    Osteoporosis is a metabolic disease that is increasing in prevalence as people live longer. Because the orthopedic surgeon is frequently the first and often the only physician to manage patients with osteoporotic hip fractures, every effort should be made to prevent future fractures. A multidisciplinary approach is essential in treatment of osteoporotic fractures. Basic treatment includes calcium and vitamin D supplementation, fall prevention, hip protection, and balance and exercise programs. Currently available pharmacologic agents are divided into antiresorptive and anabolic groups. Antiresorptive agents such as bisphosphonates limit bone resorption through inhibition of osteoclastic activity. Anabolic agents such as parathyroid hormone promote bone formation.

    A common manifestation of age-related bone loss and resultant osteoporosis are fractures of the hip. Age-related osteoporosis is thought to be determined by a number of intrinsic factors including genetics, hormonal changes, changes in levels of oxidative stress, or an inflammatory status associated with the aging process. The aim of this study was to investigate gene expression and bone architecture in bone samples derived from elderly osteoporotic women with hip fractures (OP) in comparison to bone samples from age matched women with osteoarthritis of the hip (OA). Femoral heads and adjacent neck tissue were collected from 10 women with low-trauma hip fractures (mean age 83±6) and consecutive surgical hip replacement. Ten bone samples from patients undergoing hip replacement due to osteoarthritis (mean age 80±5) served as controls. One half of each bone sample was subjected to gene expression analysis. The second half of each bone sample was analyzed by microcomputed tomography. From each half, samples from four different regions, the central and subcortical region of the femoral head and neck, were analyzed. We could show a significantly decreased expression of the osteoblast related genes RUNX2, Osterix, Sclerostin, WNT10B, and Osteocalcin, a significantly increased ratio of RANKL to Osteoprotegerin, and a significantly increased expression of the enzymes superoxide dismutase 2 (SOD2) and glutathione peroxidase GPX3, and of the inflammatory cytokine IL6 in bone samples from hip fracture patients compared to controls. Major microstructural changes in OP bone were seen in the neck and were characterized by a significant decrease of bone volume, trabecular number, and connectivity density and a significant increase of trabecular separation. In conclusion, our data give evidence for a decreased expression of osteoblast related genes and increased expression of osteoclast related genes. Furthermore, increased expression of SOD2 and GPX3 suggest increased

    A prospective study was conducted among osteoporotic hip fracture in 2008. It was aimed to assess cost per quality adjusted life year (QALY) of hip fracture in the context of a developing country. The patients who were diagnosed as hip fracture and admitted to the orthopedic wards were included. Any pathological fractures or missing data were discarded from the analysis. Median cost was evaluated from a societal perspective. EQ-5D was used to assess health utility state and then converted into a time trade off Cost per QALYwas estimated at one year of follow-up. Forty-two patients completed a quality of life assessment. The average age was 75.6 years old and 71% were female. Most of them were undergone either hemiarthroplasty or internal fixation. The median total cost per year was US$ 4,210.60. The median QALY was 0.636 and cost per QALY was US$ 6,620.52. Cost utility of a hip fracture in Thai setting was lower than other developed countries due to strong family support and insufficient rehabilitation. However it has high impact on 78.8% of the Thai Gross National Product. Prevention of hip fracture is needed in underdeveloped countries as much as others, worldwide. PMID:26529817

    Background Proximal femoral geometry may be a risk factor of osteoporotic hip fractures. However, there existed great differences among studies depending on race, sex and age of subjects. The purpose of the present study is to analyze proximal femoral geometry and bone mineral density (BMD) in the osteoporotic hip fracture patients. Furthermore, we investigated proximal femoral geometric parameters affecting fractures, and whether the geometric parameters could be an independent risk factor of fractures regardless of BMD. Methods This study was conducted on 197 women aged 65 years or more who were hospitalized with osteoporotic hip fracture (femur neck fractures ; 84, intertrochanteric fractures; 113). Control group included 551 women who visited to check osteoporosis. Femur BMD and proximal femoral geometry for all subjects were measured using dual energy X-ray absorptiometry (DXA), and compared between the control and fracture groups. Besides, proximal femoral geometric parameters associated with fractures were statistically analyzed. Results There were statistically significant differences in the age and weight, cross-sectional area (CSA)/length/width of the femoral neck and BMD of the proximal femur between fracture group and control group. BMD of the proximal femur in the control group was higher than in the fracture group. For the femoral neck fractures group, the odds ratio (OR) for fractures decrease in the CSA and neck length (NL) of the femur increased by 1.97 times and 1.73 times respectively, regardless of BMD. The OR for fractures increase in the femoral neck width increased by 1.53 times. In the intertrochanteric fracture group, the OR for fractures increase in the femoral neck width increased by 1.45 times regardless of BMD. Conclusions We found that an increase of the femoral neck width could be a proximal femoral geometric parameter which plays important roles as a risk factor for fracture independently of BMD.

    Several common age-related mechanisms and factors influence muscle and bone, affecting functionality of both tissues. Sarcopenia is closely linked with osteoporosis, and their combined effect may exacerbate negative health outcomes. Fall-related fractures are some of the most serious consequences of these two systemic pathologies, with hip fracture being a major complication affecting osteoporotic and sarcopenic elderly. This work aims to review the literature on the current state of knowledge about the relations between sarcopenia and osteoporosis and to present the association between sarcopenia and osteoporosis and the risk of hip fracture. A literature search was performed in PubMed and Scopus databases for articles with the predefined terms "sarcopenia," "muscular atrophy," "femoral fractures," "hip fractures," "osteoporosis," and "bone density." There is a growing and significant interest being directed to sarcopenia and associated risk for osteoporotic hip fracture, but there still is a notorious heterogeneity in the methodology and cohort size of the available studies. Collectively, most of the studies herein analyzed indicate that sarcopenia could be a predictor of risk for hip fracture. The simultaneous evaluation of sarcopenia and osteoporosis may be of importance in identifying those patients in higher risk of suffering an osteoporotic hip fracture and who could benefit from preventive or therapeutic interventions, or both.

    Objective: To explore the relationship between tea drinking habits and osteoporotic hip/femur fractures. Methods: Paired case-control method was used for face-to-face interviews from January 2010 to June 2014. Patients (n=435) with newly osteoporotic hip/femur fracture and 435 controls with the same gender and age (±3) were given questionnaire survey. The survey content included general situation, detailed tea drinking and other diet condition, health-related behavior and family history of fractures, etc. Results: Single factor logistic analysis showed that the habit of drinking tea can significantly reduce the risk of hip/femur fracture. Cumulative year of tea drinking, the cumulative amount of tea and tea concentration (low dose group) have the maximum protection for fracture, while the high dose group is weaker in protection (trend test, P<0.05). After adjustment for age, energy, BMI, education degree, parents’ history of fracture, second hand smoke exposure, calcium supplements, and equivalent energy consumption of physical activity, etc, the above association still showed significant linear trend, but the associated strength was slightly reduced. But stratified analysis found that the effect of tea drinking was only statistically significant in men. And there were no statistically significant differences of people with different education degree. Conclusions: Regular tea drinking can reduce the risk of osteoporotic hip/femur fractures in middle-aged and elderly men. PMID:27182250

    The role of antioxidant intake in osteoporotic hip fracture risk is uncertain and may be modified by smoking. In the Utah Study of Nutrition and Bone Health, a statewide, population-based case-control study, the authors investigated whether antioxidant intake was associated with risk of osteoporotic hip fracture and whether this association was modified by smoking status. The analyses included data on 1,215 male and female cases aged > or = 50 years who incurred a hip fracture during 1997-2001 and 1,349 age- and sex-matched controls. Diet was assessed by food frequency questionnaire. Among ever smokers, participants in the highest quintile of vitamin E intake (vs. the lowest) had a lower risk of hip fracture after adjustment for confounders (odds ratio = 0.29, 95% confidence interval (CI): 0.16, 0.52; p-trend < 0.0001). The corresponding odds ratio for beta-carotene intake was 0.39 (95% CI: 0.23, 0.68; p-trend = 0.0004), and for selenium intake it was 0.27 (95% CI: 0.12, 0.58; p-trend = 0.0003). Vitamin C intake did not have a significant graded association with hip fracture risk among ever smokers. Similar findings were obtained when an overall antioxidant intake score was used (odds ratio = 0.19, 95% CI: 0.10, 0.37; p-trend < 0.0001). No similar associations were found in never smokers. Antioxidant intake was associated with reduced risk of osteoporotic hip fracture in these elderly subjects, and the effect was strongly modified by smoking status. PMID:16306312

    Background Calcaneal quantitative ultrasound (QUS), which is used in the evaluation of osteoporosis, is believed to be intimately associated with the characteristics of the proximal femur. However, the specific associations of calcaneal QUS with characteristics of the hip sub-regions remain unclear. Design A cross-sectional assessment of 53 osteoporotic patients was performed for the skeletal status of the heel and hip. Methods We prospectively enrolled 53 female osteoporotic patients with femoral fractures. Calcaneal QUS, dual energy X-ray absorptiometry (DXA), and hip structural analysis (HSA) were performed for each patient. Femoral heads were obtained during the surgery, and principal compressive trabeculae (PCT) were extracted by a three-dimensional printing technique-assisted method. Pearson’s correlation between QUS measurement with DXA, HSA-derived parameters and Young’s modulus were calculated in order to evaluate the specific association of QUS with the parameters for the hip sub-regions, including the femoral neck, trochanteric and Ward’s areas, and the femoral shaft, respectively. Results Significant correlations were found between estimated BMD (Est.BMD) and BMD of different sub-regions of proximal femur. However, the correlation coefficient of trochanteric area (r = 0.356, p = 0.009) was higher than that of the neck area (r = 0.297, p = 0.031) and total proximal femur (r = 0.291, p = 0.034). Furthermore, the quantitative ultrasound index (QUI) was significantly correlated with the HSA-derived parameters of the trochanteric area (r value: 0.315–0.356, all p<0.05) as well as with the Young’s modulus of PCT from the femoral head (r = 0.589, p<0.001). Conclusion The calcaneal bone had an intimate association with the trochanteric cancellous bone. To a certain extent, the parameters of the calcaneal QUS can reflect the characteristics of the trochanteric area of the proximal hip, although not specifically reflective of those of the femoral neck

    Hip fractures are an acute and worsening public health problem. They mainly affect elderly people, a population group that is highly vulnerable to disease and accidents, and to falls in particular. Although it has been suggested that osteoporosis is the cause of hip fractures, they mainly occur after a fall has been suffered. The underlying causes of a fall are not related to osteoporosis, although pharmaceutical companies have coined the term “osteoporotic fracture” for hip fractures in the elderly. Drug treatments for osteoporosis have not diminished the frequency of these injuries, nor have they prevented the occurrence of a subsequent fracture. Since pharmaceutical interests require osteoporosis to be considered a disease, rather than a normal condition of senescence, they go further by assuming that treatment for osteoporosis is essential, and that this policy will diminish the incidence of hip fractures. On the other hand, the origin and treatment of conditions that may be conducive to provoking falls are very difficult to elucidate. In this paper, we consider some of the medical and social problems that arise in this area, as well as conflicts of interest regarding the aetiopathogenesis and prevention of hip fracture, and propose a new paradigm for the prevention of falls.

    Numerous high quality studies have shown the positive effects of various osteoporotic medical treatment regimens on bone mass and on the reduction of risk for new spinal, hip and non-spinal fractures in osteoporotic patients. However, the effect of osteoporotic treatment on the functional and clinical outcome of patients who have sustained hip fractures and been treated surgically has not yet been addressed. Five hundred and twenty patients out of 611 who were admitted (2009-2011), operated on due to a hip fracture and completed their follow-up evaluations were included in this study. Data related to functional outcome scores, re-fracture rate, quality of life and mortality rate were prospectively recorded, analysed and correlated to osteoporotic medical treatment. There were 151 (25%) men and 369 (71%) women with a mean age of 80.7 years (range, 60 to 90 years). At a mean follow-up of 27.5 months (range, 24 to 36 months) a mortality rate of 23.6% at 2 years was recorded. Mean values of functional and quality of life scores were found to have progressively improved within two years after surgery. Seventy-eight (15%) patients were taking osteoporotic treatment before their hip fracture and 89 (17.1%) started afterwards. Osteoporotic treatment proved to be an important predictor of functional recovery (all p values<0.05), re-fracture rate (p=0.028) and quality of life (EQ-5D, all dimensions, p values<0.05). Osteoporotic treatment did not affect post-fracture mortality rates. Osteoporotic treatment taken before or initiated after fracture is a strong predictor of functional and clinical outcome in patients with hip fractures treated surgically. PMID:25541417

    Weekly administration of teriparatide has been shown to reduce the risk of vertebral and non-vertebral fractures in patients with osteoporosis at higher fracture risk in Japan. However, its efficacy for hip fracture has not been established. To gain insight into the effect of weekly teriparatide on the hip, hip structural analysis (HSA) based on dual-energy X-ray absorptiometry (DXA) was performed using the data of 209 postmenopausal osteoporotic women who had participated in the original randomized, multicenter, double-blind, placebo-controlled trial assessing the effects of once-weekly 56.5 μg teriparatide for 72 weeks. The DXA scans, obtained at baseline, 48 weeks and 72 weeks, were analyzed to extract bone mineral density (BMD) and cross-sectional geometrical indices at the narrowest point on the neck (NN), the intertrochanteric region (IT), and the proximal shaft. Compared with placebo after 72 weeks, the teriparatide group showed significantly higher BMD, average cortical thickness, bone cross-sectional area, and section modulus, and lower buckling ratio at both the NN and IT regions. No significant expansion of periosteal diameter was observed at these regions. There were no significant differences in BMD and HSA indices at the shaft region. The results indicate that overall structural strength in the proximal femur increased compared to placebo, suggesting that once-weekly teriparatide effectively reverses changes in hip geometry and strength with aging.

    Backgrounds The number of hip fractures, the most common complication of osteoporosis, has increased rapidly over the past decades. The goal of this study is to estimate the avoidable burden of certain modifiable risk factor of the condition using the Generalized Impact Fraction (GIF) model, which has been suggested and used by epidemiologists to overcome the drawbacks associated with the use of Attributable Fraction index. In addition to preventing a risk factor or the avoidable fraction of burden, this index can also calculate the change in the burden, when a risk factor is altered. Methods International databases were searched through PubMed, CINAHLD, Embase using OVID and Google scholar. National resources were searched through IranDoc, IranMedex, SID and Journal sites. Other resources include abstract books and articles sent to the IOF congress. The following search strategy was used: (“Osteoporotic fracture” OR “Fragility Hip fracture” OR “Calcium” OR “vitamin D” OR “BMI” OR “lean body weight” OR “Physical activity” OR “exercise” OR “Smoke”) AND (“prevalence” OR “incidence” OR “relative risk”) and limited to “humans.” Results With regards to different scenarios already explained in modifying the studied risk factors, the greatest impact in reducing the prevalence of risk factors on osteoporotic hip fractures, was seen in low serum vitamin D levels, low physical activity and low intake of calcium and vitamin D, respectively. According to the fact that interventions for low serum vitamin D and low intake of calcium and vitamin D, are related to each other, it can be concluded that implementing interventions to change these two risk factors, in the easy, moderate and difficult scenarios, would result in approximately a 5%, 11% and 17% decrease in the burden of osteoporotic hip fractures, respectively. The addition of interventions addressing low physical activity in the easy, moderate and difficult scenarios

    Background Incidence rates of non-hip major osteoporotic fractures (MOF) remain poorly characterized in the Netherlands. The Dutch FRAX® algorithm, which predicts 10-year probabilities of hip fracture and MOF (first of hip, humerus, forearm, clinical vertebral), therefore incorporates imputed MOF rates. Swedish incidence rate ratios for hip fracture to MOF (Malmo 1987–1996) were used to perform this imputation. However, equality of these ratios between countries is uncertain and recent evidence is scarce. Aims were to estimate incidence rates of hip fracture and MOF and to compare observed MOF rates to those predicted by the imputation method for the Netherlands. Methods Using hospitalisation and general practitioner records from the Dutch PHARMO Database Network (2002–2011) we calculated age-and-sex-specific and age-standardized incidence rates (IRs) of hip and other MOFs (humerus, forearm, clinical vertebral) and as used in FRAX®. Observed MOF rates were compared to those predicted among community-dwelling individuals ≥50 years by the standardized incidence ratio (SIR; 95% CI). Results Age-standardized IRs (per 10,000 person-years) of MOF among men and women ≥50 years were 25.9 and 77.0, respectively. These numbers were 9.3 and 24.0 for hip fracture. Among women 55–84 years, observed MOF rates were significantly higher than predicted (SIR ranged between 1.12–1.50, depending on age). In men, the imputation method performed reasonable. Conclusion Observed MOF incidence was higher than predicted for community-dwelling women over a wide age-range, while it agreed reasonable for men. As miscalibration may influence treatment decisions, there is a need for confirmation of results in another data source. Until then, the Dutch FRAX® output should be interpreted with caution.

    As the world population rises, osteoporotic fracture is an emerging global threat to the well-being of elderly patients. The process of fracture healing by intramembranous ossification or/and endochondral ossification involve many well-orchestrated events including the signaling, recruitment and differentiation of mesenchymal stem cells (MSCs) during the early phase; formation of a hard callus and extracellular matrix, angiogenesis and revascularization during the mid-phase; and finally callus remodeling at the late phase of fracture healing. Through clinical and animal research, many of these factors are shown to be impaired in osteoporotic bone. Animal studies related to post-menopausal estrogen deficient osteoporosis (type I) have shown healing to be prolonged with decreased levels of MSCs and decreased levels of angiogenesis. Moreover, the expression of estrogen receptor (ER) was shown to be delayed in ovariectomy-induced osteoporotic fracture. This might be related to the observed difference in mechanical sensitivity between normal and osteoporotic bones, which requires further experiments to elucidate. In mice fracture models related to senile osteoporosis (type II), it was observed that chondrocyte and osteoblast differentiation were impaired; and that transplantation of juvenile bone marrow would result in enhanced callus formation. Other factors related to angiogenesis and vasculogenesis have also been noted to be impaired in aged models, affecting the degradation of cartilaginous matrixes and vascular invasion; the result is changes in matrix composition and growth factors concentrations that ultimately impairs healing during age-related osteoporosis. Most osteoporotic related fractures occur at metaphyseal sites clinically, and reports have indicated that differences exist between diaphyseal and metaphyseal fractures. An animal model that satisfies three main criteria (metaphyseal region, plate fixation, osteoporosis) is suggested for future research for

    With the population and proportion of the elderly increasing each year, difficulties with postoperative treatment outcomes after osteoporotic hip fracture are increasing. This study focused on activities of daily living (ADL) in patients who underwent surgery for hip fracture through an investigation of living arrangements, the presence of dementia, and other complications of aging. Information from 99 patients who lived either at home or in geriatric health service facilities was collected for this trial. Most patients were over 65 years of age and female, and about half of them had dementia. The postoperative ADL score (focusing on patients' walking ability) was significant for those living at home than for those living in facilities. In addition, patients with dementia were divided into the following two categories: an early-rising group, comprising patients who were able to use a wheelchair within 48 hours of their operation; and a late-rising group, who did not start using a wheelchair until more than 48 hours after surgery. The ADL scores for the two groups were compared. Although the preoperative ADL scores were not significantly different between the two groups, postoperative ADL scores were significantly higher in the early-rising group than in the late-rising group, especially in patients who had undergone hemiarthroplasty. These data suggest that ADL in dementia patients following hip fracture depends on the surgical procedure performed and whether they are late or early risers after surgery. PMID:25378917

    Osteoporotic fractures are difficult to manage. They pose a number of difficulties to the surgeon arising from the underlying poor bone stock compromising the intention to achieve optimum fixation. Moreover, the frail elderly patients present with a variety of medical co-morbidities increasing the risk of developing perioperative complications. Despite these recognized challenges, there are currently a number of improving technologies and strategies at the surgeon's disposal to provide more confidence with fracture fixation and maximize the chance of success.

    The heparin-binding growth and differentiation factor midkine (Mdk) is proposed to negatively regulate osteoblast activity and bone formation in the adult skeleton. As Mdk-deficient mice were protected from ovariectomy (OVX)-induced bone loss, this factor may also play a role in the pathogenesis of postmenopausal osteoporosis. We have previously demonstrated that Mdk negatively influences bone regeneration during fracture healing. Here, we investigated whether the inhibition of Mdk using an Mdk-antibody (Mdk-Ab) improves compromised bone healing in osteoporotic OVX-mice. Using a standardized femur osteotomy model, we demonstrated that Mdk serum levels were significantly enhanced after fracture in both non-OVX and OVX-mice, however, the increase was considerably greater in osteoporotic mice. Systemic treatment with the Mdk-Ab significantly improved bone healing in osteoporotic mice by increasing bone formation in the fracture callus. On the molecular level, we demonstrated that the OVX-induced reduction of the osteoanabolic beta-catenin signaling in the bony callus was abolished by Mdk-Ab treatment. Furthermore, the injection of the Mdk-Ab increased trabecular bone mass in the skeleton of the osteoporotic mice. These results implicate that antagonizing Mdk may be useful for the therapy of osteoporosis and osteoporotic fracture-healing complications. PMID:27410432

    Due to the increasing elderly population, the prevalence of osteoporotic hip fractures in Japanese patients continues to rise. It is well established that patients with either hip fracture or both symptomatic and asymptomatic morphometric vertebral compression fracture (VCF) have a poor health prognosis compared with the general population. The purpose of this study was to retrospectively investigate vertebral fracture rates among patients with hip fracture and their influence on mortality. We examined 182 cases of osteoporotic hip fracture in patients admitted to our institution between January 2009 and May 2011. The average age at the time of fracture was 85 years. Radiographs of the lumbar spine were obtained from all of the participants and the lateral spinal radiographs were examined for evidence of VCF. The patients were classified into two groups, those with VCF and those without. A VCF was identified in approximately 78 % of the patients. The mortality rate 1 year after the hip fracture was approximately 22 % and it was significantly higher in patients with VCF. Through multivariate statistics we found that VCF, post-operative complication, loss of ambulation after operation and medication for osteoporosis were statistically significant. In other words, VCF, post-operative complication and loss of ambulation were considered to be poor prognostic factors and medication for osteoporosis was likely to improve the prognosis. We concluded that the risk of mortality after hip fracture is significantly greater in patients who also have VCF compared to patients without VCF, and that medication for osteoporosis is likely to improve prognosis.

    Osteoporotic fractures are one of the most common causes of disability and a major contributor to medical care costs worldwide. Prior osteoporotic fracture at any site is one of the strongest risk factors for a new fracture, which occurs very soon after the first fracture. Bone mineral density (BMD) scan, a conventional diagnostic tool for osteoporosis, has clear limitations in diagnosing osteoporotic fractures and identifying the risk of subsequent fractures. Therefore, early and accurate diagnosis of osteoporotic fractures using the clinical definition which is applicable practically and independent of BMD, is essential for preventing subsequent fractures and reducing the socioeconomic burden of these fractures. Fractures caused by low-level trauma equivalent to a fall from a standing height or less at major (hip, spine, distal radius, and proximal humerus) or minor (pelvis, sacrum, ribs, distal femur and humerus, and ankle) sites in adults over age 50, should be first regarded as osteoporotic. In addition, if osteoporotic fractures are strongly suspected on history and physical examination even though there are no positive findings on conventional X-rays, more advanced imaging techniques such as computed tomography, bone scan, and magnetic resonance imaging are necessary as soon as possible.

    Osteoporosis is a silent disease without any evidence of disease until a fracture occurs. Approximately 200 million people in the world are affected by osteoporosis and 8.9 million fractures occur each year worldwide. Fractures of the hip are a major public health burden, by means of both social cost and health condition of the elderly because these fractures are one of the main causes of morbidity, impairment, decreased quality of life and mortality in women and men. The aim of this review is to analyze the most important factors related to the enormous impact of osteoporotic fractures on population. Among the most common risk factors, low body mass index; history of fragility fracture, environmental risk, early menopause, smoking, lack of vitamin D, endocrine disorders (for example insulin-dependent diabetes mellitus), use of glucocorticoids, excessive alcohol intake, immobility and others represented the main clinical risk factors associated with augmented risk of fragility fracture. The increasing trend of osteoporosis is accompanied by an underutilization of the available preventive strategies and only a small number of patients at high fracture risk are recognized and successively referred for therapy. This report provides analytic evidences to assess the best practices in osteoporosis management and indications for the adoption of a correct healthcare strategy to significantly reduce the osteoporosis burden. Early diagnosis is the key to resize the impact of osteoporosis on healthcare system. In this context, attention must be focused on the identification of high fracture risk among osteoporotic patients. It is necessary to increase national awareness campaigns across countries in order to reduce the osteoporotic fractures incidence. PMID:27004165

    Purpose Osteoporotic fracture is the main complication of osteoporosis. The current management is to discharge patients as early as possible so they can get back to their daily activities. Once discharged, there are three main issues relating to morbidity, mortality, and risk of a subsequent fracture that need to be addressed and discussed. Therefore, the aim of this systematic review was to summarize and evaluate the evidence from published literature, to determine the outcome of osteoporotic fracture patients after their hospital discharge. Methods The MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were searched, using the terms “osteoporosis”, “fracture”, “osteoporotic fracture”, “hip fracture”, and “vertebral fracture”. We included only human studies published in English between 2004 and 2014. The reference lists of included studies were thoroughly reviewed in search for other relevant studies. Results A total of 18 studies met the selection criteria. Most were observational and cohort studies. Out of all the studies, five studies looked into the morbidity, six studies looked into the risk of subsequent fractures, and seven studies looked into mortality. Vertebral fracture caused the greatest health burden, but hip fracture patients were the main users of informal care after hospital discharge. There was an increased risk of a subsequent fracture after a primary fracture compared with the control group, a cohort comparison, or the general population. Osteoporotic fractures, especially hip fractures, are associated with higher mortality rate despite the advances in the management of osteoporotic fracture cases. Conclusion There is strong evidence to show that after hospital discharge, osteoporotic fracture patients are faced with higher morbidity, subsequent fractures, and mortality. PMID:25429224

    Many orthobiologic adjuvants are available and widely utilized for general skeletal restoration. Their use for the specific task of osteoporotic fracture augmentation is less well recognized. Common conductive materials are reviewed for their value in this patient population including the large group of allograft adjuvants categorically known as the demineralized bone matrices (DBMs). Another large group of alloplastic materials is also examined-the calcium phosphate and sulfate ceramics. Both of these materials, when used for the proper indications, demonstrate efficacy for these patients. The inductive properties of bone morphogenic proteins (BMPs) and platelet concentrates show no clear advantages for this group of patients. Systemic agents including bisphosphonates, receptor activator of nuclear factor κβ ligand (RANKL) inhibitors, and parathyroid hormone augmentation all demonstrate positive effects with this fracture cohort. Newer modalities, such as trace ion bioceramic augmentation, are also reviewed for their positive effects on osteoporotic fracture healing. PMID:25431160

    There is little data concerning the morbidity, mortality, and epidemiology of vertebral fracture. The aim of this study was to evaluate the effect of prevalent and incident vertebral fractures as risk factors for further osteoporotic fractures and mortality. The study was performed on a cohort of 316 women and 308 men older than 50 belonging to the EVOS study, randomly selected from our city register. At the beginning of the study and 4 years later, lateral dorsal and lumbar X-rays were performed. In addition, evaluation of the incidence of osteoporotic nonvertebral fractures was performed throughout 8 years. The incidence of all osteoporotic fractures was higher in women than in men (two-fold increase in vertebral fracture incidence and five-fold increase in Colles' and femur incidence). Vertebral fracture was a strong risk factor for a new vertebral fracture [RR=4.7 (1.8-11.9)], hip fracture [RR=6.7 (2.0-22.7)] and Colles' fracture [RR=3.0 (1.1-7.8)]. Prevalent and incident vertebral fractures were associated with a higher risk of having a hip fracture [RR=10.0 (2.0-50.2)] and Colles' fracture [RR=5.5 (1.3-23.4)]. In addition, in women, the vertebral fracture was associated with a higher mortality. By contrast, no association was found in men. These results demonstrate the association between a previous vertebral fracture with increments in the incidence of osteoporotic fractures of any type. In addition, we found a significantly higher mortality rate in women having vertebral fractures. These findings support the necessity of preventing the occurrence of vertebral fractures to limit their strong negative impact on mortality. PMID:12730754

    Summary Fragility fractures of the femur are one of the major causes of morbidity and mortality worldwide. The incidence of new contralateral hip fractures in elderly osteoporotic patients ranges from 7 to 12% within 2 years after the first fracture. Secondary prevention can be divided in: pharmacological therapy based on the prescription of anti-osteoporotic drugs with different mechanism of action and non-pharmacological therapy which is based on modification of environmental risk factors, on a healthy diet with daily supplements of calcium and vitamin D and calcium and on the use of hip protectors. Recently a new form of prevention is becoming achievable: surgical prevention; the rationale of surgical reinforcement is the need to increase the resistance of the femoral neck to the compression and distraction forces acting on it. In this paper we analyse all the experimental and “on the market” device available for the surgical prevention of femoral neck fracture. PMID:27252744

    It is well known that the adoption of preventive measures for osteoporosis may contribute to minimizing its impact as a result of bone fractures. However, there are well-recognized risk factors involved in the onset of osteoporosis that are not possible to modify. Better knowledge of these non-modifiable factors could aid prevention in subjects at high risk of fractures. The aim of this study was to evaluate the likely association between gynecological, reproductive and family history of hip fracture with the incidence of vertebral and nonvertebral osteoporotic fractures in women older than 50. We studied 255 women aged 50 and over, randomly selected from a Spanish population that had participated in a study of prevalence of vertebral fractures (EVOS study). This cohort was prospectively followed for 8 years by means of four postal questionnaires, in order to find out the incidence of nonvertebral fractures. Concerning the incidence of vertebral fractures, participants were invited to repeat the lumbar spine X-rays 4 years after the initial study. A total of 31 women had incident osteoporotic fractures. The analysis of gynecological variables showed that an increase in the age at menarche was a risk factor for all incident osteoporotic fractures [OR=1.57 (1.04-2.37)]. The presence of amenorrhea at any age during the fertile period was associated with higher incidence of all osteoporotic fractures [OR=6.30 (1.61-24.70)]. Among all the reproductive variables analyzed (pregnancy, number of live births and breast-feeding) only pregnancy was an important protective factor in preventing incident Colles fracture [OR=0.15 (0.03-0.62)]. A family history of hip fracture was associated with a higher incidence of all osteoporotic fractures [OR=3.59 (1.01-12.79)]. In summary, a late age at menarche, the presence of amenorrhea and having close relatives with hip fracture were all risk factors which, independently of bone mineral density (BMD) and age, were associated with higher

    Despite improvements in implants and surgical techniques, osteoporotic fractures remain challenging to treat. Among other major risk factors, decreased expression of morphogenetic proteins has been identified for impaired fracture healing in osteoporosis. Bone grafts or bone graft substitutes are often used for stabilizing the implant and for providing a scaffold for ingrowth of new bone. Both synthetic and naturally occurring biomaterials are available. Products generally contain hydroxyapatite, tricalcium phosphate, dicalcium phosphate, calcium phosphate cement, calcium sulfate (plaster of Paris), or combinations of the above. Products have been used for the treatment of osteoporotic fractures of the proximal humerus, distal radius, vertebra, hip, and tibia plateau. Although there is generally consensus that screw augmentation increased the biomechanical properties and implant stability, the results of using these products for void filling are not unequivocal. In osteoporotic patients, Bone Morphogenetic Proteins (BMPs) have the potential impact to improve fracture healing by augmenting the impaired molecular and cellular mechanisms. However, the clinical evidence on the use of BMPs in patients with osteoporotic fractures is poor as there are no published clinical trials, case series or case studies. Even pre-clinical literature on in vitro and in vivo data is weak as most articles focus on the beneficial role for BMPs for restoration of the underlying pathophysiological factors of osteoporosis but do not look at the specific effects on osteoporotic fracture healing. Limited data on animal experiments suggest stimulation of fracture healing in ovariectomized rats by the use of BMPs. In conclusion, there is only limited data on the clinical relevance and optimal indications for the use of bone graft substitute materials and BMPs on the treatment of osteoporotic fractures despite the clinical benefits of these materials in other clinical indications.

    The human skeleton has the ability to modify its material composition and structure to accommodate loads through adaptive modelling and remodelling. The osteocyte cell network is now considered to be central to the regulation of skeletal homeostasis; however, very little is known of the integrity of the osteocyte cell network in osteoporotic fragility fracture. This study was designed to characterise osteocyte morphology, the extent of osteocyte cell apoptosis and expression of sclerostin protein (a negative regulator of bone formation) in trabecular bone from the intertrochanteric region of the proximal femur, for postmenopausal women with fragility hip fracture compared to age-matched women who had not sustained fragility fracture. Osteocyte morphology (osteocyte, empty lacunar, and total lacunar densities) and the degree of osteocyte apoptosis (percent caspase-3 positive osteocyte lacunae) were similar between the fracture patients and non-fracture women. The fragility hip fracture patients had a lower proportion of sclerostin-positive osteocyte lacunae in comparison to sclerostin-negative osteocyte lacunae, in contrast to similar percent sclerostin-positive/sclerostin-negative lacunae for non-fracture women. The unexpected finding of decreased sclerostin expression in trabecular bone osteocytes from fracture cases may be indicative of elevated bone turnover and under-mineralisation, characteristic of postmenopausal osteoporosis. Further, altered osteocytic expression of sclerostin may be involved in the mechano-responsiveness of bone. Optimal function of the osteocyte cell network is likely to be a critical determinant of bone strength, acting via mechanical load adaptation, and thus contributing to osteoporotic fracture risk.

    Hyponatremia may be a risk factor for fracture. To determine the relationship between hyponatremia and fracture we conducted cross-sectional and longitudinal analyses using data from the Osteoporotic Fractures in Men Study (MrOS). The MrOS study enrolled 5122 community dwelling men aged ≥ 65 years from six centers across the United States. We excluded men taking bisphosphonates, those with unknown medication history, those without serum sodium measures, or those with out of range assays for serum sodium. Serum sodium was measured at study entry. Subjects were followed for fractures (nonspine (including hip), hip, and incident and prevalent morphometric) for up to 9 years. We used cox proportional hazards models to analyze the association between serum sodium levels (<135mmol/L versus ≥135mmol/L) and risk of nonspine and hip fractures, with results presented as hazard ratios (HR) and 95% confidence intervals (CI). We examined the association between morphometric vertebral fractures and serum sodium using logistic regression models, presented as odds ratios (OR) and 95% CI. Hyponatremia was observed in 64 men (1.2% of the cohort). After adjusting for age, BMI, study center, and other covariates, we found that, compared to men with serum sodium ≥ 135mmol/L, those with serum sodium <135mmol/L, had an increased risk hip fracture (HR=3.04; 95% CI: 1.37 to 6.75), prevalent (OR=2.46; 95% CI: 1.22 to 4.95) and incident (OR=3.53; 95% CI: 1.35 to 9.19) morphometric spine fractures but not nonspine fractures (OR=1.44; 95% CI: 0.85 to 2.44). Adjusting for bone mineral density did not change our findings. Our data demonstrate that hyponatremia is associated with up to a doubling in the risk of hip and morphometric spine fractures, independent of BMD. Further studies, to determine how hyponatremia causes fractures and if correction of hyponatremia decreases fractures, are needed. PMID:25294595

    Osteoporosis is a common skeletal disorder characterized by increased risk of bone fracture (BF) due to fragility. BFs, particularly hip fracture, are a major concern in health care because of the associated morbidity and mortality, mainly in the elderly. Lately the involvement of epigenetic mechanisms in the pathophysiology of many diseases has been recognized. In this context, the identification of microRNAs (miRNAs) specific to BF should represent a substantial step forward in diagnostics and therapeutics. The present study aimed to identify specific miRNAs in osteoporotic BF patients compared to those in osteoarthritic controls. In the profiling stage, total RNA was extracted from serum, two pools were prepared, and then retro-transcribed in triplicate. Levels of 179 serum miRNAs were analyzed by real-time PCR, and 42 of them showed significance (P < 0.05), and 12 passed the false discovery rate test for multiple comparisons. Six miRNAs were selected for the replication stage and individually analyzed in sera from 15 BF patients and 12 controls. Results showed that 3 miRNAs (miR-122-5p, miR-125b-5p, and miR-21-5p) were valuable upregulated biomarkers in BF with respect to controls and, significantly, their levels were not affected by hemolysis. For miR-21-5p, the difference detected between groups was independent of age (P = 0.005) and its levels correlated to those of CTx (r = 0.76; P < 0.00001), a marker of bone resorption. In conclusion, several miRNAs may be biomarkers of BF, particularly miR-21-5p. Further studies are needed in order to better characterize the levels of these miRNAs in other bone diseases and to elucidate the mechanism involved in the association of these three miRNAs with osteoporotic BF.

    To examine the degree of trauma in major osteoporotic fractures (MOF) in men versus women, we used data from 15,698 adults aged ≥65 years enrolled in the Osteoporotic Fractures in Men (MrOS) study (5994 men) and the Study of Osteoporotic Fractures (SOF) (9704 women). Participants were contacted tri-annually to ascertain incident fractures, which were confirmed by radiographic reports and coded according to degree of self-reported trauma. Trauma was classified as low (fall from ≤ standing height; fall on stairs, steps, or curb; minimal trauma other than fall [coughing, turning over]); moderate (collisions with objects during normal activity without associated fall); or high (fall from > standing height; severe trauma [motor vehicle accident, assault]). MOF included hip, clinical vertebral, wrist, and humerus fractures. Mean fracture follow-up was 9.1 years in SOF and 8.7 years in MrOS. A total of 14.6% of the MOF in men versus 6.3% of the MOF in women were classified as high trauma (p < 0.001); men versus women more often experienced fractures resulting from severe trauma as well as from fall > standing height. High-trauma fractures were more significantly common in men versus women at the hip (p = 0.002) and wrist (p < 0.001) but not at the spine or humerus. Among participants with MOF, the odds ratio of a fracture related to high-trauma fracture among men versus women was 3.12 (95% confidence interval [CI] 1.70-5.71) after adjustment for traditional risk factors. Findings were similar in analyses limited to participants with hip fractures (odds ratio [OR] = 3.34, 95% CI 1.04-10.67) and those with wrist fracture (OR = 5.68, 95% CI 2.03-15.85). Among community-dwelling older adults, MOF are more likely to be related to high trauma in men than in women. These findings are not explained by sex differences in conventional risk factors and may reflect a greater propensity among men to engage in risky behavior. © 2015 American Society for Bone and Mineral Research

    Introduction It is unknown whether kyphosis of the thoracic spine is an independent risk factor for future osteoporotic fractures. Materials and Methods We conducted a prospective cohort study of 596 community-dwelling women, 47–92 years of age. Between 1988 and 1991, BMD of the hip and spine and kyphosis were measured. Kyphosis was measured by counting the number of 1.7-cm blocks necessary to place under the occiput so participants could lie flat without neck hyperextension. New fractures were reported over an average follow-up of 4 years. Results Using a cut-off of at least one block, 18% of the participants had hyperkyphotic posture (range, one to nine blocks). There were 107 women who reported at least one new fracture (hip, spine, wrist, clavicle, shoulder, arm, hand, rib, pelvis, leg, or ankle). In logistic regression analyses, older women with hyperkyphotic posture (defined as at least one block) had a 1.7-fold increased risk of having a future fracture independent of age, prior fracture, and spine or hip BMD (95% CI: 1.00–2.97; p = 0.049). There was a significant trend of increasing fracture risk with increasing number of blocks, with ORs ranging from 1.5 to 2.6 as the number of blocks increased from one to at least three blocks compared with those with zero blocks (trend p = 0.03; models adjusted for age, baseline fracture, spine or hip BMD). Stratification by baseline fracture status and controlling for other possible confounders or past year falls did not change the results. Conclusions Whereas hyperkyphosis may often result from vertebral fractures, our study findings suggest that hyperkyphotic posture itself may be an important risk factor for future fractures, independent of low BMD or fracture history.

