15.1 years old) of three major scoliosis centers in the Netherlands were enrolled in this study. Ninety-two (68%) subjects completed the Dutch SRS-22r, Child Health Questionnaire (CHQ)-CF87 (golden standard for adolescents), and Short Form (SF)-36 (golden standard for adults). Two weeks later, 73 (79%) of 92 respondents returned a second SRS-22r. Demographics, curve type, Risser stage, and treatment status were documented. Floor and ceiling effects, internal consistency, reproducibility, concurrent validity, and discriminative ability of the Dutch version of the SRS-22r questionnaire. For content analysis, SRS-22r domain scores (function, pain, self-image, mental health, and satisfaction with management) were explored and floor and ceiling effects were determined. Cronbach's α was calculated for internal consistency of each domain of the questionnaires and reproducibility was assessed by test-retest reliability analysis.

Richard's back: death, scoliosis and myth making.

Lund, Mary Ann

The body of a mediaeval monarch was always under scrutiny, and Richard III's was no exception. In death, however, his body became subject to new forms of examination and interpretation: stripped naked after the battle of Bosworth, his corpse was carried to Leicester and exhibited before being buried. In 2012, it was rediscovered. The revelation that Richard suffered from scoliosis prompts this article to re-evaluate the historical sources about Richard's physique and his posthumous reputation. This article argues that Richard's death and his myth as 'crookback' are inextricably linked and traces attitudes to spinal curvature in the early modern period. It also considers how Shakespeare represented Richard as deformed, and aspects of performance history which suggest physical vulnerability. It then considers Richard's scoliosis from the perspective of medical history, reviewing classical accounts of scoliosis and arguing that Richard was probably treated with a mixture of axial traction and pressure. It demonstrates from the evidence of Richard's medical household that he was well placed to receive hands-on therapies and considers in particular the role of his physician and surgeon, William Hobbes. Finally, it shows how the case of Richard III demonstrates the close relationship between politics and medicine in the period and the contorted process of historical myth making.

2015-01-01

Retinal degenerative diseases are major causes of vision loss and blindness worldwide and are characterized by chronic and progressive neuronal loss. One common feature of retinal degenerative diseases and brain neurodegenerative diseases is chronic neuroinflammation. There is growing evidence that retinal microglia, as in the brain, become activated in the course of retinal degenerative diseases, having a pivotal role in the initiation and propagation of the neurodegenerative process. A better understanding of the events elicited and mediated by retinal microglia will contribute to the clarification of disease etiology and might open new avenues for potential therapeutic interventions. This review aims at giving an overview of the roles of microglia-mediated neuroinflammation in major retinal degenerative diseases like glaucoma, age-related macular degeneration, and diabetic retinopathy.

Orthopaedic treatment for idiopathic scoliosis in adolescence is indicated with a curve of > or =20 degrees and a Risser score< or =4, because progression of curve is low with Risser scores >4. We present the case of a young man with a left lumbar idiopathic scoliosis (T12-L4) with a curve of 10 degrees, which was stable from 13 years (Risser 0) to 16 years old (Risser 4). The scoliosis progressed quickly after a Risser score of 4 was achieved. The man had been wearing a lift on the left foot since he was 13, because of a leg length discrepancy, and had been under clinical and radiological monitoring. When the boy reached 17 years, the scoliosis rapidly progressed, to a curve of 22 degrees and a Risser score of >4. The scoliosis was effectively treated with a Boston brace. At 20 years, the Risser score was 5, and the left lumbar curve was 13 degrees after discontinuing the use of the brace. To our knowledge, no scientific reference indicates a time limit to orthopaedic treatment for idiopathic adolescent scoliosis. Despite the experts' recommendations, a brace might be indicated with a Risser score > or =4 to stop the progression of the curve.

Background and purpose Cartilage damage can develop due to trauma, resulting in focal chondral or osteochondral defects, or as more diffuse loss of cartilage in a generalized organ disease such as osteoarthritis. A loss of cartilage function and quality is also seen with increasing age. There is a spectrum of diseases ranging from focal cartilage defects with healthy surrounding cartilage to focal lesions in degenerative cartilage, to multiple and diffuse lesions in osteoarthritic cartilage. At the recent Aarhus Regenerative Orthopaedics Symposium (AROS) 2015, regenerative challenges in an ageing population were discussed by clinicians and basic scientists. A group of clinicians was given the task of discussing the role of tissue engineering in the treatment of degenerative cartilage lesions in ageing patients. We present the outcomes of our discussions on current treatment options for such lesions, with particular emphasis on different biological repair techniques and their supporting level of evidence. Results and interpretation Based on the studies on treatment of degenerative lesions and early OA, there is low-level evidence to suggest that cartilage repair is a possible treatment for such lesions, but there are conflicting results regarding the effect of advanced age on the outcome. We concluded that further improvements are needed for direct repair of focal, purely traumatic defects before we can routinely use such repair techniques for the more challenging degenerative lesions. Furthermore, we need to identify trigger mechanisms that start generalized loss of cartilage matrix, and induce subchondral bone changes and concomitant synovial pathology, to maximize our treatment methods for biological repair in degenerative ageing joints.

Concurrent validity between postural indices obtained from digital photographs (two-dimensional [2D]), surface topography imaging (three-dimensional [3D]), and radiographs. To assess the validity of a quantitative clinical postural assessment tool of the trunk based on photographs (2D) as compared to a surface topography system (3D) as well as indices calculated from radiographs. To monitor progression of scoliosis or change in posture over time in young persons with idiopathic scoliosis (IS), noninvasive and nonionizing methods are recommended. In a clinical setting, posture can be quite easily assessed by calculating key postural indices from photographs. Quantitative postural indices of 70 subjects aged 10 to 20 years old with IS (Cobb angle, 15 degrees -60 degrees) were measured from photographs and from 3D trunk surface images taken in the standing position. Shoulder, scapula, trunk list, pelvis, scoliosis, and waist angles indices were calculated with specially designed software. Frontal and sagittal Cobb angles and trunk list were also calculated on radiographs. The Pearson correlation coefficients (r) was used to estimate concurrent validity of the 2D clinical postural tool of the trunk with indices extracted from the 3D system and with those obtained from radiographs. The correlation between 2D and 3D indices was good to excellent for shoulder, pelvis, trunk list, and thoracic scoliosis (0.81>r<0.97; P<0.01) but fair to moderate for thoracic kyphosis, lumbar lordosis, and thoracolumbar or lumbar scoliosis (0.30>r<0.56; P<0.05). The correlation between 2D and radiograph spinal indices was fair to good (-0.33 to -0.80 with Cobb angles and 0.76 for trunk list; P<0.05). This tool will facilitate clinical practice by monitoring trunk posture among persons with IS. Further, it may contribute to a reduction in the use of radiographs to monitor scoliosis progression.

Introversion, the prevalent trait of adolescents with idiopathic scoliosis: an observational study.

A large number of studies about adolescents with idiopathic scoliosis focus on health-related quality of life (HRQOL). However, only a few articles aim at evaluating the personality of these patients. Therefore, the purpose of the present research is to assess the personality traits of adolescents with idiopathic scoliosis and their relationship with HRQOL.Our hypothesis is that adolescents with idiopathic scoliosis present the principal personality trait of introversion, defined as self-reliance and inhibition in social relationships. This was a cross-sectional study. The examined group consisted of 43 patients (only 4 boys), mean age = 14.3 (SD = 2.23). On the day of the visit, HRQOL tools (Scoliosis Research Society-22 Questionnaire (SRS-22) and Trunk Appearance Perception Scale (TAPS)) and a personality test (16 Personality Factors-Adolescent Personality Questionnaire (16PF-APQ)) were completed; in addition, a posterior-anterior radiography was performed. Correlations among demographic and medical data and HRQOL and personality tests were assessed. Results for SRS-22 were as follows: Function 4.5 (SD = .4), Pain 4.3 (SD = .5), Self-image 3.6 (SD = .7), Mental Health 3.8. (SD = .7), and Subtotal 4.2 (SD = .7). Mean TAPS was 3.5 (SD = .6).In personality, the lowest values were assessed for Extroversion ( M  = 29.4, SD = 24.7) and Self-reliance ( M  = 71, SD = 25.3).Independence was negatively related to Self-image ( r  = -.51), Mental Health ( r  = -.54), and Subtotal SRS-22 ( r  = -.60) ( p  < .01). Adolescents with idiopathic scoliosis presented a common style of personality, characterized by social inhibition (introversion), preference for staying alone, and being self-sufficient (self-reliance).Specific programs in promoting social abilities may help adolescent patients with idiopathic scoliosis in finding a way to express themselves and to become more sociable. Correlational studies between personality and HRQOL need to be

Patients with idiopathic scoliosis, although otherwise healthy, often have significant concerns about their self-image and appearance. In a group of juveniles and adolescents, this can impact adjustment in school, functioning in peer groups, and general sense of well-being. There are limited data to help physicians reliably and precisely identify those who are at higher risk of poor emotional adjustment even after spine deformity correction. The purpose of this study was to determine the predictors of emotional maladjustment in juvenile and adolescent patients after surgical correction of idiopathic scoliosis. A total of 233 juveniles, mean age 11.26 ± 1.02 (range, 8 to 12) years and 909 adolescents, mean age 14.91 ± 1.61 (range, 13 to 21) years, who underwent surgical correction for idiopathic scoliosis and who were participating in a prospective longitudinal multicenter database, were enrolled in the study. Participants completed the Scoliosis Research Society-22 (SRS-22) questionnaire before surgery and 2 years postoperatively. Radiographs were used to measure Cobb angle and surface measurements were used to determine decompensation and trunk shift. Adolescents reported poorer mental health preoperatively (P<0.05) and 2 years postoperatively (P<0.001) than juveniles; however, both groups reported improved mental health (P<0.001) and self-image (P<0.01) postoperatively. Mental health 2 years postoperatively was predicted by preoperative self-image (P<0.05), mental health (P<0.001), and main thoracic Cobb angle (P<0.05) in the juvenile group. Within the adolescent group, mental health 2 years postoperatively was predicted by preoperative mental health (P<0.001); self-image 2 years postoperatively was predicted by preoperative mental health (P<0.01) and self-image (P<0.001). Self-image and mental health are significantly improved after spine deformity correction in juveniles and adolescents with idiopathic scoliosis. However, consistent with normative development

An upright body posture cannot be maintained passively for reasons including a high location of the centre of gravity (COG) and a small support area. Proper alignment of body parts is maintained automatically, tending towards a pattern encoded in the CNS. A particularly important role in posture regulation is played by the short muscles of the back, which respond to being stretched with a contraction. During the early phase of scoliosis, the CNS automatically corrects abnormalities, but over time habituation occurs and the CNS treats them as something normal. Any attempt to restore proper body alignment is treated as an error and CNS automatically restores this abnormal pattern. With a prolonged deviation in body part alignment, CNS treats it as a defect and runs compensatory mechanisms to restore the balance of the body as a whole. Balance is ensured by postural compensation, but this does not restore proper body part alignment. In the treatment of scoliosis, it is important both to slow down progression and to prevent the development of abnormal postural habits, which are part of a vicious circle even without progression. Secondary prevention is therefore needed in all patients. Passive observation limits the possibilities for prevention and contradicts the principle of early implementation of rehabilitation. Depending on the size of the angle of curvature, recommended treatments of scoliosis comprise observation, corset bracing, and surgery. Physiotherapy is often treated as an unconventional and ineffective treatment. Often, the biggest problem is transferring the resulting correction to automatic maintenance of a correct posture in the vertical position. The aim of this paper was to discuss the conservative treatment of scoliosis with regard to difficulties maintaining the correct alignment of the body parts in the vertical position that accompany scoliosis.

Scoliosis deformity has been linked with deleterious changes in the thoracic cavity that affect pulmonary function. The causal relationship between spinal deformity and pulmonary function has yet to be fully defined. It has been hypothesized that deformity correction improves pulmonary function by restoring both respiratory muscle efficiency and increasing the space available to the lungs. This research aims to correlate pulmonary function and thoracic volume before and after scoliosis correction. Retrospective correlational analysis between thoracic volume modeling from plain x-rays and pulmonary function tests was conducted. Adolescent idiopathic scoliosis patients enrolled in a multicenter database were sorted by pre-operative Total Lung Capacities (TLC) % predicted values from their Pulmonary Function Tests (PFT). Ten patients with the best and ten patients with the worst TLC values were included. Modeled thoracic volume and TLC values were compared before and 2 years after surgery. Scoliosis correction resulted in an increase in the thoracic volume for patients with the worst initial TLCs (11.7%) and those with the best initial TLCs (12.5%). The adolescents with the most severe pulmonary restriction prior to surgery strongly correlated with post-operative change in total lung capacity and thoracic volume (r 2  = 0.839; p < 0.001). The mean increase in thoracic volume in this group was 373.1 cm 3 (11.7%) which correlated with a 21.2% improvement in TLC. Scoliosis correction in adolescents was found to increase thoracic volume and is strongly correlated with improved TLC in cases with severe restrictive pulmonary function, but no correlation was found in cases with normal pulmonary function. © 2016 Orthopaedic Research Society.

The degeneration of photoreceptors in the retina is one of the major causes of adult blindness in humans. Unfortunately, no effective clinical treatments exist for the majority of retinal degenerative disorders. Here we report on the fabrication and functional validation of a fully organic prosthesis for long-term in vivo subretinal implantation in the eye of Royal College of Surgeons rats, a widely recognized model of retinitis pigmentosa. Electrophysiological and behavioural analyses reveal a prosthesis-dependent recovery of light sensitivity and visual acuity that persists up to 6-10 months after surgery. The rescue of the visual function is accompanied by an increase in the basal metabolic activity of the primary visual cortex, as demonstrated by positron emission tomography imaging. Our results highlight the possibility of developing a new generation of fully organic, highly biocompatible and functionally autonomous photovoltaic prostheses for subretinal implants to treat degenerative blindness.

Introduction Patients with severe idiopathic scoliosis are reported to have significant pulmonary complications, including recurrent chest infections, alveolar hypoventilation and respiratory failure. Case presentation We report a case of a 13-year-old boy with moderate-to-severe scoliosis resulting in torsion or twisting of the bronchus intermedius, which contributed to airflow obstruction defects, as revealed by both spirometry and bronchoscopy. Conclusion We recommend that inspection of the shape of the maximal expiratory flow-volume loop obtained from spirometry, as well as other parameters suggestive of obstructive lung disease, may be important in children with scoliosis. To the best of the authors' knowledge, this is the first report of a child in which pulmonary function testing and direct visualization via a flexible bronchoscope have been used to characterize intrathoracic large airway obstruction.

The purpose of this observational study was to investigate and analyze the social media presence of both patients and surgeons in relation to pediatric scoliosis. First, patient Instagram (Instagram, Inc., San Francisco, California) posts were evaluated for 1) media format; 2) timing in relation to surgery; 3) tone; 4) perspective; 5) content; and 6) subject reference. To analyze reciprocal engagement, the presence and activity of pediatric scoliosis surgeons at five major academic centers were subsequently analyzed on Instagram, Twitter (Twitter Inc., San Francisco, California), and LinkedIn (LinkedIn Corporation, Sunnyvale, California). A search of public Instagram profiles was performed over a one-year period from February 2016 to February 2017. Posts related to pediatric scoliosis were selected for analysis using a hashtag search with 30 related terms. A total of 982 posts were retrieved, with 669 posts meeting the inclusion criteria. Each post was then evaluated for timing, tone, perspective, and content using a categorical scoring system. An additional analysis was performed using academic orthopaedic hospitals' websites, in which the names of scoliosis surgeons were found and searched for on Instagram, Twitter, and LinkedIn. Their profiles were analyzed for level and length of activity, number of followers or connections, and references to clinical practice. A total of 669 posts related to scoliosis were analyzed, the majority of which were temporally related to non-operative (74.7%) or post-operative (21.8%) settings. Patients (33.3%), friends and family (34.4%), and professional organizations (23.8%) were the most active contributors. The vast majority of posts were positive in nature (88.9 %) and highlighted the patient experience (79.2%), specifically related to bracing (33.1%), activities of daily living (31.7%), and surgical site or x-rays (25.5%). Of the social media sites analyzed, surgeons were found to have the highest presence on LinkedIn (55

To identify the prevalence of lumbar scoliosis in breast cancer patients and to investigate the potential risk factors of lumbar scoliosis. A retrospective chart review was performed in breast cancer patients aged more than 40 years who underwent dual energy X-ray absorptiometry (DEXA) scanning between January 2014 and December 2014. We divided the patients into control and experimental groups in order to investigate the influence of breast cancer treatment. The curvature of the lumbar spine was measured by using the Cobb method on a DEXA scan. Scoliosis was defined by the presence of a curvature 10° or larger. The variables, including age, bone mineral density (BMD), body mass index (BMI), and breast cancer treatments, were also obtained from the medical chart. Prevalence of lumbar scoliosis was evaluated, and it was compared between the two groups. The relationships between lumbar scoliosis and these variables were also investigated. Lumbar scoliosis was present in 16 out of our 652 breast cancer patients. There was no difference in the prevalence of lumbar scoliosis between the control group (7/316) and the experimental group (9/336) (p=0.70). According to the logistic regression analysis, lumbar scoliosis had no significant association with operation, chemotherapy, hormone therapy, BMI, and BMD (p>0.05). However, age showed a significant relationship with prevalence of lumbar scoliosis (p<0.001; odds ratio, 1.11; 95% confidence interval, 1.054-1.170). Prevalence of lumbar scoliosis in patients with breast cancer was 2.45%. Lumbar scoliosis had no association with breast cancer treatments, BMD, and BMI. Age was the only factor related to the prevalence of lumbar scoliosis.

In children with Prader Willi syndrome (PWS), besides growth hormone (GH) therapy, control of the food environment and regular exercise, surgical treatment of scoliosis deformities seems the treatment of choice, even though the risks of spinal surgery in this specific population is very high. Therefore the question arises as to whether the risks of spinal surgery outweigh the benefits in a condition, which bears significant risks per se. The purpose of this systematic review of the Pub Med literature was to find mid or long-term results of spinal fusion surgery in patients with PWS, and to present the conservative treatment in a case study of nine patients with this condition. Types of studies included; all kinds of studies; retrospective and prospective ones, which reported upon the outcome of scoliosis surgery in patients with PWS.Types of participants included: patients with scoliosis and PWS.Type of intervention: surgery.Search strategy for identification of the studies; Pub Med; limited to English language and bibliographies of all reviewed articles.Nine patients with PWS from our data-base treated conservatively have been found, being 19 years or over at the time this study has been performed. The results of conservative management are described and related to the natural history and treatment results found in the Pub Med review. From 2210 titles displayed in the Pub Med database with the key word being "Prader Willi syndrome", 5 different papers were displayed at the date of the search containing some information on the outcome of surgery and none appeared to contain a mid or long-term follow-up. The PWS patients treated conservatively from our series all stayed below 70 degrees and some of which improved. If the curve of scoliosis patients with PWS can be kept within certain limits (usually below 70 degrees) conservatively, this treatment seems to have fewer complications than surgical treatments. The results of our retrospective study of nine patients

Since 1981, we have performed school scoliosis screening (SSS) using Moiré topography in Miyazaki, Japan and attained a certain result in detecting scoliosis. However, this screening system was discontinued due to cessation of repair and production of Moiré topographic equipment. The purpose of this study was to make clear both the results and the problems of SSS by Moiré topography on the basis of our past 33 years' experiences. The subjects were 689,293 students (5th grade boys in 200,329, 5th grade girls in 191,919, 8th grade boys in 151,351, and 8th grade girls in 145,694) who were screened by Moiré topography between 1981 and 2013. The number of students received SSS, the positive rate of Moiré topography, the discovery rate of scoliosis greater than 20°, the reference rate to the second screening, and the positive predictive value of Moiré topography to detect scoliosis greater than 20° were investigated. The number of students received SSS achieved a peak in 1992. The positive rate of Moiré topography and the discovery rate of scoliosis were highest in 8th grade girls. The reference rates to the second screening were 49.8% in 5th grade students and 41.4% in 8th grade students. The positive predictive values were 2.1% in 5th grade students and 7.6% in 8th grade students. SSS by Moiré topography seemed to be effective in detecting scoliosis although both the positive predictive value and the reference rate to the second screening were low. Copyright © 2018.

The aim of the study was to determine the level of basic knowledge about idiopathic scoliosis (IS) among students of physiotherapy. The study included 37 students of Medical University of Silesia (17F and 20M aged 22-25, mean 22.6), attending the 3(rd) year of a 1(st) degree of physiotherapy. All students had credits in kinesiotherapy, including methods of conservative treatment of IS. Students were examined using a questionnaire, comprising general knowledge of IS, questions related to sagittal plane correction, influence of various physical activities on IS and known methods of conservative treatment. 81 students considered IS as 3-D deformity. 62.2% of those questioned would diagnose IS when the Cobb angle reaches 10 degrees . All students agreed that the aetiology of IS remains unknown. 54.1% considered forcible extensory exercises of back as favourable in IS. Questioned students mostly preferred swimming (94.6%), yoga (73.0%) and martial arts (32.4%) as beneficial to IS. The methods of conservative treatment which were known best were: Lehnert-Schroth-Weiss (94.6%), Klapp (91.9%), Majoch (89.2%) and Dobosiewicz (78.4%). The conclusions indicate that the average level of knowledge of idiopathic scoliosis among students of physiotherapy is unsatisfactory, despite the education programme including the SOSORT guidelines. Education in the field of scoliosis should be comprehensive and meet contemporary guidelines and standards.

Knowledge on mechanisms of neurophysiological control of trunk movement and posture could help in the development of rehabilitation programs and brace treatment in adolescent idiopathic scoliosis (AIS). Reviewing up-to-date research on neurophysiology of movement and posture control with the aim of providing basis for new researches in the field of AIS rehabilitation and background understanding for clinicians engaged in management of AIS. Review of literature. We considered several neurophysiological issues relevant for AIS rehabilitation, namely, the peculiar organization of patterns of trunk muscle recruitment, the structure of the neural hardware subserving axial and arm muscle control, and the relevance of cognitive systems allowing mapping of spatial coordinates and building of body schema. We made clear the reason why trunk control is generally carried out by means of very fast, feedforward or feedback driven patterns of muscle activation which are deeply rooted in our neural control system and very difficult to modify by training. We hypothesized that augmented sensory feedback and strength exercises could be an important stage in a rehabilitation program aimed at hindering, or possibly reversing, scoliosis progression. In this context we considered bracing not only as a corrective biomechanical device but also as a tool for continuous sensory stimulation that could help awareness of body misalignment. Future research aimed at developing strategies of trunk postural control learning is essential in the rehabilitation of adolescent idiopathic scoliosis.

To investigate the short-term outcomes of treatment utilizing an outpatient scoliosis- specific back school program in thirty-six patients with adolescent idiopathic scoliosis (AIS). Improved signs and symptoms of AIS have been reported in response to curve-patternspecific exercise therapy programs. Additional outcome studies are needed. Thirty-six patients with adolescent idiopathic scoliosis (AIS), 33 females and 3 males, completed a twenty-hour multimodal exercise program (Schroth Best Practice® - SBP) for five to seven days at Scoliosis 3DC(SM). Average age was 13.89 years and average Cobb angles were 36.92° thoracic and 33.92° lumbar. The sample was comprised of patients under treatment from August 2011 to February 2015 who never had scoliosis-related surgery and who were not undergoing brace treatment. SBP program components included physio-logic® exercises, mobilizations, activities of daily living (ADLs), 3-D Made Easy®, and Schroth exercises. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), chest expansion (CE), and angle of trunk rotation (ATR) were clinical parameters used to evaluate results of this outpatient scoliosis-specific exercise program. Highly significant improvements were noted in FVC, FEV1, CE and Scoliometer(TM) readings. A short-term outpatient SBP program was found to have a positive influence on FVC, FEV1, ATR, and CE. We will present long-term results in a subsequent study.

Idiopathic scoliosis is a three-dimensional structural deformity of the spine that occurs in children and adolescents. Recent reviews on bracing and exercise treatment have provided some evidence for effect of these interventions. The purpose of this study is to improve the evidence base regarding the effectiveness of conservative treatments for preventing curve progression in idiopathic scoliosis. Previously untreated girls and boys with idiopathic scoliosis, 9 to 17 years of age with at least one year of remaining growth and a curve Cobb angle of 25-40 degrees will be included. A total of 135 participants will be randomly allocated in groups of 45 patients each to receive one of the three interventions. All three groups will receive a physical activity prescription according to the World Health Organisation recommendations. One group will additionally wear a hyper-corrective night-time brace. One group will additionally perform postural scoliosis-specific exercises. Participation in the study will last until the curve has progressed, or until cessation of skeletal growth. OUTCOME variables will be measured every 6 months. The primary outcome variable, failure of treatment, is defined as progression of the Cobb angle more than 6 degrees, compared to the primary x-ray, seen on two consecutive spinal standing x-rays taken with 6 months interval. Secondary outcome measures include the SRS-22r and EQ5D-Y quality of life questionnaires, the International Physical Activity Questionnaire (IPAQ) short form, and Cobb angle at end of the study. This trial will evaluate which of the tested conservative treatment approaches that is the most effective for patients with adolescent idiopathic scoliosis. NCT01761305.

The surgical treatment of severe adolescent spinal deformities is challenging and carries substantial risks of mortality and morbidity. To mitigate this risk, surgeons have employed various methods as this study designed to evaluate the safety and effectiveness of preoperative halo-femoral or halo gravity traction (HGT) followed by posterior-only surgery in the management of severe scoliosis. A total number of 23 patients with severe scoliosis treated by preoperative skeletal traction (halo gravity or halo femoral) followed by posterior fusion and instrumentation in one stage. All patients were followed for a minimum of 2 years after surgery. The average age of the patients was 12.7 years at the time of surgery. Mean of the Cobb angle improved from 99.9° ± 8.2° preoperatively to 75.3° ± 8° post-traction and 49.5° ± 7.7° postoperatively. Kyphosis angle corrected from 56.4° ± 9.5° to 38.6° ± 5.8°. The preop-FVC% was 41 ± 6.1% and after 1 year follow-up FVC% was 45.7 ± 7.7%. No patients required an anterior release due to amount of their deformity. Despite the benefits of modern instrumentation procedures, the treatment of severe scoliosis can be very competing. We think that by applying preoperative halo femoral traction and halo-gravity traction, managing severe scoliosis will be in safe and easy manner and can lead to better deformity correction and less neurological complications and facilitate to avoid anterior operation for severe scoliosis and its related complications.

