    Hallux valgus is a common foot problem whose cause and progression is multifactorial, complex, and poorly known. Hallux valgus shows a predilection toward women. It is a progressive disorder with no treatment known to slow or stop progression. Surgery is indicated in healthy individuals when nonoperative measures fail. Adverse effects of surgery include infection and recurrence. Many procedures have been described, including soft tissue and bony reconstruction of the first ray. The procedure that is indicated depends on the severity of the deformity. PMID:24559871

    The purpose of this article is to describe the MR findings of Hallux Valgus (HV) and Hallux Rigidus (HR). Twenty-four patients (11 with HV, 4 with HR, and 9 with both HV and HR) were studied at 1.5 Tesla MRI. Two separate observers evaluated the first ray blindly for the following signs: sesamoid position, sesamoid proliferation, hypertrophy of the median eminence, presence of a lateral facet, presence of an adventitial bursa, shape of the first metatarsal head, relative length of the first metatarsal, joint space loss, osteophytes (dorsalor lateral), marrow edema, geodes, subchondral sclerosis, intra-articular ossicle, and pes planus. The most common findings observed in HV were a hypertrophic medial eminence (95%), sesamoid proliferation (90%) and adventitial bursitis (70%). The most common findings observed in HR were osteophytes (77% and 69%), geodes, and marrow edema. We conclude that traditional routine radiograph signs of HV and HR may be applied to MR images.

    Recurrence of hallux valgus deformity can be a common complication after corrective surgery. The cause of recurrent hallux valgus is usually multifactorial, and includes patient-related factors such as preoperative anatomic predisposition, medical comorbidities, compliance with postcorrection instructions, and surgical factors such as choice of the appropriate procedure and technical competency. For a successful outcome, this cause must be ascertained preoperatively. Although the algorithm to determine which intervention should be used is not unlike that of primary hallux valgus surgery, operative correction of hallux valgus recurrence can be challenging. This article discusses these challenges, complications, causes, and techniques.

    The involvement of valgus hindfoot deformity in hallux valgus deformity was confirmed in a rheumatoid arthritis case with a destructive valgus hindfoot deformity. Correction of severe valgus, calcaneal lateral offset, and pronated foot deformity instantly normalized hallux valgus deformities postoperatively. Thus, careful hindfoot status evaluation is important when assessing forefoot deformity, including hallux valgus, in rheumatoid arthritis cases.

    Severe hallux valgus is a challenge to treat. If the basal osteotomy is a well known surgery for severe deformity, the chevron osteotomy is usually used in mild to moderate deformity. With a accurent fixation the chevron can also be used in severe deformity. Both techniques can be performed percutaneously and offer reliable techniques. PMID:27524702

  6. Basal cell carcinoma masquerading as a hallux valgus

    The incidence of primary skin cancers of the foot is exceedingly low; conversely, problems associated with a hallux valgus are common. A nonhealing ulcer overlying a hallux valgus managed conservatively with ointments and orthotic adjustments, and even with skin grafts, did not resolve over a period of 10 years. Ultimately, a shave biopsy revealed that the lesion was a basal cell carcinoma. Wide local excision and another skin graft resulted in tumour eradication and, finally, healing. Basal cell carcinoma associated with a hallux valgus has not been previously reported, and this reinforces the concept that malignant degeneration as the cause of any chronic ulceration should not be overlooked.

    2012-01-01

    Introduction The aetiology of hallux valgus is almost certainly multifactoral. The biomechanics of the first ray is a common factor to most. There is very little literature examining the anatomy of the proximal metatarsal articular surface and its relationship to hallux valgus deformity. Methods We examined 42 feet from 23 specimens in this anatomical dissection study. Results This analysis revealed three distinct articular subtypes. Type 1 had one single facet, type 2 had two distinct articular facets, and type 3 had three articular facets one of which was a lateral inferior facet elevated from the first. Type 1 joints occurred exclusively in the hallux valgus specimens, while type 3 joints occurred exclusively in normal specimens. Type 2 joints occurred in both hallux valgus and normal specimens. Another consistent finding in regards to the proximal articular surface of the first metatarsal was the lateral plantar prominence. This prominence possessed its own articular surface in type 3 joints and was significantly flatter in specimens with hallux valgus (p < 0.001) and the angle with the joint was significantly more obtuse (p < 0.001). Conclusions We believe the size and acute angle of this prominence gives structural mechanical impedance to movement at the tarsometatarsal joint and thus improves the stability. PMID:23610678

  8. Hallux valgus correction using a modified Hohmann technique.

    1995-04-01

    In 181 patients presenting with hallux valgus (247 toes), we performed a modified Hohmann procedure with Kirschner wire fixation of the osteotomy. Follow-up by a questionnaire was possible in 159 patients representing 217 operated toes (21 reoperations), and roentgenograms of bony healing were assessed in all these patients. The questionnaire was returned by 91% (145/159) of the patients. The average observation time was 52 months (25-97 months). The average correction of the hallux valgus angle was 10 degrees, ranging from 31.4 degrees before surgery to 21.4 degrees after surgery. Eighty-eight percent of the patients stated that they had an excellent or good/fair result, and 12% had pain or problems with footwear. We found a positive correlation among the correction of the valgus angle, the lateral displacement, shortening of the first metatarsal, and the overall result. No correlation was found among the plantar displacement, correction of the intermetatarsal angle and the result. The modified Hohmann procedure is, in our opinion, a safe and reliable procedure for treating hallux valgus deformity of the foot.

    Endoscopic distal soft-tissue procedure is one of the minimally invasive techniques for correction of the hallux valgus deformity. It employs the same principle as the open procedure. The intermetatarsal angle is corrected by screw and interosseous suture instead of first metatarsal osteotomy. The associated procedures of first metatarsal derotation, medial collateral ligament reconstruction, and arthroscopic Lapidus arthrodesis can tackle various problems faced during the endoscopic distal soft-tissue procedure.

    Very little is known about the relationship between proximal joint alignment and hallux valgus among young dancers. This study sought to determine the extent to which spinal and lower extremity alignments are involved in hallux valgus, and to identify predicting variables for its development in young dancers. A group of 1336 young female dancers aged 8-16 years, and 226 control participants of the same age cohort were screened for the presence of hallux valgus, body physique characteristics, joint range of motion, and anatomical anomalies. Hallux valgus was common in the 2 young female populations studied. Among the dancers, 40.0% had bilateral hallux valgus and 7.3% unilateral. Among the controls, 32.3% had bilateral and 1.8% unilateral hallux valgus (χ2=8.27, df=1, p=0.004). Following logistic regression analysis, age (OR=1.028, 95% CI=0.968-1.091), genu varum (OR=1.514; CI=1.139-2.013) and scoliosis (OR=2.089; CI=1.113-3.921) were found to be significant predicting factors for hallux valgus in the dancer group, whereas in the control group, the predicting factors were age (OR=0.911, 95% CI=0.801-1.036) and ankle plantar flexion range of motion (OR=0.972; CI=0.951-0.992). In conclusion, it was found that spinal deformity, lower extremity alignment, and joint range of motion are strongly related to hallux valgus. PMID:25144433

    The treatment of hallux valgus depends on multiple factors, including clinical examination, patient considerations, clinical findings, radiographic assessment, and surgeon preference. Appropriate procedure selection and proper technique will usually result in good-to-excellent outcomes. Complications following hallux valgus correction include recurrence, transfer metatarsalgia, avascular necrosis, hallux varus, and nonunion and malunion of metatarsal osteotomies. In order to decrease the risks of complication, a precise and meticulous physical examination should be conducted preoperatively. In addition, a surgeon should select appropriate osteotomies to correct complex hallux valgus deformities. As a general principle, the severity of deformity dictates treatment options. PMID:25129349

    [Purpose] Hallux valgus is one of the most common deformations of the human foot, and it causes great difficulties for the patients. The aim of this paper was to review available medical literature in search of evidence which would justify implementation of physiotherapy, based on its effectiveness for patients with hallux valgus. [Subjects and Methods] The following databases were searched for applicable papers: PubMed, Google Scholar, Clinical Key and UpToDate. Full-text articles from the last 15 years were subjected to a review, which ultimately selected seven papers about hallux valgus therapy published over the past 12 years. These studies were grouped according to their design and level of evidence and classified depending on whether they concerned physiotherapy as postoperative therapy or as the only treatment. [Results] The studies included in the present analysis used the following interventions for patients with hallux valgus: exercise, manual therapy, gait training, taping and orthosis. All the studies showed beneficial effects and the most frequently observed results were reductions in pain and improvements in function. [Conclusion] The evidence found in the reviewed materials clearly indicates that patients with hallux valgus should not only be subject to surgical procedures but also undergo physiotherapeutic treatment.

    Over a 10-year period, 46 feet with hallux valgus in 36 patients were treated with the McBride procedure. The median age was 35 years. At follow-up of 2 to 11 years after operation, a reduction in the hallux valgus angles, the intermetatarsal angles and the width of the forefeet was found. In patients older than 30 years there were significant reductions. In patients younger than 30 years, the reduction was not significant. The rate of problems with daily footwear was reduced from 36 of 46 feet to 13 of 38 feet. The authors noted few problems and a high rate of satisfied patients, despite the age. In 37 of 46 feet the overall result was found satisfactory by the patients. The authors find that McBride's operation can be used for hallux valgus, also in patients above 30 years, in spite of the generally accepted restriction to younger individuals.

    Osteotomy of the proximal metatarsal for the correction of moderate to severe hallux valgus deformity is commonly performed. The purpose of this study is to review the early results of a technique for the correction of hallux valgus, an opening wedge osteotomy of the proximal first metatarsal with opening wedge plate fixation. A review was performed of the results of 47 patients (49 feet) who underwent correction of hallux valgus with proximal metatarsal opening wedge osteotomy. All osteotomies were secured with plate fixation on the medial side. Evaluation consisted of preoperative and postoperative radiographic as well as clinical evaluations. Mean corrections of 7 degrees were achieved for the 1-2 intermetatarsal angles. Fourteen complications occurred, 6 of which involved mild hardware irritation and did not affect outcome. Four nonunions or delayed unions were identified. The authors find the opening wedge osteotomy of the proximal first metatarsal to be a technically straightforward procedure for correcting moderate to severe hallux valgus. The correction obtained is comparable to other described techniques. PMID:20400425

    The present report describes a new method of hallux abducto valgus deformity correction planning using the mechanical axis of the medial column (mechanical axis planning). This method of radiographic evaluation identifies an ideal position for the first metatarsal after correction and is useful regardless of the surgical procedure chosen. We retrospectively reviewed 200 radiographs to identify a "normal" value for the mechanical axis angle. We reviewed 100 radiographs of patients with hallux abducto valgus deformity (deformity group) and 100 radiographs of patients without hallux abducto valgus deformity (control group). The deformity group revealed an M1-M2 anatomic axis angle of 13.5° ± 2.83° and an M1-M2 mechanical axis angle of 11.58° ± 1°. The control group revealed an M1-M2 anatomic axis angle of 7.5° ± 1.76° and an M1-M2 mechanical axis angle of 11.19° ± 0.9°. The differences in the M1-M2 anatomic axis angle and M1-M2 mechanical axis angle were statistically significant between the control and deformity groups. We sought to provide a reliable method for planning hallux abducto valgus deformity correction by aligning the mechanical axis of the medial column and the mechanical axis of the first ray to the "normal" value of 11° to reduce the deformity.

    Although the efficacy of Akin proximal phalanx closing wedge osteotomy as a sole procedure for correction of hallux valgus deformity is questionable, when used in combination with other osseous corrective procedures, the procedure has been believed to be efficacious. However, a limited number of comparative studies have confirmed the value of this additional procedure. We identified patients who had undergone osseous hallux valgus correction with first metatarsal osteotomy or first tarsometatarsal joint arthrodesis with (n = 73) and without (n = 81) Akin osteotomy and evaluated their radiographic measurements at 3 points (preoperatively, within 3 months after surgery, and ≥6 months after surgery). We found that those people who had undergone the Akin procedure tended to have a larger hallux abduction angle and a more laterally deviated tibial sesamoid position preoperatively. Although the radiographic correction of the deformity was promising immediately after corrective surgery with the Akin osteotomy, maintenance of the correction was questionable in our cohort. The value of additional Akin osteotomy for correction of hallux valgus deformity is uncertain.

    2016-07-01

    Synopsis Hallux valgus is a progressive deformity of the first metatarsophalangeal joint that changes the anatomy and biomechanics of the foot. To date, surgery is the only treatment to correct this deformity, though the recurrence rate is as high as 15%. This clinical commentary provides instruction in a strengthening approach for treatment of hallux valgus deformity, by addressing the moment actions of 5 muscles identified as having the ability to counter the hallux valgus process. Unlike surgery, muscle strengthening does not correct the deformity, but, instead, reduces the pain and associated gait impairments that affect the mobility of people who live with the disorder. This review is organized in 4 parts. Part 1 defines the terms of foot motion and posture. Part 2 details the anatomy and biomechanics, and describes how the foot is changed with deformity. Part 3 details the muscles targeted for strengthening; the intrinsics being the abductor hallucis, adductor hallucis, and the flexor hallucis brevis; the extrinsics being the tibialis posterior and fibularis longus. Part 4 instructs the exercise and reviews the related literature. Instructions are given for the short-foot, the toe-spread-out, and the heel-raise exercises. The routine may be performed by almost anyone at home and may be adopted into physical therapist practice, with intent to strengthen the foot muscles as an adjunct to almost any protocol of care, but especially for the treatment of hallux valgus deformity.

    Radiographic angles are used to assess the severity of hallux valgus deformity, make preoperative plans, evaluate outcomes after surgery, and compare results between different methods. Traditionally, hallux valgus angle (HVA) has been measured by using a protractor and a marker pen with hardcopy radiographs. The main objective of this study is to compare HVA measurements performed using a smartphone and a traditional protractor. The secondary objective was to compare the time taken between those two methods. Six observers measured major HVA on 20 radiographs of hallux valgus deformity with both a standard protractor and an Apple iPhone. Four of the observers repeated the measurements at least a week after the original measurements. The mean absolute difference between pairs of protractor and smartphone measurements was 3.2°. The 95% confidence intervals for intra-observer variability were ±3.1° for the smartphone measurement and ±3.2° for the protractor method. The 95% confidence intervals for inter-observer variability were ±9.1° for the smartphone measurement and ±9.6° for the protractor measurement. We conclude that the smartphone is equivalent to the protractor for the accuracy of HVA measurement. But, the time taken in smartphone measurement was also reduced. PMID:25763918

    2014-01-01

    The objective of this study was to review the use of liposomal bupivacaine as a multimodal pain management adjunct following hallux valgus surgery. The study was a prospective review of a consecutive series of patients who underwent hallux valgus surgery and received liposomal bupivacaine. From postoperative day (POD) 1 to 4, pain scores, number of narcotic rescue pills used, and adverse events were recorded. Wound complications, narcotic refills, and unscheduled clinic and emergency room (ER) visits or hospital admissions for pain were also recorded. The average pain rating was <3.4 (±2.4) during POD 1 to 4. Four patients (28.6%) reported never experiencing pain (Numeric Rating Scale ≤1). Seventy-one percent used narcotic rescue pills on POD 1. There were no unscheduled office or ER visits or hospital admissions. One adverse event and one wound complication occurred. Liposomal bupivacaine may be a safe and useful adjunct in a multimodal pain regimen for patients undergoing hallux valgus surgery. More rigorous studies are needed to determine its efficacy, safety profile, and cost-effectiveness compared to placebo. PMID:25785470

    First ray function and hallux misalignment after isolated tibial sesamoidectomy have been topics of debate. Although sesamoidectomy has been proved to be effective in the relief of sesamoid pain, many foot and ankle surgeons remain hesitant to perform the procedure fearing a possible joint perturbation. To our knowledge, the present study is the first to evaluate both laboratory and clinical evidence of the association between isolated tibial sesamoidectomy and hallux abducto valgus deformity. The bench study consisted of 10 cadaveric limbs that were dissected and prepared for testing. Controlled valgus loads were applied before and after tibial sesamoidectomy. No significant difference was found in the joint position after sesamoidectomy in both the rectus (p = .36) and the dorsiflexed (p = .062) positions. The clinical evaluation consisted of a retrospective cohort of 5 females; all of whom underwent isolated tibial sesamoidectomy. The pre- and postoperative radiographs and self-reported pain scores (visual analog scale) were compared. None of the patients developed a postoperative hallux abducto valgus deformity. Neither the hallux abductus angle (p = .180) nor the intermetatarsal angle 1-2 (p = .180) changed significantly in the postoperative setting. The visual analog scale pain scores changed from a mean of 6.8 to 1, a significant difference (p = .042). Based on our observations and clinical experience, we believe that isolated tibial sesamoidectomy does not have a significant effect on the position of the first metatarsophalangeal joint when meticulous surgical technique is used to excise the sesamoid. Isolated tibial sesamoidectomy can provide substantial pain relief and appears to be a safe treatment for a variety of conditions affecting the tibial sesamoid.

    We sought to determine whether hallux valgus displaces the sesamoid bones laterally away from a stationary first metatarsal or whether the first metatarsal head is displaced medially from the stationary sesamoids, which remain in position relative to the rest of the forefoot. We reviewed weightbearing radiographs in the dorsal plantar view of 128 consecutive patients (149 feet) seen over 2 months in 2014. Of these, 82 feet (55%) had a hallux valgus angle of >15° (hallux valgus group) and 67 feet (45%) had an angle of no more than 15° (control group). We measured the absolute distances from the center of the lateral sesamoid and the first metatarsal head to the long axis of the second metatarsal. Next, the relative distances, defined as the ratio of these 2 absolute distances to the length of the second metatarsal, were calculated to adjust for foot size. Both the absolute and the relative distances from the center of the first metatarsal head to the second metatarsal differed significantly between the 2 groups and correlated positively with the hallux valgus angle and first intermetatarsal angle. However, neither the absolute nor the relative distance to the lateral sesamoid bone differed significantly between the groups, nor did they correlate with either of the 2 angles. Thus, despite medial shifting of the first metatarsal in hallux valgus, the lateral sesamoid retains its relationship to the second metatarsal in transverse plane. Its apparent lateral movement is a radiographic misinterpretation. Awareness of this misinterpretation should improve the success of corrective surgery.

    Percutaneous surgical techniques are suitable for the correction of the hallux valgus deformity. Satisfactory aesthetic and functional results obtained with the Reverdin- Isham osteotomy have been reported. The aim of this study was to describe dynamic plantar pressure redistribution after the correction of the deformity using this technique. A sample of 20 feet with mild or moderate hallux valgus was conformed and surgically treated using the Reverdin-Isham osteotomy. Clinical, radiological, surface and pressure assessments were performed pre and postoperatively. Postoperative mean (± SD) values of the American Orthopaedic Foot and Ankle Society (AOFAS) score, metatarsophalangeal, first intermetatarsal and proximal articular sect angles were 95.7 (3.3), 15.5° (5.4), 9.5° (1.5) y 5.3° (3.0), respectively. A significant decrease was observed in surface values of both lateral (P = 0.003) and medial (P = 0.001) masks of the forefoot. Mean pressure values of the lateral forefoot region denoted a significant increase (P < 0.001) while the medial forefoot region showed no change (P = 0.137). There is evidence that this particular surgical technique promotes a new plantar pressure pattern in the foot that might significantly favour the increase of the pressure observed under the lesser metatarsal heads and might not induce meaningful changes in the mean pressure registered under the first metatarsal head and hallux.

Mean pressure values of the lateral forefoot region denoted a significant increase (P < 0.001) while the medial forefoot region showed no change (P = 0.137). There is evidence that this particular surgical technique promotes a new plantar pressure pattern in the foot that might significantly favour the increase of the pressure observed under the lesser metatarsal heads and might not induce meaningful changes in the mean pressure registered under the first metatarsal head and hallux.

    The angle formed by the distal articular facet of the medial cuneiform has been evaluated and discussed by various investigators. However, no consistent method has been available to radiograph and measure this entity. The wide variability of the angle is not conducive to comparative analysis. Additionally, investigators have noted that the angles observed (obliquity) vary greatly because of changes in radiographic angle, foot position, rotation of the first ray, and declination of the first metatarsal. Recognizing that these variables exist, we propose a reproducible assessment using digital radiography and application of deformity of correction principles. Our results have indicated a mean distal medial cuneiform angle of 20.69° in normal feet, 23.51° with moderate hallux valgus, and 20.41° with severe hallux valgus deformity. The radiograph beam was kept at 15° from the coronal plane. An inverse relationship was found between the distal medial cuneiform angle and bunion severity. This was in contrast to our expected hypothesis. The overall angle of the first metatarsal-medial cuneiform did, however, correlate with the severity of the bunion deformity (p < .000). The obliquity values and intermetatarsal angles changed in direct relationship to the radiographic projection angle. This illustrates the importance of using standardized radiographic projection angles. We conclude that the 1-dimensional standard anteroposterior radiograph with assessment of the distal medial cuneiform angle cannot adequately demonstrate the pathologic features of hallux valgus. A better indicator appears to be the first metatarsal-medial cuneiform angle. This pathologic entity is a 3-dimensional one that incorporates the joint morphology of the first ray, triplane osseous positioning, and soft tissue imbalances. Perhaps, 3-dimensional computed tomography imaging will provide better insight into this entity.

    AIM: To define footwear outcomes following hallux valgus surgery, focusing on patient return to comfortable and heeled footwear and patterns of post-operative footwear selection. METHODS: Surgical intervention is indicated for symptomatic cases of hallux valgus unresponsive to conservative methods, with favourable reported outcomes. The return to various types of footwear post-operatively is reflective of the degree of correction achieved, and corresponds to patient satisfaction. Patients are expected to return to comfortable footwear post-operatively without significant residual symptoms. Many female patients will additionally attempt to return to high-heeled, narrow toe box shoes. However, minimal evidence exists to guide their expectations. Sixty-five female hallux valgus patients that had undergone primary surgery between 2011 and 2013 were retrospectively identified using our hospital surgical database. Patients were reviewed using a footwear-specific outcome questionnaire at a mean 18.5 mo follow-up. RESULTS: Eighty-six percent of patients were able to return to comfortable footwear post-operatively with minimal discomfort. Of those intending to resume wearing heeled footwear, 62% were able to do so, with 77% of these patients wearing these as or more frequently than pre-operatively. No significant difference was observed between pre- and post-operative heel size. Mean time to return to heeled footwear was 21.4 wk post-operation. Cosmetic outcomes were very high and did not adversely impact footwear selection. CONCLUSION: We report high rates of return to both comfortable and heeled shoes in female patients following primary hallux valgus surgery. We observed an “all-or-none phenomenon” where patients rejected a return to heeled footwear unless able to tolerate them at the same frequency and heel size as pre-operatively. A minority of patients were unable to return to comfortable footwear post-operatively, which had adverse ramifications on their quality

    The present study assessed the changes in the length of the first metatarsal bone after performing proximal chevron metatarsal osteotomy (PCMO) or distal Chevron metatarsal osteotomy (DCMO) for patients with hallux valgus deformity. A total of 60 patients with moderate-to-severe hallux valgus deformity from July 2009 to July 2011 were randomly divided into the PCMO and DCMO groups, with 30 patients in each group. The distal soft tissue procedure was performed in the same method for both groups. Measurements were performed preoperatively, postoperatively, and at the last follow-up visit at 6.1 ± 0.8 months. The postoperative length change with respect to the preoperative length was 0.7 ± 2.5 mm and -0.7 ± 5.1 mm for the PCMO and DCMO groups, respectively, with a slight lengthening of the first metatarsal bone in the PCMO group and a shortening in the DCMO group (p < .01). The follow-up length change with respect to the preoperative length was -2.1 ± 3.0 mm and -4.4 ± 2.2 mm for the PCMO and DCMO groups, respectively, demonstrating a clear shortening of the first metatarsal length at the last follow-up point in the DCMO group (p < .01).When DCMO and the distal soft tissue procedure were performed, significant shortening was found at 6 months of follow-up.

  9. Correlates of foot pain severity in adults with hallux valgus: a cross-sectional study

    2014-01-01

    Background Hallux valgus (HV) is highly prevalent and associated with progressive first metatarsophalangeal joint subluxation and osteoarthritis. The link between structural HV deformity and foot pain is unclear. This study investigated possible explanatory factors surrounding foot pain in HV, including radiographic HV angle and signs of joint degeneration. Methods Participants were 60 adults (53 female) with HV aged 20 to 75 years. Participant demographics and a range of radiographic, clinical and functional measures were considered potential correlates of foot pain. Self-reported foot pain (visual analogue scales and a dichotomous definition) was considered the dependent variable. Multivariate modelling was used to determine which characteristics and measures explained pain, with univariate analyses first used to screen potential variables. Results Approximately 20 to 30% of the variance in foot pain associated with HV could be explained by patient characteristics such as poorer general health status, lower educational attainment and increased occupational physical activity levels, in combination with some dynamic physical characteristics such as hallux plantarflexion weakness and reduced force-time integral under the second metatarsal during gait. Neither increasing lateral deviation of the hallux (HV angle) nor presence of first metatarsophalangeal joint osteoarthritis was associated with foot pain. Conclusions This study shows that passive structural factors, including HV angle, do not appear to be significant correlates of foot pain intensity in HV. Our data demonstrate the importance of considering patient characteristics such as general health and physical activity levels when assessing foot pain associated with HV. PMID:25028598

    To treat hallux valgus, minimally invasive osteotomy on 1st metatarsal neck,immobilization with "8-shape" bandagev was performed, and the effect was definited. The principles of osteotomy stability were analyzed from the osteotomy position, methods, direction and angle. The grinding drill was used to increase friction coefficient between the ends of osteotomy. Correct direction of osteotomy and suitable angle were the key point of stability. The immobilization with "8-shape" bandage complied with the principle of elastic fixation created the conditions for the slight movement of the osteotomy ends. Compared with internal fixation ,it was better on osteotomy healing,and the osteotomy ends were stable and healed with cartilage PMID:27149792

    Metatarsalgia is a recognised complication following iatrogenic shortening of the first metatarsal in the management of hallux valgus. The traditional surgical treatment is by shortening osteotomies of the lesser metatarsals. We describe the results of lengthening of iatrogenic first brachymetatarsia in 16 females. A Scarf-type osteotomy was used in the first four cases and a step-cut of equal thicknesses along the axis of the first metatarsal was performed in the others. The mean follow-up was 21 months (19 to 26). Relief of metatarsalgia was obtained in the six patients in whom 10 mm of lengthening had been achieved, compared to only 50% relief in those where less than 8 mm of lengthening had been gained. One-stage step-cut lengthening osteotomy of the first metatarsal may be preferable to shortening osteotomies of the lesser metatarsals in the treatment of metatarsalgia following surgical shortening of the first metatarsal.

    2016-01-01

    Purpose The aim of this study was to investigate new point-connecting measurements for the hallux valgus angle (HVA) and the first intermetatarsal angle (IMA), which can reflect the degree of subluxation of the first metatarsophalangeal joint (MTPJ). Also, this study attempted to compare the validity of midline measurements and the new point-connecting measurements for the determination of HVA and IMA values. Materials and Methods Sixty feet of hallux valgus patients who underwent surgery between 2007 and 2011 were classified in terms of the severity of HVA, congruency of the first MTPJ, and type of chevron metatarsal osteotomy. On weight-bearing dorsal-plantar radiographs, HVA and IMA values were measured and compared preoperatively and postoperatively using both the conventional and new methods. Results Compared with midline measurements, point-connecting measurements showed higher inter- and intra-observer reliability for preoperative HVA/IMA and similar or higher inter- and intra-observer reliability for postoperative HVA/IMA. Patients who underwent distal chevron metatarsal osteotomy (DCMO) had higher intraclass correlation coefficient for inter- and intra-observer reliability for pre- and post-operative HVA and IMA measured by the point-connecting method compared with the midline method. All differences in the preoperative HVAs and IMAs determined by both the midline method and point-connecting methods were significant between the deviated group and subluxated groups (p=0.001). Conclusion The point-connecting method for measuring HVA and IMA in the subluxated first MTPJ may better reflect the severity of a HV deformity with higher reliability than the midline method, and is more useful in patients with DCMO than in patients with proximal chevron metatarsal osteotomy.