    Osteoporosis impairs the bone-healing process as well as bone fracture fixation. The intervention of osteoporosis is considered to be one part of bone fracture treatment. Thus, orthopedic fixators impregnated with antiosteoporosis regimens will improve fracture fixation in osteoporotic bone. In this study, the strontium (Sr) and calcium phosphate ceramic (CPC) were mixed first and then mixed with poly(ε-caprolactone) (PCL) to fabricate a bioactive and bioabsorbable bone fixators. The prepared Sr-CPC/PCL screws were implanted into the distal femur of ovariectomized rabbits. The results showed that Sr-CPC/PCL composite had the appropriate mechanical properties, good biocompatibility, and radio-opacity. The Sr addition created a porous structure and accelerated the degradation of bone screws, but the degradation products did not acidify the surrounding environment. For osteoporotic animals, favorable osteointegration around the Sr-CPC/PCL screws was found, and the total porosity of trabecular bone was decreased under the inspections of micro-computerized tomography. Compared with PCL or CPC/PCL screw, animals which received Sr-CPC/PCL were found to have better results in terms of trabecular number, thickness, and separation. This study reveals that the Sr-impregnated bone fixator improves osseointegration in osteoporotic animals. Sr-CPC/PCL composite is a good candidate material for osteofixation in osteoporotic patients. PMID:25847487

    Introduction: This study aimed to determine the dislocation and reoperation rate, functional outcomes, and the survival rate of the unique subset of very old but lucid and independent patients with hip fractures following a total hip arthroplasty (THA) and geriatric team-coordinated perioperative care. Method: Between 2000 and 2006, previously independent ambulatory patients ≥80 years old presenting with an intracapsular hip fracture were given THAs under the care of an integrated orthopedic surgery–geriatric service. Their fracture-related complications, ambulation, mental status, and survival were followed for 5 to 11 years postinjury. Results: Five years postinjury, 57 (61.3%) patients of the original study group were living. In all, 3 (3.2%) patients had postoperative hip dislocations (and 2 patients had dislocation twice) and 2 reoperations were needed within the first postoperative month. There were no hip dislocations or reoperations after the first year. Radiographs obtained on 88% of the surviving patients at 5 years postoperatively showed that all remained unchanged from their immediate postoperative images. Nearly half of the patients were still able to ambulate as they did preoperatively and their mixed-model equation was statistically unchanged. Conclusion: This study of patients >80 years old with previously good functional status demonstrates that with appropriate surgical (best prosthesis, good operating technique, and regional anesthesia) and geriatric (pre- and postoperative assessments, close follow-up, medication adjustments, and fall-prevention instruction) care, they have few hip dislocations and reoperations, survive postfracture at least as long as their noninjured contemporaries, and continue to function and ambulate as they did prior to their injury.

    Aim: A previous study shows that bone morphogenetic protein 7 (BMP7) gene polymorphisms are associated with bone mineral density (BMD) in 920 European Americans. To determine the association of BMP7 polymorphisms and BMD and osteoporotic fracture susceptibility, we performed a case-control association study in postmenopausal Chinese women with or without osteoporotic fracture. Methods: A total of 3815 unrelated postmenopausal Chinese women (1238 with osteoporotic fracture and 2577 healthy controls) were recruited. BMDs of the lumbar spine 1–4 (L1–4) and proximal femur (including total hip and femoral neck) were measured using dual-energy X-ray absorptiometry. Eight tagging single nucleotide polymorphisms (SNPs) in BMP7 gene, including rs11086598, rs4811822, rs12481628, rs6025447, rs230205, rs17404303, rs162316 and rs6127980, were genotyped. Results: Among the 8 SNPs, rs6025447 and rs230205 were associated with total hip BMD (P=0.013 and 0.045, respectively). However, the associations became statistically insignificant after adjusting for age, height and weight. The TGTG haplotype of BMP7 gene was associated with total hip BMD (P=0.032), even after adjusting for age, height and weight (P=0.048); but the association was insignificant after performing the Bonferroni multiple-significance-test correction. Moreover, the 8 SNPs and 9 haplotypes of BMP7 gene were not associated with L1–4 or femoral neck BMD or osteoporotic fracture. Conclusion: This large-sample case-control association study suggests that the common genetic polymorphisms of BMP7 gene are not major contributors to variations in BMD or osteoporotic fracture in postmenopausal Chinese women.

    Background: Osteoporosis is characterized by low bone mass, bone fragility and increased susceptibility to fracture. Fracture healing in osteoporosis is delayed and rates of implant failure are high with few biological treatment options available. This study aimed to determine whether a single dose of bone morphogenetic protein-7 (BMP-7) in a collagen/carboxy-methyl cellulose (CMC) composite enhanced fracture healing in an osteoporotic rat model. Materials and Methods: An open femoral midshaft osteotomy was performed in female rats 3 months post-ovarectomy. Rats were randomized to receive either BMP-7 composite (n = 30) or composite alone (n = 30) at the fracture site during surgery. Thereafter calluses were collected on days 12, 20 and 31. Callus cross-sectional area, bone mineral density, biomechanical stiffness and maximum torque, radiographic bony union and histological callus maturity were evaluated at each time point. Results: There were statistically significant increases in bone mineral density and callus cross-section area at all time points in the BMP-7 group as compared to controls and biomechanical readings showed stronger bones at day 31 in the BMP-7 group. Histological and radiographic evaluation indicated significant acceleration of bony union in the BMP-7 group as compared to controls. Conclusion: This study demonstrated that BMP-7 accelerates fracture healing in an oestrogen-deficient environment in a rat femoral fracture healing model to scientific relevance level I. The use of BMP-7 composite could offer orthopedic surgeons an advantage over oestrogen therapy, enhancing osteoporotic fracture healing with a single, locally applied dose at the time of surgery, potentially overcoming delays in healing caused by the osteoporotic state.

    There are an increasing number of fragility fractures, which present a surgical challenge given the reduced bone quality of underlying osteoporosis. Particularly in aged patients, there is a need for early weight bearing and mobilization to avoid further complications such as loss of function or autonomy. As an attempt to improve fracture stability and ultimate healing, the use of biomaterials for augmentation of osseous voids and fracture fixation is a promising treatment option. Augmentation techniques can be applied in various locations, and fractures of the metaphyseal regions such as proximal humerus, femur, tibia and the distal radius remain the most common areas for its use. The current review, based on the available mechanical and biological data, provides an overview of the relevant treatment options and different composites used for augmentation of osteoporotic fractures.

    Hip fracture management by the geriatrician demands a close cooperation with orthopedic surgeons and a interdisciplinary approach with the implementation of protocole-driven care to standardize the care of most patients. From admission to discharge this orthogeriatric management is based on the comprehensive geriatric assessment to reduce the delays in surgery, the occurence of delirium or the most postoperative complications. This collaborative model of care seems to have the potential to improve function, admissions to nursing homes and mortality outcomes compared with usual care of geriatric patient with hip fracture.

    Hip fractures are associated with significant mortality and morbidity for the patients, more dependent residual status, and increased socio-economic cost. Many hip-fracture patients experience severe functional impairment, and most never recover their pre-fracture level of function. Current research has sought to identify the most effective treatments to reduce the incidence of hip fractures, improve survival and quality of life, and minimize complications and disability. The treatment of these fractures in the elderly aims to return these people to their pre-fracture mobility and functional level. This article reviews the surgical treatment options for extracapsular hip fractures and discusses their associated advantages, disadvantages, and complications. Two types of implants are currently available: the dynamic hip screw (DHS), and the intramedullary hip nail with one or two sliding screws. In this review, no clear advantage of one implant over another for the treatment of extracapsular hip fractures was evident. Both the DHS and hip nails can be used successfully for the treatment of stable hip fractures; for unstable fractures and low subtrochanteric fractures, hip nails are preferred. Although hip nails are associated with limited exposure, lower blood loss and transfusion requirements, and shorter operative time, complications are more common with hip nails. Long-term survival and function are similar in the two approaches. Hip nails with two sliding screws do not seem to make the difference in clinical practice that is reported in biomechanical studies.

    Historically, treatment decisions for osteoporosis were based on bone mineral density. However, many fractures occur in patients with T-scores outside the osteoporotic range, emphasizing the importance of multi-factorial risk assessments. The World Health Organization Fracture Risk Assessment Tool (FRAX) predicts 10-year risk of osteoporotic fracture. We hypothesized that physicians' clinical estimates of osteoporotic fracture risk would differ significantly from that calculated by FRAX. Thus, treatment decisions would differ depending whether or not physicians used FRAX. A survey consisting of five clinical scenarios was administered to 76 endocrinologists, family physicians, internists, and internal medicine residents. They were asked to estimate the osteoporotic fracture risk and decide whether they would offer preventative treatment. Their estimates were compared to the risk predicted by FRAX and national treatment threshold guidelines. The primary outcome was the difference between the participant's estimate and the FRAX-based estimate of the 10-year risk of osteoporotic fracture for each scenario. In each scenario, physicians statistically significantly over-estimated fracture risk compared to that predicted by FRAX. Estimates for hip fracture risk were 2-4 times higher than FRAX estimates. The major osteoporotic fracture risk at which participants would offer treatment varied with physician group, with endocrinologists, family physicians, and residents requiring a 10-20 % 10-year risk, while internal medicine physician thresholds ranged from 2 to 20 %. Physicians greatly over-estimated the risk of hip fracture based on clinical information. FRAX is necessary to accurately quantify risk, but because physicians varied in the level of risk required before they would offer treatment, uniform approaches to risk estimation may still not result in uniform clinical treatment decisions.

    Fixation techniques of periprosthetic fractures are far from ideal although the number of this entity is rising. The presence of an intramedullary implant generates its own fracture characteristics since stiffness is altered along the bone shaft and certain implant combinations affect load resistance of the bone. Influencing factors are cement fixation of the implant, intramedullary locking and extramedullary or intramedullary localization of the implant and the cortical thickness of the surrounding bone. Cerclage wires are ideally suited to fix radially displaced fragments around an intramedullary implant but they are susceptible to axial and torsional load. Screws should be added if these forces have to be neutralized. Stability of the screw fixation itself can be enhanced by embracement configuration around the intramedullary implant. Poor bone stock quality, often being present in metaphyseal areas limits screw fixation. Cement augmentation is an attractive option in this field to enhance screw purchase. PMID:27338227

    Vertebral fractures are the most common osteoporotic fractures. To perform percutaneous vertebral body cement augmentation, it is essential to accurately identify the affected vertebrae. The study evaluated the role of radionuclide bone imaging in identifying fresh osteoporotic vertebral compression fractures. A prospective study of 39 patients with acute osteoporotic vertebral compression fractures was carried out. All patients underwent magnetic resonance imaging (MRI) and radionuclide bone imaging to determine if the fractures were fresh, followed by percutaneous kyphoplasty for the fresh fractures. The positive rate on radionuclide bone imaging was 92.1% (82/89), and the positive rate on MRI was 93.3% (83/89), with no statistically significant difference (P > 0.05). Eighty-one vertebrae had the same positive identification by both radionuclide bone imaging and MRI, and 5 of the same vertebrae were diagnosed negative by both techniques. One patient with positive radionuclide bone imaging was negative according to MRI, and 2 patients were entirely positive by MRI but negative by radionuclide bone imaging. A kappa test showed good consistency between the 2 methods for detecting the affected vertebrae (Kappa = 0.751, P < 0.01). Radionuclide bone imaging is as sensitive as MRI in the diagnosis of fresh osteoporotic vertebral compression fracture, making it an effective method for detecting affected vertebrae for percutaneous vertebroplasty.

    The aim of this work is the application of a mechanical predictive model to a sample of people over 60 years of age, in order to analyze the fracture probability related to age and sex. A total of 223 elderly people (63 men, aged 63-88, 72.32±6.10; 157 women, aged 61-89, 73.28±5.73) participated in the study. A dual-energy X-ray absorptiometry scanner was used to measure the bone mineral content and bone mineral density at total hip and femoral neck. The application of the predictive model also required a finite element simulation of the proximal femur, obtaining the mechanical damage and fracture probability maps corresponding to each sex and age groups analyzed. Statistical analysis shows higher values of bone mineral density, and consequently of Young's modulus, for men than for women. In general, a decrease of BMD is observed since 65 years old. The maximum mechanical damage value is always located at the femoral neck. The results indicate that mechanical damage tends to increase with age. Coherently with mechanical damage, the maximum fracture probability value is always located at the femoral neck and tends to increase with age. The simulation model to determine the probability of fracture is more complete than the simple measurement of bone mineral density, because provides additional information about mechanical properties of bone, and allows for a prospective detection of fracture risk. The model may be used for risk evaluation in specific patients, if anatomical and dual-energy X-ray absorptiometry measurements are available, helping us to decide about preventive pharmacological treatment for hip fracture.

    Biomechanical tests are widely used in animal studies on osteoporotic fracture healing. However, the biomechanical recovery process is still unknown, leading to difficulty in choosing time points for biomechanical tests and in correctly assessing osteoporotic fracture healing. To determine the biomechanical recovery process during osteoporotic fracture healing, studies on osteoporotic femur fracture healing with biomechanical tests in ovariectomized rat (OVX) models were collected from PUBMED, EMBASE, and Chinese databases. Quadratic curves of fracture healing time and maximum load were fitted with data from the analyzed studies. In the fitted curve for normal fractures, the predicted maximum load was 145.56 N, and the fracture healing time was 88.0 d. In the fitted curve for osteoporotic fractures, the predicted maximum load was 122.30 N, and the fracture healing time was 95.2 d. The maximum load of fractured femurs in OVX rats was also lower than that in sham rats at day 84 post-fracture (D84 PF). The fracture healing time was prolonged and maximum load at D84 PF decreased in OVX rats with closed fractures. The maximum load of Wister rats was higher than that of Sprague-Dawley (SD) rats, but the fracture healing time of SD and Wister rats was similar. Osteoporotic fracture healing was delayed in rats that were < = 12 weeks old when ovariectomized, and at D84 PF, the maximum load of rats < = 12 weeks old at ovariectomy was lower than that of rats >12 weeks old at ovariectomy. There was no significant difference in maximum load at D84 PF between rats with an osteoporosis modeling time <12 weeks and > = 12 weeks. In conclusion, fracture healing was delayed and biomechanical property decreased by osteoporosis. Time points around D95.2 PF should be considered for biomechanical tests of osteoporotic femur fracture healing in OVX rat models. Osteoporotic fracture healing in OVX rats was affected by the fracture type but not by the strain of the rat. PMID:27055104

    We examined if height loss in older women predicts risk of hip fractures, other non-spine fractures, and mortality, and whether this risk is independent of both vertebral fractures (VFx) and bone mineral density (BMD) by dual-energy x-ray absorptiometry. Among 3,124 women age 65 and older in the Study of Osteoporotic Fractures, we assessed the association with measured height change between Year 0 (1986–1988) and Year 15 (2002–2004) and subsequent risk of radiologically confirmed hip fractures, other non-spine fractures, and mortality assessed via death certificates. Follow-up occurred every 4 months for fractures and vital status (>95% contacts complete). Cox proportional hazards models assessed risk of hip fracture, non-spine fracture, and mortality over a mean of 5 years after height change was assessed (i.e, after final height measurement). After adjustment for VFx, BMD and other potential covariates, height loss >5 cm was associated with a marked increased risk of hip fracture (HR 1.50, 95% CI 1.06, 2.12), non-spine fracture (HR 1.48; 95% CI 1.20, 1.83), and mortality (1.45; 95% CI 1.21, 1.73). Although primary analyses were a subset of 3,124 survivors healthy enough to return for a Year 15 height measurement, a sensitivity analysis in the entire cohort (n=9,677) using initial height in earlier adulthood (self-reported height at age 25 [−40 years] to measured height age >65 years [Year 0]) demonstrated consistent results. Height loss >5 cm (2”) in older women was associated with a nearly 50% increased risk of hip fracture, non-spine fracture, and mortality—independent of incident VFx and BMD. PMID:22072593

    Purpose With ethical requirements to the enrollment of lower risk subjects, osteoporosis trials are underpowered to detect reduction in hip fractures. Different skeletal sites have different levels of fracture risk and response to treatment. We sought to identify fracture sites which cluster with hip fracture at higher than expected frequency; if these sites respond to treatment similarly, then a composite fracture endpoint could provide a better estimate of hip fracture reduction. Methods Cohort study using Veterans Affairs and Medicare administrative data. Male Veterans (n=5,036,536) aged 50-99 years receiving VA primary care between1999-2009 were included. Fractures were ascertained using ICD9 and CPT codes and classified by skeletal site. Pearson correlation coefficients, logistic regression and kappa statistics, were used to describe the correlation between each fracture type and hip fracture within individuals, without regards to the timing of the events. Results 595,579 (11.8%) men suffered 1 or more fractures and 179,597 (3.6%) suffered 2 or more fractures during the time under study. Of those with one or more fractures, rib was the most common site (29%), followed by spine (22%), hip (21%) and femur (20%). The fracture types most highly correlated with hip fracture were pelvic/acetabular (Pearson correlation coefficient 0.25, p<0.0001), femur (0.15, p<0.0001), and shoulder (0.11, p<0.0001). Conclusions Pelvic, acetabular, femur, and shoulder fractures cluster with hip fractures within individuals at greater than expected frequency. If we observe similar treatment risk reductions within that cluster, subsequent trials could consider use of a composite endpoint to better estimate hip fracture risk. PMID:26151123

    Objectives. This study collected and evaluated data on the costs of outpatient medical care and family burden associated with osteoporosis-related fracture rehabilitation following hospital discharge in China. Materials and Methods. Data were collected using a patient questionnaire from osteoporosis-related fracture patients (N = 123) who aged 50 years and older who were discharged between January 2011 and January 2013 from 3 large hospitals in China. The survey captured posthospital discharge direct medical costs, indirect medical costs, lost work time for caregivers, and patient ambulatory status. Results. Hip fracture was the most frequent fracture site (62.6%), followed by vertebral fracture (34.2%). The mean direct medical care costs per patient totaled 3,910¥, while mean indirect medical costs totaled 743¥. Lost work time for unpaid family caregivers was 16.4 days, resulting in an average lost income of 3,233¥. The average posthospital direct medical cost, indirect medical cost, and caregiver lost income associated with a fracture patient totaled 7,886¥. Patients' ambulatory status was negatively impacted following fracture. Conclusions. Significant time and cost of care are placed on patients and caregivers during rehabilitation after discharge for osteoporotic fracture. It is important to evaluate the role and responsibility for creating the growing and inequitable burden placed on patients and caregivers following osteoporotic fracture. PMID:26221563

    Management of geriatric hip fractures in a protocol-driven center can improve outcomes and reduce costs. Nonetheless, this approach has not spread as broadly as the effectiveness data would imply. One possible explanation is that operating such a center is not perceived as financially worthwhile. To assess the economic viability of dedicated hip fracture centers, the authors built a financial model to estimate profit as a function of costs, reimbursement, and patient volume in 3 settings: an average US hip fracture program, a highly efficient center, and an academic hospital without a specific hip fracture program. Results were tested with sensitivity analysis. A local market analysis was conducted to assess the feasibility of supporting profitable hip fracture centers. The results demonstrate that hip fracture treatment only becomes profitable when the annual caseload exceeds approximately 72, assuming costs characteristic of a typical US hip fracture program. The threshold of profitability is 49 cases per year for high-efficiency hip fracture centers and 151 for the urban academic hospital under review. The largest determinant of profit is reimbursement, followed by costs and volume. In the authors’ home market, 168 hospitals offer hip fracture care, yet 85% fall below the 72-case threshold. Hip fracture centers can be highly profitable through low costs and, especially, high revenues. However, most hospitals likely lose money by offering hip fracture care due to inadequate volume. Thus, both large and small facilities would benefit financially from the consolidation of hip fracture care at dedicated hip fracture centers. Typical US cities have adequate volume to support several such centers. PMID:24579222

    The trabecular bone mineral content (BMC) of the spine was measured by computed tomography in 185 women aged 47-84 years with vertebral fracture (n = 74), hip fracture (n = 83), and both vertebral and hip fracture (n = 28). Eighty-seven percent of vertebral-fracture patients, 38% of hip-fracture patients, and 82% of vertebral- and hip-fracture patients had spinal BMC values below the fifth percentile for healthy premenopausal women and values 64%, 9%, and 68% below the fifth percentile for age-matched control subjects. No significant loss of spinal trabecular bone was seen in patients with hip fracture. If it is assumed that the rate of trabecular bone loss is the same in the spine and femoral neck, then hip fracture (unlike osteoporotic vertebral fracture) is not associated with disproportionate loss of trabecular bone. Hip fracture occurs secondary to weakening of bone and increased incidence of falls. Bone weakening may be due to disproportionate loss of trabecular or cortical bone, proportionate loss of both, or other as yet undetermined qualitative changes in bone.

Overview of Literature The diagnosis of new fractrure in osteoporotic vertebral fractures requires simple X-ray and supplementary studies. Methods We analyzed 87 vertebrae in 44 patients, who diagnosed with osteoporotic vertebral fractures using bone scan and MRI within 2 months interval between August 2001 and July 2008. We compared hot uptakes in bone scan with MRI findings such as new fractures, old fractures and degenerative lesions. Results Hot uptakes in bone scan was matched to 48 new fractures, 26 old fractures and 13 degenerative lesions in MRI findings. It was 55% of concordance between hot uptakes in bone scan and new fractures in MRI. The rate of new vertebral fractures confirmed by MRI according to 1 level hot uptakes in bone scan was 96%, 2 levels was 50% and 3 more levels was 36%. Conclusions The diagnosis of new fracture in osteoporotic vertebral fractures requires simple X-ray and supplementary studies such as bone scan and MRI. We recommend more careful interpretation in multiple osteoporotic vertebral fracture patients about hot uptake lesions of bone scan. PMID:21165311

    Background Fracture-risk assessment tool (FRAX) using just clinical risk factors of osteoporosis has been developed to estimate individual risk of osteoporotic fractures. We developed prediction model of fracture risk using bone mineral density (BMD) as well as clinical risk factors in Korean, and assessed the validity of the final model. Methods To develop and validate an osteoporotic FRAX, a total of 768 Korean men and women aged 50 to 90 years were followed for 7 years in a community-based cohort study. BMD as well as clinical risk factors for osteoporotic fracture including age, sex, body mass index, history of fragility fracture, family history of fracture, smoking status, alcohol intake, use of oral glucocorticoid, rheumatoid arthritis, and other causes of secondary osteoporosis were assessed biannually. Results During the follow-up period, 86 osteoporotic fractures identified (36 in men and 50 in women). The developed prediction models showed high discriminatory power and had goodness of fit. Conclusions The developed a Korean specific prediction model for osteoporotic fractures can be easily used as a screening tool to identify individual with high risk of osteoporotic fracture. Further studies for validation are required to confirm the clinical feasibility in general Korean population. PMID:26981519

    Purpose The objective of this study was to provide new estimates on the per-admission inpatient hospital cost and per-admission length of stay (LOS) for osteoporosis-related fractures in mainland China. Materials and methods Data for inpatient hospitalization associated with at least one osteoporosis-related fracture were obtained from the nationwide China Health Insurance Research Association and were analyzed post hoc. Patients’ data were included if the patients were ≥50 years old and diagnosed with osteoporosis and pathologic fracture, or osteoporosis therapy and fragility fracture by an International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) code designation, between 2008 and 2010. Results The analysis included 830 patients (female: 77.3%; mean age: 73.4±9.8 years). The medians of the per-admission LOS and inpatient costs were 19 days and ¥18,587, respectively. Longer LOS and higher costs per admission were associated with older patients (≥70 years) compared to younger patients (<70 years). Hip fracture had the longest median LOS (22 days) and highest median cost (¥32,594) among all fracture sites. The per-hospitalization episode and per-day costs of osteoporotic fracture increased rapidly (60% and 89%, respectively) between 2008 and 2010. Conclusion The analysis showed that hospitalization cost increases were associated with increasing per-day hospitalization costs. The proportion of the costs reimbursed by health insurances increased, while the mean absolute patient copayment amounts decreased. The incidence and prevalence of osteoporosis and osteoporosis-related fractures may rise rapidly due to the projected growth of the aged population in mainland China. Therefore, the combination of greater anticipated total fractures and rising hospital costs may lead to a tremendously increased economic burden in the future. PMID:25926747

    Summary Osteoporosis is a well acknowledged complication of spinal cord injury. We report that motor complete spinal cord injury and post-injury alcohol consumption are risk factors for hospitalization for fracture treatment. The clinical assessment did not include osteoporosis diagnosis and treatment considerations, indicating a need for improved clinical protocols. Introduction Treatment of osteoporotic long bone fractures often results in lengthy hospitalizations for individuals with spinal cord injury. Clinical features and factors that contribute to hospitalization risk have not previously been described. Methods Three hundred and fifteen veterans ≥ 1 year after spinal cord injury completed a health questionnaire and underwent clinical exam at study entry. Multivariate Cox regression accounting for repeated events was used to assess longitudinal predictors of fracture-related hospitalizations in Veterans Affairs Medical Centers 1996–2003. Results One thousand four hundred and eighty-seven hospital admissions occurred among 315 participants, and 39 hospitalizations (2.6%) were for fracture treatment. Median length of stay was 35 days. Fracture-related complications occurred in 53%. Independent risk factors for admission were motor complete versus motor incomplete spinal cord injury (hazard ratio = 3.73, 95% CI = 1.46–10.50). There was a significant linear trend in risk with greater alcohol consumption after injury. Record review indicated that evaluation for osteoporosis was not obtained during these admissions. Conclusions Assessed prospectively, hospitalization in Veterans Affairs Medical Centers for low-impact fractures is more common in motor complete spinal cord injury and is associated with greater alcohol use after injury. Osteoporosis diagnosis and treatment considerations were not part of a clinical assessment, indicating the need for improved protocols that might prevent low-impact fractures and related admissions.

    Hip fractures are among the most common fractures in elderly people. The annual number of femoral fractures is even expected to increase because of an aging society. Due to the high number of comorbidities, there are special challenges in treating geriatric hip fracture patients, which require a multidisciplinary management. This includes surgical treatment allowing full weight bearing in the immediate postoperative period, osteoporosis treatment and falls prevention as well as an early ortho-geriatric rehabilitation program.

    Osteoporotic fragility fractures of the femoral neck are the most common type of fractures in the elderly and are associated with a high mortality. Most frequently these fractures are due to falls but spontaneous onset has also been described. In these patients the insufficient quantity and quality of the osteoporotic bone finally leads to the development of a fragility or insufficiency fracture. In some cases of nondisplaced insufficiency fractures the diagnosis cannot be established by conventional radiographs alone and magnetic resonance imaging (MRI), single proton emission computed tomography (SPECT) or SPECT/CT are considered as diagnostic adjuncts. We report the case of an 83-year-old patient who had complained of ongoing weight-bearing pelvic pain for over 6 months. There was no history of trauma. The clinical conventional radiographs as well as CT could not elucidate the cause of the problems. To differentiate between lumbal and hip pain a SPECT/CT was performed and the diagnosis of a medial femoral neck insufficiency fracture was established. In the delayed phase a band-like increased tracer uptake within the medial femoral neck was observed. The SPECT/CT procedure is a promising diagnostic alternative for geriatric patients and can be particularly recommended in cases of persistent unclear pelvic or lumbar spine pain in the elderly.

    Objective To study the relationship of plasma homocysteine (Hcy), bone turnover biomarkers (BTB), and bone mineral density (BMD) with osteoporotic fracture (OPF) in elderly people. Methods Eighty-two patients (aged 65 years or older) admitted to our orthopedics department between October 2014 and May 2015 were randomly divided into three groups: 1) OPF group: 39 cases with the mean age 81.82±5.49 years, which included 24 females and 15 males; 2) high-energy fracture (HEF) group: 22 cases with the mean age 78.88±5.75 years, which included 16 females and six males; 3) non-bone-fracture group: 21 cases with mean age 79.75±5.47 years without bone fracture, which included 14 females and seven males. Plasma Hcy, BTB, and BMD were measured. Analysis of variance and multiple regression analysis were used in the statistical analysis. Results There was no significant difference in either age or sex among the three groups. There were significant differences in plasma Hcy and hip BMD between the OPF and HEF groups; there was also significant difference in plasma Hcy, 25-(OH) Vit D, and hip BMD between the OPF and non-fracture groups. There was no difference in lumbar spine BMD between the OPF group and the other two groups. There was no significant difference in plasma Hcy, 25-(OH) Vit D, hip or lumbar spine BMD between the HEF and non-fracture group. There was no significant difference in procollagen type I N-propeptide of type I collagen, serum C-terminal cross-linking telopeptide of type I collagen, and parathyroid hormone among the three groups. Plasma Hcy was linearly correlated with age and serum C-terminal cross-linking telopeptide of type I collagen, but not correlated with either hip or lumbar spine BMD or any other BTBs. Conclusion In this study, we found that the plasma Hcy level in elderly patients with OPF is higher than that of nonosteoporotic patients. It is not correlated with BMD, but positively correlated with bone resorption markers. An increased Hcy

    This manuscript will evaluate the published evidence on efficacy of organized hip fracture programs to determine if they improve patient outcomes. A detailed literature search was conducted to find manuscripts published in the past 20 years about organized hip fracture care programs. Seventeen programs with published results were identified from this detailed search and these were evaluated and synthesized in the following manuscript. Organized hip fracture programs offer significant benefits to patients, care providers and health systems. The more complex program designs have a more profound effect on improvement in outcomes for hip fracture patients. Most programs have reported reduced length of stay, reduced in-hospital mortality rates, and reduced complications. Some programs have reported reduced costs and reduced readmission rates after implementing an organized hip fracture program. PMID:26768285

    Purpose This study was designed to investigate the effect of bisphosphonate administration starting time on bone healing and to identify the best administration time following surgical treatment of osteoporotic intertrochanteric fractures. Materials and Methods Two hundreds and eighty four patients (284 hips; 52 males, 232 females) who underwent surgery following osteoporotic intertrochanteric fracture from December 2002 to December 2012 were retrospectively analyzed. The average follow-up period was 68.4 months. The patients were divided into three groups according to the time of bisphosphonate administration after operation: 1 week (group A; n=102), 1 month (group B; n=89), and 3 months (group C; n=93). Koval scores and change of Koval scores 1 year after operation were used for clinical evaluation. For radiologic evaluation, the time of callus appearance across the fracture line on sagittal and coronal radiographs and the time to absence of pain during hip motion was judged as the time of bone union. Results Koval scores one year after surgery for groups A, B, and C were 2.44, 2.36, and 2.43 (P=0.895), respectively. The mean time of union was 12.4, 11.9, and 12.3 weeks after operation in the three groups (P=0.883), respectively. There were zero cases of nonunion. There were 3, 5, and 7 cases of fixative displacement in the three groups, respectively, but the distribution showed no significant difference (P>0.472). Conclusion The initiating time of bisphosphonate administration following surgery does not affect the clinical outcomes in patients with osteoporotic intertrochanteric fracture. PMID:27536634

    In Finland approximately 7,000 hip fractures occurred annually during 1996-2008. Risk of hip fracture can be diminished through efforts to prevent falls and osteoporosis. A hip fracture is treated operatively, with the aim of early mobilisation and full weight bearing. Postoperative care and rehabilitation requires multidisciplinary and multifaceted management, focusing on improvement of the patient's physical condition, appropriate pain management, the prevention of delirium and other possible complications. Rehabilitation should be centralised in specialised rehabilitation centres for the elderly. Secondary prevention of future fractures should include management of osteoporosis and fall prevention.

    Hip fractures represent the most severe complication of osteoporosis from the perspectives of the patient, carer, health care system and society. Given the strong association with age, numbers are set to rise significantly in the next few decades despite evidence that the age adjusted rates in some countries are either plateauing or falling. Given the almost invariable need for inpatient admission, hospital administrative data for hip fractures remain a robust measure of number of hip fractures in the community and can be extrapolated to determine the total expected number of clinical fragility fractures from the same population. Both process and outcome standards have now been developed to benchmark clinical quality in the care of patients with hip fractures and fragility fractures at other sites. PMID:24836330

    Kyphoplasty (KP) and vertebroplasty (VP) have been successfully employed for many years for the treatment of osteoporotic vertebral fractures. The purpose of this review is to resolve the controversial issues raised by the two randomized trials that claimed no difference between VP and SHAM procedure. In particular we compare nonsurgical management (NSM) and KP and VP, in terms of clinical parameters (pain, disability, quality of life, and new fractures), cost-effectiveness, radiological variables (kyphosis correction and vertebral height restoration), and VP versus KP for cement extravasation and complications profile. Cement types and optimal filling are analyzed and technological innovations are presented. Finally unipedicular/bipedicular techniques are compared. Conclusion. VP and KP are superior to NSM in clinical and radiological parameters and probably more cost-effective. KP is superior to VP in sagittal balance improvement and cement leaking. Complications are rare but serious adverse events have been described, so caution should be exerted. Unilateral procedures should be pursued whenever feasible. Upcoming randomized trials (CEEP, OSTEO-6, STIC-2, and VERTOS IV) will provide the missing link. PMID:24724106

  11. Use of the talon hip compression screw in intertrochanteric fractures of the hip.

    Bramlet, Dale G

    2004-08-01

    A retrospective analysis of a compression hip screw with four reversibly deployable talons was done. Fifty-four patients had sufficient radiographs to be included in this analysis. One-year mortality was 17% and increased to 41% by 2 years. No lag screws cut out, and postoperative slide was reduced compared with that in many published series. Three patients had revision of a failed alternate-type hip pin with the Talon hip compression screw. Previous studies showed the talons provide the definitive difference in allowing enhanced compression at the time of surgery, preventing cut-out by enhanced rotational stability, and allowing immediate postoperative weightbearing without excessive limb shortening. The failure mode of the Talon compression hip screw seems to be side-plate loosening rather than varus deformity and lag screw cut-out. The Talon compression hip screw especially is effective with weak, osteoporotic bone and in unstable, three-part and four-part fractures. A previous study showed that Talon deployment notably improved interfragment compression and torsional strength, and that engagement or penetration into or through the cortical bone at the base of the femoral head-neck junction in the inferior lag screw position was the critical technical step to maximize the talon lag screw purchase.

    The aim of this work is to study the prevalence of osteoporotic vertebral fractures in Spanish women over 45 years of age, based on the selection of a nationwide sample. An observational, cross-sectional, multicenter study was conducted during 2006, in all of Spain's regions. The sample analyzed was of 5000 individuals, representative of the female population over age 45 in Spain. A questionnaire was used to determine which factors are most often associated with vertebral fractures. We also assessed whether the Prevalent Vertebral Fracture Index, proposed by Vogt, is useful in indicating a possible osteoporotic vertebral fracture. Five hundred orthopedic surgeons, from various Spanish regions, were trained in different aspects of the study: inclusion and exclusion criteria, management of the risk factor questionnaire, and implementation of the Vogt questionnaire. The number of fracture cases was 1549 (31.79%). 528 Women (34.08%) had a single vertebral fracture, and 1021 (65.92%) had multiple vertebral fractures. The following factors were statistically significantly associated with vertebral fracture: age, late menarche, early menopause, diabetes mellitus, hyperparathyroidism, rheumatoid arthritis, height loss, daily physical activity, corticosteroid therapy, personal history of osteoporotic fracture and previous diagnosis of osteoporosis. The differences in Vogt score according to age and fracture status were statistically significant. The conclusion of the study is that vertebral osteoporotic fracture in the female Spanish population is frequent. The high prevalence in the Spanish population older than 60 years is probably related to malnutrition in the period from 1936 to 1952. PMID:25577153

    We report on a case of a 65-year-old (CD) woman who sustained an atraumatic neck fracture. A combination of Parkinson's disease with motor fluctuations, chronic cervical dystonia and osteoporosis provided the basis for this interesting diagnosis. Mrs CD had progressed to complex phase idiopathic Parkinson's disease within 13 years of diagnosis. During this time she remained independent, only using a wheelchair when her motor fluctuations were bad. In 2011, she developed a sudden onset of neck spasm and occipital neuralgia, initially attributed to severe spasmodic cervical dystonia. Despite a titration regime of analgesics and weaning off of her Parkinson's disease medications, the pain persisted. An X-ray of her cervical spine showed degenerative discopathies from C4 to C7. Mrs CD underwent a trial of Botox injections to no avail and she was admitted acutely under the spinal team after an MRI of her spine showed abnormal oedema of the odontoid peg. Subsequent CT diagnosed a type II fracture of the odontoid peg on the background of severe osteoporotic bone (spinal T score -3.4 on subsequent DEXA scan) and she underwent a successful occipital cervical fusion of C1-C6. What makes this case interesting is the fact that this lady's profound powerful neck movements on a background of osteoporosis led to fracture of her neck. Post-operatively, she admitted to non-adherence to her bisphosphonates, prioritising levodopa in the morning with food rather than taking her alendronate on an empty stomach. She is now pain free and receives annual zolendronate infusions. PMID:23672934

    Introduction: Subchondral insufficiency fracture (SIF) of femoral head is not very common cause of hip pain. This usually occurs in elderly osteoporotic patients or fatigue fracture in young military recruits. Case Report: We report a case of hip pain in an osteoporotic male which was diagnosed on MRI after the condition was missed by two physicians initially. Patient responded well to conservative treatment and was asymptomatic at one year follow up. Conclusion: Purpose of this case is to highlight clinical and radiological features of this entity and to discuss the prognosis and treatment. This case should increase awareness of this rare condition amongst treating physicians. This may facilitate early diagnosis and successful outcome with conservative treatment in selected sub-group of patients having SIF of femoral head.

    Brace is one of the most commonly used interventions to manage osteoporotic vertebral fracture. However, its authentic effectiveness remains unclear. The aim of this study was to investigate the efficacy of brace in patients with osteoporotic vertebral fractures. We conducted a literature review and meta-analysis following the guideline and handbook of the Cochrane collaboration. Ten published articles were included in this study and data from 4 randomized controlled trials were analyzed. Low quality evidence proved using Spinomed brace could bring large and significant beneficial effect to patients with sub-acute osteoporotic vertebral fractures. Very low quality evidence proved no significant difference between Spinomed orthosis, rigid brace and soft brace when they were used in patients with acute fractures. Therefore, it might be applicable to recommend middle term use of Spinomed orthosis to patients with subacute fracture. In addition, this study emphasized the need for high quality randomized controlled trials. PMID:27550495

    Context Nonvertebral fractures (NVFs) are the most costly and disabling type of osteoporotic fractures. Bisphosphonate therapy effectively reduces the risk for NVFs; however, fracture protection depends critically on adherence and persistence. Approved bisphosphonate regimens with extended dosing intervals increase patient convenience, help patients remain on therapy, and improve fracture protection in clinical practice. Evidence Acquisition To assess evidence for NVF reduction with extended-interval bisphosphonates, we searched PubMed for phase 3 clinical trials, meta-analyses, and reviews of approved nitrogen-containing bisphosphonate regimens with monthly or less frequent dosing (monthly oral ibandronate, monthly or intermittent oral risedronate, quarterly intravenous [IV] ibandronate, and yearly IV zoledronic acid). These references were augmented by ISI Web of Science cited reference searches, ISI Proceedings searches, and hand searches of relevant conference proceedings and review bibliographies. Evidence Synthesis Monthly oral and quarterly IV ibandronate reduce NVF risk significantly more than daily oral ibandronate and placebo, as shown by meta-analyses stratified by ibandronate dose (annual cumulative exposure). Intermittent and monthly oral risedronate have shown bone density gains similar to those seen with daily oral risedronate. Incidence rates of NVF, reported as adverse events, were also similar. Yearly IV zoledronic acid reduced NVF risk by 25% and hip fracture risk by 41% compared with placebo in its pivotal trial for postmenopausal osteoporosis. Conclusions Extended-interval bisphosphonates offer similar or superior NVF protection with less lifestyle disruption compared with daily or weekly treatment. By removing obstacles to adherence and persistence, extended-interval oral and IV bisphosphonate regimens provide valuable therapeutic options to enhance real-world effectiveness and reduce NVF incidence.

    Objective Celiac disease is associated with decreased bone density, however, the risk of fractures in celiac disease patients is unclear. We compared the prevalence of celiac disease between a group of women with hip fractures and a group of women undergoing elective joint replacement surgery and the association between celiac disease and vitamin D levels. Methods Two hundred eight community dwelling and postmenopausal women were recruited from Boston, MA (n=81) and Baltimore, MD (n=127). We measured tissue transglutaminase IgA by ELISA to diagnose celiac disease and 25-hydroxyvitamin D (25(OH)D) levels by radioimmunoassay in both women with hip fractures (n=157) and the control group (n=51), all of whom were from Boston. Subjects were excluded if they took any medications or had medical conditions that might affect bone. Results Median serum 25(OH)D levels were significantly lower (p< 0.0001) in the hip fracture cohorts compared to the elective joint replacement cohort (14.1 ng/ml vs. 21.3 ng/ml, respectively). There were no differences in the percentage of subjects with a positive tissue transglutaminase in the women with hip fractures versus the control group (1.91% vs. 1.61%, respectively). Conclusion Vitamin D levels are markedly reduced in women with hip fractures, however hip fracture patients did not show a higher percentage of positive tissue transglutaminase levels compared with controls. These data suggest that routine testing for celiac disease among hip fracture patients may not prove useful, although larger prospective studies among hip fracture subjects are needed. PMID:23732553

    The objective of this study was to compare a cohort of geriatric patients with operatively managed isolated fractures below the hip to a cohort of geriatric patients with operatively managed isolated hip fractures. All patients greater than 59 years of age admitted to our institution for surgical care of an isolated lower extremity fracture during a 3-year period were included. Patients were divided into 2 cohorts: BTH (fracture below the subtrochanteric region of the femur) and HIP (proximal femoral fracture at subtrochanteric region or proximal). We identified 141 patients included in cohort BTH and 205 patients included in cohort HIP. HIP patients were older (P < .01) and less obese (P < .01) but were otherwise very similar. An extensive comorbidity review revealed that the 2 cohorts were similar, with the exception of an increased incidence of dementia (P = .012) or glaucoma (P = .04) in HIP patients and of peripheral neuropathy (P = .014) in BTH patients. HIP patients were more likely to be under active antiosteoporotic medication management and were more likely to be receiving pharmacological anticoagulation at the time of admission. HIP patients and BTH patients were similar with regard to necessity of assistance with ambulation preinjury, but HIP patients were less likely to reside independently at home than were BTH patients (P < .001). HIP patients were also less likely to be discharged directly home from the hospital (P < .001). Geriatric patients with fractures below the hip are medically similar to geriatric patients with hip fracture. Medical comanagement protocols have been extensively published that improve care of geriatric patients with hip fracture; consideration should be given to similar protocol-driven medical comanagement programs for geriatric patients with fractures below the hip.