The purpose of this case report is to describe physical therapy (PT) for a child with infantile idiopathic scoliosis and motor delay. A 10-month-old boy with a 28° left thoracolumbar scoliosis was referred for PT and was seen weekly in his home over a 6-month period following a diagnosis of scoliosis and delayed gross motor milestones. Before the initiation of PT, the child was scheduled to undergo serial casting for correction of the spinal curve and was not yet rolling or transitioning in or out of sitting. By the end of the 6-month intervention period, the spinal curve had resolved to 12° without the need for serial casting and the child was walking independently. PT appeared to have a positive effect on reduction of the spinal curve and achievement of gross motor milestones.

The syrinx can occur in any region of the spinal cord and is common in cervical and/or thoracic region, and distributing along spinal cord is unusual, especially association with Chiari II malformation and scoliosis. To report a first case of entire syringomyelia associated with Chiari II malformation and severe scoliosis and hydrocephalus. The patient began to experience symptoms of bilateral hand weakness in adulthood. In this patient, MR imaging of the brain and spine showed syrinx along entire spine and hydrocephalus, cerebellar tonsillar herniation, and expansion of the fourth ventricle and posterior cranial fossa. The patient underwent operative treatment to prevent the progression of her neurological deficit. At 12 months' follow-up, the patient's neurological deficit remains stable with the scoliosis left untreated. Foramen magnum decompression, duraplasty and syrinx-shunting are effective methods even to CM II and entire syrinx.

Sagittal balance and idiopathic scoliosis: does final sagittal alignment influence outcomes, degeneration rate or failure rate?

PubMed

2018-02-01

In the last decade, spine surgeons have been impacted by the "sagittal plane analysis revolution". Significant correlations have been found in adult spinal deformity (ASD) between sagittal lumbo-pelvic parameters and functional outcomes, but most of them do not apply in adolescent idiopathic scoliosis (AIS). Meanwhile, instrumentation and reduction strategies have considerably evolved. This paper aims to describe the preoperative sagittal alignment in AIS, and to report literature evidence regarding the influence of postoperative sagittal balance on complication rates, low back pain incidence and disc degeneration. A bibliographic search in Medline and Google database from 1984 to May 2017 was performed. The keywords included 'adolescent idiopathic scoliosis', 'adult scoliosis', 'sagittal alignment', 'proximal junctional kyphosis', 'distal junctional kyphosis', 'outcomes', 'low back pain' and 'complication', used individually or in combination. Algorithms of sagittal balance analysis and treatment decision have been reported in ASD, but the clinical situation is very different in children. Sagittal alignment greatly varies in AIS among the various Lenke types. Most patients are clinically balanced before surgery, but the spinal harmony is altered, with overgrowth of the anterior column and global sagittal flattening (undersestimated in 2D). The exact role of pelvic incidence and whether or not patients also use pelvic compensation to maintain balance still require further clarification. The incidence of radiological junctional failures remains highly variable, depending on definitions, cohort size and follow-up. Preoperative hyperkyphosis seems to be a consistent and relevant risk factor. Current literature does not support the recent trend to save motion segments (selective fusion), and no significant association was found between the distal level of fusion and the incidence of low back pain. Postoperative sagittal alignment seems to be more important than LIV

Treatment for severe scoliosis is usually attained when the scoliotic spine is deformed and fixed by implant rods. Investigation of the intraoperative changes of implant rod shape in three-dimensions is necessary to understand the biomechanics of scoliosis correction, establish consensus of the treatment, and achieve the optimal outcome. The objective of this study was to measure the intraoperative three-dimensional geometry and deformation of implant rod during scoliosis corrective surgery.A pair of images was obtained intraoperatively by the dual camera system before rotation and after rotation of rods during scoliosis surgery. The three-dimensional implant rod geometry before implantation was measured directly by the surgeon and after surgery using a CT scanner. The images of rods were reconstructed in three-dimensions using quintic polynomial functions. The implant rod deformation was evaluated using the angle between the two three-dimensional tangent vectors measured at the ends of the implant rod.The implant rods at the concave side were significantly deformed during surgery. The highest rod deformation was found after the rotation of rods. The implant curvature regained after the surgical treatment.Careful intraoperative rod maneuver is important to achieve a safe clinical outcome because the intraoperative forces could be higher than the postoperative forces. Continuous scoliosis correction was observed as indicated by the regain of the implant rod curvature after surgery.

Introduction: It has long been said that exercise-based rehabilitation for scoliosis is ineffective, however, these reports studied general exercises. This case report is a prospective one-year follow-up of a nearly skeletally mature adolescent female (Risser 4) with idiopathic scoliosis treated with Pattern-Specific-Scoliosis Rehabilitation (PSSR). Methods: The 15-year old patient recommended for surgery (initial Cobb angle of 45°) completed a 16-hour scoliosis-specific back school (according to Schroth Best Practice®), over the course of five weeks. She continued with her program at home, and followed up with the lead author after 6 months and 1 year. Results: The patient achieved a 13° reduction in her primary thoracic Cobb angle. Postural improvement and reduction in trunk rotation (ATR) was also achieved (-4° in the thoracic spine, and -5° in the lumbar spine). Conclusion: Pattern-specific scoliosis rehabilitation (PSSR) works to reduce the asymmetrical load caused by scoliosis. PSSR is effective in stabilizing Cobb angle, and can, in some cases, reduce Cobb angle in adolescents. Patients recommended for surgery may be candidates for conservative treatment. This case suggests that the practice of discontinuing conservative treatment at Risser stage 4 should be re-evaluated. PMID:29399225

The aim of spinal deformity correction is to restore the spine's functional alignment by balancing it in both the sagittal and coronal planes. Regardless of posture, the ideal coronal profile is straight, and therefore readily assessable. This study compares two radiological methods to determine which better predicts postoperative standing coronal balance. We conducted a single-center, radiographic comparative study between 2011 and 2015. A total of 199 patients with a mean age of 55.1 years were studied. Ninety patients with degenerative lumbar scoliosis (DLS) and 109 ankylosing spondylitis (AS) were treated with posterior surgery during this period. Baseline clinical and radiographic parameters (sagittal and coronal) were recorded. Comparison was performed between the new supra-acetabular line (central sacral vertical line [CSVL1]) and conventional supra-iliac line (CSVL2) perpendicular methods of coronal balance assessment. These methods were also compared with the gold standard standing C7 plumb line. Each patient underwent standardized operative procedures and had perioperative spine X-rays obtained for assessment of spinal balance. Adjusted multivariate analysis was used to determine predictors of coronal balance. Significant differences in baseline characteristics (age, gender, and radiographic parameters) were found between patients with DLS and AS. CSVL1, CSVL2, and C7 plumb line differed in all the perioperative measurements. These three radiological methods showed a mean right coronal imbalance for both diagnoses in all pre-, intra-, and postoperative radiographs. The magnitude of imbalance was the greatest for CSVL2 followed by CSVL1 and subsequently the C7 plumb line. A larger discrepancy between CSVL and C7 plumb line measurements intraoperatively than those postoperatively suggests a postural effect on these parameters, which is greater for CSVL2. Multivariate analysis identified that in DLS, the preoperative C7 plumb line was predictive of its

Loss of thoracic kyphosis has been associated with thoracic idiopathic scoliosis. Modern 3-dimensional (3D) imaging systems allow more accurate characterization of the scoliotic deformity than traditional radiographs. In this study, we utilized 3D calculations to characterize the association between increasing scoliosis severity and changes in the sagittal and axial planes. Patients evaluated in a scoliosis clinic and determined to have either a normal spine or idiopathic scoliosis were included in the analysis. All underwent upright, biplanar radiography with 3D reconstructions. Two-dimensional (2D) measurements of the magnitude of the thoracic major curve and the thoracic kyphosis were recorded. Image processing and MATLAB analysis were utilized to produce a 3D calculation of thoracic kyphosis and apical vertebral axial rotation. Regression analysis was performed to determine the correlation of 2D kyphosis, 3D kyphosis, and apical axial rotation with the magnitude of the thoracic major curve. The 442 patients for whom 2D and 3D data were collected had a main thoracic curve magnitude ranging from 1° to 118°. Linear regression analysis of the 2D and 3D T5-T12 kyphosis versus main thoracic curve magnitude yielded significant models (p < 0.05). The 2D model had a minimally negative slope (-0.07), a small R value (0.02), and a poor correlation coefficient (-0.14). In contrast, the 3D model had a strongly negative slope (-0.54), a high R value (0.56), and a strong correlation coefficient (-0.75). Curve magnitude also had a strong correlation with loss of 3D T1-T12 kyphosis and increasing apical axial rotation. Segmentally calculated 3D thoracic kyphosis had a strongly negative correlation with the magnitude of the main thoracic curve. With near uniformity, 3D thoracic kyphosis progressively decreased as scoliosis magnitude increased, at a rate of more than half the increase in the main thoracic curve magnitude. Analysis confirmed a surprisingly strong correlation

A computer program was created to identify and accept spatial data regarding the location of the thoracic and lumbar vertebral bodies on scoliosis films. With this information, the spine can be mathematically reconstructed and a scoliotic angle calculated. There was a 0.968 positive correlation between the computer and manual methods of measuring scoliosis. The computer method was more reproducible with a standard deviation of only 1.3 degrees. Computerized measurement of scoliosis also provides better evaluation of the true shape of the curve.

Adolescent idiopathic scoliosis: Indications and efficacy of nonoperative treatment

PubMed Central

Canavese, Federico; Kaelin, André

2011-01-01

The strategy for the treatment of idiopathic scoliosis depends essentially upon the magnitude and pattern of the deformity, and its potential for progression. Treatment options include observation, bracing and/or surgery. During the past decade, several studies have demonstrated that the natural history of adolescent idiopathic scoliosis can be positively affected by nonoperative treatment, especially bracing. Other forms of conservative treatment, such as chiropractic or osteopathic manipulation, acupuncture, exercise or other manual treatments, or diet and nutrition, have not yet been proven to be effective in controlling spinal deformity progression, and those with a natural history that is favorable at the completion of growth. Observation is appropriate treatment for small curves, curves that are at low risk of progression, and those with a natural history that is favorable at the completion of growth. Indications for brace treatment are a growing child presenting with a curve of 25°–40° or a curve less than 25° with documented progression. Curves of 20°–25° in patients with pronounced skeletal immaturity should also be treated. The purpose of this review is to provide information about conservative treatment of adolescent idiopathic scoliosis. Indications for conservative treatment, hours daily wear and complications of brace treatment as well as brace types are discussed. PMID:21221217

Introduction: Idiopathic scoliosis is a significant health problem which occurs in 2%–4% school kids in adolescent age. Reasons of occurrence are not quite clear, there are many theories, but probably it is multifactor disease. Among the theories that are mentioned some of them included environmental and behavioral factors. Aim: Research the impact of some environmental and behavioral factor on development and progression of idiopathic scoliosis in school kids. Methodology: Research was conducted on 421 pupil in adolescent age, where 120 pupils was from urban schools and 301 pupil from rural schools. Environmental factors and habits like the bigger osteomuscular structure mobility at kids from rural schools, longer outdoor time spending, different nutrition, alcoholism and smoking, different obligations, etc. factors which can be cause of scoliosis development. Results: In this research we assumed that different environmental and behavioral factors of school kids, which exist in rural and urban areas, can develop to different expression of scoliosis in these areas. In our research we proved that the scoliosis occurrence is more often in urban areas than in rural (Fisher’s exact test P<0.001). Conclusion: It is necessary to research all factors of lifestyle individually, which are different between the urban and rural kids. PMID:23678322

Improving excellence in scoliosis rehabilitation: a controlled study of matched pairs.

PubMed

Weiss, H-R; Klein, R

2006-01-01

Physiotherapy programmes so far mainly address the lateral deformity of scoliosis, a few aim at the correction of rotation and only very few address the sagittal profile. Meanwhile, there is evidence that correction forces applied in the sagittal plane are also able to correct the scoliotic deformity in the coronal and frontal planes. So it should be possible to improve excellence in scoliosis rehabilitation by the implementation of exercises to correct the sagittal deformity in scoliosis patients. An exercise programme (physio-logic exercises) aiming at a physiologic sagittal profile was developed to add to the programme applied at the centre or to replace certain exercises or exercising positions. To test the hypothesis that physio-logic exercises improve the outcome of Scoliosis Intensive Rehabilitation (SIR), the following study design was chosen: Prospective controlled trial of pairs of patients with idiopathic scoliosis matched by sex, age, Cobb angle and curve pattern. There were 18 patients in the treatment group (SIR + physio-logic exercises) and 18 patients in the control group (SIR only), all in matched pairs. Average Cobb angle in the treatment group was 34.5 degrees (SD 7.8) Cobb angle in the control group was 31.6 degrees (SD 5.8). Age in the treatment group was at average 15.3 years (SD 1.1) and in the control group 14.7 years (SD 1.3). Thirteen of the 18 patients in either group had a brace. Outcome parameter: average lateral deviation (mm), average surface rotation ( degrees ) and maximum Kyphosis angle ( degrees ) as evaluated with the help of surface topography (Formetric-system). Lateral deviation (mm) decreased significantly after the performance of the physio-logic programme and highly significantly in the physio-logic ADL posture; however, it was not significant after completion of the whole rehabilitation programme (2.3 vs 0.3 mm in the controls). Surface rotation improved at average 1.2 degrees in the treatment group and 0.8 degrees in the

In this study, we sought to evaluate radiographic, functional, and quality-of-life outcomes of patients who have completed growth-sparing management of early-onset scoliosis. This prospective study involved patients with early-onset scoliosis who underwent growth-sparing treatment and either "final" fusion or observation for ≥2 years since the last lengthening procedure. Demographics, radiographic parameters, pulmonary function test (PFT) values, and scores of patient-reported assessments (Early-Onset Scoliosis Questionnaire [EOSQ] and Scoliosis Research Society [SRS]-30) were obtained. At the most recent follow-up, patients performed 2 additional functional outcome tests: step-activity monitoring and a treadmill exercise-tolerance test. Twelve patients were evaluated as "graduates" of growth-sparing management of early-onset scoliosis (mean of 37 months since the most recent surgery). The major scoliosis curve measurement averaged 88° before treatment and 47° at the most recent follow-up. T1-S1 height increased from a mean of 22.3 cm to 34.7 cm and T1-T12 height, from 13.3 to 22.3 cm. At the most recent follow-up, the mean forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) as a percentage of the predicted volume were 52.1% and 55.3%, respectively, and were essentially unchanged from the earliest PFT that patients could perform (FEV1 = 53.8% of predicted and FVC = 53.5% of predicted). There was no difference between graduates and controls with respect to activity time or total steps in step-activity monitoring, and in the exercise-tolerance test, graduates walked at the same speed but at a higher heart rate and at a significantly higher (p <0.001) VO2 cost (rate of oxygen consumed per distance traveled). The EOSQ mean score was 102.2 of a possible 120 points, and the SRS mean score was 4.1 of a possible 5 points. A realistic long-term goal for the management of early-onset scoliosis appears to be spine elongation and maintenance of

A recent study suggests a correlation between idiopathic scoliosis in adolescence and eating disorders. However, this does not correspond with our clinical experience in the same population. The aim of this study was to verify the correlation between scoliosis and eating disorders in adolescence. A cross-sectional study was designed including 187 consecutive adolescent girls with a diagnosis of idiopathic scoliosis (mean Cobb angle 26°, range 11-73°, age 15.2±2.5; 24% juveniles, 76% adolescent type) and 93 schoolgirls as controls (age 14.9±1.0). All of the participants answered the Italian validated questionnaire EAT-26 about eating habits in order to identify any eating disorders. Body mass index (BMI) was calculated for all participants and compared to reference data. chi-square test, Student's t-test, Pearson's correlation coefficient. Only 3 (1.6%; 95% CI -0.2-3.4%) participants in the scoliosis group showed EAT-26 scores suggestive for eating disorders versus 7 (7.5%; 95% CI 2.2-12.9%) in the school population (p<0.05). The BMI was slightly lower (p<0.05) for scoliosis patients (19±0.2) than for school girls (21±0.3). EAT-26 is recognized among the most valid questionnaires for eating disorders and has been widely applied in various countries. By applying this questionnaire, a lower incidence of eating disorders in female scoliosis patients was found than in the general population (using both our own controls and Italian reference values). This contrasts with some expert opinions and a recent study performed in Italy. The low BMI already reported in the literature as being typical of scoliosis participants is confirmed by our data.

This study aims to evaluate trunk local stability in a group of patients with degenerative primary cerebellar ataxia and to correlate it with spatio-temporal parameters, clinical variables, and history of falls. Sixteen patients affected by degenerative cerebellar ataxia and 16 gender- and age-matched healthy adults were studied by means of an inertial sensor to measure trunk kinematics and spatio-temporal parameters during over-ground walking. Trunk local dynamic stability was quantified by the maximum Lyapunov exponent with short data series of the acceleration data. According to this index, low values indicate more stable trunk dynamics, while high values denote less stable trunk dynamics. Disease severity was assessed by means of International Cooperative Ataxia Rating Scale (ICARS) according to which higher values correspond to more severe disease, while lower values correspond to less severe disease.Patients displayed a higher short-term maximum Lyapunov exponent than controls in all three spatial planes, which was correlated with the age, onset of the disease, and history of falls. Furthermore, the maximum Lyapunov exponent was negatively correlated with ICARS balance, ICARS posture, and ICARS total scores.These findings indicate that trunk local stability during gait is lower in patients with cerebellar degenerative ataxia than that in healthy controls and that this may increase the risk of falls. Local dynamic stability of the trunk seems to be an important aspect in patients with ataxia and could be a useful tool in the evaluation of rehabilitative and pharmacological treatment outcomes.

Scoliosis in Chickens: Responsiveness of Severity and Incidence to Dietary Copper

NASA Astrophysics Data System (ADS)

Opsahl, William; Abbott, Ursula; Kenney, Cristina; Rucker, Robert

1984-07-01

The severity and incidence of spinal lesions were manipulated in a line of chickens susceptible to scoliosis by varying their dietary intake of copper. A decrease in expression of the lesion was related to increased intake of copper. The change in expression, however, appeared to be related only indirectly to the defects in collagen cross-linking, maturation, and deposition known to be associated with dietary copper deficiency. Thus, a dietary constituent in the range of normal intakes may act as an environmental factor in the expression of scoliosis.

The symptomatic degenerative meniscus continues to be a source of discomfort for a significant number of patients. With vascular penetration of less than one-third of the adult meniscus, healing potential in the setting of chronic degeneration remains low. Continued hoop and shear stresses upon the degenerative meniscus results in gross failure, often in the form of complex tears in the posterior horn and midbody. Patient history and physical examination are critical to determine the true source of pain, particularly with the significant incidence of simultaneous articular pathology. Joint line tenderness, a positive McMurray test, and mechanical catching or locking can be highly suggestive of a meniscal source of knee pain and dysfunction. Radiographs and magnetic resonance imaging are frequently utilized to examine for osteoarthritis and to verify the presence of meniscal tears, in addition to ruling out other sources of pain. Non-operative therapy focused on non-steroidal anti-inflammatory drugs and physical therapy may be able to provide pain relief as well as improve mechanical function of the knee joint. For patients refractory to conservative therapy, arthroscopic partial meniscectomy can provide short-term gains regarding pain relief, especially when combined with an effective, regular physiotherapy program. Patients with clear mechanical symptoms and meniscal pathology may benefit from arthroscopic partial meniscectomy, but surgery is not a guaranteed success, especially with concomitant articular pathology. Ultimately, the long-term outcomes of either treatment arm provide similar results for most patients. Further study is needed regarding the short and long-term outcomes regarding conservative and surgical therapy, with a particular focus on the economic impact of treatment as well. PMID:25405088

Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

Over the last decade, the emergence of social networking websites such as Facebook have revolutionized information dissemination and broadened opportunities to engage in discussions. In particular, having been widely adopted in the younger generation, the use of this medium has become more prevalent in health disorders such as scoliosis in the adolescent population. However, the quality of information on Facebook is unregulated and variable, which may mislead patients in their decision making. To document the various types of information available and assess the quality of information on Facebook discussion boards using recognized scoring systems. To evaluate the quality of information on the social network. A search for the keyword "scoliosis" on Facebook was performed and the first 100 pages generated were reviewed. SCSS and DISCERN score. Content analysis was performed on discussion boards and personal blogs. Two independent examiners evaluated each site according to scoliosis-specific content score (SCSS) and the DISCERN criteria, both previously used instruments to judge the quality of information on the Internet pertaining to scoliosis. The SCSS range from 0 to 32 (higher score better) and the DISCERN 16 to 80 (higher score better). Of the 100 sites reviewed, 33 were discussion boards and personal blogs. Of these, the overall average SCSS was 5.7 (SD 5.8, range 0-20) and the DISCERN was 22.5 (SD 7.6, range 16-45), indicating that using general scoring systems the quality of information provided was overall poor. Using recognized scoring systems to analyze Facebook pages used as discussion forums or blogs, we showed that the quality in general was poor. For modern practices to adapt to an era of information exchange via the social network, the orthopedic community should develop ways to incorporate the social media in future patient education.

CONTRAIS: CONservative TReatment for Adolescent Idiopathic Scoliosis: a randomised controlled trial protocol

PubMed Central

2013-01-01

Background Idiopathic scoliosis is a three-dimensional structural deformity of the spine that occurs in children and adolescents. Recent reviews on bracing and exercise treatment have provided some evidence for effect of these interventions. The purpose of this study is to improve the evidence base regarding the effectiveness of conservative treatments for preventing curve progression in idiopathic scoliosis. Methods/design Patients: Previously untreated girls and boys with idiopathic scoliosis, 9 to 17 years of age with at least one year of remaining growth and a curve Cobb angle of 25–40 degrees will be included. A total of 135 participants will be randomly allocated in groups of 45 patients each to receive one of the three interventions. Interventions: All three groups will receive a physical activity prescription according to the World Health Organisation recommendations. One group will additionally wear a hyper-corrective night-time brace. One group will additionally perform postural scoliosis-specific exercises. Outcome: Participation in the study will last until the curve has progressed, or until cessation of skeletal growth. Outcome variables will be measured every 6 months. The primary outcome variable, failure of treatment, is defined as progression of the Cobb angle more than 6 degrees, compared to the primary x-ray, seen on two consecutive spinal standing x-rays taken with 6 months interval. Secondary outcome measures include the SRS-22r and EQ5D-Y quality of life questionnaires, the International Physical Activity Questionnaire (IPAQ) short form, and Cobb angle at end of the study. Discussion This trial will evaluate which of the tested conservative treatment approaches that is the most effective for patients with adolescent idiopathic scoliosis.

Bracing is the most common nonsurgical treatment for adolescent idiopathic scoliosis. Spinal braces affect glenohumeral and scapulothoracic motion because they restrict trunk movements. However, the potential spinal-bracing effects on scapular kinematics are unknown. The present study aimed to investigate the acute effects of spinal bracing on scapular kinematics in adolescent idiopathic scoliosis. Scapular kinematics, including scapular internal/external rotation, posterior/anterior tilting, and downward/upward rotation during scapular plane elevation, were evaluated in 27 in-brace and out-of-brace adolescent idiopathic scoliosis patients with a three-dimensional electromagnetic tracking system. Data on the position and orientation of the scapula at 30°, 60°, 90°, and 120° humerothoracic elevation were used for statistical comparisons. The paired t-test was used to assess the differences between the mean values of in-brace and out-of-brace conditions. The in-brace condition showed significantly increased (P<0.05) scapular anterior tilting and decreased internal rotation in the resting position on the convex and concave sides; increased scapular downward rotation at 120° humerothoracic elevation on the convex side and at 30°, 60°, 90°, and 120° humerothoracic elevation on the concave side; increased scapular anterior tilt at 30°, 60°, 90°, and 120° humerothoracic elevation on the convex and concave sides; and decreased (P<0.05) maximal humerothoracic elevation of the arm. Spinal bracing affects scapular kinematics. Observed changes in scapular kinematics with brace may also affect upper extremity function for adolescents with idiopathic scoliosis. Therefore, clinicians should include assessments of the glenohumeral and scapulothoracic joints when designing rehabilitation protocols for patients with adolescent idiopathic scoliosis.

Scoliosis surgery usually is associated with large volume of intraoperative blood loss, and cell salvage is used commonly to filter and retranfusion autologous blood to patients. The efficacy of using cell salvage in scoliosis surgery, however, is still controversial. The purpose of this study is to make clear that intraoperative use of cell salvage is effective to decrease the volume of perioperative allogenic blood transfusion in scoliosis surgery. A meta-analysis was conducted to identify the relevant studies from PubMed, Embase, Medline, Cochrane library, and Google scholar until July 2016. All randomized trials and controlled clinical studies comparing the clinical outcomes of using cell salvage versus noncell salvage in scoliosis surgery were retrieved for the meta-analysis. The data were analyzed by RevMan 5.3. A total of 7 studies with 562 patients were included in this meta-analysis. Based on the analysis, the volumes of perioperative and postoperative allogenic red blood cell (RBC) transfusion in cell salvage group were significantly less than those in control group (P = 0.04 and P = 0.01); however, no significant difference was detected in the amount of intraoperative allogenic RBC transfusion and the risk of patients needing allogenic blood transfusion between the 2 groups (P = 0.14 and P = 0.61). Both the hemoglobin and hematocrit levels on the first day after surgery were significantly greater in cell salvage group than those in control group (P = 0.002 and P < 0.001). No significant differences, however, were noted in neither hemoglobin nor hematocrit level at the time of discharge between the 2 groups (P = 0.76 and P = 0.32). One of the included study reported the number of patients with complications related to transfusion in the two groups, which was not significant different (P = 0.507). Cell salvage significantly reduced the volumes of perioperative and postoperative allogenic RBC transfusion in scoliosis surgery and increased the

Adolescent idiopathic scoliosis (AIS) is a common orthopedic disorder of unknown etiology and pathogenesis. Melatonin and melatonin pathway dysfunction has been widely suspected to play an important role in the pathogenesis. Many different types of animal models have been developed to induce experimental scoliosis mimicking the pathoanatomical features of idiopathic scoliosis in human. The scoliosis deformity was believed to be induced by pinealectomy and mediated through the resulting melatonin-deficiency. However, the lack of upright mechanical spinal loading and inherent rotational instability of the curvature render the similarity of these models to the human counterparts questionable. Different concerns have been raised challenging the scientific validity and limitations of each model. The objectives of this review follow the logical need to re-examine and compare the relevance and appropriateness of each of the animal models that have been used for studying the etiopathogenesis of adolescent idiopathic scoliosis in human in the past 15 to 20 years.