    2010-01-01

    Background In spite of recent advances in post-operative pain relief, pain following orthopedic surgery remains an ongoing challenge for clinicians. We examined whether a well known and frequently prescribed homeopathic preparation could mitigate post-operative pain. Method We performed a randomized, double blind, placebo-controlled trial to evaluate the efficacy of the homeopathic preparation Traumeel S® in minimizing post-operative pain and analgesic consumption following surgical correction of hallux valgus. Eighty consecutive patients were randomized to receive either Traumeel tablets or an indistinguishable placebo, and took primary and rescue oral analgesics as needed. Maximum numerical pain scores at rest and consumption of oral analgesics were recorded on day of surgery and for 13 days following surgery. Results Traumeel was not found superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial, however a transient reduction in the daily maximum post-operative pain score favoring the Traumeel arm was observed on the day of surgery, a finding supported by a treatment-time interaction test (p = 0.04). Conclusions Traumeel was not superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial. A transient reduction in the daily maximum post-operative pain score on the day of surgery is of questionable clinical importance.

    [Purpose] To investigate the relationship between hallux valgus (HV) deformity and the position of rearfoot joints, and its effects on the quality of life, pain, and related functional status of women with bilateral hallux valgus (HV). [Subjects and Methods] The subjects were 27 right-dominant women. Demographic data, HV angle, weight-bearing and non-weight-bearing subtalar pronation (SP), and navicular height were recorded. Visual Analog Pain Scale, Foot Function Index (FFI), and the American Orthopaedic Foot and Ankle Society (AOFAS) first metatarsophalangeal- interphalangeal (MTP-IP) and AOFAS Mid foot (MF) Scales, and SF-36 were also used. [Results] HV angle, weight-bearing SP, and pain intensity of the left foot were higher. HV angle of left foot was correlated with all sub-scales of FFI, the pain parameter of AOFAS MTP-IP, and pain and total scores of AOFAS-MF Scale. HV angle of the left foot correlated with physical role, pain, and social function sub-domains of SF-36. Right HV angles were correlated with right foot pain and non-weight-bearing SP. [Conclusion] Increasing HV angle and pathomechanical changes in the rear foot are correlated, resulting in increasing pain and thus decreasing functional status as well as decreasing quality of life. Although all the participants were right-dominant, their left foot problems were more prominent. PMID:27134358

    Hallux Valgus (HV) is a highly prevalent forefoot deformity in older people associated with progressive subluxation and osteoarthritis of the first metatarsophalangeal (MTP) joint and it is believed to be associated with varying degrees of HV effect on the quality of life related to foot health. The aim of this study is to compare the impact of varying degrees of HV on foot health in a sample of older people. The sample consisted of 115 participants, mean age 76.7 ± 9.1, who attended an outpatient center where self-report data were recorded. The degree of HV deformity was determined in both feet using the Manchester Scale (MS) from stage 1 (mild) to 4 (very severe). Scores obtained on the Foot Health Status Questionnaire (FHSQ) were compared. This has 13 questions that assess 4 health domains of the feet, namely pain, function, general health and footwear. The stage 4 of HV shown lower scores for the footwear domain (11.23 ± 15.6); general foot health (27.62 ± 19.1); foot pain (44.65 ± 24.5); foot function (53.04 ± 27.2); vigour (42.19 ± 16.8); social capacity (44.46 ± 28.1); and general health (41.15 ± 25.5) compared with stage 1 of HV (P<0.05) and there were no differences of physical activity (62.81 ± 24.6). Often, quality of life decreases in the elderly population based in large part on their foot health. There is a progressive reduction in health in general and foot health with increasing severity of hallux valgus deformity which appears to be associated with the presence of greater degree of HV, regardless of gender.

    L'ostéotomie de Scarf constitue une technique chirurgicale bien décrite, grâce à ses résultats excellents, elle est considérée comme un traitement de choix de l'hallux valgus. Le but de ce travail est de décrire le profil épidémiologique et radio-clinique des hallux valgus, ainsi qu’évaluer les résultats radiologiques et fonctionnels des patients traités par la technique classique d'ostéotomie de Scarf. Nous avons mené une étude rétrospective, concernant 22 ostéotomies de Scarf chez 19 patients, opérés d'hallux valgus entre mai 2009 et janvier 2013. Le recul moyen était de 22,5 mois (3-42 mois). L'âge moyen des patients au moment de l'intervention était de 49 ans, avec des extrêmes de 19 et 75 ans. Tous les patients ont bénéficié d'une évaluation clinique et radiologique préopératoire et postopératoire ainsi qu'une analyse statistique. Au dernier recul, selon des critères subjectifs, nos résultats étaient très satisfaisants dans 42%, satisfaisants dans 52% et déçus dans 6%, et en fonction du score de l'AOFAS, les résultats étaient nettement améliorée avec un AOFAS préopératoire de 57% à 84% en postopératoire. Concernant les résultats radiologiques, la déformation métatarsophalangienne (angle M1P1) a été corrigée (43,63 °-12,8°) avec une p très significative (p <0,001). D'autre part une amélioration de l'Angle moyen M1M2, passer de 18,18° préopératoire à 12,95° au dernier recul, avec une correction significative (p <0,001). Le valgus épiphysaire de premier métatarsien (AADM) a été statistiquement amélioré (p <0,001), passer de 24,45° à 7,91°. Concernant les complications nous avons noté un cas de sepsis précoce superficiel géré par une antibiothérapie adaptée, deux cas de névrome et un cas d'ostéonécrose. Par contre on n'a pas noté aucune fracture per opératoire du premier métatarsien. Nous concluons que l'ostéotomie de Scarf est une technique reproductible fiable, en pleine

    Objective To determine whether hallux valgus (HV) was associated with potential risk factors including foot pain in a large, bi-racial cohort of older men and women. Methods We conducted a cross-sectional analysis of cohort members of the Johnston County Osteoarthritis Project of whom 1,502 had complete clinical and demographic data available (mean age 68 years, mean body mass index [BMI] 31.3 kg/m2, 68% women, 30% African American). The presence of HV was assessed visually using a validated examination. Multivariate logistic regression models with generalized estimating equations for the total sample and for each sex and race subgroup were used to examine the effect of age, BMI, foot pain, pes planus, and knee or hip radiographic osteoarthritis (OA) on HV. Results HV was present in 64% of the total sample (African American men=69%, African American women=70%, Caucasian men=54%, Caucasian women=65%). The association between HV and foot pain was elevated but not statistically significant (adjusted odds ratio [aOR] 1.21, 95% confidence interval 0.99, 1.47). Women, African American, older individuals, and those with pes planus or knee/hip OA had significantly higher odds of HV (aORs 1.17–1.48). Participants with higher BMI had lower odds of HV compared to those with normal BMI (aORs 0.54–0.72). Overall, patterns of associations were similar across subgroups. Conclusion HV was associated with female sex, African American race, older age, pes planus, and knee/hip OA and inversely associated with higher BMI. Early prevention and intervention approaches may be needed in high-risk groups; longitudinal studies would inform these approaches. PMID:25418024

    Objective: To evaluate the correction of the intermetatarsal angle after arthrodesis of the metatarsophalangeal joint of the hallux. We believe that varus deformity of the first metatarsal can be corrected after arthrodesis of the first metatarsophalangeal joint, without the need for proximal osteotomy. Methods: Forty-three feet of patients who had undergone arthrodesis of the first metatarsophalangeal joint between May 1997 and October 2009 were retrospectively analyzed by means of radiographs. The mean length of follow-up was 58 months. Measurements on the metatarsophalangeal angle, intermetatarsal angle and sesamoid dislocation were made using radiographs made before, immediately after and later on after the operation. Results: The mean metatarsophalangeal angle was 37.6 degrees preoperatively, 12.8 degrees immediately after the operation and 16.4 degrees later on after the operation. The mean intermetatarsal angle was 16 degrees preoperatively, 10 degrees immediately after the operation and 10.2 degrees later on after the operation. Regarding sesamoid dislocation, preoperative radiographs showed most feet to be classified as G3; immediately after the operation, most were classified as G2; and later on after the operation, most were G1. Conclusion: The intermetatarsal angle and sesamoid dislocation improved with arthrodesis of the first metatarsophalangeal joint, without the need for osteotomy at the base of the first metatarsal.

    Objective Hallux valgus (HV) affects ~36% of Caucasian adults. Although considered highly heritable, the underlying genetic determinants are unclear. We conducted the first genome-wide association study (GWAS) aimed to identify genetic variants associated with HV. Methods HV was assessed in 3 Caucasian cohorts (n=2,263, n=915, and n=1,231 participants, respectively). In each cohort, a GWAS was conducted using 2.5M imputed single nucleotide polymorphisms (SNPs). Mixed-effect regression with the additive genetic model adjusted for age, sex, weight and within-family correlations was used for both sex-specific and combined analyses. To combine GWAS results across cohorts, fixed-effect inverse-variance meta-analyses were used. Following meta-analyses, top-associated findings were also examined in an African American cohort (n=327). Results The proportion of HV variance explained by genome-wide genotyped SNPs was 50% in men and 48% in women. A higher proportion of genetic determinants of HV was sex-specific. The most significantly associated SNP in men was rs9675316 located on chr17q23-a24 near the AXIN2 gene (p=5.46×10−7); the most significantly associated SNP in women was rs7996797 located on chr13q14.1-q14.2 near the ESD gene (p=7.21×10−7). Genome-wide significant SNP-by-sex interaction was found for SNP rs1563374 located on chr11p15.1 near the MRGPRX3 gene (interaction p-value =4.1×10−9). The association signals diminished when combining men and women. Conclusion Findings suggest that the potential pathophysiological mechanisms of HV are complex and strongly underlined by sex-specific interactions. The identified genetic variants imply contribution of biological pathways observed in osteoarthritis as well as new pathways, influencing skeletal development and inflammation. PMID:26337638

    [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.

    [Purpose] Hallux valgus is one of the most common deformations of the human foot, and it causes great difficulties for the patients. The aim of this paper was to review available medical literature in search of evidence which would justify implementation of physiotherapy, based on its effectiveness for patients with hallux valgus. [Subjects and Methods] The following databases were searched for applicable papers: PubMed, Google Scholar, Clinical Key and UpToDate. Full-text articles from the last 15 years were subjected to a review, which ultimately selected seven papers about hallux valgus therapy published over the past 12 years. These studies were grouped according to their design and level of evidence and classified depending on whether they concerned physiotherapy as postoperative therapy or as the only treatment. [Results] The studies included in the present analysis used the following interventions for patients with hallux valgus: exercise, manual therapy, gait training, taping and orthosis. All the studies showed beneficial effects and the most frequently observed results were reductions in pain and improvements in function. [Conclusion] The evidence found in the reviewed materials clearly indicates that patients with hallux valgus should not only be subject to surgical procedures but also undergo physiotherapeutic treatment.

    Hallux deformities other than hallux valgus, especially those in the sagittal plane, have not yet been elucidated in the feet of patients with rheumatoid arthritis. The objectives of the present study were to classify rheumatoid arthritis hallux deformity in both the horizontal and the sagittal planes and investigate its relationship with flatfoot. Using a cross-sectional study design, we assessed patients with rheumatoid arthritis (527 feet in 274 patients) using radiographs and classified the deformity patterns of the great toes using cluster analysis. Of the 274 patients, the range of motion in the metatarsophalangeal joint was clinically investigated in 44 (16.1%) patients. The great toes could be divided into 5 clusters according to the characteristic configuration as follows: cluster I (normal type), cluster II (hallux valgus type), cluster III (boutonniere type), cluster IV (boutonniere with hallux valgus type), and cluster V (swan-neck type). Radiographic measurements revealed the characteristic deformities of each cluster, including splayed foot for cluster II; flat foot, metatarsal primus elevatus, and plantar displacement of the proximal phalanx for cluster III; and a mixture of these characteristics for cluster IV. Plantar displacement of the proximal phalanx, which was a specific characteristic of the boutonniere deformity, correlated significantly with the decreased dorsiflexion in the metatarsophalangeal joint. Our classification method revealed the relationship of hallux deformity in the sagittal plane to flatfoot and also demonstrated the usefulness of measuring basal phalanx displacement in predicting the range of motion of the metatarsophalangeal joint.

    Hallux rigidus is a degenerative condition leading to arthritis of the first metatarsophalangeal joint. Cheilectomy is a surgical procedure that is used in the treatment of hallux rigidus. It removes dorsal and dorsomedial or dorsolateral osteophytes, primarily relieving the impingement at the first metatarsophalangeal joint, which causes patients pain. The minimally invasive technique has proven to be an excellent technique to remove bony spurs to relieve symptoms with minimal surgical complications and fast recovery time. PMID:27524700

    Introduction Supracondylar femoral osteotomy is the time tested method, used for correcting the angular (varus & valgus) deformities at the knee. Traditionally, Coventry type of femoral osteotomy is performed. Here, a medial or lateral based wedge of bone is removed or an open wedge osteotomy is made & subsequently the space is filled with the bone graft to achieve the desired correction. This osteotomy is subsequently stabilized with Kirschner wires or plate & screws. Later the limb is externally supported in brace or plaster cast till osteotomy unites. Here we present a case series of 10 cases, where we have analyzed the efficacy of Aglietti procedure for achieving normal limb alignment with good patient satisfaction and subsequent knee function as a method of femoral supracondylar osteotomy for correcting the valgus deformity at the knee. Short series results are also encouraging with regard to the operating time, per-operative blood loss, postoperative stability of osteotomy, early starting of postoperative rehabilitation due to good stability at osteotomy & subsequent functional outcome in relation to final range of motion (ROM) – flexion after 6 months of surgery. Case series presentation Ten valgus adolescent knees were operated in 7 patients by the Aglietti procedure for correcting the angular deformity at the knee. The results were analyzed taking into consideration the desired correction to achieve normal limb alignment, operating time, blood loss during surgery estimated by the number of surgical mops used, stability of the osteotomy in the postoperative period & ultimate range of motion (ROM) obtained at the end of 6 months after the surgery. Results The age of the patients taken up in the study were in the range of 12–16 years. Females predominated (n = 5) against 2 males. The time taken for the procedure ranged from 40 to 50 min. The size of the surgical mops used was 15 × 20 cm. 1–2 surgical mops used per patient. The range of flexion

  9. Unilobed Rotational Flap for Plantar Hallux Interphalangeal Joint Ulceration Complicated by Osteomyelitis.

    Diabetes-related neuropathic ulcers located at the plantar aspect of the hallux interphalangeal joint are often chronic or recurrent and frequently become complicated by osteomyelitis. Once infected, treatment will typically involve hallux amputation. Although intended as a definitive procedure, amputation of the first toe is not desirable from a cosmetic or functional standpoint and often leads to transfer ulcers at adjacent locations of the foot. Reconstructive wound surgery, combined with limited bone resection, is possible if the infection is caught early before the local tissue and bone have become necrotic. In addition to neuropathy, biomechanical issues, including ankle equinus, hallux limitus, hallux extensus, and hallux valgus, predispose patients with diabetes mellitus to developing plantar hallux ulcers. We commonly employ a proximal based unilobed plantar rotational flap combined with hallux interphalangeal joint arthroplasty as an alternative to hallux amputation. We present a typical case with long-term follow-up to highlight our flap protocol, including patient selection criteria, flap design, surgical technique, bone resection and biopsy pearls, staging timeline, and a typical postoperative course. Periodic follow-up during the next 72 months for unrelated conditions allowed long-term monitoring with no recurrence of osteomyelitis or subsequent amputation. The foot remained ulcer free 6 years later. The benefits of this surgical approach include complete excision of the ulcer, adequate exposure for bone resection, early bone biopsy before the spread of infection or necrosis of local tissue, flap coverage with viable soft tissue, and partial offloading of mechanical pressure at the plantar interphalangeal joint.

    Diabetic foot ulceration of the plantar hallux is a challenging condition and can require partial hallux amputation when complicated by infection. Lower extremity biomechanics play an important role in the development of hallux ulcers, and hallux rigidus (HR) could influence the outcomes after partial hallux amputation. We hypothesized that radiographic evidence of HR in patients with diabetes would be associated with greater ulcer recurrence and reamputation rates after partial hallux amputation. We performed a retrospective review of all patients with diabetes who had undergone a partial hallux amputation from January 2005 to December 2012. The subjects were divided into 2 cohorts according to the presence or absence of HR identified on preoperative radiographs. Baseline characteristics and outcomes were compared using a 2-sample Student's t test for continuous variables, and categorical variables were compared using the chi-square test for homogeneity and Fisher's exact test. A total of 52 patients were included, with 16 (31%) positive for radiographic evidence of HR at partial hallux amputation. Differences in the patient demographics and comorbidities were not significant between 2 cohorts with and without HR or reamputation. Reamputation was required in 5 subjects (31%) with HR and 2 (6%) without HR (p = .023). The average follow-up duration was 126 ± 89 weeks. Our results have demonstrated that the reamputation rate after partial hallux amputation is significantly greater in patients with than in those without radiographic evidence of HR. Surgeons should evaluate patients for HR when planning partial hallux amputation and use adjuvant methods of offloading when HR is evident to prevent recurrent ulceration and reamputation.

    Background The purpose of this study was to report outcomes of congenital hallux varus deformity after surgical treatment. Methods We evaluated ten feet of eight patients with a congenital hallux varus deformity, including four feet combined with a longitudinal epiphyseal bracket (LEB). There were seven male patients and one female patient with a mean age of 33 months (range, 7 to 103 months) at the time of surgery. Two patients were bilaterally involved. The mean duration of follow-up was 5.9 years (range, 2.3 to 13.8 years). Clinical outcomes were assessed according to the criteria of Phelps and Grogan. Surgical procedures included the Farmer procedure, the McElvenny procedure or an osteotomy at the first metatarsal or proximal phalanx. Results The clinical results were excellent in two feet, good in six and poor in two feet. The LEB was associated with hallux varus in four feet and were treated by osteotomy alone or in conjunction with soft tissue procedure. Conclusions Congenital hallux varus was successfully corrected by surgery with overall favorable outcome. Preoperatively, a LEB should be considered as a possible cause of the deformity in order to prevent recurrent or residual varus after surgery. PMID:24900905

    2011-07-01

    Failure of the enlarged and deformed anterolateral portion of the femoral head to roll into the acetabulum during abduction alters hip joint mechanics. The resultant hinge abduction is associated with pain, and the patient often has restricted movement. A valgus osteotomy removes the deformed portion of the femoral head away from the weight-bearing area and ensures there is pain-free congruent range of movement around the weight-bearing position. The concomitant improvement in lever arm function and leg length results in a better gait pattern. In immature patients, abolition of hinge abduction allows the lateral acetabular ossification center to grow more normally. PMID:21742146

    Patients with chronic diabetes can develop plantar hallux ulcerations secondary to neuropathy, increased pressure, and deformity. The present retrospective study evaluated the efficacy of hallux interphalangeal joint (HIPJ) arthroplasty to address recalcitrant ulceration. Two groups of patients with diabetes were compared: a surgical group of 13 patients and a nonsurgical standard therapy group of 13 patients. The patients in the surgical group underwent HIPJ arthroplasty. All the patients in the standard therapy group received local wound care and offloading. The mean duration of follow-up was 19.5 (range 1.2 to 47.9) months, and the mean age was 55 ± 13.0 years. Statistical significance was found in the surgical group for faster time to healing (3.5 weeks [2.5, 4.25] vs 9 weeks [2, 17.29], p = .033) and lower incidence of ulcer recurrence (8% ± 7.69 vs 54% ± 53.85, p = .031). There were also fewer amputations in the surgical group (0% ± 0 vs 38% ± 38.6, p = .063). To our knowledge, only 1 other published study has evaluated HIPJ arthroplasty as a treatment of recalcitrant hallux ulceration. The present study adds comparison data from a nonoperative standard therapy group and found that HIPJ arthroplasty is an effective curative treatment option to address chronic plantar hallux ulcerations in diabetic patients with neuropathy.

    Hallux rigidus is the most commonly occurring arthritic condition of the foot and is marked by pain, limited motion in the sagittal plane of the first metatarsophalangeal joint and varying degrees of functional impairment. In conjunction with clinical findings, radiographic grading helps guide therapeutic choices. Nonsurgical management with anti-inflammatory medications, corticosteroid injections, or shoewear and activity modifications can be successful in appropriately selected patients. Patients with more severe disease or refractory to conservative management may benefit from surgical intervention. Operative options range from joint-preserving procedures (eg, cheilectomy with or without associated osteotomies) to joint-altering procedures (eg, arthroplasty or arthrodesis).

    Total condylar knee arthroplasty was performed on 64 knees with fixed valgus or valgus/flexion deformities. The technique for release of tight lateral and posterior structures is important to balance the ligament. Clinical results were rated good and excellent in 95% of the knees. Four patients with excessive flexion deformities required 6 weeks of cast bracing in the immediate postoperative period for instabilities caused by an imbalance in the spacing in flexion and extension. In no joint in the entire series did stability deteriorate with time. There were no patellar complications or nerve palsies noted. Radiographic evaluation revealed well-fixed components in 92% of the arthroplasties. None has required revision for mechanical loosening to date. With proper technique the total condylar prosthesis can be employed in knees with valgus or valgus/flexion deformities to give predictably good results. The total condylar III prosthesis may be required in severe combined deformities for added stability. PMID:6546120

    The purpose of this study was to determine the biomechanical and anthropometric factors contributing to elbow valgus torque during pitching. Video data of 14 youth pitchers throwing fastballs were used to calculate shoulder and elbow kinematics and kinetics. Peak elbow valgus torque averaged 18 Nm and occurred just before maximal shoulder external rotation. The magnitude of valgus torque was most closely correlated with the thrower's weight. When subject weight and height were controlled for, maximum shoulder abduction torque and maximum shoulder internal rotation torque were most strongly associated with elbow valgus torque, accounting for 85% of its variance (P <.001). When only kinematic variables were considered, maximum shoulder external rotation accounted for 33% of the variance in valgus torque. Given that the biomechanical variables correlated with peak valgus torque are not easily modifiable, limiting the number of innings pitched is likely the best way to reduce elbow injury in youth pitchers.

    Study Design Nonexperimental methodological study. Objectives To determine the interrater and intrarater reliability and validity of using observational risk screening guidelines to evaluate dynamic knee valgus. Background A deficiency in the neuromuscular control of the hip has been identified as a key risk factor for non-contact anterior cruciate ligament (ACL) injury in post pubescent females. This deficiency can manifest itself as a valgus knee alignment during tasks involving hip and knee flexion. There are currently no scientifically tested methods to screen for dynamic knee valgus in the clinic or on the field. Methods Three physiotherapists used observational risk screening guidelines to rate 40 adolescent female soccer players according to their risk of ACL injury. The rating was based on the amount of dynamic knee valgus observed on a drop jump landing. Ratings were evaluated for intrarater and interrater agreement using kappa coefficients. Sensitivity and specificity of ratings were evaluated by comparing observational ratings with measurements obtained using 3-dimensional (3D) motion analysis. Results Kappa coefficients for intrarater and interrater agreement ranged from 0.75 to 0.85, indicating that ratings were reasonably consistent over time and between physiotherapists. Sensitivity values were inadequate, ranging from 67–87%. This indicated that raters failed to detect up to a third of “truly high risk” individuals. Specificity values ranged from 60–72% which was considered adequate for the purposes of the screen. Conclusion Observational risk screening is a practical and cost-effective method of screening for ACL injury risk. Rater agreement and specificity were acceptable for this method but sensitivity was not. To detect a greater proportion of individuals at risk of ACL injury, coaches and clinicians should ensure that they include additional tests for other high risk characteristics in their screening protocols.

    Impacted valgus fractures of the proximal humerus are considered to be a special type fracture, since impaction of the humeral head on the metaphysis with maintenance of the posteromedial periosteum improves the prognosis regarding occurrences of avascular necrosis. This characteristic can also facilitate the reduction maneuver and increase the consolidation rate of these fractures, even in more complex cases. The studies included were obtained by searching the Bireme, Medline, PubMed, Cochrane Library and Google Scholar databases for those published between 1991 and 2013. The objective of this study was to identify the most common definitions, classifications and treatment methods used for these fractures in the orthopedic medical literature.

    The majority of orthopaedic surgeons even currently agree that primary total arthroplasty in valgus knees with a deformity of more than ten degrees may prove challenging. The unique sets of bone and soft tissue abnormalities that must be addressed at the time of the operation make accurate axis restoration, component orientation and joint stability attainment a difficult task. Understanding the specific pathologic anatomic changes associated with the valgus knee is a prerequisite so as to select the proper surgical method, to optimize component position and restore soft-tissue balance. The purpose of this article is to review the valgus knee anatomical variations, to assess the best pre-operative planning and to evaluate how to choose the grade of constraint of the implant. It will also be underlying the up-to-date main approaches and surgical techniques be proposed in the English literature both for bone cuts and soft tissue management of valgus knees. PMID:26191494

    End-stage arthritis of the first metatarsophalangeal joint (MTPJ) typically results in anexophytic process with marked limitation of motion. Pain may occur from the degenerative process itself and/or the bone spur formation that may become directly inflamed from shoe gear. The best surgical treatment for end-stage arthrosis of the big toe joint continues to be a controversial topic despite hallux rigidus being recognized clinically for more than 100 years. Although joint-sparing procedures are considered, arthrodesis is recommended, as this procedure is definitive and produces predictable results. PMID:22727376

    The purpose of this study was to determine if metatarsal protrusion or the length of the first and second rays were associated with the incidence of hallux rigidus. For this retrospective study, anteroposterior radiographs from 51 patients diagnosed with hallux rigidus and 51 patients without evidence of hallux rigidus were selected for review as a control group. Radiographs were randomly assigned to one of two raters who determined the metatarsal protrusion distance, first metatarsal length, second metatarsal length, length of the proximal phalanx of the hallux, length of the proximal phalanx of the second toe, and overall hallux length. A statistical comparison of these radiographic measurements showed only first metatarsal length to significantly differ (P = .05) between the two groups (65.4 +/- 5.3 mm and 67.7 +/- 5.9 mm for the hallux rigidus and control groups, respectively). The findings of this study suggest the need to revisit the role that metatarsal protrusion distance and first metatarsal length play in the etiology of hallux rigidus. In addition the need to surgically correct a long first metatarsal should be further evaluated.