    Genetic, environmental, or hormonal factors may cause heterogeneity in skeletal load response. Individuals with reduced sensitivity to load should require higher strains to generate an adaptive response, consequently have weaker bones and fracture more frequently. The purpose of our study was to determine if stresses (proportional to strains) at the femoral neck under equivalent loads were higher in women with a history of fractures compared with women without fractures. We studied postmenopausal women participating in the Canadian Multicentre Osteoporosis Study who had available hip structure analysis data from dual-energy X-ray absorptiometry scans (n = 2168). Women were categorized into 2 groups based on their number of self-reported fractures. We computed stress (megapascals) at the inferomedial margin of the femoral neck in a one-legged stance mode using a 2-dimensional engineering beam analysis. We used linear regression (SAS 9.3) to determine associations between stress, geometry parameters, and number of fractures. Postmenopausal women with 1 or more fractures had higher stress (2.6%), lower narrow neck bone mineral density (4.2%), cross-sectional area (3.9%), and section modulus (9.6%) than postmenopausal women without fractures (all p < 0.05). These findings provide evidence of heterogeneity in load response and suggest an important role for modeling in the pathogenesis of osteoporotic fracture. PMID:23478079

    Osteoporotic compression fractures (VCFs) can result in progressive kyphosis and chronic pain. Polymethylmethacrylate has been used for augmentation of VCFs; however, there are cement complications, and long-term fracture healing is unknown. The transpedicle body augmenter (TpBA), a porous titanium spacer, has been reported as an internal support to reconstruct the vertebral body combining short segment fixation in burst fracture. We retrospectively reviewed radiographic and clinical results of TpBA vertebroplasty for single symptomatic VCF in 80 patients. Manual reduction and TpBA vertebroplasty via a paramedian incision with blunt dissection was done. Mean age was 72.3 years (range 51–87 years), and female–male ratio was 66:14. The mean symptom duration was 5 months, and follow-up 44 months. Peri-operative variables and radiographic and clinical results were evaluated. The average operation time was 26.1 min, blood loss 92 cc, and hospitalization 2.3 days. No patient had neurological deterioration. TpBA was found sinking into vertebral body initially, then locked by residual cortex, and finally stabilized within the vertebra. There was no dislodgement of TpBA in the final visit. Sixty-two patients (77.5%) could walk within 3–6 h after operation and the others within 24 h. The anterior vertebral restoration was 8.0 mm initially and 6.1 mm at final follow-up. Wedge angle correction was 11.5° initially and 9.4° at final follow-up. Pain, by the visual analog scale, was 8.6 pre-operatively, 2.5 at day 7 follow-up, and 2.9 at final follow-up. By the questionnaire, 72 of 76 respondents reported a decrease in discomfort after TpBA vertebroplasty, and 63 of 76 patients reported a return to normal activity after operation. The final satisfaction rate was 93.4%. TpBA vertebroplasty led to early and medium-term clinical improvement and anatomic restoration of painful VCFs. PMID:16957946

    Abstract Osteoporotic intertrochanteric fractures result in serious health problems and decrease health-related quality of life (HRQoL). Faster time-to-union is important for early return to daily activities and reduction of complications. Teriparatide has been shown to accelerate fracture healing, but the literature is sparse on this topic. The aim of this study is to assess whether teriparatide accelerates fracture healing. Between 2008 and 2014, patients with osteoporotic intertrochanteric fractures who underwent surgical interventions were enrolled in this retrospective cohort study. Group 1 included patients who were not on any osteoporosis medication prior to fracture and who postoperatively received only calcium and vitamin D; patients in Group 2 were not on any osteoporosis medication prior to fracture, and received teriparatide and calcium and vitamin D postoperatively. Patients in Group 3 were those who were on alendronate prior to fracture and postfracture received teriparatide as well as calcium and vitamin D. Demographics, time-to-union, HRQoL (short-form health survey [SF]-12 physical component summary [PCS] and SF-12 mental component summary [MCS]), morbidities, mortalities, and radiographic and functional outcomes between groups were compared. A total of 189 patients were enrolled in this study. There were 83 patients in Group 1, 47 patients in Group 2, and 59 patients in Group 3. A significantly shorter time-to-union was found in the teriparatide-treated groups (mean, 13.6, 12.3, and 10.6 weeks, respectively [P = 0.002]). With regard to SF-12 PCS, the scores were significantly better in teriparatide-treated groups at 3 months (mean, 19, 28, and 29, respectively [P = 0.002]) and 6 months (mean, 28, 37, and 38, respectively [P = 0.008]). Similar inter-group differences were noted when comparing the pain scores, the ability to get around the house, the ability to get out of the house, and the ability to go shopping at 3 and 6 months

    Osteoporotic intertrochanteric fractures result in serious health problems and decrease health-related quality of life (HRQoL). Faster time-to-union is important for early return to daily activities and reduction of complications. Teriparatide has been shown to accelerate fracture healing, but the literature is sparse on this topic. The aim of this study is to assess whether teriparatide accelerates fracture healing.Between 2008 and 2014, patients with osteoporotic intertrochanteric fractures who underwent surgical interventions were enrolled in this retrospective cohort study. Group 1 included patients who were not on any osteoporosis medication prior to fracture and who postoperatively received only calcium and vitamin D; patients in Group 2 were not on any osteoporosis medication prior to fracture, and received teriparatide and calcium and vitamin D postoperatively. Patients in Group 3 were those who were on alendronate prior to fracture and postfracture received teriparatide as well as calcium and vitamin D. Demographics, time-to-union, HRQoL (short-form health survey [SF]-12 physical component summary [PCS] and SF-12 mental component summary [MCS]), morbidities, mortalities, and radiographic and functional outcomes between groups were compared.A total of 189 patients were enrolled in this study. There were 83 patients in Group 1, 47 patients in Group 2, and 59 patients in Group 3. A significantly shorter time-to-union was found in the teriparatide-treated groups (mean, 13.6, 12.3, and 10.6 weeks, respectively [P = 0.002]). With regard to SF-12 PCS, the scores were significantly better in teriparatide-treated groups at 3 months (mean, 19, 28, and 29, respectively [P = 0.002]) and 6 months (mean, 28, 37, and 38, respectively [P = 0.008]). Similar inter-group differences were noted when comparing the pain scores, the ability to get around the house, the ability to get out of the house, and the ability to go shopping at 3 and 6 months.

    Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections (alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum -a major contributor to fracture healing- in the femoral neck. In extracapsular fractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.

    Background Hip fracture is often complicated by depressive symptoms in older adults. We sought to characterize trajectories of depressive symptoms arising after hip fracture and examine their relationship with functional outcomes and walking ability. We also investigated clinical and psychosocial predictors of these trajectories. Method We enrolled 482 inpatients, aged ≥60 years, who were admitted for hip fracture repair at eight St Louis, MO area hospitals between 2008 and 2012. Participants with current depression diagnosis and/or notable cognitive impairment were excluded. Depressive symptoms and functional recovery were assessed with the Montgomery–Asberg Depression Rating Scale and Functional Recovery Score, respectively, for 52 weeks after fracture. Health, cognitive, and psychosocial variables were gathered at baseline. We modeled depressive symptoms using group-based trajectory analysis and subsequently identified correlates of trajectory group membership. Results Three trajectories emerged according to the course of depressive symptoms, which we termed ‘resilient’, ‘distressed’, and ‘depressed’. The depressed trajectory (10% of participants) experienced a persistently high level of depressive symptoms and a slower time to recover mobility than the other trajectory groups. Stressful life events prior to the fracture, current smoking, higher anxiety, less social support, antidepressant use, past depression, and type of implant predicted membership of the depressed trajectory. Conclusions Depressive symptoms arising after hip fracture are associated with poorer functional status. Clinical and psychosocial variables predicted membership of the depression trajectory. Early identification and intervention of patients in a depressive trajectory may improve functional outcomes after hip fracture. PMID:27032698

    Osteoporotic hip fracture is associated with significant trabecular bone loss, which is typically characterized as low bone density by dual-energy X-ray absorptiometry (DXA) and altered microstructure by micro-computed tomography (μCT). Emerging morphological analysis techniques, e.g. individual trabecula segmentation (ITS), can provide additional insights into changes in plate-like and rod-like trabeculae, two major microstructural types serving different roles in determining bone strength. Using ITS, we evaluated trabecular microstructure of intertrochanteric bone cores obtained from 23 patients undergoing hip replacement surgery for intertrochanteric fracture and 22 cadaveric controls. Micro-finite element (μFE) analyses were performed to further understand how the abnormalities seen by ITS might translate into effects on bone strength. ITS analyses revealed that, near fracture site, plate-like trabeculae were seriously depleted in fracture patients, but trabecular rod volume was maintained. Besides, decreased plate area and rod length were observed in fracture patients. Fracture patients also showed decreased elastic moduli and shear moduli of trabecular bone. These results provided evidence that in intertrochanteric hip fracture, preferential loss of plate-like trabeculae led to more rod-like microstructure and deteriorated mechanical competence adjacent to the fracture site, which increased our understanding of the biomechanical pathogenesis of hip fracture in osteoporosis.

    Patients with systemic mastocytosis have an increased risk of osteoporosis, however, the risk of osteoporotic fractures among the classic chronic myeloproliferative neoplasms (CMPN), including essential thrombocythaemia (ET), polycythaemia vera (PV) and chronic myeloid leukaemia (CML), is unknown. We conducted a population-based cohort study to determine the risk of osteoporotic fractures among three cohorts of patients with newly diagnosed ET, PV, and CML. Patients were identified in medical registers including all Danish hospitals during 1980-2010 and were followed until first osteoporotic fracture. Fracture risk was compared to cohorts from the general population matched on age, sex and calendar year. We followed 7595 CMPN patients and 338 974 comparison cohort members. We found that the risk of femoral fracture after 5 years was consistently higher than the general population, being 3·01% (95% confidence interval (CI): 2·20-4·10), 4·74% (95%CI: 4·06-5·52) and 4·64% (95%CI: 3·29-6·53) among ET, PV, and CML patients respectively. Adjusted hazard ratio for femoral fracture was increased 1·19-fold (95% CI: 0·94-1·51) for ET patients, 1·82-fold (95% CI: 1·62-2·04) for PV patients, and 2·67-fold (95% CI: 1·97-3·62) for CML patients. We conclude that CMPN patients are at higher risk of osteoporotic fractures than the general population. PMID:24111669

    2010-01-01

    Background Today, while there are effective drugs that reduce the risk of osteoporotic fracture, yet there are no broadly accepted criteria that can be used to estimate risks and decide who should receive treatment. One of the actual priorities of clinical research is to develop a set of simple and readily-available clinical data that can be used in routine clinical practice to identify patients at high risk of bone fracture, and to establish thresholds for therapeutic interventions. Such a tool would have high impact on healthcare policies. The main objective of the ESOSVAL-R is to develop a risk prediction scale of osteoporotic fracture in adult population using data from the Region of Valencia, Spain. Methods/Design Study design: An observational, longitudinal, prospective cohort study, undertaken in the Region of Valencia, with an initial follow-up period of five years; Subjects: 14,500 men and women over the age of 50, residing in the Region and receiving healthcare from centers where the ABUCASIS electronic clinical records system is implanted; Sources of data: The ABUCASIS electronic clinical record system, complemented with hospital morbidity registers, hospital Accidents & Emergency records and the Regional Ministry of Health's mortality register; Measurement of results: Incident osteoporotic fracture (in the hip and/or major osteoporotic fracture) during the study's follow-up period. Independent variables include clinical data and complementary examinations; Analysis: 1) Descriptive analysis of the cohorts' baseline data; 2) Upon completion of the follow-up period, analysis of the strength of association between the risk factors and the incidence of osteoporotic fracture using Cox's proportional hazards model; 3) Development and validation of a model to predict risk of osteoporotic fracture; the validated model will serve to develop a simplified scale that can be used during routine clinical visits. Discussion The ESOSVAL-R study will establish a

    Osteoporotic compression spine fractures have a different clinical course and outcomes when compared to spinal fractures occurring in the younger population. Only a few studies have investigated the risk factors for progressive osteoporotic compression spine fractures. The purpose of this study was to investigate clinical and radiological factors related to progressive collapse following acute osteoporotic compression spine fractures. We retrospectively identified all patients treated for thoracolumbar fractures in our institution between January 2008 and July 2013. Included cases were examined by plain radiographs and CT scans. For each patient we classified the fracture according to the AOSpine Thoracolumbar Spine Injury Classification System. The difference between initial and final height loss and initial and final local kyphosis was documented as height loss difference and kyphotic angle difference. The presence of old fractures and intravertebral cleft were also documented. The study included 153 patients, comprising 102 women and 51 men. The mean patient age was 68.9years. The mean length of follow up was 15months. A statistically significant correlation was found between patient age, final height loss, height loss difference and kyphotic angle difference. Height loss difference and kyphotic angle difference were significantly correlated to type of fracture according to the AO classification system. The height loss difference was 18.1% in A1 type fractures, 27.1% in A2 type fractures, 24.2% in A3 type fractures and 25.7% in A4 type fractures. During a minimum 3-month follow up of conservative treatment for acute osteoporotic vertebral compression fractures, age and the AOSpine Thoracolumbar Spine Injury Classification System were predictive factors for progressive collapse.

    Context: Type 2 diabetes and osteoporosis are both common, chronic, and increase with age, whereas type 2 diabetes is also a risk factor for major osteoporotic fractures (MOFs). However, different treatments for type 2 diabetes can affect fracture risk differently, with metaanalyses showing some agents increase risk (eg, thiazolidinediones) and some reduce risk (eg, sitagliptin). Objective: To determine the independent association between new use of sitagliptin and MOF in a large population-based cohort study. Design, Setting, and Subjects: A sitagliptin new user study design employing a nationally representative Unites States claims database of 72 738 insured patients with type 2 diabetes. We used 90-day time-varying sitagliptin exposure windows and controlled confounding by using multivariable analyses that adjusted for clinical data, comorbidities, and time-updated propensity scores. Main Outcomes: We compared the incidence of MOF (hip, clinical spine, proximal humerus, distal radius) in new users of sitagliptin vs nonusers over a median 2.2 years follow-up. Results: At baseline, the median age was 52 years, 54% were men, and median A1c was 7.5%. There were 8894 new users of sitagliptin and 63 834 nonusers with a total 181 139 person-years of follow-up. There were 741 MOF (79 hip fractures), with 53 fractures (4.8 per 1000 person-years) among new users of sitagliptin vs 688 fractures (4.0 per 1000 person-years) among nonusers (P = .3 for difference). In multivariable analyses, sitagliptin was not associated with fracture (adjusted hazard ratio 1.1, 95% confidence interval 0.8–1.4; P = .7), although insulin (P < .001), sulfonylureas (P < .008), and thiazolidinedione (P = .019) were each independently associated with increased fracture risk. Conclusions: Even in a young population with type 2 diabetes, osteoporotic fractures were not uncommon. New use of sitagliptin was not associated with fracture, but other commonly used second-line agents for type 2 diabetes

    Geriatric hip fractures are one of the commonest fractures worldwide. The purpose of this study was to report the outcomes of a series of unstable geriatric hip fractures treated with AFFIXUS hip fracture nail. A retrospective study of 100 unstable geriatric hip fractures treated with AFFIXUS hip fracture nail is presented. The mean follow-up duration was 8 months (range 3–32). Of the patients 83% were female. The average age was 85 years. The fracture was treated by closed reduction and intramedullary fixation. The mean acute hospital stay was 17.6 days. Systemic complications occurred in 29 patients (29%) and local complications in 3 patients (3%) including lag screw cutout in one patient (1%), lag screw backout in one patient (1%), and deep infection in one patient (1%). Mechanical failures and periprosthetic fractures were not observed in our series. Fractures united in all patients. Preinjury activity level was recovered in 78% of the patients. The results of AFFIXUS hip fracture nail were satisfactory in most elderly patients. The unique design of the lag screw and its thread spacing had effectively reduced cut-out rate. PMID:25580303

    Background and purpose - Pre-fracture functional level has been shown to be a consistent predictor of rehabilitation outcomes in older hip fracture patients. We validated 4 overall pre-fracture functional level assessment instruments in patients aged 65 or more, used the prediction of outcome at 4 months post-fracture, and assessed cutoff values for decision making in treatment and rehabilitation. Patients and methods - 165 consecutive patients with acute primary hip fracture were prospectively included in the study. Pre-fracture Barthel-20, Barthel-100, cumulated ambulation score, and new mobility score were scored immediately after admission. Outcome defined as mortality, residential status, and independent walking ability was assessed at 4 months. Results - 3 of the assessment instruments, namely Barthel-20, Barthel-100, and new mobility score, correlated with outcome at 4 months post-fracture and were valid predictors. Thresholds were estimated. We found no evidence that Barthel-100, with its finer granularity, performs better than Barthel-20 as a predictor. Interpretation - Our findings indicate that pre-fracture scores of Barthel-20 and new mobility score have predictive ability, and further investigation of usage for guidance of clinical and rehabilitation decisions concerning hip fracture patients is warranted.

    Purpose While current osteoporosis management guidelines recommend use of pharmacologic treatment following hip fracture, the care of such patients has been suboptimal. The objective of this cross-national study is to quantify the use of and adherence to osteoporosis medication following hip fracture in three countries with different health care systems- the United States, Korea and Spain. Methods In three cohorts of patients aged ≥65 years hospitalized for hip fracture, we calculated the proportion receiving ≥1 osteoporosis drug after discharge. Adherence to osteoporosis treatment was measured as the proportion of days covered (PDC) during the first year following the hip fracture. Results We identified 86,202 patients with a hip fracture - 4,704 (U.S. Medicare), 6,700 (U.S. commercial), 57,631(Korea), and 17,167 (Spain). The mean age was 77–83 years and 74–78% were women. In the year prior to the index hip fracture, 16–18% were taking an osteoporosis medication. Within 3 months following the index hip fracture, 11% (U.S. Medicare), 13% (U.S. commercial), 39% (Korea), and 25% (Spain) of patients filled ≥1 prescription for osteoporosis medication. For those who filled one or more prescriptions for an osteoporosis medication, the mean PDC in the year following the fracture was 0.70 (U.S. Medicare), 0.67 (U.S. commercial), 0.43 (Korea) and 0.66 (Spain). Conclusions Regardless of differences in health care delivery systems and medication reimbursement plans, the use of osteoporosis medications for the secondary prevention of osteoporotic fracture was low. Adherence to osteoporosis treatment was also suboptimal with the PDC<0.70 in all three countries. PMID:25660252

    Several studies have shown a long-lasting higher mortality after hip fracture, but the reasons for the excess risk are not well understood. We aimed to determine whether a higher mortality after hip fracture exists when controlling for genetic constitution, shared environment, comorbidity, and lifestyle by use of a nationwide cohort study in hip fracture discordant monozygotic twins. All 286 identical Swedish twin pairs discordant for hip fracture (1972 to 2010) were identified. Comorbidity and lifestyle information was retrieved by registers and questionnaire information. We used intrapair Cox regression to compute multivariable-adjusted hazard ratios (HRs) for death. During follow-up, 143 twins with a hip fracture died (50%) compared with 101 twins (35%) without a hip fracture. Through the first year after hip fracture, the rate of death increased fourfold in women (HR = 3.71; 95% confidence interval [CI] 1.32-10.40) and sevenfold in men (HR = 6.67; 95% CI 1.47-30.13). The increased rate in women only persisted during the first year after hip fracture (HR after 1 year = 0.99; 95% CI 0.66-1.50), whereas the corresponding HR in men was 2.58 (95% CI 1.02-6.62). The higher risk in men after the hip fracture event was successively attenuated during follow-up. After 5 years, the hazard ratio in men with a hip fracture was 1.19 (95% CI 0.29-4.90). On average, the hip fracture contributed to 0.9 years of life lost in women (95% CI 0.06-1.7) and 2.7 years in men (95% CI 1.7-3.7). The potential years of life lost associated with the hip fracture was especially pronounced in older men (>75 years), with an average loss of 47% (95% CI 31-61) of the expected remaining lifetime. We conclude that both women and men display a higher mortality after hip fracture independent of genes, comorbidity, and lifestyle. PMID:23821464

    OBJECTIVES To determine whether circadian activity rhythms are associated with mortality in community-dwelling older women. DESIGN Prospective study of mortality. SETTING A cohort study of health and aging. PARTICIPANTS 3,027 community-dwelling women from the Study of Osteoporotic Fractures cohort (mean age 84 years). MEASUREMENTS Activity data were collected with wrist actigraphy for a minimum of three 24-hour periods and circadian activity rhythms were computed. Parameters of interest included height of activity peak (amplitude), mean activity level (mesor), strength of activity rhythm (robustness), and time of peak activity (acrophase). Vital status, with cause of death adjudicated through death certificates, was prospectively ascertained. RESULTS Over an average of 4.1 years of follow-up there were 444 (15%) deaths. There was an inverse association between peak activity height and all-cause mortality rates with higher mortality rates observed in the lowest activity quartile (Hazard ratio [HR]=2.18, 95% CI, 1.63–2.92) compared with the highest quartile after adjusting for age, clinic site, race, BMI, cognitive function, exercise, IADL impairments, depression, medications, alcohol, smoking, self-reported health status, married status, and co-morbidities. Increased risk of all-cause mortality was observed between lower mean activity level (HR=1.71, 95% CI, 1.29–2.27) and rhythm robustness (HR=1.97, 95% CI, 1.50–2.60). Increased mortality from cancer (HR=2.09, 95% CI, 1.04–4.22) and stroke (HR=2.64, 95% CI, 1.11–6.30) was observed for a delayed timing of peak activity (after 4:33PM; >1.5 SD from mean) when compared to the mean peak range (2:50PM–4:33PM). CONCLUSION Older women with weak circadian activity rhythms have higher mortality risk. If confirmed in other cohorts, studies will be needed to test whether interventions (e.g. physical activity, bright light exposure) that regulate circadian activity rhythms will improve health outcomes in the elderly

    More severe hip fractures such as displaced femoral neck (FN) fractures and unstable intertrochanteric (IT) fractures lead to poorer outcomes, but risk factors for severe fractures have not been studied. To identify risk factors for severe types of hip fracture, we performed a prospective cohort study and obtained preoperative hip radiographs from women who sustained an incident hip fracture (excluding traumatic fractures). A single radiologist scored the severity of FN fractures by the Garden System: grades I and II, undisplaced; grades III and IV, displaced. The severity of IT hip fractures was rated by the Kyle System: grades I and II, stable; grades III and IV, unstable. A total of 249 women had FN fractures: 75 (30%) were undisplaced. A total of 213 women had IT fractures: 59 (28%) were stable. Both types of hip fracture increased with age, but older age was even more strongly associated with more severe hip fractures. Low BMD was more strongly related to undisplaced FN fractures (p interaction BMD × FN type, p = 0.0008) and stable IT fractures (p interaction BMD × IT type, p = 0.04). Similar findings were observed for estimated volumetric BMD and hip geometric parameters. Corticosteroid use was only associated with displaced FN fractures, and Parkinson's disease was only associated with stable IT fractures. Little difference was reported in the self-reported circumstances surrounding each type of fracture. In conclusion, the lower the BMD, the greater the likelihood of experiencing a hip fracture that is less displaced and more stable. PMID:19113930

    Abstract The increasing problems in the field of osteoporotic fracture fixation results in specialized implants as well as new operation methods, for example, implant augmentation with bone cement. The aim of this study was to determine the biomechanical impact of augmentation in the treatment of osteoporotic distal femur fractures. Seven pairs of osteoporotic fresh frozen distal femora were randomly assigned to either an augmented or nonaugmented group. In both groups, an Orthopaedic Trauma Association 33 A3 fractures was fixed using the locking compression plate distal femur and cannulated and perforated screws. In the augmented group, additionally, 1 mL of polymethylmethacrylate cement was injected through the screw. Prior to mechanical testing, bone mineral density (BMD) and local bone strength were determined. Mechanical testing was performed by cyclic axial loading (100 N to 750 N + 0.05N/cycle) using a servo-hydraulic testing machine. As a result, the BMD as well as the axial stiffness did not significantly differ between the groups. The number of cycles to failure was significantly higher in the augmented group with the BMD as a significant covariate. In conclusion, cement augmentation can significantly improve implant anchorage in plating of osteoporotic distal femur fractures. PMID:25415673

    Purpose This study examined the role of trace elements in osteoporosis by comparing the trace-element concentrations in bone and the radiographic bone density and bone mineral density (BMD) of patients with osteoporotic femur fractures and osteoarthritis. Patients and methods The study enrolled 30 patients operated on for proximal femoral fractures after falls, and another 30 patients undergoing hip arthroplasty at the same center for hip osteoarthritis. Bone samples were obtained during the surgical procedures. The density of the bone samples was assessed using computed tomography and the Hounsfield scale. The levels of Ca(II), Mg(II), and other trace elements in the bone samples were determined using flame atomic absorption spectrometry and inductively coupled plasma mass spectrometry. In addition, BMD, Z-scores, and T-scores were measured in the unaffected hips of all patients using dual-energy X-ray absorptiometry. Results Magnesium (1,908±507 versus 2,540±435, P<0.05), calcium (10.4±3.5 versus 13.9±3.7, P<0.05), and zinc (2,342±1,252 versus 3,145±1,604, P<0.05) μg g−1, levels were significantly lower in the bone samples in the fracture group. The groups did not differ in the other biochemical parameters. All dual-energy X-ray absorptiometry findings were significantly worse in the fracture group than in the osteoarthritis group. However, the groups did not differ in femoral neck density assessed radiologically using the Hounsfield scale. The following parameters were negatively correlated with age: magnesium, r=−0.436, P<0.001; calcium, r=−0.331, P=0.01; T-score, r=−0.381, P=0.003; Z-score, r=−0.267, P=0.043; and BMD, r=−0.365, P=0.004. Conclusion Ca(II), Mg(II), and Zn(II) appear to play important roles in bone breakdown/synthesis. Further studies of the roles of trace elements in the etiology and treatment of osteoporosis are warranted. We found decreased bone levels of Ca, Mg, and Zn in patients with osteoporotic fractures compared to

Fractures of the distal humerus can be treated in a closed or open fashion. Open treatment includes open reduction and internal fixation or total elbow arthroplasty. Open reduction and internal fixation typically involves dual plating for increased stability and early mobility. We present a case in which dual plating failed due to lack of screw purchase in osteoporotic bone. This patient’s fracture was then revised with the use of a fibular strut allograft for improved stability and screw purchase. This method of fixation has not previously been described in the distal humerus and may prove useful in open fixation of osteoporotic distal humerus fractures. PMID:23569712

    Introduction: Sustaining an intracapsular fracture in a hip which was previously fixed with dynamic hip screw for extracapsular fracture, is a very rarely reported occurrence. We present one such case in order to discuss the presentation and management of this fracture. We have also reviewed the literature and pooled the previously reported cases to look at potential cause & risk factors. Case Report: A 92 year old female, presented with new onset hip pain following a trivial injury. Couple of years back, she had sustained an extracapsular fracture on same side which was treated by DHS fixation. Further investigations confirmed a de-novo fracture which was treated by removal of DHS and cemented bipolar hemiarthroplasty. Conclusion: This complication might not be as rare as earlier thought to be. All patients, especially elderly females who present with new onset hip pain following DHS fixation of their hip fracture previously must be evaluated for a de-novo intracapsular fracture. On confirmation of diagnosis, they can be treated by removal of dynamic hip screw and hemiarthroplasty as most of these are low demand elderly patients. PMID:27299034

    Vertebral fractures due to osteoporosis are a common skeletal disorder affecting the mobility of the patients, although little is known about the relationship between spinal kinematics and osteoporotic fracture. The purpose of this study was to characterize the motions of the thoracolumbar spine affected by osteoporotic vertebral fracture at level T12 and compare the results with those of non-fracture osteoporosis subjects. We examined the continuous segmental kinematics of the vertebrae, and describe the segmental motion of the spine when a fracture at T12 is present. Fluoroscopy sequences of the thoracolumbar spines during sagittal and lateral flexion were collected from 16 subjects with osteoporosis of their spine (6 with vertebral fractures at T12, 10 without a fracture). Vertebrae T10-L2 in each frame of the sequences were landmarked. Kinematic parameters were calculated based on the landmarks and motion graphs were constructed. Compared to the control subjects who did not have a fracture, fracture subjects had a more asymmetric lateral range of motion (RoM) and required a longer time to complete certain phases of the motion cycle which are parameterized as lateral flexion ratio and percentage of motion cycle, respectively. Prolonged deflection was more frequently found from the fracture group. Characterizing the motions of the fractured vertebra together with its neighboring vertebrae with these kinematic parameters is useful in quantifying the dysfunction and may be a valuable aid to tracking progress of treatment.

    OBJECTIVES To examine the effect of the relationship between volume (number of hip fracture admissions during the 12 months before participant’s fracture) and other facility characteristics on outcomes. DESIGN Prospective observational study. SETTING U.S. skilled nursing facilities (SNFs) admitting individuals discharged from the hospital after treatment for hip fracture between 2000 and 2007 (N = 15,439). PARTICIPANTS Community-dwelling fee-for-service Medicare beneficiaries aged 75 and older admitted to U.S. hospitals for their first hip fracture and discharged to a SNF for postacute care from 2000 to 2007 (N = 512,967). MEASUREMENTS Successful discharge from SNF to community, defined as returning to the community within 30 days of hospital discharge to the SNF and remaining in the community without being institutionalized for at least 30 days, was examined using Medicare administrative data, propensity score matching, and instrumental variables. RESULTS The overall rate of successful discharge to the community was 31%. Of the 15,439 facilities, the facility interquartile range varied from 0% (25th percentile) to 42% (75th percentile). An important determinant of variation in discharge rate was SNF volume of hip fracture admissions. Unadjusted successful discharge from SNF to community was 43.7% in high-volume facilities (>24 admissions/year), versus 18.8% in low-volume facilities (1–6 admissions/year). This facility volume effect persisted after adjusting for participant and facility characteristics associated with outcomes (e.g., adjusted odds ratio = 2.06, 95% confidence interval = 1.91–2.21 for volume of 25 vs 3 admissions per year). CONCLUSION In community-dwelling persons with their first hip fracture, successful return to the community varies substantially according to SNF provider volume and staffing characteristics.

    Many risk factors have been identified for hip fracture, including female, advanced age, osteoporosis, previous fractures, low body weight or low body mass index, alcohol drinking, smoking, family history of fractures, use of glucocorticoid, factors related to falls, and bone strength. The factors related to falls are number of fall, frail, post stroke, paralysis, muscle weakness, anti-anxiety drugs, anti-depression drugs, and sedatives. Dementia and respiratory disease and others have been reported to be risk factors for secondary hip fracture. PMID:25814010

    Hip fracture, a significant health issue for older adults, is an acute event in which older adults can recover their prefracture functional abilities. The recovery phase is often difficult for older adults, and the role of informal caregivers is particularly important. The aim of this qualitative study was to explore informal caregivers' experiences with providing care to older adults over the first 6-month trajectory of hip fracture recovery and their support needs. Participants (N = 10) were interviewed twice at 0–2 and 5–6 months. Analyses of the verbatim transcripts revealed multiple shared themes. Some themes were consistent across phases, such as hip fracture as a turning point toward a frailer state, feeling tired, frustration with communication issues in health care delivery, and lack of information about caregiving-related activities. Certain themes were phase-specific. For instance, in the early phase, management of hospital bills and transitions between care settings were especially burdensome. The caregiving situation, however, was viewed as an opportunity to spend more time with their loved ones. Findings from this study revealed unmet support needs expressed by caregivers of older adult hip fracture patients. Ongoing research and clinical interventions are needed to establish effective methods to empower these caregivers. PMID:20682403

    There is a high rate of mortality in elderly patients who sustain a fracture of the hip. We aimed to determine the rate of preventable mortality and errors during the management of these patients. A 12 month prospective study was performed on patients aged > 65 years who had sustained a fracture of the hip. This was conducted at a Level 1 Trauma Centre with no orthogeriatric service. A multidisciplinary review of the medical records by four specialists was performed to analyse errors of management and elements of preventable mortality. During 2011, there were 437 patients aged > 65 years admitted with a fracture of the hip (85 years (66 to 99)) and 20 died while in hospital (86.3 years (67 to 96)). A total of 152 errors were identified in the 80 individual reviews of the 20 deaths. A total of 99 errors (65%) were thought to have at least a moderate effect on death; 45 reviews considering death (57%) were thought to have potentially been preventable. Agreement between the panel of reviewers on the preventability of death was fair. A larger-scale assessment of preventable mortality in elderly patients who sustain a fracture of the hip is required. Multidisciplinary review panels could be considered as part of the quality assurance process in the management of these patients. Cite this article: Bone Joint J 2014;96-B:1178–84. PMID:25183587

    Objective The aim of the study was to evaluate factors influencing quality of life (QOL) in Moroccan postmenopausal women with osteoporotic vertebral fracture assessed by the Arabic version of ECOS 16 questionnaire. Methods 357 postmenopausal women were included in this study. The participants underwent bone mineral density (BMD) measurements by DXA of the lumbar spine and the total hip as well as X-ray examination of the thoraco-lumbar spine to identify subclinical vertebral fractures. Patients were asked to complete a questionnaire on clinical and sociodemographic parameters, and osteoporosis risk factors. The Arabic version of the ECOS16 (Assessment of health related quality of life in osteoporosis questionnaire) was used to assess quality of life. Results The mean age was 58 ± 7.8 years, and the mean BMI was 28.3 ± 4.8 kg/m2. One hundred and eight women (30.1%) were osteoporotic and 46.7% had vertebral fractures. Most were categorized as Grade1 (75%). Three independent factors were associated with a poor quality of life: low educational level (p = 0,01), vertebral fracture (p = 0,03), and history of peripheral fracture (p = 0,006). Worse QOL was observed in the group with vertebral fracture in all domains except "pain": Physical functioning (p = 0,002); Fear of illness (p = 0,001); and Psychosocial functioning (p = 0,007). The number of fractures was a determinant of a low QOL, as indicated by an increased score in physical functioning (p = 0,01), fear of illness (p = 0,007), and total score (p = 0,01) after adjusting on age and educational level. Patients with higher Genant score had low QOL in these two domains too (p = 0,002; p = 0,001 respectively), and in the total score (p = 0,01) after adjusting on age and educational level. Conclusion Our current data showed that the quality of life assessed by the Arabic version of the ECOS 16 questionnaire is decreased in post menopausal women with prevalent vertebral fractures, with the increasing number and the

    DDR2 gene, playing an essential role in regulating osteoblast differentiation and chondrocyte maturation, may influence bone mineral density (BMD) and osteoporosis, but the genetic variations actually leading to the association remain to be elucidated. Therefore, the aim of this study was to investigate whether the genetic variants in DDR2 are associated with BMD and fracture risk. This study was performed in three samples from two ethnicities, including 1,300 Chinese Han subjects, 700 Chinese Han subjects (350 with osteoporotic hip fractures and 350 healthy controls) and 2,286 US white subjects. Twenty-eight SNPs in DDR2 were genotyped and tested for associations with hip BMD and fractures. We identified 3 SNPs in DDR2 significantly associated with hip BMD in the Chinese population after multiple testing adjustments, which were rs7521233 (P = 1.06×10−4, β: −0.018 for allele C), rs7553831 (P = 1.30×10−4, β: −0.018 for allele T), and rs6697469 (P = 1.59×10−3, β: −0.015 for allele C), separately. These three SNPs were in high linkage disequilibrium. Haplotype analyses detected two significantly associated haplotypes, including one haplotype in block 2 (P = 9.54×10−4, β: −0.016) where these three SNPs located. SNP rs6697469 was also associated with hip fractures (P = 0.043, OR: 1.42) in the Chinese population. The effect on fracture risk was consistent with its association with lower BMD. However, in the white population, we didn’t observe significant associations with hip BMD. eQTL analyses revealed that SNPs associated with BMD also affected DDR2 mRNA expression levels in Chinese. Our findings, together with the prior biological evidence, suggest that DDR2 could be a new candidate for osteoporosis in Chinese population. Our results also reveal an ethnic difference, which highlights the need for further genetic studies in each ethnic group. PMID:25658585

  9. Multimodal Analgesia in the Hip Fracture Patient.

    Hip fracture is one of the most common injuries among the elderly and, because the population is aging, it is expected to remain a major clinical challenge and public health problem for the foreseeable future. The clinical importance of early mobilization and prompt participation in physical therapy after hip fracture surgery is now widely recognized. Because postoperative pain can impair mobility and delay physical therapy, much attention is now being paid to finding more effective ways of controlling pain after hip fracture. Oversedation with opioid drugs inhibits communication between the patient and the health care team, can delay ambulation and rehabilitation therapy, and may increase the probability of the patient requiring a skilled nursing facility, which adds further cost to the overall health care system. Multiple pain pathways contribute to the perception of postoperative pain, and although opioids are highly effective in blocking nociceptive pain through inhibition of the mu receptors, they do not block other pain pathways. Multimodal analgesia involves the use of several anesthetic and analgesic modalities that are strategically combined to block pain perception at different sites in the peripheral and central nervous systems. This balanced, multifaceted approach provides more effective control of postoperative pain than opioid drugs alone, allows lower doses of opioids to be used as part of the multimodal regimen (thereby reducing the risk of opioid-related adverse events and complications), and may facilitate more rapid recovery and improve certain outcome measures related to recovery time. One prospective randomized study evaluating the clinical value of multimodal pain management in elderly patients undergoing bipolar hip hemiarthroplasty found that a multimodal regimen, including preemptive pain medication and intraoperative periarticular injections, reduced pain on postoperative days 1 and 4, and reduced overall opioid use.