Generalised Joint Hypermobility in Caucasian Girls with Idiopathic Scoliosis: Relation with Age, Curve Size, and Curve Pattern

PubMed Central

2014-01-01

The aim of the study was to assess the prevalence of generalised joint hypermobility (GJH) in 155 girls with idiopathic scoliosis (IS) (age 9–18 years, mean 13.8 ± 2.3). The control group included 201 healthy girls. The presence of GJH was assessed with Beighton (B) test. GJH was diagnosed in 23.2% of IS girls and in 13.4% of controls (P = 0.02). The prevalence of GJH was significantly (P = 0.01) lower in IS girls aged 16–18 years in comparison with younger individuals. There was no difference regarding GJH occurrence between girls with mild (11–24°), moderate (25–40°), and severe scoliosis (>40°) (P = 0.78), between girls with single thoracic, single lumbar, and double curve scoliosis (P = 0.59), and between girls with thoracic scoliosis length ≤7 and >7 vertebrae (P = 0.25). No correlation between the number of points in B and the Cobb angle (P = 0.93), as well as between the number of points in B and the number of the vertebrae within thoracic scoliosis (P = 0.63), was noticed. GJH appeared more often in IS girls than in healthy controls. Its prevalence decreased with age. No relation between GJH prevalence and curve size, curve pattern, or scoliosis length was found.

Weiss, Hans-Rudolf; Goodall, Deborah

2009-01-01

In children with Prader Willi syndrome (PWS), besides growth hormone (GH) therapy, control of the food environment and regular exercise, surgical treatment of scoliosis deformities seems the treatment of choice, even though the risks of spinal surgery in this specific population is very high. Therefore the question arises as to whether the risks of spinal surgery outweigh the benefits in a condition, which bears significant risks per se. The purpose of this systematic review of the Pub Med literature was to find mid or long-term results of spinal fusion surgery in patients with PWS, and to present the conservative treatment in a case study of nine patients with this condition. Types of studies included; all kinds of studies; retrospective and prospective ones, which reported upon the outcome of scoliosis surgery in patients with PWS. Types of participants included: patients with scoliosis and PWS. Type of intervention: surgery. Search strategy for identification of the studies; Pub Med; limited to English language and bibliographies of all reviewed articles. Nine patients with PWS from our data-base treated conservatively have been found, being 19 years or over at the time this study has been performed. The results of conservative management are described and related to the natural history and treatment results found in the Pub Med review. From 2210 titles displayed in the Pub Med database with the key word being "Prader Willi syndrome", 5 different papers were displayed at the date of the search containing some information on the outcome of surgery and none appeared to contain a mid or long-term follow-up. The PWS patients treated conservatively from our series all stayed below 70° and some of which improved. If the curve of scoliosis patients with PWS can be kept within certain limits (usually below 70 degrees) conservatively, this treatment seems to have fewer complications than surgical treatments. The results of our retrospective study of nine patients

Duchenne muscular dystrophy, a progressive muscle disorder that occurs in males, causes a gradual decline in muscle strength. This progressive decline is associated with the development of scoliosis. Previous studies have shown that the use of glucocorticoids slows the progression of scoliosis, but it is unknown if the spine remains straight in the long term. We examined if glucocorticoid treatment has a long-term effect on the prevalence of scoliosis. Fifty-four boys who had been diagnosed with Duchenne muscular dystrophy while they were still walking were enrolled in a non-randomized comparative study of the glucocorticoid deflazacort. The families of thirty boys elected for them to use glucocorticoid treatment and the families of twenty-four boys elected for them not to have this treatment. The boys were matched for important baseline characteristics including age and pulmonary function. Every four to six months, they were examined for the development of scoliosis, and the duration of follow-up for surviving patients was fifteen years. Because surgery was recommended for spinal curves measuring >20° on sitting posteroanterior radiographs, a curve of this magnitude was used as the definition for a patient developing scoliosis. Five boys (21%) in the non-treatment group and one boy (3%) in the glucocorticoid treatment group died. At the most recent follow-up, of the boys who survived, six (20%) in the glucocorticoid treatment group and twenty-two (92%) in the non-treatment group developed scoliosis and underwent spinal surgery. After fifteen years of follow-up, the survivorship analysis (avoiding surgery) was 78% (95% confidence interval, 57% to 89%) in the treatment group and 8.3% (95% confidence interval, 0.8% to 28%) in the non-treatment group. Significance (p = 5.8 × 10(-7)) was calculated with log-rank and chi-square tests. None of the patients in the glucocorticoid group developed scoliosis after ten years of deflazacort treatment.

The purpose of this study was to investigate the reliability of photogrammetry in the measurement of the postural deviations in individuals with idiopathic scoliosis. Twenty participants with scoliosis (17 women and three men), with a mean age of 23.1 ± 9 yrs, were photographed from the posterior and lateral views. The postural aspects were measured with CorelDRAW software. High inter-rater and test-retest reliability indices were found. It was observed that with more severity of scoliosis, greater were the variations between the thoracic kyphosis and lumbar lordosis measures obtained by the same examiner from the left lateral view photographs. A greater body mass index (BMI) was associated with greater variability of the trunk rotation measures obtained by two independent examiners from the right, lateral view (r = 0.656; p = 0.002). The severity of scoliosis was also associated with greater inter-rater variability measures of trunk rotation obtained from the left, lateral view (r = 0.483; p = 0.036). Photogrammetry demonstrated to be a reliable method for the measurement of postural deviations from the posterior and lateral views of individuals with idiopathic scoliosis and could be complementarily employed for the assessment procedures, which could reduce the number of X-rays used for the follow-up assessments of these individuals.

To determine overall, test-retest and inter-rater reliability of posture indices among persons with idiopathic scoliosis. A reliability study using two raters and two test sessions. Tertiary care paediatric centre. Seventy participants aged between 10 and 20 years with different types of idiopathic scoliosis (Cobb angle 15 to 60°) were recruited from the scoliosis clinic. Based on the XY co-ordinates of natural reference points (e.g., eyes) as well as markers placed on several anatomical landmarks, 32 angular and linear posture indices taken from digital photographs in the standing position were calculated from a specially developed software program. Generalisability theory served to estimate the reliability and standard error of measurement (SEM) for the overall, test-retest and inter-rater designs. Bland and Altman's method was also used to document agreement between sessions and raters. In the random design, dependability coefficients demonstrated a moderate level of reliability for six posture indices (ϕ=0.51 to 0.72) and a good level of reliability for 26 posture indices out of 32 (ϕ≥0.79). Error attributable to marker placement was negligible for most indices. Limits of agreement and SEM values were larger for shoulder protraction, trunk list, Q angle, cervical lordosis and scoliosis angles. The most reproducible indices were waist angles and knee valgus and varus. Posture can be assessed in a global fashion from photographs in persons with idiopathic scoliosis. Despite the good reliability of marker placement, other studies are needed to minimise measurement errors in order to provide a suitable tool for monitoring change in posture over time.

The scoliosis is a disease that affects the three-dimensional shape of the spine, which may occur at any stage of life but mainly arises from 10 years of age, and it is everyone's job (doctors, physiotherapists and teachers) responsible for managing the schoolchild to detect this spinal deformity. Therefore, we included a number of objectives in our study; first to detect the spinal disorder (scoliosis) in the school population from 8 to 12 years of Granada province; to establish the relationships between age groups and gender in people with scoliosis in the province of Granada; and finally to determine whether the occurrence of such changes have a greater impact on certain geographical areas in Granada province. Thus, this is a descriptive and cross-sectional study of a school population (n=2,956) in the province of Granada analyzed the positive clinical signs using the Adams Test on individuals with scoliosis. Of the 16 % (n=472) of schoolchildren who had scoliosis, 57.6 % (n=272) were male. The distribution of children from 8 to 12 years is fairly homogeneous with no differences seen (p=0.62) and highlight areas of higher incidence of scoliosis in zone 5 (Alpujarra-Valle of Lecrín). We conclude that there are no significant differences in scoliosis as regards age group (8 to 12 years), but there is an increasing trend towards the male gender. Differences can also be observed in the seven areas of study defined by work, environmental, genetic and consanguinity factors.

To explore the prevalence and distribution of abnormal vertebral pedicles in scoliosis secondary to neurofibromatosis type 1 (NF1-S) and to compare the abnormal vertebrae pedicles between dystrophic and nondystrophic scoliosis. Using computed tomography images, we carefully measured 2652 vertebral pedicles from 56 patients with NF1-S with dystrophic scoliosis and 22 patients with NF1-S with nondystrophic scoliosis. Pedicle morphology was classified as follows: type A, a cancellous channel of >4 mm; type B, a cancellous channel of 2 to 4 mm; type C, a cancellous channel of <2 mm with an entirely cortical channel of ≥2 mm; type D, a cortical channel of <2 mm; or type E, absent pedicle. Types B, C, D, and E were defined as abnormal. The total prevalence of abnormal vertebral pedicles in patients with NF1-S was as high as 67%, with type B comprising 39%, type C comprising 22%, type D comprising 4%, and type E comprising 2%. A significantly greater rate of abnormal pedicles was found in dystrophic scoliosis compared with nondystrophic scoliosis (70% vs. 59%, P < 0.0001). The upper thoracic spine (87%) is the most concentrated region of abnormal pedicles compared with the lower thoracic (73%) and lumbar spine (34%). There is a significantly high prevalence of abnormal pedicles in patients with NF1-S and an increased rate of abnormal pedicles in dystrophic scoliosis compared with nondystrophic ones. The described pedicle classification system could serve as an objective tool to guide preoperative assessment. Copyright © 2017 Elsevier Inc. All rights reserved.

Progression of scoliosis in patients with spastic quadriplegia after the insertion of an intrathecal baclofen pump.

Ginsburg, Glen M; Lauder, Anthony J

2007-11-15

Medical and radiographic review of 19 consecutive patients with spastic quadriplegia before and after intrathecal baclofen pump insertion with special attention paid to progression of scoliosis. Many orthopedic surgeons who treat spastic quadriplegic patients have noticed a trend of marked scoliosis progression after the administration of intrathecal baclofen (ITB) via subcutaneous pump and catheter. The purpose of this study is to quantify scoliosis progression in this patient population before and after baclofen administration and compare this to published natural history data. The authors had noted rapid progression of scoliosis in spastic quadriplegic patients after intrathecal baclofen pump insertion. This had been noted at other centers, but no significant statistical analysis had been done comparing prepump to postpump scoliosis progression in these patients. To document the magnitude and rate of scoliosis progressions after the placement of an ITB pump, the charts and radiographs of 19 consecutive nonambulatory patients with spastic quadriplegia and an ITB pump were reviewed. To document the rate of scoliosis progression, each patient had at least 2 pre and 2 postpump insertion spinal radiographs made. All radiographs were made with the patients in the supine position without orthoses. A board-certified orthopedic surgeon reviewed these radiographs. Skeletal maturity was assessed using Risser grading. Catheter tip location and rate of baclofen administration were recorded. For 19 patients with complete radiographic data, average Cobb angles were 10.2 degrees before pump insertion and 25 degrees at an average of 20.9 months after pump insertion (P < 0.0001). These 19 patients had a mean rate of change in their Cobb angles of 1.825%/year before pump insertion and 10.95 degrees /year at an average of 23.9 months after pump insertion (P = 0.024). These results represent a 6-fold increase in the curve progression rate after pump insertion. There was no

We assessed preoperative curve elasticity in 49 consecutive patients with juvenile or adolescent idiopathic scoliosis who were operated on with Harrington distraction rods. Preoperatively, the curve was determined from posteroanterior radiographs taken in the standing position and in the supine position, with traction. In the latter, the radiographs were taken at the moment of maximal traction when one technician applied traction to the ankles and another to the wrists. The scoliotic curve in the 10 patients with juvenile scoliosis averaged 59 degrees and 32 degrees in the standing and supine positions with traction, respectively. Immediately postoperatively, the curve averaged 19 degrees. 39 patients with adolescent scoliosis had a scoliotic curve which averaged 58 degrees in the standing position and 32 degrees in the supine position with traction. The mean postoperative measurement was 21 degrees. These findings suggest that manual traction is a simple and reliable means of predicting the minimal correction of the scoliotic curve to be expected, using Harrington distraction rods.

Radiation enteritis and radiation scoliosis

Any patient with radiation scoliosis should be suspected of having a visceral lesion as well. Chronic radiation enteritis may be manifested by intestinal obstruction, fistulas, perforation, and hemorrhage. Intestinal obstruction is the most common complication, and must be differentiated from postoperative cast or from spinal-traction syndrome. Obstruction that does not respond promptly to conservative measures must be treated surgically. Irradiated bowel is ischemic, and necrosis with spontaneous perforation can only be avoided with early diagnosis and surgical intervention.

An ideal animal model has always been the key to research the pathogenesis and treatment of adolescent idiopathic scoliosis (AIS), while available methods have obvious disadvantages. The deficiency of melatonin has been proved relating to AIS. In this research, we intended to apply Luzindole, the melatonin antagonist, in bipedal rat model, for the block of combination of melatonin and its receptor, to inhibit the melatonin effect, and then to understand whether this method can effectively improve the scoliosis rate of bipedal rat model, and investigate the role of melatonin in scoliosis. To investigate the feasibility of improving the success rate of bipedal rat scoliosis model via intraperitoneal injection of melatonin antagonist (Luzindole). A total of 60 3-weeks-old Sprague-Dawley rats were included in this study, and were divided into 3 groups (A, B and C). Each group included 20 rats. Osteotomy of the bilateral proximal humerus and proximal tailbone was performed in group A and group B; intraperitoneal injection of Luzindole (0.2 mg/kg) was performed in group A and group C. X-rays were taken before the surgery, 1 month after the surgery, 3 months after the surgery, and 6 months after the surgery, to calculate the Cobb's angle of the spine (>10° was considered scoliosis). The weight of every rat was also measured at the same time. Rats were euthanized 6 months after surgery to determine the calmodulin level in thrombocytes. The rate of scoliosis in group A (14/20) was significantly higher than those in group B (6/20) and group C (0/20) (P < 0.05). The differences in the weights of the 3 groups were non-significant; as were differences in the calmodulin level in thrombocytes. The application of the melatonin antagonist of Luzindole can improve the success rate of the bipedal rat scoliosis model. Meanwhile, this study indicates that a decreased melatonin level is not the primary cause of scoliosis, but that it may increase the likelihood and severity of

A person's image, which is determined through physical appearance, considerably affects self-esteem developed from early childhood. Scoliosis causes multiple trunk deformations that can affect a person's perception of the body. The aim of the study was to analyze the impact of scoliosis dimension and the degree of trunk deformation on the level of self-esteem and sexual functioning in women with idiopathic scoliosis. Thirty-six women diagnosed with idiopathic scoliosis were recruited to a prospective, double-blind, randomized controlled trial. The subjects were divided into two groups depending on the value of the Cobb angle. The level of self-esteem was determined by means of the Rosenberg Self-Esteem Scale (SES), whereas the sexual functioning was assessed via the Female Sexual Function Index (FSFI). The trunk deformations were specified with the Posterior Trunk Symmetry Index (POTSI). A statistically significant correlation was proved between the amount of points received in the Rosenberg scale evaluation and the POTSI index in Group A (R = -0.56, p = 0.04). Subjects with smaller deformations within the coronal plane had a higher level of self-confidence. The trunk asymmetries in the coronal plane may have a negative effect on women with scoliosis and their self-appraisal.

Background. The question of how to correct and rehabilitate scoliosis remains one of the most difficult problems of orthopaedics. Controversies continue to arise regarding various types of both symmetric and asymmetric scoliosis-specific therapeutic exercises. Objective. The aim of the present paper was to conduct an electromyographic assessment of functional symmetry of paraspinal muscles during symmetric and asymmetric exercises in adolescents with idiopathic scoliosis. Materials and Methods. The study was conducted in a group of 82 girls, mean age 12.4 ± 2.3 years with single- or double-major-idiopathic scoliosis, Cobb angle 24 ± 9.4°. The functional biopotentials during isometric work of paraspinal muscles in “at rest” position and during two symmetric and four asymmetric exercises were measured with the use of the Muscle Tester ME 6000 electromyograph. Results. In general, asymmetric exercises were characterised by larger differences in bioelectrical activity of paraspinal muscles, in comparison with symmetric exercises, both in the groups of patients with single-curve and double-curve scoliosis. Conclusion. During symmetric and asymmetric exercises, muscle tension patterns differed significantly in both groups, in comparison with the examination at rest, in most cases generating positive corrective patterns. Asymmetric exercises generated divergent muscle tension patterns on the convex and concave sides of the deformity. PMID:25258713

The International Scientific Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) produced its first guidelines in 2005 and renewed them in 2011. Recently published high-quality clinical trials on the effect of conservative treatment approaches (braces and exercises) for idiopathic scoliosis prompted us to update the last guidelines' version. The objective was to align the guidelines with the new scientific evidence to assure faster knowledge transfer into clinical practice of conservative treatment for idiopathic scoliosis (CTIS). Physicians, researchers and allied health practitioners working in the area of CTIS were involved in the development of the 2016 guidelines. Multiple literature reviews reviewing the evidence on CTIS (assessment, bracing, physiotherapy, physiotherapeutic scoliosis-specific exercises (PSSE) and other CTIS) were conducted. Documents, recommendations and practical approach flow charts were developed using a Delphi procedure. The process was completed with the Consensus Session held during the first combined SOSORT/IRSSD Meeting held in Banff, Canada, in May 2016. The contents of the new 2016 guidelines include the following: background on idiopathic scoliosis, description of CTIS approaches for various populations with flow-charts for clinical practice, as well as literature reviews and recommendations on assessment, bracing, PSSE and other CTIS. The present guidelines include a total of 68 recommendations divided into following topics: bracing ( n  = 25), PSSE to prevent scoliosis progression during growth ( n  = 12), PSSE during brace treatment and surgical therapy ( n  = 6), other conservative treatments ( n  = 2), respiratory function and exercises ( n  = 3), general sport activities ( n  = 6); and assessment ( n  = 14). According to the agreed strength and level of evidence rating scale, there were 2 recommendations on bracing and 1 recommendation on PSSE that reached level of

The esophagus occasionally crosses the descending aorta at an unusually high level (3-5 cm inferior to the carina) in right-sided scoliosis. The purpose of this study was to analyze the mechanism of this finding. We prospectively evaluated thoracic CT scans in 30 patients with right-sided scoliosis. We assessed the alterations in the positions of the esophagus and the descending aorta by the thoracic deformity. The descending aorta followed the scoliotic curve of the spine in 26 (87%) patients. The esophagus followed the scoliotic curve of the spine in 14 (47%) patients and did not in 16 (53%). The anteroposterior diametermore » of the thorax in the former group was significantly smaller than that in the latter (p < 0.01). High level cross of both structures was identified in 14 (47%) patients, and all of them belonged to the group in which the esophagus did not follow the scoliotic curve of the spine. The unusual high level cross of the esophagus with the descending aorta occasionally seen in scoliosis is due to a difference in the positional alterations of the two structures resulting from the scoliosis. 6 refs., 3 figs.« less

The radiation exposure resulting from standard scoliosis radiographs was determined for eighteen adolescent girls. The risk of inducing breast cancer was estimated from the skin-exposure doses. The average skin exposure to the breasts was 59.6 millirads (0.59 mGy) for the anteroposterior radiograph. Assuming a total of twenty-two anteroposterior radiographs during a course of treatment, the cumulative exposure would result in a 1.35% relative increase in the risk of development of breast cancer. By utilizing collimation of the x-ray beam and proper selection of grids, films, and screens, the radiation risk of scoliosis radiographs is minimized.

Center of pressure (CoP) progression during level walking in subjects with Adolescents Idiopathic Scoliosis (AIS) was measured. Participants were divided into three groups according to scoliosis severity. CoP progression among groups was compared quantitatively and qualitatively. The results showed that scoliosis severity affects CoP progression significantly in the hind-foot and forefoot areas. This result indicated that spine alignment might affect the control of heel, ankle and toe rockers in the ankle-foot complex. The effects of scoliosis severity is mainly on the CoP of right foot plantar surface, indicating asymmetrical influence of IS on bilateral lower limb coordination during walking. These results might contribute to musculoskeletal complains over the apparatus within trunk-foot in the later lives of this population.

Familial or Sporadic Idiopathic Scoliosis – classification based on artificial neural network and GAPDH and ACTB transcription profile

PubMed Central

2013-01-01

Background Importance of hereditary factors in the etiology of Idiopathic Scoliosis is widely accepted. In clinical practice some of the IS patients present with positive familial history of the deformity and some do not. Traditionally about 90% of patients have been considered as sporadic cases without familial recurrence. However the exact proportion of Familial and Sporadic Idiopathic Scoliosis is still unknown. Housekeeping genes encode proteins that are usually essential for the maintenance of basic cellular functions. ACTB and GAPDH are two housekeeping genes encoding respectively a cytoskeletal protein β-actin, and glyceraldehyde-3-phosphate dehydrogenase, an enzyme of glycolysis. Although their expression levels can fluctuate between different tissues and persons, human housekeeping genes seem to exhibit a preserved tissue-wide expression ranking order. It was hypothesized that expression ranking order of two representative housekeeping genes ACTB and GAPDH might be disturbed in the tissues of patients with Familial Idiopathic Scoliosis (with positive family history of idiopathic scoliosis) opposed to the patients with no family members affected (Sporadic Idiopathic Scoliosis). An artificial neural network (ANN) was developed that could serve to differentiate between familial and sporadic cases of idiopathic scoliosis based on the expression levels of ACTB and GAPDH in different tissues of scoliotic patients. The aim of the study was to investigate whether the expression levels of ACTB and GAPDH in different tissues of idiopathic scoliosis patients could be used as a source of data for specially developed artificial neural network in order to predict the positive family history of index patient. Results The comparison of developed models showed, that the most satisfactory classification accuracy was achieved for ANN model with 18 nodes in the first hidden layer and 16 nodes in the second hidden layer. The classification accuracy for positive Idiopathic

Degenerative diseases are results of deterioration of cells and tissues with aging either by unhealthy lifestyle or normal senescence. The degenerative disease likely affects central nervous system and cardiovascular system to a great extent. Certain medications and therapies have emerged for the treatment of degenerative diseases, but in most cases bearing with poor solubility, lower bioavailability, drug resistance, and incapability to cross the blood-brain barrier (BBB). Hence, it has to be overcome with conventional treatment system; in this connection, nanotechnology has gained a great deal of interest in recent years. Moreover, nanotechnology and nanocarrier-based approach drug delivery system could revolutionize the treatment of degenerative diseases by faster absorption of drug, targeted interaction at specific site, and its release in a controlled manner into human body with minimal side effects. The core objective of this review is to customize and formulate therapeutically active molecules with specific site of action and without affecting other organs and tissues to obtain effective result in the improvement of quality of health. In addition, the review provides a concise insight into the recent developments and applications of nanotech and nanocarrier-based drug delivery for the treatment of various degenerative diseases.

It has been suggested that cancer incidence is high in subjects with scoliosis who are relatively more often exposed to X--ray for diagnosis and follow--up. X--ray is a kind of ionizing radiation and leads to formation of oxygen free radicals which are capable of damage to DNA, thus altered gen expression and mutation. p53 tumor suppressor gene plays a crucial role in the damage response. It controls the checkpoint of cell cycle and redirects the cell metabolism to either repair of damaged DNA or apoptosis as response to DNA damage. The aim of the present study was to examine serum levels of 8--Hydroxydeoxyguanosine (8--OHdG), a strongly mutagenic product of oxidative DNA damage, p53, superoxide dismutase (SOD) and glutathione peroxidase (G--Px), as antioxidant activity, in children with scoliosis who had got whole spine radiograph two times during the last year. A total of 31 children with adolescent idiopathic scoliosis and age--matched 21 healthy children were included in the study. Serum levels of 8--OHdG and p53 were measured with ELISA kits. SOD and G--Px activities were determined with spectrophotometric assays. Serum levels of 8--OHdG and p53 were found to be higher (P<0.001 and P<0.01, respectively), SOD activity was found to be lower (P<0.001) in the children with scoliosis as compared to age--matched controls. There was no significant difference between the groups for G--Px activity. Our data show that X--ray exposure causes increased 8--OHdG level, and decreased SOD activity, which both may reflect a tumor promoting condition. Increased p53 level may be interpreted as a compensatory effort of cell to X--ray mediated DNA damage.

Background. Compensation for abnormal alignment of body parts in scoliosis may occur above or below the pelvis. This manifests as dislocation of body parts or changes in the angular composition of the lower limbs. Compensation for unbalanced body arrangement through changes in pelvic tilt and lower limb joints are typically reflected in the gait pattern of the person with scoliosis. The aim of our research was to determine whether and how improper body arrangement in the frontal plane is reflected in the gait pattern of children and youth with lower degree scolioses. Material and method. Children and youth with scolioses of varying grade were examined. In addition to photogrammetric body posture examination, three-dimensional gait analysis was performed during particular gait phases. For each examined child the results of this analysis were compared to the posture parameters. Results. Varying signs of gait asymmetry were observed in the whole group of children and youth with scoliosis. The symptoms were connected with both general gait attributes (unisommetry and unisochrony) and further gait markers. The most obvious changes were observed in pelvis rotation during the swing phase and excessive pelvis elevation during the mid-stance phase. These deviations did not correlate significantly with the results of the static examination. Conclusions. The gait asymmetries observed in children and youth with low-grade scoliosis are non-specific, and probably depend on the individual capabilities of each person to compensate for deficiencies.