    Context: Two-dimensional (or medial knee displacement [MKD]) and 3-dimensional (3D) knee valgus are theorized to contribute to anterior cruciate ligament injuries. However, whether these displacements can be improved in the double-legged squat (DLS) after an exercise intervention is unclear. Objective: To determine if MKD and 3D knee valgus are improved in a DLS after an exercise intervention. Design:  Randomized controlled clinical trial. Setting: Research laboratory. Patients or Other Participants: A total of 32 participants were enrolled in this study and were randomly assigned to the control (n = 16) or intervention (n = 16) group. During a DLS, all participants demonstrated knee valgus that was corrected with a heel lift. Intervention(s):  The intervention group completed 10 sessions of directed exercise that focused on hip and ankle strength and flexibility over a 2- to 3-week period. Main Outcome Measure(s): We assessed MKD and 3D knee valgus during the DLS using an electromagnetic tracking system. Hip strength and ankle-dorsiflexion range of motion were measured. Change scores were calculated for MKD and 3D valgus at 0%, 10%, 20%, 30%, 40%, and 50% phases, and group (2 levels)-by phase (6 levels) repeated-measures analyses of variance were conducted. Independent t tests were used to compare change scores in other variables (α < .05). Results: The MKD decreased from 20% to 50% of the DLS (P = .02) and 3D knee valgus improved from 30% to 50% of the squat phase (P = .001). Ankle-dorsiflexion range of motion (knee extended) increased in the intervention group (P = .009). No other significant findings were observed (P > .05). Conclusions:  The intervention reduced MKD and 3D knee valgus during a DLS. The intervention also increased ankle range of motion. Our inclusion criteria might have limited our ability to observe changes in hip strength. PMID:23724771

    In this investigation, we determined the patterns of valgus laxity and acquired valgus laxity of the ulnar collateral ligament in the elbows of collegiate athletes involved in overhead and nonoverhead sports. Acquired valgus laxity of the elbow is defined as the differential amount of stress valgus opening between the dominant and nondominant elbows. Forty-eight asymptomatic male athletes involved in sports that require overhead arm movements (baseball, tennis, and swimming) and 88 asymptomatic male athletes involved in nonoverhead sports (track, lacrosse, fencing, and wrestling) underwent fluoroscan examination of both their elbows with (13 daN) and without (0 N) valgus stress. There were no statistically significant differences in the amount of valgus stress opening or in acquired valgus laxity between the two groups. In fact, 25% (34 of 136) of the athletes showed an acquired valgus laxity of more than 0.5 mm, and 51.5% (70 of 136) had an acquired valgus laxity that was actually negative. There was also no correlation between the number of years played and acquired valgus laxity. Our results show that acquired valgus laxity does not exist in asymptomatic athletes involved in overhead sports, and there is no threshold value of measurement indicative of acquired valgus laxity.

    Giant cell reparative granuloma (GCRG) is a rare, benign intra osseous lytic lesion occurring especially in gnathis bone but also seen in feet and hands. It has similar clinical and radiological presentations than giant cell tumor, chondroblastoma, aneurysmal bone cyst, and hyperparathyroidism brown tumors but with specific histological findings We report a case of a GCRG of hallux phalanx in 18 years old patient appearing many years after enchondroma curettage and grafting. Radiographs showed a multiloculated osteolytic lesions involving whole phalanx with cortical thinning and without fluid-fluid levels in CT view. Expected to be an enchondroma recurrence, second biopsy confirmed diagnosis of GCRG with specific histological findings. Although if aetiopathogeny remains unknown, GCRG is reported to be a local non neoplasic reaction to an intraosseous hemorrhage. Our exceptional case claims that this tumor can appear in reaction to cellular disturbance primary or secondary. PMID:26985281

    Nonunion neck of femur can be a difficult problem to treat, particularly in the young, and is associated with high complication rates of avascular necrosis due to the precarious blood supply and poor biomechanics. The various treatment options that have been described can be broadly divided according to the aim of improving either biology or biomechanics. Surgeries aimed at improving the biology, such as vascularized fibula grafting, have good success rates but require high levels of expertise and substantial resources. A popular surgical treatment aimed at improving the biomechanics-valgus intertrochanteric osteotomy-optimizes conditions for fracture healing by converting shear forces across the fracture site into compressive forces. Numerous variations of this surgical procedure have been developed and successfully applied in clinical practice. As a result, the proximal femoral orientation for obtaining a good functional outcome has evolved over the years, and the present concept of altering the proximal femoral anatomy as little as possible has arisen. This technical objective supports attaining union as well as a good functional outcome, since excessive valgus can lead to increased joint reaction forces. This review summarizes the historical and current literature on valgus intertrochanteric osteotomy treatment of nonunion neck of femur, with a focus on factors predictive of good functional outcome and potential pitfalls to be avoided as well as controversies surrounding this procedure.

    Chronic varus instability of the hallux interphalangeal joint is a rare injury, and only a few reports of this injury have been published. In some studies, this injury has been related to taekwondo. Taekwondo is an essential martial art in the Korean military. We have described a case of varus instability of the hallux interphalangeal joint in a professional soldier who had practiced taekwondo for 5 years and the surgical outcome after reconstruction of the lateral collateral ligament with the fourth toe extensor tendon.

    ABSTRACT OBJECTIVE : The purpose of this study was to evaluate the performance of valgus intertrochanteric osteotomy in femoral neck non-union. METHODS : Forty-two patients with femoral neck fractures with non-union treated using Pauwels' intertrochanteric osteotomy were reviewed. Demographics, time elapsed between fracture and surgery, follow--up, osteosynthesis used, Garden's classification, limb shortening, and x-rays were evaluated. RESULTS : Twenty-two men and 20 women were reviewed. The youngest patient was 18 years old and the oldest 65 years old, with a mean age of 42.4 years (±11.2). The minimum follow-up was 2 years, with a mean of 10.2 years. The average time elapsed between initial fracture and osteotomy was 6.5 months. Twel-ve cases were neglected femoral neck fractures. Nineteen patients were classified as Garden III, and 23 patients as Garden IV. After valgus osteotomy, non-union healing was observed in 38 patients (38/42; 90.4%). Healing of thirty-seven cases of pseudoarthrosis were obtained after the first-attempt osteotomy, and one case required two operations for healing. The osteotomy failed in four cases. Conside-ring the healed osteotomies, good to excellent functional results were achieved in 80.9% (34/42) of the patients. Total hip replacement was subsequently performed in 14.2% (6/42) of the patients for unfavoura-ble outcomes (two for cutting out, two for osteonecrosis, and two for osteoarthritis). CONCLUSIONS : Valgus intertrochanteric osteotomy has a high success rate in archiving healing in femoral neck non-union with good functional results. It is a biological and effective method.

    Hallux varus is defined as a medial deviation of the phalanx at the first metatarsophalangeal joint and can be congenital or acquired. Brachymetatarsia is defined as shortening of the metatarsal bones. A combination of hallux varus and brachymetatarsia is rare. A 15-year-old girl presented to our outpatient clinic complaining of problems with her feet. A distinctive hallux varus was present bilaterally combined with a brachymetatarsia of the first metatarsals. The patient reported discomfort. She was restricted in her activities and had severe psychological strain owing to the deformity. We decided on surgery. First, a Pennig MiniFixator for callus distraction of the first metatarsal bone was applied. Owing to the increased plantar subluxation of the phalanx during distraction, an extension of the external fixator was administered so that the hallux could be repositioned to a physiologically satisfying position. After sufficient callus formation, the hardware was removed 14 weeks after surgery. Thereafter, the phalanx moved back to the subluxed position. Finally, an arthrodesis of the first metatarsophalangeal joint was performed with a locking plate. Surgery should not be made only for cosmesis and associated psychological aspects; but, discomfort should be the deciding factor. The postoperative clinical and cosmetic results in our case were good, and the patient was quite satisfied. There was no longer any preoperative discomfort and pain. PMID:24504582

  17. Knee valgus angle during landing tasks in female volleyball and basketball players.

    Increased knee valgus angles have been associated with an increased risk of a variety of knee injuries. It has yet to be established if knee valgus angles during jump landing tasks differ between jumping sports with relatively higher and lower knee injury rates-namely, basketball and volleyball. Any difference in knee angles on landing may be related to sport-specific differences, which may in turn relate to the different injury risk rates. Fifteen elite female basketball and volleyball players had their knee valgus angles assessed during 2 landing tasks: 1 bilateral (drop jump landing) and 1 unilateral (step landing task). During the drop jump task knee valgus angle was significantly greater in the basketball group (p = 0.017) in the right knee, but there was no significant difference in performance between sports in the left knee (p = 0.67). During the step landing task volleyball players had significantly greater knee valgus angles than basketball players for both the left (p = 0.018) and right (p = 0.025) knees. The basketball group showed superior control of knee valgus during the unilateral task, which may be related to sport-specific skills. The basketball players showed significant asymmetry in knee valgus angle during bilateral drop jump landings; this finding reflects those of previous studies and may be related to the relative increased knee injury risk reported for this population group.

    Few studies have investigated the complications that occur after hallux interphalangeal joint arthrodesis. The present study evaluated complications in 152 patients aged 18 to 80 years from 2005 to 2012 from 4 different academic institutions after hallux interphalangeal joint arthrodesis. Overall, 65.8% of the patients had ≥1 complication. Infections occurred in 16.5%, dehiscence in 12.5%, and reoperations in 27.0%. The clinical nonunion rate was ≥17.8%, and the radiographic nonunion rate was ≥13.8%. After logistic regression analysis, only the study site and peripheral neuropathy were associated with having ≥1 complication (p < .01 and p < .05, respectively). Single screw fixation compared with other fixation did not have a statistically significant influence on the postoperative complications. However, when fixation was expanded to 4 categories, single screw fixation had lower infection and reoperation rates than either crossed Kirschner wires or other fixation category but not compared with crossed screws on multivariate logistic regression analysis. Although additional studies are warranted, the findings from the present study might aid in both the prognosis of complications and the support of the use of a single screw over crossed Kirchner wire fixation in hallux interphalangeal joint arthrodesis.

    Valgus elbow stress leads to medial tension and lateral compression injuries in baseball pitchers of all ages. This study was undertaken to investigate the relationship between elbow stress in professional baseball pitchers and the kinematic parameters of pitching mechanics. This was done in an attempt to understand valgus extension overload better and in an effort to improve preventive and rehabilitative protocols. High-speed video data were collected on 40 professional pitchers in game situations during the 1998 and 1999 Cactus League season in Arizona, as part of Major League Baseball Spring Training. A multiple linear regression analysis was used to relate elbow valgus to kinematic parameters of pitching mechanics. The resulting analysis produced an adjusted multiple R2 value of 0.974, indicating that nearly 100% of the variance in valgus stress on the elbow was explained by the parameters in the regression equation. This ability to explain over 97% of the variance in valgus stress is significant. The parameters of pitching mechanics related to elbow valgus may be assessed and optimized, if necessary, in order to decrease the magnitude of elbow stress in pitching.

    Despite general agreement on the effects of knee valgus and internal tibial rotation on anterior cruciate (ACL) loading, compelling debate persists on the interrelationship between these rotations and how they contribute to the multi-planar ACL injury mechanism. This study investigates coupling between knee valgus and internal tibial rotation and their effects on ACL strain as a quantifiable measure of injury risk. Nineteen instrumented cadaveric legs were imaged and tested under a range of knee valgus and internal tibial torques. Posterior tibial slope and the medial tibial depth, along with changes in tibiofemoral kinematics and ACL strain, were quantified. Valgus torque significantly increased knee valgus rotation and ACL strain (p<0.02), yet generated minimal coupled internal tibial rotation (p=0.537). Applied internal tibial torque significantly increased internal tibial rotation and ACL strain and generated significant coupled knee valgus rotation (p<0.001 for all comparisons). Similar knee valgus rotations (7.3° vs 7.4°) and ACL strain levels (4.4% vs 4.9%) were observed under 50 N-m of valgus and 20 N-m of internal tibial torques, respectively. Coupled knee valgus rotation under 20 N-m of internal tibial torque was significantly correlated with internal tibial rotation, lateral and medial tibial slopes, and medial tibial depth (R2>0.30; p<0.020). These findings demonstrate uni-directional coupling between knee valgus and internal tibial rotation in a cadaveric model. Although both knee valgus and internal tibial torques contribute to increased ACL strain, knee valgus rotation has the ultimate impact on ACL strain regardless of loading mode. PMID:26070647

    The effect of a valgus knee brace and a lateral wedged insole on knee and ankle kinematics and kinetics was evaluated in ten patients with medial knee osteoarthritis (OA). The knee orthosis was tested in two valgus adjustments (4° and 8°), and the laterally wedged insole was fabricated with an inclination of 4°. A motion capture system and force platforms were used for data collection and joint moments were calculated using inverse dynamics. The valgus moment applied by the orthosis was also measured using a strain gauge implemented in the orthosis' rotational axis. For the second peak knee adduction moment, decreases of 18%, 21%, and 7% were observed between baseline and test conditions for the orthosis in 4° valgus, in 8° valgus, and insole, respectively. Similar decreases were observed for knee lever arm in the frontal plane. Knee adduction angular impulse decreased 14%, 18%, and 7% from baseline to conditions for the orthosis in 4° valgus, in 8° valgus, and insole, respectively. Knee angle in the frontal plane reached a more valgus position during gait using the valgus knee brace. The valgus moment applied by the orthosis with 8° valgus adjustment was 30% higher than with 4° valgus adjustment. The valgus knee orthosis was more effective than the laterally wedged insole in reducing knee adduction moment in patients with medial knee OA.

    Total knee arthroplasty following valgus deformity is a challenging procedure due to the unique set of problems that must be addressed. The aim of this study is to determine, with a finite element analysis, the load distribution for an inclined valgus prosthetic balanced knee and to compare these results with those of a prosthetic balanced knee with an uninclined interline. Computational simulations, using finite element analysis, focused on a comparision between load intensity and distribution for these situations. We studied valgus inclination at 3 and 8 degrees. We noticed that for an inclination of 3 degrees, the forces are distributed almost symmetrically on both condyles, similar to the distribution of forces in the uninclined interline case. The maximum contact pressure is greater, increasing from 15 MPa to 19.3 MPa (28%). At 8 degrees of inclination, the contact patch moved anterolateraly on the tibia, meaning that the tibial condyles will be unequally loaded. The maximum contact pressure increases to 25 MPa (66%). These greater forces could lead to polyethylene wear and collapse. Additional tibial resection could be a useful method for balancing in severe valgus knee, when valgus inlination does not exceed 3 degrees. PMID:23464776

    The purpose of this study was to establish a method for measuring the knee valgus angle from the anatomical and mechanical axes on three-dimensional reconstruction imaging models, and to use this method for estimating an average knee valgus angle value for northern Chinese adults. Computed tomographic angiography data in DICOM format for 128 normal femurs from 64 adult subjects were chosen for analysis. After the femur images were subjected to three-dimensional reconstruction, the deepest point in the intercondylar notch (point A), the midpoint of the medullary cavity 20 cm above the knee-joint line (point B), and the landmark of the femoral head rotation center (point C) were identified on each three-dimensional model. The knee valgus angle was defined as the angle enclosed by the distal femoral anatomical axis (line AB) and the femoral mechanical axis (line AC). The average (mean±SD) of knee valgus angle for the 128 femurs was 6.20°±1.20° (range, 3.05° to 10.64°). Significant positive correlations were found between the knee valgus angles of the right and left sides and between the knee valgus angle and age. During total knee arthroplasty, choosing a valgus cut angle of approximately 6° may achieve a good result in reestablishing the natural mechanical alignment of the lower extremity for patients of northern Chinese ethnicity. Larger valgus cut angles should be chosen for older patients. PMID:25091990

    The general purpose of this study was to assess the gait symmetry for Talus Valgus deformity based on experimental kinematic analysis. As this foot condition generally occurs in children, the study is focused on two children having five years old, one being healthy, as control subject, and the second one having bilateral Talus Valgus deformity. Kinematic experimental analysis was conducted using Zebris CMS-HS Measuring System. The bilateral symmetry was analyzed using two methods: index of symmetry (SI) calculated for spatio-temporal parameters (stance phase, swing phase, and step length) and kinematic parameter (maximum value of dorsiflexion - plantar flexion angle in the ankle joint), and an unpaired t-test to compare the variation of means values of dorsiflexion - plantar flexion angle in ankle joint for both left and right side. The study evidenced a good bilateral symmetry in case of the control subject and quantified the asymmetry in case of subject with Talus Valgus deformity.

    This study evaluated outcomes of surgical treatment for carpal valgus in New World camelids and correlated successful outcome (absence of carpal valgus determined by a veterinarian) with patient characteristics and radiographic features. Univariable and multivariable analyses of retrospective case data in 19 camelids (33 limbs) treated for carpal valgus between 1987 and 2010 revealed that procedures incorporating a distal radial transphyseal bridge were more likely (P = 0.03) to result in success after a single surgical procedure. A greater degree of angulation (> 19°, P = 0.02) and younger age at surgery (< 4 months, P = 0.03) were associated with unsuccessful outcome. Overall, 74% of limbs straightened, 15% overcorrected, and 11% had persistent valgus following surgical intervention. To straighten, 22% of limbs required multiple procedures, not including implant removal. According to owners, valgus returned following implant removal in 4 limbs that had straightened after surgery.

Methods Three finite elements models have been developed: a normal one, and two varus and valgus knee ones. Results The obtained results reveal interesting consequences deriving by a wrong disposition of parts which compose the skeletal chain of the leg. Conclusion The most dangerous conditions occur in the contact interface between pelvis and hip of the femur, for the valgus knee configuration, and for the varus one, at the contact interface around the knee zone.

    2016-01-01

    Background: An ideal approach for valgus knees must provide adequate exposure with minimal complications due to approach per se. Median parapatellar approach is most commonly used approach in TKA including valgus knees. A medial subvastus approach is seldom used for valgus knees and has definite advantages of maintaining extensor mechanism integrity and minimal effect on patellar tracking. The present study was conducted to evaluate outcomes of total knee arthroplasty (TKA) and efficacy of subvastus approach in valgus knees in terms of early functional recovery, limb alignment and complications. Materials and Methods: We retrospectively reviewed 112 knees with valgus deformity between January 2006 and December 2011. All patients were assessed postoperatively for pain using Visual Analog Scale (VAS) and quadriceps recovery in form of time to active straight leg raising (SLR) and staircase competency and clinical outcomes using American Knee Society (AKS) score and radiographic evaluation with average followup of 40 months (range 24–84 months). Results: The mean VAS on postoperative day (POD) 1 and POD2 at rest was 2.73 and 2.39, respectively and after mobilization was 3.28 and 3.08, respectively (P < 0.001). The quadriceps recovery was very early and 92 (86.7%) patients were able to do active SLR by POD1 with mean time of 21.98 h while reciprocal gait and staircase competency was possible at 43.05 h. The AKS and function score showed significant improvement from preoperative mean score of 39 and 36 to 91 and 79 (P < 0.001), respectively, and the mean range of motion increased from 102° preoperatively to 119° at recent followup (P < 0.001). The mean tibiofemoral valgus was corrected from preoperative 16° (range 10°–35°) to 5° (range 3°–9°) valgus (P < 0.001). Conclusions: Mini-subvastus quadriceps approach provides adequate exposure and excellent early recovery for TKA in valgus knees, without increase in incidence of complications. PMID:26955174

    The hallux rigidus, especially in advanced stage, has always been a challenge as regards the surgical treatment. Over the years there have been various surgical techniques proposed with the aim of relieving pain, correcting deformity and maintain a certain degree of movement. For some years we have addressed the problem with the replacement metatarsophalangeal joint arthroplasty with Reflexion system. As far as our experience we have operated and monitored 25 patients (18 females and 7 males) of mean age 58.1 years, operated with this technique from June 2008 to June 2011. It reached an average ROM of 72° (extension and flexion 45° and 27°) with a good functional recovery in 8 patients, and this articulation was good (50° - 40°) in 12 patients and moderate in 5 with a articular range from 40°- 30°. The clinical results, according to our experience, appear to be favorable, as even patient satisfaction is complete.

    Deficits in proximal hip strength or neuromuscular control may lead to dynamic lower extremity valgus. Measures of dynamic lower extremity valgus have been previously shown to relate to increased risk of several knee pathologies, specifically anterior cruciate ligament ruptures and patellofemoral pain. Therefore, hip-focused interventions have gained considerable attention and been successful in addressing these knee pathologies. The purpose of the review was to identify and discuss hip-focused exercise interventions that aim to address dynamic lower extremity valgus. Previous electromyography, kinematics, and kinetics research support the use of targeted hip exercises with non-weight-bearing, controlled weight-bearing, functional exercise, and, to a lesser extent, dynamic exercises in reducing dynamic lower extremity valgus. Further studies should be developed to identify and understand the mechanistic relationship between optimized biomechanics during sports and hip-focused neuromuscular exercise interventions.

    Prostate cancer is one of the most common carcinomas in Asia, as well as all over the world. The vast majority of prostate cancer patients present with bone metastases, which mainly involve the axial bones, with pain as the most common symptom. The present study reports the first case of prostate cancer metastasis to the hallux in a 73-year-old man who presented with pain and a swollen phalanx of the left hallux. This symptom developed gradually over a period of several months and could not be improved with the common treatments. Due to a pathological fracture, amputation of the left phalanx was performed. Notably, the immunohistochemical examinations of the surgical sample demonstrated the presence of a metastatic lesion from prostate cancer. The present study describes an unusual presentation involving phalangeal metastasis in a prostate cancer patient, and a systematic review of reported cases of rare metastatic events in prostate cancer is also discussed.

    The late diagnosis of squamous cell carcinoma of the hallux in an aged patient on second-line therapy led to a trans-proximal phalanx amputation. This is a rare lesion affecting the toes which may compromise the functional prognosis of the foot. This clinical case report with review of the literature aims to highlight the difficulties of diagnosis and indications for amputation. PMID:27642450

  16. Foot kinematics in walking on a level surface and on stairs in patients with hallux rigidus before and after cheilectomy

    PubMed Central

    2014-01-01

    Background Walking down stairs is a clinically relevant daily activity for older persons. The aim of this pilot study was to investigate the impact of cheilectomy on walking on level ground and on stairs. Methods 3D motion analysis of foot kinematics was performed in eight patients with hallux rigidus and 11 healthy control participants with a 12-camera system, using the Heidelberg foot measurement method before and one year after surgery. The clinical results were documented using the AOFAS Scale. Results The range of motion of the first metatarsophalangeal joint did not improve after the operation under any gait condition. Preoperatively, hallux dorsi-/plantarflexion in level walking was 11.9° lower in patients than in controls (p = 0.006), postoperatively 14.5° lower (p = 0.004). Comparing walking conditions in patients, hallux dorsi-/plantarflexion was significantly higher in level walking than in climbing stairs (difference up stairs – level: -8.1°, p = 0.018). The AOFAS Scale improved significantly from 56.9 ± 19.9 points (mean ± SD), preoperatively, to 75.9 ± 13.9 points, postoperatively (p = 0.027). Conclusions Cheilectomy is appropriate for reducing symptoms of hallux rigidus. However, neither a positive influence on the range of motion in walking on level ground and on stairs nor a functional improvement was observed in this group of patients.

    Impaired proprioception and poor muscular stabilization in the frontal plane may lead to knee instability during functional activities, a common complaint in persons with knee osteoarthritis (KOA). Understanding these frontal plane neuromechanical properties in KOA will help elucidate the factors contributing to knee instability and aid in the development of targeted intervention strategies. The study objectives were to compare knee varus-valgus proprioception, isometric muscle strength, and active muscular contribution to stability between persons with medial KOA and healthy controls. We evaluated knee frontal plane neuromechanical parameters in 14 participants with medial KOA and 14 age- and gender-matched controls, using a joint driving device (JDD) with a customized motor and a 6-axis force sensor. Analysis of covariance with BMI as a covariate was used to test the differences in varus-valgus neuromechanical parameters between these two groups. The KOA group had impaired varus proprioception acuity (1.08 ± 0.59° vs. 0.69 ± 0.49°, p < 0.05), decreased normalized varus muscle strength (1.31 ± 0.75% vs. 1.79 ± 0.84% body weight, p < 0.05), a trend toward decreased valgus strength (1.29 ± 0.67% vs. 1.88 ± 0.99%, p = 0.054), and impaired ability to actively stabilize the knee in the frontal plane during external perturbation (4.67 ± 2.86 vs. 8.26 ± 5.95 Nm/degree, p < 0.05). The knee frontal plane sensorimotor control system is compromised in persons with medial KOA. Our findings suggest varus-valgus control deficits in both the afferent input (proprioceptive acuity) and muscular effectors (muscle strength and capacity to stabilize the joint). PMID:24321442

    There is a growing concern about elderly valgus impacted proximal humeral fractures. The aim of this study was to evaluate the treatment and clinical outcomes following minimal invasive percutaneous plate osteosynthesis (MIPPO) with the proximal humeral internal locking system (PHILOS) for the treatment of elderly valgus impacted proximal humeral fracture. Between May 2008 and May 2012, 27 patients (average age 67.3, range 61-74) with valgus impacted proximal humeral fractures were enrolled in the study. The patients were treated with MIPPO using PHILOS-plate through the anterolateral delta-splitting approach. Rehabilitation exercises were done gradually. The NEER score and Constant-Murley score were used to evaluate shoulder function. All the patients were followed up by routine radiological imaging and clinical examination. There were 15 cases of II-part greater tuberosity fractures, 10 cases of III-part greater tuberosity fractures, and 2 cases of IV-part fractures according to the NEER classification. The surgery was successful in all patients with an average follow-up of 20.8 (range: 11-34) months. The fractures united in an average of 7.2 (6-14) weeks without implant loosening. According to NEER score, there were 17 excellent, 7 satisfactory, 2 unsatisfactory, and 1 poor. The mean Constant-Murley score was 89.4 ± 4.35. No complication including axillary nerve damage, postoperative nerve or vessel damage, infections, DVT, or death was observed. In conclusion, the MIPPO technique with the PHILOS through the anterolateral delta-splitting approach seems to be a safe and easy treatment for elderly valgus impacted proximal humeral fractures. A case-control study and longer follow-up time are needed.

    This study evaluated a technique using the anteroposterior axis of the distal femur, rather than the transepicondylar or posterior femoral condylar axis, to establish rotational alignment of the femoral component in valgus knees. The anteroposterior axis of the distal femur was defined by a line through the deepest part of the patellar groove anteriorly and the center of the intercondylar notch posteriorly. Total knee arthroplasty was done in 46 valgus knees between 1980 and 1986 using the posterior femoral condyles as landmarks for rotational alignment. From January 1986 through January 1992 total knee arthroplasty was done in 107 valgus knees using the anteroposterior axis for rotational alignment of the femoral component. In the group of knees using the posterior condylar axis, medial tibial tubercle transfer was needed intra-operatively in 8 knees to prevent lateral dislocation of the patella. In the first 2 postoperative years, 4 knees had recurrent patellar dislocation or subluxation that required surgical correction. In the group of knees using the anteroposterior axis, patellar tracking problems that required realignment were significantly reduced. One knee required medial tibial tubercle transfer to correct a Q angle > 20 degrees. In the remaining knees, the Q angle was < 10 degrees, and patellar tracking was acceptable. Two years after surgery, no knees had patellar instability.

    Abstract Objective To describe a common musculoskeletal disorder from a chiropractic management prospective, subsequently to stimulate further research into the chiropractic therapeutic effects on such cases and to contribute to chiropractic literature. Clinical Features A 27-year-old, 76” male student often involved in athletic activities, had a sudden onset of continuous localized pain in the medial aspect of the mid and forefoot on the right side for 1-and-a half months. The onset of pain was related to an accidental injury while playing basketball. The pain worsened every time during and after playing basketball and other weight-bearing activities such as walking upstairs and is palliated with physical rest. He tried Biofreeze and ice application for several times immediately after the injuries which help to some extent to relieve pain and swelling, but he did not seek any other professional care. The condition had been improving slowly even before he came to the clinic although the patient described the pain as 5/10 on the Borg pain scale when he came to the clinic for the first time. The characteristic local findings were a mildly hyper-pronated right foot, mildly asymmetric soft-tissue and bony contours, tenderness, stiffness and decreased range of motion (ROM) at the first metatarsophalangel and adjacent joints on the medial aspect of the midfoot decreased fluid motions in the concerned joints on the chiropractic evaluation and some abnormal wearing in the shoes. Intervention and Outcome He was managed with chiropractic manipulation combined with other conservative measures. Range of motion (ROM), Borg Pain Scale and an orthopedic test (Morton's Test) were used as the outcome measures. The subject showed a favorable response to the conservative (chiropractic) care. Conclusion Although hallux rigidus is one of the most common musculoskeletal degenerative conditions, our conservative management received a favorable response but there has been little

    Knee joint stability is important in maintaining normal joint motion during activities of daily living. Joint instability not only disrupts normal motion but also plays a crucial role in the initiation and progression of osteoarthritis. Our goal was to examine knee joint coronal plane stability under varus or valgus loading and to understand the relative contributions of the mechanisms that act to stabilize the knee in response to varus-valgus moments, namely, load distribution between the medial and lateral condyles and the ligaments. A robot testing system was used to determine joint stability in human cadaveric knees as described by the moment versus angular rotation behavior under varus and valgus loads at extension and at 30 deg and 90 deg of flexion. The anatomic knee joint was more stable in response to valgus than varus moments, and stability decreased with flexion angle. The primary mechanism for providing varus-valgus stability was the redistribution of the contact force on the articular surfaces from both condyles to a single condyle. Stretching of the collateral ligaments provided a secondary stabilizing mechanism after the lift-off of a condyle occurred. Compressive loads applied across the knee joint, such as would occur with the application of muscle forces, enhanced the ability of the articular surface to provide varus-valgus moment, and thus, helped stabilize the joint in the coronal plane. Coupled internal/external rotations and anteroposterior and medial-lateral translations were variable and in the case of the rotations were often as large as the varus-valgus rotations created by the applied moment.