    Osteoporosis is often underdiagnosed and undertreated. Screening of post-menopausal women for clinical risk factors and/or low bone mineral density (BMD) has been proposed to overcome this. Digital X-ray radiogrammetry (DXR) estimates hand BMD from standard hand X-ray images and have shown to predict fractures and osteoporosis. Recently, digital radiology and the internet have opened up the possibility of conducting automated opportunistic screening with DXR in post-fracture care or in combination with mammography. This study compared the performance of DXR with FRAX® and DXA in discriminating major osteoporotic fracture (MOF) (hip, clinical spine, forearm or shoulder), hip fracture and femoral neck osteoporosis. This prospective cohort study was conducted on 5278 women 65years and older in the Study of Osteoporotic Fractures (SOF) cohort. Baseline hand X-ray images were analyzed and fractures were ascertained during 10years of follow up. Age-adjusted area under receiver operating characteristic curve (AUC) for MOF and hip fracture and for femoral neck osteoporosis (DXA FN BMD T-score ≤-2.5) was used to compare the methods. Sensitivity to femoral neck osteoporosis at equal selection rates was tabulated for FRAX and DXR. DXR-BMD, FRAX (no BMD) and lumbar spine DXA BMD were all similar in fracture discriminative performance with an AUC around 0.65 for MOF and 0.70 for hip fractures for all three methods. As expected femoral neck DXA provided fracture discrimination superior both to other BMD measurements and to FRAX. AUC for selection of patients with femoral neck osteoporosis was higher with DXR-BMD, 0.76 (0.74-0.77), than with FRAX, 0.69 (0.67-0.71), (p<0.0001). In conclusion, DXR-BMD discriminates incident fractures to a similar degree as FRAX and predicts femoral neck osteoporosis to a larger degree than FRAX. DXR shows promise as a method to automatically flag individuals who might benefit from an osteoporosis assessment. PMID:26921822

    Insertion of bone substitution materials accelerates healing of osteoporotic fractures. Biodegradable materials are preferred for application in osteoporotic patients to avoid a second surgery for implant replacement. Degraded implant fragments are often absorbed by macrophages that are removed from the fracture side via passage through veins or lymphatic vessels. We investigated if lymphatic vessels occur in osteoporotic bone defects and whether they are regulated by the use of different materials. To address this issue osteoporosis was induced in rats using the classical method of bilateral ovariectomy and additional calcium and vitamin deficient diet. In addition, wedge-shaped defects of 3, 4, or 5 mm were generated in the distal metaphyseal area of femur via osteotomy. The 4 mm defects were subsequently used for implantation studies where bone substitution materials of calcium phosphate cement, composites of collagen and silica, and iron foams with interconnecting pores were inserted. Different materials were partly additionally functionalized by strontium or bisphosphonate whose positive effects in osteoporosis treatment are well known. The lymphatic vessels were identified by immunohistochemistry using an antibody against podoplanin. Podoplanin immunopositive lymphatic vessels were detected in the granulation tissue filling the fracture gap, surrounding the implant and growing into the iron foam through its interconnected pores. Significant more lymphatic capillaries were counted at the implant interface of composite, strontium and bisphosphonate functionalized iron foam. A significant increase was also observed in the number of lymphatics situated in the pores of strontium coated iron foam. In conclusion, our results indicate the occurrence of lymphatic vessels in osteoporotic bone. Our results show that lymphatic vessels are localized at the implant interface and in the fracture gap where they might be involved in the removal of lymphocytes, macrophages

    Objective: To determine the pathogenesis and characteristics and to assess the long-term effectiveness of polymethylmethacry late (PMMA) vertebroplasty treatment in patients with intravertebral cleft (IVC) in osteoporotic compression fractures. Methods: A retrospective analysis of radiological and clinical parameters was performed on 388 patients who underwent percutaneous vertebroplasty or kyphoplasty to treat osteoporotic compression fractures from January 2010 to October 2012. IVC sign was observed in the MRI of 47 patients. Postoperative follow-ups were conducted for at least 2 years after surgery. Results: IVC incidence was associated with older age and lower bone mineral density. Other baseline measurements, such as preoperative visual analogue scale and Oswestry Disability Index (ODI), showed no significant difference between IVC and non-IVC fracture patients. Vertebral height and kyphotic angle were corrected after percutaneous vertebroplasty or kyphoplasty with no significant difference in outcome between the two procedures. Restored vertebral height collapsed and the kyphotic angle became aggravated during the 2 years following surgery in patients with IVC. Similarly, initial improvements in visual analogue scale and ODI decreased over time. Non-IVC patients’ had a slight recurrence of compression and kyphosis that began to normalize after 1 year. Visual analogue scale and ODI at 2 years’ post-surgery was also significantly lower in non-IVC than IVC patients. Conclusion: Polymethylmethacrylate vertebroplasty treatment of osteoporotic compression fractures is initially effective for patients with signs of IVC, but compression and kyphosis gradually reoccur. Therefore, we strongly recommend strict observation and follow-up after vertebroplasty. PMID:26629251

    Background: The aim of the study was to refine current evaluation systems used to assess outcome after a hip fracture and to devise a simple and practical system to assess all hip fracture patients. Methods: Three continuous scales were defined for pain, mobility and functional independence. These were all found to have an acceptable degree of inter-observer agreement. The pre-fracture mobility and independence scores were related to the one-year mortality for a consecutive series of 381 patients. Results: Scores for mobility and functional independence were highly predictive of mortality (p < 0.0001). Conclusions: It is recommended that the outcome after hip fracture should be standardised to these principle outcomes of pain, regain of mobility and independence and mortality. These scores can be use to assess progress and identify those who may require additional assessment or intervention. PMID:27259572

    Osteoporosis is the consequence of altered bone metabolism resulting in the systemic reduction of bone strength and increased risk of fragility fractures. MicroRNAs (miRNAs) regulate gene expression on a post-transcriptional level and are known to take part in the control of bone formation and bone resorption. In addition, it is known that miRNAs are secreted by many cell types and can transfer "messages" to recipient cells. Thus, circulating miRNAs might not only be useful as surrogate biomarkers for the diagnosis or prognosis of pathological conditions, but could be actively modulating tissue physiology. Therefore, the aim of this study was to test whether circulating miRNAs that exhibit changes in recent osteoporotic fracture patients could be causally related to bone metabolism. In the first step we performed an explorative analysis of 175 miRNAs in serum samples obtained from 7 female patients with recent osteoporotic fractures at the femoral neck, and 7 age-matched female controls. Unsupervised cluster analysis revealed a high discriminatory power of the top 10 circulating miRNAs for patients with recent osteoporotic fractures. In total 6 miRNAs, miR-10a-5p, miR-10b-5p, miR-133b, miR-22-3p, miR-328-3p, and let-7g-5p exhibited significantly different serum levels in response to fracture (adjusted p-value<0.05). These miRNAs were subsequently analyzed in a validation cohort of 23 patients (11 control, 12 fracture), which confirmed significant regulation for miR-22-3p, miR-328-3p, and let-7g-5p. A set of these and of other miRNAs known to change in the context of osteoporotic fractures were subsequently tested for their effects on osteogenic differentiation of human mesenchymal stem cells (MSCs) in vitro. The results show that 5 out of 7 tested miRNAs can modulate osteogenic differentiation of MSCs in vitro. Overall, these data suggest that levels of specific circulating miRNAs change in the context of recent osteoporotic fractures and that such perturbations of

    We compared a minimally invasive surgical technique to the conventional (open approach) surgical technique used in fixation of hip fractures with the dynamic hip screw (DHS) device. Using a case-control design (44 cases and 44 controls), we tested the null hypothesis that there is no difference between the two techniques in the following outcome measures: duration of surgery, time to mobilisation and weight bearing postoperatively, length of hospital stay, mean difference of pre- and postoperative haemoglobin levels, position of the lag screw of the DHS device in the femoral head, and the tip–apex distance. The minimally invasive DHS technique had significantly shorter duration of surgery and length of hospital stay. There was also less blood loss in the minimally invasive DHS technique. The minimally invasive DHS technique produces better outcome measures in the operating time, length of hospital stay, and blood loss compared to the conventional approach while maintaining equal fixation stability.

    Clinical implementation of quantitative computed tomography-based finite element analysis (QCT/FEA) of proximal femur stiffness and strength to assess the likelihood of proximal femur (hip) fractures requires a unified modeling procedure, consistency in predicting bone mechanical properties, and validation with realistic test data that represent typical hip fractures, specifically, a sideways fall on the hip. We, therefore, used two sets (n = 9, each) of cadaveric femora with bone densities varying from normal to osteoporotic to build, refine, and validate a new class of QCT/FEA models for hip fracture under loading conditions that simulate a sideways fall on the hip. Convergence requirements of finite element models of the first set of femora led to the creation of a new meshing strategy and a robust process to model proximal femur geometry and material properties from QCT images. We used a second set of femora to cross-validate the model parameters derived from the first set. Refined models were validated experimentally by fracturing femora using specially designed fixtures, load cells, and high speed video capture. CT image reconstructions of fractured femora were created to classify the fractures. The predicted stiffness (cross-validation R2 = 0.87), fracture load (cross-validation R2 = 0.85), and fracture patterns (83% agreement) correlated well with experimental data. PMID:21052839

Methods Thirty-two patients at a mean age of 92.8 (±2.7) were treated in a single institution and reported at a mean follow-up of 2.02 (±1.35) years. Results Mortality was similar between proximal femoral nailing (PFN) and bipolar cemented hemiarthroplasty (BCH) in first year (p = 0.17) but significantly high in following years in BCH (p = 0.035) and patients with cardiac disease (p = 0.054). Conclusion Hip fractures are challenging in extremely old patients and associated with increased mortality and disability. PMID:25264408

    Osteoporotic hip fracture needs a specific approach and treatment, since elderly patients are at high risk for adverse outcomes after surgery. In particular, delirium often occurs in the peri-operative period, and it is associated with death, hospital-acquired complications, persistent cognitive impairments, poor functional recovery after surgery and increased healthcare costs. The pre-operative assessment of the risk factors for delirium improves the preventive measures. The delirium diagnostic tools should be included in the standard of orthogeriatric cure for hip fracture. Given the increasing complexity of the clinical pictures, we present a review of the available treatment options for delirium in patients with hip fracture. The metabolic pre-operative disorders and the management of co-morbid diseases are specific targets of treatment in order to optimize the outcomes after surgery. In particular, elderly patients with Alzheimer's disease are highly vulnerable to hip fracture and delirium, and they are severely frail with reduced physiologic reserves. An integrated approach combining environmental and pharmacological strategies is useful in the delirium treatment, with a close collaboration between the orthopedic and geriatric team. PMID:25687439

    Osteoporosis is associated with delayed and/or reduced fracture healing. As cervus and cucumis are the traditional Chinese treatments for rheumatoid arthritis, we investigated the effect of supplementation of these peptides (CCP) on bone fracture healing in ovariectomized (OVX) osteoporotic rats in vitro and in vivo. CCP enhanced osteoblast proliferation and increased alkaline phosphatase activity, matrix mineralization, and expression of runt-related transcription factor 2 (Runx2), bone morphogenetic protein 4 (BMP4), and osteopontin. In vivo, female Sprague-Dawley rats underwent ovariectomy and the right femora were fractured and fixed by intramedullary nailing 3 months later. Rats received intraperitoneal injections of either CCP (1.67 mg/kg) or physiological saline every day for 30 days. Fracture healing and callus formation were evaluated by radiography, micro-CT, biomechanical testing, and histology. At 12 weeks after fracture, calluses in CCP-treated bones showed significantly higher torsional strength and greater stiffness than control-treated bones. Bones in CCP-treated rats reunified and were thoroughly remodeled, while two saline-treated rats showed no bone union and incomplete remodeling. Taken together, these results indicate that use of CCP after fracture in osteoporotic rats accelerates mineralization and osteogenesis and improves fracture healing. PMID:25525453

    Background: Intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. Dynamic Hip Screw (DHS) is still considered the gold standard for treating intertrochanteric fractures by many. Not many studies compare the DHS with Proximal femoral nail (PFN), in Type II intertrochanteric fractures (Boyd and Griffin classification). This study was done to compare the functional and radiological outcome of PFN with DHS in treatment of Type II intertrochanteric fractures. Methods: From October 2012 to March 2015, a prospective comparative study was done where 30 alternative cases of type II intertrochanteric fractures of hip were operated using PFN or DHS. Intraoperative complications were noted. Functional outcome was assessed using Harris Hip Score and radiological findings were compared at 3, 6, and 12 months postoperatively. Results: The average age of the patients was 60 years. In our series we found that patients with DHS had increased intraoperative blood loss (159ml), longer duration of surgery (105min), and required longer time for mobilization while patients who underwent PFN had lower intraoperative blood loss (73ml), shorter duration of surgery (91min), and allowed early mobilization. The average limb shortening in DHS group was 9.33 mm as compared with PFN group which was only 4.72 mm. The patients treated with PFN started early ambulation as they had better Harris Hip Score in the early post-op period. At the end of 12th month, there was not much difference in the functional outcome between the two groups. Conclusion: PFN is better than DHS in type II intertrochanteric fractures in terms of decreased blood loss, reduced duration of surgery, early weight bearing and mobilization, reduced hospital stay, decreased risk of infection and decreased complications.

    Percutaneous vertebroplasty has been performed for more than ten years to treat painful osteoporotic vertebral compression fractures. Clinical results have been encouraging, but little is known about the efficacy and safety of this minimally invasive procedure. We therefore performed a systematic review to assess the efficacy and safety of percutaneous vertebroplasty in osteoporotic vertebral compression fractures. A search was conducted using Medline, Embase and The Cochrane Controlled Trials Register. The search yielded fifteen studies, eleven prospective, three retrospective and one controlled trial. Totally 1,136 interventions were performed on 793 patients. Mean pain scores, measured using a 0 to 10 VAS score, improved significantly from 7.8 to 3.1 (-60.3%) immediately after percutaneous vertebroplasty. The short-term complication rate varied between 0.4 and 75.6%. Leakage of cement outside the vertebral body was markedly common, ranging from 3.3 to 75.6%. Although the majority was asymptomatic, a few devastating clinical adverse effects were reported (mean 2.4%). Although percutaneous vertebroplasty is a widely accepted treatment for osteoporotic vertebral fractures, we revealed only a single controlled trial. We conclude that there are insufficient data available to reliably assess efficacy of percutaneous vertebroplasty. The procedure has a low rate of clinical complications, but potential complications can be devastating. In the future, assessing the efficacy of percutaneous vertebroplasty requires controlled trials with long-term follow-up. PMID:16823557

    Background Inadequate calcium and vitamin D intake is a possible risk factor of osteoporosis. Our purposes were to estimate calcium and vitamin D intake in women with osteoporotic fractures, to determine associated factors for low calcium and vitamin D intake, and to evaluate the effects of calcium and vitamin D intake on bone mineral density (BMD). Methods This is a multicenter, hospital-based, and cross-sectional study involving 277 women with osteoporotic fractures. Dietary calcium and vitamin D intake were evaluated using the Korean Calcium Assessment Tool (KCAT) self-reported questionnaire. BMD was measured by dual energy X-ray absorptiometry (DXA) in the lumbar spine and femoral neck. Results Average daily calcium and vitamin D intake was 503.7±274.7 mg and 7.5±12.6 µg, respectively. Patients with low calcium intake had less family history of osteoporosis and were older. There was a negative correlation between age and calcium intake (r=-0.14; P=0.019). In multivariate analysis, calcium intake showed a positive correlation with BMD of femoral neck (β=0.0005, P=0.021). Conclusions About 80% of patients with osteoporotic fracture had calcium and vitamin D intake below the recommended dietary intake. Low calcium intake was associated with no family history of osteoporosis and older age. Dietary calcium intake showed positive effect on BMD. PMID:27294077

    Objective: To evaluate the clinical therapeutic effects of anterior decompression on spinal osteoporotic fracture and inflammatory cytokines. Methods: A total of 140 patients with spinal osteoporotic fracture were selected and randomly divided into a treatment group and a control group (n=70). The control group was treated by central corpectomy, and the control group was treated by anterior decompression. Results: The rate of excellent and good outcomes in the treatment group was 94.3%, and that of the control group was 78.6%, which differed significantly (P<0.05). Cobb angle and cord occupancy in the spinal canal of both groups significantly decreased (P<0.05), while height ratio of the injured vertebral body significantly increased (P<0.05). Meanwhile, there were statistically significant inter-group differences (P<0.05). During the three-month follow-up period, the treatment group was significantly less prone to complications such as superficial infection, spinal instability and screw breakage compared with the control group (P<0.05). The postoperative serum MMP-3 and IL-6 levels of both groups significantly decreased compared with those before surgeries (P<0.05), with statistically significant inter-group differences (P<0.05). Conclusion: Compared with central corpectomy, anterior decompression exerted better effects on spinal osteoporotic fracture by improving the prognosis and stabilizing the spine safely, which may be associated with the effectively reduced serum MMP-3 and IL-6 levels.

    Introduction. Hip fractures are common injuries in the older persons, with significant associated morbidity and mortality. The Irish Hip Fracture Database (IHFD) was implemented to monitor standards of care against international standards. Methods. The IHFD is a clinically led web-based audit. We summarize the data collected on hip fractures from April 2012 to March 2013 from 8 centres. Results. There were 843 patients with the majority being (70%) female. The 80–89-year age group accounted for the majority of fractures (44%). Most (71%) sustained a fall at home. Intertrochanteric fractures (40%) were most common. Only 28% were admitted to an orthopaedic ward within 4 hours. The majority (97%) underwent surgery with 44% having surgery within 36 hours. Medical optimization (35%) and lack of theatre space (26%) accounted for most of the surgical delay. While 29% were discharged home, 33% were discharged to a nursing home or other long-stay facilities. There was a 4% in-hospital mortality rate. Conclusions. Several key areas in both the database and aspects of patient care needing improvement have been highlighted. The implementation of similar databases has led to improved hip fracture care in other countries and we believe this can be replicated in Ireland. PMID:25548713

    Aim: To assess similarities and differences in patient-related characteristics before and after surgery for painful disabling hip osteoarthritis among elderly subgroups with and without a trauma history. Method: First, a cohort of 1000 hospitalized patients were assessed for trends in: perceived duration of the condition, pain intensity, functional performance ability, walking distance, body mass, and comorbidity characteristics among other factors. Then, the most salient of these patient-related characteristics were compared between 42 cases of hip osteoarthritis without a trauma history and 42 cases with a trauma history matched for age and gender, using medical records and standard data recording and analysis procedures. Results: Hip osteoarthritis cases with a prior hip fracture history had a longer duration of disability, and were more impaired functionally before surgery (p < 0.05) than those with no such history. They also had lower leg muscle strength and used more assistive devices. Conclusion: Patients undergoing hip replacement surgery for painful hip osteoarthritis who have a hip fracture history are likely to be more impaired and disabled than those with no such history.

    Increasing number of older patients are admitted to hospital with hip fractures. This review evaluates the common medical problems that arise as a consequence of having a hip fracture. Older patients with fractures commonly have co-morbidities that require evaluation prior to and after surgery. Joint acute orthopaedic-geriatric units have been established to provide comprehensive orthopaedic and medical care with some studies showing a reduction in postoperative complications and mortality. Recommendations surrounding the care of the older orthopaedic patient include early surgical fixation, the use of prophylactic antibiotics and thromboembolic prophylaxis, good perioperative pain control to improve ambulation, delirium detection and management to decrease the risk complications, such as institutionalisation, the avoidance of malnutrition, urinary tract management, osteoporosis management and the promotion of early mobilisation to improve functional recovery. Physicians are well placed to manage these patients with orthopaedic surgeons during the perioperative period. Sufficient evidence exists for most recommendations for fracture patients, but further research is needed in most areas. PMID:20049603

    Objectives To assess the magnitude and the burden of hip fracture on the health care system, including time trends in hip fracture rates, in-hospital death rates, length of hospital stay (LHS) and discharge destination. Design A retrospective study of discharge abstracts. Setting The Province of Ontario. Patients All patients (n = 93 660) over the age of 50 years and with a diagnosis of hip fracture discharged from hospital between 1981 and 1992 (excluding transfers). Main Outcome Measures Age-sex standardized hip fracture rates per 1000 population, in-hospital death rates and age-adjusted mean LHS. Results The overall hip fracture rate was 3.3 per 1000 persons (1.7 per 1000 men and 4.6 per 1000 women). There was no change in rates between 1981 and 1992 (p = 0.089), but there have been increases in the numbers of hip fractures. There was no change in the in-hospital death rate over time (p = 0.78). The age-adjusted mean LHS in 1981 was 28.6 days compared with 22.2 days in 1992. The numbers of hip fractures will increase from 8490 in 1990 to 16 963 in 2010. Conclusions Despite stable age-adjusted rates of hip fractures, the doubling of the number of hip fractures by the year 2010 due to an aging population will become an increasing burden on the health care system.

    Vertebral augmentation procedures are widely used to treat osteoporotic vertebral compression fractures (VCFs). We report our initial experience with radiofrequency-targeted vertebral augmentation (RF-TVA) in 20 patients aged 50 to 90 years with single-level, symptomatic osteoporotic VCF between T10 and L5, back pain severity > 4 on a 0 to 10 scale, Oswestry Disability Index ≥ 21%, 20% to 90% vertebral height loss compared to adjacent vertebral body, and fracture age < 6 months. After treatment, patients were followed through hospital discharge and returned for visits after 1 week, 1 month, and 3 months. Back pain severity improved 66% (P < 0.001), from 7.9 (95% CI: 7.1 to 8.6) at pretreatment to 2.7 (95% CI: 1.5 to 4.0) at 3 months. Back function improved 46% (P < 0.001), from 74 (95% CI: 69% to 79%) at pretreatment to 40 (95% CI: 33% to 47%) at 3 months. The percentage of patients regularly consuming pain medication was 70% at pretreatment and only 21% at 3 months. No adverse events related to the device or procedure were reported. RF-TVA reduces back pain severity, improves back function, and reduces pain medication requirements with no observed complications in patients with osteoporotic VCF. PMID:24228187

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of denosumab (Amgen Inc., UK) to submit evidence for the clinical and cost effectiveness of denosumab for the prevention of fragility fractures in post-menopausal women, as part of the Institute's single technology appraisal (STA) process. The University of Aberdeen Health Technology Assessment Group were commissioned to act as the Evidence Review Group (ERG); the role of the ERG being to appraise the manufacturer's submission and to produce an independent report. This article provides a description of the company submission, the ERG review and NICE's subsequent decisions. The manufacturer considered that denosumab would be appropriate for patients unable to take, comply with or tolerate oral bisphosphonates. Comparator treatments selected for the submission were, therefore, 'no treatment', raloxifene, strontium ranelate, intravenous zoledronic acid, intravenous ibandronate and teriparatide. The main effectiveness evidence for denosumab was derived from a large randomized controlled trial comparing denosumab with placebo. Given by subcutaneous injection at 6-monthly intervals for 3 years, denosumab reduced the incidence of hip fracture by 40%, and reduced the incidence of clinical vertebral fracture by 69%. An indirect treatment comparison was used to derive adjusted relative risk (RR) estimates for different types of fracture for each comparator versus placebo. The RRs (95% CI) applied for denosumab were 0.316 (0.208, 0.478) for clinical vertebral fracture, 0.605 (0.373, 0.983) for hip fracture and 0.842 (0.638, 1.110) for wrist fracture. Despite a number of concerns surrounding the methodology of the indirect comparison, the ERG was satisfied with the robustness of the effect estimates. The RR estimates were applied in a good-quality Markov model that took account of drug costs, administration and monitoring costs, costs associated with fractures, and long-term nursing home

    Fourth generation composite femurs (4GCFs, models #3406 and #3403) simulate femurs of males <80 years with good bone quality. Since most hip fractures occur in old women with fragile bones, concern is raised regarding the use of standard 4GCFs in biomechanical experiments. In this study the stability of hip fracture fixations in 4GCFs was compared to human cadaver femurs (HCFs) selected to represent patients with hip fractures. Ten 4GCFs (Sawbones, Pacific Research Laboratories, Inc., Vashon, WA, USA) were compared to 24 HCFs from seven females and five males >60 years. Proximal femur anthropometric measurements were noted. Strain gauge rosettes were attached and femurs were mounted in a hip simulator applying a combined subject-specific axial load and torque. Baseline measurements of resistance to deformation were recorded. Standardized femoral neck fractures were surgically stabilized before the constructs were subjected to 20,000 load-cycles. An optical motion tracking system measured relative movements. Median (95% CI) head fragment migration was 0.8mm (0.4 to 1.1) in the 4GCF group versus 2.2mm (1.5 to 4.6) in the cadaver group (p=0.001). This difference in fracture stability could not be explained by observed differences in femoral anthropometry or potential overloading of 4GCFs. 4GCFs failed with fracture-patterns different from those observed in cadavers. To conclude, standard 4GCFs provide unrealistically stable bone-implant constructs and fail with fractures not observed in cadavers. Until a validated osteopenic or osteoporotic composite femur model is provided, standard 4GCFs should only be used when representing the biomechanical properties of young healthy femurs.

    Abstract Bisphosphonates have been commonly used for the treatment of osteoporosis. However, there have been recent case reports of atypical fractures citing their long-term use, which inhibits the turnover of bone components. A 64-year-old woman visited the outpatient clinic with pain in her right thigh and ambulation difficulty. We found fractures at both pedicles of L4 vertebra. subtrochanteric region of right femur, and left femoral shaft upon a radiologic examination. She had taken intravenous ibandronic sodium for osteoporosis over 3 years. We changed the bishophonates to a parathyroid hormone because it was suspected that the multiple fractures were caused by the medication. Further, rehabilitation, including progressive weight bearing, was started. After 3 months of the conservative treatment, she was able to walk independently. In conclusion, it is necessary to evaluate the possibility of atypical fractures in osteoporotic patients when they complain of lower extremity pain and to consider alternative treatments instead of bisphosphonates.

    In osteoporotic hip fractures, fracture collapse is deliberately allowed by commonly used implants to improve dynamic contact and healing. The muscle lever arm is, however, compromised by shortening. We evaluated a cohort of 361 patients with AO/OTA 31.A1 or 31.A2 intertrochanteric fracture treated by the dynamic hip screw (DHS) who had a minimal follow-up of 3 months and an average follow-up of 14.6 months and long term survival data. The amount of fracture collapse and shortening due to sliding of the DHS was determined at the latest follow-up and graded as minimal (<1 cm), moderate (1-2 cm), or severe (>2 cm). With increased severity of collapse, more patients were unable to maintain their premorbid walking function (minimal collapse = 34.2%, moderate = 33.3%, severe = 62.8%, and p = 0.028). Based on ordinal regression of risk factors, increased fracture collapse was significantly and independently related to increasing age (p = 0.037), female sex (p = 0.024), A2 fracture class (p = 0.010), increased operative duration (p = 0.011), poor reduction quality (p = 0.000), and suboptimal tip-apex distance of >25 mm (p = 0.050). Patients who had better outcome in terms of walking function were independently predicted by younger age (p = 0.036), higher MMSE marks (p = 0.000), higher MBI marks (p = 0.010), better premorbid walking status (p = 0.000), less fracture collapse (p = 0.011), and optimal lag screw position in centre-centre or centre-inferior position (p = 0.020). According to Kaplan-Meier analysis, fracture collapse had no association with mortality from 2.4 to 7.6 years after surgery. In conclusion, increased fracture collapse after fixation of geriatric intertrochanteric fractures adversely affected walking but not survival. PMID:26955637

    Fat embolism was assessed at necropsy and correlated with clinical findings in the patients who died among 854 with fractured hips admitted to hospital between 1967 and August 1971. Sixteen cases of clinical importance were found, eight of which were judged to have been fatal or to have seriously contributed to death. Frequencies were as follows: 2.4 to 3.3% among 424 patients with subcapital fractures; 0.7 to 0.8% in the 405 with trochanteric fractures; 4.1 to 7% among subjects treated without operation, representing 30% of those who died within seven days; and 0.9 to 1.1% among patients treated by pinning, nailing, or nail-plating. The higher frequency in the conservatively treated group is probably related to selection of poor-risk subjects. Fat embolism was found in 6.8 to 8.0% of those with subcapital fractures treated by primary Thompson's arthroplasty which utilizes acrylic cement, and in none of those given Moore's prostheses for which cement is not used. Study of a larger group after Moore's prosthesis is required to establish its lack of special risk. Fat embolism accounted for all the deaths within seven days of Thompson's arthroplasty and for most within 14 days; it was clearly related to surgery in some cases.A possible explanation of the hazard of Thompson's arthroplasty is that fat globule entry is enhanced by a rise of intramedullary pressure due to proximal occlusion of the reamed marrow cavity. A controlled trial of the effect of venting the marrow cavity on the frequency of fat embolism is warranted. It is possible that the acrylic monomer may also contribute to venous entry of medullary fat. The higher-age group of those with subcapital fractures and associated chronic cardiac and pulmonary disease might make them more susceptible to fat embolization than those in whom arthroplasty is also carried out for chronic hip disease.

Sixteen cases of clinical importance were found, eight of which were judged to have been fatal or to have seriously contributed to death. Frequencies were as follows: 2·4 to 3·3% among 424 patients with subcapital fractures; 0·7 to 0·8% in the 405 with trochanteric fractures; 4·1 to 7% among subjects treated without operation, representing 30% of those who died within seven days; and 0·9 to 1·1% among patients treated by pinning, nailing, or nail-plating.

It is possible that the acrylic monomer may also contribute to venous entry of medullary fat. The higher-age group of those with subcapital fractures and associated chronic cardiac and pulmonary disease might make them more susceptible to fat embolization than those in whom arthroplasty is also carried out for chronic hip disease.

    This study investigated the effect of endplate deformity after an osteoporotic vertebral fracture in increasing the risk for adjacent vertebral fractures. Eight human lower thoracic or thoracolumbar specimens, each consisting of five vertebrae were used. To selectively fracture one of the endplates of the middle VB of each specimen a void was created under the target endplate and the specimen was flexed and compressed until failure. The fractured vertebra was subjected to spinal extension under 150 N preload that restored the anterior wall height and vertebral kyphosis, while the fractured endplate remained significantly depressed. The VB was filled with cement to stabilize the fracture, after complete evacuation of its trabecular content to ensure similar cement distribution under both the endplates. Specimens were tested in flexion-extension under 400 N preload while pressure in the discs and strain at the anterior wall of the adjacent vertebrae were recorded. Disc pressure in the intact specimens increased during flexion by 26 +/- 14%. After cementation, disc pressure increased during flexion by 15 +/- 11% in the discs with un-fractured endplates, while decreased by 19 +/- 26.7% in the discs with the fractured endplates. During flexion, the compressive strain at the anterior wall of the vertebra next to the fractured endplate increased by 94 +/- 23% compared to intact status (p < 0.05), while it did not significantly change at the vertebra next to the un-fractured endplate (18.2 +/- 7.1%, p > 0.05). Subsequent flexion with compression to failure resulted in adjacent fracture close to the fractured endplate in six specimens and in a non-adjacent fracture in one specimen, while one specimen had no adjacent fractures. Depression of the fractured endplate alters the pressure profile of the damaged disc resulting in increased compressive loading of the anterior wall of adjacent vertebra that predisposes it to wedge fracture. This data suggests that correction of

    Xiatianwu tablet is based on the theory of traditional Chinese medicine (TCM), combined with modern TCM pharmacology and selected 33 famous traditional Chinese crude drugs to compose. Its recipe helps cure rheumatism, relax tendons, promote blood circulation to relieve pain, et al. Although Xiatianwu tablets are widely applied to clinical remedy such as rheumatic arthritis, lumbar disc hernia, osteoarthritis and so on, there is no report about its application in fracture. This article is to observe the efficacy of compound Xiatianwu tablets in elderly patients with osteoporotic distal radius fractures and its impact on the wrist function and complications. 180 elderly patients with osteoporotic distal radius fractures, from January 2011 to June 2014, were divided into observation group and control group by the method of random number table, each group had 90 cases. The control group were gave Caltrate D after manipulative reduction and plaster immobilization, observation group were treated with compound Xiatianwu tablets in the basis of the control group. Efficacy, wrist function and complication rates were observed in two groups after treatment. The excellent and good rate was 95.56% in observation group better than 77.78% in control group, the difference was statistically significant (χ2 = 4.712, P < 0.05). The complication rate in observation group was significantly lower compared with the control group (P < 0.05). This study shows that compound Xiatianwu tablets can improve the efficacy in elderly patients with osteoporotic distal radius fractures, reduce the incidence of complications and relieve the pain of patients which plays a significant role in improving the quality of life.

    Background Asian-specific prediction models for estimating individual risk of osteoporotic fractures are rare. We developed a Korean fracture risk prediction model using clinical risk factors and assessed validity of the final model. Methods A total of 718,306 Korean men and women aged 50–90 years were followed for 7 years in a national system-based cohort study. In total, 50% of the subjects were assigned randomly to the development dataset and 50% were assigned to the validation dataset. Clinical risk factors for osteoporotic fracture were assessed at the biennial health check. Data on osteoporotic fractures during the follow-up period were identified by ICD-10 codes and the nationwide database of the National Health Insurance Service (NHIS). Results During the follow-up period, 19,840 osteoporotic fractures were reported (4,889 in men and 14,951 in women) in the development dataset. The assessment tool called the Korean Fracture Risk Score (KFRS) is comprised of a set of nine variables, including age, body mass index, recent fragility fracture, current smoking, high alcohol intake, lack of regular exercise, recent use of oral glucocorticoid, rheumatoid arthritis, and other causes of secondary osteoporosis. The KFRS predicted osteoporotic fractures over the 7 years. This score was validated using an independent dataset. A close relationship with overall fracture rate was observed when we compared the mean predicted scores after applying the KFRS with the observed risks after 7 years within each 10th of predicted risk. Conclusion We developed a Korean specific prediction model for osteoporotic fractures. The KFRS was able to predict risk of fracture in the primary population without bone mineral density testing and is therefore suitable for use in both clinical setting and self-assessment.

    Objective Bone cement augmentation procedures such as percutaneous vertebroplasty and balloon kyphoplasty have been shown to be effective treatment for acute or subacute osteoporotic vertebral compression fractures. The purpose of this study was to determine the efficacy of bone cement augmentation procedures for long standing osteoporotic vertebral compression fracture with late vertebral collapse and persistent back pain. Methods Among 278 single level osteoporotic vertebral compression fractures that were treated by vertebral augmentation procedures at our institute, 18 consecutive patients were included in this study. Study inclusion was limited to initially, minimal compression fractures, but showing a poor prognosis due to late vertebral collapse, intravertebral vacuum clefts and continuous back pain despite conservative treatment for more than one year. The subjects included three men and 15 women. The mean age was 70.7 with a range from 64 to 85 years of age. After postural reduction for two days, bone cement augmentation procedures following intraoperative pressure reduction were performed. Imaging and clinical findings, including the level of the vertebra involved, vertebral height restoration, injected cement volume, local kyphosis, clinical outcome and complications were analyzed. Results The mean follow-up period after bone cement augmentation procedures was 14.3 months (range 12-27 months). The mean injected cement volume was 4.1 mL (range 2.4-5.9 mL). The unipedicular approach was possible in 15 patients. The mean pain score (visual analogue scale) prior to surgery was 7.1, which decreased to 3.1 at 7 days after the procedure. The pain relief was maintained at the final follow up. The kyphotic angle improved significantly from 21.2 ± 4.9° before surgery to 10.4 ± 3.8° after surgery. The fraction of vertebral height increased from 30% to 60% after bone cement augmentation, and the restored vertebral height was maintained at the final follow up

    Background Recently, several consensus definitions for sarcopenia have been developed. Objective To evaluate the associations and discriminative ability of definitions of sarcopenia against clinical outcomes. Design Osteoporotic Fractures in Men study Setting Six clinical centers Participants 5,934 community-dwelling men aged ≥65 yrs Measurements Sarcopenia definitions evaluated were: International Working Group (IWG), European Working Group for Sarcopenia in Older Persons (EWGSOP), Foundation for the NIH (FNIH) Sarcopenia, Baumgartner, and Newman. Recurrent falls were defined as ≥2 self-reported falls in the year after baseline (N=694, 11.9%). Incident hip fractures (N=207, 3.5 %) and deaths (N=2003, 34.1%) were confirmed by central review of medical records over 9.8 years. Self-reported functional limitations were assessed at baseline and again 4.6 years later. Logistic regression or proportional hazards models estimated associations between sarcopenia and falls, hip fractures or death. The discriminative ability of the sarcopenia definitions (compared to referent models) for these outcomes was evaluated with areas under the receiver operator curve (AUCs) or C-statistics. Referent models included age alone for falls, function limitations and mortality, and age and BMD for hip fractures. Results The association between sarcopenia by the various definitions and risk of falls, functional limitations, and hip fractures was variable; all definitions were associated with increased mortality risk. However, none of the definitions materially changed discrimination based on AUC and C-statistic when compared to referent models (change ≤1% in all models). Conclusions Sarcopenia definitions as currently constructed did not consistently improve prediction of clinical outcomes in relatively healthy older men. PMID:26502831

    Background Pedicle screw instrumentation for treating spinal disorder is becoming increasingly widespread. Many studies have advocated its use to facilitate rigid fixation for spine; however, adjacent segmental disease is a known complication. Instrumented fusion for osteoporotic spines remains a significant challenge for spine surgeons. Prophylactic vertebroplasty for adjacent vertebra has been reported to reduce the complications of junctional compression fractures but has raised a new problem of vertebral subluxation. This case report is a rare and an extreme example with many surgical complications caused by repeated instrumented fusion for osteoporotic spine in a single patient. This patient had various complications including adjacent segmental disease, vertebral subluxation, and junctional fractures on radiographs and magnetic resonance images. Case presentation An 81-year-old Taiwanese woman underwent decompression and instrumented fusion of L4-L5 in Taiwan 10 years ago. Due to degenerative spinal stenosis of L3-L4 and L2-L3, she had decompression with instrumented fusion from L5 to L1 at the previous hospital. However, catastrophic vertebral subluxations with severe neurologic compromise occurred, and she underwent salvage surgeries twice with prolonged instrumented fusion from L5 to T2. The surgeries did not resolve her problems of spinal instability and neurologic complications. Eventually, the patient remained with a Frankel Grade C spinal cord injury. Conclusion Adjacent segmental disease, junctional fracture, and vertebral subluxation are familiar complications following instrumented spinal fusion surgeries for osteoporotic spines. Neurologic injuries following long instrumentation are often serious and difficult to address with surgery alone. Conservative treatments should always be contemplated as an alternative method for patients with poor bone stock. PMID:27555778

  5. Current Challenges in Pain Management in Hip Fracture Patients.

    PubMed

    Sanzone, Anthony G

    2016-05-01

    The high incidence of hip fracture, together with considerable associated morbidity, mortality, and cost of care, makes this injury a major clinical challenge. Of particular importance is the pain associated with hip fracture, which can have potentially severe consequences and may lead to delayed recovery. The prevailing opioid-dependent model of analgesia, however, presents multiple drawbacks and risks that can compromise outcomes in the hip fracture population. The pain management process has essential preoperative, intraoperative, and postoperative components, yet data on the comparative effectiveness of different pain management interventions in patients undergoing surgery for hip fracture are not clear cut. A Cochrane database review that included 83 different pain management studies indicated that there are not enough well-designed studies to show unequivocally which pain management approaches work well after hip fracture surgery. Yet a growing body of data on certain interventions, such as nerve blocks and multimodal analgesia, supports consideration of these options. PMID:27101319

    INTRODUCTION Hip fractures are common in the elderly. Published studies have not shown significant differences in mortality rates between hip fracture patients who were managed nonoperatively and operatively. This retrospective study looked at 340 patients with hip fractures who were admitted to a local hospital over one year, and compared the long-term mortality between those treated operatively and nonoperatively. METHODS All patients with hip fractures were identified retrospectively from the hospital’s hip registry. Mortality data was collected through nationwide electronic medical records and telephone interviews. RESULTS Overall mortality rates at one (14.4%) and two years (24.4%) were comparable to those of other studies. Hip fracture patients who were treated nonoperatively had a higher risk of mortality at both one (29.8%) and two years (45.6%) after fracture (p < 0.05). Their risk of mortality was four times higher at one year and three times higher at two years after fracture than the operative group. Patients with a higher American Society of Anesthesiologists (ASA) grade did not show an increased risk in mortality compared to patients with a lower ASA grade at both one year (p = 0.072) and two years (p = 0.360) after fracture. CONCLUSION Elderly patients with hip fractures should be managed surgically and counselled regarding the increased risk of mortality if treated nonoperatively. PMID:27075376

    Osteoporotic vertebral fractures are uncommon in young adults and usually indicate an underlying disease. Systemic mastocytosis is a myeloproliferative neoplasm, which can be associated with osteoporosis. A previously healthy 30-year-old man presented with an L4 burst fracture after lifting a heavy object. He was operated with laminectomy and posterior lumbar instrumentation. During surgery, abnormally soft bone was noted. Postoperatively, osteoporosis was confirmed with measurement of bone mineral density. Further investigation revealed elevated serum tryptase levels while bone marrow biopsy findings showed systemic mastocytosis. He was also tested positive for D816V KIT mutation. Treatment with biphosphonates and interferon was initiated. No extraskeletal involvement was noted up to the last checkup, 18 months after the first presentation. Abrupt vertebral fractures in apparently healthy young individuals should raise the suspicion of an underlying pathology. Prompt identification and treatment of systemic mastocytosis is crucial in order to avoid unexpected sequelae. PMID:27141048

    2012-01-01

    Background The WHO has recently published the FRAX® tool to determine the absolute risk of osteoporotic fracture at 10 years. This tool has not yet been validated in Spain. Methods/design A prospective observational study was undertaken in women in the FRIDEX cohort (Barcelona) not receiving bone active drugs at baseline. Baseline measurements: known risk factors including those of FRAX® and a DXA. Follow up data on self-reported incident major fractures (hip, spine, humerus and wrist) and verified against patient records. The calculation of absolute risk of major fracture and hip fracture was by FRAX® website. This work follows the guidelines of the STROBE initiative for cohort studies. The discriminative capacity of FRAX® was analyzed by the Area Under Curve (AUC), Receiver Operating Characteristics (ROC) and the Hosmer-Lemeshow goodness-of-fit test. The predictive capacity was determined using the ratio of observed fractures/expected fractures by FRAX® (ObsFx/ExpFx). Results The study subjects were 770 women from 40 to 90 years of age in the FRIDEX cohort. The mean age was 56.8 ± 8 years. The fractures were determined by structured telephone questionnaire and subsequent testing in medical records at 10 years. Sixty-five (8.4%) women presented major fractures (17 hip fractures). Women with fractures were older, had more previous fractures, more cases of rheumatoid arthritis and also more osteoporosis on the baseline DXA. The AUC ROC of FRAX® for major fracture without bone mineral density (BMD) was 0.693 (CI 95%; 0.622-0.763), with T-score of femoral neck (FN) 0.716 (CI 95%; 0.646-0.786), being 0.888 (CI 95%; 0.824-0.952) and 0.849 (CI 95%; 0.737-0.962), respectively for hip fracture. In the model with BMD alone was 0.661 (CI 95%; 0.583-0.739) and 0.779 (CI 95%; 0.631-0.929). In the model with age alone was 0.668 (CI 95%; 0.603-0.733) and 0.882 (CI 95%; 0.832-0.936). In both cases there are not significant differences against FRAX® model. The overall

    Introduction Osteoporotic vertebral fractures relate to poorer quality of life and higher long-term mortality. In a resource-poor setup, conservative management assumes great importance as primary means of treatment. We assess the clinico-pathological epidemiology of osteoporotic vertebral fractures and prospectively evaluate the effectiveness of conservative management in their treatment. Materials & Methods    Thirty consecutive patients, diagnosed with osteoporotic vertebral fracture, underwent the predetermined protocol of conservative treatment (bed rest, titrated analgesia, antiosteoporosis pharmacotherapy, bracing, and supervised physical therapy) after assessment of basic demographic data and clinical examination. They were evaluated every three months for nine months, using visual analog scale (VAS) for backpain, Oswestry Disability Index (ODI), and radiological and hematological parameters. Results  The mean age of the patients was 66.9 +/-7.6 years and the female: male ratio was 14:1. All (100%) women were postmenopausal and the mean time since menopause was 16.75 +/- 8.12 years. The presenting complaints were backpain (100%) and deformity (53.33%). Neurodeficit was noted in one (3.33%) patient. Higher age was correlated to greater vertebral collapse (p=0.001) and higher kyphotic angle (p=0.002). At nine months after treatment, there was a significant decrease in the VAS score (p<0.0001) and the ODI score (p<0.0001), with the final VAS score improving by 49.25% and the ODI score improving by 47.23% from the baseline. There was progressive increase in vertebral collapse (p=0.0474) with no change in kyphotic or scoliotic angles. With treatment there was a consistent increase in serum calcium (p<0.0001), phosphorous (p<0.0001), and vitamin D3 (p<0.0001) levels, and decrease in parathyroid hormone levels (p<0.0001).