Surgical and conservative treatment of patients with congenital scoliosis: α search for long-term results

PubMed Central

2011-01-01

Background In view of the limited data available on the conservative treatment of patients with congenital scoliosis (CS), early surgery is suggested in mild cases with formation failures. Patients with segmentation failures will not benefit from conservative treatment. The purpose of this review is to identify the mid- or long-term results of spinal fusion surgery in patients with congenital scoliosis. Methods Retrospective and prospective studies were included, reporting on the outcome of surgery in patients with congenital scoliosis. Studies concerning a small numbers of cases treated conservatively were included too. We analyzed mid-term (5 to 7 years) and long-term results (7 years or more), both as regards the maintenance of the correction of scoliosis and the safety of instrumentation, the early and late complications of surgery and their effect on quality of life. Results A small number of studies of surgically treated patients were found, contained follow-up periods of 4-6 years that in the most cases, skeletal maturity was not yet reached, and few with follow-up of 36-44 years. The results of bracing in children with congenital scoliosis, mainly in cases with failure of formation, were also studied. Discussion Spinal surgery in patients with congenital scoliosis is regarded in short as a safe procedure and should be performed. On the other hand, early and late complications are also described, concerning not only intraoperative and immediate postoperative problems, but also the safety and efficacy of the spinal instrumentation and the possibility of developing neurological disorders and the long-term effect these may have on both lung function and the quality of life of children. Conclusions Few cases indicate the long-term results of surgical techniques, in the natural progression of scoliosis. Similarly, few cases have been reported on the influence of conservative treatment. In conclusion, patients with segmentation failures should be treated

This report documents the clinical testing of scanning beam digital radiography as an imaging method in patients with scoliosis. This type of digital imaging requires a skin exposure of only 2.4 mR (0.619 microC/kg) per image, compared with the lowest possible posteroanterior screen-film exposure of 10 mR (2.58 microC/kg) at the chest and 60 mR (15.48 microC/kg) at the lumbar spine. Digital radiographic and screen-film images were obtained on multiple test objects and 273 patients. Scoliosis measurements using screen-film radiographs and digital radiographs were comparable to within a mean difference of 1 degrees at many different degrees of severity. Themore » low-dose digital images were found to be useful and accurate for the detection and measurement of scoliosis after the first screen-film radiographs have excluded tumors and structural abnormalities.« less

The prognosis of children with progressive early onset scoliosis has improved considerably due to recent advances in surgical and non-surgical techniques and the understanding of the importance of preserving the thoracic space. Improvements in existing techniques and development of new methods have considerably improved the management of this condition. Derotational casting can be considered in children with documented progression of a <60° curve without previous surgical treatment. Both single and dual growing rods are effective, but the latter seem to offer better results. Hybrid constructs may be a better option in children who require a low-profile proximal anchor. The vertical expandable prosthetic titanium rib (VEPTR(®)) appears to be beneficial for patients with congenital scoliosis and fused ribs, and thoracic Insufficiency Syndrome. Children with medical comorbidities who may not tolerate repeated lengthenings should be considered for Shilla or Luque Trolley technique. Growth modulation using shape memory alloy staples or other tethers seem promising for mild curves, although more research is required to define their precise indications. Copyright © 2013 SECOT.

Non-surgical interventions for adolescents with idiopathic scoliosis remain highly controversial. Despite the publication of numerous reviews no explicit methodological evaluation of papers labeled as, or having a layout of, a systematic review, addressing this subject matter, is available. Analysis and comparison of the content, methodology, and evidence-base from systematic reviews regarding non-surgical interventions for adolescents with idiopathic scoliosis. Systematic overview of systematic reviews. Articles meeting the minimal criteria for a systematic review, regarding any non-surgical intervention for adolescent idiopathic scoliosis, with any outcomes measured, were included. Multiple general and systematic review specific databases, guideline registries, reference lists and websites of institutions were searched. The AMSTAR tool was used to critically appraise the methodology, and the Oxford Centre for Evidence Based Medicine and the Joanna Briggs Institute's hierarchies were applied to analyze the levels of evidence from included reviews. From 469 citations, twenty one papers were included for analysis. Five reviews assessed the effectiveness of scoliosis-specific exercise treatments, four assessed manual therapies, five evaluated bracing, four assessed different combinations of interventions, and one evaluated usual physical activity. Two reviews addressed the adverse effects of bracing. Two papers were high quality Cochrane reviews, Three were of moderate, and the remaining sixteen were of low or very low methodological quality. The level of evidence of these reviews ranged from 1 or 1+ to 4, and in some reviews, due to their low methodological quality and/or poor reporting, this could not be established. Higher quality reviews indicate that generally there is insufficient evidence to make a judgment on whether non-surgical interventions in adolescent idiopathic scoliosis are effective. Papers labeled as systematic reviews need to be considered in terms

Degenerative disease affecting the nervous system.

PubMed

Eadie, M J

1974-03-01

The term "degenerative disease" is one which is rather widely used in relation to the nervous system and yet one which is rarely formally and carefully defined. The term appears to be applied to disorders of the nervous system which often occur in later life and which are of uncertain cause. In the Shorter Oxford Dictionary the word degeneration is defined as "a change of structure by which an organism, or an organ, assumes the form of a lower type". However this is not quite the sense in which the word is applied in human neuropathology, where it is conventional to restrict the use of the word to those organic disorders which are of uncertain or poorly understood cause and in which there is a deterioration or regression in the level of functioning of the nervous system. The concept of degenerative disorder is applied to other organs as well as to the brain, and as disease elsewhere in the body may affect the nervous system, it seems reasonable to include within the topic of degenerative disorder affecting the nervous system those conditions in which the nervous system is involved as a result of primary degenerations in other parts of the body.

We aimed to provide a complex assessment of adult females with adolescent idiopathic scoliosis (AIS) after a minimum of 23 years after completed Milwaukee brace treatment. In the present study, a comparison between healthy female and AIS patients' perception of trunk disfigurement, self-image, mental health, pain level and everyday activity was made. Thirty AIS patients with a mean of 27.77 yrs (SD 3.30) after the treatment were included in the study. The control group consisted of 42 females, matching the age profile of the patient group. Study participants from both groups were examined using the same protocol, except for the radiological evaluation. Patients and healthy controls completed the Polish versions of the Scoliosis Research Society (SRS-22) and Spinal Appearance Questionnaire (SAQ). Patients additionally filled the Bad Sobberheim Stress Questionnaire-Deformity (BSSQ-Deformity) and Bad Sobberheim Stress Questionnaire-Brace (BSSQ-Brace). The study group's SAQ results differ significantly in regard to the total score and all individual domains, indicating better functioning among healthy controls. Except for the General domain (p = 0.002), among the remaining subscales the study group's results differed significantly at p<0.001. Considering SRS-22 results, it was revealed that the patient group scored higher, signaling better functioning with reference to pain level (p = 0.016), function/activity (p<0.001) and the total score (p<0.001). The findings add to the complexity of long-term effect evaluations of AIS, particularly amongst females treated with a Milwaukee brace. Long-term results were not conclusive in terms of nonverbal assessment of body image and emotional tension regarding the experiences of brace-wearing. Future patients can be reassured that scoliosis treated conservatively does not negatively affect everyday activity, pain level, childbearing and mental health.

There has been only one reported case of neuromuscular scoliosis following chronic inflammatory demyelinating polyneuropathy (CIDP). However, no cases of scoliosis that were treated with surgery secondary to CIDP have been previously described. A 16-year-old boy with CIDP was consultant due to the progression of scoliosis with the coronal curve of 86° from T8 to T12. Posterior correction and fusion with segmental pedicle screws were performed under intraoperative spinal cord monitoring with transcranial electric motor-evoked potentials. Although the latency period was prolonged and amplitude was low, the potential remained stable. Coronal curve was corrected from 86° to 34° without neurological complications. We here describe scoliosis associated with CIDP, which was successfully treated with surgery under intraoperative spinal cord monitoring. PMID:23311940

This report describes improved signs and symptoms of previously untreated symptomatic spinal deformity in an adult female diagnosed with moderately severe thoracic scoliosis at the age of .7 years. Current treatment initiated at the age of forty included massage therapy, manual traction, ischemic pressure, and comprehensive manipulative medicine (CMM). A left-right chest circumference inequity was reduced by >10 cm, in correlation with improved appearance of the ribcage deformity and a 40% reduction in magnitude of Cobb angle, which had been stable for 30 years. The changes occurred gradually over an eight-year period, with the most rapid improvement occurring during two periods when CMM was employed.

Cross-sectional measurement study. To analyze the score distribution of the Scoliosis Research Society (SRS)-22 questionnaire domains and items for patients with idiopathic scoliosis (IS) of all ages. Scoliosis-related quality-of-life questionnaires have demonstrated high ceiling effects in younger patients. However, the score distribution has not been examined thoroughly in other clinically relevant IS subgroups. The SRS-22 was completed by 173 females with IS. The proportions of ceiling effects, floor effects, of patients scoring greater than or equal to 4 out of 5 and the box plots of the score distribution for each domain and item were compared between subgroups. Subgroups were formed based on age (k = 4), management (k = 6), curve severity (k = 3), and curve type (k = 4). Domain ceiling effects varied between 0% and 23.1%. Domain floor effects were observed only for Self-image (<7%) and Satisfaction (<12%). Only Pain and Satisfaction showed moderate (>20%) ceiling effects. Ceiling effects for Pain and Mental Health decreased with increasing age (P < 0.05). Pain ceiling effects decreased and Satisfaction ceiling effects increased from least to most invasive management (P < 0.05), but no differences were found among Cobb severity or curve types subgroups. Of the 22 items, 9 had major (>or=50%) ceiling effects and 11 had moderate ceiling effects. Most subgroups (14/16) had 4 to 6 items with major ceiling effects. The following items had major ceiling effects in the majority of subgroups: Function, 9 and 15; Pain, 11 and 17; and Self-image, 14. Most SRS-22 domains had acceptable levels of ceiling effects (<20%) in the majority of the subgroups examined. However, more sensitive measurements may be needed to supplement the SRS-22 in assessing Pain in patients below 18 years or Satisfaction after surgery.

Background Recent reports have suggested a rotational strength weakness in rotations to the concave side in patients with idiopathic scoliosis. There have been no studies presenting normative values of female adolescent trunk rotational strength to which a comparison of female adolescents with idiopathic scoliosis could be made. The purpose of this study was to determine trunk rotational strength asymmetry in a group of female adolescents with AIS and a comparison group of healthy female adolescents without scoliosis. Methods Twenty-six healthy adolescent females served as the healthy group (HG) (average age 14 years) and fourteen otherwise healthy adolescent females with idiopathic scoliosis served as the idiopathic scoliosis group (ISG) (average age 13.5 years, average Cobb 28°). Participant's isometric trunk rotational strength was measured in five randomly ordered trunk positions: neutral, 18° and 36° of right and left pre-rotation. Rotational strength asymmetry was compared within each group and between the two groups using several different measures. Results The HG showed strength asymmetry in the 36° pre-rotated trunk positions when rotating towards the midline (p < 0.05). The ISG showed strength asymmetry when rotating towards the concavity of their primary curve from the neutral position (p < 0.05) and when rotating towards the concavity from the 18° (p < 0.05) and 36° (p < 0.05) concave pre-rotated positions. The ISG is significantly weaker than the HG when rotating away from the midline toward the concave (ISG)-left (HG) side from the concave/left pre-rotated 18° (p < 0.05) and 36° (p < 0.05) positions. Conclusion The AIS females were found to be significantly weaker when contracting toward their main curve concavity in the neutral and concave pre-rotated positions compared to contractions toward the convexity. These weaknesses were also demonstrated when compared to the group of healthy female adolescent controls. Possible mechanisms for the

The athletic activity of the adult U.S. population has increased markedly in the last 20 years. To evaluate the possible long-term effects of such activity on the cervical and lumbar spine, we studied a group of asymptomatic currently very active lifelong male athletes over age 40 (41-69 years old, av. age 53). Nineteen active, lifelong male athletes were studied with MRI and the results compared with previous imaging studies of other populations. An athletic history and a spine history were also taken. Evidence of asymptomatic degenerative spine disease was similar to that seen in published series of other populations. Degenerativemore » changes including disk protrusion and herniation, spondylosis, and spinal stenosis were present and increased in incidence with increasing patient age. In this group, all MRI findings proved to be asymptomatic and did not limit athletic activity. The incidence of lumbar degenerative changes in our study population of older male athletes was similar to those seen in other populations. 14 refs., 8 figs., 1 tab.« less

Traditionally, the treatment options for adolescent idiopathic scoliosis (AIS), the most common form of scoliosis, are exercises; in-patient rehabilitation; braces and surgery. The outcomes of treatments are usually compared with the natural history or observation (non-intervention). The aim of this paper was to provide a synopsis of all treatment options in the light of evidence based practice (EBP). A systematic review was carried out using the most encompassing databases available. Literature has been searched for the outcome parameter ''rate of progression'' and only prospective controlled studies that have considered the treatment versus the natural history have been included. The search strategy included the following terms: ''adolescent idiopathic scoliosis''; ''idiopathic scoliosis''; ''natural history''; ''observation''; ''physiotherapy''; ''physical therapy''; ''rehabilitation''; ''bracing''; ''orthotics'' and ''surgery''. Prospective short-term studies have been found to support outpatient physiotherapy. One prospective controlled study was found to support scoliosis in-patient rehabilitation (SIR). One prospective multi-centre study, a long-term prospective controlled study and a meta-analysis have been found to support bracing. No controlled study, neither short, mid nor long-term, was found to reveal any substantial evidence to support surgery as a treatment for this condition. There is some evidence supporting the conservative treatment for AIS. No substantial evidence has been found in terms of prospective controlled studies to support surgical intervention. In light of the unknown long-term effects of surgery, a randomised controlled trial (RCT) seems necessary. Due to the presence of evidence to support conservative treatments, a plan to compose a RCT for conservative treatment options seems unethical. But it is also important to conclude that the evidence for conservative treatments is weak in number and length.

Today most surgical treatment of spinal deformations is concentrated on invasive mechanical techniques with long operation times and major effects on the patient's mobility. The proposed minimally invasive technique using laser light for tissue ablation offers a possibility of gentle scoliosis treatment. It is thought that an early removal of the epiphysial growth zone on the convex side over several vertebrae results in a straightening of the spine. In a first evaluation, four different laser systems including argon ion, Nd:YAG (Q-switched), Nd:YAG (cw), and Ho:YAG laser were compared with respect to thermal damage to adjacent tissue, ablation rates, efficiency and laser handling. For in-vivo investigation, fresh lamb spine was used. Comparison showed that the Ho:YAG laser is the most appropriate laser for the given goal, providing efficient photoablation with moderate thermal effects on the adjacent tissue. In a second step the proposed minimally invasive operation technique was performed in in-vivo experiments on young foxhounds using 3D- thoracoscopic operation techniques. During these operations temperature mapping was done using fiber-optic fluorescent probes. After 12 months of normal growth the animals were sacrificed and x-ray as well as MRI was performed on the spine. First results show a positive effect of scoliotic growth in two cases. Being able to produce a scoliosis by hemiepiphysiodesis on the vertebra, It is thought that this technique is successful for a straightening of the spine on patients with scoliosis.

[Purpose] This study aimed to provide a predictable evaluation method for the progression of scoliosis in adolescents based on quick and reliable measurements using the naked eye, such as the calcaneal valgus angle of the foot, which can be performed at public facilities such as schools. [Subjects and Methods] Idiopathic scoliosis patients with a Cobb's angle of 10° or more (96 females, 22 males) were included in this study. To identify relationships between factors, Pearson's product-moment correlation coefficient was computed. The degree of scoliosis was set as a dependent variable to predict thoracic and lumbar scoliosis using ankle angle and physique factors. Height, weight, and left and right calcaneal valgus angles were set as independent variables; thereafter, multiple regression analysis was performed. This study extracted variables at a significance level (α) of 0.05 by applying a stepwise method, and calculated a regression equation. [Results] Negative correlation (R=-0.266) was shown between lumbar lordosis and asymmetrical lumbar rotation angles. A correlation (R=0.281) was also demonstrated between left calcaneal valgus angles and asymmetrical thoracic rotation angles. [Conclusion] Prediction of scoliosis progress was revealed to be possible through ocular inspection of the calcaneus and Adams forward bending test and the use of a scoliometer.

To evaluate the accuracy and the effect of drill guide template for pedicle screw placement in severe scoliosis. Eight patients with rigid scoliosis were enrolled, five males and three females, ranging from nine to 23 years old. A three-dimensional CT scan of the spine was performed and saved as a DICOM file type. The multi-level template was designed by Mimics software and manufactured according to the part of the most severe deformity. The drill template was placed on the corresponding vertebral surface. Pedicle screws were carefully inserted across the trajectory of the template. Postoperatively, the positions of the pedicle screws were evaluated by CT scan and graded for validation. No spinal cord injury or nerve damage occurred. All patients had satisfactory outcomes. The abnormalities and the measures observed during operation were the same as those found in the preoperative period. The position of the pedicle screws was accurate, according to the postoperative X-ray and CT scan. The rate of scoliosis correction was 60%. Compared with controls, surgery time, blood loss and radiation were significantly lower. With the application of multi-level template, the placement of pedicle screws shows high accuracy in scoliosis with shorter surgical time, less blood loss and less radiation exposure.

Purpose The aim of this study was to investigate the interobserver agreement of the Lenke and King classifications for adolescent idiopathic scoliosis, and to compare the results of surgery performed based on classification of the scoliosis according to each of these classification systems. Methods The study was conducted in Shohada Hospital in Tabriz, Iran, between 2009 and 2010. First, a reliability assessment was undertaken to assess interobserver agreement of the Lenke and King classifications for adolescent idiopathic scoliosis. Second, postoperative efficacy and safety of surgery performed based on the Lenke and King classifications were compared. Kappa coefficients of agreement were calculated to assess the agreement. Outcomes were compared using bivariate tests and repeated measures analysis of variance. Results A low to moderate interobserver agreement was observed for the King classification; the Lenke classification yielded mostly high agreement coefficients. The outcome of surgery was not found to be substantially different between the two systems. Conclusion Based on the results, the Lenke classification method seems advantageous. This takes into consideration the Lenke classification’s priority in providing details of curvatures in different anatomical surfaces to explain precise intensity of scoliosis, that it has higher interobserver agreement scores, and also that it leads to noninferior postoperative results compared with the King classification method.

A method of scoliosis imaging using segmented fields is presented. The method is advantageous for patients requiring serial radiographic monitoring, as it results in markedly reduced radiation doses to critical organs, particularly the breast. Absorbed dose to the breast was measured to be 8.8 mrad (88 ..mu..Gy) for a full-field examination and 0.051 mrad (5.1 ..mu..Gy) for the segmented-field study. The segmented-field technique also results in improved image quality. Experience with 53 studies in 23 patients is reported.

[Treatment of early onset scoliosis : How far can we go?].

Recently, inconsistent definitions of early onset scoliosis (EOS) and a wide variety of treatment options have been observed. To clearly define the term EOS, to depict non-operative and operative treatment options, and to present the limitations of the boundaries of these techniques. Review of the literature, including conference presentations and expert opinions, in addition to personal experiences. Early onset scoliosis (EOS) refers to spine deformity that is present before 10 years of age, regardless of etiology. All existing operative treatment options share a high risk of complications. Therefore, non-operative treatment should act as a time-buying approach to postpone surgery. Awareness of treatment options and their specific indications, in addition to respecting each patient's individual needs and feasibilities, are crucial for the optimal outcome.

Adolescent idiopathic scoliosis is a complex spinal pathology characterized as a three-dimensional spine deformity combined with vertebral rotation. Various surgical techniques for correction of severe scoliotic deformity have evolved and became more advanced in applying the corrective forces. The objective of this study was to investigate the relationship between corrective forces acting on deformed rods and degree of scoliosis correction. Implant rod geometries of six adolescent idiopathic scoliosis patients were measured before and after surgery. An elasto-plastic finite element model of the implant rod before surgery was reconstructed for each patient. An inverse method based on Finite Element Analysis was used to apply forces to the implant rod model such that it was deformed the same after surgery. Relationship between the magnitude of corrective forces and degree of correction expressed as change of Cobb angle was evaluated. The effects of screw configuration on the corrective forces were also investigated. Corrective forces acting on rods and degree of correction were not correlated. Increase in number of implant screws tended to decrease the magnitude of corrective forces but did not provide higher degree of correction. Although greater correction was achieved with higher screw density, the forces increased at some level. The biomechanics of scoliosis correction is not only dependent to the corrective forces acting on implant rods but also associated with various parameters such as screw placement configuration and spine stiffness. Considering the magnitude of forces, increasing screw density is not guaranteed as the safest surgical strategy. Copyright © 2012 Elsevier Ltd. All rights reserved.

The etiology of adolescent idiopathic scoliosis is undetermined despite years of research. A number of hypotheses have been postulated to explain its development, including growth abnormalities. The irregular expression of growth hormone and insulin-like growth factor-1 (IGF-1) may disturb hormone metabolism, result in a gross asymmetry, and promote the progress of adolescent idiopathic scoliosis. Initial association studies in complex diseases have demonstrated the power of candidate gene association. Prior to our study, 1 study in this field had a negative result. A replicable study is vital for reliability. To determine the relationship of growth hormone receptor and IGF-1 genes with adolescent idiopathic scoliosis, a population-based association study was performed. Single nucleotide polymorphisms with potential function were selected from candidate genes and a distribution analysis was performed. A conclusion was made confirming the insufficiency of an association between adolescent idiopathic scoliosis and the single-nucleotide polymorphism of the growth hormone receptor and IGF-1 genes in Han Chinese.

The objective of this study was to explore whether differences in standing and sitting postures of youth with idiopathic scoliosis could be detected from quantitative analysis of digital photographs. Standing and sitting postures of 50 participants aged 10-20-years-old with idiopathic scoliosis (Cobb angle: 15° to 60°) were assessed from digital photographs using a posture evaluation software program. Based on the XY coordinates of markers, 13 angular and linear posture indices were calculated in both positions. Paired t-tests were used to compare values of standing and sitting posture indices. Significant differences between standing and sitting positions (p < 0.05) were found for head protraction, shoulder elevation, scapula asymmetry, trunk list, scoliosis angle, waist angles, and frontal and sagittal plane pelvic tilt. Quantitative analysis of digital photographs is a clinically feasible method to measure standing and sitting postures among youth with scoliosis and to assist in decisions on therapeutic interventions.

In dogs, degenerative joint diseases (DJD) have been shown to be associated with increased lactate dehydrogenase (LDH) activity in the synovial fluid. The goal of this study was to examine healthy and degenerative stifle joints in order to clarify the origin of LDH in synovial fluid. In order to assess the distribution of LDH, cartilage samples from healthy and degenerative knee joints were investigated by means of light and transmission electron microscopy in conjunction with immunolabeling and enzyme cytochemistry. Morphological analysis confirmed DJD. All techniques used corroborated the presence of LDH in chondrocytes and in the interterritorial matrix of healthy and degenerative stifle joints. Although enzymatic activity of LDH was clearly demonstrated in the territorial matrix by means of the tetrazolium-formazan reaction, immunolabeling for LDH was missing in this region. With respect to the distribution of LDH in the interterritorial matrix, a striking decrease from superficial to deeper layers was present in healthy dogs but was missing in affected joints. These results support the contention that LDH in synovial fluid of degenerative joints originates from cartilage. Therefore, we suggest that (1) LDH is transferred from chondrocytes to ECM in both healthy dogs and dogs with degenerative joint disease and that (2) in degenerative joints, LDH is released from chondrocytes and the ECM into synovial fluid through abrasion of cartilage as well as through enhanced diffusion as a result of increased water content and degradation of collagen.

The measurement of transverse pedicle width is still recommended for selecting a screw diameter despite being weakly correlated with the minimum pedicle diameter, except in the upper lumbar spine. The purpose of this study was to reveal the difference between the minimum pedicle diameter and conventional transverse or sagittal pedicle width in degenerative lumbar spines. A total of 50 patients with degenerative lumbar disorders without spondylolysis or lumbar scoliosis of >10° who preoperatively underwent helical CT scans were included. The DICOM data of the scans were reconstructed by imaging software, and the transverse pedicle width (TPW), sagittal pedicle width (SPW), minimum pedicle diameter (MPD), and the cephalocaudal inclination of the pedicles were measured. The mean TPW/SPW/MPD values were 5.46/11.89/5.09 mm at L1, 5.76/10.44/5.39 mm at L2, 7.25/10.23/6.52 mm at L3, 9.01/9.36/6.83 mm at L4, and 12.86/8.95/7.36 mm at L5. There were significant differences between the TPW and MPD at L3, L4, and L5 (p < 0.01) and between the SPW and MPD at all levels (p < 0.01). The MPD was significantly smaller than the TPW and SPW at L3, L4, and L5. The actual measurements of the TPW were not appropriate for use as a direct index for the optimal pedicle screw diameter at these levels. Surgeons should be careful in determining pedicle screw diameter based on plain CT scans especially in the lower lumbar spine.

The objective of the present study was to assess, at skeletal maturity, the efficacy of non-operative treatment by isolated nighttime brace in the prevention of progression of progressive idiopathic scoliosis of less than 25°. Isolated nighttime brace treatment is effective in the prevention of progression of mild progressive idiopathic scoliosis (Cobb<25°). A single-center retrospective study included 142 patients managed by nighttime brace for progressive idiopathic scoliosis with Cobb angle<25°, with assessment at skeletal maturity. Mean Cobb angle at start of treatment was 15.5° (range, 10-25°). Mean values for Cobb angle and sagittal parameters before treatment and at skeletal maturity were compared on Student t-test. Change in Cobb angle over time was also analyzed. Mean Cobb angle at skeletal maturity was 16.3°, showing significant increase over baseline (15.5°; P=0.04), although the difference was less than the uncertainty of measurement (±6°). In baseline Risser 0 or 1, mean change in Cobb angle at skeletal maturity (16.2°) was not significant (P=0.1). Cobb angle diminished in 26 cases (18%), increased in 24 (17%) and was unchanged in 92 (65%). The present study confirmed the efficacy of non-operative treatment by nighttime brace in mild progressive idiopathic scoliosis (<25°) in a large majority of cases. A nighttime brace thus seems to be an effective option for the treatment of adolescent scoliosis, ensuring a safe curve of around 20°. Level IV, retrospective study.

The DNA damage response (DDR) is a complex biological system activated by different types of DNA damage. Mutations in certain components of the DDR machinery can lead to genomic instability disorders that culminate in tissue degeneration, premature aging, and various types of cancers. Intriguingly, malfunctioning DDR plays a role in the etiology of late onset brain degenerative disorders such as Parkinson's, Alzheimer's, and Huntington's diseases. For many years, brain degenerative disorders were thought to result from aberrant neural death. Here we discuss the evidence that supports our novel hypothesis that brain degenerative diseases involve dysfunction of glial cells (astrocytes, microglia, and oligodendrocytes). Impairment in the functionality of glial cells results in pathological neuro-glial interactions that, in turn, generate a "hostile" environment that impairs the functionality of neuronal cells. These events can lead to systematic neural demise on a scale that appears to be proportional to the severity of the neurological deficit. Copyright © 2016 The Authors.