    Hallux rigidus describes the osteoarthritis of the first metatarsophalangeal joint. It was first mentioned in 1887. Since then a multitude of terms have been introduced referring to the same disease. The main complaints are pain especially during movement and a limited range of motion. Radiographically the typical signs of osteoarthritis can be observed starting at the dorsal portion of the joint. Numerous classifications make the comparison of the different studies difficult. If non-operative treatment fails to resolve the symptoms operative treatment is indicated. The most studied procedure with reproducible results is the arthrodesis. Nevertheless, many patients refuse this treatment option, favouring a procedure preserving motion. Different motion preserving and joint sacrificing operations such as arthroplasty are available. In this review we focus on motion and joint preserving procedures. Numerous joint preserving osteotomies have been described. Most of them try to relocate the viable plantar cartilage more dorsally, to decompress the joint and to increase dorsiflexion of the first metatarsal bone. Multiple studies are available investigating these procedures. Most of them suffer from low quality, short follow up and small patient numbers. Consequently the grade of recommendation is low. Nonetheless, joint preserving procedures are appealing because if they fail to relief the symptoms an arthrodesis or arthroplasty can still be performed thereafter. PMID:24649409

    Triggering of the big toe, or hallux saltans, is commonly due to stenosing tenosynovitis of the flexor hallucis longus at the fibro-osseous tunnel below the sustentaculum tali. It is a rare condition described mainly in female ballet dancers. This is hypothesized to be due to the en pointe position used in ballet, which puts enormous supraphysiologic loads on the flexor hallucis longus, predisposing it to injury. Trigger hallux is extremely uncommon in the general population. We are reporting a case of hallux saltans in an unskilled manual laborer, with the site of tendon entrapment just proximal to the medial malleolus in the distal leg, a hitherto unreported location of stenosis.

    The goal of this study was to determine the effects of peak knee valgus angle and peak knee abductor moment on the anterior, medial, and lateral tibial translations (ATT, MTT, LTT) in the "at risk" female knee during drop landing. Fifteen female subjects performed drop landings from 40 cm. Three-dimension knee motion was simultaneously recorded using a high speed, biplane fluoroscopy system, and a video-based motion analysis system. Valgus knee angles and knee abduction moments were stratified into low, intermediate, and high groups and peak ATT, MTT, and LTT were compared between these groups with ANOVA (α = 0.05). Significant differences were observed between stratified groups in peak knee valgus angle (p < 0.0001) and peak knee abduction moment (p < 0.0001). However, no corresponding differences in peak ATT, LTT, and MTT between groups exhibiting low to high-peak knee valgus angles (ATT: p = 0.80; LTT: p = 0.25; MTT: p = 0.72); or, in peak ATT (p = 0.61), LTT (p = 0.26) and MTT (p = 0.96) translations when stratified according to low to high knee abduction moments, were found. We conclude that the healthy female knee is tightly regulated with regard to translations even when motion analysis derived knee valgus angles and abduction moments are high.

    The degree of hallux abduction in extant and fossil hominoids is analysed in terms of geometric relationships between the first metatarsal and the medial cuneiform and quantified by angular data, in relation to grasping ability and locomotor pattern. The 'australopithecine' pattern corresponds to an abducted first podal ray with some grasping abilities and seems to be derived from a ' Proconsul-like' pattern rather than a 'living African great ape-like' pattern. The Olduvai Hominid 8 condition closely resembles that of the modern human which corresponds to a full bipedalism.

    Valgus bending and shearing of the knee have been identified as primary mechanisms of injuries in a lateral loading environment applicable to pedestrian-car collisions. Previous studies have reported on the structural response of the knee joint to pure valgus bending and lateral shearing, as well as the estimated injury thresholds for the knee bending angle and shear displacement based on experimental tests. However, epidemiological studies indicate that most knee injuries are due to the combined effects of bending and shear loading. Therefore, characterization of knee stiffness for combined loading and the associated injury tolerances is necessary for developing vehicle countermeasures to mitigate pedestrian injuries. Isolated knee joint specimens (n=40) from postmortem human subjects were tested in valgus bending at a loading rate representative of a pedestrian-car impact. The effect of lateral shear force combined with the bending moment on the stiffness response and the injury tolerances of the knee was concurrently evaluated. In addition to the knee moment-angle response, the bending angle and shear displacement corresponding to the first instance of primary ligament failure were determined in each test. The failure displacements were subsequently used to estimate an injury threshold function based on a simplified analytical model of the knee. The validity of the determined injury threshold function was subsequently verified using a finite element model. Post-test necropsy of the knees indicated medial collateral ligament injury consistent with the clinical injuries observed in pedestrian victims. The moment-angle response in valgus bending was determined at quasistatic and dynamic loading rates and compared to previously published test data. The peak bending moment values scaled to an average adult male showed no significant change with variation in the superimposed shear load.

    Achieving frontal plane alignment of the ankle joint during total ankle replacement is essential for long-term success. Tendon and ligament lengthening, ligament reinforcement, tendon transfer, nonanatomic tendon transfer ligament reconstruction, and periarticular osteotomies are safe, straightforward, minimally invasive, and reproducible procedures to correct varus and valgus deformities associated with end-stage degenerative joint disease. Using reproducible topographic anatomic landmarks is essential to these techniques properly and limit complications. The approach to frontal plane deformities is stepwise, with liberal use of tendon and ligament lengthening and reconstruction, a low threshold for nonanatomic tendon transfer ligament reconstructions, and tendon transfers and/or periarticular osteotomies.

    Background Although the valgus subtrochanteric osteotomy is considered as a standard surgical treatment for coxa vara, there is no consensus on the optimal method of fixation and osteotomy technique. Fixation of the osteotomy has been achieved by various methods including external fixation and internal fixation with pins and cerclage and a variety of plates. The aim of this study is the evaluation of the results of developmental coxa treated by Y intertrochanteric valgus osteotomy fixed with a T-buttress plate compared with other methods of fixation in the literature. Methods Eighteen corrective valgus intertrochanteric femoral osteotomies were performed in 18 patients (18 hips) for treatment of unilateral developmental coxa vara deformity and fixed with a T plate. There were 12 males and 6 females. The right hip was affected in 10 patients and the left hip in 8 patients. Clinically, patients were evaluated by Larson hip score. Radiographically, anteroposterior view of the pelvis and frog leg lateral views of the affected hip were taken preoperatively and compared with the findings at the final follow-up. Results The average follow-up was 29 months (range, 24 to 36 months). Clinical results showed improvement of the mean Larson hip score from 57.8 to 97.0 (p < 0.001). Radiological results showed that all osteotomies were completely united in 2.4 months (range, 2 to 3 months) with the achievement of the planned correction angle. The average correction of Hilgenreiner's epiphyseal angle improved from 78.2° to 27.8° (p < 0.001) at the final follow-up. The femoral neck shaft angle was improved from 93.7° to 129.9° (p < 0.001) at the final follow-up. Shortening of the affected limb was corrected from 2.8 cm to 1.3 cm (p < 0.001) at the last follow-up. No major serious complications were recorded in the present study. Conclusions Intertrochanteric valgus osteotomy of the proximal femur fixed with a T plate may be efficient for treatment of developmental coxa vara

    2008-01-01

    Palliative Schanz proximal femoral valgus osteotomy is considered a common option for treatment of irreducible hip dislocation in cerebral palsy. From 1992 to 2005, Schanz osteotomy was indicated on 55 occasions in 35 nonambulatory patients with the quadriplegic form of cerebral palsy aged 9–18. Postoperatively, the main emphasis focussed on clinical presentation, improvement of hip range of motion, and pain relief. X-rays were carried out at three, six, and 12 months postoperatively with subsequent average follow up 98 ± 4.5 months. In all patients, the range of hip abduction and flexion increased. In 54 (98.2%) cases painful symptoms significantly improved. One patient (1.8%) had a subsequent femoral head excision because of persistent hip pain. Transient hip pain persisted in four patients (7.3%). Schanz valgus osteotomy improves the hip range of motion, relieves pain, and facilitates care of the patient. Schanz femoral osteotomy is a less invasive method compared to proximal femoral excision and should preferably be used in older children with neurogenic hip dislocation in whom reconstructive surgery is not indicated.

    Supracondylar fractures are commonly encountered in the pediatric population. An impacted radial or ulnar column may result in the deviation of the elbow axis in the frontal plane clinically seen as cubitus varus or valgus. Antegrade nailing has become a feasible alternative to treat supracondylar fractures. It is not known whether it can prevent the development of cubitus varus or valgus in the cases of fractures with impacted columns. Between 1994 and 2009, 264 supracondylar humeral fractures were treated. Nineteen patients presented with either an impacted ulnar (n = 12) or radial (n = 7) column and were included in the study. The average elbow angle in fractures with impacted radial column was 159° mean (range 153-167°) compared with 179° (range 173-184°) in fractures with an impacted ulnar column. After closed reduction and antegrade nailing, the elbow angle was restored to normal values. At follow-up examination after a mean of 3.8 years (range 2.4-7.6 years), no further changes of the humeral-ulnar angle were seen. We are able to show that antegrade nailing is a safe method to treat supracondylar humeral fractures with impacted columns.

    Deformities of the feet in children can influence not only optimal foot development but also the development of other body segments. The aim of the study was to compare the hip and pelvis kinematics in groups of children with and without valgus deformity of the hindfoot. Three groups of children participated in the study: bilateral hindfoot valgosity (11 children, age 5.4 ± 1.4 years), unilateral hindfoot valgosity (14 children, age 5.6 ± 1.6 years) and the control group (8 children, 4.8 ± 1.2). Hindfoot valgus angle was measured clinically during standing. Hindfoot valgosity was considered in the range of 6 to 20 degrees. Kinematic data from five trials for each child was obtained using the Vicon MX system (six infrared cameras, frequency 200 Hz, Vicon Motion Systems, Oxford, UK). The results of our study showed significantly higher pelvic anteversion during the whole gait cycle for both unilateral and bilateral hindfoot valgosity children and significantly higher hip external rotation during the first half of the stance phase in bilateral deformity. The differences in the hip and pelvis kinematics, when compared to the control group, are higher for the group with bilateral deformity than in the group with unilateral deformity.

    The stability of a total knee arthroplasty is determined by the ability of the prosthesis components in concert with supportive bone and soft tissue structures to sufficiently resist deforming forces transmitted across the knee joint. Constrained prostheses are used in unstable knees due to their ability to resist varus and valgus transformative forces across the knee. Constraint requires inherent rigidity, which can facilitate early implant failure. The purpose of this study was to describe the comparative indications for surgery and postoperative outcomes of varus valgus constrained knee (VVK) and rotating-hinge knee (RHK) total knee arthroplasty prostheses. Seven retrospective observational studies describing 544 VVK and 254 RHK patients with an average follow-up of 66 months (range, 7-197 months) were evaluated. Patients in both groups experienced similar failure rates (P=.74), ranges of motion (P=.81), and Knee Society function scores (P=.29). Average Knee Society knee scores were 4.2 points higher in VVK patients compared with RHK patients, indicating minimal mid-term clinical differences may exist (P<.0001). Absent collateral ligament support is an almost universal indication for RHK implantation vs VVK. Constrained device implantation is routinely guided by inherent stability of the knee, and, when performed, similar postoperative outcomes can be achieved with VVK and RHK prostheses.

The angle for shoulder flexion and abduction was restricted to 50 and 80 degrees, respectively. Valgus closing-wedge osteotomy followed by the internal fixation using a locking plate was carried out at 12 months after injury. Postoperatively, the head-shaft angle of the humerus improved from 65 to 138 degrees. Active flexion and abduction angles improved from 80 to 135 degrees and from 50 to 135 degrees, respectively. However, the patient complained from a sharp pain with a clicking sound during shoulder abduction even after removal of the locking plate. Since subacromial steroid injection temporarily relieved his shoulder pain, we assumed that the secondary subacromial impingement was provoked after osteotomy. Thus, arthroscopic subacromial decompression was carried out at 27 months after the initial operation, which finally relieved his symptoms. In the valgus closing-wedge osteotomy, surgeons should pay attention to the condition of subacromial space to avoid causing the secondary subacromial impingement. PMID:26000187

    [Purpose] The purpose of this study was to determine the functional differences of the plantar flexion muscles of the hallux and lesser toes during the single leg stance by comparing postural sway in different conditioning contraction interventions. [Subjects] Thirty-four healthy, young males and females participated in this study. [Methods] The front-back and right-left direction components of maximal displacement and postural sway velocity during the single leg stance were measured in various conditioning contraction interventions for the plantar flexion muscles of the hallux or lessor toes. [Results] The main findings of this study were as follows: 1) the front-back direction component of maximal displacement was reduced by conditioning contraction of the plantar flexion muscles of the hallux, and 2) the front-back direction component of the postural sway velocity was reduced by conditioning contraction of the plantar flexion muscles of the lesser toes during the single leg stance. [Conclusion] The plantar flexion muscles of the lesser toes control the postural sway velocity. Furthermore, the plantar flexion muscles of the hallux appear to control the amplitude of postural sway. PMID:26504272

    Increases in the external knee adduction moment (EKAM) have been associated with increased mechanical load at the knee and progression of knee osteoarthritis. Valgus knee braces and lateral wedged insoles are common approaches to reducing this loading; however no study has directly compared the biomechanical and clinical effects of these two treatments in patients with medial tibiofemoral osteoarthritis. A cross-over randomised design was used where each intervention was worn by 28 patients for a two week period. Pre- and post-intervention gait kinematic/kinetic data and clinical outcomes were collected to evaluate the biomechanical and clinical effects on the knee joint. The valgus knee brace and the lateral wedged insole significantly increased walking speed, reduced the early stance EKAM by 7% and 12%, and the knee adduction angular impulse by 8.6 and 16.1% respectively. The lateral wedged insole significantly reduced the early stance EKAM compared to the valgus knee brace (p=0.001). The valgus knee brace significantly reduced the knee varus angle compared to the baseline and lateral wedged insole. Improvements in pain and function subscales were comparable for the valgus knee brace and lateral wedged insole. There were no significant differences between the two treatments in any of the clinical outcomes; however the lateral wedged insoles demonstrated greater levels of acceptance by patients. This is the first study to biomechanically compare these two treatments, and demonstrates that given the potential role of knee loading in osteoarthritis progression, that both treatments reduce this but lateral wedge insoles appear to have a greater effect.

    Female basketball players would appear particularly prone to knee injuries. These injuries have been associated with the nature of the sport, but more specifically with the particular movement strategies adopted. A valgus or abducted position of the knee on landing has been reported to be associated with a number of different knee injuries. Jump-training programs have been reported to improve both landing knee valgus and functional performance. The majority of the jump-training programs have been of 6 weeks' duration, 3 sessions per week often lasting up to 1 hour. For most sports coaches, team conditioners, and athletes, this duration and program length is not acceptable. The aim of this study was to assess if an abridged jump-training program could have similar effects to those previously reported. Fifteen female basketball players had their knee valgus angles assessed during 2 landing tasks, drop jump landing, and when undertaking a jump shot and along with crossover hop distance before and after a progressive jump-training program. The jump-training program lasted 4 weeks, 3 times per week, each session lasting 15 minutes. After training, crossover hop distance showed an average percentage improvement on distance jumped of 73.6% (p = 0.001); the drop jump knee valgus angle in the left leg on average was reduced by 9.8° (p = 0.002), right leg reduced by 12.3° (p = 0.0001); during the jump shot, the knee valgus angle in the left leg showed a mean reduction of 4.5° (p = 0.035), and the right leg was reduced by 4.3° (p = 0.01). The study undertaken achieved comparable results to those previously reported with an abridged program over considerably shortened session duration and training period.

    The cementless Oxford unicompartmental knee replacement has been demonstrated to have superior fixation on radiographs and a similar early complication rate compared with the cemented version. However, a small number of cases have come to our attention where, after an apparently successful procedure, the tibial component subsides into a valgus position with an increased posterior slope, before becoming well-fixed. We present the clinical and radiological findings of these six patients and describe their natural history and the likely causes. Two underwent revision in the early post-operative period, and in four the implant stabilised and became well-fixed radiologically with a good functional outcome. This situation appears to be avoidable by minor modifications to the operative technique, and it appears that it can be treated conservatively in most patients.

    To optimize the diagnosis and treatment for the inborn flat-valgus deformity of the foot (IFVDF), the results of treatment of 78 children, ageing from 1 mo to 12 yrs old, were analyzed. Algorithms of diagnosis and treatment were elaborated. Operative treatment on soft tissues for IFVDF was indicated in the cases of inefficacy or insufficient efficacy of conservative therapy in the age after 1 year old, when a child starts to walk by himself. The proposed method of operative treatment permits to achieve good results and it is less traumatic in comparison with the existing methods. Better results are noted while application of the method in children, ageing from 1 to 4 yrs old.

    Four hand-reared cheetah cubs (Acinonyx jubatus) exhibited progressively severe bilateral valgus deformity of the carpi (CV) during the weaning period. Radiographs of the thoracic limbs suggested normal bone ossification, and serum chemistry was unremarkable. All affected cubs developed CV shortly after the onset of gastroenteritis, which was treated medically, and included use of a prescription diet. A sudden decrease in growth rate was associated with gastrointestinal disease. Before gastroenteritis and CV, affected cubs had higher growth rates than unaffected cubs, despite similar mean daily energy intake. Return to normal thoracic limb conformation was consequent to dietary manipulation (including a reduction in energy intake and vitamin and mineral supplementation), as well as decreased growth rates and recovery from gastroenteritis. The cause of the CV is likely to have been multi-factorial with potentially complex physiological interactions involved.

    We report on 22 patients with chronic grade-2 valgus laxity of the knee combined with chronic anterior cruciate ligament (ACL) insufficiency, in whom the two lesions were addressed at the same surgical setting. At a minimum follow-up of 24 months, clinical and functional variables had improved significantly (P < 0.001), and 20 of the 22 patients (91%) had returned to sport at pre-injury level. There were no operative complications in this series. In selected athletes with chronic symptomatic valgus laxity of the knee combined with ACL insufficiency, surgical repair of the MCL in association with ACL reconstruction is a suitable and reliable option to restore knee stability and allow return to pre-injury activity level.

    Purpose/Background Lower limb asymmetry between dominant and nondominant limbs is often associated with injuries. However, there is a lack of evidence about frontal plane projection angle (FPPA) of the knee joint (knee valgus) during drop vertical jump (DVJ) and forward step-up tasks (FSUP) in young basketball players. Therefore, the purpose of this study was to assess the FPPA (i.e., dynamic knee valgus) via 2D video analysis during DVJ and FSUP tasks in the dominant and nondominant limbs of young male basketball players. Methods Twenty seven young male basketball players (age 14.5 ± 1.3 y, height 161.1 ± 4.1 cm, weight 64.2 ± 10.2 kg) participated in this study. The participants were asked to perform a bilateral DVJ and unilateral FSUP tasks. Kinematic analysis of FPPA was completed via a two-dimensional (2D) examination in order to evaluate the knee valgus alignment during the beginning of the concentric phase of each task. Knee valgus alignment was computed considering the angle between the line formed between the markers at the anterior superior iliac spine and middle of the tibiofemoral joint and the line formed from the markers on the middle of the tibiofemoral joint to the middle of the ankle mortise. Paired t-tests were used to evaluate differences in tasks. Standard error of measurement (SEM) was calculated to establish random error scores. Results There was no difference in knee valgus angle during the DVJ task between dominant (20.2 ± 4.4 º) and nondominant legs (20 ± 4.1 º; p = 0.067). However, a significant difference was noted during FSUP between the non-dominant limb (18.7 ± 3.4 º) when compared to the dominant (21.7 ± 3.5 º; p = 0.001) limb. Conclusion Two dimensional kinematic analysis of knee FPPA may help coaches and other professionals to detect asymmetries between dominant and nondominant limbs, and to develop training programs with the goal of reducing overall lower extremity injury risk

    Valgus foot (VF) is the most common foot deformity in children with cerebral palsy (CP), which seriously affects the foot balance in standing and posture control in walking. Little information about the locus and stress of internal bones was available. To accurately describe the biomechanical behavior of the internal bones of VF in CP, we compared the locus and stress of internal bones between the normal foot (NF) and VF by finite element models. Compared with the NF, displacement of the talus and navicular drop in VF increased by 109% and 171% in vertical direction respectively, and the locus of talus had a tendency to clockwise rotation and downward movement in coronal plane. In addition, the abduction angle of forefoot in VF increased up to 10.3°, which was twice more than that in the NF. Moreover, the lateral metatarsophalangeal joints were upward tilted 6.3° comparing with touchdown posture of NF, and peak von Mises stress of the internal bones in VF model concentrated on the fourth metatarsal. The simulation showed that locus of the forefoot, downward rotation of talus head and navicular drop were meaningful to quantify the collapse of medial longitudinal arch. It would provide some suggestions to the rehabilitation treatments of the CP children's VF.

    Flexor pronator muscles (FPMs) play a key role in stabilizing the elbow joint against valgus forces. However, no studies have investigated the in vivo kinematics of FPMs against these forces on the elbow. This study aimed to clarify the in vivo contribution of each FPM as a dynamic stabilizer in a clinical situation.Twelve healthy volunteers participated in this study. Verbal informed consent was obtained from all subjects. The elbow was flexed to 90 degrees, and the forearm was placed in the neutral position. Manual valgus stress was applied to the elbow joint until maximal shoulder external rotation was achieved. The width of the ulnohumeral joint space and the ulnar shift of the sublime tubercle were measured before and after isometric contraction of FPMs using ultrasonography.The horizontal distances were decreased 1.1±0.6 mm after forearm pronation, 0.6±0.5 mm after wrist palmar flexion, 0.1±0.4 mm after wrist ulnar flexion, and 0.2±0.5 mm after finger flexion. Significant changes were observed during forearm pronation, wrist palmar flexion, and finger flexion but not during wrist ulnar flexion (p<0.05). The sublime tubercle was significantly shifted 0.5±0.1 mm medially after forearm pronation, 0.2±0.1 mm medially after wrist palmar flexion, and 0.1±0.1 mm laterally after wrist ulnar flexion and finger flexion (p<0.05). The FPMs, especially the pronator teres and the flexor carpi radialis, function as dynamic stabilizers against elbow valgus stress. The results of this study may be useful in developing injury prevention and rehabilitation strategies for throwing injuries of the elbow. PMID:25283981

    The purpose of this investigation was to compare valgus/varus knee angles during various jumps and lower body strength between males and females relative to body mass. Seventeen recreationally active females (age: 21.94 ± 2.59 years; height: 1.67 ± 0.05 m; mass: 64.42 ± 8.39 kg; percent body fat: 26.89 ± 6.26%; squat one-repetition maximum: 66.18 ± 19.47 kg; squat to body mass ratio: 1.03 ± 0.28) and 13 recreationally active males (age: 21.69 ± 1.65 years; height: 1.77 ± 0.07 m; mass: 72.39 ± 9.23 kg; percent body fat: 13.15 ± 5.18%; squat one-repetition maximum: 115.77 ± 30.40 kg; squat to body mass ratio: 1.59 ± 0.31) performed a one-repetition maximum in the squat and three of each of the following jumps: countermovement jump, 30 cm drop jump, 45 cm drop jump, and 60 cm drop jump. Knee angles were analysed using videography and body composition was analysed by dual-energy X-ray absorptiometry to allow for squat to body mass ratio and squat to fat free mass ratio to be calculated. Significant differences (P ≤ 0.05) were found between male and female one-repetition maximum, male and female squat to body mass ratio, and male and female squat to fat free mass ratio. Significant differences were found between male and female varus/valgus knee positions during maximum flexion of the right and left leg in the countermovement jump, drop jump from 30 cm, drop jump from 45 cm, and drop jump from 60 cm. Correlations between varus/valgus knee angles and squat to body mass ratio for all jumps displayed moderate, non-significant relationships (countermovement jump: r = 0.445; drop jump from 30 cm: r = 0.448; drop jump from 45 cm: r = 0.449; drop jump from 60 cm: r = 0.439). In conclusion, males and females have significantly different lower body strength and varus/valgus knee position when landing from jumps.

    Total knee arthroplasty (TKA) after valgus proximal tibial osteotomy poses no major difficulties in most cases. There is, however, a small subgroup of severely overcorrected patients in whom TKA is particularly difficult. These patients require special considerations. A complex ligament reconstruction has been developed to allow simultaneous implantation of a minimally constrained total knee prosthesis for patients with failed, severely overcorrected valgus high tibial osteotomies. The technique is described in five patients. The mean age of the group was 57 years and the average follow-up period was 34 months (range, 12-72 months). A 100-point knee-evaluation scale was used to rate the knees before and after TKA. The average pre- and postoperative scores were 50 and 94, respectively. None of the patients was noted to have any more than mild instability in any direction postoperatively. Despite this extensive reconstruction, the group functioned as well as most recipients of more standard primary TKAs and demonstrated it is possible to avoid highly constrained implants, custom prostheses, or major bone grafts.

    Objective To investigate the relationship between the q-angle and anterior knee pain severity, functional capacity, dynamic knee valgus and hip abductor torque in women with patellofemoral pain syndrome (PFPS). Methods This study included 22 women with PFPS. The q-angle was assessed using goniometry: the participants were positioned in dorsal decubitus with the knee and hip extended, and the hip and foot in neutral rotation. Anterior knee pain severity was assessed using a visual analog scale, and functional capacity was assessed using the anterior knee pain scale. Dynamic valgus was evaluated using the frontal plane projection angle (FPPA) of the knee, which was recorded using a digital camera during step down, and hip abductor peak torque was recorded using a handheld dynamometer. Results The q-angle did not present any significant correlation with severity of knee pain (r = −0.29; p = 0.19), functional capacity (r = −0.08; p = 0.72), FPPA (r = −0.28; p = 0.19) or isometric peak torque of the abductor muscles (r = −0.21; p = 0.35). Conclusion The q-angle did not present any relationship with pain intensity, functional capacity, FPPA, or hip abductor peak torque in the patients with PFPS. PMID:27069887

    Purpose The aim of this study was to establish the concurrent validity and reliability of four different two-dimensional (2D) video-based techniques for quantifying frontal plane knee kinematics during a 40 cm double-legged drop jump. Participants and methods A convenience sample of 16 healthy participants (nine males and seven females; age: [mean ± standard deviation] 25.5±2 years; body mass index: 24.33±2.98 kg/m2) participated in this investigation. A total of five trials during a 40 cm drop jump maneuver with a countermovement jump were used as the functional task. Four knee valgus measures, such as two different frontal plane projection angle measures, knee-to-ankle separation ratio (KASR), and knee separation distance (KSD), were measured using 2D and three-dimensional (3D) systems. To generalize to the greater population of possible evaluators, the testers performing the biomechanical analyses were three novice physical therapists. Intra- and intertester intraclass correlation coefficients (ICCs) were estimated for 2D analysis variables. ICCs were estimated for all measures between systems to determine concurrent validity of the 2D system. Results All four 2D measures showed good to excellent reliability (ICC: 0.89–0.99). KASR and KSD showed excellent correlation (ICC: 0.96; 95% CI: 0.82–0.98 and ICC: 0.94; 95% CI: 0.90–0.96, respectively) with the 3D system, while both methods of frontal plane projection angle showed poor to moderate correlation (ICC: 0–0.57) with the 3D system. Conclusion 2D KASR and KSD measures are cost effective, reliable, and highly correlated with the same measures using 3D techniques for the evaluation of knee valgus. PMID:27313480

    2015-01-01

    Recently there has been increased year-round sports participation among children and adolescents with limited to no rest periods. This has led to increases in pediatric repetitive stress injuries, once considered a rarity. Whether in the throwing athlete or in the athlete that experiences repetitive axial loading; increased medial tension and overload syndromes can lead to stress reactions and fractures. This occurs in the developing athlete due to the bone being weaker than the surrounding tendons and ligaments. The medial elbow is a high stress area and is susceptible to many conditions including apophysitis , avulsion fractures and ulnar collateral ligament disruption. Valgus stress can cause injury to the medial elbow which can lead to increased lateral compression, Panner's disease and osteochondral lesions of the capitellum and olecranon. The purpose of this manuscript is to review common elbow disorders in the adolescent population, outline management and highlight important features of rehabilitation. PMID:25840494

    The purpose of this study was to describe four exceptional cases of Salter-Harris type III and IV fractures of the proximal phalanx of the hallux in young high-level gymnasts. All gymnasts underwent the same mechanism of injury of hyperadduction, which indicates a role of the abductor hallucis muscle in the genesis and displacement of these fractures. An open reduction and internal fixation was performed to achieve an anatomical reduction and avoid chronic disability. At 1-year follow-up, all patients had an excellent American Orthopaedic Foot and Ankle Society (AOFAS) score (100 points), and there was no shortening or angulation of the first ray and no evidence of degenerative joint disease on X-ray. Moreover, all the gymnasts had returned to pre-injury levels of sporting activity. To our knowledge, there are no previous studies that address these types of injuries and how they are handled in gymnasts.