    Osteoporosis is a major health issue worldwide, with significant economic consequences and adverse impacts on the quality of life. Hip fractures are the most devastating complication of osteoporosis, are likely to increase exponentially with an increasingly aged population, are associated with high recurrence rate, and lead to significant morbidity and mortality. This review discusses the prevalence and impact of hip fractures, the assessment of fracture risk, fall prevention, and treatment of osteoporosis with emphasis on evidence for hip fracture reduction among the various agents currently available. The aim is to provide recommendations to optimize hip fracture prevention and treatment. Ample evidence exists in the literature of many other risk factors independent from bone mineral density that increase fracture risk. These clinical risk factors have been validated in large cohorts and are incorporated into clinical tools that are invaluable in treatment decisions. In addition, strategies to prevent or reduce falls are integral to comprehensive osteoporosis management. Vitamin D combined with calcium has a role in primary prevention. Alendronate, residronate, strontium and zoledronic acid have proven efficacy in primary and secondary hip fracture prevention. An aggressive approach to investigate, assess and manage an individual's fracture risk and fall risk is paramount to reduce the high morbidity and mortality associated with hip fractures. The choice of therapy should be determined by the patient's calculated fracture risk and efficacy of the potential treatment, including long term compliance associated with the agent of choice.

    In this observational, case-control study, 376 inpatients were evaluated in order to determine the association of risk factors (RF) and hip fracture; 151 patients had osteoporotic hip fracture (cases); the remaining were controls. Data were obtained from medical charts, and through a standardized questionnaire about RF. Mean age of the sample (+/- SD) was 80.6 +/- 8.1 years, without statistically significant difference between cases and controls; the female:male ratio was 3:1 in both groups. Fractured women were older than men (82.5 +/- 8.1 vs. 79.7 +/- 7.2 years, respectively; p < 0.01). Physical activity, intake of alcohol and tobacco, and sun exposure were low in all patients. Falls among cases happened predominantly at home (p < 0.001). Among female cases, time spent in household duties was a RF (p = 0.007), which was absent in males. In multivariate analysis, the following RF were significantly more frequent: Cognitive impairment (p = 0.001), and previous falls (p < 0.0001); whereas the following protective factors were significantly different from controls: Calcium intake during youth (p < 0.0001), current calcium intake (p < 0.0001), and mechanical aid for walking (p < 0.0001). Evaluation of RF and protective factors may contribute to diminish the probability of hip fracture, through a modification of personal habits, and measures to prevent falls among elderly adults. Present information can help to develop local and national population-based strategies to diminish the burden of hip fractures for the health system. PMID:18051223

    INTRODUCTION: Osteoporotic fractures are common during osteoporotic states. Piper sarmentosum extract is known to possess antioxidant and anti-inflammatory properties. OBJECTIVES: To observe the radiological changes in fracture calluses following administration of a Piper sarmentosum extract during an estrogen-deficient state. METHODS: A total of 24 female Sprague-Dawley rats (200-250 g) were randomly divided into 4 groups: (i) the sham-operated group; (ii) the ovariectomized-control group; (iii) the ovariectomized + estrogen-replacement therapy (ovariectomized-control + estrogen replacement therapy) group, which was supplemented with estrogen (100 µg/kg/day); and (iv) the ovariectomized + Piper sarmentosum (ovariectomized + Piper sarmentosum) group, which was supplemented with a water-based Piper sarmentosum extract (125 mg/kg). Six weeks after an ovariectomy, the right femora were fractured at the mid-diaphysis, and a K-wire was inserted. Each group of rats received their respective treatment for 6 weeks. Following sacrifice, the right femora were subjected to radiological assessment. RESULTS: The mean axial callus volume was significantly higher in the ovariectomized-control group (68.2±11.74 mm3) than in the sham-operated, estrogen-replacement-therapy and Piper sarmentosum groups (20.4±4.05, 22.4±4.14 and 17.5±3.68 mm3, respectively). The median callus scores for the sham-operated, estrogen-replacement-therapy and Piper sarmentosum groups had median (range, minimum - maximum value) as 1.0 (0 - 2), 1.0 (1 - 2) and 1.0 (1 - 2), respectively, which were significantly lower than the ovariectomized-control group score of 2.0 (2 - 3). The median fracture scores for the sham-operated, estrogen-replacement-therapy and Piper sarmentosum groups were 3.0 (3 - 4), 3.0 (2 - 3) and 3.0 (2 - 3), respectively, which were significantly higher than the ovariectomized-control group score of 2.0 (1 - 2) (p<0.05).

    Eighty-seven osteoporotic vertebral fractures of 82 patients were treated with balloon kyphoplasty. Preoperative, postoperative and follow-up outcomes of functional impairment, pain scores and vertebral height restorations of the patients were recorded and evaluated statistically. Seventy-two of the patients were female (87.8%) and 10 (12.2%) were male. Mean age of all patients were 66.4 years. Preoperative mean Anterior Vertebral Body Height of 48.20±13.94 % and Middle Vertebral Body Height of 59.40±14.26 % were recorded as 79.91±9.50 % and 86.90±8.38 % respectively postoperatively and noted to be 73.26±8.59 % and 84.65±8.19 % at last controls respectively. The mean Oswestry Disability Index and Visual Analog Pain Scale also improved significantly. Local Kyphosis of all the patients were also evaluated and a significant improvement was noted postoperatively. The long term results of this study suggest that balloon kyphoplasty is an effective and safe treatment option in osteoporotic vertebral fractures and should be considered for functional improvement, pain relief and height restoration.

    Areal bone mineral density (BMD) by DXA, although an important index, does not accurately assess risk of fragility fracture. Another bone structural parameter, the orientation of type I collagen, is known to add to risk determination, independently of BMD. Accordingly, we investigated the Haversian systems of transiliac crest biopsies from non-osteoporotic women with low-trauma fractures, matched to healthy women without fracture by age and BMD. We employed circularly polarized light (CPL) microscopy because 1) each of the extinct and bright birefringent signals of CPL corresponds to a specific collagen arrangement; and 2) CPL can employ magnification suitable to provide data, of manageable size, from the whole cortical component of a section of biopsy. Under CPL, the coaxial layers of osteons, called lamellae, appear either birefringent extinct or bright. On a section transverse to the Haversian system, the extinct lamella comprises mainly collagen forming small angles, and the bright lamella comprises mainly collagen forming large angles, relative to the general orientation of the Haversian system. We performed semi-automatic morphometry for birefringent and structural parameters for which we computed intra- and inter-observer errors. The statistical analysis used a linear mixed model to compare fracturing and non-fracturing groups while addressing pairing of fracturing and non-fracturing subjects, and linear regression to assess differences between matched subjects. We found significant reduction in 1) lamellar width and area for extinct lamella and bright lamella; 2) percentage of extinct birefringence in osteons, and 3) single osteon area; in the fracturing group; and in lamellar width in the fracturing subject of all pairs. Our results evidence the need to investigate, in a larger sample of subjects, the distribution of collagen orientation as a parameter diagnostic of increased fracture risk. PMID:26514952

    Dislocation of the hip is a critical injury that results from high-energy trauma. This paper describes a case of posterior dislocation of the right hip in a 35-year-old woman with associated ipsilateral femoral head fracture. Initial treatment included reduction of the right hip through posterior approach and fixation of the femoral head fracture with three absorbable screws. After 15-month follow-up, a full range of motion has been achieved and there are no signs of avascular necrosis, hip instability, or limping. The authors describe their method of surgery.

    We aimed to evaluate the effects of intertrochanteric femoral fractures on mortality, morbidity, and cost of zoledronate treatment in elderly patients treated by osteosynthesis. Based on Evans classification, 114 patients with unstable intertrochanteric femoral fractures were treated with osteosynthesis. After the surgical treatment of intertrochanteric fractures, the treatment group (M/F, 24/32; mean age, 76.7 ± SD years) received zoledronate infusion, and the control group (M/F, 20/38; mean age, 80.2 ± SD years) received placebo. Postoperative control visits were performed at 6-week, 3-month, 6-month, and 12-month time points. Functional level of patients was evaluated by the modified Harris hip score and Merle d'Aubigné hip score. By 12 months, the mean HHS in treatment and control groups was 81.93 and 72.9, respectively. For time of death of the patients, mortality was found to be 57.1% (16/28) on the first 3 months and 92.9% (26/28) on the first six months. The mortality rate in the treatment and control groups was 14.3% (8/56) and 34.5% (20/58), respectively. The use of zoledronic acid after surgical treatment of intertrochanteric femoral fractures in osteoporotic elderly patients is a safe treatment modality which helps to reduce mortality, improves functional outcomes, and has less side effects with single dose use per year.

    The fracture of the proximal femur or hip fracture in the elderly usually happens after a fall and carries a high morbidity and mortality. One of the most common complications during hospitalization for hip fracture is the onset of delirium or acute confusional state that in elderly patients has a negative impact on the hospital stay, and prognosis, worsening functional ability, cognitive status and mortality. Also the development of delirium during hospitalization increases health care costs. Strategies to prevent and treat delirium during hospitalization for hip fracture have been less studied. In this context, this paper aims to conduct a review of the literature on strategies that exist in the prevention and treatment of delirium in elderly patients with hip fracture. PMID:23790577

    The aim of this study was to assess the influence of bone mineral density and hip geometry on the fragility fracture of femoral neck and trochanteric region. There were 95 menopausal females of age ≥ 50 years with fragility fracture of hip, including 55 cases of femoral neck fracture and 40 cases of trochanteric fracture. Another 63 non-fractured females with normal bone mineral density (BMD) were chosen as control. BMD, hip axis length, neck-shaft angle and structural parameters including cross surface area, cortical thickness and buckling ratio were detected and compared. Compared with control group, the patients with femoral neck fracture or trochanteric fractures had significantly lower BMD of femoral neck, as well as lower cross surface area and cortical thickness and higher buckling ratio in femoral neck and trochanteric region. There were no significant differences of BMD and structural parameters in the femoral neck fracture group and intertrochanteric fracture group. Hip axis length and neck-shaft angle were not significantly different among three groups. The significant changes of BMD and proximal femur geometry were present in the fragility fracture of femoral neck and trochanteric region. The different types of hip fractures cannot be explained by these changes. PMID:26773177

    This study aimed to investigate the clinical effect of percutaneous kyphoplasty and the precautions against adjacent vertebral refractures in the treatment of multiple osteoporotic vertebral compression fractures. 54 cases (128 vertebrae) with multiple osteoporotic vertebral compression fractures from July 2007 to December 2013 treated with percutaneous kyphoplasty were retrospectively reviewed. 36 cases of them suffered from bi-segment vertebral fractures, 16 cases with tri-segment vertebral fractures and 2 cases with quadri-segment vertebral fractures. The operative effect was evaluated by visual analogue scale (VAS) score and oswestry disability index (ODI) score. Then the reasons for adjacent vertebral refractures were analyzed and the precautions were proposed. 54 cases (128 vertebrae) were admitted with percutaneous kyphoplasty successfully. No pulmonary embolism, spinal cord injury and other serious complications were found. The follow-up took 3-33 months with the average of 12 months. There was significant difference of VAS scores and ODI scores between pre-operation and post-operation (P<0.05). Bone cement leakage occurred in 23 vertebrae, and the incidence rate was 18.0%. 8 cases sustained adjacent vertebral refractures including 3 cases in the contiguous vertebral bodies and 5 cases in the interval vertebral bodies, and the incidence rate was 14.8%. 5 cases gained fracture healing after additional percutaneous kyphoplasty procedures while the other 3 cases were healed basically after conservative treatment for three months. In conclusion, percutaneous kyphoplasty is safe and effective to treat multiple osteoporotic vertebral compression fractures. However, the risk of new adjacent vertebral fractures in the multiple osteoporotic vertebral compression fractures is higher than that in the single osteoporotic vertebral compression fracture. Timely and proper treatment can reduce refractures. PMID:26550284

    Summary Hip fracture incidence in the Canaries was studied in two 5-year periods (1989–1993 and 2008–2011). The incidence in 2007–2011 was 24 % higher than in 1989, but did not differ between 2007–2011 and 1993. These findings suggest a trend to stabilize the incidence of hip fracture. Introduction A dramatic increase in hip fractures between 1988 and 2002 was reported in Northern Spain. We performed the present study in Gran Canaria, the Canary Islands, to compare changes in the incidence of hip fracture between 1989–1993 and 2007–2011. Methods We recorded every osteoporotic hip fracture admitted to any hospital in Gran Canaria in the population 50 years of age or older. Results In 1989–1993, we collected 1175 hip fractures (72 % women; mean age 78.2±9.9 years), and the total incidence rate was 152.1 cases/100,000 population/year. In 2007–2011, we collected 2222 hip fracture cases (71 % women; mean age 79±9.8 years). The total incidence was 180.9/100,000/year. A Poisson model showed that the incidence of fractures increased by 7.1 % (95 % CI=3.1 %; 11.8 %) each year in 1989–1993, while there was no statistically significant variation (p=0.515) during the period 2007–2011. The incidence in 2007–2011 was 24 % higher than in 1989 (first year in the first period) but did not differ between 2007–2011 and 1993 (the last year of the first period). Incidence rates were 76.7 % (95 % CI=63.9 %; 90.5 %) higher in women than in men, but the female/male ratio remained unchanged. The age-adjusted incidence of hip fractures increased by 7.3 % each year from 1989 to 1993. The proportions of trochanter and cervical fractures were similar in the two time periods, but the mean hospital stay was reduced from 11 days in 1989–1993 to 7 days in 2007–2011. Conclusions These findings suggest a trend to stabilize the incidence of hip fracture in the Canary Islands due to a decrease in men, while in women, the incidence increased. PMID:25572042

    Osteoporosis is a progressive disease of the skeleton characterised by bone fragility due to a reduction in bone mass and possibly to alteration in bone architecture that lead to a propensity to fracture with minimum trauma. Most osteoporotic fractures occur at locations rich in trabecular or cancellous bone and usually related to post menopausal women. Recently, silymarin received attention due to its alternative beneficial effect on bone formation. It is a mixture of flavonoids with powerful antioxidant properties. This review focuses on the use of milk thistle or silymarin for the treatment of osteoporosis that may be related to fracture bone. Silymarin shows potent antioxidant herb that may modulate multiple genes in favour of helping to build bone and prevent bone loss. In the mouse fracture healing model, silymarin supplementation improved tibial healing with elevated BMD and serum levels of ALP and osteocalcin. Silymarin also demonstrated clear estrogenic antiosteoporotic effects in bone structure. Silymarin appears to play a crucial role to prevent bone loss and might regulate osteogenesis and may be beneficial for fracture healing. If silymarin is considered for the use of post menopausal women, it may be used for the treatment of osteoporosis. It would be of great benefit to postmenopausal women to develop an oestrogen antagonist that is as potent and efficacious as oestrogen in preventing bone loss without the major side effect associated with HRT.

    Delayed bone healing has been noted in osteoporosis patients and in the ovariectomized (OVX) rat model of estrogen-depletion osteopenia. Pulsed electromagnetic field (PEMF) devices are clinically approved as an adjunct to cervical fusion surgery in patients at high risk for non-fusion and for the treatment of fracture non-unions. These bone growth stimulating devices also accelerate the healing of fresh fracture repair in skeletally mature normal rats but have not been tested for efficacy to accelerate and/or enhance the delayed bone repair process in OVX rats. The current study tested the hypothesis that daily PEMF treatments would improve the fracture healing response in skeletally mature OVX rats. By 6 weeks of healing, PEMF treatments resulted in improved hard callus elastic modulus across fibula fractures normalizing the healing process in OVX rats with respect to this mechanical property. Radiographic evidence showed an improved hard callus bridging across fibula fractures in OVX rats treated with PEMF as compared to sham treatments. These findings provide a scientific rationale for investigating whether PEMF might improve bone-healing responses in at-risk osteoporotic patients. PMID:24764277

    We investigated the incidence, risk factors and outcome of acute renal dysfunction (ARD) in patients with a fractured neck of femur. 170 consecutive patients were prospectively included in the Scottish Hip Fracture Audit database and retrospectively analysed. Historically, lack of consensus definition has hindered accurate reporting of ARD. ARD was defined using the 'RIFLE' criteria. 27 patients (16%) developed ARD. Risk factors were male sex, vascular disease, hypertension, diabetes, chronic kidney disease and pre-morbid use of nephrotoxic medications (p<0.01). Inpatient, 30- and 120-day mortality was higher in the ARD group 19%, 22% and 41% respectively, versus 0%, 4% and 13% in the non-ARD group (p<0.01). Length of hospital stay was significantly longer in the ARD group. Pre- and post-operative complications were 12 and 5 times more frequent respectively in the ARD group (p<0.01). Awareness of risk factors and serial measurements of renal function allow early identification and focused monitoring of these patients. PMID:19729159

    Objective To investigate the value of lumbar bone mineral density (BMD) in fracture risk assessment (FRAX) tool. Methods One hundred and ten patients aged over 60 years were enrolled and divided into 2 groups as non-osteoporotic vertebral fracture (OVF) and OVF groups. The 10-year-risk of major osteoporotic vertebral fracture of each group was calculated by FRAX tool with femoral and lumbar spine BMDs to compare the usefulness of lumbar spine BMD in prediction of OVF. The blood level of osteocalcin and C-terminal telopeptide (CTX) as markers of activities of osteoblast and osteoclast, respectively were analyzed using the institutional database. Results In the OVF group, the ratio of patients with previous fracture history or use of glucocorticoid was higher than those in non-OVF group (p=0.000 and 0.030, respectively). The levels of T-score of femur neck and lumbar spine in OVF group were significantly lower than those in non-OVF group (p=0.001 and 0.000, respectively). The risk of OVF in FRAX using femur BMD in non-OVF and OVF groups was 6.7±6.13 and 11.4±10.06, respectively (p=0.007). The risk of using lumbar BMD in the 2 groups was 6.9±8.91 and 15.1±15.08, respectively (p=0.002). The areas under the receiver operator characteristic curve in the FRAX risk with lumbar and femur neck BMD were 0.726 and 0.684, respectively. The comparison of osteocalcin and CTX was not significant (p=0.162 and 0.369, respectively). Conclusion In our study, the 10-year risk of major osteoporotic fracture in the OVF group of our study was lower than the recommended threshold of intervention for osteoporosis. Hence, a lower threshold for the treatment of osteoporosis may be set for the Korean population to prevent OVF. In the prediction of symptomatic OVF, FRAX tool using lumbar spine BMD may be more useful than that using femur neck BMD. PMID:26587188

    Failed treatment of an intertrochanteric fracture typically leads to profound functional disability and pain. Salvage treatment with hip arthroplasty may be considered. The aim of this study was to evaluate the results and complications of hip arthroplasty performed as a salvage procedure after the failed treatment of an intertrochanteric hip fracture. Twenty-one patients were treated in our hospital with hip arthroplasty for failed treatment of intertrochanteric hip fracture. There were sixteen women and five men with a mean age of 75.8 years (range 61-85 years). Fourteen patients had failure of a previous nail fixation procedure, five had failure of a plate fixation, one of hip screws fixation and one of Ender nail fixation. In 19 out of 21 patients we performed a total hip arthroplasty-14 cases used modular implants with long-stems and five cases used a standard straight stem. In 2 of 21 cases we used a bipolar hemiarthroplasty. A statistically significant improvement was found comparing pre and postoperative conditions (p < 0.05). Our experience confirms that total hip arthroplasty is a satisfactory salvage procedure after failed treatment of an intertrochanteric fracture in elderly patients with few serious orthopaedic complications and acceptable clinical outcomes.

    Slightly focused high-energy shockwave (HESW) therapy is characterized by a wide focal area, a large therapy zone, easy positioning and less pain during treatment. The objective of this study was to perform for the first time an in vivo test of the slightly focused HESWs for osteoporotic fractures. Bilateral proximal tibial osteotomies were made in 30 ovariectomized (OVX) Sprague-Dawley rats and secured with internal fixation. The osteotomy site in the left tibia was subsequently treated with slightly focused HESWs with the energy flux density of 0.26 mj/mm2, shock repetition frequency of 1 Hz and 2000 shocks (OVX + HESW group). The contralateral right tibia was not treated and served as the control (OVX group). Roentgenographic examination 2, 4, 6, and 8 weeks after osteotomy showed that HESW treatment accelerated tibia fracture healing in osteoporotic rats. Histological examination 2, 4, and 8 weeks after HESW treatment showed a greater inflammatory reaction in the OVX + HESW group, with more mature collagen and trabeculae than in the OVX group. Micro computer tomography (Micro-CT) scanning after 4 and 8 weeks showed that bone volume (BV), bone volume/tissue volume (BV/TV), mean trabecular thickness (Tb.Th), and mean trabecular number (Tb.N) were about 45.0% and 33.1%, 18.4% and 20.1%, 38.2% and 20.9%, 26.7% and 28.4%, respectively, higher in the treatment group than in the control group (P < 0.05); and the mean trabecular separation (Tb.Sp) was about 16.7% and 27.3% lower in the treatment group (P < 0.05). Four and eight weeks after HESW treatment, the maximum compressive callus endurance was about 72.3% and 25.5%, respectively, higher in the treatment group than in the control group (P < 0.05). These results show that slightly focused HESW therapy has a beneficial effect on osteoporotic tibial fracture healing. Slightly focused HESWs could increase callus endurance, induce bone formation, and improve trabecular bone microarchitecture and biomechanical

    Inferior dislocation is a rare type of hip dislocation, especially in adults. Few cases have been reported; most of them were isolated. This is the case of a traumatic adult hip dislocation after a road traffic accident. Reduction was made under general anaesthesia; a CT-Scan after the reduction showed a bifocal non-displaced hip fracture. In this article, we present a small review of the literature and we discuss the possible mechanism of hip dislocation. We found through our case study that this condition is not exclusive to children and CT-Scan is mandatory after the reduction of hip dislocation to eliminate any associated injury. To our knowledge, a bifocal hip fracture has not previously been documented, in the English language literature. PMID:27141043

    The incidence of hip fracture is expected to increase as the population ages. One in five persons dies in the first year after sustaining a hip fracture, and those who survive past one year may have significant functional limitation. Although surgery is the main treatment for hip fracture, family physicians play a key role as patients' medical consultants. Surgical repair is recommended for stable patients within 24 to 48 hours of hospitalization. Antibiotic prophylaxis is indicated to prevent infection after surgery. Thromboprophylaxis has become the standard of care for management of hip fracture. Effective agents include unfractionated heparin, low-molecular-weight heparin, fondaparinux, and warfarin. Optimal pain control, usually with narcotic analgesics, is essential to ensure patient comfort and to facilitate rehabilitation. Rehabilitation after hip fracture surgery ideally should start on the first postoperative day with progression to ambulation as tolerated. Indwelling urinary catheters should be removed within 24 hours of surgery. Prevention, early recognition, and treatment of contributing factors for delirium also are crucial. Interventions to help prevent future falls, exercise and balance training in ambulatory patients, and the treatment of osteoporosis are important strategies for the secondary prevention of hip fracture.

    Background Osteoporosis treatment following hip fracture is well known to not enough. We previously performed intervention study for orthopaedic surgeon's education and reported twofold increase in osteoporosis detection and treatment rate observed between 2005 and 2007. This follow-up observational study was conducted to find out the rate in which a diagnostic workup and treatment for osteoporosis were done in patients with hip fracture. Methods Medical records and radiographs in patients who were older than 50 years and diagnosed as having femoral neck or intertrochanteric fractures at 8 hospitals in Jeju island, South Korea from 2008 to 2011 were reviewed. The numbers of patients who were studied with bone densitometry and who were treated for osteoporosis after the diagnosis of hip fracture were analyzed. Results Nine hundred forty five hip fractures (201 in 2008, 257 in 2009, 265 in 2010, and 304 in 2011) occurred in 191 men and 754 women during the study periods. The mean age of the patients was 79.7 years. The mean rate of osteoporosis detection using dual energy X-ray absorptiometry was 36.4% (344/945 hips) (ranged from 24.2% in 2009 to 40.5% in 2011). The mean initiation rate of osteoporosis treatment was 23.1% (218/945 hips) (ranged from 20% in 2009 to 29% in 2008). Conclusions Detection and treatment rate of osteoporosis following hip fracture during follow-up periods was still not enough. Additional intervention studies are required to further improvement of osteoporosis treatment rates after hip fracture. PMID:25489575

    Background To assess the cost-effectiveness of drug therapy to prevent osteoporotic fractures in postmenopausal women with osteopenia in Korea. Methods A Markov cohort simulation was conducted for lifetime with a hypothetical cohort of postmenopausal women with osteopenia and without prior fractures. They were assumed to receive calcium/vitamin D supplements only or drug therapy (i.e., raloxifene or risedronate) along with calcium/vitamin D for 5 years. The Markov model includes fracture-specific and non-fracture specific health states (i.e. breast cancer and venous thromboembolism), and all-cause death. Published literature was used to determine the model parameters. Local data were used to estimate the baseline incidence rates of fracture in those with osteopenia and the costs associated with each health state. Results From a societal perspective, the estimated incremental cost-effectiveness ratios (ICERs) for the base cases that had T-scores between -2.0 and -2.4 and began drug therapy at the age of 55, 60, or 65 years were $16,472, $6,741, and -$13,982 per quality-adjusted life year (QALY) gained, respectively. Sensitivity analyses for medication compliance, risk of death following vertebral fracture, and relaxing definition of osteopenia resulted in ICERs reached to $24,227 per QALY gained. Conclusions ICERs for the base case and sensitivity analyses remained within the World Health Organization's willingness-to-pay threshold, which is less than per-capita gross domestic product in Korea (about $25,700). Thus, we conclude that drug therapy for osteopenia would be a cost-effective intervention, and we recommend that the Korean National Health Insurance expand its coverage to include drug therapy for osteopenia.

    Accurate recording of adverse events post hip fracture surgery is vital for planning and allocating resources. The purpose of this study was to compare adverse events recorded prospectively at point of care with adverse recorded by the Hospital In-Patient Enquiry (HIPE) System. The study examined a two month period from August to September 2011 at University Hospital Limerick. Out of a sample size of 39, there were 7 males (17.9%) and 32 females (82.1%) with an age range of between 53 and 98 years. The mean age was 80.5 years. 55 adverse events were recorded, in contrast to the HIPE record of 13 (23.6%) adverse events. The most common complications included constipation 10 (18.2%), anaemia 8 (14.5%), urinary retention 8 (14.50%), pneumonia 5 (9.1%) and delirium 5 (9.1%). Of the female cohort, 24 (68.8%) suffered an adverse event, while only 4 (57%) males suffered an adverse event. PMID:24579408

    Abstract Objective: Although the majority of available evidence suggests that vertebroplasty and kyphoplasty can relieve pain associated with vertebral compression fractures (VCFs) and improve function, some studies have suggested results are similar to those of placebo. The purpose of this meta-analysis was to compare the outcomes of vertebroplasty and kyphoplasty with conservative treatment in patients with osteoporotic VCFs. Methods: Medline, Cochrane, and Embase databases were searched until January 31, 2015 using the keywords: vertebroplasty, kyphoplasty, compression fracture, osteoporotic, and osteoporosis. Inclusion criteria were randomized controlled trials (RCTs) in which patients with osteoporosis, and VCFs were treated with vertebroplasty/kyphoplasty or conservative management. Outcome measures were pain, function, and quality of life. Standardized differences in means were calculated as a measure of effect size. Main results: Ten RCTs were included. The total number of patients in the treatment and control groups was 626 and 628, respectively, the mean patient age ranged from 64 to 80 years, and the majority was female. Vertebroplasty/kyphoplasty was associated with greater pain relief (pooled standardized difference in means = 0.82, 95% confidence interval [CI]: 0.374–1.266, P < 0.001) and a significant improvement in daily function (pooled standardized difference in means = 1.273, 95% CI: 1.028–1.518, P < 0.001) as compared with conservative treatment. The pooled estimate indicated vertebroplasty/kyphoplasty was associated with higher quality of life (pooled standardized difference in means = 1.545, 95% CI: 1.293–1.798, P < 0.001). Subgroup analysis of 8 vertebroplasty studies and 2 kyphoplasty studies that reported pain data, however, indicated that vertebroplasty provided greater pain relief than conservative treatment but kyphoplasty did not. Conclusion: Vertebroplasty may provide better pain relief than balloon

    Osteoporotic sacral fractures, including acute and chronic insufficiency fractures, are increasing in frequency and present a number of management problem. Many of these patients are treated nonoperatively with relative immobility (eg, bedrest, wheelchair, or weight-bearing restrictions) and analgesics, which likely make the osteoporotic component worse. Surgery in this patient population may be desirable in some cases with the goals of improving mobility, relieving pain, and healing in an aligned position while minimizing deformity progression. However, internal fixation of the osteoporotic pelvis can be difficult. Large unicortical lag screws are the workhorse of posterior pelvic fixation, and yet fixation in cancellous bone corridors of an osteoporotic sacrum seems unlikely to achieve optimal fixation. As a result, the operative management and clinical results of these difficult injuries may not be uniformly successful. The authors present a technique for treating osteoporotic patients with a sacral fracture when operative treatment is indicated using percutaneous screw fixation combined with screw augmentation using a resorbable calcium phosphate bone substitute or "cement." The guide wire for a 7.3-mm or other large cannulated lag screw is fully inserted along the desired bony sacral corridor as is standard. The lag screw is then inserted over the wire to the depth where cement is desired. The guide wire is removed, and the aqueous calcium phosphate is injected through the screw's cannulation. For acute fractures, cement was applied to the areas distant to the fracture; whereas in insufficiency fractures, the cement was inserted along most of the screw path. The guide wire then can be reinserted and the lag screw fully inserted. The rationale for using these 2 modalities is their synergistic effect: the cannulated screw provides typical screw fixation and also a conduit for cement application. The cement augments the lag screw's purchase in osteoporotic bone

    Hip fractures are described by increased mortality, loss of quality of life, functional decline and burden of diseases. They show a growing number worldwide. The aim of the present study is to summarise the existing data on the incidence, mortality, complications and rehabilitation of hip fractures, which relevance is reported only by few studies. To reduce mortality and complications of hip fractures the authors emphasize the importance of primary treatment within 12 hours, appropriate selection of surgical methods corresponding to the fracture type after the assessment of femoral head viability, vitamin D supplementation, same conditions for primary treatment during everyday of the week, and an adequate acute treatment and rehabilitation for patient's general health status. In the future integrated processing of multidisciplinary results of hip fractures based on Hungarian data can support the development of efficient treatment and prevention strategies, which can be advantageous for the patient, families, health care system, and the society, too, by the reduction of costly complications of hip fracture healing and mortality.

    Osteoporosis represents one major health condition for our growing elderly population. It accounts for severe morbidity and increased mortality in postmenopausal women and it is becoming an emerging health concern even in aging men. Screening of the population at risk for bone degeneration and treatment assessment of osteoporotic patients to prevent bone fragility fractures represent useful tools to improve quality of life in the elderly and to lighten the related socio-economic impact. Bone mineral density (BMD) estimate by means of dual-energy X-ray absorptiometry is normally used in clinical practice for osteoporosis diagnosis. Nevertheless, BMD alone does not represent a good predictor of fracture risk. From a clinical point of view, bone microarchitecture seems to be an intriguing aspect to characterize bone alteration patterns in aging and pathology. The widening into clinical practice of medical imaging techniques and the impressive advances in information technologies together with enhanced capacity of power calculation have promoted proliferation of new methods to assess changes of trabecular bone architecture (TBA) during aging and osteoporosis. Magnetic resonance imaging (MRI) has recently arisen as a useful tool to measure bone structure in vivo. In particular, high-resolution MRI techniques have introduced new perspectives for TBA characterization by non-invasive non-ionizing methods. However, texture analysis methods have not found favor with clinicians as they produce quite a few parameters whose interpretation is difficult. The introduction in biomedical field of paradigms, such as theory of complexity, chaos, and fractals, suggests new approaches and provides innovative tools to develop computerized methods that, by producing a limited number of parameters sensitive to pathology onset and progression, would speed up their application into clinical practice. Complexity of living beings and fractality of several physio-anatomic structures suggest

    Experimental and epidemiologic data suggest that carotenoids in vegetables and fruits may benefit bone health due to their antioxidant properties. The relationship between dietary total and specific carotenoids, as well as vegetables and fruits, and risk of hip fracture was examined among Chinese in Singapore. We used data from the Singapore Chinese Health Study, a prospective cohort of 63,257 men and women who were of ages 45 to 74 years between 1993 and 1998. At recruitment, subjects were interviewed on lifestyle factors and medical history. Usual diet was measured using a validated food frequency questionnaire. During a mean follow-up of 9.9 years, we identified 1630 hip fracture incident cases. Among men, consumption of vegetables was associated with lower hip fracture risk. Similarly, dietary total carotenoids and specific carotenoids, α-carotene, β-carotene, and lutein/zeaxanthin were inversely associated with hip fracture risk. Compared to men in the lowest quartile of nutrient density, men in the highest quartile had statistically significant 26% to 39% risk reduction (all p for trend <0.05). When stratified by body mass index (BMI), the greatest protective effects of total vegetables and carotenoids were found in men with BMI <20 kg/m(2) (p for trend ≤0.004). There was no association between dietary carotenoids or vegetables/fruits and hip fracture risk among women. This study suggests that adequate intake of vegetables may reduce risk of osteoporotic fractures among elderly men and that the antioxidant effects of carotenoids may counteract the mechanism of osteoporosis related to leanness.

    Hip fractures among the elderly are a common occurrence, with high social and personal costs. Sequelae not infrequently include loss of independent functioning, permanent disability, and death. This prospective study of a cohort of eighty recently diagnosed "hardy" hip fracture patients examines initial rehabilitation expectations using a combination of methods. The study addresses the relationship between initial expectations and changes in ambulatory status from prefracture to three months post-fracture. The importance of previous experience with illness is also explored. Participants who had positive expectations for recovery and those who had greater previous experience were likely to have less negative change in ambulation from prefracture to three months, and better overall ambulation at three months. The findings suggest a relationship between patient expectations for recovery and actual recovery of ambulation, and support the heretofore "clinical impression" that cognition and affect influence the course of rehabilitation after hip fracture.

    Osteoporosis-related hip fractures represent a substantial cause of mortality and morbidity in industrialized countries like Austria. Identification of groups at high risk for mortality after hip fracture is crucial for health policy decisions. To determine in-hospital, long-term, and excess mortality after osteoporosis-related hip fracture in Austrian patients, we conducted a retrospective cohort analysis of pseudonymized invoice data from Austrian social insurance authorities covering roughly 98 % of the entire population. The data set included 31,668 subjects aged 50 years and above sustaining a hip fracture between July 2008 and December 2010 with follow-up until June 2011, and an age-, gender-, and regionally matched control population without hip fractures (56,320 subjects). Kaplan-Meier and Cox hazard regression analyses served to determine unadjusted and adjusted mortality rates: Unadjusted all-cause 1-year mortality amounted to 20.2 % (95 % CI: 19.7-20.7 %). Males had significantly higher long-term, in-hospital, and excess mortality rates than females, but younger males exhibited lower excess mortality than their female counterparts. Advanced age correlated with increased long-term and in-hospital mortality, but lower excess mortality. Excess mortality, particularly in males, was highest in the first 6 months after hip fracture, but remained statistically significantly elevated throughout the observation period of 3 years. Longer hospital stay per fracture was correlated with mortality reduction in older patients and in patients with more subsequent fractures. In conclusion, more efforts are needed to identify causes and effectively prevent excess mortality especially in male osteoporosis patients. PMID:24989776

    Study Design This was designed as a retrospective study. Purpose We assessed the radiographic and clinical outcome of patients who underwent percutaneous vertebroplasty (PVP) in osteoporotic compression fractures with a minimum of 5 years follow-up. Overview of Literature Percutaneous vertebroplasty is effective surgical method for treating osteoporotic compression fracture. Methods Between January 2000 and August 2005, 159 patients were treated with PVP for osteoporotic compression fracture at our department; 43 patients died during follow-up, and 69 patients (121 vertebras) were available for follow-up for over 5 years. We analyzed the clinical and radiologic outcome including cement feature. Results The mean follow-up period was 5.7 years. Clinical outcome by mean visual analogue scale (VAS) score revealed a decreased 4.9 points perioperatively. A decreased score was maintained over 5 years in 46% of patients. A new adjacent vertebral fracture was documented by 33 vertebral bodies in 22 patients. During the follow-up period, 43 patients (38%) in 112 patients died. Anterior body heig ht in the last follow-up was improved about 0.3 mm compared with the preprocedural value, but was not statistically significant. Also, the focal kyphotic angle was reduced from 12.3° at the preprocedural state to 11.7° at the postprocedural state, but was not statistically significant (p > 0.05). Conclusions PVP for osteoporotic compression fracture is an efficient procedure for pain relief by long term follow-up. The cement injected vertebrae showed stable radiologic progression without significant changes in vertebral height or kyphotic angle. PMID:22439082

    Purpose Hip fractures are usually the result of low impact falls and underlying osteoporosis. Since the risk of further fractures in osteoporotic patients can be reduced by between 20 - 70% with bone protection therapy, the NHS is under an obligation to provide effective fracture prevention services for hip fracture patients to reduce risk of further fractures. Evidence suggests there is variation in service organisation. The objective of the study was to explore this variation in more detail by looking at the services provided in one region in England. Methods A questionnaire was designed which included questions around staffing, models of care and how the four components of fracture prevention (case finding, osteoporosis assessment, treatment initiation and adherence (monitoring) were undertaken. We also examined falls prevention services. Clinicians involved in the delivery of osteoporosis services at 11 hospitals in one region in England completed the questionnaire. Results The service overview showed significant variation in service organisation across all aspects of care examined. All sites provided some form of case finding and assessment. However, interesting differences arose when we examined how these components were structured. Eight sites generally initiated treatment in an inpatient setting, two in outpatients and one in primary care. Monitoring was undertaken by secondary care at seven sites and the remainder conducted by GPs. Conclusions The variability in service provision was not explained by local variations in care need. Further work is now needed to establish how the variability in service provision affects key patient, clinical and health economic outcomes. PMID:24964893

    Introduction The mechanism of falling has been proposed as the exclusive explanation for hip fracture pattern. Evidence exists that other genetic factors also influence proximal femoral fracture configuration. The ABO blood group serotype has been associated with other pathologies but any role in hip fracture has yet to be definitively characterised. Methods Our National Hip Fracture Database was interrogated over a four-year period. All patients had their blood group retrieved, and this was compared with hip fracture pattern and mortality rates. Confounding factors were accounted for using logistic regression and the Cox proportional hazards model. Results A total of 2,987 consecutive patients presented to our institution. Those with blood group A were significantly more likely to sustain intracapsular fractures than ‘non-A’ individuals (p=0.009). The blood group distribution of patients with intracapsular fractures was identical to that of the national population of England. However, blood group A was less common in patients with intertrochanteric fractures than in the general population (p=0.0002). Even after correction for age and sex, blood group A was associated with a decrease in the odds of suffering an intertrochanteric fracture to 80% (p=0.002). Blood group A had inferior survivorship correcting for age, sex and hip fracture pattern (hazard ratio: 1.14, p=0.035). This may be due to associated increased prevalence of co-morbid disease in this cohort. Conclusions Blood group is an independent predictor of hip fracture pattern, with group A patients more likely to sustain an intracapsular fracture and non-A individuals more likely to sustain an intertrochanteric fracture. The determinants of fracture pattern are likely to be related to complex interactions at a molecular level based on genetic susceptibility. The mechanism of fall may not be the only aetiological determinant of proximal femoral fracture configuration. PMID:25198976

    The augmentation of fixation with bone cement is increasingly being used in the treatment of severe osteoporotic fractures. We investigated the influence of bone quality on the mechanics of augmentation of plate fixation in a distal femoral fracture model (AO 33 A3 type). Eight osteoporotic and eight non-osteoporotic femoral models were randomly assigned to either an augmented or a non-augmented group. Fixation was performed using a locking compression plate. In the augmented group additionally 1 ml of bone cement was injected into the screw hole before insertion of the screw. Biomechanical testing was performed in axial sinusoidal loading. Augmentation significantly reduced the cut-out distance in the osteoporotic models by about 67% (non-augmented mean 0.30 mm (sd 0.08) vs augmented 0.13 mm (sd 0.06); p = 0.017). There was no statistical reduction in this distance following augmentation in the non-osteoporotic models (non-augmented mean 0.15 mm (sd 0.02) vs augmented 0.15 mm (sd 0.07); p = 0.915). In the osteoporotic models, augmentation significantly increased stability (p = 0.017). PMID:24078541

    To assess the immediate efficacy of percutaneous vertebroplasty (PVP) in relief of pain and improving mobility of patients with vertebral compression fractures (VCF) secondary to osteoporosis, 205 cases (175 patients) underwent 250 percutaneous injections of polymethylmethacrylate (PMMA; unilateral, 247 levels; bilateral, 3 levels) into vertebrae under CT and fluoroscopic guidance for 34 months. Patients were prospectively asked to quantify their pain on a visual analog scale (VAS) before and a day after PVP. The interval to mobilization was recorded in those who were immobilized because of pain and/or bed-rest therapy (115 cases). PVP was technically successful in all patients, with three cases of minimal complications. The mean VAS score available for 196 cases was improved from 7.22+/-1.89 (range, 3-10) to 2.07+/-1.19 (range, 0-10) by PVP. Ninety-four of 115 immobilized cases (81.7%) were mobile by 24 h after PVP, and the mean value was 1.9+/-2.8 days. The incidence of recurrent and new fractures was 15.6% in 4-25 months (mean, 15.3 months). PVP is a safe and effective treatment for relieving the pain associated with osteoporotic VCF and strengthening the vertebrae, avoiding refractures. This therapy leads to early mobilization and avoidance of the dangers of conservative therapy of bed-rest. PMID:15662480

    Ensemble learning methods are one of the most powerful tools for the pattern classification problems. In this paper, the effects of ensemble learning methods and some physical bone densitometry parameters on osteoporotic fracture detection were investigated. Six feature set models were constructed including different physical parameters and they fed into the ensemble classifiers as input features. As ensemble learning techniques, bagging, gradient boosting and random subspace (RSM) were used. Instance based learning (IBk) and random forest (RF) classifiers applied to six feature set models. The patients were classified into three groups such as osteoporosis, osteopenia and control (healthy), using ensemble classifiers. Total classification accuracy and f-measure were also used to evaluate diagnostic performance of the proposed ensemble classification system. The classification accuracy has reached to 98.85 % by the combination of model 6 (five BMD + five T-score values) using RSM-RF classifier. The findings of this paper suggest that the patients will be able to be warned before a bone fracture occurred, by just examining some physical parameters that can easily be measured without invasive operations.