Degenerative diseases similarly as acute tissue injuries lead to massive cell loss and may cause organ failure of vital organs (e.g., heart, central nervous system). Therefore, they belong to a group of disorders that may significantly benefit from stem cells (SCs)-based therapies. Several stem and progenitor cell populations have already been described as valuable tools for developing therapeutic strategies in regenerative medicine. In particular, pluripotent stem cells (PSCs), including adult-tissue-derived PSCs, neonatal-tissue-derived SCs, embryonic stem cells (ESCs), and recently described induced pluripotent stem cells (iPSCs), are the focus of particular attention because of their capacity to differentiate into all the cell lineages. Although PSCs are predominantly envisioned to be applied for organ regeneration, they may be also successfully employed in drug screening and disease modeling. In particular, adult PSCs and iPSCs derived from patient tissues may not only be a source of cells for autologous therapies but also for individual customized in vitro drug testing and studies on the molecular mechanisms of disease. In this review, we will focus on the potential applications of SCs, especially PSCs i) in regenerative medicine therapies, ii) in studying mechanisms of disease, as well as iii) in drug screening and toxicology tests that are crucial in new drug development. In particular, we will discuss the application of SCs in developing new therapeutic approaches to treat degenerative diseases of the neural system and heart. The advantage of adult PSCs in all the above-mentioned settings is that they can be directly harvested from patient tissues and used not only as a safe non-immunogenic source of cells for therapy but also as tools for personalized drug screening and pharmacological therapies.

MRI signal distribution within the intervertebral disc as a biomarker of adolescent idiopathic scoliosis and spondylolisthesis.

Early stages of scoliosis and spondylolisthesis entail changes in the intervertebral disc (IVD) structure and biochemistry. The current clinical use of MR T2-weighted images is limited to visual inspection. Our hypothesis is that the distribution of the MRI signal intensity within the IVD in T2-weighted images depends on the spinal pathology and on its severity. Therefore, this study aims to develop the AMRSID (analysis of MR signal intensity distribution) method to analyze the 3D distribution of the MR signal intensity within the IVD and to evaluate their sensitivity to scoliosis and spondylolisthesis and their severities. This study was realized on 79 adolescents who underwent a MRI acquisition (sagittal T2-weighted images) before their orthopedic or surgical treatment. Five groups were considered: low severity scoliosis (Cobb angle ≤50°), high severity scoliosis (Cobb angles >50°), low severity spondylolisthesis (Meyerding grades I and II), high severity spondylolisthesis (Meyerding grades III, IV and V) and control. The distribution of the MRI signal intensity within the IVD was analyzed using the descriptive statistics of histograms normalized by either cerebrospinal fluid or bone signal intensity, weighted centers and volume ratios. Differences between pathology and severity groups were assessed using one- and two-way ANOVAs. There were significant (p < 0.05) variations of indices between scoliosis, spondylolithesis and control groups and between low and high severity groups. The cerebrospinal fluid normalization was able to detect differences between healthy and pathologic IVDs whereas the bone normalization, which reflects both bone and IVD health, detected more differences between the severities of these pathologies. This study proves for the first time that changes in the intervertebral disc, non visible to the naked eye on sagittal T2-weighted MR images of the spine, can be detected from specific indices describing the distribution of the MR

Cross-sequential study design that used data from Texas Scottish Rite Hospital for Children (TSRHC). Examine anxiety symptoms and family experiences subsequent to school scoliosis screening (SSS) referrals. Use of SSS remains controversial. Prior research suggested that SSS programs may result in anxiety for both children and parents. Unfortunately, no study has examined the SSS referral processes and anxiety in families. Study consisted of 2 groups-patients/parents from TSRHC evaluated for Adolescent Idiopathic Scoliosis (AIS) (n = 27) and control participants/parents (n = 27) between ages 9 and 17. All participants completed the primary outcome measure (State-Trait Anxiety Inventory) before and after the scoliosis evaluation or controlled wait time. Parents also rated experience and satisfaction with SSS. Compared with the control group, children/parents in patient group experienced significantly elevated levels of state-anxiety at preappointment. Children/parents in the patient group not diagnosed with AIS experienced a significant decline in state-anxiety. Children/parents in the patient group diagnosed with AIS continued to report elevated levels of anxiety. The control group remained consistent, reporting of low levels of anxiety pre to post. More than half (55.5%) of families indicated they received no information from the school about scoliosis. A third of the families who received information indicated it did not adequately address their concerns. Nonetheless, most families reported overall satisfaction with SSS. This study suggested that children and parents referred through the SSS program experienced significantly elevated levels of state-anxiety. This supports the subjective concerns of anxiety experiences in families voiced by researchers previously. However, families deemed the costs of the SSS referral process as worth the benefits. Though challengers of SSS programs were accurate in observing anxiety in families, it may not constitute

Study Design Longitudinal radiographic study of patients with progressive idiopathic scoliosis. Objective To determine the relative contributions of vertebral and disc wedging to the increase in Cobb angle during 3 phases of adolescent skeletal growth and maturation. Summary of Background Data Both disc wedging and vertebral body wedging are found in progressive scoliosis, but their relative contribution to curve progression over time is unknown. Which occurs first is important for understanding how scoliosis progresses and for developing methods to halt progression. Previous studies have not properly identified maturity and provide conflicting results. Methods Eighteen girls were followed through their adolescent growth spurt with serial spine and hand skeletal age radiographs. Each Cobb angle was divided into disc wedge angles and vertebral wedge angles. The corresponding hand radiographs provided a measure of maturity level, the Digital Skeletal Age (DSA). The disc versus bone contributions to the Cobb angle were then compared during 3 growth phases: prior to the growth spurt, during the growth spurt and after the growth spurt. Significance of relative changes was assessed with the Wilcoxon two-sided mean rank test. Results Prior to the growth spurt, there was no difference in relative contributions of the disc and the bone (3° vs 0°, p=0.38) to curve progression. During the growth spurt, the mean disc component progressed significantly more than that of the vertebrae (15° vs 0°, p=0.0002). This reversed following the growth spurt with the vertebral component progressing more than the disc (10° vs 0°, p=0.01). Conclusion Adolescent idiopathic scoliosis initially increases through disc wedging during the rapid growth spurt with progressive vertebral wedging occurring later. PMID:19940737

To compare the efficacy of three-dimensional (3D) Schroth exercises in patients with adolescent idiopathic scoliosis. A randomised-controlled study. An outpatient exercise-unit and in a home setting. Fifty-one patients with adolescent idiopathic scoliosis. Forty-five patients with adolescent idiopathic scoliosis meeting the inclusion criteria were divided into three groups. Schroth's 3D exercises were applied to the first group in the clinic and were given as a home program for the second group; the third group was the control. Scoliosis angle (Cobb method), angle of rotation (scoliometer), waist asymmetry (waist - elbow distance), maximum hump height of the patients and quality of life (QoL) (SRS-23) were assessed pre-treatment and, at the 6(th), 12(th) and 24(th) weeks. The Cobb (-2.53°; P=0.003) and rotation angles (-4.23°; P=0.000) significantly decreased, which indicated an improvement in the clinic exercise group compared to the other groups. The gibbosity (-68.66mm; P=0.000) and waist asymmetry improved only in the clinic exercise group, whereas the results of the other groups worsened. QoL did not change significantly in either group. According to the results of this study the Schroth exercise program applied in the clinic under physiotherapist supervision was superior to the home exercise and control groups; additionally, we observed that scoliosis progressed in the control group, which received no treatment. © The Author(s) 2015.

High correction bracing is the most effective conservative treatment for patients with scoliosis during growth. Still today braces for the treatment of scoliosis are made by casting patients while computer aided design (CAD) and computer aided manufacturing (CAM) is available with all possibilities to standardize pattern specific brace treatment and improve wearing comfort. CAD / CAM brace production mainly relies on carving a polyurethane foam model which is the basis for vacuuming a polyethylene (PE) or polypropylene (PP) brace. Purpose of this short communication is to describe the workflow currently used and to outline future requirements with respect to 3D printing technology. Description of the steps of virtual brace adjustment as available today are content of this paper as well as an outline of the great potential there is for the future 3D printing technology. For 3D printing of scoliosis braces it is necessary to establish easy to use software plug-ins in order to allow adding 3D printing technology to the current workflow of virtual CAD / CAM brace adjustment. Textures and structures can be added to the brace models at certain well defined locations offering the potential of more wearing comfort without losing in-brace correction. Advances have to be made in the field of CAD / CAM software tools with respect to design and generation of individually structured brace models based on currently well established and standardized scoliosis brace libraries.

To measure magnetic resonance imaging (MRI) parameters including relaxation times (T 1 ρ, T 2 ), magnetization transfer (MT) and diffusion parameters (mean diffusivity [MD], fractional anisotropy [FA]) of intervertebral discs in adolescents with idiopathic scoliosis, and to investigate the sensitivity of these MR parameters to the severity of the spine deformities. Thirteen patients with adolescent idiopathic scoliosis and three control volunteers with no history of spine disease underwent an MRI acquisition at 3T including the mapping of T 1 ρ, T 2 , MT, MD, and FA. The apical zone included all discs within the scoliotic curve while the control zone was composed of other discs. The severity was analyzed through low (<32°) versus high (>40°) Cobb angles. One-way analysis of variance (ANOVA) and agglomerative hierarchical clustering (AHC) were performed. Significant differences were found between the apical zone and the control zone for T 2 (P = 0.047), and between low and high Cobb angles for T 2 (P = 0.014) and MT (P = 0.002). AHC showed two distinct clusters, one with mainly low Cobb angles and one with mainly high Cobb angles, for the MRI parameters measured within the apical zone, with an accuracy of 0.9 and a Matthews correlation coefficient (MCC) of 0.8. Within the control zone, the AHC showed no clear classification (accuracy of 0.6 and MCC of 0.2). We successfully performed an in vivo multiparametric MRI investigation of young patients with adolescent idiopathic scoliosis. The MRI parameters measured within the intervertebral discs were found to be sensitive to intervertebral disc degeneration occurring with scoliosis and to the severity of scoliosis. J. Magn. Reson.

Weiner, Debra K; Sakamoto, Sara; Perera, Subashan; Breuer, Paula

2006-01-01

To develop a structured physical examination protocol that identifies common biomechanical and soft-tissue abnormalities for older adults with chronic low back pain (CLBP) that can be used as a triage tool for healthcare providers and to test the interobserver reliability and discriminant validity of this protocol. Cross-sectional survey and examination. Older adult pain clinic. One hundred eleven community-dwelling adults aged 60 and older with CLBP and 20 who were pain-free. Clinical history for demographics, pain duration, previous lumbar surgery or advanced imaging, neurogenic claudication, and imaging clinically serious symptoms. Physical examination for scoliosis, functional leg length discrepancy, pain with lumbar movement, myofascial pain (paralumbar, piriformis, tensor fasciae latae (TFL)), regional bone pain (sacroiliac joint (SIJ), hip, vertebral body), and fibromyalgia. Scoliosis was prevalent in those with (77.5%) and without pain (60.0%), but prevalence of SIJ pain (84% vs 5%), fibromyalgia tender points (19% vs 0%), myofascial pain (96% vs 10%), and hip pain (48% vs 0%) was significantly different between groups (P < .001). Interrater reliability was excellent for SIJ pain (0.81), number of fibromyalgia tender points (0.84), and TFL pain (0.81); good for scoliosis (0.43), kyphosis (0.66), lumbar movement pain (0.75), piriformis pain (0.71), and hip disease by internal rotation (0.56); and marginal for leg length (0.00) and paravertebral pain (0.39). Biomechanical and soft tissue pathologies are common in older adults with CLBP, and many can be assessed reliably using a brief physical examination. Their recognition may save unnecessary healthcare expenditure and patient suffering.

Spinal alignment in surgical, multisegmental, transpedicular correction of adolescent idiopathic scoliosis

2012-01-01

Summary The objective of this study was to discuss the variables influencing alignment mechanisms of the spine, with particular consideration of post-surgical alignment in adolescent idiopathic scoliosis. The analysis is based on information currently available in the literature, and on the authors’ own experience, which includes surgical material from over 2200 cases of idiopathic scoliosis. Over 50% of cases of adolescent idiopathic scoliosis are decompensated before surgical treatment. Spinal alignment is most significantly influenced by the position of the pelvis. Surgical restoration of lumbar lordosis is more important than attempting to restore thoracic kyphosis in the sagittal plane. The sagittal profile has an essential impact on spinal alignment. The same curves in the coronal plane can have various 3-dimensional configurations. Clinical difficulties in the assessment of thoracic kyphosis and lumbar lordosis result from the fact that they undergo constant change with age. Thoracic hypokyphosis diagnosed before surgery is a very frequent symptom of curve progression. The presence of proximal (thoraco-thoracic) and distal (thoraco-lumbar) junctional kyphosis is very important for planning the scope of spondylodesis. The natural tendency of the spine for alignment (compensation) after surgery nowadays occurs more naturally by applying derotational forces through pedicle screws, compared to the distraction devices (eg, Harrington rod) used in the past.

We studied the relationship between the age of reaching motor milestones, especially anti-gravity activities, and the age of development of pathological spinal curvatures in children with osteogenesis imperfecta (OI). We hypothesized that earlier achievement of anti-gravity motor milestones predicts a later development of pathological spinal curvatures. Ninety-six children participated in this retrospective study. The severity of the disease was classified according to Sillence into types I-IV. Spinal radiography was performed annually and spinal deformities were measured according to the Cobb angle. Scoliosis was defined as a Cobb angle exceeding 9 degrees. Pathological thoracic kyphosis was defined as a Cobb angle exceeding 40 degrees. The parents were asked to report the age at which the child achieved motor milestones, and data were checked against health care records. Thirty-seven of 96 children (39%) developed a scoliosis of more than 9 degrees. Nine of 96 children (9%) developed a pathological kyphosis. The age of developing scoliosis was significantly lower than the age of development of the pathological kyphosis (P=0.01). Bone mineral density was measured by dual energy X-ray absorptiometry (DEXA) in 53 children, 28 of whom developed scoliosis, and 25 of whom did not. The mean DEXA Z-score of the 28 children with scoliosis was significantly lower than that of the 25 children without (-5.2, SD 1.3 vs -3.2, SD 1.9; P-value <0.001). Children with OI type IV, but particularly OI type III, reached motor milestones much later than children with OI type I. The motor milestone "supported sitting" showed a significant inverse association with time of the first presence of scoliosis with a Cobb angle greater than 9 degrees (linear regression coefficient: -1.3, 95% confidence interval: -2.6 to -0.03). The age of achieving the motor milestones "lifting the head to 45 degrees in prone position", "rolling", and "supported-" and "unsupported standing" were not

2012-01-01

Background Early diagnosis of idiopathic scoliosis allows for observation and timely initiation of brace treatment in order to halt progression. School scoliosis screening programs were abolished in Norway in 1994 for lack of evidence that the programs improved outcome and for the costs involved. The consequences of this decision are discussed. Objectives To describe the detection, patient characteristics, referral patterns and treatment of idiopathic scoliosis at a scoliosis clinic during the period 2003–2011, when there was no screening and to compare treatment modalities to the period 1976–1988 when screening was performed. Methods Patient demographics, age at detection, family history, clinical and radiological charts of consecutive patients referred for scoliosis evaluation during the period 2003–2011, were prospectively registered. Patients were recruited from a catchment area of about 500000 teenagers. Maturity was estimated according to Risser sign and menarcheal status. Severity of pain was recorded by a verbal 5-point scale from no pain to pain at all times. Physical and neurological examinations were conducted. The detector and patient characteristics were recorded. Referral patterns of orthopedic surgeons at local hospitals and other health care providers were recorded. Patient data was obtained by spine surgeons. Treatment modalities in the current period were compared to the period 1976–1988. Results We registered 752 patients with late onset juvenile and adolescent idiopathic scoliosis from 2003–2011. There were 644 (86%) girls and 108 (14%) boys. Mean age at detection was 14.6 (7–19) years. Sixty percent had Risser sign ≥ 3, whilst 74% were post menarche with a mean age at menarche of 13.2 years. Thirty-one percent had a family history of scoliosis. The mean major curve at first consultation at our clinic was 38° (10°-95°). About 40% had a major curve >40°. Seventy-one percent were detected by patients, close relatives, and friends

Muscle imbalance has been suggested as implicated in the pathology of adolescent idiopathic scoliosis (AIS). The specific "pathomechanic" role of the paravertebral muscles as being scoliogenic (inducing scoliosis) or counteracting scoliosis in the initial development and maintenance of this spinal deformity has yet to be clarified in humans. In the present study, we investigated the radiographic changes of temporal paralysis using botulinum toxin A as localized injection therapy (ITB) in the psoas major muscle in AIS patients. Nine patients with AIS were injected one time with ITB using ultrasonic and EMG guidance in the selected spine muscles. Radiographic and clinical examinations were performed before and 6 weeks after the injection. Primary outcome parameters of radiological changes were analyzed using Wilcoxon signed-rank test and binomial test, and secondary outcome parameters of short- and long-term clinical effects were obtained. Significant radiological corrective changes were seen in the frontal plane in the thoracic and lumbar spine as well as significant derotational corrective change in the lumbar spine according to Cobb's angle measurements and to Nash and Moe's classification, respectively. No serious adverse events were detected at follow-up. In conclusion, this study demonstrated that the psoas major muscle do play a role into the pathology in adolescent idiopathic scoliosis by maintaining the curvature of the lumbar spine and thoracic spine.

Płaszewski, Maciej; Bettany-Saltikov, Josette

2014-01-01

Background Non-surgical interventions for adolescents with idiopathic scoliosis remain highly controversial. Despite the publication of numerous reviews no explicit methodological evaluation of papers labeled as, or having a layout of, a systematic review, addressing this subject matter, is available. Objectives Analysis and comparison of the content, methodology, and evidence-base from systematic reviews regarding non-surgical interventions for adolescents with idiopathic scoliosis. Design Systematic overview of systematic reviews. Methods Articles meeting the minimal criteria for a systematic review, regarding any non-surgical intervention for adolescent idiopathic scoliosis, with any outcomes measured, were included. Multiple general and systematic review specific databases, guideline registries, reference lists and websites of institutions were searched. The AMSTAR tool was used to critically appraise the methodology, and the Oxford Centre for Evidence Based Medicine and the Joanna Briggs Institute’s hierarchies were applied to analyze the levels of evidence from included reviews. Results From 469 citations, twenty one papers were included for analysis. Five reviews assessed the effectiveness of scoliosis-specific exercise treatments, four assessed manual therapies, five evaluated bracing, four assessed different combinations of interventions, and one evaluated usual physical activity. Two reviews addressed the adverse effects of bracing. Two papers were high quality Cochrane reviews, Three were of moderate, and the remaining sixteen were of low or very low methodological quality. The level of evidence of these reviews ranged from 1 or 1+ to 4, and in some reviews, due to their low methodological quality and/or poor reporting, this could not be established. Conclusions Higher quality reviews indicate that generally there is insufficient evidence to make a judgment on whether non-surgical interventions in adolescent idiopathic scoliosis are effective.

Degenerative aortic valve stenosis includes a range of disorder severity from mild leaflet thickening without valve obstruction, "aortic sclerosis", to severe calcified aortic stenosis. It is a slowly progressive active process of valve modification similar to atherosclerosis for cardiovascular risk factors, lipoprotein deposition, chronic inflammation, and calcification. Systemic signs of inflammation, as wall and serum C-reactive protein, similar to those found in atherosclerosis, are present in patients with degenerative aortic valve stenosis and may be expression of a common disease, useful in monitoring of stenosis progression.

It has been highlighted in both Poland and the United States of America (USA) that knowledge of idiopathic scoliosis (IS) among physiotherapy students is limited with respect to the 2011 International Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) guidelines. Early detection of scoliosis and correct initial management is essential in effective care, and thus physiotherapists should be aware of the basic criteria for diagnosis and indications for treatment. The aim of this study was to evaluate the basic knowledge of IS in physiotherapy students trained in the United Kingdom (UK). A previously designed and tested 10-question survey, including knowledge of the 2011 SOSORT guidelines, was transcribed onto an online-survey platform. Questions were designed to analyse knowledge of definition, cause, development, prevalence, diagnosis, treatment and bracing of scoliosis. All UK universities offering physiotherapy degrees were invited to participate, with the programme lead of each institution asked to distribute the questionnaire to all penultimate and final year physiotherapy students (bachelor's and master's degrees). The final number of students who received the study invitation is unknown. The survey link closed after 8 weeks of data collection. Two hundred and six students, split over 12 institutions, successfully completed the questionnaire. Analysis showed that 79% of students recognised when IS is likely to develop, yet only 52% recognised that IS's aetiology is unknown. Eighty-eight percent of students incorrectly defined IS as a 2-dimensional deformity, with only 24% successfully recognising the prevalence of IS within the scoliosis population. Just 12% knew the criteria for diagnosis; however, 93% were unable to recognise the appropriate treatment approach through therapeutic exercise. Finally, 54% of students managed to identify correctly when bracing is recommended for IS. In comparison to previous studies within the USA, students in

Scoliosis is the most widespread orthopaedic condition affecting both the children and the adolescents. The electrostatic field is known to promote the development of vibrations of varying strength in the biological tissues and their penetration rather deep into their interior. The objective of the present study was to elucidate the possibilities and practicability of the application of a low-frequency electrostatic field for the conservative treatment of grade I and II scoliosis in the children and to develop the scientifically sound substantiation for the use of this technique in the clinical practice. We examined and treated 94 children randomly divided into two groups (main and control) matched for the age and major clinical manifestation of the disease. All the patients received basic therapy. Those in the study group were additionally given low-frequency electrostatic therapy. The comparative analysis of the results of the treatment gave evidence that the application of a low-frequency electrostatic field for the conservative treatment of grade I and II scoliosis in the children resulted in the well apparent positive changes in their health status. These changes manifested themselves in the favourable dynamics of both the clinical symptoms of the disease and as the improvement of the topographic and thermographic characteristics. Of special importance is the alleviation of the symptoms of scoliotic deformation of the vertebral column under effect of the low-frequency electrostatic field. The present study has demonstrated that the application of the low-frequency electrostatic field significantly increases the effectiveness of the treatment of grade I and II scoliosis in the children and adolescents and promotes regression of this pathological condition.

A revised estimate of the risk of carcinogenesis from x-rays to scoliosis patients

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rao, P.S.; Gregg, E.C.

A considerable amount of concern has been felt recently for the risk of carcinogenesis from x-rays to scoliosis patients. This paper re-evaluates risk in quantitative terms by using some data measured by us and other data recently published in the literature. The risks are considerably smaller than had been estimated earlier. Compared with the natural incidence of cancer in the general population, the cumulative additional risk for scoliosis patients varies from 0.2% for breast carcinoma to 5% for leukemia.

Case report. We report a case of proximal junctional failure at the ankylosed, but not the mobile, junction after segmental instrumented fusion for degenerative lumbar kyphosis with ankylosing spinal disorder. Proximal junctional failure (PJF) and proximal junctional kyphosis (PJK) are important complications that occur subsequent to long-segment instrumentation for correction of adult spinal deformity. Thus far, most studies have focused on the mobile junction as a site at which PJK/PJF can occur, and little is known about the relationship between PJK/PJF and ankylosing spinal disorders such as diffuse idiopathic skeletal hyperostosis. The patient was an 82-year-old female with degenerative lumbar kyphosis. She had abnormal confluent hyperostosis in the anterior longitudinal ligaments from Th5 to Th10. The patient was treated operatively with spinal instrumented fusion from Th10 to the sacrum. Four weeks subsequent to initial surgery, the patient developed progressive lower extremity paresis caused by the uppermost instrumented vertebrae fracture (Th10) and adjacent subluxation (Th9). Extension of fusion to Th5 with decompression at Th9-Th10 was performed. However, the patient showed no improvement in neurological function. PJF can occur at the ankylosing site above the uppermost instrumented vertebrae after long-segment instrumentation for adult spinal deformity. PJF in the ankylosed spine may cause severe fracture instability and cord deficit. The ankylosed spine should be integrated into the objective determination of materials contributing to the appropriate selection of fusion levels. 3.

This study investigates outcome of scoliosis treatment for 11 children with Angelman syndrome (AS), with particular focus on activity, participation and the musculoskeletal factors that may affect these outcomes. Retrospective review of medical records, radiographs and questionnaires administered to caregivers of 11 children (8M:3F) with AS and scoliosis. Six underwent observational treatment during childhood and five underwent spinal fusion. The Activities Scale for Kids (ASKp) questionnaire was used to measure activity and participation. Questionnaire and radiographic data were recorded over a 2 year period. In the observational group, scoliosis increased from 31° to 46°. Mean ASKp decreased from 13.8 to 11.9 (p = 0.06). In the operative group, scoliosis decreased from 68° to 29°. Mean ASKp increased from 11.4 to 15.9 (p < 0.01). There was also a reduction in spinal-related pain and mean number of hospital admissions for chest infection. However, there was a 60% major complication rate. There was no difference in mobility, GMFCS level, feeding or communication in either group before or after treatment. In children with significant scoliosis and AS, spinal fusion was associated with a small improvement in activity and participation, reduction in pain and a decrease in frequency of severe chest infections. Non-operative treatment resulted in progression of scoliosis during childhood and decrease in activity.

Scoliosis brace design: influence of visual aesthetics on user acceptance and compliance.

PubMed

Law, Derry; Cheung, Mei-Chun; Yip, Joanne; Yick, Kit-Lun; Wong, Christina

2017-06-01

Adolescent idiopathic scoliosis is a common condition found in adolescents. A rigid brace is often prescribed as the treatment for this spinal deformity, which negatively affects user compliance due to the discomfort caused by the brace, and the psychological distress resulting from its appearance. However, the latter, which is the impact of visual aesthetics, has not been thoroughly studied for scoliosis braces. Therefore, a qualitative study with in-depth interviews has been carried out with 10 participants who have a Cobb angle of 20°-30° to determine the impact of visual aesthetics on user acceptance and compliance towards the brace. It is found that co-designing with patients on the aesthetic aspects of the surface design of the brace increases the level of user compliance and induces positive user perception. Therefore, aesthetic preferences need to be taken into consideration in the design process of braces. Practitioner Summary: The impact of visual aesthetics on user acceptance and compliance towards a rigid brace for scoliosis is investigated. The findings indicate that an aesthetically pleasing brace and the involvement of patients in the design process of the brace are important for increasing user compliance and addressing psychological issues during treatment.

The aim of this study was to compare transfusion requirements in patients before and after the introduction of tranexamic acid as standard in patients undergoing spinal surgery for idiopathic scoliosis in a national orthopaedic hospital. A retrospective chart review of 56 idiopathic scoliosis patients who underwent posterior spinal instrumentation and fusion between 2009 and 2013 at our institution. Preoperative, intraoperative, and postoperative data were measured. Patients who received tranexamic acid as standard (n = 31) showed a trend towards a decrease in transfusion requirements compared with those who received no tranexamic acid (n = 25). These patients had a statistically significant decrease in operative time (223 vs 188 min, p = 0.005), and estimated intraoperative blood loss was reduced by nearly 50% in the tranexamic acid group. They also had an associated reduced decrease in haemoglobin between preoperative and postoperative levels (4 vs 5 g/dL, p = 0.01). Since February 2012, no patient has required intraoperative or postoperative allogeneic blood product transfusion in this hospital. The routine use of antifibrinolytic medications in patients undergoing surgery for adolescent idiopathic scoliosis has effectively eliminated the need for allogeneic blood products.