    Cutaneous T-cell lymphoma is a type of non-Hodgkin's lymphoma, which is a neoplasm affecting the lymphatic system. Mycosis fungoides is the most common subset of cutaneous T-cell lymphoma and is often treated conservatively. This neoplasm is most common in adults older than 60 years and does not regularly manifest in the toes. A case is reported of a 70-year-old man seen for a nonhealing hallux ulceration leading to amputation. Histopathologic examination revealed a rare transformed CD30(+) high-grade cutaneous T-cell lymphoma. The morbidity of lymphomas is highly dependent on type and grade. Pharmaceutical precision therapies exist that target specific molecular defects or abnormally expressed genes, such as high expression of CD30. This article focuses on treatment protocol and emphasizes the importance of early diagnosis, determination of cell type, and proper referral of atypical dermatologic lesions. PMID:26667508

    A sequel of supracondylar fractures of distal humerus in children is the angular deformity. It is usually more frequent cubitus varus, but there are reported cases of cubitus valgus. The latter may be the cause of the occurrence of a late ulnar nerve neuropathy, which will require treatment. There is controversy as to whether it is possible to successfully treat both problems at the same surgical procedure. This article describes the case of a girl of 11 years old, who has a cubitus valgus deformity secondary to supracondylar fracture of distal humerus of right elbow at the age of seven years, associated with progressive symptoms of ulnar nerve neuropathy. This patient was treated successfully by a single procedure for corrective dome-shaped supracondilar osteotomy associated with subcutaneous anterior transposition of the ulnar nerve through a posterior approach.

At a mean follow-up of seven years, only one revision for sepsis was required in this series of 63 knee replacements. The mean knee score improved from 37 (range 20-45) to 91 (range 65-100) at the last review (p < 0.01) while the function score increased from 29.5 (range 0-50) to 78.7 (range 10-100) (p = 0.01). The mean mechanical axis (HKA) was 14.7 degrees of valgus preoperatively and 1 degrees of valgus postoperatively. After the iliotibial band was automatically released in the approach, only four of 63 knees required additional release for tightness in extension. These results underline the appeal of the lateral approach with the automatic release of the iliotibial band. If required, additional ligament release is recommended step-by-step after bone section to avoid postoperative instability.

    The valgus-impacted (VI) 4-part fractures are a subset of fractures of the proximal humerus with a unique anatomic configuration characterized by a relatively lower incidence of avascular necrosis after operative intervention. We systematically reviewed clinical studies assessing the benefits and harms of least possible fixation techniques (LPFT) for this unique fracture type. Such information would be potentially helpful in developing an evidence-based approach in the management of these complex injuries. We performed analytic searches of PubMed, Embase, Web of Science, Google Scholar and the Cochrane Library, restricting it to the years 1991-2014. Included studies had to describe outcomes and complications after primary osteosynthesis with any type of LPFT apart from plate-screws and intramedullary nailing. Eligibility criteria were also included English language, more than 5 cases, minimum follow up of one year and report of clinical outcome using at least one relevant score (Constant, Neer or ASES). Based on 292 database hits we identified 12 eligible studies including 190 four-part valgus impacted fractures in 188 patients. All eligible studies were case series composed of min 8 to max 45 patients per study. The gender distribution was 60% (112) female and 40% (76) male. The average age of the patients at the time of injury was 54.5 years. In 8/12 studies an open reduction was used for fracture fixation using different surgical techniques including KW, cerclage wires, cannulated screws and osteosutures. Closed reduction and percutaneous fixation was used in 4 studies. Mean follow-up time ranged from 24 to 69 months. A good functional outcome (constant score >80) was reported in 9/12 studies. The most common complication was avascular necrosis of the humeral head with an overall incidence of 11% (range, 0-26.3%). Total avascular necrosis (AVN) was found in 15/188 patients (7.9%) and was more common in percutaneous techniques and partial AVN in 6/188 (3

  1. Medial percutaneous hemi-epiphysiodesis improves the valgus tilt of the femoral head in developmental dysplasia of the hip (DDH) type-II avascular necrosis

    2015-01-01

    Background and purpose Avascular necrosis (AVN) is a major cause of disability after treatment of developmental dysplasia of the hip (DDH), leading to femoral head deformity, acetabular dysplasia, and osteoarthritis in adult life. Type-II AVN is characterized by retarded growth in the lateral aspect of the physis or by premature lateral fusion, which produces a valgus deformity of the head on the neck of the femur. We investigated the effect of medial percutaneous hemi-epiphysiodesis as a novel technique in the treatment of late-diagnosed type-II AVN. Patients and methods 9 patients (11 hips) with a diagnosis of type-II AVN who underwent medial percutaneous hemi-epiphysiodesis after the surgical treatment for DDH were included in the study. 10 patients (12 hips) with the same diagnosis but who did not undergo hemi-epiphysodesis were chosen as a control group. Preoperative and postoperative articulotrochanteric distances, head-shaft angles, CE (center-edge) angles, and physeal inclination angles were measured. The treatment group underwent medial hemi-epiphysodesis at a mean age of 8 years. The mean ages of the treatment group and the control group at final follow-up were 14 and 12 years respectively. The mean duration of follow-up was 5.7 years in the treatment group and 8.3 years in the control group. Results Preoperative articulotrochanteric distance, head-shaft angle, and functional outcome at the final follow-up assessment were similar in the 2 groups. However, preoperative and postoperative CE angles and physeal inclination angles differed significantly in the treatment group (p < 0.05). The final epiphyseal valgus angles were better in the treatment group than in the control group (p = 0.05). The treatment group improved after the operation. Interpretation Medial percutaneous epiphysiodesis performed through a mini-incision under fluoroscopic control is a worthwhile modality in terms of changing the valgus tilt of the femoral head.

    Malaligned knees are predisposed to the development and progression of unicompartmental degenerations because of the excessive load placed on one side of the knee. Therefore, guided growth in skeletally immature patients is recommended. Indication for correction of varus/valgus deformities are based on static weight bearing radiographs. However, the dynamic knee abduction moment during walking showed only a weak correlation to malalignment determined by static radiographs. Therefore, the aim of the study was to measure the effects of guided growth on the normalization of frontal plane knee joint moments during walking. 15 legs of 8 patients (11-15 years) with idiopathic axial varus or valgus malalignment were analyzed. 16 typically developed peers served as controls. Instrumented gait analysis and clinical assessment were performed the day before implantation and explantation of eight-plates. Correlation between static mechanical tibiofemoral axis angle (MAA) and dynamic frontal plane knee joint moments and their change by guided growth were performed. The changes in dynamic knee moment in the frontal plane following guided growth showed high and significant correlation to the changes in static MAA (R=0.97, p<0.001). Contrary to the correlation of the changes, there was no correlation between static and dynamic measures in both sessions. In consequence two patients that had a natural knee moment before treatment showed a more pathological one after treatment. In conclusion, the changes in the dynamic load situation during walking can be predicted from the changes in static alignment. If pre-surgical gait analysis reveals a natural load situation, despite a static varus or valgus deformity, the intervention must be critically discussed.

  3. A numerical simulation approach to studying anterior cruciate ligament strains and internal forces among young recreational women performing valgus inducing stop-jump activities.

    Kar, Julia; Quesada, Peter M

    2012-08-01

    Anterior cruciate ligament (ACL) injuries are commonly incurred by recreational and professional women athletes during non-contact jumping maneuvers in sports like basketball and volleyball, where incidences of ACL injury is more frequent to females compared to males. What remains a numerical challenge is in vivo calculation of ACL strain and internal force. This study investigated effects of increasing stop-jump height on neuromuscular and bio-mechanical properties of knee and ACL, when performed by young female recreational athletes. The underlying hypothesis is increasing stop-jump (platform) height increases knee valgus angles and external moments which also increases ACL strain and internal force. Using numerical analysis tools comprised of Inverse Kinematics, Computed Muscle Control and Forward Dynamics, a novel approach is presented for computing ACL strain and internal force based on (1) knee joint kinematics and (2) optimization of muscle activation, with ACL insertion into musculoskeletal model. Results showed increases in knee valgus external moments and angles with increasing stop-jump height. Increase in stop-jump height from 30 to 50 cm lead to increase in average peak valgus external moment from 40.5 ± 3.2 to 43.2 ± 3.7 Nm which was co-incidental with increase in average peak ACL strain, from 9.3 ± 3.1 to 13.7 ± 1.1%, and average peak ACL internal force, from 1056.1 ± 71.4 to 1165.4 ± 123.8 N for the right side with comparable increases in the left. In effect this study demonstrates a technique for estimating dynamic changes to knee and ACL variables by conducting musculoskeletal simulation on motion analysis data, collected from actual stop-jump tasks performed by young recreational women athletes.

    This study examines the extent to which a group of Scottish adolescents are influenced by negative images of adolescence present in our culture, and investigates their self-image by means of a Q sort. Forty 15- and 16-year-old school students took part in the study, half of whom were female. Half of the sample were staying on at school to take higher examinations, the other half being school leavers. Eleven factors emerged from the analysis, the first six of which met the criterion that distinguishes common factors. Participants defining common factors were re-interviewed, and their responses to factor interpretations noted. Little evidence was found to suggest that adolescents are influenced by newspaper images. Some descriptions hint at conflict, while others do not. If the results of the present study were to be replicated, a more pluralistic view of adolescence may be required.

    Purpose The purpose of this paper is to outline notable alterations occurring in the adolescent brain, and consider potential ramifications of these developmental transformations for public policy and programs involving adolescents. Methods Developmental changes in the adolescent brain obtained from human imaging work are reviewed, along with results of basic science studies. Results Adolescent brain transformations include both progressive and regressive changes that are regionally specific and serve to refine brain functional connectivity. Along with still maturing inhibitory control systems that can be overcome under emotional circumstances, the adolescent brain is associated with sometimes elevated activation of reward-relevant brain regions, whereas sensitivity to aversive stimuli may be attenuated. At this time, the developmental shift from greater brain plasticity early in life to the relative stability of the mature brain is still tilted more towards plasticity than seen in adulthood, perhaps providing an opportunity for some experience-influenced sculpting of the adolescent brain. Conclusions Normal developmental transformations in brain reward/aversive systems, areas critical for inhibitory control, and regions activated by emotional, exciting and stressful stimuli may promote some normative degree of adolescent risk-taking. These findings have a number of potential implications for public policies and programs focused on adolescent health and well-being. PMID:23332574

  9. Greater Hip Extension but Not Hip Abduction Explosive Strength Is Associated With Lesser Hip Adduction and Knee Valgus Motion During a Single-Leg Jump-Cut

    PubMed Central

    Cronin, Baker; Johnson, Samuel T.; Chang, Eunwook; Pollard, Christine D.; Norcross, Marc F.

    2016-01-01

    Background: The relationships between hip abductor and extensor strength and frontal plane hip and knee motions that are associated with anterior cruciate ligament injury risk are equivocal. However, previous research on these relationships has evaluated relatively low-level movement tasks and peak torque rather than a time-critical strength measure such as the rate of torque development (RTD). Hypothesis: Females with greater hip abduction and extension RTD would exhibit lesser frontal plane hip and knee motion during a single-leg jump-cutting task. Study Design: Descriptive laboratory study. Methods: Forty recreationally active females performed maximal isometric contractions and single-leg jump-cuts. From recorded torque data, hip extension and abduction RTD was calculated from torque onset to 200 ms after onset. Three-dimensional motion analysis was used to quantify frontal plane hip and knee kinematics during the movement task. For each RTD measure, jump-cut biomechanics were compared between participants in the highest (high) and lowest (low) RTD tertiles. Results: No differences in frontal plane hip and knee kinematics were identified between high and low hip abduction RTD groups. However, those in the high hip extension RTD group exhibited lower hip adduction (high, 3.8° ± 3.0°; low, 6.5° ± 3.0°; P = .019) and knee valgus (high, –2.5° ± 2.3°; low, –4.4° ± 3.2°; P = .046) displacements during the jump-cut. Conclusion: In movements such as cutting that are performed with the hip in a relatively abducted and flexed position, the ability of the gluteus medius to control hip adduction may be compromised. However, the gluteus maximus, functioning as a hip abductor, may take on a pivotal role in controlling hip adduction and knee valgus motion during these types of tasks. Clinical Relevance: Training with a specific emphasis on increasing explosive strength of the hip extensors may be a means through which to improve frontal plane hip and knee

    The dramatic improvements achieved in the control of vaccine-preventable diseases in children have only been shared partially by adolescents and young adults, as today several million adolescents are not receiving the full complement of vaccines recommended by the Advisory Committee on Immunization Practices (ACIP). This article discusses the reasons for this problem and the tools to bridge this gap. In particular, medical societies and the Centers for Disease Control and Prevention (CDC) recommend a close assessment of the adolescentís immunization status between 11 and 12 years of age, inclusion of school immunization, and providing missing immunizations at any opportunity. The article also addresses other vaccines recommended for groups of adolescents with special needs, reporting information, and provides an update on the vaccines of the future.

  12. Adolescent sexuality.

    Grant, L M; Demetriou, E

    1988-12-01

    The consequences of adolescent sexual behavior are an enormous burden both for the adolescent and society. The problem is not that teens are sexually active but rather that they have little preparation and guidance in developing responsible sexual behavior. Developmentally, adolescents reach physical maturity before they are cognitively able to appreciate the consequences of their behavior. A teenager's primary source of information regarding sexuality is his or her peer group, all of whom are experiencing and reinforcing the same behaviors. The family, the major socializer of other behaviors, is not as powerful a force in shaping responsible sexual behavior because of parental discomfort with sex education and sexual discussions. This is the result of a social milieu in which sex is frequently portrayed but rarely linked with responsible behavior or accurate, nonjudgmental information. The pediatric practitioner is in an ideal position to intervene in these dynamics. In the office, the practitioner can provide accurate sexual information to both parents and adolescents, support parental-child communication on sexual issues, and provide appropriate services or referral. In the community, the practitioner can advocate for school-based sex education as well as act as an information resource. Finally, the practitioner can advocate for the health care needs for adolescents on a national level, supporting legislation that provides adolescents with information and access to services necessary to make responsible sexual decisions.

    The purpose of this study was to investigate the phenomenon of loneliness in delinquent adolescents with regard to types of delinquency offenses committed, demographic characteristics, and personality characteristics in the areas of interpersonal needs for inclusion, control, and affection. The types of delinquency offenses were categorized as burglary, runaway, drugs, assault, and incorrigible. The demographic variables examined were age, sex, race, family rank or birth order, family structure in terms of parental presence, family income level, religion, and geographic locale. A sample of 98 adolescents was obtained from juvenile detention facilities in three metropolitan areas in the United States. Subjects ranged in age from 12 to 18. Subjects were asked to complete the Loneliness Questionnaire as a self-reported measure of loneliness. Subjects also provided information about themselves relative to demographic characteristics and completed the FIRO-B Questionnaire, which measured interpersonal needs for inclusion, control, and affection. The results revealed no significant differences with regard to any of the demographic variables when the effect of each was considered alone. However, there was a significant effect on loneliness by income when considered jointly with other demographic variables. Adolescents from the middle income group expressed more loneliness than those from the upper and lower income groups. No significant differences were observed with regard to personality characteristics related to interpersonal needs for inclusion and affection, but delinquent adolescents with medium to high needs for control indicated significantly more feelings of loneliness than delinquent adolescents with low needs for control.

    Young people in their teens constitute the largest age group in the world, in a special stage recognized across the globe as the link in the life cycle between childhood and adulthood. Longitudinal studies in both developed and developing countries and better measurements of adolescent behavior are producing new insights. The physical and psychosocial changes that occur during puberty make manifest generational and early-childhood risks to development, in the form of individual differences in aspects such as growth, educational attainment, self-esteem, peer influences, and closeness to family. They also anticipate threats to adult health and well-being. Multidisciplinary approaches, especially links between the biological and the social sciences, as well as studies of socioeconomic and cultural diversity and determinants of positive outcomes, are needed to advance knowledge about this stage of development.

    Olukoya, A A; Kaya, A; Ferguson, B J; AbouZahr, C

    2001-11-01

    Every year, an estimated 2.0-4.4 million adolescents resort to abortion. In comparison with adults, adolescents are more likely to delay the abortion, resort to unskilled persons to perform it, use dangerous methods and present late when complications arise. Adolescents are also more likely to experience complications. Consequently, adolescents seeking abortion or presenting with complications of abortion should be considered as a medical emergency. Issues requiring special attention in the management of abortion complications in adolescents are identified. Approaches to adolescent abortion should involve all levels of the health care system, as well as the community, and should include not only management of the consequences of unsafe abortion, but also post-abortion contraception and counseling. Prevention of unwanted pregnancy by providing information on sexuality, ensuring that reproductive health services are adolescent-friendly, creating a supportive environment, building young people's social and decision-making skills, and offering counseling in times of crisis are highlighted.

Pediatricians' long-term relationships with adolescents and families allow them to help promote healthy sexual decision-making, including abstinence and contraceptive use. Additionally, medical indications for contraception, such as acne, dysmenorrhea, and heavy menstrual bleeding, are frequently uncovered during adolescent visits. This technical report provides an evidence base for the accompanying policy statement and addresses key aspects of adolescent contraceptive use, including the following: (1) sexual history taking, confidentiality, and counseling; (2) adolescent data on the use and side effects of newer contraceptive methods; (3) new data on older contraceptive methods; and (4) evidence supporting the use of contraceptives in adolescent patients with complex medical conditions.

    2014-10-01

    Contraception is a pillar in reducing adolescent pregnancy rates. The American Academy of Pediatrics recommends that pediatricians develop a working knowledge of contraception to help adolescents reduce risks of and negative health consequences related to unintended pregnancy. Over the past 10 years, a number of new contraceptive methods have become available to adolescents, newer guidance has been issued on existing contraceptive methods, and the evidence base for contraception for special populations (adolescents who have disabilities, are obese, are recipients of solid organ transplants, or are HIV infected) has expanded. The Academy has addressed contraception since 1980, and this policy statement updates the 2007 statement on contraception and adolescents. It provides the pediatrician with a description and rationale for best practices in counseling and prescribing contraception for adolescents. It is supported by an accompanying technical report.

    2012-04-01

    Adolescent pregnancy remains a public health issue with significant medical, emotional, and societal consequences for the adolescent mother, her child, and her family. Teenage pregnancies are at higher risk of many adverse outcomes, including preterm delivery, low birth weight, and neonatal and infant mortality. Teen pregnancy and motherhood may have detrimental effects on the teen mother and her child; antenatal and postpartum care need to be adapted to meet the special needs of pregnant adolescents because standard obstetrical environments may not do so. This comprehensive review of adolescent pregnancy will highlight global statistics, factors contributing to adolescent pregnancy, social implications of adolescent pregnancy, obstetrical and neonatal outcomes, and the importance of multidisciplinary antenatal and postnatal care.

    Adolescents have high rates of unintended pregnancy and face unique reproductive health challenges. Providing confidential contraceptive services to adolescents is important in reducing the rate of unintended pregnancy. Long-acting contraception such as the intrauterine device and contraceptive implant are recommended as first-line contraceptives for adolescents because they are highly effective with few side effects. The use of barrier methods to prevent sexually transmitted infections should be encouraged. Adolescents have limited knowledge of reproductive health and contraceptive options, and their sources of information are often unreliable. Access to contraception is available through a variety of resources that continue to expand.

    1992-12-01

    The proportion of women aged 15-19 in Colombia who are mothers declined from 14% in 1985 to 10% in 1990, but the actual number of cases increased due to population growth. Some 1,780,000 adolescents who have had children or are pregnant require family planning services. An additional, unknown number of adolescent pregnancies are terminated by abortion. It is estimated that 95% of adolescent pregnancies diagnosed or followed by PROFAMILIA's center for young people were unwanted. Reasons for making family planning services available to adolescents include the ever young age at initiation of sexual activity, the very low rates of contraceptive usage among sexually active adolescents, the lack of information of adolescents concerning reproduction and contraception, and their fear and guilt surrounding their sexual activity and contraceptive usage. Obstetrical services appear reluctant to furnish adolescent mothers with information on contraception, and the pharmacists and their employees who provide such information may not be aware of contraindications for this age group or whether adolescents are adequately instructed in use of the method. The rising age at marriage increases the span of time that adolescents are at risk of unwanted pregnancy. Adolescents who are well informed about sexuality and contraception and trained in decision making, self-esteem, and responsible parenthood are likely to postpone sexual activity. Information on contraception and family planning services needs to be made available to adolescents in a way that will actually motivate use. Information on sex and contraception should be made available at puberty and should include the form of use, contraindications, and advantages and disadvantages of all methods appropriate to adolescents. Orientation and assistance in selecting the best method should be individually tailored and should be provided in schools or other places accessible to young people, in a language they can understand.

    2013-01-01

    Objectives To examine the efficacy of self-report and parental report of adolescent sleep problems and compare these findings to the incidence of adolescents who fulfill clinical criteria for a sleep problem. Sleep and daytime functioning factors that predict adolescents’ self-identification of a sleep problem will also be examined. Method 308 adolescents (aged 13–17 years) from eight socioeconomically diverse South Australian high schools participated in this study. Participants completed a survey battery during class time, followed by a 7-day Sleep Diary and the Flinders Fatigue Scale completed on the final day of the study. Parents completed a Sleep, Medical, Education and Family History Survey. Results The percentage of adolescents fulfilling one or more of the criteria for a sleep problem was inordinately high at 66%. Adolescent self-reporting a sleep problem was significantly lower than the adolescents who had one or more of the clinical criteria for a sleep problem (23.1% vs. 66.6%; χ2 = 17.46, p<.001). Parental report of their adolescent having a sleep problem was significantly lower than adolescent self-report (14.3% vs. 21.1%, p<.001). Adolescents who reported unrefreshing sleep were 4.81 times more likely to report a sleep problem. For every hour that bedtime was delayed, the odds of self-reporting a sleep problem increased by 1.91 times, while each additional 10 minutes taken to fall asleep increased the odds 1.40 times. Conclusion While many adolescents were found to have sleep patterns indicative of a sleep problem, only a third of this number self-identify having a sleep problem, while only a sixth of this number are indicated by parental report. This study highlights important features to target in future sleep education and intervention strategies for both adolescents and parents. PMID:24086501

    22% of the population of Peru, or 4.25 million individuals, is between the ages of 11 and 19 years. A survey was performed on a sample of 6,000 adolescents living in Lima, Cajamarca, Huarez, and Supe. Surveys were performed in a variety of locations, including school classrooms, maternity wards, schools, and work places. The questionnaire was constructed based on a format that had been tested in Nigeria; questions dealt with socioeconomic background, sex behavior, contraceptive behavior, pregnancy history, and health practices and knowledge. 60% of the adolescents were women and 40% were men. 41% had had at least 1 sexual experience; among 18-year-olds, this % rose to 55. Only 10% were in stable union. Married adolescents tended to have begun sexual relations sooner in life. Early sexual relations were more common among men than among women, and more common among non-religious adolescents than among Catholics. Fewer than 12% of the adolescents had at 1 time used contraceptives. Contraceptive use was more prevalent among adolescents from wealthier socioeconomic groups, and more prevalent in Lima than in other regions surveyed. Of adolescents using contraceptives, 38% used condoms, 24% used oral contraceptives, and 15% used rhythm methods. Most adolescents who did not use contraceptives failed to do so because of lack of knowledge. Almost 1/4 of the young women had had a pregnancy. 18.5 of these had abortions, usually in a hospital. The importance of supporting educational prevention programs is underlined.

    We present in some detail what constitutes normal behavior, or mental health, among teenagers. Our data are based on the results of a specially devised psychological questionnaire by one of us (D.O.). This questionnaire has been shown to reliably distinguish mentally healthy from psychiatrically disturbed populations. Results are presented across three decades (1960s, 1970s, and 1980s), across genders, and across the high school years. A conceptual framework is presented to help the clinician working with adolescents to understand the fluctuation in psychopathology among youth. Adolescent density in the total population is shown to be a significant factor in determining the rate of disturbance among teenagers. Our research findings demonstrate that the rate of behavioral disturbance among adolescents is the same as in other parts of the life cycle. The clinician working with adolescents tends to underestimate the severity of adolescent problems because of the near-universal belief that all adolescents undergo "adolescent turmoil." We have found that adolescents who are experiencing turmoil need professional help.

  16. Smoking and adolescent health

    PubMed Central

    2011-01-01

    With the Westernization and opening of our society, adolescents' smoking is increasing and being popularized. Many adolescents start smoking at an early age out of curiosity and venturesomeness, and earlier start of smoking makes it more difficult to quit smoking. Adolescents' habitual smoking not only becomes a gateway to all kinds of substance abuse but also causes various health problems including upper respiratory infection, immature lung development, reduced maximum vital capacity, and lung cancer. Therefore, it is quite important to prevent adolescents from smoking. The lowering of adolescents' smoking rate cannot be achieved only through social restrictions such as stereotyped education on the harms of smoking and ID checking. In order to lower adolescents' smoking rate substantially, each area of society should develop standardized programs and make related efforts. As adolescents' smoking is highly influenced by home environment or school life, it is necessary to make efforts in effective education and social reinforcement in school, to establish related norms, and to execute preventive education using peer groups. When these efforts are spread throughout society in cooperation with homes and communities, they will be helpful to protect adolescents' health and improve their quality of life. PMID:22232621

    Concerns about the adequate assessment and treatment of adolescent depression have been in the forefront of pediatric mental health literature in the recent past. While quantitative studies have provided valuable information, the voice of the adolescent has been lacking in the development of theory and treatment of this prevalent disorder. Using approach, a metasynthesis of six qualitative studies was conducted. This process revealed six themes that outline the course of adolescents who struggle with depression: (a) beyond the blues, (b) spiraling down and within, (c) breaking points, (d) seeing and being seen, (e) seeking solutions, and (f) taking control. Knowledge of the experience of adolescent depression will aid practitioners in recognition and early intervention for the increasing number of adolescents suffering with depression, as well as guide educational initiatives to provide needed information on the symptoms of depression and available resources for getting help.