    Coracoid fractures are uncommon, mostly occur at the base or neck of the coracoid process (CP), and typically present with ipsilateral acromioclavicular joint (ACJ) dislocation. However, CP avulsion fractures at the coracoclavicular ligament (CCL) attachment with ACJ dislocation have not been previously reported. A 59-year-old woman receiving glucocorticoid treatment fell from bed and complained of pain in her shoulder. Radiographs revealed an ACJ dislocation with a distal clavicle fracture. Three-dimensional computed tomography (3D-CT) reconstruction showed a small bone fragment at the medial apex of the CP. She was treated conservatively and achieved a satisfactory outcome. CP avulsion fractures at the CCL attachment can occur in osteoporotic patients with ACJ dislocations. Three-dimensional computed tomography is useful for identifying this fracture type. CP avulsion fractures should be suspected in patients with ACJ dislocations and risk factors for osteoporosis or osteopenia. PMID:27493819

    Purpose. To investigate the risk factors and relative risk of new compression fractures following vertebroplasty. Methods. Initially, we enrolled 104 consecutive patients with vertebral compression fractures caused by osteoporosis. A total of 83 of the 104 patients visited our hospital for follow-up examinations for more than 4 weeks after vertebroplasty. Logistic regression analysis of the data obtained from these 83 patients was used to determine relative risks of recurrent compression fractures, using 13 different factors. Results. We identified 59 new fractures in 30 of the 83 patients: 41 new fractures in vertebrae adjacent to treated vertebrae; and 18 new fractures in vertebrae not adjacent to treated vertebrae. New fractures occurred in vertebrae adjacent to treated vertebrae significantly more frequently than in vertebrae not adjacent to treated vertebrae. Only cement leakage into the disk was a significant predictor of new vertebral body fracture after vertebroplasty (odds ratio = 4.633). None of the following covariates were associated with increased risk of new fracture: age, gender, bone mineral density, the number of vertebroplasty procedures, the number of vertebrae treated per procedure, the cumulative number of vertebrae treated, the presence of a single untreated vertebra between treated vertebrae, the presence of multiple untreated vertebrae between treated vertebrae, the amount of bone cement injected per procedure, the cumulative amount of bone cement injected, cement leakage into the soft tissue around the vertebra, and cement leakage into the vein.

    The benefits of bisphosphonates are well documented, but prolonged use has been associated with atypical femur fractures. Radiographic markers for fracture predisposition could potentially aid in safer medication use. In this case-control designed study, we compared hip radiographic parameters and the demographic characteristics of chronic bisphosphonate users who sustained an atypical femoral fracture with a group of chronic bisphosphonate users who did not sustain an atypical femur fracture and also a group who sustained an intertrochanteric hip fracture. Radiographic parameters included were neck-shaft angle (NSA), hip-axis length (HAL) and center-edge angle (CE). Multivariate regression was used to evaluate the relationship between radiographic measures and femur fracture. Receiver-operating characteristic analysis determined cut-off points for neck-shaft angle and risk of atypical femur fracture. Ultimately, pre-fracture radiographs of 53 bisphosphonate users who developed atypical fracture were compared with 43 asymptomatic chronic bisphosphonate users and 64 intertrochanteric fracture patients. Duration of bisphosphonate use did not statistically differ between users sustaining atypical fracture and those without fracture (7.9 [±3.5] vs. 7.7 [±3.3] years, p=0.7). Bisphosphonate users who fractured had acute/varus pre-fracture neck-shaft angles (p<0.001), shorter hip-axis length (p<0.01), and narrower center-edge angles (p<0.01). Regression analysis revealed associations between neck-shaft angle (OR=0.89 [95% CI=0.81-0.97; p=0.01), center edge angle (OR=0.89 [95% CI=0.80-0.99]; p=0.03), and BMI (OR=1.15 [95% CI=1.02-1.31; p=0.03) with fracture development. ROC curve analysis (AUC=0.67 [95% CI=0.56-0.79]) determined that a cut-off point for neck-shaft angle <128.3° yielded 69% sensitivity and 63% specificity for development of atypical femoral fracture. Ultimately, an acute/varus angle of the femoral neck, high BMI, and narrow center-edge angle were

    Purpose. This meta-analysis is to assess the effectiveness of teriparatide in fracture healing and clinical function improvement of the osteoporotic patients. Methods. We searched PubMed, Embase, Web of Science, and the Cochrane databases for randomized and quasi-randomized controlled trials comparing teriparatide to placebo, no treatment, or comparator interventions in the osteoporotic patients. Results. Five studies with 251 patients were included. Patients treated with teriparatide therapy had a significant shorter radiological fracture healing time compared with those in the control group (mean difference [MD] −4.54 days, 95% confidence interval [CI] −8.80 to −0.28). Stratified analysis showed that lower limb group had significant shorter healing time (MD −6.24 days, 95% CI −7.20 to −5.29), but upper limb group did not (MD −1 days, 95% CI −2.02 to 0.2). Patients treated with teriparatide therapy showed better functional outcome than those in the control group (standardized mean difference [SMD] −1.02, 95% CI −1.81 to −0.22). Patients with therapy duration over 4 weeks would have better functional outcome (SMD −1.68, 95% CI −2.07 to −1.29). Conclusions. Teriparatide is effective in accelerating fracture healing and improving functional outcome of osteoporotic women. However, more clinical studies are warranted in order to determine whether the results are applicable to males and the clinical indications for teriparatide after osteoporotic fractures.

    ABSTRACT Purpose: Following hip fracture, patients demonstrate greatly reduced walking speeds 1 year later compared with age-matched elders. The purpose of our study was to examine the factors that relate to gait speed in patients after hip fracture. Methods: Forty-two men and women (mean age 79 ± 7.5 years) who sustained a hip fracture participated in this study. Linear regression analysis was used to determine a statistical model that best predicted gait speed, the dependent variable. Gait speed was measured with a computerized gait mat. The independent variables were age, sex, height, weight, time post-fracture, medications, mental status, depression, balance confidence, Medical Outcome Studies, Short Form (SF-36), balance, and lower extremity isometric force. All subjects were discharged from physical therapy services, and measurements were taken, on average, 17 weeks post-fracture. Results: Using stepwise regression, 72% of the variance in gait speed was explained by summed lower extremity strength normalized by body weight, general health (SF-36), and balance confidence (Activities-specific Balance Confidence Scale). Conclusions: Impairments (summed lower extremity strength) and risk factors (perception of general health and balance confidence) are important predictors of gait speed in elders after hip fracture.

    Severe dementia is a life-limiting condition; hip fractures are more common in patients who have dementia. This study outlines the case of a 92-year-old female with severe dementia who sustained a hip fracture. Despite having a terminal diagnosis (severe dementia and hip fracture) and poor premorbid quality of life, she had a life-prolonging surgery. The report outlines issues around treatment options in such circumstances, informed consent and substitute decision-making. The authors propose a ‘goals of care’ approach to manage patients in whom the best treatment is unclear, during their attendance to the emergency department. It is suggested that utilization of such a model may help with substitute decision-making and true informed consent. PMID:26949537

    Objective This cross-sectional study compared three tools for predicting painful new osteoporotic vertebral fractures (PNOVFs) in older Chinese men: bone mineral density (BMD), the Osteoporosis Self-Assessment Tool for Asians (OSTA), and the World Health Organization fracture risk assessment tool (FRAX) (without BMD). Methods Men aged ≥50 years were apportioned to a group for men with fractures who had undergone percutaneous vertebroplasty (n=111), or a control group of healthy men (n=385). Fractures were verified on X-ray and magnetic resonance imaging. BMD T-scores were determined by dual energy X-ray absorptiometry. Diagnosis of osteoporosis was determined by a BMD T-score of ≤2.5 standard deviations below the average for a young adult at peak bone density at the femoral neck, total hip, or L1–L4. Demographic and clinical risk factor data were self-reported through a questionnaire. BMD, OSTA, and FRAX scores were assessed for identifying PNOVFs via receiver-operating characteristic (ROC) curves. Optimal cutoff points, sensitivity, specificity, and areas under the ROC curves (AUCs) were determined. Results Between the men with fractures and the control group, there were significant differences in BMD T-scores (at femoral neck, total hip, and L1–L4), and OSTA and FRAX scores. In those with fractures, only 53.15% satisfied the criteria for osteoporosis. Compared to BMD or OSTA, the FRAX score had the best predictive value for PNOVFs: the AUC of the FRAX score (cutoff =2.9%) was 0.738, and the sensitivity and specificity were 82% and 62%, respectively. Conclusion FRAX may be a valuable tool for identifying PNOVFs in older Chinese men. PMID:27217730

    This review discusses factors affecting recovery following hip fracture in frail older people as well as interventions associated with improved functional recovery. Prefracture function, cognitive status, co-morbidities, depression, nutrition and social support impact recovery and may interact to affect post-fracture outcome. There is mounting evidence that exercise is beneficial following hip fracture with higher-intensity/duration programmes showing more promising outcomes. Pharmacologic management for osteoporosis has benefits in preventing further fractures, and interest is growing in pharmacologic treatments for post-fracture loss of muscle mass and strength. A growing body of evidence suggests that sub-populations - those with cognitive impairment, residing in nursing homes or males - also benefit from rehabilitation after hip fracture. Optimal post-fracture care may entail the use of multiple interventions; however, more work is needed to determine optimal exercise components, duration and intensity as well as exploring the impact of multimodal interventions that combine exercise, pharmacology, nutrition and other interventions.

    This prospective study investigated risk factors for delirium in elderly hip fracture patients that could be recognized by nurses. Data were collected on predisposing and precipitating factors for delirium from 92 elderly patients with a hip fracture. Predisposing factors included age, gender, sensory impairments, functional impairment before the hip fracture, residency before admission, pre-existing cognitive impairment, comorbidities, and medication use. Precipitating factors included factors related to surgery and to the postoperative period. Factors related to surgery included time between admission and surgery, type of surgery, type of anesthesia, duration of surgery and anesthesia, and complications during surgery. Factors studied in the postoperative period were slow recovery, malnutrition, dehydration, addition of three or more medications, introduction of bladder catheter, infections, complications and falls, and use of morphine. Eighteen patients developed delirium, as diagnosed by a geriatrician by using the Diagnostic Statistical Manual-IV criteria. Data on delirious patients were compared with the data on non-delirious patients. The findings confirm that elderly hip fracture patients with premorbid ADL dependency, psychiatric comorbidities (including dementia), and a high number of other comorbid problems are at risk for the development of delirium. Based on these findings, it is recommended that nurses should assess patients' pre-fracture functional and cognitive capacities in an early stage of the hospital stay. Nurses should also be alert to postoperative delirium in "healthy elderly" patients. Monitoring of symptoms postoperatively in all elderly patients is advised. PMID:12764718

    Study Design A prospective consecutive cohort study (follow-up study). Objective Our study investigated whether implantation of an expandable titanium mesh cage (Osseofix®) is a successful and safe minimally invasive therapy for osteoporotic vertebral compression fractures (VCF). Our experiences, clinical and radiological findings after 12 months follow-up are presented. Kypho- and vertebroplasty are well-established minimally invasive procedures for the treatment of osteoporotic VCF. The main complications associated with both procedures are uncontrolled bone cement leakage. Therefore a suitable alternative has been investigated. Methods During June 2010 to May 2011 24 patients were included with 32 osteoporotic VCF (T6 to L4). All of them were stabilized with the Osseofix® system. Preinterventionally we performed X-ray, MRI, and bone density measurements (DXA). Clinical and radiological results were evaluated preop., postop. and after 12 months postop. based on the Oswestry Disability Index (ODI) and the Visual Analogue Scale (VAS), X-ray (Beck Index, Cobb-angle) and CT. Results There was a significant improvement in the mean ODI (70,6% to 30,1%) as well as a significant reduction in pain intensity (VAS) (7,7 to 1,4) after 12 month. The mean kyphotic angle according to Cobb showed significant improvements (11,7° to 10,4°) after 12 months. Postinterventional imaging showed only one case of loss of height in a stabilized vertebral body (3.1%). We saw no changes in posterior vertebral wall or adjacent fractures. Except for one pronounced postoperative hematoma we saw no surgical complications including no cement leakage. Conclusions Stabilization of symptomatic osteoporotic VCF with Osseofix® system is a safe and effective procedure, even in fractures with posterior wall involvement. The clinical mid-term results are good at a very low complication rate. The Osseofix® system is an interesting alternative to the established procedures of cement augmentation

    In recent years, the advent of percutaneous techniques in the management of osteoporotic vertebral compression fractures has proven to be a great step forward in the evolution of patients suffering from this pathology.Vertebroplasty, which was developed in 1984 by Galibert and Deramond, presents the disadvantage of leakage of the cementation material and the impossibility to restore spinal deformity. Kyphoplasty has shown to be almost a definite solution to these problems. The description of the technique, its indications, and the outcomes resulting from our series of 200 vertebral fractures in 128 patients are presented in this paper. PMID:21107953

    Abstract Nonsteroidal anti-inflammatory drugs (NSAIDs) control musculoskeletal pain, but they also cause adverse side effects. The aim of this study is to explore the impact of chronic NSAIDs use on the risk of a second hip fracture (SHFx) after hip fracture surgery. This population-based case-cohort study used the Taiwan National Health Insurance Research Database (NHIRD), which contains data from >99% of the population. From a random sample of 1 million enrollees, we identified 34,725 patients ≥40 years who sustained a first hip fracture and underwent hip fracture surgery between 1999 and 2009. Chronic NSAIDs use is defined as taking NSAIDs for at least 14 days a month for at least 3 months. The main outcome measure is an SHFx. Propensity-score matching was used to control for confounding. Our results revealed that chronic NSAIDs use was a significant risk factor for an SHFx in patients after hip fracture surgery and for adverse side effects that might last for 12 months. Compared with the nonchronic-use cohort (n = 29,764), the adjusted hazard ratio of an SHFx was 2.15 (95% CI: 2.07–2.33) for the chronic-use cohort (n = 4961). The 10-year Kaplan–Meier survival analyses showed that chronic NSAIDs use presented a positive year-postsurgery-dependency effect on the risk of an SHFx in all the selected subgroups of patients (all P ≤ 0.011). In conclusion, chronic NSAIDs use increases the risk of an SHFx after hip fracture surgery. Avoiding chronic NSAIDs use must be emphasized in clinical practice. PMID:26402817

    The association between mental disorders (MDs) and iatrogenic complications after hip fracture surgery has been poorly studied. Among iatrogenic complications, nosocomial infections (NIs) are a major factor in hip fracture surgery. The aim of this paper was to determine whether patients with a MD and a hip fracture develop more NIs after hip surgery than patients with no MD. We studied 912 patients who underwent surgery for a hip fracture (223 patients with a MD who underwent surgery for a hip fracture and 689 control patients without a MD who also underwent surgery for a hip fracture) and followed them after surgery. Univariable and multivariable analyses were performed using simple and multiple logistic regression analysis (confidence interval, crude and adjusted odds ratios, and P value). We found that MDs, gender, and comorbidities were not associated with a higher risk of developing a NI after surgery for a hip fracture. Only age increases the risk of a NI. PMID:20628560

    To identify susceptibility genes for osteoporosis, we conducted an integrative analysis that combined epigenomic elements and previous genome-wide association studies (GWASs) data, followed by validation at population and functional levels, which could identify common regulatory elements and predict new susceptibility genes that are biologically meaningful to osteoporosis. By this approach, we found a set of distinct epigenomic elements significantly enriched or depleted in the promoters of osteoporosis-associated genes, including 4 transcription factor binding sites, 27 histone marks, and 21 chromatin states segmentation types. Using these epigenomic marks, we performed reverse prediction analysis to prioritize the discovery of new candidate genes. Functional enrichment analysis of all the prioritized genes revealed several key osteoporosis related pathways, including Wnt signaling. Genes with high priority were further subjected to validation using available GWASs datasets. Three genes were significantly associated with spine bone mineral density, including BDNF, PDE4D, and SATB2, which all closely related to bone metabolism. The most significant gene BDNF was also associated with osteoporotic fractures. RNA interference revealed that BDNF knockdown can suppress osteoblast differentiation. Our results demonstrated that epigenomic data could be used to indicate common epigenomic marks to discover additional loci with biological functions for osteoporosis. PMID:27465306

    Intravertebral cleft (IVC) is frequently observed in patients with painful osteoporotic vertebral compression fracture (OVCF). Some studies reported the usefulness of percutaneous vertebroplasty (PVP) for treating OVCF with IVC. However, systematic studies are scarce, and their results are conflicting. The purpose of this study was to evaluate the clinical and radiographic results of PVP in the treatment of painful OVCF with IVC. Two hundred ninety-one patients with OVCF with IVC underwent PVP. Back pain was measured using a visual analog scale (VAS), and physical disability was assessed using the Oswestry Disability Index (ODI). Three radiological parameters were assessed: the local kyphotic angle, percentage spinal canal cross-sectional area of compromise, and intravertebral instability of the affected vertebra. The mean follow-up period was 28 months. The mean values for the VAS and ODI were 8.4 and 60.0%, respectively, before PVP, versus 3.9 and 35.4%, respectively, at the final follow-up. The average local kyphotic angle, percentage spinal canal cross-sectional area of compromise, and intravertebral instability were 10.5°, 17.9% and 6.1°, respectively, before PVP and 8.1°, 15.2%, and 0.8°, respectively, at the final follow-up. There were no neurological or systemic complications due to cement leakage. PVP is an effective and safe intervention for treating OVCF with IVC. PMID:26157525

    Introduction: Injuries of the hip joint from pure hip dislocations to fracture dislocations have been described and classified by various authors. These descriptions do not include fracture dislocation of hip associated with fracture of the greater trochanter. Case Report: We report an unusual case of fracture dislocation of hip in which posterior dislocation of hip was associated with fracture of acetabulum, femoral head, femoral neck, greater trochanter and ipsilateral shaft of tibia. The fracture dislocation was managed with open reduction and internal fixation. Such fracture dislocation has not been reported in literature to the best of our knowledge. Conclusion: We believe that fracture dislocations associate with fractures of greater trochanter should be included in current classification systems of fracture dislocations of hip. PMID:27298974

    The conventional treatment for an undisplaced intracapsular hip fracture is internal fixation. A possible alternative treatment is replacement hemiarthroplasty. We have compared the outcomes of an age, sex and co-morbidity matched cohort of 346 patients who have had their undisplaced intracapsular hip fracture treated using cannulated screws with a group of 346 patients who have had a displaced intracapsular fracture treated using a hemiarthroplasty. Patients treated by internal fixation had a shorter operation time (43 versus 67 min), reduced orthopaedic ward stay (11 versus 15 days), lower incidence of peri-operative complications (24 versus 81), and a lower 1-year mortality (19% versus 26%). Additional benefits for the fixation group were less pain at 1 year, less reduction in mobility and lower dependence on walking aids. All these differences were statistically significant. Hemiarthroplasty had a lower re-admission rate (43 versus 14 cases) and re-operation rate (59 versus 22 cases). These results support the use of internal fixation for undisplaced intracapsular fractures and confirm that the final outcome for an undisplaced intracapsular hip fracture is significantly better than for a displaced intracapsular fracture, despite a higher re-operation rate after internal fixation.

    Twenty-eight patients with osteoporotic vertebral compression fractures (OVCF) were treated with single-balloon bipedicular kyphoplasty (Group A), and 40 patients were treated with double-balloon bipedicular kyphoplasty (Group B). Visual Analogue Scale (VAS) score, vertebral height, and kyphotic angle (KA) were evaluated pre-operatively, post-operatively (3 days after surgery) and at final follow-up. Operative time, X-ray exposure frequency and costs were recorded. The mean operative time and X-ray exposure frequency in Group A were greater than in Group B (p<0.05). Significant improvement of the VAS score was noted in each group, and remained unchanged at final follow-up. Mean increases of anterior and middle height of the fractured vertebral body were 5.14mm and 4.14mm in Group A, respectively, and 6.22mm and 5.06mm in Group B, respectively, and the differences between the groups were statistically significant (p<0.05). Mean reduction of KA was 6.9° in Group A and 8.8° in Group B, which was statistically significant (p<0.05). No statistically significant difference was observed in terms of cement leakage between groups. The mean cost of Group A (US$4202) was significantly less than that of Group B (US$6220) (p<0.001). Single-balloon bipedicular kyphoplasty is a safe and cost-effective surgical method for the treatment of OVCF. It can achieve pain relief comparable with double-balloon bipedicular kyphoplasty. However, double-balloon bipedicular kyphoplasty is more efficacious in terms of the restoration of vertebral height and reduction of KA, and the operative time and X-ray exposure frequency are lower.

    Background: Intravertebral cleft is a structural change in osteoporotic vertebral compression fractures (OVCF), which is the manifestation of ischemic vertebral osteonecrosis complicated with fracture nonunion and pseudoarthrosis and appears in the late stage of OVCF. Despite numerous studies on OVCF, few aim to evaluate the clinicoradiological characteristics and clinical significance of intravertebral cleft in OVCF. This study investigates clinicoradiological characteristics of intravertebral cleft in OVCF and the effect on the efficacy of percutaneous balloon kyphoplasty (PKP). Materials and Methods: PKP was performed on 139 OVCF patients without intravertebral cleft (group A) and 44 OVCF patients with intravertebral cleft (group B). The frequency distribution of the affected vertebral body, bone cement infusion volume, imaging manifestation, leakage rate and type, preoperative and postoperative height of the affected vertebral body, visual analog scale (VAS) and Oswestry disability index (ODI) score were evaluated. Results: Significant differences were found in the frequency distribution of the affected vertebral body and bone cement leakage type between the two groups (P < 0.05). However, differences in bone cement infusion volume and leakage rate (P > 0.05) were not detected. In both groups, the postoperative height of the affected vertebral body was significantly improved (P < 0.05). The restoration of vertebral body height in group B was more evident than that in group A (P < 0.05). The preoperative VAS and ODI scores in group B were significantly higher than those in group A (P < 0.05). After surgical treatment, pain relief and daily activity function in both groups were significantly improved (P < 0.05), and no significant difference in postoperative scores was detected between the two groups (P > 0.05). Conclusion: Intravertebral cleft exhibits specific clinical and imaging as well as bone cement formation characteristics. PKP can effectively restore the

    Hip fracture is one of the most serious consequences of falls in the elderly, with a mortality of 10% at one month and 30% at one year. Elderly patients with hip fractures have complex medical, surgical, and rehabilitation needs, and a well-coordinated multidisciplinary team approach is essential for the best outcome. The model of best practice for hip fracture care is set out in the Orthopaedic Blue Book and is incentivised by the best practice tariff. In 2009 to 2010, only 39.6% of our patients were being operated on within 36 hours, 19% achieved best practice tariff [1], and mortality was 7.8%. We were ranked as one of the worst hospitals to achieve best practice tariff [1] and our mortality was average. The orthogeriatrics team at Ashford & St Peter's NHS Trust (SPH) was implemented in 2010. Through a system redesign, regular governance meetings, audits and quality improvement projects, we have managed to improve care for our patients and reduce mortality. Over the last three years we have successfully achieved best care for our hip fracture patients, demonstrating a steady improvement in our attainment of the best practice tariff and a reduction in mortality to 5.3% in 2013, which ranks us amongst the best trusts nationally.

    Osteoporotic vertebral fractures represent a major cause of disability, loss of quality of life and even mortality among the elderly population. Decisions on drug therapy are based on the assessment of risk factors for fracture from bone mineral density (BMD) measurements. A previously developed model, based on the Damage and Fracture Mechanics, was applied for the evaluation of the mechanical magnitudes involved in the fracture process from clinical BMD measurements. BMD evolution in untreated patients and in patients with seven different treatments was analyzed from clinical studies in order to compare the variation in the risk of fracture. The predictive model was applied in a finite element simulation of the whole lumbar spine, obtaining detailed maps of damage and fracture probability, identifying high-risk local zones at vertebral body. For every vertebra, strontium ranelate exhibits the highest decrease, whereas minimum decrease is achieved with oral ibandronate. All the treatments manifest similar trends for every vertebra. Conversely, for the natural BMD evolution, as bone stiffness decreases, the mechanical damage and fracture probability show a significant increase (as it occurs in the natural history of BMD). Vertebral walls and external areas of vertebral end plates are the zones at greatest risk, in coincidence with the typical locations of osteoporotic fractures, characterized by a vertebral crushing due to the collapse of vertebral walls. This methodology could be applied for an individual patient, in order to obtain the trends corresponding to different treatments, in identifying at-risk individuals in early stages of osteoporosis and might be helpful for treatment decisions.

    Summary Objective: to assess the prevalence of the most relevant environmental and individual risk factors in subjects with a recent hip fracture was the aim of this observational study promoted by the Health Authorities of the Regione Veneto (Italy). Methods: patients aged > 60 years of both genders with a recent hip fracture not associated with malignancies, were administered questionnaires on dietary habits, sun exposure, disability score. A complete family, pharmacological and pathology history was collected together with previous falls, details of the fracture index, anthropometric data. In a subgroup of patients blood was taken for the measurements of serum 25 hydroxy-vitamin D (25OHD). Results: the study includes 704 patients (573 women and 131 men). Mean age was 81±8 years (range 60–102). Severe pre-fracture disability was a common feature (58%) associated with multiple co-morbidities (84%), more frequently cardiovascular and neurological diseases, and specific medications. In a large proportion (86%) of the patients environmental or individual risk factors for falling were found. Vitamin D insufficiency was quite common, particularly in the regional Health Districts were strategies for preventing vitamin D deficiency were not implemented. Only a small proportion (17%) of the study population had been evaluate and treated for osteoporosis. Conclusions: in senile patients with a recent hip fracture pre-existing disability, multiple co-morbidities, high risk of falling and inadequate intake of calcium and vitamin D was quite common. Community and case-finding interventions are highly warranted. PMID:22783336

    In patients with hip fractures, in order to reduce the high number of general complications and those associated with the specific treatment, the functional loss and cognitive impairment, implementation of co-ordinated, multidisciplinary treatment pathways, and rehabilitation, is mandatory. The imminent treatment of proximal femoral fracture consists of major orthopaedic surgery in most cases (total or partial hip arthroplasty, osteosynthesis). After the diagnosis of a hip fracture, an adequate pain medication should be initiated. The decision making for the fracture treatment includes fracture type, patient's age, cognitive function, mobility before the fall and functional demands of the patient in the context of patients life expectancy and goals of care. The anaesthesiological evaluation focuses on risk assessment. Medical abnormalities should be optimized within 24 to 48 h, or an increased perioperative risk due to comorbidities has to be accepted. The timing and the course of further preoperative diagnostic examinations and therapeutic interventions should be co-ordinated between the involved medical disciplines. After the operation a structured screening for delirium should be initiated and further evaluation of patient's nutrition, fall-associated medication, living conditions and osteoporosis treatment has to be performed.

    Introduction Despite high rates of hip fracture among United States (US) nursing home (NH) residents, little is known about geographic variation in hip fracture incidence. We used nationally representative data to identify geographic variation in hip fracture among US NH residents. Design and setting Retrospective cohort study using Part A claims for a 100% of Medicare enrollees in 15,289 NHs linked to NH minimum data set and Online Survey, Certification, and Reporting databases. Participants A total of 891,085 long-stay (continuous residence of ≥100 days) NH residents ≥65 years old. Measurements Medicare Part A claims documenting a hip fracture. Mean incidence rates of hip fracture for long-stay NH residents were calculated for each state and US Census Division from 2007 to 2010. Results The age-, sex-, and race-adjusted incidence rate of hip fracture ranged from 1.49 hip fractures/100 person-years (Hawaii) to 3.60 hip fractures/100 person-years (New Mexico), with a mean of 2.38 (standard deviation 0.43) hip fractures/100 person-years. The mean incidence of hip fracture was 1.7-fold greater in the highest quintile than the lowest. Conclusions We observed modest US state and regional variation in hip fracture incidence among long-stay NH residents. Future studies should assess whether state policies or NH characteristics explain the variation. PMID:27461867

    Objectives To determine whether the use of total hip arthroplasty (THA) among individuals with a displaced intracapsular fracture of the femoral neck is based on national guidelines or if there are systematic inequalities. Design Observational cohort study using the National Hip Fracture Database (NHFD). Setting All hospitals that treat adults with hip fractures in England, Wales, and Northern Ireland. Participants Patients within the national database (all aged ≥60) who received operative treatment for a non-pathological displaced intracapsular hip fracture from 1 July 2011 to 31 April 2015. Main outcome measures Provision of THA to patients considered eligible under criteria published by the National Institute for Health and Care Excellence (NICE). Results 114 119 patients with hip fracture were included, 11 683 (10.2%) of whom underwent THA. Of those who satisfied the NICE criteria, 32% (6780)received a THA. Of patients who underwent THA, 42% (4903) did not satisfy the NICE criteria. A recursive partitioning algorithm found that the NICE eligibility criteria did not optimally explain which patients underwent THA. A model with superior explanatory power drew distinctions that are not supported by NICE, which were an age cut off at 76 and a different ambulation cut off. Among patients who satisfied the NICE eligibility, the use of THA was less likely with higher age (odds ratio 0.88, 95% confidence interval 0.87 to 0.88), worsening abbreviated mental test scores (0.49 (0.41 to 0.58) for normal cognition v borderline cognitive impairment)), worsening American Society of Anesthesiologists score (0.74, 0.66 to 0.84), male sex (0.85, 0.77 to 0.93), worsening ambulatory status (0.32, 0.28 to 0.35 for walking with a stick v independent ambulation), and fifths of worsening socioeconomic area deprivation (0.76 (0.66 to 0.88) for least v most deprived fifth). Patients receiving treatment during the working week were more likely to receive THA than at the

    Objective. To assess the prevalence, clinical and laboratory characteristics, and short-term outcomes of poststroke hip fracture (HF). Methods. A cross-sectional study of 761 consecutive patients aged ≥60 years (82.3 ± 8.8 years; 75% females) with osteoporotic HF. Results. The prevalence of poststroke HF was 13.1% occurring on average 2.4 years after the stroke. The poststroke group compared to the rest of the cohort had a higher proportion of women, subjects with dementia, history of TIA, hypertension, coronary artery disease, secondary hyperparathyroidism, higher serum vitamin B12 levels (>350 pmol/L), walking aid users, and living in residential care facilities. The majority of poststroke HF patients had vitamin D insufficiency (68%) and excess bone resorption (90%). This group had a 3-fold higher incidence of postoperative myocardial injury and need for institutionalisation. In multivariate analysis, independent indicators of poststroke HF were female sex (OR 3.6), history of TIA (OR 5.2), dementia (OR 4.1), hypertension (OR 3.2), use of walking aid (OR 2.5), and higher vitamin B12 level (OR 2.3). Only 15% of poststroke patients received antiosteoporotic therapy prior to HF. Conclusions. Approximately one in seven HFs occurs in older stroke survivors and are associated with poorer outcomes. Early implementation of fracture prevention strategies is needed. PMID:24187647

    An unusual case of undetected ceramic fracture was discovered by coincidence during total hip arthroplasty revision for sepsis. To our knowledge, this kind of fracture has never been described before. The cup liner was broken in 2 parts, consisting of a large outer annulus and a smaller round central piece that was detached from the superior and posterior part of the cup, creating a hole in the cup. The analysis of the retrievals suggests that the fracture occurred during walking at the contact point between the head and the cup. The ceramic breakage was asymptomatic with no mechanical disorder, suggesting that some ceramic fracture may be tolerated in vivo. However, any evidence of a fractured ceramic component should cause the surgeon to strongly consider revision. PMID:19577892

    Study Design Retrospective evaluation. Purpose To compare quality of life in postmenopausal women with osteoporotic vertebral fractures (OVFs) who underwent vertebroplasty (VP) or kyphoplasty (KP). Overview of Literature Patient with OVFs who do not respond to conservative treatment can be treated with VP or ballon KP for faster pain relief. There are controversies on which procedure is more effective. Methods Five hundred twenty-eight postmenopausal women in nationwide hospitals with age of 50 years or older who underwent VP of KP for OVFs were enrolled in this study. Health related quality of life was measured using the European Quality of Life 5 Domains (EQ-5D) and visual analogue scale (VAS). Results In the VP group, average EQ-5D dimension was 1.95 in mobility, 1.86 in self care, 2.02 in usual activity, 2.19 in pain, 1.69 in anxiety or depression. In the KP group, average EQ-5D dimension was 1.83 in mobility, 1.78 in self care, 1.98 in usual activity, 2.03 in pain, 1.55 in anxiety or depression. Quality of life of KP group was significantly better than that of the VP group in mobility (p=0.016), pain (p=0.001), and anxiety or depression (p=0.008). Average EQ-5D index of the VP and the KP group was 0.353 (±0.472) and 0.485 (±0.357), respectively. The EQ-5D index of the KP group was significantly (p<0.001) higher than that of the KP group. The difference of VAS between VP and KP group was not statistically significant (p=0.580). Conclusions Quality of life in patient with OVFs who underwent KP was significantly better than that of patients who underwent VP. PMID:25558323

    Study Design Retrospective study. Purpose This study was conducted to compare vertebral body height restoration rate in rheumatoid arthritis (RA) patients who had undergone percutaneous balloon kyphoplasty (KP) with that of control group who had matched age, sex, body mass index, and bone mineral density. Overview of Literature There is no report on result of KP in RA patients. Methods Postoperative height restoration rate of RA group consisting of 15 patients (18 vertebral bodies) who had undergone KP due to osteoporotic vertebral compression fracture with a 30% or higher vertebral compression rate between May 2005 and January 2013 were compared to control group consisting of 38 patients (39 vertebral bodies) who had matched age, sex, body mass index, and bone mineral density. Results No statically significant difference in age (p=0.846), sex (p=0.366), body mass index (p=0.826), bone mineral density (p=0.349), time to surgery (p=0.528), polymethylmethacrylate injection time (p=0.298), or amount (p=0.830) was found between the RA group and the control group. However, preoperative compression rate in the RA group was significantly (p=0.025) higher compared to that in the control group. In addition, postoperative height restoration rate showed significant correlation with the RA group (p=0.008). Although higher incidence of recollapse occurred in the RA group compared to that in the control group, the difference was not statistically significant (p=0.305). Conclusions Compared to the control group, RA patients showed higher compression rate and higher vertebral restoration rate after KP, indirectly indicating weaker bone quality in patients with RA. Higher incidence of recollapse occurred in the RA group compared to that in the control group, although it was not statistically significant. PMID:26240718

    Background and Purpose: Pain after hip fracture repair is related to worse functional outcomes and higher fracture care costs than that for patients with no or less pain. However, to our knowledge, few studies have examined the roles of hip fracture type or surgical procedure as factors influencing postoperative pain or opioid analgesic requirements. Our goal was to determine whether the type of hip fracture or hip fracture repair affects postoperative pain or opioid analgesic requirements in the elderly patient. Methods: We conducted a retrospective review of 231 patients ≥65 years old admitted to a hip fracture center for surgical repair. Fracture patterns were classified into femoral neck (FN) versus intertrochanteric (IT), stable versus unstable, and type of surgical repair. Demographic and intraoperative variables, postoperative pain scores, and opioid analgesic use data were collected and analyzed according to the type of hip fracture and type of surgical repair. Results: There were no differences in postoperative pain when comparing FN versus IT fractures, stable versus unstable fractures, or type of surgical repair. Patients with FN fractures had higher analgesic requirements on postoperative days 1, 2, and 3. There was no difference in postoperative analgesic requirements among patients with stable versus unstable fractures or type of surgical repair. Otherwise, there were no differences in postoperative pain or opioid analgesic use based on the surgical repair or fracture type. Overall, patients with hip fracture experienced low levels of pain.

    Introduction: Hip fractures, which are common among old patients, are classified into two groups: intracapsular and extracapsular fractures. Extracapsular fractures can be treated with extramedullary implants [e.g. dynamic hip screw (DHS)] or intramedullary nails. Dynamic hip screw is the treatment of choice in stable pertrochanteric fractures. Intrapelvic migration of the sliding screw is a very rare complication. Case Report: We report a case of a 90-year old Caucasian woman who had an unusual intraoperative complication during osteosynthesis procedure for extracapsular hip fracture fixation. In fact, the sliding hip screw went deep into the pelvis during surgery. This mishap required an abdominal surgical approach by the general surgeon to remove the screw. Conclusion: Taking into consideration the poor quality of the bone in very old patients, we emphasize the importance of following every single step of the surgical procedure, in order to minimize the risk of this complication.

    Background Painful hip following hip dislocation or acetabular fracture can be an important signal for early degeneration and progression to osteoarthritis due to intraarticular pathology. However, there is limited literature discussing the use of arthroscopy for the treatment of painful hip. The purpose of this retrospective study was to analyze the effectiveness and benefit of arthroscopic treatment for patients with a painful hip after major trauma. Methods From July 2003 to February 2013, we reviewed 13 patients who underwent arthroscopic treatment after acetabular fracture or hip dislocation and were followed up for a minimum of 2 postoperative years. The degree of osteoarthritis based on the Tonnis classification pre- and postoperatively at final follow-up was determined. Clinical outcomes were evaluated using visual analogue scale for pain (VAS) and modified Harris hip score (MHHS), and range of motion (ROM) of the hip pre- and postoperatively at final follow-up. Results There were nine male and four female patients with a mean age at surgery of 28 years (range, 20 to 50 years). The mean follow-up period of the patients was 59.8 months (range, 24 to 115 months), and the mean interval between initial trauma and arthroscopic treatment was 40.8 months (range, 1 to 144 months). At the final follow-up, VAS and MHHS improved significantly from 6.3 and 53.4 to 3.0 and 88.3, respectively (p = 0.002 and p < 0.001, respectively). However, there were no significant differences in hip flexion, abduction, adduction, external rotation, and internal rotation as minor improvements from 113.1°, 38.5°, 28.5°, 36.5°, and 22.7° to 118.5°, 39.0°, 29.2°, 38.9°, and 26.5° were observed, respectively (p = 0.070, p = 0.414, p = 0.317, p = 0.084, and p = 0.136, respectively). None of the patients exhibited progression of osteoarthritis of the hip at the final follow-up. Conclusions Arthroscopic treatment after acetabular fracture or hip dislocation is effective and delays

    Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (STF) fractures. Methods: In this study, 60 patients who had hip fractures were studied as case studies. They were divided into FNF, ITF and STF groups based on their fracture types (20 patients in each group). Patients were studied with x-ray radiography and CT scans. Radiological parameters including femoral neck length from lateral cortex to center of femoral head (FNL), diameter of femoral head (FHD), diameter of femoral neck (FND), femoral head neck offset (FHNO), neck-shaft angle (alpha), femoral neck anteversion (beta) were measured and compared in all three groups. Results: Amount of FNL was significantly higher in STF group compared to FNF (0.011) while ITF and STF as well as FNT and ITF did not show a significant different. Also, FND in FNF group was significantly lower than the other two groups, i.e. ITF and STF. In other cases there were no instances of significant statistical difference. Conclusion: Hip geometry can be used to identify individuals who are at the risk of fracture with special pattern. Also, it is important to have more studies in different populations and more in men.

    Background We sought to examine the preoperative time for hip stabilization procedure among Hispanics, non-Hispanic blacks (blacks) and non-Hispanic whites (whites). Methods This was a secondary data analysis using Medicare claims data. Our analysis included 40,321 patients admitted for hip fracture hospitalization from 2001-2005. Our primary analysis was generalized linear modeling, and our dependent variable was preoperative time. Our independent variable was race/ethnicity (Hispanics, blacks versus whites), and covariates were age, gender, income, type of hip fracture and comorbidities. Results Bivariate analyses showed that both Hispanics and blacks experienced a longer preoperative time (P<0.01). The average (mean) of days to surgery was 1.2 for whites, 1.6 for blacks and 1.7 for Hispanics. The delayed preoperative time among Hispanics and blacks persisted after adjusting for covariates. Conclusions The delayed preoperative time among minorities suggests the need to closely monitor care among minorities with hip fracture to determine how to best address their developing needs.