Sagittal and transversal plane deformity in thoracic scoliosis.

The aim of the study was to assess the sagittal and transversal plane deformity of the spine in thoracic scoliosis by the mean of 3-D radiographic analysis. 46 patients admitted for surgery for thoracic idiopathic scoliosis underwent preoperative radiographic assessment. All patients presented the same pattern of the coronal plane deformity: single right thoracic curve (Lenke 1, King 3). Neither lumbar nor proximal thoracic structural curve were present. The Cobb angle varied from 41gamma to 77 gamma (mean 55,4 gamma +/- 8,6 gamma). Long cassette standing antero-posterior and lateral radiographs were analysed. Three-dimensional reconstruction with Rachis 91TM software was performed for each pair of radiographs. The following parameters were assessed: sagittal thoracic Cobb angle (Th4-Th12), upper thoracic kyphosis angle (Th5-Th8), lower thoracic kyphosis angle (Th9-Th12), superior and inferior hemi-curve sagittal angles, lumbar lordosis, sacral slope, sacral incidence, vertebral plate index, segmental vertebral axial rotation throughout the thoracic and lumbar spine. Results showed great variability of parameters assessed. The non-harmonious distribution of kyphosis was demonstrated in the thoracic spine. Local Th9-Th12 hypokyphosis and adjacent local Th5-Th8 hyperkyphosis constitute the most typical sagittal pathologies. So called normokyphotic curves were composed of one hyperkyphotic and one hypokyphotic zone. Th1-Th4 segment revealed two patterns of segmental rotation distribution: a purely compensatory curve with no vertebral axial rotation or a rotated curve presenting the morphology intermediate between Lenke 1 and Lenke 2 types (or King 3 and King 5). curves presenting the same coronal plane deformity differ in their morphology assessed in the two other planes; global thoracic kyphosis angle is a misleading parameter because it covers hypo- and hyperkyphotic zones; local distal thoracic (Th9-Th12) hypokyphosis is present in idiopathic thoracic scoliosis.

Bisphosphonates are widely used to treat children with osteogenesis imperfecta (OI), a bone fragility disorder that is most often caused by mutations in COL1A1 or COL1A2. However, it is unclear whether this treatment decreases the risk of developing scoliosis. We retrospectively evaluated spine radiographs and charts of 437 patients (227 female) with OI caused by mutations in COL1A1 or COL1A2 and compared the relationship between scoliosis, genotype and bisphosphonate treatment history. At the last follow-up (mean age 11.9 [SD: 5.9] years), 242 (55%) patients had scoliosis. The prevalence of scoliosis was highest in OI type III (89%), followed by OI type IV (61%) and OI type I (36%). Moderate to severe scoliosis (Cobb angle ≥25°) was rare in individuals with COL1A1 haploinsufficiency mutations but was present in about two fifth of patients with triple helical glycine substitutions or C-propeptide mutations. During the first 2 to 4years of bisphosphonate therapy, patients with OI type III had lower Cobb angle progression rates than before bisphosphonate treatment, whereas in OI types I and IV bisphosphonate treatment was not associated with a change in Cobb angle progression rates. At skeletal maturity, the prevalence of scoliosis (Cobb angle >10°) was similar in patients who had started bisphosphonate treatment early in life (before 5.0years of age) and in patients who had started therapy later (after the age of 10.0years) or had never received bisphosphonate therapy. Bisphosphonate treatment decreased progression rate of scoliosis in OI type III but there was no evidence of a positive effect on scoliosis in OI types I and IV. The prevalence of scoliosis at maturity was not influenced by the bisphosphonate treatment history in any OI type. Copyright © 2016 Elsevier Inc. All rights reserved.

The observations from 1985-1995 and till 2012 clarify that the development of so-called idiopathic scoliosis is connected with "gait" and habitual permanent "standing at ease" on the right leg. The scoliosis is "a result" of asymmetry of "function" - "changed" loading during gait and asymmetry in time during 'at ease' standing, more prevalent on the right leg. Every types of scoliosis is connected with the adequate "model of hips movements" [MHM] (Karski et al., 2006 [1]). This new classification clarifies the therapeutic approach to each types of scoliosis and provides the possibility to introduce causative prophylaxis.

Degenerative disease of the spine is a leading cause of back pain and radiculopathy, and is a frequent indication for spine MR imaging. Disc degeneration, disc protrusion/herniation, discarhtrosis, spinal canal stenosis, and facet joint arthrosis, as well as interspinous processes arthrosis, may require an MR imaging workup. This review presents the MR imaging patterns of these diseases and describes the benefit of the MR imaging in these indications compared with the other imaging modalities like plain radiographs or computed tomography scan.

Early, asymptomatic stage of degenerative joint disease in canine hip joints.

PubMed

Lust, G; Summers, B A

1981-11-01

The early stages of degenerative joint disease were investigated in coxofemoral joints from dogs with a hereditary predisposition to hip dysplasia. Alterations observed included mild nonsuppurative synovitis, increased volume of both synovial fluid and the ligamentum teres, and focal degenerative articular cartilage lesions. On radiologic examination, subluxation of the femoral head was seen, but only in the most severely affected joints. Synovial inflammation with increased synovial fluid and ligament volumes were indicators of early degenerative joint disease in dogs. These changes seemed to coincide with, or perhaps to precede, microscopic evidence for articular cartilage degeneration and occurred before radiologic abnormalities were detected.

2016-02-01

Infantile and juvenile scoliosis, among different types of spinal deformity, is still a challenge for pediatric orthopedic surgeons. The ideal treatment of infantile and juvenile scoliosis has not yet been identified as both clinicians and surgeons still face multiple challenges, including preservation of the thoracic spine, thoracic cage, lung growth and cardiac function without reducing spinal motion. Elongation, derotation, flexion (EDF) casting technique is a custom-made thoracolumbar cast based on a three dimensional correction concept. This cast offers three-dimensional correction and can control the evolution of the deformity in some cases. Spinal growth can be guided by EDF casting as it can influence the initially curved spine to grow straighter. This article aimed to provide a comprehensive review of how infantile and juvenile scoliosis can affect normal spine and thorax and how these deformities can be treated with serial EDF casting technique. A current literature review is mandatory in order to understand the principles of the serial EDF casting technique and the effectiveness of conservative treatment in young and very young patients.

To provide surgeons with alternatives to expensive specialized casting tables to allow local treatment of these children utilizing readily available materials present at most institutions. Casting for infantile scoliosis has become more popular as reports have shown promising results with this technique without the morbidity and complications associated with more invasive procedures. However, without a specialized casting table, treating these patients has been limited to a few centers throughout the country often causing patients to travel large distances to receive care. Three different alternatives to commercially available casting frames are presented. Requirements, setup, and techniques are discussed. Each surgeon has had success with each of these frames. These provide adequate support and traction while allowing enough access to the trunk to apply a well-molded cast. Cotrel/Metha casting for infantile scoliosis can be accomplished without a specialized table using commonly available equipment.

To determine if community equipoise exists concerning the effectiveness of bracing in adolescent idiopathic scoliosis. Bracing is the standard of care for adolescent idiopathic scoliosis despite the lack of strong reasearch evidence concerning its effectiveness. Thus, some researchers support the idea of a randomized trial, whereas others think that randomization in the face of a standard of care would be unethical. A random of Scoliosis Research Society and Pediatric Orthopaedic Society of North America members were asked to consider 12 clinical profiles and to give their opinion concerning the radiographic outcomes after observation and bracing. An expert panel was created from the respondents. They expressed a wide array of opinions concerning the percentage of patients within each scenario who would benefit from bracing. Agreement was noted concerning the risk due to bracing for post-menarchal patients only. : This study found a high degree of variability in opinion among clinicians concerning the effectiveness of bracing, suggesting that a randomized trial of bracing would be ethical.

Objective To demonstrate outer retinal tubulation (ORT) in various degenerative retinal disorders. Methods This was a retrospective review of the multimodal imaging of 29 eyes of 15 patients with various retinal dystrophies and inflammatory maculopathies manifesting ORT. The morphologic features of ORT and its evolution over time were analyzed using spectral-domain optical coherence tomography (SD-OCT) data. Results Outer retinal tubulation was identified as round or ovoid structures with hyper-reflective borders in pattern dystrophy (6 eyes), acute zonal occult outer retinopathy (5 eyes), retinitis pigmentosa (4 eyes), Stargardt disease (4 eyes), gyrate atrophy (2 eyes), choroideremia (2 eyes), and various other degenerative conditions. These structures appeared to develop from the invagination of photoreceptors at the junction of intact and atrophic outer retina. During follow-up, the number and distribution of ORT largely remained stable. As zones of atrophy enlarged, the frequency of ORT appeared to increase. The ORT structures were found in fewer than 10% of patients with retinitis pigmentosa, Stargardt, or pattern dystrophy. Conclusion Outer retinal tubulation is found in various degenerative retinal disorders that share in common damage to the outer retina and/or retinal pigment epithelium. The presence of ORT may be in an indicator of underlying disease stage and severity. PMID:23676993

Objective To evaluate the radiological and functional outcome of surgical treatment of adolescent idiopathic scoliosis using fourth-generation posterior spinal instrumentation at The Aga Khan University, Karachi, Pakistan. Design Case series. Place and duration of study The Aga Khan University Hospital after a minimum of 2 years postoperatively. Patients and methods A total of 20 patients with adolescent idiopathic scoliosis were recruited into the study and evaluated for radiological and functional outcome. The study period was from 2000 to 2005. Radiological outcome was assessed using Cobb angle measurement pre and postoperatively, hence assessing percentage correction. The lower instrumented vertebra was taken as the neutral vertebra and the level was recorded. Functional outcome was determined using the Scoliosis Research Society patient administered questionnaire. All patients were called to the clinic and asked to fill in the form. Those patients who were out of the city were mailed the forms and requested via telephone to complete and return. Results Of the 20 patients operated on, twelve were female and eight were male. The average age at operation was 12.7 years. The mean Cobb angle was 69° preoperatively and 20° postoperatively, representing a percentage correction of 71%. The average duration of follow-up was 3.6 years. There was one major complication involving neurological injury post-op and two minor complications involving wound infection. The average Scoliosis Research Society score (on a scale of 1–5, with 5 being best) for pain was 4.5, self-image was 4.2, functional status was 4.1, mental status was 3.8, and satisfaction was 4.4. There was no relationship between the percentage correction of scoliosis and the functional outcome. Those patients with a high preoperative Cobb angle tended to have a better outcome for functional and mental status postoperatively. There was no relation between the lower instrumented vertebra and functional outcome

Background The treatment of adolescent idiopathic scoliosis is contingent upon many variables. Simple observation is enough for less serious curvatures, but for very serious cases surgical intervention could be proposed. Between these there is a wide range of different treatments. Manual therapy is commonly used: the aim of this paper is to verify the data existing in the literature on the efficacy of this approach. Methods A systematic review of the scientific literature published internationally has been performed. We have included in the term manual therapy all the manipulative and generally passive techniques performed by an external operator. In a more specific meaning, osteopathic, chiropractic and massage techniques have been considered as manipulative therapeutic methods. We performed our systematic research in Medline, Embase, Cinhal, Cochrane Library, Pedro with the following terms: idiopathic scoliosis combined with chiropractic; manipulation; mobilization; manual therapy; massage; osteopathy; and therapeutic manipulation. The criteria for inclusion were as follows: Any kind of research; diagnosis of adolescent idiopathic scoliosis; patients treated exclusively by one of the procedures established as a standard for this review (chiropractic manipulation, osteopathic techniques, massage); and outcome in Cobb degrees. Results We founded 145 texts, but only three papers were relevant to our study. However, no one of the three satisfied all the required inclusion criteria because they were characterized by a combination of manual techniques and other therapeutic approaches. Conclusion The lack of any kind of serious scientific data does not allow us to draw any conclusion on the efficacy of manual therapy as an efficacious technique for the treatment of Adolescent idiopathic scoliosis.

Assessing functional outcome from patient-based outcomes questionnaires are essential to the evaluation of adolescent idiopathic scoliosis surgical treatment At the minimum follow-up of 2 years, 45 operated on adolescent idiopathic scoliosis patients were mailed the French version of the Scoliosis Research Society Outcome Instrument (SRS-22) questionnaires containing items on pain, activities of daily living, and satisfaction. Mean values of the SRS-22 domains were 3,66 for the Pain domain, 3,85 for the Self-perceived image domain, 4,32 for the Function domain, 3,52 for the Mental health domain and 4,12 for the Global satisfaction with management domain. Mean value of the global SRS-22 score was 3,88. We showed no differences in functional SRS-22 health status in patients according to the type of curve (Lenke classification). We showed statistically significant correlations between the gain of Cobb angle and Patients self-image and function domain scores. There was a statistically significant correlation between preoperative Cobb angle and patient satisfaction with management. Even if Function and Self-image scores in our patients are close to control group values, indicating good short to mid-term outcome of surgical treatment, scores for pain and mental health status were significantly lower in patients than controls. Long-term follow-up studies conducted by multiple surgeons over successive generations are mandatory to assess clinical significance of these differences. Level IV. Retrospective study.

Improvement of material property in spinal instrumentation has brought better deformity correction in scoliosis surgery in recent years. The increase of mechanical strength in instruments directly means the increase of force, which acts on bone-implant interface during scoliosis surgery. However, the actual correction force during the correction maneuver and safety margin of pull out force on each screw were not well known. In the present study, estimated corrective forces and pull out forces were analyzed using a novel method based on Finite Element Analysis (FEA). Twenty adolescent idiopathic scoliosis patients (1 boy and 19 girls) who underwent reconstructive scoliosis surgery between June 2009 and Jun 2011 were included in this study. Scoliosis correction was performed with 6mm diameter titanium rod (Ti6Al7Nb) using the simultaneous double rod rotation technique (SDRRT) in all cases. The pre-maneuver and post-maneuver rod geometry was collected from intraoperative tracing and postoperative 3D-CT images, and 3D-FEA was performed with ANSYS. Cobb angle of major curve, correction rate and thoracic kyphosis were measured on X-ray images. Average age at surgery was 14.8, and average fusion length was 8.9 segments. Major curve was corrected from 63.1 to 18.1 degrees in average and correction rate was 71.4%. Rod geometry showed significant change on the concave side. Curvature of the rod on concave and convex sides decreased from 33.6 to 17.8 degrees, and from 25.9 to 23.8 degrees, respectively. Estimated pull out forces at apical vertebrae were 160.0N in the concave side screw and 35.6N in the convex side screw. Estimated push in force at LIV and UIV were 305.1N in the concave side screw and 86.4N in the convex side screw. Corrective force during scoliosis surgery was demonstrated to be about four times greater in the concave side than in convex side. Averaged pull out and push in force fell below previously reported safety margin. Therefore, the SDRRT maneuver was

Scoliosis is a complex three-dimensional deformity with limited treatment options. Current treatments present potential problems that may be addressed with use of fusionless techniques for the correction of scoliosis. However, there are few data comparing the efficacy of different fusionless implant strategies in controlling scoliosis or on the integrity of rigid compared with flexible devices in an in vivo setting over time. The objective of this study was to compare the efficacy and integrity of rigid and flexible anterior thoracic tethers used to treat experimental scoliosis. Experimental scoliosis was created in twenty-four Spanish Cross-X female goats and was subsequently treated with either anterior shape memory alloy staples or anterior ligament tethers attached to bone anchors. Serial radiographs were analyzed to determine the efficacy of the implants in controlling scoliosis progression as well as the integrity of the implants at study completion. After the goats were killed, the implants were analyzed with use of three quantitative indices of implant integrity and implant pullout testing. Over the treatment period, scoliosis progressed from 77.3 degrees to 94.3 degrees in the goats treated with staples and was corrected from 73.4 degrees to 69.9 degrees in the goats treated with bone anchors, with loosening of eighteen of forty-two staples (two of the eighteen dislodged) and evidence of drift in two of forty-nine anchors. Histologic sections revealed a consistent halo of fibrous tissue around the staple tines but well-fixed bone anchors at all sites. Pullout testing demonstrated that bone anchors had greater strength than staples initially and at the study completion, with an increase in bone anchor fixation over the course of the study. In this scoliosis model, the flexible ligament tethers attached to bone anchors demonstrated greater efficacy and integrity than the more rigid shape memory alloy staples.

The authors present a new posterior correction technique consisting of simultaneous double-rod rotation using 2 contoured rods and polyaxial pedicle screws with or without Nesplon tapes. The purpose of this study is to introduce the basic principles and surgical procedures of this new posterior surgery for correction of adolescent idiopathic scoliosis. Through gradual rotation of the concave-side rod by 2 rod holders, the convex-side rod simultaneously rotates with the the concave-side rod. This procedure does not involve any force pushing down the spinal column around the apex. Since this procedure consists of upward pushing and lateral translation of the spinal column with simultaneous double-rod rotation maneuvers, it is simple and can obtain thoracic kyphosis as well as favorable scoliosis correction. This technique is applicable not only to a thoracic single curve but also to double major curves in cases of adolescent idiopathic scoliosis.

A quality-control Internet-based study using recognized quality scoring systems. To evaluate the quality of information available on the Internet. The quality of information available is of poor quality and unreliable, and this study was to determine if it has improved in line with the exponential increase in Internet-based information since the last time it was reviewed in 2005. To identify potential Web sites, the 5 most commonly accessed search engines were identified and a search for "scoliosis" was performed on each. The top 100 Web sites were reviewed. Each Web site was categorized according to its authorship and assessed using recognized scoring systems (Journal of American Medical Association [JAMA] and DISCERN criteria, scoliosis-specific content quality). The presence of the Health on the Net code, a reported quality-assurance marker, was noted. Forty-one unique Web sites were identified and analyzed. Five were academic, 11 were produced by physicians, 5 were commercial, 3 were nonphysician sites, 6 were attached to discussion groups or social media sites, 3 were media related, and 8 were not otherwise classifiable. There were significant differences noted between the authorship categories on the DISCERN score, JAMA benchmark criteria, and scoliosis-specific content quality score, (P = 0.001, <0.0001, and 0.009, respectively) with academic- and physician-related Web sites containing better-quality information. Internet sites with a Health on the Net code demonstrated higher-quality scoliosis-specific information than those without the code (P = 0.1368). The overall quality of information regarding scoliosis remains poor despite an exponential increase in the number of sites available. Patients need to be educated about appropriate Internet use-academic- and physician-provided sites have been shown to contain better-quality information. We have a potential role as clinicians to not only direct patients to appropriate sites but also to help in developing

The North American non-surgical standard of care for adolescent idiopathic scoliosis (AIS) includes observation and bracing, but not exercises. Schroth physiotherapeutic scoliosis-specific exercises (PSSE) showed promise in several studies of suboptimal methodology. The Scoliosis Research Society calls for rigorous studies supporting the role of exercises before including it as a treatment recommendation for scoliosis. To determine the effect of a six-month Schroth PSSE intervention added to standard of care (Experimental group) on the Cobb angle compared to standard of care alone (Control group) in patients with AIS. Fifty patients with AIS aged 10-18 years, with curves of 10°-45° and Risser grade 0-5 were recruited from a single pediatric scoliosis clinic and randomized to the Experimental or Control group. Outcomes included the change in the Cobb angles of the Largest Curve and Sum of Curves from baseline to six months. The intervention consisted of a 30-45 minute daily home program and weekly supervised sessions. Intention-to-treat and per protocol linear mixed effects model analyses are reported. In the intention-to-treat analysis, after six months, the Schroth group had significantly smaller Largest Curve than controls (-3.5°, 95% CI -1.1° to -5.9°, p = 0.006). Likewise, the between-group difference in the square root of the Sum of Curves was -0.40°, (95% CI -0.03° to -0.8°, p = 0.046), suggesting that an average patient with 51.2° at baseline, will have a 49.3° Sum of Curves at six months in the Schroth group, and 55.1° in the control group with the difference between groups increasing with severity. Per protocol analyses produced similar, but larger differences: Largest Curve = -4.1° (95% CI -1.7° to -6.5°, p = 0.002) and [Formula: see text] (95% CI -0.8 to 0.2, p = 0.006). Schroth PSSE added to the standard of care were superior compared to standard of care alone for reducing the curve severity in patients with AIS. NCT01610908.

Growing rod erosion through the lamina causing spinal cord compression in an 8-year-old girl with early-onset scoliosis.

Early-onset scoliosis often occurs by the age of 5 years and is attributed to many structural abnormalities. Syndromic early-onset scoliosis is considered one of the most aggressive types of early-onset scoliosis. Treatment starts with serial casting and bracing, but eventually most of these patients undergo growth-sparing procedures, such as a single growing rod, dual growing rods, or a vertical expandable titanium prosthetic rib. This case report aimed to describe an unusual complication of erosion of a growing rod through the lamina that caused spinal cord compression in an 8-year-old girl with early-onset scoliosis. This is a case report. A retrospective chart review was used to describe the clinical course and radiographic findings of this case after rod erosion into the spinal canal. The patient underwent successful revision surgery removing the rod without neurologic complications. Patients with syndromic early-onset scoliosis are more prone to progressive curves and severe rotational deformity. We believe that the severe kyphotic deformity in addition to the dysplastic nature of the deformity in this population may predispose them to this unusual complication. Copyright © 2016 Elsevier Inc.

Clinical evaluation of the postural balance in adolescent idiopathic scoliosis has been measured by sagittal vertical axis and frontal balance. The impact of the scoliotic deformity in three planes on balance has not been fully investigated. 47 right thoracic and left lumbar curves adolescent idiopathic scoliosis and 10 non-scoliotic controls were registered prospectively. 13 spinopelvic postural parameters were calculated from the 3-dimantional reconstructions of X-rays. 7 balance variables describing the position and sway of the center of pressure were recorded using a pressure mat. A regression analysis was used to predict sagittal vertical axis and frontal balance from the 7 balance variables. A canonical correlation analysis was performed between all the postural parameters and balance variables and the significant associations between the postural and balance variables were determined. sagittal vertical axis and frontal balance were not significantly associated with the position or sway of the center of pressure (p>0.05). Canonical correlation analysis showed significant associations between the postural variables in the 3 planes and center of pressure position (R 2 =0.81) and sway (R 2 =0.62), p<0.05. Frontal Cobbs, apical rotations, distal kyphosis, pelvic incidence, sacral slope, sagittal vertical axis, and frontal balance contributed to the postural balance in the cohort. The compensatory role of the pelvis and distal kyphosis in sagittal plane was underlined. Multidimensional analyses between the postural and balance variables showed the alignment of the thoracic, lumbar, and pelvis in the 3 planes, in addition to the global head-pelvic position impact on adolescent idiopathic scoliosis balance.

Prospective clinical series. To determine the effect of adhesive pads placed over the apex of scoliosis curves on curve correction 1) after the first cast and 2) after the final cast. Early-onset scoliosis is often effectively managed by serial casting. Properly localizing the apex of the molds with the cast in place is challenging. The authors explored the effectiveness of a novel technique: incorporation of adhesive pads placed over the major curve apex before Mehta casting. The 27 patients who received body casts (2000-2013) were divided into 2 groups: those without and with apical adhesive pads (5-6 layers of pads placed on the major curve's apex during casting): non-pad (NP) group (n = 12) and pad (P) group (n = 15), respectively. Groups were compared regarding the percentage of Cobb angle change from the first cast and curve correction to a Cobb angle of <25° with Student t and chi-square tests (significance was p < .05). The mean percentage of major first-cast curve correction was 39% ± 18% and 56% ± 17% in the NP and P groups, respectively. Of the 26 patients out of a cast, 11 (42%) had a Cobb angle of <25°: 3 (25%) and 8 (57%) in the NP and P groups, respectively. The mean differences between the 2 groups in percentage of major curve correction and this Cobb angle correction were significant: p = .023 and .005, respectively. Adhesive pads placed over major curve(s) during Mehta casting were effective in increasing the amount of major curve correction from the first cast for idiopathic early-onset scoliosis and in decreasing curves to <25° at final follow-up.

A reduced coracohumeral distance (CHD) is thought to be responsible for subcoracoid impingement. This only accounts for degenerative tendon tears. In traumatic tears, the subcoracoid space should be normal. The CHD in patients with traumatic subscapularis tendon tears is larger than that in patients with degenerative tears and does not differ from patients with an intact subscapularis tendon. Cohort study; Level of evidence, 3. A total of 83 patients with arthroscopically certified subscapularis tendon tears were included in the study. Forty-four patients had degenerative causes (group 1), and 39 had traumatic causes (group 2). The control group consisted of 20 patients with traumatic supraspinatus tendon tears and arthroscopically proven, intact subscapularis tendons (group 3). On preoperative axial magnetic resonance imaging, the distance between the CHD was measured, and the values of the 3 groups were compared using the t test. The mean (±SD) CHD in patients with degenerative subscapularis tendon tears was 8.6 ± 2.0 mm (range, 4.0-13.2 mm) and was significantly (P = .0003) smaller than that in patients with traumatic tears (10.2 ± 2.0 mm; range, 6.6-16.2 mm) or controls (10.4 ± 1.8 mm; range, 6.8-14.0 mm). The CHD of controls and patients with traumatic tears did not differ significantly (P = .7875). A CHD of less than 6 mm only occurred in patients with degenerative subscapularis tendon tears. The hypothesis that the CHD in patients with degenerative subscapularis tendon tears is significantly smaller than that in patients with traumatic tears or intact subscapularis tendons was confirmed. The CHD in patients with traumatic tears does not differ from that in controls. A CHD of less than 6 mm only occurs in patients with degenerative subscapularis tendon tears. © 2015 The Author(s).