    2011-01-01

    Researchers are increasingly interested in identifying specific aspects of adolescents' lives that are positively or adversely affected by their place of residence. This body of work suggests that it is important to consider neighborhoods when examining their 1) engagement in risk-related behaviors; 2) educational outcomes; 3) physical and mental health; and 4) their integration within social institutions. To date, however, no existing work has simultaneously considered the range of outcomes in which neighborhoods are believed to be important within and across these four domains. Using data from the National Longitudinal Study of Adolescent Health, we examine the extent to which neighborhoods influence adolescent outcomes across 34 characteristics nested within these four areas. The findings suggest that for adolescents, residential area is equally important in terms of risk behaviors, educational outcomes, and their integration within their families, schools, and churches. However, we find no evidence that neighborhoods are associated with adolescents' physical health or emotional well-being. PMID:21984874

    2012-08-01

    Onset of bulimia nervosa (BN) typically occurs in adolescence and is frequently accompanied by medical and psychiatric sequelae that may have detrimental effects on adolescent development. Potentially serious medical consequences and high comorbid rates of mood disorders and suicidality underscore the need for early recognition and effective treatments. Research among adolescents with BN has lagged behind that of adults, although evidence is accumulating to support the efficacy of family-based interventions and cognitive behavioral treatments that are adapted for use with adolescent populations. The aim of the current article is to provide an overview of recent research on epidemiology, risk factors, diagnostic issues, and treatment interventions focusing on adolescent BN, and to highlight areas for future research.

    Rosenstein, D S; Horowitz, H A

    1996-04-01

    The relationships among attachment classification, psychopathology, and personality traits were examined in a group of 60 psychiatrically hospitalized adolescents. The concordance of attachment classification was examined in 27 adolescent-mother pairs. Both adolescent and maternal attachment status were overwhelmingly insecure and were highly concordant. Adolescents showing a dismissing attachment organization were more likely to have a conduct or substance abuse disorder, narcissistic or antisocial personality disorder, and self-reported narcissistic, antisocial, and paranoid personality traits. Adolescents showing a preoccupied attachment organization were more likely to have an affective disorder, obsessive-compulsive, histrionic, borderline or schizotypal personality disorder, and self-reported avoidant, anxious, and dysthymic personality traits. The results support a model of development of psychopathology based partially on relational experiences with parents.

    Androgenetic alopecia (AGA), or hereditary hair thinning, is a common and unwelcome cause of hair loss in men and women. AGA also occurs in adolescents, though its prevalence in this younger population is not known. Physical appearance is extremely important to most adolescents, and early onset of hair loss can have a definite negative effect on self-image and self-esteem. Minoxidil topical solution is widely used by adults for hair loss, but its use by adolescents has not been systematically evaluated. This article provides an overview of AGA and presents new information on the prevalence and age at onset of hereditary hair thinning in adolescents. In addition, data are presented on the efficacy and proper use of minoxidil topical solution in adolescent boys and girls. PMID:12635889

The present investigation tested a model whereby parent-adolescent negative emotionality traits, adolescent conflict, and adoption status contribute to adolescent externalizing behaviors.…

  4. Adolescent and Parental Contributions to Parent-Adolescent Hostility Across Early Adolescence.

    2016-04-01

    Early adolescence is characterized by increases in parent-adolescent hostility, yet little is known about what predicts these changes. Utilizing a fairly large sample (N = 416, 51 % girls, 91 % European American), this study examined the conjoint and unique influences of adolescent social anxiety symptoms and parental intrusiveness on changes in parent-adolescent hostility across early adolescence. Higher mother and father intrusiveness were associated with increased mother- and father-adolescent hostility. An examination of reciprocal effects revealed that mother- and father-adolescent hostility predicted increased mother and father intrusiveness. Significant associations were not substantiated for adolescent social anxiety symptoms. These findings suggest that intrusive parenting has important implications for subsequent parent-adolescent interactions and that similar patterns may characterize some aspects of mother- and father-adolescent relationships.

  5. Teaching adolescents about adolescence: experiences from an interdisciplinary adolescent health course.

    As abstract reasoning increases in complexity, adolescents may face dissonance between new thoughts and prior beliefs. Students in the health professions may be forced to resolve these dissonances in order to execute their professional responsibilities. In developing an undergraduate interdisciplinary course on adolescent health, the authors anticipated challenges in teaching adolescents about adolescence. Over the course of the semester, the anticipated challenges became reality. The author discusses pertinent developmental theories and their application in facilitating late adolescent identity formation and professional role development.

    Adolescents are the future adults of the world. While adolescence is typically regarded as a period of life relatively free from health problems, adolescents are actually in need of the attention of health professionals and health services, especially with regard to sexual health. A trend of decreasing age at menarche and increasing age at marriage presents adolescents with a substantial number of years in which they will experiment with their developing reproductive organs and sexuality. Substantial psychological and physical change takes place during this period. Inconsistent and suboptimal users of contraception, youths are at high risk for reproductive health problems and sexually transmitted diseases. Substance abuse, unintentional and intentional injuries and their sequelae, academic underachievement and illiteracy, and obesity may also be problematic for adolescents. Adolescents are, however, most damaged by internalized and externalized homophobia. The authors point out that adolescents may be persuaded to learn and change their behaviors more readily than adults. Appropriate messages could be conveyed through targeted information, education, and communication strategies to complement medical and health care services which are available, accessible, and acceptable.

    Graffiti has been studied for many years from many viewpoints. They have been used to explain accounts of people, styles of life, and assumed relationships. The present paper reports an attempt to analyze graffiti as outward manifestations of adolescent personality. Results suggested that different forms of graffiti could be interpreted from five characterizations of early adolescent personality: sexual maturity, self-identity, idealism, iconoclasm, and rebelliousness. Significant differences were found between boys and girls in numbers of inscriptions for each category. Further, the graffiti were analyzed in relation to early adolescent stages of development.

    This study is concerned with adolescent attitudes to authority. In particular the investigation focuses on notions of the ideal authority figure, attitudes to the sorts of conflicts experienced at home and in school, and on the types of resolutions to conflicts preferred by young people. Subjects were 43 adolescents from working class areas in outer London boroughs, all of whom were given a semistructured interview. Results indicated important differences in the amount of control required at home and in the school, and showed adolescents of 14 and 15 to have relatively little need for autonomy but a very considerable need for support from parents and teachers.

    Adolescent basketball players can be viewed in two ways, as a unique population requiring special attention for their unique problems or as a similar group sharing the same problems as their adult counterparts. Attention should be paid to issues related to adolescence in general including changes in body size, growth of the musculoskeletal system, and hormonal changes that contribute to changes in behavior, emotions, and maturity. Attention to the particular needs of the adolescent basketball player may help prevent problems or lead to early recognition and intervention.

    Theunissen, L

    1986-11-01

    The majority of books, studies, and publications on adolescence are written by adults, whose frequent focus on unbridled adolescent sexuality, adolescents in crisis, or immature adolescents does not seem to correspond to the self-image of adolescents. All authors agree that adolescence is the period between childhood and adulthood beginning at puberty, but opinions differ as to the termination of adolescence and entrance into adulthood. The most significant consensus about adolescence is its tendency to become prolonged. The majority of authors regard adolescence as a preparation for adult life and hence as a natural phase necessary and indispensable to human existence. Ethnographic studies of societies that do not acknowledge adolescence demonstrate, however, that it is not a natural phase. It is also evident that comparatively few roles in modern society require lengthy periods of preparation such as adolescence. It is therefore difficult to regard adolescence as a time of preparation for adult life. From a historic perspective, adolescence emerged with the socioeconomic transformations of industrialization. Mechanization and automation excluded numerous types of workers, especially young workers, from the labor force. Adolescence represents marginalization of young people in response to socioeconomic exigencies rather than a period of preparation for a better adult life. The marginalization is internalized in the consciousness of adults and youth alike and in their hierarchical relations. The marginalization of young people is expressed in the domain of sexuality by the fact that, although physiologically mature, adolescents are not viewed as psychologically mature enough to have children. Adolescents have sexual relations at increasingly young ages, but unlike adults they are not permitted by society the choice of having a child. Contraception, an option for adults, becomes obligatory for sexually active adolescents. The refusal of contraception or failure to

    According to the Canadian Association of Family Planning 85% of adolescents are unprotected at their 1st intercourse, and 16% become pregnant; only 20% of those having a regular sex life use contraception. Women below 20 contributed to 17% of births in 1976 in Canada; in the same year 41.5% of all new mothers were unmarried, and only 27.5% of new fathers accepted responsibility for their paternity. These figures give an idea of the extent of the problem of unwanted pregnancy among adolescents, a problem shared by all Western countries. The adolescent mother is too young to know what she wants, not to mention to accept responsibility for the caring of an infant. Risk of maternal mortality is twice as great among teenage mothers, and so is risk of infant death, mostly due to prematurity. Nurses can play a very important role in helping adolescent mothers, and they must never project their moral values on their young patients.

    Adolescent health is not a priority to public health services. The physical, psychological and social changes lived by youngsters expose these individuals to several health risks and events that are determinant to their actual and future health status. The main health problems in adolescents are infectious respiratory and gastrointestinal diseases but traumatisms are very important in males. Female adolescents demand services related to their reproductive life and link to early and not desired pregnancies. Another important health problem is overweight and obesity in both sexes. The main causes of death in this age group are malignant tumors, specially leukemias, and accidents. We do not have information related to health risks like addictions and mental health. Data show how important adolescents health should be to the public health sector specially because it will be more easy to tackle their health risks and negative health life-styles at this age than further in their lives.

    Adolescents often feel like sexual beings because of the physical and psychological changes produced by their hormones. Adolescents are sometimes disturbed by their newly occurring sexual fantasies and by lack of understanding from their parents of the changes they are experiencing. These factors together with social pressures of various kinds occasionally make the adolescent forget that decisions about how to behave sexually should be made by the individual, not by others. Adolescents should be able to evaluate personal relationships for their positive or destructive qualities. Decisions by adolescents about their sexual behavior and about when a personal relationship should become a sexual relationship are made more difficult by the conflicting social, group, and interpersonal pressures they face. In a good sexual relationship as in a good friendship, the 2 persons feel confident and behave honestly with each other. Neither dominates the other, and the relationship is pleasurable rather than negative for both. According to research, the 1st sexual relations of an adolescent often occur with an adult. Sex is usually unpremeditated and unplanned. Many adolescents are disappointed in their 1st sexual experiences, which may have occurred in unfavorable circumstances. The combination of inadequate sex education and knowledge of what to expect and unrealistically high expectations from movies or stories probably are principal causes of disappointment. Adolescents in the process of maturing from childhood into adulthood are not completely prepared psychologically or socioculturally for parenthood. In Mexico, 75% of 1st unions are believed to begin before the woman is 20 years old. Most adolescents who become pregnant do not use contraception. In 1976, only 16% of new family planning acceptors were believed to be 15-19 years old. The proportion of births to mothers under 18 was estimated to have increased from 3.1% in 1968-70 to 10% in 1976. Adolescent pregnancies

    PubMed

    Senderowitz, J; Paxman, J M

    1985-04-01

    There is growing concern over the adverse health, social, economic, and demographic effects of adolescent fertility. Morbidity and mortality rates ar significantly higher for teenage mothers and their infants, and early initiation of childbearing generally means truncated education, lower future family income, and larger completed family size. Adolescent fertility rates, which largely reflect marriage patterns, range from 4/1000 in Mauritania; in sub-Saharan Africa, virtually all rates are over 100. In most countries, adolescent fertility rates are declining due to rising age at marriage, increased educational and economic opportunities for young women, changes in social customs, increased use of contraception, and access to abortion. However, even if fertility rates were to decline dramatically among adolescent women in developing countries, their sheer numbers imply that their fertility will have a major impact on world population growth in the years ahead. The number of women in the world ages 15-19 years is expected to increase from 245 million in 1985 to over 320 million in the years 2020; 82% of these women live in developing countries. As a result of more and earlier premarital sexual activity, fostered by the lengthening gap between puberty and marriage, diminished parental and social controls, and increasing peer and media pressure to be sexually active, abortion and out-of-wedlock childbearing are increasing among teenagers in many developed and rapidly urbanizing developing countries. Laws and policies regarding sex education in the schools and access to family planning services by adolescents can either inhibit or support efforts to reduce adolescent fertility. Since contraceptive use is often sporadic and ineffective among adolescents, family planning services are crucial. Such programs should aim to reduce adolescents' dependence on abortion through preventive measures and increase awareness of the benefits of delayed sexual activity. Similarly, sex

  3. Iron nutrition in adolescence.

    PubMed

    Mesías, Marta; Seiquer, Isabel; Navarro, M Pilar

    2013-01-01

    Adolescence is an important period of nutritional vulnerability due to increased dietary requirements for growth and development. Iron needs are elevated as a result of intensive growth and muscular development, which implies an increase in blood volume; thus, it is extremely important for the adolescent's iron requirements to be met. Diet, therefore, must provide enough iron and, moreover, nutrients producing adequate iron bioavailability to favor element utilization and thus be sufficient for needs at this stage of life. Currently, many adolescents consume monotonous and unbalanced diets which may limit mineral intake and/or bioavailability, leading to iron deficiency and, consequently, to ferropenic anemia, a nutritional deficit of worldwide prevalence. Iron deficiency, apart from provoking important physiological repercussions, can adversely affect adolescents' cognitive ability and behavior. Accordingly, promoting the consumption of a varied, adjusted, and balanced diet by adolescents will facilitate iron utilization, benefiting their health both at present and in adulthood. This review discusses how physiological changes during adolescence can cause iron requirements to increase. Consequently, it is important that diet should contribute an appropriate amount of this mineral and, moreover, with an adequate bioavailability to satisfy needs during this special period of life.

  4. Addiction in adolescents.

    PubMed Central

    Morrison, M A

    1990-01-01

    Some symptoms seen in adolescents with the disease of chemical dependence are similar to those seen in adults. Because of their age, lack of personality development, dependent family role, immaturity, and acting out of age-related behavioral tendencies, however, symptoms specific to this population occur. These may become exacerbated and telescope--intensify and shorten--the progression of the disease. A plan to solve the problem of adolescent chemical dependence must focus on education, demonstration, cooperation, prevention, intervention, habilitation, treatment, and recovery. The phenomenon of denial in a chemically dependent adolescent yields a more complex delusional system that dictates age-specific intervention approaches. Habilitation is necessary for successful adolescent treatment and recovery because what is needed is an initial process of learning, not relearning or rehabilitation. If specific adolescent issues are addressed through comprehensive, multimodality treatment approaches, then treatment and recovery outcomes for chemically dependent adolescents and their families are substantially improved. Primary care physicians must be alert to the possibility of drug use in their young patients and aware of treatment options. PMID:2349798

  7. The adolescent and contraception.

    PubMed

    Bonar, R W; Mcculla, D

    1981-08-01

    Coital activity is often initiated during adolescence, and adolescents, like many adults, do not behave in purely rational ways and frequently fail to protect themselves against undesired pregnancy. Public attention is focused on adolescent pregnancies because of their increasing number and because the consequences are usually catastrophic. Unplanned pregnancies can have physical, psychosocial, and prenatal effects. It is important from both the individual and societal perspective that high priority be given to the task of preventing adolescent pregnancy. The health care provider, to gain the trust of the adolescent, must be open, honest, and willing to consider the young person's feelings and motivations. In addition to historical data and physical examination, the choice of a contraceptive method is based on individual preferences involving personal, familial, religious, and societal beliefs as well as sexual practice. A decision involving birth control for the adolescent can be complicated by parental influence and involvement. The teenage years are frequently a time of embarrassment about the physical maturation and biological functioning of the body. Birth control methods which require a person to touch himself/herself or to be used at the time of sexual intercourse may be unacceptable to the teenager. Fertility awareness techniques, such as basal body temperature, rhythm, and cervical mucus methods are inexpensive but call for a high degree of personal motivation. The use of a diaphragm requires an office visit and a pelvic examination for fitting and prescription. Contraceptive foam, suppositories, and condoms can be easily obtained over-the-counter for a minimal cost, and a moderate degree of personal motivation is needed for their effective use. Though effective, abortions should not be recommended indiscriminately. Permanent contraceptive methods are not recommended for the adolescent. The IUD and oral contraceptives (OCs) are recommended for adolescents

    The purpose of this study was to analyze changes in early adolescents' intimate behaviors and the initiation of sexual intercourse over a one-year time period. The changes are interpreted within the context of recent progress in understanding the development of early adolescents. Public school students in sixth and ninth grades of selected schools in a midwestern industrial city were studied in two waves of data collection. A total of 106 students provided data for the second year, allowing comparisons of their Time 2 with their Time 1 responses. Five of eight intimate behaviors studied increased in frequency during the year. Also, the adolescents' perceived benefits of having sexual intercourse increased and perceived costs decreased during the follow-up year. Increases in the frequency of intimate behaviors but not changes in their perceptions of the benefits and costs predicted whether or not students had initiated sexual intercourse during the follow-up period. These findings support current understanding of early adolescence as a time of incremental learning about intimacy and about sexual relationships. The findings suggest that preventing early sexual intercourse may require understanding the specific behavioral competencies related to healthful development of intimacy. Pediatric nurses can be leaders in providing the necessary counseling and education to young adolescents, their families, and their communities.

    Pediatric obesity has increased from a relatively uncommon problem to one of the most important public health problems facing children today. Typical "adult" diseases, such as type 2 diabetes mellitus, hypertension, and dyslipidemia, have become increasingly prevalent in the pediatric population. The earlier presentation of these comorbidities will have a significant impact for the future because this population of children will require more medical resources at an earlier age and will have a significantly decreased life expectancy. The significant morbidity of obesity in the pediatric population has led to consideration of more aggressive treatment protocols for obesity in children, including the introduction of surgical management at an earlier age. Surgery for obesity in adolescents has particular risks and benefits that must be accounted for when considering this approach. The unique psychological and emotional needs of adolescent patients make the patient selection process and perioperative management substantially different from those of adult patients. Initial outcomes of bariatric surgery in adolescents are comparable to those seen in adults in the short term. However, the long-term effects of these procedures on the adolescent population are not known. This review discusses the epidemiology of pediatric obesity, the indications for operative therapy in adolescent patients, the common surgical procedures used for weight loss, the reported outcomes of these procedures, and the importance of multidisciplinary management for this unique patient population.

  10. Psychopharmacology in adolescent medicine.

    Psychopharmacology is a challenge for health care providers treating adolescents. A detailed and accurate assessment, including developmental issues relevant to adolescence in general and to the individual adolescent, guides clinicians in formulating thoughtful and effective treatment plans to meet the needs of each patient. Parents play an important role in providing family history regarding psychiatric diagnoses and the response to various drugs, in making decisions to initiate medication and to change a medication regimen, and in monitoring an adolescent's adherence to a prescribed regimen. The role of parents is especially important for younger patients. Following the biopsychosocial model, rarely should psychopharmacologic agents be used as the sole means to treat a psychiatric condition in adolescents. Pharmacologic agents described in this article are tools that have their effect in the biological domain of central neurotransmitters, but psychosocial interventions addressing the emotional and behavioral issues that are the indications for such medication are generally also required. The development of newer medications holds promise for more effective treatment of target symptoms with minimal side effects. PMID:16473299

    Family dynamics around the adolescent Adolescence modifies the family dynamics around the adolescent because adolescence comprises an unavoidable process of psychological separation between the subject and the parents of his childhood. On the adolescent side, the relations with his parents show a newer claim of recognition. On the parents' side, the mourning deals with several topics. The outcome of the crisis depends on the inner family control of anxiety and on the degree of differentiation of its members. Parents, grandparents and siblings have an important role to play in those transformations. PMID:16097251

    Sexually transmitted diseases (STDs) are a serious health problem for adolescents, occurring in an estimated one-quarter of sexually active teen-agers. Many of the health problems--including STDs--result from specific risk-taking behaviors. Determinants of STD risks among adolescents include behavioral, psychological, social, biological, institutional factors. Education is an important component in STD control in adolescents. The goal of education is to increase adolescent self-efficiency in practicing STD prevention and risk-reduction. A comprehensive approach including quality, theory-based education, accessible and effective health clinics, and improved social and economic conditions has the most promise of controlling STDs in adolescents.

    Sickle cell disease adds relevant problems to the physical, emotional and social changes that normally occur during adolescence. Specific physical characteristics and complications of the disease can hinder the social and emotional adjustment of the affected teenagers. The cooperation between the physician and the parents is essential in order to assist the teenager to the difficulties of this critical phase of adolescence. Recommendations are best offered in the form of education of the adolescent about the disease, education of the family and the school about the needs of the adolescent, and the preparation of the adolescent for the transition to the adult life and adult medical care.

    Each year thousands of adolescent girls and young women in South Africa (SA) become pregnant and many die from complications related to pregnancy and childbirth. Although women of all ages are susceptible, girls<15 years of age are five times as likely, and those aged 15-19 years twice as likely, to die from complications related to childbirth than women in their 20s. In SA, non-pregnancy-related infections (e.g. HIV), obstetric haemorrhage and hypertension contributed to almost 70% of avoidable maternal deaths. In addition to the implementation of standardized preventive interventions to reduce obstetric haemorrhage and hypertension, better reproductive health services for adolescents, access to HIV care and treatment for women infected with HIV, and improved access to and uptake of long-acting reversible contraception are important ingredients for reducing maternal mortality among adolescents.

    The aim is to discuss why paediatricians should be involved in adolescent health care and provide youth-friendly-health-services. Global epidemiological data on morbidity and mortality demonstrate that much of ill health in the short and long run are connected to adolescent behaviour and in theory available for prevention. Young people seemingly lose their heads and do not consider dangers. Recent research on brain development provides us with an understanding how this may have a biological base. Also psychology has long taught us how adolescents use experimental behaviours as means to satisfy developmental needs and explore identity. Prevention and health promotion are areas of research where much more needs to be done. There is also a lack of venues for publishing even excellent studies in this field.

    The proportion of child and adolescent obesity in the United States has dramatically increased over the past few decades, challenging public health strategies and medical needs of the individual. The medical consequences of obesity include metabolic syndrome, polycystic ovary syndrome, and cardiovascular disease. There is no definite diagnostic criterion of metabolic syndrome in children and adolescents; commonly noted features are central adiposity, insulin resistance, dyslipidemia, and hypertension. To prevent negative health outcomes and early recognition for those at risk for overweight and obesity, healthcare providers should screen BMI in children and adolescents at least annually, as well as provide anticipatory guidance to all families during health maintenance visit. This review will address the epidemiology and consequences of obesity in children and adults, and issues for health care providers and public health officials to consider. These issues include increasing physical activity, decreasing sedentary activities, and promoting healthy eating behaviors.

    Approaches employed in counseling pregnant adolescents at the Crittenton Clinic in Boston are described. Concentrating on concrete issues of management of the pregnancy -- supplying information and exploring the pros and cons of various alternatives are advocated; probing into the psychological and emotional background of the pregnant adolescent is discouraged. Counseling about contraceptives and taking into account each individual situation are considered essential. Case studies are reviewed and figures representing the attitudes and contraceptive use of patients 1 year after abortion are presented. It is considered important to establish a trusting relationship with the adolescent, which will increase the likelihood that she will return for follow-up and additional help if she needs it.

  20. Targeting the adolescent male.

    PubMed

    Pitt, E

    1986-01-01

    The National Urban League regards too early parenting among adolescents as an issue requiring high level, active attention from all segments of the Black community. Poverty, single parent households and adolescent pregnancies are not exclusively female problems. The role that males play has been missing from too many studies of these phenomena. In light of the fact that most sexual activity is male initiated, and most sexual behavior is male influenced, it becomes clear that there will be no resolution of the problem of teenage pregnancy without directing greater attention to the male. The issue of male responsibility is skirted too often due to parental pride on the part of mothers and fathers when their male children seek sexual relations with female partners. It is viewed as a sign that they are developing sexually within the norm. This is especially true, in many instances, in female headed households where the mother is concerned that she may not be providing her son with an adequate male role model. Sexual activity by female adolescents, however, is generally not condoned. This confusing double standard is further compounded by the disjointed fashion in which American society responds to adolescent sexuality on the whole. Although the home should be the focal point, many parents reluctantly admit an inability to communicate effectively about sex with their pre-adolescent children. Thus, the school, church, community and social agencies have all been enlisted in this task. The National Urban League's initiative in this area is expected to have significant impact on the course of adolescent sexuality and reproductive responsibility.(ABSTRACT TRUNCATED AT 250 WORDS)

  1. [Adolescence and AIDS].

    1991-01-01

    The myths and prejudices that distort the reality and hide the true causes and effects of natural and social phenomena related to sexuality have a fertile ground in AIDS, given its obvious link to sex. The alarming spread of AIDS has been 1 result of these myths and prejudices. Human beings are sexual by nature; genital organs determine sex and also induce sexual behavior. It is by not fairly well accepted that an individual's sexuality exists from birth. Puberty usually begins at 12-16 years for both sexes. The physical changes of puberty terminate in the ability of the female to conceive and the male to procreate. The sexual excitation of adolescents resulting from production of various hormones can only be eliminated by some type of sexual satisfaction or sublimation. Sexuality, according to Freud, is an organizing principle of the personality. The sexual organs exist not merely for reproduction but to provide pleasure. Puberty signifies entry into active sex life. But the ideological structure of society, perpetuated by the family, schools, religion, the mass media, and other social institutions, sends confused signals to adolescents, requiring abstinence and virginity until marriage for women while encouraging sexual adventures for men. Adolescents are confronted by their new sexual feelings in the midst of a virtual bombardment of visual sexual stimuli from the mass media. It becomes impossible for adolescents to satisfy the requirements of appearances while also resolving the problems and pressures of their newly gained sexual maturity. Many adolescents become sexually active, and the problem is not to prevent sexual activity but to improve the conditions under which it occurs. Adolescents, lacking education and information about sex, begin their sex lives without protection. AIDS has now been added to the list of dire consequences that can result. A true sex education beginning in the home is needed to enable young people to develop healthy and full sex

    In Western society, approximately 3% to 5% of the population has at least one decorative tattoo, and the number of new tattoos has increased dramatically over the last decade. Tattooing is becoming increasingly popular among adolescents. Pediatric nurse practitioners (PNPs) are in key positions to counsel preadolescents and adolescents about tattoos. PNPs should be knowledgeable about the care, potential adverse reactions, risks of blood-borne diseases, and removal of tattoos. PNPs should also have an understanding of who gets tattoos, why they get tattoos, and what type of regulations exist related to tattooing in the United States. PMID:11174653

    1990-01-01

    Existing studies of the sexual content of television programming and advertising and the effects of this content on adolescent viewers are reviewed. Content studies show that the frequency of sexual references have increased in the past decade and are increasingly explicit. Studies of the effects of this content, while scarce, suggest that adolescents who rely heavily on television for information about sexuality will have high standards of female beauty and will believe that premarital and extramarital intercourse with multiple partners is acceptable. They are unlikely to learn about the need for contraceptives as a form of protection against pregnancy or disease. Suggestions for future research and trends in television programming policies are explored.

    First the difficulties with the concept of depression, its definition and with the classification and heterogeneity of the depressive syndromes are pointed out. The particular clinical importance of depressive states, especially of adolescents, is shown by means of epidemiological data. A case report illustrates the classification problems and a part of the typical conflicts and psychic demands in adolescence. Then follows a short survey on the conception of depressive states in psychoanalysis, with special reference to this age group. The evaluation of the given studies calls for interdisciplinary research, in order to tackle the still unsolved questions concerning depressive conditions and to improve the coordination of separate findings.

    Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects the child and adolescent population. It is characterized by impairment in attention/concentration, hyperactivity, and impulsivity, all of which can impact performance of athletes. ADHD treatment within the athletic population is a unique challenge. The research in this field has been relatively limited. The National Collegiate Athletic Association and International Olympic Committee both regulate the use of psychostimulants for treatment of ADHD due to their performance-enhancing effects. In this article, authors have discussed the screening methods, pharmacological treatment, side effects, and behavioral approaches for the treatment of ADHD in adolescent athletes. PMID:24987666

    Varicocoele is defined as excessive dilatation of the pampiniform venous plexus of the spermatic cord. Varicocoele frequently appears during early puberty and is recognized to be the most common surgically correctable cause of male infertility. However, the actual incidence in adolescents, pathophysiology and the association with male factor infertility all remain somewhat controversial. The most accurate diagnostic technique for identifying young men who will benefit from surgical treatment has yet to be established. Observations of testicular asymmetry and deteriorating semen quality helped establish current guidelines and recommendations for surgical treatment. Further studies, comparing observation with surgical intervention, are needed to refine the current indications for varicocoele repair in the adolescent male. PMID:23258638

    1983-01-01

    Five baseball pitchers, three college and two professional, with an average age of 24 years, exhibited pain between the acceleration phase and follow-through phase of the pitching motion. This caused the players to be unable to continue at the level of competition necessary to play. A significant osteophyte on the posteromedial aspect of the olecranon process was identified in all pitchers. This caused impingement with the articular wall of the olecranon fossa and often created an area of chondromalacia. The more commonly identified posterior osteophyte was present in all cases. However, if just this posterior osteophyte is removed, the described lesion will be missed, with resultant persistent disability. Surgical excision of the posteromedial osteophyte through a relatively atraumatic posterolateral approach allowed early return of function without morbidity. With an average follow up of 1 year, all of the pitchers returned for one full season at maximum effectiveness.

    2010-03-01

    Adolescence, between the ages of 10 and 19 years, is a unique period both physically and emotionally. During this time of life, individuals are known to experiment and engage in risky behavior, sometimes with unforeseen morbidity and mortality. We also see suicide emerge as a manner of death in this age group. The most common method is gunshot wound and sometimes in the form of Russian roulette. Few studies have looked at deaths by Russian roulette, the victims, and scenarios. In particular, no study examines the adolescent victim of Russian roulette. To better understand and classify this entity, adolescent Russian roulette autopsy cases over a 20-year period were examined looking at the victims, scenarios, autopsy findings, cause and manner of death, and the weapons. All victims were males, ages 13 to 19 years, with a Black-to-White ratio of 1:1. No victim had a previous psychiatric history. Toxicology was positive for alcohol and/or marijuana in 50% of the victims. Friends were present when the victim shot himself which occurred in the home the majority of the time. In all but 1 case, premeditation of the game was involved as the victim provided the weapon for the roulette. The cause of death was gunshot wound to the head (6 to the right side, 1 to the mouth, 1 to the forehead), and the manner of death was suicide in 6 cases and accident in 2 cases. A review of the literature discusses the adolescent victim, suicide, and Russian roulette.

    Etiological theories of suicide are reviewed from epidemiological, individual (both biological and psychological), and psychosocial perspectives. Cohort and population-model approaches as explanations for the two- to three-fold increase in completed suicide rates observed in adolescents and young adults over the past 25 years are presented. The results of the authors' study of suicides in adolescents and young adults in Cuyahoga County, Ohio, to test these hypotheses are summarized. This study revealed marked cohort differences in suicide rates and provided partial support for the "population-model" approach. Differences between suicide rates in adolescents and other age groups are discussed, as are data from some minority groups. The role of depression in adolescents and various studies of diagnostic approaches (e.g., structured diagnostic assessments, biological markers, clues during intensive psychotherapy or psychoanalysis, studies of high-risk diagnostic groups) are reviewed. Lastly, treatment employing individual, family, and group approaches to classical psychoanalytic or cognitive psychotherapy as well as the role of pharmacological treatments are considered.

    It is increasingly necessary that pediatricians have greater knowledge of adolescent health. To begin with they should be familiar with the psychosocial development of this period, an issue which is imperative for the health care of the age group. With that purpose, this article reviews the normal adolescent psychosocial development. Adolescence is a stage that has been progressively prolonged, during which fast and big changes occur, that lead human beings to become biologically, psychologically and socially mature, and potentially able to live independently. Developmental tasks of this period are the establishment of identity and the achievement of autonomy. Although it is a process of high individual variability in terms of its beginning and end, the progression through stages, the synchrony of development between the various areas, and in other aspects, the psychosocial development of this period usually have common characteristics and a progressive pattern of 3 phases: early, middle and late adolescence. Psychological, cognitive, social, sexual and moral development of young people in each of them are described in this article. PMID:26342392

Parents and adolescent can need support and advice to obtain that this stage, in conflicting occasions, is developed normally, so that the adolescent become a capable adult about caring whether same and about others, with a life style that favor the integrated operation and the continued development. The family nurse can lend them the support and advice that need, since occupies a privileged place in the health equipment to guarantee the continuity of the assistance to the familiar group from the birth until the maturity. Basing us on the theory of the self-care developed by D. Orem, we will check the specific requirements of self-care of this stage of the vital cycle, of great transcendency for the step to the adult age. PMID:10514786

    It is increasingly necessary that pediatricians have greater knowledge of adolescent health. To begin with they should be familiar with the psychosocial development of this period, an issue which is imperative for the health care of the age group. With that purpose, this article reviews the normal adolescent psychosocial development. Adolescence is a stage that has been progressively prolonged, during which fast and big changes occur, that lead human beings to become biologically, psychologically and socially mature, and potentially able to live independently. Developmental tasks of this period are the establishment of identity and the achievement of autonomy. Although it is a process of high individual variability in terms of its beginning and end, the progression through stages, the synchrony of development between the various areas, and in other aspects, the psychosocial development of this period usually have common characteristics and a progressive pattern of 3 phases: early, middle and late adolescence. Psychological, cognitive, social, sexual and moral development of young people in each of them are described in this article.

    The genital examination is not a routine part of health maintenance assessment in prepubertal and pubertal girls. However, evaluation of minors for suspected sexual abuse has been addressed extensively in the last two decades. In spite of this, normal anatomic variations and developmental changes are not fully investigated. This paper reviews current knowledge about the hymen, with a focus on puberty and adolescence. More is known about the external genitals of prepubertal children than of adolescent girls. No longitudinal studies have been performed among girls older than age 3. Tanner staging does not include detailed genital development. A variety of terms have been used to describe the configuration and/or distortion of the hymen: attenuation, clefts, tears and transections, bumps and notches. No studies have been published on the normal variations of the width of the hymenal rim, although an attenuated and/or narrow rim is categorized as consistent with penetrative sexual abuse according to an international consensus statement. Critiques of the literature on the hymen have been published by experts on forensic medicine, emphasizing the fact that the normal hymenal appearance in adolescents still is not well documented. Few studies on hymenal configuration in nonabused adolescent girls have been performed, including girls with and without experience of consensual vaginal intercourse and use of tampons. Longitudinal investigations are required for a better knowledge of female genital development during puberty, with a special focus on vulvar and hymenal anatomy. PMID:12380450

    2016-01-01

    Adolescents presenting with gender-related concerns are increasingly seeking support from providers from a variety of disciplines within health care settings across the world. For those treating young people who meet the criteria for the DSM 5 diagnosis of gender dysphoria (GD), complex decisions in clinical care are common. Defining best practice with this population with respect to interventions that span mental health, physical, and surgical domains can be challenging, given a relative dearth of empirical data available; yet practice guidelines have emerged from different professional organizations which can aid with this. For this review paper, a broad literature search was performed to identify relevant studies pertaining to the care of adolescents with GD. In addition, an overview of trends in clinical practice, including shifts in conceptualization of how clinicians and patients define care that is considered affirming when working with this population, is described. This paper explores the characteristics of referral patterns to specialized clinics, provides a brief overview of gender identity development in adolescence, and then describes the phenomenology of known aetiological factors and co-occurring psychiatric issues in adolescents with GD. Additionally, clinical management considerations that detail assessment aims and common treatment interventions across disciplines will be explored. PMID:26828376

  6. Psychotherapy with native adolescents.

    PubMed

    Katz, P

    1981-11-01

    Psychotherapy with native adolescents requires that the therapist learn about a different set of values, develop new communication skills, and re-examine many of his practices. Varying with the individual tribe, the attitudes to time, property and anger may be significantly different from the values of the white culture. Many of the Indian adolescents rely heavily on non-verbal communication, requiring an increased sensitivity by the therapist to this form of communication. The therapist may need to review his office setting, with an eye to making it less alien, and because of the different attitude to time, he may have to adjust the time structure of his practice, often using more than the fifty-minute hour. Treatment begins with an exploration of Indian-White difficulties, especially the stereotyping of all whites. It then focuses on helping the adolescents to establish their own individual identity, bucking the stereotypes that are projected on them. Examples are given from the author's own practice with Cree and Saulteaux-Ojibway adolescents.

    Hypermobility of the first ray, which is caused by an instability of the first metatarsocuneiform joint, is one of the factors that induces hallux valgus and can be caused by technical mistakes in ballet practice. Correlation between ballet practice and hypermobility of the first ray. Using a modified Klaue device, mobility of the first metatarsocuneiform joint was measured (hypermobility ≥ 10mm) in both dorsal and dorso-medial directions in 264 feet in 2 groups of people: ballet dancers (non professional) and a control group of non-dancers. 45° mobility is statistically higher than dorsal mobility, and mobility in the ballet dancer group is higher than in the control group, but there is no correlation between hours of ballet and en-pointe shoe practice, and hypermobility of the first ray. First ray hypermobility, and even hallux valgus, in ballet practice is related to anatomical-hereditary factors and to incorrect technical execution. PMID:23738311

    High adolescent fecundity principally affects developing countries. In spite of a decrease in the incidence of pregnancies in the developing countries over the past 13 years, the differences that exist with respect to developed countries turn adolescent fecundity into an indicator of the level of development of countries. The impact of adolescent pregnancy is evident in maternal and perinatal morbidity and mortality. Nonetheless, in addition to the age involved in precocious pregnancy, it also reflects previous conditions such as malnutrition, infectious diseases and deficiencies in the health care given to pregnant adolescents. The most important impact lies in the psychosocial area: it contributes to a loss of self-esteem, a destruction of life projects and the maintenance of the circle of poverty. This affects both adolescent mothers and fathers; the latter have been studied very little. Intervention with comprehensive health services and the maintenance of the education of adolescent mothers and fathers prevents repeat pregnancies. Evidence shows success in the prevention of the first pregnancy when the intervention includes comprehensive sexual education, the existence of preferential sexual and reproductive health services for adolescents, the handout of modern contraceptives gauged to the adolescence stage of the subjects and the existence of an information network. There is little research in contraception for adolescents, and for this reason, the indications given are projections of data obtained from adults. PMID:20167542

    2003-11-01

    Polycystic ovary syndrome (PCOS) is a common disorder among reproductive-age women, yet the diagnosis may be overlooked during adolescence. Although the clinical and metabolic features are similar to those found in adult women, it can be difficult to distinguish the young woman with PCOS from a normal adolescent. Irregular menses, anovulatory cycles, and acne are not uncommon in adolescent women. Adolescents with a history of premature pubarche, a family history of PCOS, Caribbean-Hispanic and African-American ancestry, and/or obesity are at risk for PCOS and deserve close surveillance. The laboratory evaluation of the adolescent with suspected PCOS or hyperandrogenism should be individualized based on the history, symptoms, and examination findings. The cornerstone of management of PCOS in adolescence includes either a combination oral contraceptive or progestin. Consideration of insulin-sensitizing agents, antiandrogens, topical treatments for acne, and various treatments for hair removal are dependent on the patient's symptoms and concerns. Healthy eating, regular exercise, and for the overweight adolescent, weight reduction, are encouraged to reduce the risk of cardiovascular disease and type II diabetes mellitus. Numerous studies have shown that weight loss and exercise decrease androgen levels, improve insulin sensitivity, and lead to the resumption of ovulation. Although initial studies suggest that Metformin may be particularly useful for treating the PCOS adolescent with insulin resistance and obesity, additional studies are needed to determine the efficacy and long-term outcome. Management of the adolescent with PCOS is challenging and requires a supportive, multidisciplinary team approach for optimal results.

    Childhood obesity remains a significant public health issue. Approximately 8% of adolescent girls and 7% of adolescent boys have severe (≥class 2) obesity. Adolescent severe obesity is associated with numerous comorbidities, and persists into adulthood. Bariatric surgery is the most effective treatment available, resulting in major weight loss and resolution of important comorbid conditions. Clinical practice guidelines for pediatric obesity treatment recommend consideration of surgery after failure of behavioral approaches. Careful screening and postoperative management of patients by a multidisciplinary team is required. Long-term studies are needed to assess the impact of adolescent bariatric surgery. PMID:27519138

    We explored young people and parents' views on adolescent drinking and safety in the locations where drinking may occur. Focus groups with adolescents and parents showed that many believed adolescent drinking and drunkenness is normative. Younger adolescents had more negative views of adolescent drinkers than their older peers. Adolescent drinking occurred in private settings and parents made decisions about allowing their adolescent children to attend social events based on the level of safety attributed to the location. If adolescent drinking was likely then home was the preferred location as it provided scope for risk minimisation. Positive portrayals of non-drinking adolescents and information to assist parents' decision-making are needed.

    Forty volunteer subjects were interviewed in an attempt to determine if indications of adolescent rebellion would be found across the range of disciplinary styles. An analysis of the taped interviews did not support the expectations. Twenty-five percent of the sample manifested high rebelliousness and none of these subjects came from low-control homes. Seveny-five percent of the sample showed little or no rebelliousness at all. Low rebelliousness was evently distributed across the spectrum of disciplinary styles. The twenty per-cent incidence of permissive homes was higher than other research indicated it might be. Authoritarian parents in this sample appeared to be less restricting than would have been expected. A wider range of adolescent behavior was accepted and fewer issues provoked conflict and rebellion as the parents appeared to be responding to a changing society.

    2015-01-01

    Adolescent idiopathic scoliosis (AIS) is the most common form of structural spinal deformities that have a radiological lateral Cobb angle - a measure of spinal curvature - of ≥10(°). AIS affects between 1% and 4% of adolescents in the early stages of puberty and is more common in young women than in young men. The condition occurs in otherwise healthy individuals and currently has no recognizable cause. In the past few decades, considerable progress has been made towards understanding the clinical patterns and the three-dimensional pathoanatomy of AIS. Advances in biomechanics and technology and their clinical application, supported by limited evidence-based research, have led to improvements in the safety and outcomes of surgical and non-surgical treatments. However, the definite aetiology and aetiopathogenetic mechanisms that underlie AIS are still unclear. Thus, at present, both the prevention of AIS and the treatment of its direct underlying cause are not possible. PMID:27188385

Most authors support the subjectivity and impression of this field of investigation. We consider some relevant aspects in adolescence and the effects of the illness situation on it. We concluded it's necessary to realize particular and individual analysis of this problem, because it's not possible to report a general conclusion. However, it's possible to realize some predictions about some conflict global areas of behaviour and personality. We analyze the trends of behaviour, adaptative or not, and the differential effects of the illness (chronic and acute). We review the effects of the life-events and the social support on the behaviour, and the relevancy of some particular and transitory aspects of the people on his behaviour. PMID:2075843

    Loss, failure and desertion are those words, which better describe the most frequent difficulties incurred by teenagers, and their relation to the school environment, and indicate, as well, the lack of connection between individual aspirations and school achievements obtained. Despite the likelihood of school difficulties throughout the entire educational career, from the kindergarten to the college, we are able to recognize certain specific "disturbances" which come out during the adolescence, basically relating to the school experiences. School failure, school desertion and school abandonment are, in fact, issues mainly discussed in coincidence with the beginning of the adolescent age and the attending of the high school. The aetiopathogenesis of school discomfort is mostly determined by more than only one factor: psychological, physical, cognitive and environmental aspects, all together, contribute in various ways, to the rise and persisting of the above described problems. Suggesting a univocal characterization of the adolescent with school difficulties, is indeed a hard task, since school failure is not an exclusive feature of only one kind of personality or the expression of only one type of conflict. Once identified the individuals more subject to risk, and the warning signs of actual uneasiness, it is important therefore to intervene timely and in different ways in order to avoid the worsening or the excessive extension of the school difficulties and of their frequent and serious consequences on the teenagers' individual and domestic well-being. Such type of prevention definitely belongs to the Adolescent Medicine, and must be developed on different levels, by involving not only the teenagers, but also their families, the school, and the whole social environment in which the teenagers live and with which they interact.

    2010-01-01

    PROBLEM Korean American adolescents tend to experience more mental health problems than adolescents in other ethnic groups. METHODS The goal of this study was to examine the association between Korean American parent-adolescent relationships and adolescents’ depressive symptoms in 56 families. FINDINGS Thirty-nine percent of adolescents reported elevated depressive symptoms. Adolescents’ perceived low maternal warmth and higher intergenerational acculturation conflicts with fathers were significant predictors for adolescent depressive symptoms. CONCLUSIONS The findings can be used to develop a family intervention program, the aim of which would be to decrease adolescent depressive symptoms by promoting parental warmth and decreasing parent-adolescent acculturation conflicts.

    2013-01-01

    To examine morphological differences in Morton's interdigital neuroma between two elderly human populations, we conducted comparative study using 40 Japanese (27 males, 13 females; mean age, 81.2 years) and 21 Finnish (6 males, 15 females; mean age, 80.5 years) cadavers. We defined the neuroma as a thickening of the nerve of at least two-fold relative to the non-pathological proximal part. The incidence of this neuroma was 25% (10/40) in the Japanese and 33.3% (7/21) in the Finnish cadavers. Moderate or severe hallux valgus (with an angle of more than 20 degrees) was seen in half of the 40 Japanese cadavers (7 males, 13 females), but was absent in the Finnish cadavers. Such hallux valgus was present in 7 (5 males, 2 females) of the 10 Japanese cadavers with neuroma. Moreover, in 2 Japanese cadavers, a paper-like, specialized type of neuroma was associated with the deformity. Pathogenesis of Morton's neuroma might be different between human populations with or without hallux valgus.

    2014-01-01

    The mechanical response of human metatarsal bones is of importance in both research and clinical practice, especially when associated with the correction of Hallux Valgus. Verified and validated patient-specific finite-element analysis (FEA) based on CT scans developed for human femurs are extended here to the first and second metatarsal bones. Two fresh-frozen metatarsal #1 and five metatarsal #2 bones from three donors were loaded in-vitro at three different angles. Holes typical to Hallux Valgus correction were then drilled in the bones, which were reloaded until fracture. In parallel, high-order FE models of the bones were created from CT-scans that mimic the experimental setting. We validated the FE results by comparison to experimental observations. Excellent agreement was obtained with R(2)=0.97 and slope of the regression line close to 1. We also compared the FE predicted fracture load and location for the second metatarsal bones with these measured in the experiment, demonstrating an excellent prediction within 10% difference. After validation of the FE predictions, they were used to investigate the effect of drilled hole position, dimension and the insertion of a metallic device on the mechanical response so to optimize the outcome of the Hallux Valgus correction. This study further substantiates the potential use of FEA in clinical practice.

    2014-01-01

    Reconstructive osteotomies for the treatment of Hallux valgus are among the most prevalent procedures in foot and ankle surgery. The combination of biodegradable materials with an innovative method for fixation by application of ultrasonic energy facilitates a new bonding method for fractures or osteotomies. As clinical experience is still limited, the aim of this study was to assess the safety and performance of the SonicPin system for fixation of Austin/Chevron osteotomies. Chevron osteotomy was performed on 30 patients for the treatment of Hallux valgus. The used SonicPins were made from polylactide and are selectively melted into the cancellous bone structure during insertion by ultrasonic energy. Patients were followed for one year, which included X-ray and MRI examinations as well as evaluation of life quality by EQ-5D (EuroQol). The MRI after three months showed adequate bone healing in all cases and no signs of foreign body reactions, which was again confirmed by MRI 12 months postoperatively. The bony healing after 12 months was uneventful without any signs of foreign body reactions. In summary, based on the low complication rate and the significant improvement in health related quality of life (EQ-5D) reported in this study, fixation of an Austin/Chevron osteotomy with a SonicPin for treatment of Hallux valgus can be considered to be safe and efficient over the short term. Level of Clinical Evidence: Therapeutic Level III. PMID:24851140

    2003-02-01

    To improve the well-being of adolescents with epilepsy, research is needed on how adolescents cope. In this study, Lazarus' model of stress and coping and Antonovsky's Theory of Sense of Coherence were used as the theoretical framework. The aim was to describe the lived experience of adolescents with epilepsy and their coping skills. The participants were 13-19 years old with an epilepsy diagnosis but without mental retardation or cerebral palsy. The study was performed in southern Sweden at the pediatric department of a university hospital. Semistructured and open-ended interviews were conducted with 13 adolescents. The transcripts were analyzed with manifest and latent content analysis. All the adolescents had developed strategies to cope with the emotional strains caused by epilepsy. They experienced strains from the seizures, limitation of leisure activities, side effects of medication, and feelings of being different. The coping strategies described were finding support, being in control, and experimenting.

    Adolescence is the developmental epoch during which children become adults – intellectually, physically, hormonally, and socially. Adolescence is a tumultuous time, full of changes and transformations. The pubertal transition to adulthood involves both gonadal and behavioral maturation. Magnetic resonance imaging studies have discovered that myelinogenesis, required for proper insulation and efficient neurocybernetics, continues from childhood and the brain’s region-specific neurocircuitry remains structurally and functionally vulnerable to impulsive sex, food, and sleep habits. The maturation of the adolescent brain is also influenced by heredity, environment, and sex hormones (estrogen, progesterone, and testosterone), which play a crucial role in myelination. Furthermore, glutamatergic neurotransmission predominates, whereas gamma-aminobutyric acid neurotransmission remains under construction, and this might be responsible for immature and impulsive behavior and neurobehavioral excitement during adolescent life. The adolescent population is highly vulnerable to driving under the influence of alcohol and social maladjustments due to an immature limbic system and prefrontal cortex. Synaptic plasticity and the release of neurotransmitters may also be influenced by environmental neurotoxins and drugs of abuse including cigarettes, caffeine, and alcohol during adolescence. Adolescents may become involved with offensive crimes, irresponsible behavior, unprotected sex, juvenile courts, or even prison. According to a report by the Centers for Disease Control and Prevention, the major cause of death among the teenage population is due to injury and violence related to sex and substance abuse. Prenatal neglect, cigarette smoking, and alcohol consumption may also significantly impact maturation of the adolescent brain. Pharmacological interventions to regulate adolescent behavior have been attempted with limited success. Since several factors, including age, sex

    PubMed

    Friedman, H L

    1994-01-01

    The health and well-being of adolescents is closely intertwined with their physical, psychological and social development, but this is put at risk by sexual and reproductive health hazards which are increasing in much of the world. Changes in population growth and distribution, the rise of telecommunications, the increase in travel and a decline in the family, as well as a generally earlier start of menarche and later age of marriage are contributing to an increase in unprotected sexual relations before marriage. This, combined with risks from early marriage, result in too early or unwanted pregnancy and childbirth, induced abortion in hazardous circumstances and sexually transmitted diseases, including HIV infection leading to AIDS. With more than half the world's population below the age of 25, and 4 out of 5 young people living in developing countries with inadequate access to prevention and care, there is an urgent need for action. Young women are particularly vulnerable. Mortality and morbidity from early pregnancy whether ending in childbirth or abortion, is much higher for the younger adolescent. Young women, especially those who have less formal education, are more vulnerable to pressures for marriage, or sexual relations before marriage, often with older men. Young people generally lack adequate knowledge about their own development and information on how to get help. Those who could help are rarely trained for working with adolescents, and services which are generally designed for adults or children often deter young people from getting help when they most need it. Policy and legislation relating to sexual and reproductive health issues are often contradictory, and unclear or unenforced.(ABSTRACT TRUNCATED AT 250 WORDS)

Multiple regression analyses were used to analyse questionnaire data obtained from 2799 adolescents (mean age 14.3) in 2006. The results show a negative association of the father's, but not mother's unemployment or non-employment with adolescents' health. Regression analyses showed that neither financial strain nor a poor parent-adolescent relationship or a low score in resilience accounted for the relationship between the father's unemployment or non-employment and poorer adolescent health. Furthermore, resilience did not work as a buffer against the negative impact of fathers' unemployment on adolescents' health.

  8. ADOLESCENT ALCOHOL EXPOSURE: ARE THERE SEPARABLE VULNERABLE PERIODS WITHIN ADOLESCENCE?

    There are two key alcohol use patterns among human adolescents that confer increased vulnerability for later alcohol abuse/dependence, along with neurocognitive alterations: (a) early initiation of use during adolescence, and (b) high rates of binge drinking that are particularly prevalent late in adolescence. The central thesis of this review is that lasting neurobehavioral outcomes of these two adolescent exposure patterns may differ. Although it is difficult to disentangle consequences of early use from later binge drinking in human studies given the substantial overlap between groups, these two types of problematic adolescent use are differentially heritable and hence separable to some extent. Although few studies using animal models have manipulated alcohol exposure age, those studies that have have typically observed timing-specific exposure effects, with more marked (or at least different patterns of) lasting consequences evident after exposures during early-mid adolescence than late-adolescence/emerging adulthood, and effects often restricted to male rats in those few instances where sex differences have been explored. As one example, adult male rats exposed to ethanol during early-mid adolescence (postnatal days [P] 25-45) were found to be socially anxious and to retain adolescent-typical ethanol-induced social facilitation into adulthood, effects that were not evident after exposure during late-adolescence/emerging adulthood (P45-65); exposure at the later interval, however, induced lasting tolerance to ethanol's social inhibitory effects that was not evident after exposure early in adolescence. Females, in contrast, were little influenced by ethanol exposure at either interval. Exposure timing effects have likewise been reported following social isolation as well as after repeated exposure to other drugs such as nicotine (and cannabinoids), with effects often, although not always, more pronounced in males where studied. Consistent with these timing

    The Canadian nationally syndicated newspaper column entitled "Youth Clinic" during a four-year period received over 4,000 letters from young people. This article highlights the prominent themes of these letters and points out the recurrent concerns of those youth who are predisposed to writing. The most common themes have to do with the adolescents' sense of isolation from peers and adults. The difficulties in adequately responding to genuine but anonymous letters, the problems inherent in only publishing a small proportion of the letters received, and the potential uses of such a column, are discussed.

    Besides its emotional, hormonal and physical components, sexuality has also an important social function. Analyzing these interactions in immigrant adolescents who are challenged at the same time by developmental changes and modified cultural and social rules--especially if they differ from the rules assimilated during childhood--might help professionals to access better comprehension. Personal experience, individual and external resources, whether they are family oriented or professional, are prone to influence on behavior, perception and outcome related to sexual health. The subject is discussed on the base of scientific literature and medical practice.

    Online social networking is a 21st century innovation increasingly embraced by today's young people. It provides new opportunities for communication that expand an adolescent's world. Yet adults, often suspicious of new trends and technologies initially embraced by youth, often see these new environments as perilous places to visit. These fears have been accentuated by media hype, especially about sexual predators. How dangerous are they? Because the rush to go on these sites is a new phenomenon, research is as yet scant. This review explores current beliefs and knowledge about the dangers of social networking sites.