    The aims of the present study were to determine whether a parental history of any fracture or hip fracture specifically are significant risk factors for future fracture in an international setting, and to explore the effects of age, sex and bone mineral density (BMD) on this risk. We studied 34,928 men and women from seven prospectively studied cohorts followed for 134,374 person-years. The cohorts comprised the EPOS/EVOS study, CaMos, the Rotterdam Study, DOES and cohorts at Sheffield, Rochester and Gothenburg. The effect of family history of osteoporotic fracture or of hip fracture in first-degree relatives, BMD and age on all clinical fracture, osteoporotic fracture and hip fracture risk alone was examined using Poisson regression in each cohort and for each sex. The results of the different studies were merged from the weighted beta coefficients. A parental history of fracture was associated with a modest but significantly increased risk of any fracture, osteoporotic fracture and hip fracture in men and women combined. The risk ratio (RR) for any fracture was 1.17 (95% CI=1.07-1.28), for any osteoporotic fracture was 1.18 (95% CI=1.06-1.31), and for hip fracture was 1.49 (95% CI=1.17-1.89). The risk ratio was higher at younger ages but not significantly so. No significant difference in risk was seen between men and women with a parental history for any fracture (RR=1.17 and 1.17, respectively) or for an osteoporotic fracture (RR=1.17 and 1.18, respectively). For hip fracture, the risk ratios were somewhat higher, but not significantly higher, in men than in women (RR=2.02 and 1.38, respectively). A family history of hip fracture in parents was associated with a significant risk both of all osteoporotic fracture (RR 1.54; 95CI=1.25-1.88) and of hip fracture (RR=2.27; 95% CI=1.47-3.49). The risk was not significantly changed when BMD was added to the model. We conclude that a parental history of fracture (particularly a family history of hip fracture) confers an

    Introduction. Current treatment strategies for osteoporotic vertebral compression fractures (VCFs) focus on cement-associated solutions. Complications associated with cement application are leakage, embolism, adjacent fractures, and compromise in bony healing. This study comprises a validated VCF model in osteoporotic sheep in order to (1) evaluate a new cementless fracture fixation technique using titanium mesh implants (TMIs) and (2) demonstrate the healing capabilities in osteoporotic VCFs. Methods. Twelve 5-year-old Merino sheep received ovariectomy, corticosteroid injections, and a calcium/phosphorus/vitamin D-deficient diet for osteoporosis induction. Standardized VCFs (type AO A3.1) were created, reduced, and fixed using intravertebral TMIs. Randomly additional autologous spongiosa grafting (G1) or no augmentation was performed (G2, n = 6 each). Two months postoperatively, macroscopic, micro-CT and biomechanical evaluation assessed bony consolidation. Results. Fracture reduction succeeded in all cases without intraoperative complications. Bony consolidation was proven for all cases with increased amounts of callus development for G2 (58.3%). Micro-CT revealed cage integration. Neither group showed improved results with biomechanical testing. Conclusions. Fracture reduction/fixation using TMIs without cement in osteoporotic sheep lumbar VCF resulted in bony fracture healing. Intravertebral application of autologous spongiosa showed no beneficial effects. The technique is now available for clinical use; thus, it offers an opportunity to abandon cement-associated complications. PMID:27019848

    The Osteoporosis Assessment Questionnaire Short Version (OPAQ-SV) was cross-culturally adapted to measure health-related quality of life in Chinese osteoporotic fracture females and then validated in China for its psychometric properties. Cross-cultural adaptation, including translation of the original OPAQ-SV into Mandarin Chinese language, was performed according to published guidelines. Validation of the newly cross-culturally adapted OPAQ-SV was conducted by sampling 234 Chinese osteoporotic fracture females and also a control group of 235 Chinese osteoporotic females without fractures, producing robust content, construct, and discriminant validation results. Major categories of reliability were also met: the Cronbach alpha coefficient was 0.975, indicating good internal consistency; the test-retest reliability was 0.80; and principal component analysis resulted in a 6-factor structure explaining 75.847 % of the total variance. Further, the Comparative Fit Index result was 0.922 following the modified model confirmatory factor analysis, and the chi-squared test was 1.98. The root mean squared error of approximation was 0.078. Moreover, significant differences were revealed between females with fractures and those without fractures across all domains (p < 0.001). Overall, the newly cross-culturally adapted OPAQ-SV appears to possess adequate validity and reliability and may be utilized in clinical trials to assess the health-related quality of life in Chinese osteoporotic fracture females.

    Changes in extreme meteorological variables and the demographic shift towards an older population have made it important to investigate the association of climate variables and hip fracture by advanced methods in order to determine the climate variables that most affect hip fracture incidence. The nonlinear autoregressive moving average with exogenous variable-generalized autoregressive conditional heteroscedasticity (ARMAX-GARCH) and multivariate GARCH (MGARCH) time series approaches were applied to investigate the nonlinear association between hip fracture rate in female and male patients aged 40-74 and 75+ years and climate variables in the period of 1993-2004, in Montreal, Canada. The models describe 50-56% of daily variation in hip fracture rate and identify snow depth, air temperature, day length and air pressure as the influencing variables on the time-varying mean and variance of the hip fracture rate. The conditional covariance between climate variables and hip fracture rate is increasing exponentially, showing that the effect of climate variables on hip fracture rate is most acute when rates are high and climate conditions are at their worst. In Montreal, climate variables, particularly snow depth and air temperature, appear to be important predictors of hip fracture incidence. The association of climate variables and hip fracture does not seem to change linearly with time, but increases exponentially under harsh climate conditions. The results of this study can be used to provide an adaptive climate-related public health program and ti guide allocation of services for avoiding hip fracture risk. PMID:23722925

    Lewis, G B

    1987-11-01

    Many biographers have discussed the throat cancer that plagued General Ulysses S. Grant toward the end of his life. However, little attention has been focused on his orthopaedic problems. On Christmas Eve in 1883, Grant slipped on an icy walk and fell. Following this accident he was bedridden for weeks and orthopaedically disabled for the remainder of his life. Although biographers have documented this incident, the outcome of the accident has been variously attributed to a sprain, muscle rupture, or simply a lack of exercise. The history of the injury and the nature of the symptoms and disability, which suggest that the General may have sustained a hip fracture, are reviewed with a discussion of the state of hip fracture diagnosis, treatment, and prognosis taken from the textbooks of the period.

    Several DXA-based structural engineering models (SEMs) of the proximal femur have been developed to estimate stress caused by sideway falls. Their usefulness in discriminating hip fracture has not yet been established and we therefore evaluated these models. The hip DXA scans of 51 postmenopausal women with hip fracture (30 femoral neck, 17 trochanteric, and 4 unspecified) and 153 age-, height-, and weight-matched controls were reanalyzed using a special version of Hologic’s software that produced a pixel-by-pixel BMD map. For each map, a curved-beam, a curved composite-beam, and a finite element model were generated to calculate stress within the bone when falling sideways. An index of fracture risk (IFR) was defined over the femoral neck, trochanter, and total hip as the stress divided by the yield stress at each pixel and averaged over the regions of interest. Hip structure analysis (HSA) was also performed using Hologic APEX analysis software. Hip BMD and almost all parameters derived from HSA and SEM were discriminators of hip fracture on their own because their ORs were significantly >1. Because of the high correlation of total hip BMD to HSA and SEM-derived parameters, only the bone width discriminated hip fracture independently from total hip BMD. Judged by the area under the receiver operating characteristics curve, the trochanteric IFR derived from the finite element model was significant better than total hip BMD alone and similar to the total hip BMD plus bone width in discriminating all hip fracture and femoral neck fracture. No index was better than total hip BMD for discriminating trochanteric fractures. In conclusion, the finite element model has the potential to replace hip BMD in discriminating hip fractures.

    2012-01-01

    The annual number of hip fractures worldwide is expected to exceed 6 million by 2050. Currently, nearly 50% of hip fracture patients will develop at least one short-term complication including infection, delirium, venous thromboembolism (VTE), pressure ulcers or cardiovascular events. More than half will experience an adverse long-term outcomes including worsened ambulation or functional status, additional fractures and excess mortality. This paper summarizes current evidence for postoperative interventions attempting to improve these outcomes, including pain management, anemia management, delirium prevention strategies, VTE prophylaxis, rehabilitation type, nutritional supplements, anabolic steroids and secondary fracture prevention. Models of care that have been tested in this population including interdisciplinary orthogeriatric services, clinical pathways and hospitalist care are summarized. In general, good quality evidence supports routine use of VTE prophylaxis, and moderate quality evidence supports multifactorial delirium prevention protocols, and a conservative transfusion strategy. Aggressive pain control with higher doses of opiates and/or regional blocks are associated with lower delirium rates. Low-moderate quality evidence supports the use of clinical pathways, and dedicated orthogeriatric consultative services or wards. After hospital discharge, good quality evidence supports the use of bisphosphonates for secondary fracture prevention and mortality reduction. Rehabilitation services are important, but evidence to guide quantity, type or venue is lacking. Additional research is needed to clarify the role of nutritional supplements, anabolic steroids, home care and psychosocial interventions. PMID:24340216

    While accentuated kyphosis is associated with osteoporosis, it is unknown whether it increases risk of future fractures, independent of bone mineral density (BMD) and vertebral fractures. We examined the associations of baseline Cobb angle kyphosis and 15 year change in kyphosis with incident non-spine fractures using data from the Study of Osteoporotic Fractures. A total of 994 predominantly white women, aged 65 or older, were randomly sampled from 9,704 original participants to have repeated Cobb angle measurements of kyphosis measured from lateral spine radiographs at baseline and an average of 15 years later. Non-spine fractures, confirmed by radiographic report, were assessed every four months for up to 21.3 years. Compared with women in the lower three quartiles of kyphosis, women with kyphosis greater than 53 degrees (top quartile) had a 50% increased risk of non-spine fracture (95% CI, 1.10 –2.06 after adjusting for BMD, prevalent vertebral fractures, prior history of fractures, and other fracture risk factors. Cobb angle kyphosis progressed an average of 7 degrees (SD = 6.8) over 15 years. Per 1 SD increase in kyphosis change, there was a multivariable adjusted 28% increased risk of fracture (95% CI, 1.06 – 1.55) that was attenuated by further adjustment for baseline BMD (HR per SD increase in kyphosis change, 1.19; 95% CI 0.99 –1.44). Greater kyphosis is associated with an elevated non-spine fracture risk independent of traditional fracture risk factors in older women. Furthermore, worsening kyphosis is also associated with increased fracture risk that is partially mediated by low baseline BMD that itself is a risk factor for kyphosis progression. These results suggest that randomized controlled fracture intervention trials should consider implementing kyphosis measures to: 1) further study kyphosis and kyphosis change as an additional fracture risk factor; and 2) test whether therapies may improve or delay its progression.

    Vertebral fracture is often seen in osteoporotic patients. Teriparatide is expected to promote bone union. Therefore, we evaluated the action of vertebral collapse prevention by administering teriparatide to vertebral fracture patients. Thirty-four patients with fresh vertebral fracture (48 vertebrae) participated in this study. They were administered either teriparatide (daily 20 µg/day or weekly 56.5 µg/week) or risedronate (17.5 mg/week): ten patients (20 vertebrae) received teriparatide daily (Daily group), 11 patients (15 vertebrae) received teriparatide weekly (Weekly group), and 13 patients (14 vertebrae) received risedronate (RIS group). We compared some laboratory examination items, visual analogue scale (VAS) of low back pain, vertebral collapse rate and local kyphotic angle, and the cleft frequency. In addition, we evaluated 22 vertebral fracture patients (24 vertebrae) who did not take any osteoporotic medicines (Control group). There was no significant difference in any of the scores at the start of treatment. At 8 and 12 weeks after the initial visit, VAS scores in the Daily and Weekly groups were significantly lower than in the RIS group (p < 0.05). At 8 and 12 weeks, the vertebral collapse rate and local kyphotic angle in the Daily group were significantly lower than in the RIS and Control groups (p < 0.01 and p < 0.05, respectively), and those in the Weekly group were significantly lower than in the Control group (p < 0.05). The cleft frequency in the Daily group was significantly lower than in the RIS group (p < 0.05). Teriparatide is promising for the prevention of vertebral collapse progression after vertebral fracture. PMID:25773046

    Summary Temporal trends in hip fracture incidence have recently been reported in some developed countries. Such data in Spain has previously been incomplete; this study reports the stratified incidence of hip fractures in people over 65 in Spain during the last 14 years. Introduction The main objective is to establish whether temporal trends in hip fracture incidence in Spain exist. Methods Ecological study with data from hospital discharges nationwide. The study includes patients aged ≥ 65 years during a 14-year period (1997-2010). The analysis compares two periods of four years: 1997-2000 (P1) and 2007-2010 (P2). Results There were 119,857 fractures in men and 415,421 in women. Comparing periods (P1 vs P2), over ten years the crude incidence rate/100,000 inhabitant/year increased an average of 2.3%/year in men and 1.4% in women. After adjustment, the rate increased an average of 0.4%/year in men (p<0.0001), but decreased 0.2%/year in women (p<0.0001). In men younger than 85, the decrease was not significant except in 70-74 years and from 80 years the adjusted rate increases significantly (p<0.0001). In women under 80 years of age, the decrease in adjusted rate was significant, there was no change in 80-84 years and the adjusted rate increased significantly in individuals 85 years and older (p<0.0001). Mortality rates declined by 22% in both sexes and the index of overaging population rises 30.1% in men and 25.2% in women. Conclusions This study supports other international studies by showing changes in the incidence of hip fractures after age-population adjustment, which denotes a decrease in the younger age groups and among women and shows an increase in both groups over 85 years. The increase in the crude incidence rate of hip fracture in Spain reflects changes in population structure. PMID:24322478

    Osteoporotic fracture has become a major public health problem, and until today, the treatments available are not satisfactory. While there is growing evidence to support the individual treatment of parathyroid hormone (PTH) administration and low-intensity pulsed ultrasound (LIPUS) exposure as respectively systemic and local therapies during osteoporotic fracture healing, their effects have not yet been investigated when introduced concurrently. This study aimed to evaluate the effects of combined treatment with PTH (1-34) and LIPUS on fracture healing in ovariectomized (OVX) rats. Thirty-two, 12-week-old female Sprague-Dawley rats were OVX to induce osteoporosis. After 12 weeks, the rats underwent surgery to create bilateral mid-diaphyseal fractures of proximal tibiae. All animals were randomly divided into 4 groups (n = 8 for each): control group as placebo, PTH group, LIPUS group, and combined group. PTH group had PTH administration at a dose of 30 μg/kg/day for 3 days/week for 6 weeks. LIPUS group received ultrasound 5 days/week for 20 min/day for 6 weeks and combined group had both PTH administration and LIPUS exposure for 6 weeks. Fracture healing was observed weekly by anteroposterior radiography and micro-CT. Five weeks after the fracture, the tibia were harvested to permit histological assessments and at week 6, for mechanical property of the fracture callus. Micro-CT showed that the PTH and combined groups exhibited significantly higher BMD and trabecular bone integrity than control group at weeks 4-6. Radiography, fracture healing score and mean callus area indicated that the combined group revealed better healing processes than the individual groups. Mechanically, bending moment to failure was significantly higher in LIPUS, PTH and combined groups than in control group. These data suggest that the combined treatment of PTH and LIPUS have been shown to accelerate fracture bone healing and enhance bone properties rather than single agent

    Background The preoperative coexisting chronic systemic illness, delay in surgery, gender, and age were considered as risk factors for the complications after hip fracture surgery. The wider range of surgical delay and immobility-related pulmonary morbidity may affect postoperative complications and mortality. This study examined the risk factors for morbidity and mortality following the hip fracture surgery. Methods The patient data was collected retrospectively. The consecutive 506 patients with hip fracture surgery, aged 60 years or older, were included. The patients' age, gender, preexisting diseases, American Society of Anesthesiologists (ASA) classification, delay in surgical repair, duration of surgical procedure, and methods of anesthesia were noted. The thirty-day postoperative complications were reviewed, and cardiac complications, pulmonary complications, delirium, and death were recorded. The data was analyzed for postoperative complications and risk factors. Results Atelectasis was associated with postoperative pulmonary complications. Male gender and age ≥ 80 years were associated with an increased incidence of postoperative delirium. ASA classification 3 was associated with death. A delay in surgery was not associated with any complications. Preexisting diseases and methods of anesthesia did not affect mortality and postoperative complications. Conclusions The results suggest that a delay in surgery did not affect the postoperative complications and morbidity. PMID:23814650

    Objectives: To study the outcome of hip fractures in a cohort of patients from two different time periods (2002–2003 and 2006–2008). Methods: Patients treated for hip fractures at the St Ann's Bay Regional Hospital, which provides orthopaedic care for the parishes of St Ann, St Mary and Portland, were retrospectively analysed between 2002–2003 and 2006–2008. Results: A significant increase in the recorded incidence of hip fractures, from 19 in the 2002–2003 time period to 101 in the 2006–2008 time period was noted. There was a drastic fall in the in-hospital mortality rate (43% in the 2002–2003 time period compared to 4.5% in the 2006–2008 time period). In the 2006–2008 period, 82.9% of patients were ambulant at discharge compared to 36% from the 2002–2003 time period. Conclusion: Early surgical fixation is necessary to allow rapid mobilization in these patients for whom the consequences of bed rest would otherwise be devastating. PMID:25303247

    Background/Objectives Self-reported physical activity (PA) has been linked to lower hip fracture and fall rates. The objective of this study was to determine the association between objectively measured PA, fractures and falls. Design/Setting/Participants 2731 men (mean age 79 yrs) recruited at 6 US clinical sites into a longitudinal cohort study. Measurements Total and active energy expenditure (EE) and minutes per day spent in sedentary and moderate intensity activities were measured using the multi-sensor SenseWear Pro Armband (SWA)for at least 5 days. Energy expended at a metabolic equivalent (MET >3) was termed active EE. Incident non-spine fractures and falls were identified every 4 months. Results 759 (28.2%) men fell at least once over 12 months of follow-up; 186 (6.8%) men experienced ≥1 fracture over an average follow-up of 3.5± 0.9 years.The association between PA and falling varied by age (p interaction=0.02). Men 80 yrs, with the lowest active EE had a higher risk of falling, RR=1.43, p trend=0.09. In multivariate models including health status, men in the lowest quintile of active EE had a significantly higher risk of fracture, hazard ratio (HR)=1.82 (95% confidence interval (CI) 1.10, 3.00), p trend=0.04. Men with less than 33 minutes/day of moderate activity had a 70% increased risk of fracture, HR=1.70(95% CI, 1.03, 2.80). Conclusion Age modifies the association between PA and falling. Interventions aimed at >30 minutes of moderate PA per day may reduce fracturesextending existing PA guidelines to the oldest old, the fastest growing proportion of those over age 65. PMID:23855842

    Objective Balloon kyphoplasty can effectively relieve the symptomatic pain and correct the segmental deformity of osteoporotic vertebral compression fractures. While many articles have reported on the effectiveness of the procedure, there has not been any research on the factors affecting the deformity correction. Here, we evaluated both the relationship between postoperative pain relief and restoration of the vertebral height, and segmental kyphosis, as well as the various factors affecting segmental deformity correction after balloon kyphoplasty. Methods Between January 2004 and December 2006, 137 patients (158 vertebral levels) underwent balloon kyphoplasty. We analyzed various factors such as the age and sex of the patient, preoperative compression ratio, kyphotic angle of compressed segment, injected PMMA volume, configuration of compression, preoperative bone mineral density (BMD) score, time interval between onset of symptom and the procedure, visual analogue scale (VAS) score for pain rating and surgery-related complications. Results The mean postoperative VAS score improvement was 4.93±0.17. The mean postoperative height restoration rate was 17.8±1.57% and the kyphotic angle reduction was 1.94±0.38°. However, there were no significant statistical correlations among VAS score improvement, height restoration rate, and kyphotic angle reduction. Among the various factors, the configuration of the compressed vertebral body (p=0.002) was related to the height restoration rate and the direction of the compression (p=0.006) was related with the kyphotic angle reduction. The preoperative compression ratio (p=0.023, p=0.006) and injected PMMA volume (p<0.001, p=0.035) affected both the height restoration and kyphotic angle reduction. Only the preoperative compression ratio was found to be as an independent affecting factor (95% CI : 1.064-5.068). Conclusion The two major benefits of balloon kyphoplasty are immediate pain relief and local deformity correction

  4. Accelerated care versus standard care among patients with hip fracture: the HIP ATTACK pilot trial

    PubMed Central

    2014-01-01

    Background: A hip fracture causes bleeding, pain and immobility, and initiates inflammatory, hypercoagulable, catabolic and stress states. Accelerated surgery may improve outcomes by reducing the duration of these states and immobility. We undertook a pilot trial to determine the feasibility of a trial comparing accelerated care (i.e., rapid medical clearance and surgery) and standard care among patients with a hip fracture. Methods: Patients aged 45 years or older who, during weekday, daytime working hours, received a diagnosis of a hip fracture requiring surgery were randomly assigned to receive accelerated or standard care. Our feasibility outcomes included the proportion of eligible patients randomly assigned, completeness of follow-up and timelines of accelerated surgery. The main clinical outcome, assessed by data collectors and adjudicators who were unaware of study group allocations, was a major perioperative complication (i.e., a composite of death, preoperative myocardial infarction, myocardial injury after noncardiac surgery, pulmonary embolism, pneumonia, stroke, and life-threatening or major bleeding) within 30 days of randomization. Results: Of patients eligible for inclusion, 80% consented and were randomly assigned to groups (30 to accelerated care and 30 to standard care) at 2 centres in Canada and 1 centre in India. All patients completed 30-day follow-up. The median time from diagnosis to surgery was 6.0 hours in the accelerated care group and 24.2 hours in the standard care group (p < 0.001). A major perioperative complication occurred in 9 (30%) of the patients in the accelerated care group and 14 (47%) of the patients in the standard care group (hazard ratio 0.60, 95% confidence interval 0.26–1.39). Interpretation: These results show the feasibility of a trial comparing accelerated and standard care among patients with hip fracture and support a definitive trial.

    The aims of this study were to assess the relationship between hip geometry and the 5-yr risk of hip fractures in postmenopausal osteoporotic women and the effects of strontium ranelate on these parameters. Using the 5-yr data of a randomized placebo-controlled trial of strontium ranelate (Treatment of Peripheral Osteoporosis Study [TROPOS]), we reanalyzed the hip dual-energy X-ray absorptiometry scans to determine the role of hip geometry in the risk of hip fractures (placebo group, n=636) and to analyze the effects of strontium ranelate (n=483). The outcomes included the hip structure analysis (HSA) parameters: cross-sectional area (CSA), section modulus, cortical thickness, and buckling ratio, measured at femoral neck, intertrochanteric (IT) region, and proximal shaft. The geometric parameters associated with an increased risk of hip fracture over 5yr were IT CSA and femoral shaft cortical thickness independent of age and total-hip bone mineral density (BMD). Using Bonferroni adjustment, IT cortical thickness was associated with the risk of hip fracture. Over 5yr, significant decreases in some femoral dimensions of the placebo group contrast with significant increases in strontium ranelate group after adjustment for age and BMD. Using Bonferroni adjustment, differences between placebo and strontium ranelate groups were no longer significant after adjustment on 5-yr BMD changes. Some HSA parameters have predictive value for hip fracture risk in postmenopausal osteoporotic women. Strontium ranelate improves some HSA parameters, through the BMD increase. PMID:22321661

    Bone marrow adipose tissue (BMAT) is associated with low bone mass, although the functional consequences for skeletal maintenance of increased BMAT are currently unclear. BMAT might have a role in systemic energy metabolism, and could be an energy source as well as an endocrine organ for neighboring bone cells, releasing cytokines, adipokines and free fatty acids into the bone marrow microenvironment. The aim of the present report was to compare the fatty acid composition in the bone marrow supernatant fluid (BMSF) and blood plasma of postmenopausal women women (65-80 years old). BMSF was obtained after spinning the aspirated bone marrow samples; donors were classified as control, osteopenic or osteoporotic after dual-energy X-ray absorptiometry. Total lipids from human bone marrow fluid and plasma were extracted, converted to the corresponding methyl esters, and finally analyzed by a gas chromatographer coupled with a mass spectrometer. Results showed that fatty acid composition in BMSF was dynamic and distinct from blood plasma, implying significance in the locally produced lipids. The fatty acid composition in the BMSF was enriched in saturated fatty acid and decreased in unsaturated fatty acids as compared to blood plasma, but this relationship switched in women who suffered a hip fracture. On the other hand, there was no relationship between BMSF and bone mineral density. In conclusion, lipid composition of BMSF is distinct from the circulatory compartment, most likely reflecting the energy needs of the marrow compartment. J. Cell.

    Background and purpose The incidence and annual number of hip fractures have increased worldwide during the past 50 years, and projections have indicated a further increase. During the last decade, however, a down-turn in the incidence of hip fracture has been seen in the western world. We predicted the development of hip fractures in Sweden until the year 2050. Methods We reviewed surgical records for the period 2002–2012 in the city of Malmö, Sweden, and identified patients aged 50 years or more with a hip fracture. We estimated incidence rates by using official population figures as denominator and applied the rates to population projections each year until 2050. We also made projections based on our previously published nationwide Swedish hip fracture rates for the period 1987–2002. Since the projections are based on estimates, no confidence limits are given. Results During the period 2002–2012, there were 7,385 hip fractures in Malmö. Based on these data, we predicted that there would be approximately 30,000 hip fractures in Sweden in the year 2050. Use of nationwide rates for 2002 in the predictive model gave similar results, which correspond to an increase in the number of hip fractures by a factor of 1.9 (1.7 for women and 2.3 for men) compared to 2002. Interpretation The annual number of hip fractures will almost double during the first half of the century. Time trends in hip fractures and also changes in population size and age distribution should be continuously monitored, as such changes will influence the number of hip fractures in the future. Our results indicate that we must optimize preventive measures for hip fractures and prepare for major demands in resources. PMID:24786906

    Simultaneous bilateral hip fractures are rare, mostly being caused by violent forces or in patients with bone metabolism disorders. We present the case of an elderly patient who sustained simultaneous bilateral hip fractures following a simple fall without having any known predilecting comorbidities other than advanced age. Only four cases have been described of elderly patients without comorbidity with simultaneous bilateral hip fractures following low-energy traumas. This rareness potentially leads to misses of this diagnosis. PMID:27161143

    2010-11-01

    Percutaneous screw fixation of the anterior column of the acetabulum has been a challenging task because of its unique anatomy and a risk of intra-articular penetration. Evidence is lacking for any tools to provide visual scrutiny of fracture reduction and intra-articular screw penetration. We report 2 cases of fracture of the acetabulum that developed in young female athletes, in which the anterior column was fixed with a percutaneous screw by use of hip arthroscopy as an assisting tool for intra-articular observation. In our experience this method was found to be promising in terms of anatomic reduction of the fracture site, avoiding articular penetration during screw insertion, with additional advantages of joint debridement, lavage, and reduction in radiation exposure.

    Hip fracture, a common complication of fall injuries in older adults, often results in high rate of mortality, increased debility, functional loss, and worse quality of life. The value of geriatric teams and model of care for the hip fracture patients have been examined in a number of studies, and even though most studies have demonstrated potential impact in improving outcomes for the hip fracture patients, they are often observational or quasi-experimental designs that are prone to bias. In this editorial, we review the Lancet article by Prestmo and colleagues, a randomized controlled trial that demonstrated improved outcomes for hip fracture patients managed in a geriatric unit.

    More than 90% of hip fractures in older Americans result from a fall. Inadequate intake of dietary protein and vitamin D are common in older adults, and diets in low these could contribute to loss of muscle mass and strength or coordination, in turn increasing the risk of falling. The objective of the study was to evaluate the relationship between protein and vitamin D intake with the occurrence of falls in older women in the Study of Osteoporotic Fracture, a prospective cohort of more than 4000 postmenopausal women participating from January 1997 to September 1998. Incident falls were ascertained for one year. Protein and vitamin D intake was assessed by a food frequency questionnaire; associations with a reported fall were estimated with logistic regression, adjusted for fall-related covariates and energy. Protein and vitamin D were modeled separately because of high correlation (rho = 0.55, P < 0.001). A total of 1429 women reported a fall within one year. In separate, unadjusted models dietary protein (per 1 g/kg increase) and vitamin D (per 100 International Unit (IU) increase) significantly increased the odds ratio (OR) of falling (OR 1.35 95% CI 1.15-1.59, OR 1.11 95% CI 1.03-1.19, respectively). Once fall-related covariates were added to each model, dietary protein and vitamin D were noncontributory to falls. While we could find no direct association between vitamin D and protein intake and fall prevention, adequate intake of these two nutrients are critical for musculoskeletal health in older adults.

    The increasing problems in the field of osteoporotic fracture fixation results in specialized implants as well as new operation methods, for example, implant augmentation with bone cement. The aim of this study was to determine the biomechanical impact of augmentation in the treatment of osteoporotic distal femur fractures.Seven pairs of osteoporotic fresh frozen distal femora were randomly assigned to either an augmented or nonaugmented group. In both groups, an Orthopaedic Trauma Association 33 A3 fractures was fixed using the locking compression plate distal femur and cannulated and perforated screws. In the augmented group, additionally, 1 mL of polymethylmethacrylate cement was injected through the screw. Prior to mechanical testing, bone mineral density (BMD) and local bone strength were determined. Mechanical testing was performed by cyclic axial loading (100 N to 750 N + 0.05N/cycle) using a servo-hydraulic testing machine.As a result, the BMD as well as the axial stiffness did not significantly differ between the groups. The number of cycles to failure was significantly higher in the augmented group with the BMD as a significant covariate.In conclusion, cement augmentation can significantly improve implant anchorage in plating of osteoporotic distal femur fractures.

    Objectives: to evaluate orthogeriatric and nurse-led fracture liaison service (FLS) models of post-hip fracture care in terms of impact on mortality (30 days and 1 year) and second hip fracture (2 years). Setting: Hospital Episode Statistics database linked to Office for National Statistics mortality records for 11 acute hospitals in a region of England. Population: patients aged over 60 years admitted for a primary hip fracture from 2003 to 2013. Methods: each hospital was analysed separately and acted as its own control in a before–after time-series design in which the appointment of an orthogeriatrician or set-up/expansion of an FLS was evaluated. Multivariable Cox regression (mortality) and competing risk survival models (second hip fracture) were used. Fixed effects meta-analysis was used to pool estimates of impact for interventions of the same type. Results: of 33,152 primary hip fracture patients, 1,288 sustained a second hip fracture within 2 years (age and sex standardised proportion of 4.2%). 3,033 primary hip fracture patients died within 30 days and 9,662 died within 1 year (age and sex standardised proportion of 9.5% and 29.8%, respectively). The estimated impact of introducing an orthogeriatrician on 30-day and 1-year mortality was hazard ratio (HR) = 0.73 (95% CI: 0.65–0.82) and HR = 0.81 (CI: 0.75–0.87), respectively. Following an FLS, these associations were as follows: HR = 0.80 (95% CI: 0.71–0.91) and HR = 0.84 (0.77–0.93). There was no significant impact on time to second hip fracture. Conclusions: the introduction and/or expansion of orthogeriatric and FLS models of post-hip fracture care has a beneficial effect on subsequent mortality. No evidence for a reduction in second hip fracture rate was found. PMID:26802076

    BACKGROUND Mortality is increased after a hip fracture, and strategies that improve outcomes are needed. METHODS In this randomized, double-blind, placebo-controlled trial, 1065 patients were assigned to receive yearly intravenous zoledronic acid (at a dose of 5 mg), and 1062 patients were assigned to receive placebo. The infusions were first administered within 90 days after surgical repair of a hip fracture. All patients received supplemental vitamin D and calcium. The median follow-up was 1.9 years. The primary end point was a new clinical fracture. RESULTS The rates of any new clinical fracture were 8.6% in the zoledronic acid group and 13.9% in the placebo group, a 35% risk reduction (P = 0.001); the respective rates of a new clinical vertebral fracture were 1.7% and 3.8% (P = 0.02), and the respective rates of new nonvertebral fractures were 7.6% and 10.7% (P = 0.03). In the safety analysis, 101 of 1054 patients in the zoledronic acid group (9.6%) and 141 of 1057 patients in the placebo group (13.3%) died, a reduction of 28% in deaths from any cause in the zoledronic-acid group (P = 0.01). The most frequent adverse events in patients receiving zoledronic acid were pyrexia, myalgia, and bone and musculoskeletal pain. No cases of osteonecrosis of the jaw were reported, and no adverse effects on the healing of fractures were noted. The rates of renal and cardiovascular adverse events, including atrial fibrillation and stroke, were similar in the two groups. CONCLUSIONS An annual infusion of zoledronic acid within 90 days after repair of a low-trauma hip fracture was associated with a reduction in the rate of new clinical fractures and improved survival.

    Geriatric hip fractures are a challenging clinical problem throughout the world. Hip fracture services have been shown to shorten time to surgery, decrease the cost of admissions, and improve the outcomes. We instituted a geriatric hip fracture program for comanagement of these injuries by orthopedic and internal medicine teams at our hospital in India. From January 2010 till December 2011, 119 patients with a femoral neck fracture were treated with cemented modular hemiarthroplasty under this program using a cost-effective Indian implant. The cohort included 63 males and 56 females with a mean age of 70.7 years (range 55-98 years). Hypertension (n = 42) and diabetes mellitus (n = 29) were the most common comorbidities. The follow-up period ranged from 12 to 37 months with an average of 24 months. The surgery was performed within 24 hours of admission in 60.5% (n = 72) patients. The use of antiplatelet drugs was the most common reason for delay of surgery. The mean length of hospital stay was 10.4 days (range 3-24 days) with 77% (n = 92) of patients discharged within 1 week of admission. On follow-up, good to excellent Harris hip scores were seen in 88% of patients with 76% of patients returning to the preinjury ambulatory status. The mortality rate was 6% at 6 months follow-up and 10.9% at 2 years. Our study shows that a hip fracture program can be instituted in India. The program helped us in achieving the goal of early surgery, mobilization, and discharge from hospital with decreased mortality. PMID:26246953

    Summary The Tuscany Region was the first Italian Region to initiate a program for the prevention of hip fractures in over 65 year old. The T.A.R.Ge.T. project “Appropriate treatment of geriatric re-fractures in Tuscany” (Trattamento Appropriato delle Rifratture Geriatriche in Toscana), which is still on-going, includes a preliminary phase (2009–2010) for baseline analysis and education of the participating centers and a 4-year-prospective phase (2011–2014). The monitoring system is performed horizontally analyzing 5 different flows: SDO (Performance Hospitalization), SPF (Pharmaceutical Distribution Dataset), FED (Direct Distribution Dataset), SAA (Registry of Patients), SPA (Specialized Outpatient) flows. In this review will be shown some of the most important results of analyzes of the retrospective phase. Between 2006 and 2011 only 26% of hip fractured patients has being treated with anti-osteoporotic drugs. The percentage of treatment increases 10% after the second fracture. Until 2011 there wasn’t in Tuscany a prevention program of bone fragility; patients were treated with specific treatment only in severe cases: this phenomenon implies that mortality and re-fracture are higher on treated patients than in patients who did not have any kind of treatment. The treated patients are the most severe and therefore they have a higher risk of death and re-fracture. PMID:26136794

    The impact of celiac disease autoimmunity on bone health is unclear. We investigated the associations of seropositivity for tissue transglutaminase antibodies (tTGA) and endomysial antibodies (EMA) with incident hip fractures using data from a prospective cohort study, Mini-Finland Health Survey. Baseline serum samples, taken in 1978-80, were tested for tTGA and EMA. Incident hip fractures up to the year 2011 were ascertained from a national hospitalization register. Associations between seropositivity and hip fractures were modeled using Cox proportional hazards regression adjusted for age, sex, body mass index, vitamin D, gamma-glutamyl transferase, smoking, and self-rated health. Our analyses were based on 6919 men and women who had no record of celiac disease or hip fracture before the study baseline. A total of 382 individuals had a hip fracture during a median follow-up of 30 years. Compared with the tTGA-negative individuals (n = 6350), tTGA-positive participants (n = 569; with hip fracture, n = 51) had a higher risk of hip fractures (hazard ratio [HR] = 1.59, 95% confidence interval [CI] 1.17, 2.14). The findings were similar for another tTGA test (n 200; with hip fracture, n = 26; HR = 2.23, 95% CI 1.49, 3.34). We found no evidence for an association between EMA positivity and hip fracture risk (HR = 0.92, 95% CI 0.34, 2.47; n = 74; with hip fracture, n = 4). In our prospective population-based study of Finnish adults, seropositivity for tTGA was associated with an increased hip fracture risk. PMID:25270967

    Background Elderly nursing home residents are at increased risk of hip fracture; however, the efficacy of fracture prevention strategies in this population is unclear. Objective We performed a scoping review of randomized controlled trials of interventions tested in the long-term care (LTC) setting, examining hip fracture outcomes. Methods We searched for citations in 6 respective electronic searches, supplemented by hand searches. Two reviewers independently reviewed all citations and full-text papers; consensus was achieved on final inclusion. Data was abstracted in duplicate. Findings We reviewed 22,349 abstracts or citations and 949 full-text papers. Data from 20 trials were included: 7 - vitamin D (n = 12,875 participants), 2 - sunlight exposure (n = 522), 1 - alendronate (n = 327), 1 - fluoride (n = 460), 4 – exercise or multimodal interventions (n = 8,165), and 5 - hip protectors (n = 2,594). Vitamin D, particularly vitamin D3 ≥800 IU orally daily, reduced hip fracture risk. Hip protectors reduced hip fractures in included studies, although a recent large study not meeting inclusion criteria was negative. Fluoride and sunlight exposure did not significantly reduce hip fractures. Falls were reduced in three studies of exercise or multimodal interventions, with one study suggesting reduced hip fractures in a secondary analysis. A staff education and risk assessment strategy did not significantly reduce falls or hip fractures. In a study underpowered for fracture outcomes, alendronate did not significantly reduce hip fractures in LTC. Conclusions The intervention with the strongest evidence for reduction of hip fractures in LTC is Vitamin D supplementation; more research on other interventions is needed. PMID:20209088

    2015-01-01

    Femoral stem fracture is an uncommon reason for the failure of total hip arthroplasty, with only 16 cases of fully coated stem fractures reported to date. Here we report a case in which a fully coated primary femoral stem fracture occurred after conversion to total hip arthroplasty for the non-union of an intertrochanteric fracture of the femur. Metallurgic evaluation of the etiology and mechanism revealed that the fracture was initiated by fatigue-related failure and completed by ductile failure on the posterior side of the fracture. Considering the recent trend of treating an intertrochanteric fracture with hip arthroplasty, possible stem failure should be considered, since most patients will have at least one of the known risk factors for stem fracture.

    Osteoporosis and osteoporotic fractures represent a substantial health burden, and predominantly affect the elderly. Younger generations may also develop these conditions because of various predisposing conditions, including primary hyperparathyroidism. However, little information is available regarding early skeletal manifestations of primary hyperparathyroidism.A 30-year-old Japanese male presented with pain in his left wrist, and was diagnosed with a distal radius fracture. During surgery, we noticed decreased bone strength of the fracture site. Further investigation found osteoporosis and primary hyperparathyroidism owing to a solitary parathyroid adenoma, which was resected without significant complications. History revealed that the patient suffered a metacarpal bone fracture of his right fifth bone 6 months earlier. Although serial x-rays at that time had shown rapidly developed cortical bone erosion around the fractured finger, the possibility of primary hyperparathyroidism was overlooked because of poor awareness of the condition, leading to a 6-month delay in the diagnosis of primary hyperparathyroidism.Clinicians should be aware that finger fractures may be an early skeletal manifestation of primary hyperparathyroidism that can help achieve a prompt diagnosis of the condition, especially when they occur in young adults in the absence of major trauma.

    We aim to capture and apply 3-dimensional bone fragility features for fracture risk estimation. Using inter-subject image registration, we constructed a hip QCT atlas comprising 37 patients with hip fractures and 38 age-matched controls. In the hip atlas space, we performed principal component analysis to identify the principal components (eigen images) that showed association with hip fracture. To develop and test a hip fracture risk model based on the principal components, we randomly divided the 75 QCT scans into two groups, one serving as the training set and the other as the test set. We applied this model to estimate a fracture risk index for each test subject, and used the fracture risk indices to discriminate the fracture patients and controls. To evaluate the fracture discrimination efficacy, we performed ROC analysis and calculated the AUC (area under curve). When using the first group as the training group and the second as the test group, the AUC was 0.880, compared to conventional fracture risk estimation methods based on bone densitometry, which had AUC values ranging between 0.782 and 0.871. When using the second group as the training group, the AUC was 0.839, compared to densitometric methods with AUC values ranging between 0.767 and 0.807. Our results demonstrate that principal components derived from hip QCT atlas are associated with hip fracture. Use of such features may provide new quantitative measures of interest to osteoporosis.