Prospective longitudinal. Determine correlates of the peak height velocity (PHV) in girls with idiopathic scoliosis. Only identifiable retrospectively, the PHV is the most useful known maturity marker in idiopathic scoliosis. Clinically useful correlates are needed to make PHV timing helpful. A total of 24 immature girls with idiopathic scoliosis were followed with serial heights, sexual staging, skeletal ages, spinal radiographs, insulin-like growth factor (IGF)-1, IGF binding protein-3, dehydroepiandrosterone sulfate, estradiol, bone-specific alkaline phosphatase, and osteocalcin levels. These markers were correlated to PHV timing. There were 14 girls who had identifiable growth peaks that averaged 10.5 +/- 1.8 cm/y at age 11.7 +/- 1 years. At the PHV, all girls were Risser 0 with open triradiate cartilages. On a skeletal age radiograph, digital uncapped phalangeal epiphyses were indicative of pre-PHV and fused epiphyses of post-PHV. Capped but unfused epiphyses were indeterminate. Tanner stage 1 for breast strongly indicates pre-PHV. Stage 3 for breast and pubic hair occurred at or after the PHV, and stage 4 always occurred after PHV. Higher IGF-1 and estradiol levels after PHV are potentially discriminatory. The PHV occurs during Risser 0 with open triradiate cartilages. If triradiate cartilages are open, then Tanner stages, IGF-1, estradiol levels, and the appearance of the epiphyses on a skeletal age radiograph are useful in determining status before or after PHV.

Morphing the feature-based multi-blocks of normative/healthy vertebral geometries to scoliosis vertebral geometries: development of personalized finite element models.

PubMed

Hadagali, Prasannaah; Peters, James R; Balasubramanian, Sriram

2018-03-01

Personalized Finite Element (FE) models and hexahedral elements are preferred for biomechanical investigations. Feature-based multi-block methods are used to develop anatomically accurate personalized FE models with hexahedral mesh. It is tedious to manually construct multi-blocks for large number of geometries on an individual basis to develop personalized FE models. Mesh-morphing method mitigates the aforementioned tediousness in meshing personalized geometries every time, but leads to element warping and loss of geometrical data. Such issues increase in magnitude when normative spine FE model is morphed to scoliosis-affected spinal geometry. The only way to bypass the issue of hex-mesh distortion or loss of geometry as a result of morphing is to rely on manually constructing the multi-blocks for scoliosis-affected spine geometry of each individual, which is time intensive. A method to semi-automate the construction of multi-blocks on the geometry of scoliosis vertebrae from the existing multi-blocks of normative vertebrae is demonstrated in this paper. High-quality hexahedral elements were generated on the scoliosis vertebrae from the morphed multi-blocks of normative vertebrae. Time taken was 3 months to construct the multi-blocks for normative spine and less than a day for scoliosis. Efforts taken to construct multi-blocks on personalized scoliosis spinal geometries are significantly reduced by morphing existing multi-blocks.

In a lateral x-ray image of the cervical spine, degenerative changes are characterized by vertebral bodies that have indistinct boundaries and limited spacing between vertebrae. In this paper, we present a machine learning approach to detect and localize degenerative changes in lateral x-ray images of the cervical spine. Starting from a user-supplied set of points in the center of each vertebral body, we fit a central spline, from which a region of interest is extracted and image features are computed. A Random Forest classifier labels regions as degenerative change or normal. Leave-one-out cross-validation studies performed on a dataset of 103 patients demonstrates performance of above 95% accuracy.

The effectiveness of scoliosis screening programs: methods for systematic review and expert panel recommendations formulation

PubMed Central

2013-01-01

Background Literature on scoliosis screening is vast, however because of the observational nature of available data and methodological flaws, data interpretation is often complex, leading to incomplete and sometimes, somewhat misleading conclusions. The need to propose a set of methods for critical appraisal of the literature about scoliosis screening, a comprehensive summary and rating of the available evidence appeared essential. Methods To address these gaps, the study aims were: i) To propose a framework for the assessment of published studies on scoliosis screening effectiveness; ii) To suggest specific questions to be answered on screening effectiveness instead of trying to reach a global position for or against the programs; iii) To contextualize the knowledge through expert panel consultation and meaningful recommendations. The general methodological approach proceeds through the following steps: Elaboration of the conceptual framework; Formulation of the review questions; Identification of the criteria for the review; Selection of the studies; Critical assessment of the studies; Results synthesis; Formulation and grading of recommendations in response to the questions. This plan follows at best GRADE Group (Grades of Recommendation, Assessment, Development and Evaluation) requirements for systematic reviews, assessing quality of evidence and grading the strength of recommendations. Conclusions In this article, the methods developed in support of this work are presented since they may be of some interest for similar reviews in scoliosis and orthopaedic fields. PMID:23883346

The size asymmetry of cerebral hemispheres may predispose to head tilt and asymmetric blocking of the zygapophysial joints, potentially leading to the development of compensatory curvatures in the lower segments of the spine. To analyze the effects of spinal manipulation, maintained by an exercise program, on the progression of idiopathic adolescent scoliosis in 2 children aged 6 and 10. The scoliosis found was 16 and 60 degrees. For diagnosis and monitoring of therapy, we recorded qualitative parameters of shoulder asymmetry, axillary line asymmetry, and scapular angle position. Manual treatment consisted of the examinations of all sliding motion in zygapophysial joints and both sacroiliac joints and removing the limitations of the sliding motions according to the method of Karel Lewit. The treatment procedure consisted of 3 or 4 manipulations within 17 months and an exercise program. The manipulation effects were maintained by the exercise program. The exercises were done in 2 or 3 sessions weekly for a year. In both patients we observed that scoliosis decompensation was successfully stopped and the effects of the correction persisted for 10 years. Brain and head asymmetry may be only a transient state, predisposing to asymmetric blocking at the atlanto-occipital level. Removal of blocking may prevent curve progression in children who had adolescent idiopathic scoliosis. The manipulative therapy may also have a promising effect on retarding curve progression when used in skeletally immature patient.

Osteoarthritis (OA) is very common joint disease in the aging population. Main symptom of OA is accompanied by degenerative changes of articular cartilage. Raman spectroscopy is a label-free technique which enables to analyze molecular composition in degenerative cartilage. We generated an animal OA model surgically induced by knee joint instability and performed Raman spectroscopic analysis for the articular cartilage. In the result, Raman spectral data of the articular cartilage showed drastic changes in comparison between OA and control side. The relative intensity of phosphate band increases in the degenerative cartilage.

Despite its high prevalence, little is known about mechanisms of mitral regurgitation in degenerative mitral valve disease apart from the leaflet prolapse itself. Mitral valve is a complex structure, including mitral annulus, mitral leaflets, papillary muscles, chords, and left ventricular walls. All these structures are involved in physiological and pathological functioning of this valvuloventricular complex but up to now were difficult to analyze because of inherent limitations of 2-dimensional imaging. The advent of 3-dimensional echocardiography, computed tomography, and cardiac magnetic resonance imaging overcoming these limitations provides new insights into mechanistic analysis of degenerative mitral regurgitation. This review will detail the contribution of quantitative and qualitative dynamic analysis of mitral annulus and mitral leaflets by new imaging methods in the understanding of degenerative mitral regurgitation pathophysiology. © 2018 American Heart Association, Inc.

Pelvic obliquity and loss of sitting balance develop from progressive scoliosis in cerebral palsy (CP) and are indications for surgery. Our goal was to quantify pelvic asymmetry to help understand skeletal deformity in CP and its surgical correction. We assessed pelvic angles and transverse plane symmetry in 27 consecutive patients with scoliosis and severe CP who had undergone computed tomography for spinal surgery (subjects). The program used allowed measurement of angles in the true transverse plane, compensating for any obliquity present. Measurements included angles of the upper and lower ilium with respect to the sacrum, acetabular anteversion, and sacroiliac joint angles. We compared subject measurements with those of 20 age-matched controls and used Student t test to determine whether subjects had greater asymmetry and if the asymmetry direction was correlated with the adducted hip and/or the scoliosis in subjects with windswept hips. Subjects had significantly more iliac angle asymmetry (P=0.01) and asymmetry of at least 10 degrees in these categories: upper ilium, 15 (mean difference, 18); above sciatic notch, 14 (mean difference, 17); just below sciatic notch, 15 (mean difference, 19); sacroiliac joint, 5; and acetabular anteversion, 6. No control had asymmetry greater than 10 degrees. Comparing subjects with and without windswept hips, the former had more asymmetrical upper iliac angles. In 16 subjects with windswept hips, the scoliosis curve convexity was ipsilateral to the more internally rotated ilium. In 4 of the 5 subjects with severely windswept hips, the side of the adducted hip had more inward iliac rotation than did the contralateral (abducted) hip. Transverse pelvic asymmetry, a little-recognized deformity in patients with severe CP, is most pronounced above the acetabulum and is more common in patients with windswept hips. Spine surgeons should be aware of such asymmetry because it may make iliac fixation challenging and account for some

Serial cast correction is a popular treatment option for progressive infantile scoliosis. Body casting can lead to chest and abdominal expansion restriction and result in decreased chest wall compliance. There are no studies evaluating the effects of casting on ventilation in infantile scoliosis. This study examines changes in peak inspiratory pressure (PIP) during serial casting for infantile scoliosis. We retrospectively reviewed data obtained from 37 serial Cotrel elongation, derotation, and flexion cast corrections in patients with infantile scoliosis. Patient demographics, radiographic measurements, and anesthesia data were recorded. Anesthesia technique was standardized: children were intubated with rigid endotracheal tubes (ETTs); tidal volume was held constant at 8 to 10 cm(3)/kg using volume control ventilation; and PIP was recorded at baseline, after cast application before window cutout, and after window cutout before extubation. Any complications were documented. We assessed the PIP changes with a repeated measures analysis of variance (ANOVA). The mean age at first casting was 21.8 months (range, 12 to 42 mo) and mean follow-up since first casting was 22.4 months (range, 13 to 40 mo) with mean major Cobb angle of 53±15 degrees. The mean PIP was 15.5±4.9 cm H(2)O before casting, 31.9±7.9 cm H(2)O after cast application, and 20.4±5.6 cm H2O after making windows. There was a 106% increase after casting and 32% increase after window cutout from the baseline PIP levels. There was a significant difference in PIP on repeated measures ANOVA (P<0.0001). Intraoperatively, there was difficulty in maintaining ventilation during 2 procedures and 1 hypotensive episode. One patient developed hypoxemia after casting and another had delayed difficulty in breathing. Casting resulted in an increased PIP due to transient restrictive pulmonary process; after windows were cut out, the PIP reduced but not to baseline. In patients with underlying pulmonary disease, the

Idiopathic scoliosis (IS) is a three-dimensional deformity of the spine and trunk. The most common form involve adolescents. The prevalence is 2-3% of the population, with 1 out of 6 patients requiring treatment of which 25% progress to surgery. Physical and rehabilitation medicine (PRM) plays a primary role in the so-called conservative treatment of adolescents with IS, since all the therapeutic tools used (exercises and braces) fall into the PRM domain. According to a Cochrane systematic review there is evidence in favor of bracing, even if it is of low quality. Recently, a controlled prospective trial including a randomised arm gave more strength to this conclusion. Another Cochrane review shows that there is evidence in favor of exercises as an adjunctive treatment, but of low quality. Three meta-analysis have been published on bracing: one shows that bracing does not reduce surgery rates, but studies with bracing plus exercises were not included and had the highest effectiveness; another shows that full time is better than part-time bracing; the last focuses on observational studies following the Scoliosis Research Society (SRS) criteria and shows that not all full time rigid bracing are the same: some have the highest effectiveness, others have less than elastic and nighttime bracing. Two very important RCTs failed in recruitment, showing that in the field of bracing for scoliosis RCTs are not accepted by the patients. Consensuses by the international Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORT) show that there is no agreement among experts either on the best braces or on their biomechanical action, and that compliance is a matter of clinical more than patients' behavior (there is strong agreement on the management criteria to achieve best results with bracing). A systematic review of all the existing studies shows effectiveness of exercises, and that auto-correction is their main goal. A systematic review shows that there are no

The unexpected finding in 1959 by Marie-Jeanne Thillard that pinealectomy in young chickens gives way to spinal deformities was confirmed by the authors. In another experiment they found that injected melatonine to the chick at adequate dose and at the same time as surgery, lessen or even totally prevents the occurrence of deformities. On the other hand, at too low dose or delayed after pinealectomy melatonine injection, may not prevent the deformity which will be persisting or even increasing. In a subsequent series of experiments on the rat, pinealectomy results in decreasing the plasmatic amount of melatonine as well as giving way to spinal deformities. The nature of these deformities observed here is dependent on the stature between of the animal. The normal quadrupede rat develops after pinealectomy a standard scoliosis. Inversely the scoliotic deformity occurs when the animal has been forced to a bipede condition, which may be achieved by removing its forelimbs when baby, then forcing it to stand and remain in erect posture by high enough feeding. Melatonine depressing and erect position are in two conditions, when associated, likely to give way to experimental scoliosis. In human, a low nycthemeral level of plasmatic melatonine is correlated with progressive scoliosis. The level of platelets calmoduline, when is normally modulated by melatonine, has been proved by Kindsfater to be increased in progressive scoliosis. Then raises the hypothesis that human idiopathic scoliosis may be due to an inherited disorder of neuro-transmitters from neuro-hormonal origin, associated with bipedal condition, where an horizontal localized neuro-muscular imbalance starts and produces the scoliotic deformity of the fibro-elastic and bony structures axial spinal pilar.

Aim The purpose was to describe posture, ability to change position, and association between posture and contractures, hip dislocation, scoliosis, and pain in young adults with cerebral palsy (CP). Methods Cross-sectional data of 102 people (63 males, 39 females; age range 19–23y, median 21y) out of a total population with CP was analysed in relation to Gross Motor Function Classification System (GMFCS) levels I (n=38), II (n=21), III (n=13), IV (n=10), and V (n=20). The CP subtypes were unilateral spastic (n=26), bilateral spastic (n=45), ataxic (n=12), and dyskinetic CP (n=19). The Postural Ability Scale was used to assess posture. The relationship between posture and joint range of motion, hip dislocation, scoliosis, and pain was analysed using logistic regression and Spearman’s correlation. Results At GMFCS levels I to II, head and trunk asymmetries were most common; at GMFCS levels III to V postural asymmetries varied with position. The odds ratios (OR) for severe postural asymmetries were significantly higher for those with scoliosis (OR=33 sitting), limited hip extension (OR=39 supine), or limited knee extension (OR=37 standing). Postural asymmetries correlated to hip dislocations: supine (rs=0.48), sitting (rs=0.40), standing (rs=0.41), and inability to change position: supine (rs=0.60), sitting (rs=0.73), and standing (rs=0.64). Conclusions Postural asymmetries were associated with scoliosis, hip dislocations, hip and knee contractures, and inability to change position.

The treatment of patients with large adolescent idiopathic scoliosis curves has been associated with increased surgical complexity. The purpose of this study was to determine whether surgical correction of larger adolescent idiopathic scoliosis curves increased the utilization of health-care resources and to identify potential predictors associated with increased perioperative health-care resource utilization. A nested cohort of patients with adolescent idiopathic scoliosis with Lenke type 1A and 1B curves were identified from a prospective longitudinal multicenter database. Four perioperative outcomes were selected as the primary health-care resource utilization outcomes of interest: operative time, number of vertebral levels instrumented, duration of hospitalization, and allogeneic blood transfusion. The effect of curve magnitude on these outcomes was assessed with use of univariate and multivariate regression. Three hundred and twenty-five patients with a mean age of 15 ± 2 years were included. The mean main thoracic curve was 54.4° ± 7.8°. Larger curves were associated with longer operative time (p = 0.03), a greater number of vertebral levels instrumented (p = 0.0005), and the need for blood transfusion (with every 10° increase associated with 1.5 times higher odds of receiving a transfusion). In addition to curve magnitude, surgical center, bone graft method, and upper and lower instrumented levels were strong predictors of operative time (R2 = 0.76). The duration of hospitalization was influenced by the surgical center and intraoperative blood loss (R2 < 0.4), whereas the number of levels instrumented was influenced by the curve magnitude, curve correction percentage, upper instrumented vertebra, and surgical center (R2 = 0.64). Correction of larger curves was associated with increased utilization of perioperative health-care resources, specifically longer operative time, a greater number of vertebral levels instrumented, and higher odds of receiving a

Background Adolescent idiopathic scoliosis is a three-dimensional curvature of the spine of unknown cause that occurs in often otherwise fit young people. A complex surgical procedure is required for the most severe curves. Quantitative literature suggests scoliosis surgery improves patients' lives, while qualitative literature focuses on patients' concerns rather than their experience. Aims To explore how adolescents interpret their perioperative experience. Method Six participants, aged 15-18, were interviewed and transcripts were analysed. Findings Four themes were identified: shock, fears and worries; parental interaction; coping; and motivation and positivity. Conclusion Participants were reluctant to share concerns, however those they shared related more to fear of the unknown and lack of control than specific issues such as pain. Participants depended on their parents, especially their mothers, during the perioperative period, and they recognised their parents' stress. Participants coped well, were motivated and had a positive outlook.

The development of biomarkers for degenerative musculoskeletal conditions.

With an aging population, degenerative musculoskeletal conditions will become more prevalent with significantly increasing costs to society over the next several decades. The majority of these conditions are diagnosed radiographically, at which point the disease process is often more advanced and challenging to treat. The commonly available radiographic studies also do not adequately provide information as to the exact pain generator and findings often do not correlate either to patient symptoms or function. Personalized medicine involves formulating treatments based on a patient's own biology. The development of biological markers (biomarkers) pertaining to disease is a rapidly growing area within this field of medicine. For degenerative musculoskeletal conditions, biomarkers have the potential to provide an early non-invasive method of assessing the location and severity of tissue damage and presence of inflammation. By outlining mechanisms of disease they could allow the formulation of further treatment targets and through sub-categorizing patients into different groups based on their biomarker profile, one could provide more efficacious treatments for patients. The present article is a review of the development of biomarkers for these purposes specifically as they pertain to degenerative musculoskeletal conditions.

Cumulatively, degenerative disease is one of the most fatal groups of diseases, and it contributes to the mortality and poor quality of life in the world while increasing the economic burden of the sufferers. Oxidative stress and inflammation are the major pathogenic causes of degenerative diseases such as rheumatoid arthritis (RA), diabetes mellitus (DM), and cardiovascular disease (CVD). Although a number of synthetic medications are used to treat these diseases, none of the current regimens are completely safe. Phytochemicals (polyphenols, carotenoids, anthocyanins, alkaloids, glycosides, saponins, and terpenes) from natural products such as dietary fruits, vegetables, and spices are potential sources of alternative medications to attenuate the oxidative stress and inflammation associated with degenerative diseases. Based on in vitro , in vivo , and clinical trials, some of these active compounds have shown good promise for development into novel agents for treating RA, DM, and CVD by targeting oxidative stress and inflammation. In this review, phytochemicals from natural products with the potential of ameliorating degenerative disease involving the bone, metabolism, and the heart are described.

Several previous reports have elucidated the mortality and incidence of complications after pediatric scoliosis surgery using nationwide databases. However, all of these studies were conducted in North America. Hence, this study aimed to identify the incidence and risk factors for in-hospital mortality and morbidity in pediatric scoliosis surgery, utilizing the Diagnosis Procedure Combination database, a national inpatient database in Japan.We retrospectively extracted data for patients aged less than 19 years who were admitted between 01 June 2010 and 31 March 2013 and underwent scoliosis surgery with fusion. The primary outcomes were in-hospital death and postoperative complications, including surgical site infection, ischemic heart disease, acute renal failure, pneumonia, stroke, disseminated intravascular coagulation, pulmonary embolism, and urinary tract infection.We identified 1,703 eligible patients (346 males and 1,357 females) with a mean age of 14.1 years. There were no deaths among the patients. At least one postoperative complication was found in 49 patients (2.9%). The most common complication was surgical site infection (1.4%). The multivariable logistic regression analysis showed that male sex (odds ratio, 2.22; 95% confidence interval, 1.28-3.70), comorbid diabetes (7.00; 1.56-31.51), and use of allogeneic blood transfusion (3.43; 1.86-6.41) were associated with the occurrence of postoperative complications. The present nationwide study elucidated the incidence and risk factors for in-hospital mortality and morbidity following surgery for pediatric scoliosis in an area other than North America. Diabetes was identified for the first time as a risk factor for postoperative complications in pediatric scoliosis surgery.

ABSTRACT Objective: To evaluate the hormonal profile of patients with adolescent idiopathic scoliosis (AIS) and its relationship to the severity of the curvature and quality of life. Method: Patients with scoliosis (Cobb angle above 10°), of both genders, diagnosed after 10 years of age were included, excluding those who presented other condition that could lead to scoliosis. Serum levels of 25-hydroxyvitamin D (25-OHD), cortisol and gastrin were correlated with Cobb angle and quality of life, measured by the SRS-30 questionnaire. Results: The levels of 25-OHD decreased in 97% of patients. There was an inverse relationship between gastrin levels and quality of life (p = 0.016). Moreover, there was an inverse correlation between the value of Cobb angle and quality of life (p = 0.036). There were no changes in cortisol levels. There was no correlation between Cobb angle and any of the hormones measured. Conclusion: The patients had levels of 25-OHD diminished, strengthening the hypothesis of its involvement in the development of AIS. This study also suggests that increased gastrin levels may be associated with a worse quality of life in patients with AIS. Level of Evidence II, Diagnostic Study. PMID:28642644

The uncommon variant of degenerative hip joint disease, termed rapidly progressive osteoarthritis, and highlighted by severe joint space loss and osteochondral disintegration, is well established. We present a similar unusual subset in the lumbar spine termed destructive discovertebral degenerative disease (DDDD) with radiological features of vertebral malalignment, severe disc resorption, and "bone sand" formation secondary to vertebral fragmentation. Co-existing metabolic bone disease is likely to promote the development of DDDD of the lumbar spine, which presents with back pain and sciatica due to nerve root compression by the "bone sand" in the epidural space. MRI and CT play a complimentary role in making the diagnosis.

Objective To determine if community equipoise exists concerning the effectiveness of bracing in adolescent idiopathic scoliosis. Background Data Bracing is the standard of care for adolescent idiopathic scoliosis despite the lack of strong reasearch evidence concerning its effectiveness. Thus, some researchers support the idea of a randomized trial, whereas others think that randomization in the face of a standard of care would be unethical. Methods A random of Scoliosis Research Society and Pediatric Orthopaedic Society of North America members were asked to consider 12 clinical profiles and to give their opinion concerning the radiographic outcomes after observation and bracing. Results An expert panel was created from the respondents. They expressed a wide array of opinions concerning the percentage of patients within each scenario who would benefit from bracing. Agreement was noted concerning the risk due to bracing for post-menarchal patients only. Conclusions This study found a high degree of variability in opinion among clinicians concerning the effectiveness of bracing, suggesting that a randomized trial of bracing would be ethical.

Scoliosis is a common complication in children with cerebral palsy (CP). In these patients, surgical correction carries a high risk of complications. CP is also associated with gastrointestinal dysmotility such as delayed gastric emptying and gastro-oesophageal reflux. We describe 5 patients with CP in whom symptoms of gastric dysmotility clearly exacerbated after orthopaedic scoliosis surgery. They all showed persisting vomiting, nausea, bloating, weight loss, and anorexia necessitating total parental nutrition and/or jejunal feeding. This intensified nutritional support resulted in weight gain. Symptoms, however, persisted in half of the patients. The aetiology of these gastro-intestinal motility problems following scoliosis surgery remains unclear. Mechanical obstruction needs to be ruled out. Delayed gastric emptying may be due to postprandial antral hypomotility as a consequence of sympathic stimulation. Malnutrition could further aggravate gastrointestinal dysmotility. This complication should be taken into account when surgery for spinal deformities in CP patients is planned, especially in patients with pre-existing gastrointestinal motility problems. © Georg Thieme Verlag KG Stuttgart · New York.

Background The North American non-surgical standard of care for adolescent idiopathic scoliosis (AIS) includes observation and bracing, but not exercises. Schroth physiotherapeutic scoliosis-specific exercises (PSSE) showed promise in several studies of suboptimal methodology. The Scoliosis Research Society calls for rigorous studies supporting the role of exercises before including it as a treatment recommendation for scoliosis. Objectives To determine the effect of a six-month Schroth PSSE intervention added to standard of care (Experimental group) on the Cobb angle compared to standard of care alone (Control group) in patients with AIS. Methods Fifty patients with AIS aged 10–18 years, with curves of 10°-45° and Risser grade 0–5 were recruited from a single pediatric scoliosis clinic and randomized to the Experimental or Control group. Outcomes included the change in the Cobb angles of the Largest Curve and Sum of Curves from baseline to six months. The intervention consisted of a 30–45 minute daily home program and weekly supervised sessions. Intention-to-treat and per protocol linear mixed effects model analyses are reported. Results In the intention-to-treat analysis, after six months, the Schroth group had significantly smaller Largest Curve than controls (-3.5°, 95% CI -1.1° to -5.9°, p = 0.006). Likewise, the between-group difference in the square root of the Sum of Curves was -0.40°, (95% CI -0.03° to -0.8°, p = 0.046), suggesting that an average patient with 51.2° at baseline, will have a 49.3° Sum of Curves at six months in the Schroth group, and 55.1° in the control group with the difference between groups increasing with severity. Per protocol analyses produced similar, but larger differences: Largest Curve = -4.1° (95% CI -1.7° to -6.5°, p = 0.002) and Sum of Curves=−0.5° (95% CI -0.8 to 0.2, p = 0.006). Conclusion Schroth PSSE added to the standard of care were superior compared to standard of care alone for reducing the

Adolescent idiopathic scoliosis (AIS) may lead to physical and mental problems. It also can adversely affect patient satisfaction and the quality of life. In this study, we assessed the outcomes and satisfaction rate after surgical treatment of AIS using scoliosis research society-30 questionnaire (SRS-30). We enrolled 135 patients with AIS undergoing corrective surgery. Patients were followed for at least 2 years. We compared pre- and post-operative x-rays in terms of Cobb's angles and coronal balance. At the last visit, patients completed the SRS-30 questionnaire. We then assessed the correlation between radiographic measures, SRS-30 total score, and patient satisfaction. Cobb's angle and coronal balance improved significantly after surgery (P<0.001). The scores of functional activity, pain, self-image/cosmesis, mental health, and satisfaction were 27±4.3, 26±2.5, 33±5.2, 23±3.5, and 13±1.8, respectively. The total SRS-30 score was 127±13. Radiographic measures showed significant positive correlation with satisfaction and SRS-30 total scores. There was also a positive correlation between satisfaction and self-image/cosmesis domain scores. The greater the radiographic angles were corrected the higher the SRS-30 total score and patient satisfaction were. It is intuitive that the appearance and cosmesis is of most important factor associated with patient satisfaction.