    The physician provides a much-needed service to teenagers by counseling them regarding sexuality. A series of conferences during adolescence and use of questionnaires can facilitate discussion and point up potential problems. When the patient is confronted with a problem such as a need for contraception or an unwanted pregnancy, the physician should present all the options available and leave the final choice up to the patient. The physician is not obligated to participate in a solution that is counter to his or her moral values. PMID:7071042

    Adolescence encompasses a sensitive developmental period of enhanced clinical vulnerability to nicotine, tobacco, and e-cigarettes. While there are sociocultural influences, data at preclinical and clinical levels indicate that this adolescent sensitivity has strong neurobiological underpinnings. Although definitions of adolescence vary, the hallmark of this period is a profound reorganization of brain regions necessary for mature cognitive and executive function, working memory, reward processing, emotional regulation, and motivated behavior. Regulating critical facets of brain maturation are nicotinic acetylcholine receptors (nAChRs). However, perturbations of cholinergic systems during this time with nicotine, via tobacco or e-cigarettes, have unique consequences on adolescent development. In this review, we highlight recent clinical and preclinical data examining the adolescent brain's distinct neurobiology and unique sensitivity to nicotine. First, we discuss what defines adolescence before reviewing normative structural and neurochemical alterations that persist until early adulthood, with an emphasis on dopaminergic systems. We review how acute exposure to nicotine impacts brain development and how drug responses differ from those seen in adults. Finally, we discuss the persistent alterations in neuronal signaling and cognitive function that result from chronic nicotine exposure, while highlighting a low dose, semi-chronic exposure paradigm that may better model adolescent tobacco use. We argue that nicotine exposure, increasingly occurring as a result of e-cigarette use, may induce epigenetic changes that sensitize the brain to other drugs and prime it for future substance abuse.

    Many smoking cessation programs for adult smokers are described in the medical and nursing literature. Programs designed to prevent smoking among adolescents and children also are prevalent in the literature. Despite these prevention programs, many adolescents choose to start smoking. Once adolescents begin smoking, it is difficult to find ways to help them quit. Few programs exist that are targeted to help this population with smoking cessation. This article provides an in-depth review of 5 smoking cessation programs designed for adolescents. Each of the programs presents unique strategies for helping teenage smokers quit. Techniques used in these programs include peer leadership, nicotine patch therapy, peer support, computer instruction, and one-on-one counseling with a nurse practitioner. Each program was studied for efficacy with adolescents. Although none of the programs reviewed showed remarkable success, they serve as guides for future program development. Additional programs need to be developed and studied with larger, more diverse populations. Nurses must identify or develop smoking cessation programs that meet the needs of all types of adolescents and are effective in helping them to quit. Once designed, these smoking cessation programs should be made accessible to adolescents in a variety of settings.

    2011-11-01

    This paper briefly reviews the research literature on motivational interviewing (MI) and behaviour change in adolescents and then discusses the implications of adolescent cognitive and social-emotional developmental processes for the relational and technical components of MI. Research suggests that MI is efficacious in improving substance use in adolescents. Research has been slower to emerge in other behaviours, but available randomized controlled trials suggest that MI has great promise for improving mental and physical health outcomes in this developmental period. The relational and technical components of MI are highly relevant for the adolescent developmental period, and studies have shown that these components are related to outcomes in this population. There are several ways to include MI in clinical interventions for adolescents, ranging from MI in brief settings to using MI as a platform from which all other treatments are offered. Future research is necessary to test the effects of MI in adolescent group settings and the full integration of MI into other adolescent treatment approaches. PMID:22114919

    To explore the meaning and function of attachment organization during adolescence, its relation to multiple domains of psychosocial functioning was examined in a sample of 131 moderately at-risk adolescents. Attachment organization was assessed using the Adult Attachment Interview; multiple measures of functioning were obtained from parents, adolescents, and their peers. Security displayed in adolescents' organization of discourse about attachment experiences was related to competence with peers (as reported by peers), lower levels of internalizing behaviors (as reported by adolescents), and lower levels of deviant behavior (as reported by peers and by mothers). Preoccupation with attachment experiences, seen in angry or diffuse and unfocused discussion of attachment experiences, was linked to higher levels of both internalizing and deviant behaviors. These relations generally remained even when other attachment-related constructs that had been previously related to adolescent functioning were covaried in analysis. Results are interpreted as suggesting an important role for attachment organization in a wide array of aspects of adolescent psychosocial development. PMID:9839424

    Immaturities in adolescent reward processing are thought to contribute to poor decision making and increased susceptibility to develop addictive and psychiatric disorders. Very little is known; however, about how the adolescent brain processes reward. The current mechanistic theories of reward processing are derived from adult models. Here we review recent research focused on understanding of how the adolescent brain responds to rewards and reward-associated events. A critical aspect of this work is that age-related differences are evident in neuronal processing of reward-related events across multiple brain regions even when adolescent rats demonstrate behavior similar to adults. These include differences in reward processing between adolescent and adult rats in orbitofrontal cortex and dorsal striatum. Surprisingly, minimal age related differences are observed in ventral striatum, which has been a focal point of developmental studies. We go on to discuss the implications of these differences for behavioral traits affected in adolescence, such as impulsivity, risk-taking, and behavioral flexibility. Collectively, this work suggests that reward-evoked neural activity differs as a function of age and that regions such as the dorsal striatum that are not traditionally associated with affective processing in adults may be critical for reward processing and psychiatric vulnerability in adolescents.

    Study Objectives: Developed the Cleveland Adolescent Sleepiness Questionnaire (CASQ), a brief, self-completed instrument to measure excessive daytime sleepiness in adolescents. Design: Cross-sectional analysis. Participants: A subsample of 411 adolescents 11–17 years of age recruited from area schools, churches, and “control” participants in a sleep disordered breathing cohort study; a second subsample of 62 adolescents with diagnosed sleep disordered breathing also participating in the sleep disordered breathing study. Measurements: Participants completed the CASQ along with two other available measures of daytime sleepiness and other sleep parameters (sleep duration on school nights, sleep duration on non-school nights, and sleep debt, defined as non-school night sleep duration minus school-night sleep duration). Demographic information was obtained from a caregiver-completed questionnaire. The CASQ was developed using exploratory factor analysis, followed by confirmatory factor analysis using structural equation modeling techniques. Results: Goodness-of-fit measures for the final 16-item scale structure ranged from good to excellent. The CASQ's internal consistency was good (α = 0.89). Correlations between the CASQ, two other measures of daytime sleepiness, and sleep parameters gave preliminary evidence of the CASQ's construct validity. Conclusion: The CASQ shows promise as a valid measure of daytime sleepiness in adolescents. Citation: Spilsbury JC; Drotar D; Rosen CL et al.

    Abstract Background: Physician counseling on lifestyle factors has been recommended as one way to help combat the obesity epidemic in the United States. The aim of this study was to examine the frequency of lifestyle counseling among healthy weight, overweight, and obese adolescents and determine the contributions of adolescent weight and physical activity. Methods: Self-reported surveys on dietary and physical activity counseling, along with measured height, weight, and physical activity data by accelerometry were collected on 76 adolescents ages 11–14 years. General linear models tested for associations of reported lifestyle counseling by weight category, adjusting for physical activity, age, gender, race/ethnicity, and parent education. Results: Half (47%) of the subjects were overweight or obese. Frequency of lifestyle counseling varied by weight category, with obese adolescents reporting greater amounts of lifestyle counseling across all topics than their peers. Obese adolescents received more dietary (β=0.88; standard error [SE]=0.25; p=0.001) and physical activity (β=0.80; SE=0.28; p=0.006) counseling than healthy weight youth, as well as being told to increase their physical activity more often (β=0.96; SE=0.29; p=0.001). There were no differences in lifestyle counseling between overweight and healthy weight subjects. Adolescents with greater daily moderate-to-vigorous physical activity reported less physical activity counseling (β=–0.02; SE=0.008; p=0.05). Conclusions: Despite universal recommendations to counsel adolescents on lifestyle, only obese adolescents consistently report receiving such counseling. Given known difficulties in reversing obesity after onset, efforts should ensure that all adolescents receive lifestyle counseling. PMID:24617855

    From the beginning of the twentieth century, youthful suicide has posed both a clinical and a theoretical challenge for psychoanalysis. This paper examines several paradigmatic cases of completed suicide in order to illustrate important psychodynamic aspects of adolescent suicide. The contributions of the developmental psychoanalytic perspective to our understanding of adolescent self-destructiveness are discussed, with particular emphasis on Anna Freud's concept of developmental lines toward self-care and self-regulation. The applications of this developmental psychoanalytic perspective to clinical research on vulnerability to adolescent suicide are reviewed. PMID:9029973

    The provision of contraception to adolescents requires specific attention. Adolescents require contraceptive methods which are safe, effective and simple to use. While long-acting reversible contraceptive methods are preferable, they should have a choice and not be forced or mandated especially in situations where this may compromise safety. After counselling they should have the ability to choose any method of contraception. Under the appropriate circumstances, each method of contraception may have a place. This chapter will be devoted to evaluating the most current scientific rationale for the indication for use of each method of contraception in adolescents.

    Adolescents living in the Indian subcontinent form a significant proportion of the general population. India is home to 236 million adolescents, who make up one-fifth of the total population of India. Adolescent health is gradually considered an important issue by the government of India. Awareness is increasing about adolescent needs. Health care professionals in particular are becoming more interested in the specific needs of adolescent age. Adolescent medicine as a subspecialty of pediatrics has also gained importance gradually over the last decade. In a hospital setting, adolescent-specific needs are met, albeit not in a uniform manner in all the health centers. After having been trained in adolescent medicine in India and abroad, I present this paper as a bird's eye view of the practice of adolescent health and medicine in India. PMID:27447203

Twenty 12-17 year olds were asked to narrate their own life stories using the life history narrative research method. Holistic content analysis was coupled with a grounded-theory approach to explore these data. Intergenerational responsibility, family tensions, economic pressures, racism and violence emerged without prompting and dominated the narrators' life stories, underscoring the degree to which these adolescents lack access to the supportive individuals and structures that are key to positive adolescent development. The challenges faced by these and the other 5.8 million 10-19 year olds in Peru require increased attention to the role of families, peers and communities in ensuring that adolescents are able to maintain their well-being and achieve their future expectations.

    Until the 1960s, few adolescents and young adults (AYAs) survived their initial cancer diagnoses. Now, ∼12,400 AYA patients are diagnosed with cancer each year, and almost 80% will now achieve a long-term cure. This dramatic improvement in survival is primarily due to multimodal treatments and combined chemotherapeutic regimens. Unfortunately, the increase in survival is often accompanied by treatment-related toxicities due to chemotherapy, radiation therapy, and surgical procedures. Despite guidelines published by the American Society of Clinical Oncology and numerous other professional organizations, high percentages of male AYA oncology patients are not properly counseled regarding their fertility preservation options before cancer treatment. Although administering fertility preservation care to adolescent males can be challenging in many ways, numerous studies show that this care can be delivered with high degrees of success and high levels of patient and parent satisfaction. The key to this success at many institutions has been the implementation of formalized integrated fertility preservation programs with infrastructure geared toward the delivery of comprehensive expedited care.

    2005-09-01

    Dextromethorphan hydrobromide (DXM), a constituent of more than 125 patent cough/cold remedies, is the most popular antitussive medication in the United States. Cough syrups or capsules also contain additional ingredients such as acetaminophen, chlorpheniramine maleate, guaifenesin, and/or pseudoephedrine, and toxicity with overdosage is additive to that of dextromethorphan alone. An unknown number of adolescents in the United States and Europe intoxicate themselves with acute megadoses of dextromethorphan. A megadose of DXM is defined as 5 to 10 times the dose recommended for control of annoying nonproductive coughs. Although a moderate overdose of pure DXM hydrobromide is free of serious adverse effects, approximately 5% of persons of European ethnicity lack the ability to metabolize the drug normally, leading to rapid acute toxic levels. Variable quantities of pure dextromethorphan powder in multiples of 1 gram are easily available from the worldwide web, including e-Bay. Recipe-like extraction procedures are quickly available on the Internet for seemingly simple and inexpensive home manufacture of concentrated dextromethorphan powder from Coricidin HBP Cough & Cold tablets (street name triple C). Adolescents intoxicate themselves at parties and even before or after school since the drug is legal, relatively inexpensive, and easily purchased or shoplifted at drug or convenient stores. Acute megadoses of the drug have profound psychological and physiological effects similar to those of phencyclidine (PCP). Megadoses of dextromethorphan used to self-intoxicate, can produce a false-positive screening test for phencyclidine in a urine specimen.

    2011-12-01

    Athletes active in endurance sports are at an increased risk of acquiring asthma through their sports activities, especially so for cross-country skiers, biathlon skiers, swimmers and athletes of other endurance sports. Asthma may be present from early childhood or develop while in active sports. This article focuses on the physical activity and sports activities in children and adolescents. Exercise-induced asthma (EIA) is found in 8-10% of a normal child population of school age and in about 35% of children with current asthma. EIA is caused by the markedly increased ventilation during exercise, with increased heat and water loss through respiration, leading to bronchial constriction. The risk of developing asthma in the young athlete is related to the repeated daily training activity with increased epithelial damage of the airways, delayed repair due to the daily repetition of the training and increased airway mucosal inflammation. The increased environmental exposure through the sports activity to environmental agents, such as cold, dry air in skiers and chlorine compounds in swimmers, increases symptoms and signs of asthma and bronchial hyper-responsiveness, either worsening an existing asthma or leading to a novel disease in a previously healthy athlete. Several specific aspects of daily training life, environmental exposure, diagnostic procedures and aspects of treatment related to the regulations of medication use in sports need particular attention when addressing the adolescent athlete with respiratory symptoms.

    The purpose of this study was to describe the experiences of individuals who survived the loss of one or both parents through parental homicide or homicide/suicide as adolescents. Participants (N = 34) were aged between 12 and 19 years at the time of the death and were aged between 29 and 64 years at the time of the interview. Participants were interviewed twice and asked to tell the story of their lives. Data were analyzed in the hermeneutic phenomenological tradition using a stepwise process of developing categories and then a single complex theme. Common categories of participants' childhoods included abuse both before and after the uxoricide and vivid memories of the homicide. As adults, most participants reported difficulties with intimate relationships, legal problems, and substance use. Integrity was an overarching theme for these participants. Among those who had integrated the story of the homicide into their adult lives, some believed that they were doing well whereas others did not. Some participants had isolated the event and considered that they were doing well as a result. These findings are limited by the convenience sample but offer a rich portrait of the lives of individuals who experienced uxoricide as adolescents. Clinicians might be advised to tread carefully if individuals report that they have isolated rather than integrated the uxoricide into their adult lives. No evidence exists in support that either stance is preferable.

    Data on national trends of sex behavior indicate that adolescents in the US are initiating sexual activity at younger ages than in the past several decades. The 1996 Centers for Disease Control Youth Behavior Survey found that 36.9% of 9th graders and 66.4% of 12th graders had been sexually active. Of those, 37.9% were sexually active within the 3 months preceding the survey. 12.7% of the sexually active boys and 4.9% of the sexually active girls reported beginning sexual activity before age 13 years. 72% of individuals aged 15-17 years and 84% of those aged 18-19 report using some form of contraception. However, many use contraception inconsistently. The most popular and effective methods of contraception chosen by adolescents are condoms, oral contraception, and depot medroxyprogesterone acetate (DMPA). These methods are discussed. Before either oral contraceptive pill or DMPA use is initiated, a detailed health history should be taken and a complete physical examination conducted which includes a pelvic examination.

    Health care professionals must be alert to the high prevalence of low adherence to treatment during adolescence. Low adherence increases morbidity and medical complications, contributes to poorer quality of life and an overuse of the health care system. Many different factors have an impact on adherence. However, critical factors to consider in teens are their developmental stage and challenges, emotional issues and family dysfunction. Direct and indirect methods have been described to assess adherence. Eliciting an adherence history is the most useful way for clinicians to evaluate adherence, and could be the beginning of a constructive dialogue with the adolescent. Interventions to improve adherence are multiple – managing mental health issues appropriately, building a strong relationship, customizing the treatment regimen if possible, empowering the adolescent to deal with adherence issues, providing information, ensuring family and peer support, and motivational enhancement therapy. Evaluation of adherence at regular intervals should be an important aspect of health care for adolescents. PMID:19119348

    Despite recent improvements in rates of teen pregnancy, abortion, birth,and contraceptive use, effective contraceptive counseling for adolescents should be a high priority for the primary care provider in the office setting. Adolescent psychosocial risk screening and appropriate counseling about sexual decision-making is necessary. Contraceptive services visits include, relevant history, limited physical examination, provision of information, anticipatory guidance about sexual behaviors, and the provision of contraceptive methods. Teens should always be encouraged to use a male condom during sex to reduce STI risk. A variety of barrier and hormonal contraceptive methods are available for the adolescent population. Education about and provision of EC is effective in reducing the rate of unintended pregnancy and abortion in the United States. Contraceptive care for adolescents is a rewarding experience for primary care providers.

    Adolescents are at a greater risk of being involved in traffic accidents than most other age groups, even before they start driving cars. This article aims to determine the factor structure of a self-report questionnaire measuring adolescent risky cycling behaviour, the ACBQ (Adolescent Cycling Behaviour Questionnaire). The questionnaire's structure was based on the widely used Driver Behaviour Questionnaire (DBQ). A sample of secondary school students (N = 1749; age range: 13-18 years) filled out the questionnaire. Factor analysis revealed a three-factor structure underlying the questionnaire, which was confirmed on two equally large portions of the entire sample. These three underlying factors were identified as errors, common violations and exceptional violations. The ACBQ is a useful instrument for measuring adolescents' risky cycling behaviour.

    It is unclear why children of adolescent mothers experience more developmental problems than children of adult mothers. There has been minimal systematic investigation of whether there is a relationship between the young age of the mother and her mothering behaviors. Our data fail to demonstrate any relationship between adolescent maternal age and the counts of maternal behaviors three days following birth. Seventy-five normal primiparous mothers less than 20 years old were videotaped with their normal infants for ten minutes in a standardized laboratory setting during the three days following birth. The frequency of maternal behaviors was counted from the videotapes by trained observers. Future studies of primiparous adolescent mothers should consider the effects of maternal race/culture and socioeconomic status on their mothering behaviors. The relationship between adolescent maternal age and the vocalizations expressed by the mother to her infant should also be explored further.

    Despite growing concern over the treatment of adolescents with psychiatric medications, little research has examined youth understandings and interpretations of mental illness and psychotropic treatment. This article reports the exploratory findings of semi-structured and open-ended interviews carried out with 20 adolescents diagnosed with one or more psychiatric disorders, and who were currently prescribed psychiatric medications. Grounded theory coding procedures were used to identify themes related to adolescent subjective experience with psychiatric medications. The categories identified are interpreted as different points of view through which adolescents understand and take action upon their illness concerns; their need for medication treatment; their perceptions of how medications work; their responses to parental and other influences upon medication treatment; and, their everyday management activities.

  1. Adolescent sexuality and public policy.

    In recent decades, various attempts have been made to determine the level of sexual activity among adolescents. This information has been used in the planning and evaluation of sex-related programs. However, there is a flaw in using only the initial estimates of the behavior--that a sexually active person is defined as one who has had sexual intercourse. This narrow definition distorts the perception of adolescent sexual behavior. Sexual activity can more accurately be designated by focusing on the actual frequency with which teenagers have sex. In this research report, adolescents were considered sexually active if they had had sex within the last four weeks. Using this definition, adolescents were found to be substantially less sexually active than has been previously reported. This finding was then used to look at various policy decisions in the areas of sex education, family planning, and sexually transmitted disease prevention. PMID:1927672

    The ethical and legal obligations with respect to treating a minor can be confusing, particularly in the areas of consent to treatment, confidentiality, and parental involvement. The clinician must be aware of the appropriate course of practice when the patient is an adolescent seeking care for contraception, pregnancy, or sexually transmitted infections. This article examines a number of ethical and legal issues that arise when providing reproductive and sexual health care to an adolescent and offers recommendations for the physician's most appropriate courses of action regarding adolescent patients and the age of consent to sexual activity, reporting of child abuse, provision of reproductive and sexual health care to a minor, assessing an adolescent's capacity to consent to treatment, the physician's duty of confidentiality, and the exceptions to the rule of confidentiality.

    Substance use during pregnancy may be a key mediator of the association between adolescent childbearing and poor newborn outcome. Substance use during pregnancy was evaluated for 50 teens who were consecutive patients at an inner-city university clinic. Although teens reported typical lifetime rates of substance use, self-reports and two urine assays indicated minimal substance use throughout pregnancy. Findings suggest that the adolescents exercised judicious decision making in light of the known health risks of substance use during pregnancy.

    WHO defines adolescence age between 10 to 19 years. In India, there are 243 million adolescents which constitute 21 per cent of the total population. The global burden of disease in adolescents (2011) reports that the total number of disability adjusted life years (DALYs) worldwide among adolescents were 230 million which constitutes 15.5% of total DALYs. The immunization is one of the most important, most beneficial and cost-effective disease prevention measures that can be provided for adolescents. The adolescent vaccination protects most of the world's adolescents from a number of infectious diseases that previously claimed millions of lives each year. In India, thousands of adolescents die and thousands are hospitalized every year due to communicable diseases that could have been prevented by vaccination. Main aims of adolescent vaccinations are: to boost immunity status that is waning after completion of primary immunization or absence of “natural” boosting due exposure to the particular disease. The recommendations for the immunization of adolescents are to improve vaccination coverage among them. The adolescent vaccinations also help in accelerate disease control or elimination effort. Improvement in adolescent immunization coverage in India, will require strengthening of health care delivery system and also require significant improvements in the health care functionaries ability and willingness to provide and deliver vaccines to adolescents.

    2015-04-01

    Heavy cannabis use has been frequently associated with increased rates of mental illness and cognitive impairment, particularly amongst adolescent users. However, the neurobiological processes that underlie these associations are still not well understood. In this review, we discuss the findings of studies examining the acute and chronic effects of cannabis use on the brain, with a particular focus on the impact of commencing use during adolescence. Accumulating evidence from both animal and human studies suggests that regular heavy use during this period is associated with more severe and persistent negative outcomes than use during adulthood, suggesting that the adolescent brain may be particularly vulnerable to the effects of cannabis exposure. As the endocannabinoid system plays an important role in brain development, it is plausible that prolonged use during adolescence results in a disruption in the normative neuromaturational processes that occur during this period. We identify synaptic pruning and white matter development as two processes that may be adversely impacted by cannabis exposure during adolescence. Potentially, alterations in these processes may underlie the cognitive and emotional deficits that have been associated with regular use commencing during adolescence. PMID:25460036

  15. Adolescents' information management: comparing ideas about why adolescents disclose to or keep secrets from their parents.

    PubMed

    2014-05-01

    Recognizing that adolescents providing or withholding information about their activities is a strong predictor of parental knowledge, this article compares several ideas about what prompts adolescents to disclose information or keep secrets from their parents. Using a sample of 874 Northern European adolescents (aged 12-16 years; 49.8 % were girls), modified cross-lagged models examined parental monitoring (solicitation and monitoring rules), adolescent delinquency, and perceived parental support as predictors and consequences of adolescents disclosing to parents or keeping secrets, with adolescents' acceptance of parental authority as a moderator. Results suggest that, when adolescents view their parents as supportive, they subsequently disclose more and keep fewer secrets. Engaging in delinquent behavior was related reciprocally to keeping secrets. By comparison, the results generally did not support the idea that adolescents who are monitored provide information to parents, even when they accept parental authority. These results suggest that relationship dynamics and adolescents' delinquent behaviors play an important role in adolescents' information management.

    The present study examined longitudinal acculturation patterns, and their associations with family functioning and adolescent risk behaviors, in Hispanic immigrant families. A sample of 266 Hispanic adolescents (mean age 13.4) and their primary parents completed measures of acculturation, family functioning, and adolescent conduct problems, substance use, and sexual behavior at five timepoints. Mixture models yielded three trajectory classes apiece for adolescent and parent acculturation. Assimilated adolescents reported the poorest family functioning, but adolescent assimilation negatively predicted adolescent cigarette smoking, sexual activity, and unprotected sex indirectly through family functioning. Follow-up analyses indicated that discrepancies between adolescent and parent family functioning reports predicted these adolescent outcomes. Results are discussed regarding acculturation trajectories, adolescent risk behavior, and the mediating role of family functioning. PMID:23848416

  17. Gender norms affect adolescents.

    PubMed

    Barnett, B

    1997-01-01

    Gender roles of men and women are determined by the society they live in. Many organizations that work with adolescents and young adults are incorporating a gender perspective into sex education, service delivery, and provider training programs in order to improve the reproductive health of their target groups. Many societies place a higher value on males than females. In sub-Saharan African countries girls are expelled from school if they become pregnant. In Egypt 86% of 2300 women interviewed believed the beatings by husband are justified under some circumstances, and 31% reported being beaten during pregnancy. A study of 128 adolescents in Peru and 108 in Columbia found that 60% of them had been sexually abused within the previous year. Female circumcision jeopardizes reproductive health, yet some 2 million girls undergo the procedure annually. In Thailand, among more than 100 factory workers 15-24 years old, the majority of men said premarital intercourse was accepted, while young women said premarital intercourse was unacceptable. Many programs that incorporate gender have begun projects that empower girls. Better Life Options administered by the Center for Development and Population Activities (CEDPA) provides information about sexuality, reproductive health, family planning and communication skills. The Young Men's Clinic, located in New York, aims to provide reproductive health services for men while also doing screening for tuberculosis or sickle-cell anemia. A report from the United Nations Population Fund states that men's services can be provided by minor adaptations to existing facilities. In Argentina the Foundation for Study and Research on Women offers education sessions on family planning and STDs to 50-100 secondary school students. In Gujarat, India, the Center for Health Education, Training and Nutrition Awareness incorporates gender into its health education workshops for young people ages 11-18. In these programs more equality in gender roles

But the tendency of intoxication is changing with some factors, such as national surveillance system, Naderism and increasing concern among physicians. But the death rate of intoxication among adolescents is increasing in spite of decreasing total death rate of intoxication among children and adolescents. Therefore the physician must be concerned about the basic management of intoxication and figure out the common toxic substance among children and adolescents. PMID:24511519

    2011-01-01

    The aim of this study was to explore the association between parental divorce and adolescent drunkenness and the contribution of adolescents' feelings toward their parents to this association. Cross-sectional data on 3,694 elementary school students from several cities in Slovakia (mean age 14.3, 49.0% males; response rate 93%) were obtained. Respondents completed questionnaires on how often they had been drunk in the previous 4 weeks, whether their parents were divorced and a measure of their feelings toward their parents. Parental divorce was found to have an effect on adolescent drunkenness in the previous month, as were the high rates of negative and low rates of positive feelings toward both parents. The effect of divorce on drunkenness strongly decreased if adjusted for the affect of the adolescent toward the father, but not the mother. Our findings indicate that to keep the father positively involved after divorce might be a protective factor with regard to a higher probability of adolescent drunkenness in divorced families.

    Background Adolescent suicide attempts are disproportionally prevalent and frequently of low severity, raising questions regarding their long-term prognostic implications. In this study, we examined whether adolescent attempts were associated with impairments related to suicidality, psychopathology, and psychosocial functioning in adulthood (objective 1) and whether these impairments were better accounted for by concurrent adolescent confounders (objective 2). Method 816 adolescents were assessed using interviews and questionnaires at four time points from adolescence to adulthood. We examined whether lifetime suicide attempts in adolescence (by T2, mean age 17) predicted adult outcomes (by T4, mean age 30) using linear and logistic regressions in unadjusted models (objective 1) and adjusting for sociodemographic background, adolescent psychopathology, and family risk factors (objective 2). Results In unadjusted analyses, adolescent suicide attempts predicted poorer adjustment on all outcomes, except those related to social role status. After adjustment, adolescent attempts remained predictive of axis I and II psychopathology (anxiety disorder, antisocial and borderline personality disorder symptoms), global and social adjustment, risky sex, and psychiatric treatment utilization. However, adolescent attempts no longer predicted most adult outcomes, notably suicide attempts and major depressive disorder. Secondary analyses indicated that associations did not differ by sex and attempt characteristics (intent, lethality, recurrence). Conclusions Adolescent suicide attempters are at high risk of protracted and wide-ranging impairments, regardless of the characteristics of their attempt. Although attempts specifically predict (and possibly influence) several outcomes, results suggest that most impairments reflect the confounding contributions of other individual and family problems or vulnerabilites in adolescent attempters.