Anterior Cervical Spine Surgery for Degenerative Disease: A Review

PubMed Central

SUGAWARA, Taku

Anterior cervical spine surgery is an established surgical intervention for cervical degenerative disease and high success rate with excellent long-term outcomes have been reported. However, indications of surgical procedures for certain conditions are still controversial and severe complications to cause neurological dysfunction or deaths may occur. This review is focused mainly on five widely performed procedures by anterior approach for cervical degenerative disease; anterior cervical discectomy, anterior cervical discectomy and fusion, anterior cervical corpectomy and fusion, anterior cervical foraminotomy, and arthroplasty. Indications, procedures, outcomes, and complications of these surgeries are discussed. PMID:26119899

Degenerative ataxias in children present a rare condition where effective treatments are lacking. Intensive coordinative training based on physiotherapeutic exercises improves degenerative ataxia in adults, but such exercises have drawbacks for children, often including a lack of motivation for high-frequent physiotherapy. Recently developed whole-body controlled video game technology might present a novel treatment strategy for highly interactive and motivational coordinative training for children with degenerative ataxias. We examined the effectiveness of an 8-week coordinative training for 10 children with progressive spinocerebellar ataxia. Training was based on 3 Microsoft Xbox Kinect video games particularly suitable to exercise whole-body coordination and dynamic balance. Training was started with a laboratory-based 2-week training phase and followed by 6 weeks training in children's home environment. Rater-blinded assessments were performed 2 weeks before laboratory-based training, immediately prior to and after the laboratory-based training period, as well as after home training. These assessments allowed for an intraindividual control design, where performance changes with and without training were compared. Ataxia symptoms were significantly reduced (decrease in Scale for the Assessment and Rating of Ataxia score, p = 0.0078) and balance capacities improved (dynamic gait index, p = 0.04) after intervention. Quantitative movement analysis revealed improvements in gait (lateral sway: p = 0.01; step length variability: p = 0.01) and in goal-directed leg placement (p = 0.03). Despite progressive cerebellar degeneration, children are able to improve motor performance by intensive coordination training. Directed training of whole-body controlled video games might present a highly motivational, cost-efficient, and home-based rehabilitation strategy to train dynamic balance and interaction with dynamic environments in a large variety of young-onset neurologic

Degenerative spinal disorders, including intervertebral disc disease and spondylosis, seldom occur in domestic cats. In contrast, a retrospective study of 13 lions (Panthera leo), 16 tigers (Panthera tigris), 4 leopards (Panthera pardis), 1 snow leopard (Panthera uncia), and 3 jaguars (Panthera onca) from the Knoxville Zoo that died or were euthanatized from 1976 to 1996 indicated that degenerative spinal disease is an important problem in large nondomestic felids. The medical record, radiographic data, and the necropsy report of each animal were examined for evidence of intervertebral disc disease or spondylosis. Eight (three lions, four tigers, and one leopard) animals were diagnosed with degenerative spinal disease. Clinical signs included progressively decreased activity, moderate to severe rear limb muscle atrophy, chronic intermittent rear limb paresis, and ataxia. The age at onset of clinical signs was 10-19 yr (median = 18 yr). Radiographic evaluation of the spinal column was useful in assessing the severity of spinal lesions, and results were correlated with necropsy findings. Lesions were frequently multifocal, included intervertebral disc mineralization or herniation with collapsed intervertebral disc spaces, and were most common in the lumbar area but also involved cervical and thoracic vertebrae. Marked spondylosis was present in the cats with intervertebral disc disease, presumably subsequent to vertebral instability. Six of the animals' spinal cords were examined histologically, and five had acute or chronic damage to the spinal cord secondary to disc protrusion. Spinal disease should be suspected in geriatric large felids with decreased appetite or activity. Radiographic evaluation of the spinal column is the most useful method to assess the type and severity of spinal lesions.

A retrospective study. To analyze the efficacy and safety of perioperative halo-gravity traction as an adjunct to posterior vertebral column resection (PVCR) in the treatment of patients with severe congenital scoliosis and coexisting asymptomatic intraspinal pathologies (diastematomyelia and/or tethered cord). Few reports to our knowledge review the use of perioperative halo-gravity traction and PVCR in this patient population. A total of 17 patients with a minimum 2-year follow-up who underwent PVCR using perioperative halo-gravity traction were analyzed. Patients were analyzed by age at date of examination (range, 11-23 y; mean, 14.4 y), sex (7 male, 10 female), major coronal curve magnitude (range, 108-149 degrees; average, 125 degrees), major sagittal curve magnitude (range, 72-118 degrees; average, 91 degrees). Complications related to halo traction and PVCR were reviewed. Radiographic outcomes demonstrated Cobb angle of major curve had an average correction of 28% after halo traction and it measured 53 degrees (range, 42-84 degrees) at the last follow-up, for a 58% correction. Maximal kyphosis improved to 58 degrees (range, 43-76 degrees) at ultimate follow-up. There were no permanent neurological deficits in this series. The study results suggested that surgical treatment for intraspinal abnormality may be unnecessary in asymptomatic patients with severe congenital scoliosis who are undergoing scoliosis corrective surgery. PVCR combined with perioperative traction is a safe and effective alternative for such patients.

Radiographic changes in the vertebrae are described that were observed following orthovoltage therapeutic irradiation in the treatment of Wilms's tumor, neuroblastoma, and medulloblastoma. Historical data and treatment faetors are tabulated for 17 cases. Observations on the incidence and severity of scoliosis and accompanying bony changes in l3 cases are presented. A review of the findings showed that the degree of scoliosis that developed was not related to the the fields of irradiation, whether they were unilateral or bilateral, and that the osseous changes in the vertebrae, pelvis, or ribs. The use of irradiation with surgery in the treatment of Wilms'smore » tumor is discussed. Radiological techniques are described to deliver maximum doses to the tumor and minimum doses to the surrounding normal structures in the treatment of these tumors. (C.H.)« less

By a combination of balance and isotope techniques, the following parameters of Ca metabolism were measured: pool size, rate of loss from pool, urinary excretion, fecal excretion, intake, endogenous fecal Ca, absorption, balance, bone formation, and bone resorption. The subjects were two normal women and five women with postmenopausal osteoporosis, aged 41 to 74 years, and four patients with scoliosis, aged 12 to 22 years. The latter were studied before, shortly after, and many months after immobilization in plaster casts. On the basis of observed relationships, it appeared that the negative Ca balance observed in the older women was duemore » to the low intensity of the various vectors of Ca metabolism, without clearcut distinction between the subjects with and without osteoporosis. Conversely, in the young patients with scoliosis, the negative balance incident to treatment by immobilization was associated with vectors of relatively high intensity whose relationships were altered temporarily.« less

The primary aim of this study was to (1) determine the clinical management approach of practicing chiropractors with regard to patients with adolescent idiopathic scoliosis and (2) measure the response rate of a telephone survey. A survey instrument was developed and pretested, and a case-specific clinical vignette was generated for a hypothetical typical 12-year-old girl with adolescent idiopathic scoliosis. The instrument addressed 3 domains: the specific management of idiopathic scoliosis, elements guiding the general selection of treatment recommendations, and demographics of respondents. The sample frame consisted of 62,000 US chiropractors, of whom 165 were randomly selected for the survey sample. Interviews were conducted by telephone through use of the tested survey instrument. The response rate was 69% (114/165). Of the 51 nonrespondents, 15 did not have a listed business telephone number and 24 were not in active practice. The response rate of those who met the inclusion criteria (practicing chiropractor with a listed telephone number) was 90% (114/126). The gender, chiropractic college, and years in practice of respondents in this survey were similar to those of respondents in 3 other national surveys. In general, the respondents would provide 6 months of "intensive" chiropractic therapy, then follow the patient for 4 years (near skeletal maturity). Eighty-two percent of respondents named diversified technique as their primary adjustive treatment, 87% would use exercise, and 30% would use electric muscle stimulation as an adjunct to manual therapy. Most surveyed chiropractors would use similar methods (frequency and length of treatment, manipulation technique, and exercise) in the treatment of patients with adolescent idiopathic scoliosis. A high response rate to a national survey can be achieved through use of telephone contact.

Photofluorography using a large-field image intensifier (Siemens Optilux 57) was applied to scoliosis radiography and compared with a full-size rare-earth screen/film technique. When scoliosis radiography (PA-projection) was performed on 25 adolescent patients, the photofluorographs were found to be of comparable diagnostic quality with full-size films. A close correspondence between the imaging techniques was found in the Cobb angle measurements as well as in the grading of rotation with the pedicle method. The use of photofluorography results in a radiation dose reduction of about one-half and considerable savings in direct imaging costs and archive space. In our opinion the method ismore » particularly well-suited for follow-up and screening evaluation of scoliosis, but in tall patients the image field size of 40 x 40 cm restricts its usefulness as initial examination.« less

Segmental spinal instrumentation with Luque wire fixation has been the standard treatment of neuromuscular scoliosis for >30 years. More recently, pedicle screw constructs have become the most widely utilized method of posterior spinal fixation; however, they are associated with complications such as implant malposition. We report the use of polyester bands and clamps utilized with pedicle screws in a hybrid fixation construct in the treatment of neuromuscular scoliosis. A retrospective review was conducted of 115 pediatric spinal deformity cases between 2008 and 2010 at a single center performed by a single surgeon. Intraoperative and postoperative complications were recorded. Radiographs were reviewed preoperatively and at the latest follow-up. A systematic review of the literature was conducted. Data from case series reporting outcomes of sublaminar wires and all-pedicle screw constructs in the treatment of neuromuscular scoliosis were compared with outcomes of the present study. Twenty-nine patients with neuromuscular scoliosis who underwent segmental spinal instrumentation with a hybrid construct including sublaminar bands and pedicle screws were included. There was an average follow-up of 29 months (range, 12 to 40 mo). The average postoperative correction of coronal balance was 69% (range, 24 to 71 degrees). Sagittal balance was corrected to within 2 cm of the C7 plumbline in 97% of patients. The loss of coronal and sagittal correction at latest follow-up was 0% and 2%, respectively. There were 2 intraoperative clamp failures of the 398 implants (0.5%). There were 2 major (6.9%) and 7 minor (24%) complications in 7 patients (24% overall). These results compared favorably to previous case series of sublaminar wire and all-pedicle screw fixation techniques. The polyester band technique is an excellent adjunct in the correction of spinal deformity in patients with neuromuscular scoliosis. Sublaminar bands utilized in a hybrid construct appear to be safe, can

Retrospective case series. This study aimed to validate the Sanders Skeletal Maturity Staging System and to assess its correlation to curve progression in idiopathic scoliosis. The Sanders Skeletal Maturity Staging System has been used to predict curve progression in idiopathic scoliosis. This study intended to validate that initial study with a larger sample size. We retrospectively reviewed 1100 consecutive patients with idiopathic scoliosis between 2005 and 2011. Girls aged 8 to 14 years (<2 yr postmenarche) and boys aged 10 to 16 years who had obtained at least 1 hand and spine radiograph on the same day for evaluation of skeletal age and scoliosis curve magnitude were followed to skeletal maturity (Risser stage 5 or fully capped Risser stage 4), curve progression to 50° or greater, or spinal fusion. Patients with nonidiopathic curves were excluded. There were 161 patients: 131 girls (12.3 ± 1.2 yr) and 30 boys (13.9 ± 1.1 yr). The distribution of patients within Sanders stage (SS) 1 through 7 was 7, 28, 41, 45, 7, 31, and 2 patients, respectively; modified Lenke curve types 1 to 6 were 26, 12, 63, 5, 38, and 17 patients, respectively. All patients in SS2 with initial Cobb angles of 25° or greater progressed, and patients in SS1 and SS3 with initial Cobb angles of 35° or greater progressed. Similarly, all patients with initial Cobb angles of 40° or greater progressed except those in SS7. Conversely, none of the patients with initial Cobb angles of 15° or less or those in SS5, SS6, and SS7 with initial Cobb angles of 30° or less progressed. Predictive progression of 67%, 50%, 43%, 27%, and 60% was observed for subgroups SS1/30°, SS2/20°, SS3/30°, SS4/30°, and SS6/35° respectively. This larger cohort shows a strong predictive correlation between SS and initial Cobb angle for probability of curve progression in idiopathic scoliosis. 3.

A cross section of Web sites accessible to the general public was surveyed. To evaluate the quality and accuracy of information on scoliosis that a patient might access on the Internet. The Internet is a rapidly expanding communications network with an estimated 765 million users worldwide by the year 2005. Medical information is one of the most common sources of inquires on the Web. More than 100 million Americans accessed the Internet for medical information in the year 2000. Undoubtedly, the use of the Internet for patient information needs will continue to expand as Internet access becomes more readily available. This expansion combined with the Internet's poorly regulated format can lead to problems in the quality of information available. Since the Internet operates on a global scale, implementing and enforcing standards have been difficult. The largely uncontrolled information can potentially negatively influence consumer health outcomes. To identify potential sites, five search engines were selected and the word "scoliosis" was entered into each search engine. A total of 50 Web sites were chosen for review. Each Web site was evaluated according to the type of Web site, quality content, and informational accuracy by three board-certified academic orthopedic surgeons, fellowship trained in spinal surgery, who each has been in practice for a minimum of 8 years. Each Web site was categorized as academic, commercial, physician, nonphysician health professional, and unidentified. In addition, each Web site was evaluated according to scoliosis-specific content using a point value system of 32 disease-specific key words pertinent to the care of scoliosis on an ordinal scale. A list of these words is given. Point values were given for the use of key words related to disease summary, classifications, treatment options, and complications. The accuracy of the individual Web site was evaluated by each spine surgeon using a scale of 1 to 4. A score of 1 represents that

Adolescent idiopathic scoliosis is a 3D spinal deformity in frontal, sagittal and axial planes, with high relevance in the pediatric population especially in adolescents and females between 10 years of age and the end of growth spurt and skeletal maturity. The radiographic manifestation is a curve greater than 10° measured by Cobb method associated with vertebral rotation. "Idiopathic" diagnosis has to be done after neuroanatomical anomalies of the posterior cerebral fosa and spinal canal have been ruled out. The physical finding of a thoracic or lumbar hump is the clinical manifestation of vertebral rotation seen in a forward bending test (Adam's Test). It is recommended that all curves with a magnitude greater than 20° have to be controlled and treated by a spinal surgeon being observation, bracing and surgery the different treatment options based on the extent, progression of deformity and basically the clinical condition of the patient.

Anterior release and fusion is sometimes required in pediatric patients with thoracic scoliosis. Typically, a formal anterior approach is performed through open thoracotomy or video-assisted thoracoscopic surgery. The authors recently developed a technique for anterior release and fusion in thoracic scoliosis referred to as "posterior convex release and interbody fusion" (PCRIF). This technique is performed via the posterior-only approach typically used for posterior instrumentation and fusion and thus avoids a formal anterior approach. In this article the authors describe the technique and its use in 9 patients-to prevent a crankshaft phenomenon in 3 patients and to optimize the correction in 6 patients with a severe thoracic curve showing poor reducibility. After Ponte osteotomies at the levels requiring anterior release and fusion, intervertebral discs are approached from the convex side of the scoliosis. The annulus on the convex side of the scoliosis is incised from the lateral border of the pedicle to the lateral annulus while visualizing and protecting the pleura and spinal cord. The annulus in contact with the pleura and the anterior longitudinal ligament are removed before completing the discectomies and preparing the endplates. The PCRIF was performed at 3 levels in 4 patients and at 4 levels in 5 patients. Mean correction of the main thoracic curve, blood loss, and length of stay were 74.9%, 1290 ml, and 7.6 days, respectively. No neurological deficit, implant failure, or pseudarthrosis was observed at the last follow-up. Two patients had pleural effusion postoperatively, with 1 of them requiring placement of a chest tube. One patient had pulmonary edema secondary to fluid overload, while another patient underwent reoperation for a deep wound infection 3 weeks after the initial surgery. The technique is primarily indicated in skeletally immature patients with open triradiate cartilage and/or severe scoliosis. It can be particularly useful if there is

The purpose was to describe posture, ability to change position, and association between posture and contractures, hip dislocation, scoliosis, and pain in young adults with cerebral palsy (CP). Cross-sectional data of 102 people (63 males, 39 females; age range 19-23 y, median 21 y) out of a total population with CP was analysed in relation to Gross Motor Function Classification System (GMFCS) levels I (n=38), II (n=21), III (n=13), IV (n=10), and V (n=20). The CP subtypes were unilateral spastic (n=26), bilateral spastic (n=45), ataxic (n=12), and dyskinetic CP (n=19). The Postural Ability Scale was used to assess posture. The relationship between posture and joint range of motion, hip dislocation, scoliosis, and pain was analysed using logistic regression and Spearman's correlation. At GMFCS levels I to II, head and trunk asymmetries were most common; at GMFCS levels III to V postural asymmetries varied with position. The odds ratios (OR) for severe postural asymmetries were significantly higher for those with scoliosis (OR=33 sitting), limited hip extension (OR=39 supine), or limited knee extension (OR=37 standing). Postural asymmetries correlated to hip dislocations: supine (r(s) =0.48), sitting (r(s) =0.40), standing (r(s) =0.41), and inability to change position: supine (r(s) =0.60), sitting (r(s) =0.73), and standing (r(s) =0.64). Postural asymmetries were associated with scoliosis, hip dislocations, hip and knee contractures, and inability to change position. © 2013 The Authors.

ptk7 mutant zebrafish models of congenital and idiopathic scoliosis implicate dysregulated Wnt signalling in disease

Scoliosis is a complex genetic disorder of the musculoskeletal system, characterized by three-dimensional rotation of the spine. Curvatures caused by malformed vertebrae (congenital scoliosis (CS)) are apparent at birth. Spinal curvatures with no underlying vertebral abnormality (idiopathic scoliosis (IS)) most commonly manifest during adolescence. The genetic and biological mechanisms responsible for IS remain poorly understood due largely to limited experimental models. Here we describe zygotic ptk7 (Zptk7) mutant zebrafish, deficient in a critical regulator of Wnt signalling, as the first genetically defined developmental model of IS. We identify a novel sequence variant within a single IS patient that disrupts PTK7 function, consistent with a role for dysregulated Wnt activity in disease pathogenesis. Furthermore, we demonstrate that embryonic loss-of-gene function in maternal-zygotic ptk7 mutants (MZptk7) leads to vertebral anomalies associated with CS. Our data suggest novel molecular origins of, and genetic links between, congenital and idiopathic forms of disease. PMID:25182715

Proprioceptive insoles are known to influence the functions of posture and gait by modulations of the sensory structures at the sole of the foot. Literature has shown that they could improve the position of the upper-body in patients with postural complaints of the musculoskeletal system. The aim of this study was to evaluate the influence of proprioceptive insoles on the spinal curvature in patients with slight idiopathic scoliosis. Eighteen patients were included in this prospective, single-centre, randomized study. All patients needed to have a relevant growth potential and suffered from a slight idiopathic scoliosis. Two groups were used, where group 1 performed physiotherapy twice a week, whereas group 2 was additionally supplied with proprioceptive insoles. Patients underwent three-dimensional rasterstereography for back-shape analysis. Furthermore, a conventional x-ray imaging of the spine was performed at the beginning and 1 year later to document the curvatures. There was no statistical difference in the Cobb angles, and in almost all parameters of the rasterstereography, there was no statistically significant change between and within both groups. According to the results of this study, there was no evidence of any statistical significant effect of proprioceptive insoles on spinal curvature in patients with slight idiopathic scoliosis.

The role of spinal concave–convex biases in the progression of idiopathic scoliosis

Inadequate understanding of risk factors involved in the progression of idiopathic scoliosis restrains initial treatment to observation until the deformity shows signs of significant aggravation. The purpose of this analysis is to explore whether the concave–convex biases associated with scoliosis (local degeneration of the intervertebral discs, nucleus migration, and local increase in trabecular bone-mineral density of vertebral bodies) may be identified as progressive risk factors. Finite element models of a 26° right thoracic scoliotic spine were constructed based on experimental and clinical observations that included growth dynamics governed by mechanical stimulus. Stress distribution over the vertebral growth plates, progression of Cobb angles, and vertebral wedging were explored in models with and without the biases of concave–convex properties. The inclusion of the bias of concave–convex properties within the model both augmented the asymmetrical loading of the vertebral growth plates by up to 37% and further amplified the progression of Cobb angles and vertebral wedging by as much as 5.9° and 0.8°, respectively. Concave–convex biases are factors that influence the progression of scoliotic curves. Quantifying these parameters in a patient with scoliosis may further provide a better clinical assessment of the risk of progression. PMID:19130096

To evaluate the radiographic results and complications of growth-friendly (GF) surgery in the treatment of early-onset scoliosis (EOS) associated with Goldenhar syndrome. Goldenhar syndrome has been associated with spinal deformity, which may be progressive. Efficacy and complication rate of GF treatment has not been reported for this population of patients with EOS. Patients with Goldenhar syndrome and EOS with two years' follow-up were identified from two international multicenter EOS databases. Scoliosis, kyphosis, spine height, and hemithoracic height/width were determined preimplant, immediately postoperative, and at the two-year follow-up. Severity of complications (SV) was recorded (Smith et al. JPO 2015). Ten patients met inclusion criteria and had a mean age of 4.6 ± 2.5 years at GF implantation (one spine and nine rib-based). Mean preoperative scoliosis was 64°, postimplant 52°, and at mean follow up of 2.4 ± 0.5 years was 50° (p = .09). Preoperative kyphosis was 36°, postimplant 38°, and final 42° (p = .08). Preoperative T1-S1 height was 23.5 cm, postimplant 23.6 cm, and final 27.3 cm (p = .06). Preoperative convex hemithoracic height was 10.4 cm, postimplant 7.9 cm, and final 12.8 cm (p < .05). Preoperative concave hemithoracic height was 8.4 cm, postimplant 8.8 cm, and final 9.9 cm (p = .30). Preoperative right hemithoracic width was 8.02 cm, postimplant 7.22 cm, and final 7.86 cm (p = .07). Preoperative left hemithoracic width was 7.18 cm, postimplant 7.86 cm, and final 8.60 cm (p = .43). Eight patients had ≥1 complication with SV I (n = 7), SV II (n = 2), and SV IIA (n = 7). These included infection (n = 4), migration (n = 3), pneumonia (n = 2), and instrumentation failure (n = 2). At minimum two-year follow-up, GF surgical intervention for the treatment of EOS associated with Goldenhar syndrome trended toward improvements in scoliosis and spine height, but had a significant improvement in convex hemithoracic height; however, the majority

Tethered spinal cord is frequently associated with scoliosis. It is still controversial whether a prophylactic untethering is necessary before correction procedure in scoliosis patients with tethered spinal cord. In this study we determined the clinical outcome of a one-stage posterior scoliosis correction without a prophylactic untethering for treating scoliosis with an asymptomatic tethered spinal cord. Seventeen (5 males and 12 females) scoliosis patients with tethered spinal cords were retrospectively reviewed. All patients underwent a one-stage posterior scoliosis correction without preventive untethering. Parameters of radiograph were used to assess correction result. The Scoliosis Research Society (SRS)-22 questionnaire was analyzed pre- and post-operatively to evaluate the clinical outcomes. The modified Japanese Orthopaedic Association (mJOA) score was used to assess the pre- and post-operative spinal cord function. The post-operative coronal Cobb angle was significantly decreased compared with preoperative. (23.8 ± 6.4° vs. 58.4 ± 12.6°, P < 0.01). The coronal Cobb angle was 22.4 ± 6.8° at the final follow-up evaluation. The apical vertebral translation (AVT) was also decreased significantly. (27.5 mm vs. 60.9 mm, P < 0.01). The SRS-22 total score was improved at the 1-year follow-up evaluation compared with the pre-operative SRS-22 total score (87 ± 4 vs. 70 ± 5, p < 0.05). The functional activities, pain, self-image, mental health, and surgery satisfactory scores at the final follow-up evaluation were all improved compared with the corresponding pre-operative scores, especially the self-image and mental health scores (p < 0.05). The spinal cord function was stable and there was no new neurological symptoms after scoliosis correction. No difference existed between the pre- and post-operative total mJOA score (26 ± 2 vs. 27 ± 2, p = 0.39), which including subjective symptom (p = 0.07), clinical symptom (p = 0

To describe the successful perioperative hemostatic management of a Jehovah's Witness patient with hemophilia B and anaphylactic inhibitors to factor IX, undergoing scoliosis surgery. A 14 (1/2)-yr-old boy with severe hemophilia B who had a history of anaphylactic inhibitors to factor IX was scheduled to undergo corrective scoliosis surgery. He was initially started on epoetin alfa and iron supplementation to maximize preoperative red cell mass. Additionally, he was placed on a desensitization protocol of recombinant coagulation factor IX (rFIX) and was then treated with activated recombinant coagulation factor VII (rFVIIa) during the postoperative period. Tranexamic acid was given concomitantly. The intraoperative blood loss was approximately 350 mL. The nadir hemoglobin concentration was 111 g.L(-1) on postoperative days one and two. On postoperative day 11, the patient was stable and discharged home with a hemoglobin of 138 g.L(-1). He did not require blood transfusion and no adverse events were observed. The use of rFIX, rFVIIa, erythropoetin, iron, and tranexamic acid before, during and after scoliosis surgery may be a viable and safe option for hemophilia patients with inhibitors, who refuse blood products.

Surgical management of severe rigid dystrophic neurofibromatosis (NF) scoliosis is technically demanding and produces varying results. In the current study, we reviewed 9 patients who were treated with combined anterior and posterior fusion using different types of instrumentation (i.e., pedicle screw, hybrid, and all-hook constructs) at our institute.Between September 2001 and July 2010 at our institute, 9 patients received anterior release/fusion and posterior fusion with different types of instrumentation, including a pedicle screw construct (n = 5), a hybrid construct (n = 3), and an all-hook construct (n = 1). We compared the pedicle screw group with the hybrid group to analyze differences in preoperative curve angle, immediate postoperative curve reduction, and latest follow-up curve angle.The mean follow-up period was 9.5 ± 2.9 years. The average age at surgery was 10.3 ± 3.9 years. The average preoperative scoliosis curve was 61.3 ± 13.8°, and the average preoperative kyphosis curve was 39.8 ± 19.7°. The average postoperative scoliosis and kyphosis curves were 29.7 ± 10.7° and 21.0 ± 13.5°, respectively. The most recent follow-up scoliosis and kyphosis curves were 43.4 ± 17.3° and 29.4 ± 18.9°, respectively. There was no significant difference in the correction angle (either coronal or sagittal), and there was no significant difference in the loss of sagittal correction between the pedicle screw construct group and the hybrid construct group. However, the patients who received pedicle screw constructs had significantly less loss of coronal correction (P < .05). Two patients with posterior instrumentation, one with an all-hook construct and the other with a hybrid construct, required surgical revision because of progression of deformity.It is difficult to intraoperatively correct dystrophic deformity and to maintain this correction after surgery.