    We examined the analgesic effect of nasal salmon calcitonin in patients with acute pain due to recent, nontraumatic osteoporotic vertebral crush fractures. 32 men and 68 postmenopausal women were studied using a prospective, double-blind, placebo-controlled clinical design. Men and women taking 200 IU of nasal salmon calcitonin daily for a period of 28 days had a dramatic decrease of spinal pain. This analgesic effect was accompanied by early mobilization and gradual restoration of the locomotor functions, such as sitting, standing and walking. Patients receiving the placebo nasal spray remained in bed for almost the entire period of observation. The consumption of high doses of paracetamol did not help placebo patients to get out of bed during the 4 weeks of hospitalization. Nasal salmon calcitonin and early mobilization also reduced hydroxyproline excretion, thus preventing massive bone loss during the period of bedrest. PMID:9385283

    2013-01-01

    Background Osteoporotic vertebral compression fracture is the leading cause of disability and morbidity in elderly people. Treatment of this condition remains a challenge. Osteoporotic vertebral compression fractures can be managed with various approaches, but each has limitations. In this study, we compared the clinical outcomes obtained using short-segment fixation with intravertebral expandable pillars (I-VEP) to those obtained with percutaneous kyphoplasty in patients who had suffered vertebral compression fractures. Methods The study included 46 patients with single-level osteoporotic thoracolumbar fractures. Twenty-two patients in Group I underwent short-segment fixation with I-VEP and 24 patients in Group II underwent kyphoplasty. All patients were evaluated pre- and postoperatively using a visual analogue scale, anterior height of the fractured vertebra, and kyphotic angle of the fractured vertebra. The latter 2 radiological parameters were measured at the adjacent segments as well. Results There was no significant difference between the groups in terms of gender or fracture level, but the mean age was greater in Group II patients (p = 0.008). At the 1-year follow-up, there were no significant differences in the visual analogue scale scores, anterior height of the fractured vertebra, or the value representing anterior height above the fractured vertebra and kyphotic angle below the fractured vertebra, after adjusting for the patients’ gender, fracture level, and age. When considered separately, the anterior height below the fractured vertebra was significantly higher and the kyphotic angle above the fractured vertebra was significantly smaller in Group I than in Group II (p = 0.029 and p = 0.008, respectively). The kyphotic angle of the fractured vertebra was significantly smaller in Group II than in Group I (p < 0.001). Conclusions In older individuals with vertebral compression fractures, kyphoplasty restored and maintained the collapsed vertebral body

    Background. The pathway for patients with a hip fracture described in this study is a fast track. Many studies have focused on prevention of various complications but, so far, the patient's view of nursing care has not been highlighted. Aim. The aim of the study is to illuminate the patient's view on nursing care when treated for a hip fracture. Method. Ten patients were interviewed. A content analysis design was conducted. Findings. From the analysis, four main categories emerged: waiting times; pain/pain relief and mobilisation; attitude/information and sense of security; complications. Conclusion. Patients generally felt satisfied with the nursing provided. The staff created a feeling of security and showed interest and empathy for the patient. However, patients experienced a stressful waiting for surgery, and patients who developed confusion waited more than 24 hours for surgery. Therefore, waiting time must be decreased. Furthermore, patients' descriptions of a variety of pain problem show, for example, that good collaboration between the nurse and physiotherapist is critical for achieving good pain relief before mobilisation. Nursing staff need to be attentive and should elicit the patient's feelings through patient-focused communication in order to relieve anxiety about going home. PMID:22811933

    Dynamic hip screw (DHS) is a well-established conventional implant for treating intertrochanteric fracture. However, revision surgery sometimes still occurs due to the cutting out of implants. A helical blade instead of threaded screw (DHS blade) was designed to improve the fixation power of the osteoporotic intertrochanteric fracture. In this study, the biomechanical properties of DHS blade compared to the conventional DHS were evaluated using an unstable AO/OTA 31-A2 intertrochanteric fracture model. Fifty synthetic proximal femoral bone models with such configuration were fixed with DHS and DHS blade in five different positions: centre-centre (CC), superior-centre (SC), inferior-center (IC), centre-anterior (CA), and centre-posterior (CP). All models had undergone mechanical compression test, and the vertical and rotational displacements were recorded. The results showed that DHS blade had less vertical or rotational displacement than the conventional DHS in CC, CA, and IC positions. The greatest vertical and rotational displacements were found at CP position in both groups. Overall speaking, DHS blade was superior in resisting vertical or rotational displacement in comparison to conventional DHS, and the centre-posterior position had the poorest performance in both groups.

    Vertebral compression fractures cause pain, deformity, and disability. Polypropylene fumarate (PPF) has shown promise as an injectable cement for bone defects but little is known about its performance for kyphoplasty. The purpose of this study was to evaluate the biomechanical performance of PPF for kyphoplasty in simulated anterior compression fractures in cadaveric vertebral bodies. Thirty-one vertebral bodies (T9 to L4) from osteoporotic cadaveric spines were disarticulated, stripped of soft tissue and compressed on a materials testing machine to determine pretreatment strength and stiffness. All fractures were repaired with inflatable balloon tamps and either polymethylmethacrylate or PPF-30 (containing 30% barium sulfate by dry weight) cement and then retested. Strength restoration with PMMA and PPF-30 were 120% and 104%, respectively, of the pretreatment strengths. For stiffness, PMMA and PPF-30 restored vertebral bodies to 69% and 53%, respectively, of the initial values. There was no significant difference in treatment with either PMMA or PPF-30. The biopolymer PPF-30 exhibits mechanical properties similar to PMMA in a cadaveric kyphoplasty model. PPF biopolymer may be a suitable alternative for kyphoplasty. PMID:18046174

    2012-01-01

    Background Few epidemiological data on hip fractures were previously available in Lithuania. The aim of this study was to estimate the incidence and hospital costs of hip fractures in Vilnius in 2010. Methods Data were collected from the medical charts of all patients admitted to hospitals in Vilnius (population, 548,835) due to new low-energy trauma hip fracture, during 2010. The estimated costs included ambulance transportation and continuous hospitalisation immediately after a fracture, which are covered by the Lithuanian healthcare system. Results The incidence of new low-energy trauma hip fractures was 252 (308 women and 160 men) per 100,000 inhabitants of Vilnius aged 50-years or more. There was an exponential increase in the incidence with increasing age. The overall estimated cost of hip fractures in Vilnius was 1,114,292 EUR for the year 2010. The greatest part of the expenditure was accounted for by fractures in individuals aged 65-years and over. The mean cost per case was 2,526.74 EUR, and cost varied depending on the treatment type. Hip replacement did not affect the overall mean costs of hip fracture. The majority of costs were incurred for acute (53%) and long-term care (35%) hospital stays, while medical rehabilitation accounted for only 12% of the overall cost. The costs of hip fracture were somewhat lower than those found in other European countries. Conclusion The data on incidence and costs of hip fractures will help to assess the importance of interventions to reduce the number of fractures and associated costs. PMID:22747915

    Purpose We aimed to evaluate the results of surgical treatment of periprosthetic femoral fractures in cementless total hip arthroplasty (THA). Materials and Methods From June 2002 to May 2012, 40 patients who could be followed-up for more than 1 year after surgery were enrolled in this study. The mean duration of follow-up was 28.5 months (range, 15-97 months) and the average age at the time of surgery was 71.5 years (range, 38-89 years). The fracture types were determined by using the Vancouver classification. Among intraoperative fractures, there were type A in 3 hips, type B2 in 2 hips and type B3 in one. Among postoperative fractures, type AG was present in 5 hips, type AL in 2 hips, type B1 in 15 hips, type B2 in 6 hips, type B3 in 3 hips, and type C in 3 hips. Evaluation of the results was based on bony union, stability of the prosthesis, postoperative complications, and Harris hip score at the final follow-up. Results Bony union was achieved in all but one case and the average time for bony union was 21 weeks. The mean Harris hip score was 86 at the final follow-up. Clinical results were above good in 34 of 40 hips (85.0%). Stem loosening occurred in one patient with a type B1 fracture treated with open reduction and plate fixation. Nonunion was observed in 1 patient with an AG type fracture. Conclusion Open reduction and fixation using a plate with a screw and cerclage wiring provided good results for periprosthetic fractures in patients who had a stable femoral stem without bone defects. Revision surgery with a cementless long stem should be considered in patients with an unstable stem or suspected stability in B1 type of THA using a proximal fixation type. PMID:27536618

  13. The effect of latitude on the risk and seasonal variation in hip fracture in Sweden.

    Although the optimal requirement of vitamin D for skeletal health in the general community is controversial, vitamin D deficiency impairs bone mineralization and increases bone turnover via secondary hyperparathyroidism, thus accelerating bone loss and increasing fracture risk. Support for a role of vitamin D deficiency in the epidemiology of hip fracture is found in the seasonal variation of hip fracture incidence that is reported in several studies. If the association were causal, then the incidence and amplitude of the seasonal variation in hip fracture risk should vary by latitude. We addressed this hypothesis by examining the incidence of hip fracture in men and women aged 50 years or more from Sweden (latitudes 55 to 69°) between 1987 and 2009. In order to reduce double counting, only one fracture in a period of a year was counted per individual. Men contributed 104,888 fractures in 33,313,065 person years and women 264,362 fractures in 38,387,660 person years. The effects of season and latitude were examined by Poisson regression. As expected, hip fracture rates were higher in women than in men. After adjustment for age, season and population density, hip fracture incidence increased by 3.0% (95% CI: 2.7-3.2%) per degree increase in latitude for men and by 1.9% (95% CI: 1.8-2.1%) for women. There was a marked seasonal variation of hip fracture with the highest risk in February and lower by 37.5% in men and by 23.5% women during the summer. There were significant interactions of amplitude of the seasonal variation with latitude (p < 0.001 for both men and women), indicating that seasonal variation during the year was more pronounced in the north of Sweden than in the south. The associations found with latitude and season is consistent with a role of vitamin D in hip fracture causation. PMID:24715585

    Introduction: Posterior dislocation of the hip joint with associated acetabular and intertrochanteric fracture is a complex injury. Early recognition, prompt and stable reduction is needed of successful outcome. Case Report: 45 year old male patient presented with posterior dislocation of the hip with transverse fracture with posterior wall fracture of acetabulam and intertrochanteric fracture on the ipsilateral side. The complex fracture geometry was confirmed by CT scan. The patient was successfully managed by open reduction and internal fixation of intertrochanteric fracture was achieved with dynamic hip screw (DHS) plate fixation followed by fixation of acetabular fracture with reconstruction plate. Conclusion: Hip dislocation combined with acetabular fracture is an uncommon injury; this article presents a unique case of posterior wall and transverse fractures of ipsilateral acetabulum with intertrochanteric fracture in a patient who sustained traumatic posterior hip dislocation. Early surgical intervention is important for satisfactory outcomes of such complex fracture-dislocation injuries. PMID:27298928

    Objectives to examine the impact of varied operational definitions for identifying hip fracture hospitalizations in administrative claims data. Design retrospective examination of Medicare inpatient and outpatient claims data. Setting nursing home population. Participants Medicaid- and Medicare-eligible nursing home residents in 1999 in CA, FL, MO, NJ, and PA (n=197,514). Measurements number of hip fractures identified in using inpatient (Medicare A) diagnoses codes, subjected to definitions varying according to whether or not hip fracture was required to be the principal diagnosis and whether or not confirmatory imaging and procedure codes were identified in other (Medicare B) claims files. Results Hip fractures were found in any inpatient diagnosis position in 4,680 subjects, with 4,479 of these found in the principal diagnosis position. With either approach to diagnosis position, confirmatory imaging and procedure codes were identified for 95% of persons hospitalized with hip fracture. Conclusion The principal diagnosis alone will identify 96% of hip fracture diagnoses in hospitalized nursing home residents. Such diagnoses are confirmed at very high rates by other sources of claims data. Researchers may be confident using a simple approach to identifying hip fracture hospitalizations in this population, using inpatient claims alone and interrogating only the principal diagnosis position.

    The purposes of this study were to develop a Social Cognitive Theory-based, structured Hip Fracture Prevention Web site for older adults and conduct a preliminary evaluation of its effectiveness. The Theory-based, structured Hip Fracture Prevention Web site is composed of learning modules and a moderated discussion board. A total of 245 older adults recruited from two Web sites and a newspaper advertisement were randomized into the Theory-based, structured Hip Fracture Prevention Web site and the conventional Web sites groups. Outcomes included (1) knowledge (hip fractures and osteoporosis), (2) self-efficacy and outcome expectations, and (3) calcium intake and exercise and were assessed at baseline, end of treatment (2 weeks), and follow-up (3 months). Both groups showed significant improvement in most outcomes. For calcium intake, only the Theory-based, structured Hip Fracture Prevention Web site group showed improvement. None of the group and time interactions were significant. The Theory-based, structured Hip Fracture Prevention Web site group, however, was more satisfied with the intervention. The discussion board usage was significantly correlated with outcome gains. Despite several limitations, the findings showed some preliminary effectiveness of Web-based health interventions for older adults and the use of a Theory-based, structured Hip Fracture Prevention Web site as a sustainable Web structure for online health behavior change interventions.

  17. A Biomechanical Approach to Assessing Hip Fracture Risk

    Bone loss in microgravity is well documented, but it is difficult to quantify how declines in bone mineral density (BMD) contribute to an astronaut's overall risk of fracture upon return. This study uses a biomechanical approach to assessing hip fracture risk, or Factor of Risk (Phi), which is defined as the ratio of applied load to bone strength. All long-duration NASA astronauts from Expeditions 1-18 were included in this study (n=25), while crewmembers who flew twice (n=2) were treated as separate subjects. Bone strength was estimated based on an empirical relationship between areal BMD at the hip, as measured by DXA, and failure load, as determined by mechanical testing of cadaver femora. Fall load during a sideways fall was calculated from a previously developed biomechanical model, which takes into account body weight, height, gender, and soft tissue thickness overlying the lateral aspect of the hip that serves to attenuate the impact force. While no statistical analyses have been performed yet, preliminary results show that males in this population have a higher FOR than females, with a post- flight Phi of 0.87 and 0.36, respectively. FOR increases 5.1% from preflight to postflight, while only one subject crossed the fracture "threshold" of Phi = 1, for a total of 2 subjects with a postflight Phi > 1. These results suggest that men may be at greater risk for hip fracture due largely in part to their relatively thin soft tissue padding as compared to women, since soft tissue thickness has the highest correlation (R(exp 2)= .53) with FOR of all subject-specific parameters. Future work will investigate changes in FOR during recovery to see if baseline risk levels are restored upon return to 1-g activity. While dual x-ray absorptiometry (DXA) is the most commonly used clinical measure of bone health, it fails to provide compartment-specific information that is useful in assessing changes to bone quality as a result of microgravity exposure.

    The purpose of this study was to test the reliability and validity of the Self-Efficacy for Exercise (SEE) and the Outcome Expectations for Exercise (OEE) scales in a sample of 166 older women post-hip fracture. There was some evidence of validity of the SEE and OEE based on confirmatory factor analysis and Rasch model testing, criterion based and convergent validity, and evidence of internal consistency based on alpha coefficients and separation indices and reliability based on R2 estimates. Rasch model testing demonstrated that some items had high variability. Based on these findings suggestions are made for how items could be revised and the scales improved for future use.

    Hip femur is extremely common in the elderly and is one of the most common reasons for admission in trauma care. The main reported causes of death after hip fracture were cardiovascular (29%), neurological (20%) and pulmonary. Large epidemiological studies have shown a relatively small decrease in mortality for 20 years despite an active approach to medical and surgical management. Yet 57% of deaths occurring within 30 days post-surgery are preventable because they are not related to a pre-existing disease. Preoperative management to optimize these patients could help to reduce morbidity and mortality and is thus a crucial issue. The anesthesia consultation is used to evaluate the perioperative risk, treat pain, manage treatment and stabilize the patient. An operative delay of more than 48hours after admission increases mortality. This period should not be prolonged by unnecessary investigations that will not change the perioperative management. The preoperative period is a key moment because it allows to choose the anesthetic technique. Even if this choice is controversial, continuous spinal anesthesia (titrated) do not modify the cardiovascular and neurological physiological balance of these precarious patients. PMID:21945704

    Study Design A biomechanical and radiographic study using vertebral analogues. Objectives Kyphoplasty and vertebroplasty are widely used techniques to alleviate pain in fractures secondary to osteoporosis. However, cement leakage toward vital structures like the spinal cord can be a major source of morbidity and even mortality. We define safe cement injection as the volume of the cement injected into a vertebra before the cement leakage occurs. Our objective is to compare the amount of cement that can be safely injected into an osteoporotic vertebra with simulated compression fracture using either vertebroplasty or balloon kyphoplasty techniques. Methods Forty artificial vertebral analogues made of polyurethane with osteoporotic cancellous matrix representing the L3 vertebrae were used for this study and were divided into four groups of 10 vertebrae each. The four groups tested were: low-viscosity cement injected using vertebroplasty, high-viscosity cement injected using vertebroplasty, low-viscosity cement injected using balloon kyphoplasty, and high-viscosity cement injected using balloon kyphoplasty. The procedures were performed under fluoroscopic guidance. The injection was stopped when the cement started protruding from the created vascular channel in the osteoporotic vertebral fracture model. The main outcome measured was the volume of the cement injected safely into a vertebra before leakage through the posterior vascular channel. Results The highest volume of the cement injected was in the vertebroplasty group using high-viscosity cement, which was almost twice the injected volume in the other three groups. One-way analysis of variance comparing the four groups showed a statistically significant difference (p < 0.005). Conclusions High-viscosity cement injected using vertebroplasty delivers more cement volume before cement leakage and fills the vertebral body more uniformly when compared with balloon kyphoplasty in osteoporotic vertebrae with

    Following the implementation of a long-term care insurance system for the elderly in Korea, many nursing homes have been established and many more patients than ever before have been living at nursing homes. Despite the fact that this is a high-risk group vulnerable to hip fractures, no study has yet been conducted in Korea on hip fracture incidence rates and prognoses among patients residing at nursing homes. We recently studied 46 cases of hip fracture in nursing homes; more specifically, we investigated the most common conditions under which fractures occur, and examined the degree of recovery of ambulatory ability and the mortality within 1 yr. Among those who had survived after 1 yr, the number of non-functional ambulators increased from 8 hips before hip fracture to 19 hips at final post-fracture follow-up. These individuals showed poor recovery of ambulatory ability, and the number who died within one year was 11 (23.9%), a rate not significantly different from that among community-dwelling individuals. It was evident that hip-joint-fracture nursing home residents survived for similar periods of time as did those dwelling in the community, though under much more uncomfortable conditions. The main highlight of this report is that it is the first from Korea on nursing home residents' ambulatory recovery and one-year mortality after hip fracture. The authors believe that, beginning with the present study, the government should collect and evaluate the number of hips fractured at nursing facilities in order to formulate criteria that will help to enable all patients to select safer and better-quality nursing facilities for themselves or their family members.

    Hip fracture is a major cause of morbidity, mortality and loss of independence for the elderly. Surgical fixation of the fractured hip remains the standard of care to allow for early mobilisation and a return to independence. Operative management in this population carries its own set of problems. The altered physiological state of the older person, often coupled with significant comorbidity, can present challenges for the anaesthetist, the surgeon and the rest of the perioperative team. This article provides an evidence-based review of the important perioperative factors associated with hip fractures in the older person and their management. PMID:21823308

    Purpose Volar plating for distal radius fractures has caused extensor tendon ruptures secondary to dorsal screw prominence. This study was designed to determine the biomechanical impact of placing unicortical distal locking screws and pegs in an extra-articular fracture model. Methods Volar-locking distal radius plates were applied to 30 osteoporotic distal radius models. Radii were divided into 5 groups based on distal locking fixation: bicortical locked screws, 3 lengths of unicortical locked screws (abutting the dorsal cortex [full length], 75% length, and 50% length to dorsal cortex), and unicortical locked pegs. Distal radius osteotomy simulated a dorsally comminuted, extra-articular, fracture. Each constructs stiffness was determined under physiologic loads (axial compression, dorsal bending volar bending) before and after 1000 cycles of axial conditioning and prior to axial loading to failure (2mm of displacement) and subsequent catastrophic failure. Results Cyclic conditioning did not alter constructs stiffness. Stiffness to volar bending and dorsal bending forces were similar between groups. Final stiffness(N/mm) under axial load was statistically equivalent for all groups: bicortical screws(230), full-length unicortical screws(227), 75% length unicortical screws(226), 50% length unicortical screws(187), unicortical pegs(226). Force(N) at 2 mm displacement was significantly less for 50% length unicortical screws(311) compared to bicortical screws(460), full-length unicortical screws(464), 75% length unicortical screws(400), and unicortical pegs(356). Force(N) to catastrophic fracture was statistically equivalent between groups but mean values for pegs(749) and 50% length unicortical(702) screws were 16-21% less than means for bicortical(892), full-length unicortical(860), and 75% length(894) unicortical constructs. Discussion Locked unicortical distal screws of at least 75% length produce construct stiffness similar to bicortical fixation. Unicortical

    Introduction. Incidence of Exeter stem fracture is extremely uncommon. Pubic rami insufficiency fractures following arthroplasty are also rare. To our knowledge no cases of spontaneous stem failure with previous insufficiency fractures have yet been reported. Case Presentation. This report describes a case of spontaneous fracture through a cemented Exeter stem in a 66-year-old patient who had previously undergone a hybrid total hip replacement and was found to have bifocal pubic rami insufficiency fractures. The patient presented 18-year postprimary surgery with spontaneous fracture of the middle third of the cemented femoral stem and adjacent proximal femur. Conclusion. This report demonstrates a unique case of Exeter stem fracture with previous pelvic insufficiency fractures. The case adds to the rare occurrences of Exeter stem failure in the literature and highlights the risk of potential insufficiency fractures in patients undergoing total hip replacement.

    Popularly known as "the silent disease" since early symptoms are usually absent, osteoporosis causes progressive bone loss, which renders the bones susceptible to fractures. Bone fracture healing is a complex process consisting of four overlapping phases-hematoma formation, inflammation, repair, and remodeling. The traditional use of natural products in bone fractures means that phytochemicals can be developed as potential therapy for reducing fracture healing period. Located closely near the equator, Malaysia has one of the world's largest rainforests, which are homes to exotic herbs and medicinal plants. Eurycoma longifolia (Tongkat Ali), Labisia pumila (Kacip Fatimah), and Piper sarmentosum (Kaduk) are some examples of the popular ethnic herbs, which have been used in the Malay traditional medicine. This paper focuses on the use of natural products for treating fracture as a result of osteoporosis and expediting its healing. PMID:22973405

This treatment induces osseous structural and compositional changes accompanied by positive effects on osteoblasts and osteocytes. Here, we test the hypothesis that restored osseous cell behavior, which resembles characteristics of younger, healthy cortical bone, leads to improved bone quality. Microarchitecture and mechanical properties of young, treatment-naïve osteoporosis, and bisphosphonate-treated cases were investigated in femoral cortices. Tissue strength was measured using three-point bending. Collagen fibril-level deformation was assessed in non-traumatic and traumatic fracture states using synchrotron small-angle x-ray scattering (SAXS) at low and high strain rates.

    Purpose. To evaluate relationships between biochemical markers of bone turnover, bone mineral density, and new compression fractures following vertebroplasty. Methods. Initially, we enrolled 30 consecutive patients with vertebral compression fractures caused by osteoporosis. Twenty-three of the 30 patients visited our hospital for follow-up examinations for more than 4 weeks after vertebroplasty. The patients were divided into two groups: patients with new fractures (group F) and patients with no new fractures (group N). We analyzed differences in the following parameters between these two groups: serum bone alkaline phosphatase, urinary crosslinked N-telopeptide of type I collagen, urinary deoxypyridinoline, and bone mineral density. Next, the patients were divided into another two groups: patients with higher risk (group H: urinary crosslinked N-telopeptide of type I collagen >54.3 nmol BCE/mmol Cr or urinary deoxypyridinoline >7.6 nmol/mmol Cr, and serum bone alkaline phosphatase <29.0 U/l) and patients with lower risk (group L). We analyzed the difference in the rate of new fractures between these two groups. Results. We identified 9 new fractures in 7 patients. There were no significant differences between groups F and N. We identified 5 new fractures in 3 of the 4 patients in group H, and 4 new fractures in 4 of the 19 patients in group L. There was a significant difference in the rate of new fractures between groups H and L. Conclusions. A combination of high levels of bone resorption markers and normal levels of bone formation markers may be associated with increased risk of new recurrent fractures after percutaneous vertebroplasty.

    Background Cervical fractures from falls are a potentially lethal injury in older patients. Little is known about their epidemiology and outcomes. Objectives To examine the prevalence of cervical spine fractures after falls among older Americans and show changes in recent years. Further, to compare 12-month outcomes in patients with cervical and hip fracture after falls. Design, Setting, and Participants A retrospective study of Medicare data from 2007–2011 including patients ≥65 with cervical fracture and hip fracture after falls treated at acute care hospitals. Measurements Rates of cervical fracture, 12-month mortality and readmission rates after injury. Results Rates of cervical fracture increased from 4.6/10,000 in 2007 to 5.3/10,000 in 2011, whereas rates of hip fracture decreased from 77.3/10,000 in 2007 to 63.5/10,000 in 2011. Patients with cervical fracture without and with spinal cord injury (SCI) were more likely than patients with hip fracture, respectively, to receive treatment at large hospitals (54.1%, 59.4% vs. 28.1%, p< 0.001), teaching hospitals (40.0%, 49.3% vs. 13.4%, p< 0.001), and regional trauma centers (38.5%, 46.3% vs. 13.0%, p< 0.001). Patients with cervical fracture, particularly those with SCI, had higher risk-adjusted mortality rates at one year than those with hip fracture (24.5%, 41.7% vs. 22.7%, p<0.001). By one year, more than half of patients with cervical and hip fracture died or were readmitted to the hospital (59.5%, 73.4% vs. 59.3%, p<0.001). Conclusion Cervical spine fractures occur in one of every 2,000 Medicare beneficiaries annually and appear to be increasing over time. Patients with cervical fractures had higher mortality than those with hip fractures. Given the increasing prevalence and the poor outcomes of this population, hospitals need to develop processes to improve care for these vulnerable patients. PMID:26456855

    Femoral neck fractures in the elderly are a common problem in orthopedics. Augmentation of screw fixation with bone cement can provide better stability of implants and lower the risk of secondary displacement. This study aimed to investigate whether cement augmentation of three cannulated screws in non-displaced femoral neck fractures could increase implant fixation. A femoral neck fracture was simulated in six paired human cadaveric femora and stabilized with three 7.3 mm cannulated screws. Pairs were divided into two groups: conventional instrumentation versus additional cement augmentation of screw tips with 2 ml TraumacemV+ each. Biomechanical testing was performed by applying cyclic axial load until failure. Failure cycles, axial head displacement, screw angle changes, telescoping and screw cut-out were evaluated. Failure (15 mm actuator displacement) occurred in the augmented group at 12,500 cycles (± 2,480) compared to 15,625 cycles (± 4,215) in the non-augmented group (p = 0.041). When comparing 3 mm vertical displacement of the head no significant difference (p = 0.72) was detected between the survival curves of the two groups. At 8,500 load-cycles (early onset failure) the augmented group demonstrated a change in screw angle of 2.85° (± 0.84) compared to 1.15° (± 0.93) in the non-augmented group (p = 0.013). The results showed no biomechanical advantage with respect to secondary displacement following augmentation of three cannulated screws in a non-displaced femoral neck fracture. Consequently, the indication for cement augmentation to enhance implant anchorage in osteoporotic bone has to be considered carefully taking into account fracture type, implant selection and biomechanical surrounding.

    Low-magnitude high-frequency vibration (LMHFV) has been proven to promote osteoporotic fracture healing. Mechanical stimulation was reported to enhance SDF-1/CXCR4 signalling in mesenchymal stem cells (MSCs). We hypothesised that LMHFV promoted osteoporotic fracture healing by enhancing MSC migration through the SDF-1/CXCR4 pathway. 152 ovariectomised SD-rats received closed femoral fracture in groups of vibration+MSC (VMG) (20 min/d, 5 d/week), vibration+MSC+AMD3100 (VMAG; AMD, a CXCR4 inhibitor) (1 mg/kg/d, intraperitoneal), MSC (MG) (1 × 106 MSC, intracardiac) or control (CG) for a treatment duration of 2, 4 or 8 weeks. MSC migration was evaluated by ex-vivo green fluorescent protein signal in the callus; and fracture healing was examined by weekly radiographs, endpoint computed-tomography and mechanical test. At week-2 and week-4, ex-vivo callus GFP intensity of VMG was significantly higher than other groups (p < 0.05). From week-2 to week-3, both callus width and callus area in VMG were significantly larger; and from week-7 to week-8, smaller than other groups (p < 0.05). At week-8, high-density bone volume fraction, bone volume fraction, bone mineral density and stiffness in VMG were significantly higher than other 3 groups (p < 0.05). This study demonstrated that LMHFV promoted MSC migration and fracture healing in osteoporotic rats. This effect was attenuated by CXCR4 inhibitor, providing strong evidence that SDF-1-mediated MSC migration was one of the important mechanisms through which LMHFV enhanced fracture healing.

    Abstract Background There are several potential risk factors in patients with a hip fracture for a higher rate of mortality that include: comorbid disorders, poor general health, age, male gender, poor mobility prior to injury, type of fracture, poor cognitive status, place of residence. The aim of this study was to assess the influence of potential risk factors for six-month mortality in hip fracture patients. Methods The study included all patients with a hip fracture older than 65 who had been admitted to the Clinic for orthopaedic surgery during one year. One hundred and ninety-two patients were included in the study. Results Six months after admission due to a hip fracture, 48 patients had died (6-month mortality rate was 25%). The deceased were statistically older than the patients who had survived. Univariate regression analysis indicated that six variables had a significant effect on hip fracture patients’ survival: age, mobility prior to the fracture, poor cognitive status, activity of daily living, comorbidities and the place where they had fallen. Multivariate regression modelling showed that the following factors were independently associated with mortality at 6 months post fracture: poor cognitive status, poor mobility prior to the fracture, comorbid disease. Conclusion Poor cognitive status appeared to be the strongest mortality predictor. The employment of brief tests for cognitive status evaluation would enable orthopaedists to have good criteria for the choice of treatment for each patient screened. PMID:27284379

    OBJECTIVE: To determine the current values and estimate the projected values (to the year 2041) for annual number of proximal femoral fractures (PFFs), age-adjusted rates of fracture, rates of death in the acute care setting, associated length of stay (LOS) in hospital, and seasonal variation by sex and age in elderly Canadians. DESIGN: Hospital discharge data for fiscal year 1993-94 from the Canadian Institute for Health Information were used to determine PFF incidence, and Statistics Canada population projections were used to estimate the rate and number of PFFs to 2041. SETTING: Canada. PARTICIPANTS: Canadian patients 65 years of age or older who underwent hip arthroplasty. OUTCOME MEASURES: PFF rates, death rates and LOS by age, sex and province. RESULTS: In 1993-94 the incidence of PFF increased exponentially with increasing age. The age-adjusted rates were 479 per 100,000 for women and 187 per 100,000 for men. The number of PFFs was estimated at 23,375 (17,823 in women and 5552 in men), with a projected increase to 88,124 in 2041. The rate of death during the acute care stay increased exponentially with increasing age. The death rates for men were twice those for women. In 1993-94 an estimated 1570 deaths occurred in the acute care setting, and 7000 deaths were projected for 2041. LOS in the acute care setting increased with advancing age, as did variability in LOS, which suggests a more heterogeneous case mix with advancing age. The LOS for 1993-94 and 2041 was estimated at 465,000 and 1.8 million patient-days respectively. Seasonal variability in the incidence of PFFs by sex was not significant. Significant season-province interactions were seen (p < 0.05); however, the differences in incidence were small (on the order of 2% to 3%) and were not considered to have a large effect on resource use in the acute care setting. CONCLUSIONS: On the assumption that current conditions contributing to hip fractures will remain constant, the number of PFFs will rise

    Objective To explore what patients consider important when evaluating their recovery from hip fracture and to consider how these priorities could be used in the evaluation of the quality of hip fracture services. Design Semistructured interviews exploring the experience of recovery from hip fracture at two time points—4 weeks and 4 months postoperative hip fixation. Two approaches to analysis: thematic analysis of data specifically related to recovery from hip fracture; summarising the participant's experience overall. Participants 31 participants were recruited, of whom 20 were women and 12 were cognitively impaired. Mean age was 81.5 years. Interviews were provided by 19 patients, 14 carers and 8 patient/carer dyad; 10 participants were interviewed twice. Setting Single major trauma centre in the West Midlands of the UK. Results Stable mobility (without falls or fear of falls) for valued activities was considered most important by participants who had some prefracture mobility and were able to articulate what they valued during recovery. Mobility was important for managing personal care, for day-to-day activities such as shopping and gardening, and for maintenance of mental well-being. Some participants used assistive mobility devices or adapted to their limitations. Others maintained their previous limited function through increased care provision. Many participants were unable to articulate what they valued as hip fracture was perceived as part of their decline with age. The fracture and problems from other health conditions were an inseparable part of one health experience. Conclusions Prefracture mobility, adaptations to reduced mobility before or after fracture, and whether or not patients perceive themselves to be declining with age influence what patients consider important during recovery from hip fracture. No single patient-reported outcome measure could evaluate quality of care for all patients following hip fracture. General health

    Incidence of hip fracture among patients with Alzheimer's disease (AD), especially in elderly patients, is high. To analyze risk factors of hip fracture, we prospectively studied a cohort of elderly female patients with AD. Subjects studied were 225 female patients with AD, and the average age was 76 years old. At baseline, we recorded body mass index (BMI), a score of Mini-Mental State Examination (MMSE) and bone mineral density (BMD), and measured serum concentrations of ionized calcium, intact parathyroid hormone (PTH), pyridinoline cross-linked carboxyterminal telopeptide of type I collagen (ICTP), intact bone Gla protein (BGP), 25-hydroxyvitamin (25-OHD) and 1, 25-dihydroxyvitamin D (1, 25-[OH]2D). The patients were followed for 2 years. During the 2-year study, hip fractures occurred in 29 patients. We compared baseline variables between the 29 patients with and 176 patients without hip fracture. AD patients with lower BMD, low concentrations of serum ionized calcium and 25-OHD (mean 3.0 ng/ml) with compensatory hyperparathyroidism were found to have an increased risk of hip fracture. Also, concentrations of serum ICTP and BGP were higher in the fracture group than in the nonfracture group. Elderly female AD patients with low BMD and serum 25-OHD concentrations <5 ng/ml with secondary hyperparathyroidism have a high risk of hip fracture, and the risk may be reduced by vitamin D supplementation.

    Purpose To investigate the clinical and radiologic outcomes following treatment of intertrochanteric fractures using the Compression Hip Nail® (CHN), which has a sliding lag screw. Materials and Methods Twenty-eight cases of intertrochanteric fractures treated with CHN from November 2012 to October 2013 and followed-up for >6 months were included. The patient population consisted of 11 men and 17 women with a mean age of 75.2 years at the time of surgery. For the initial 11 cases, 10 mm sliding lag screws were used; the remaining 17 cases used 20 mm sliding lag screws. Clinical variables including operation time, amount of transfusion, weight-bearing start time, postoperative physical activity, and complications were investigated. The average sliding of lag screws and the average union were investigated radiologically at 3 and 6 months after surgery. Results In an analysis of 23 cases (exclusion of 3 cases of lag screw cutout and 2 cases of nonunion), 11 (48%) recovered their pre-injury activity level. In an analysis of 25 cases (exclusion of 3 cases of cutout), 17 (68%) and 23 (92%) showed radiological union at postoperative months 3 and 6, respectively. Seven complications were noted. Cutout of the lag screw and the lateral protrusion of barrels were significantly greater in the group with 10 mm sliding lag screws as compared to the group using 20 mm sliding lag screws. Conclusion The use of CHN for the treatment of intertrochanteric fracture yielded poor results. However, results from patients in the 20 mm sliding lag screw group were better than for the 10 mm sliding lag screw group. Therefore, use of the 20 mm sliding lag screw is advisable.

    With an increased life expectancy in humans and thus an increase in the number of the elderly population, the frequency of hip fractures will rise as well. Aside from a higher incidence, hip fractures in a geriatric population is a significant problem due to the possible onset of severe and in some cases dramatic complications and consequences. The primary purpose of treatment and rehabilitation in the elderly after a hip fracture is to improve an individual’s quality of life. It is important to underline that principles and methods of functional restoration after hip fracture should consider careful planning of a rehabilitation program individually for every patient and its implementation with respect to decisions made by the rehabilitation team.

    Background It is debatable whether a managed care model would affect the quality of care and length of hospital stay in the treatment of hip fractures in elderly patients. Methods This prospective study was undertaken to determine whether or not a managed care critical pathway tool shortened hospital stay in a group of 102 senior patients with fractures of the hip during follow-up. We compared our study findings with two equivalent populations of senior hip fracture patients not treated using a critical care pathway concerning specific markers of quality. Results The managed care group had a 9% mortality rate, 95% return to prefracture living and 63% return to ambulatory status. The rates compared favorably with previous studies. The quality of care provided before and after the critical pathway was equivalent, while the post-pathway length of stay dropped 30%. Conclusions The proposed care protocol is recommended to shorten hospital stay in elderly patients with hip fractures. PMID:26929795

    As in many conditions, gender interplays with other social structures of inequality to impact upon women's and men's health and healthcare. This narrative review examines knowledge about sex, gender and hip fracture and suggests ways of highlighting the influence of gender in hip fracture healthcare. These will be considered in relation to two areas. Firstly the multifactorial dimension of hip fractures which identifies ethnicity, marital status, lifestyle, co-morbidities, environment in relation to falls and osteoporosis as important factors influencing the experience of hip fracture. Secondly the importance of acknowledging gender as a key element within research and management of care. Implications for practice are that we need a raised awareness of gender when we assess and care for patients, to ask critical questions about the gender bias in the evidence we use and reflect on how services and care practices may be biased towards gendered assumptions.

    Objective The objectives are to describe for the first time a home-based exercise intervention for frail elderly hip fracture patients and to describe the feasibility of this exercise program. Design A home-based exercise program was used in a randomized controlled trial in which the authors investigated exercise intervention versus no exercise intervention in patients after hip fracture. Setting This program was implemented at the patients’ own home or place of residence after discharge. Participants Women 65 years of age or older were recruited within 15 days of hip fracture. Eligible patients were those with a nonpathologic fracture who were admitted within 72 hours of injury, had surgical repair of the hip fracture, and met medical inclusion criteria. Participants initially were randomized to exercise groups and then assigned to exercise trainers. Intervention The exercise contained strength training and aerobic components. Participants were expected to exercise 5 days per week by performing a combination of supervised and independently performed exercise sessions. Intensity and duration were increased gradually by trainers in a standardized way. The frequency of the supervised sessions decreased as participants became more independent. Treatment fidelity visits ensured that the intervention was being delivered as intended across trainers and across participants. Main Outcome Measurement This work describes the feasibility and challenges of administering an intensive home-based exercise program in this population of older adults. Results Of those patients randomized to exercise, 82% were followed by a trainer and almost all advanced to higher levels in both aerobic and strength programs. Overall, participants received an average of 44 (78.5%) of the prescribed visits by the trainer. Conclusions This study showed that it was possible to engage a frail older population of post-hip fracture patients in a program of aerobic and strength training exercise with a

    The effect of a pulse dose of Vitamin D/sub 3/ on uptake of (/sup 99m/Tc)MDP by fractured and osteoporotic bone, respectively, was compared with D/sub 3/'s effect on uptake by normal bone in rats. At 4, 7, and 14 days, respectively, after femoral fracture, basal uptake was significantly increased at the fracture site by 336.8, 276.1, and 183.5%, respectively, over the contralateral control site. D/sub 3/-treated rats had lower uptakes than untreated controls at all three fracture sites and at 12 of 15 normal bone sites but analysis of variance showed the uptake differences were not significant. Cortisone-induced osteoporosis caused a significant decrease in basal uptake. The decrease occurred in all nine bone areas studied. D/sub 3/ caused a significant increase in uptake by these osteoporotic bones, but a significant decrease in uptake by the same bones in normal controls. Thus, D/sub 3/ had an effect on uptake by the bone lesion, osteoporosis, that differed from D/sub 3/'s effect on uptake by fracture or normal bone.

    The authors prospectively explored the consequences of hip fracture with regard to discharge placement, functional status, and mortality using the Survey on Assets and Health Dynamics Among the Oldest Old (AHEAD). Data from baseline (1993) AHEAD interviews and biennial follow-up interviews were linked to Medicare claims data from 1993–2005. There were 495 postbaseline hip fractures among 5,511 respondents aged ≥69 years. Mean age at hip fracture was 85 years; 73% of fracture patients were white women, 45% had pertrochanteric fractures, and 55% underwent surgical pinning. Most patients (58%) were discharged to a nursing facility, with 14% being discharged to their homes. In-hospital, 6-month, and 1-year mortality were 2.7%, 19%, and 26%, respectively. Declines in functional-status-scale scores ranged from 29% on the fine motor skills scale to 56% on the mobility index. Mean scale score declines were 1.9 for activities of daily living, 1.7 for instrumental activities of daily living, and 2.2 for depressive symptoms; scores on mobility, large muscle, gross motor, and cognitive status scales worsened by 2.3, 1.6, 2.2, and 2.5 points, respectively. Hip fracture characteristics, socioeconomic status, and year of fracture were significantly associated with discharge placement. Sex, age, dementia, and frailty were significantly associated with mortality. This is one of the few studies to prospectively capture these declines in functional status after hip fracture.

    Objective To evaluate whether an early bone marrow edema pattern predicts vertebral deformity types and prognosis in osteoporotic vertebral compression fracture (OVCF). Methods This retrospective study enrolled 64 patients with 75 acute OVCFs who underwent early MRI and followed up MRI. On early MRI, the low SI pattern of OVCF on T1WI were assessed and classified into 3 types (diffuse, globular or patchy, band-like). On followed up MRI, the vertebral deformity types (anterior wedge, biconcave, crush), degree of vertebral body height loss, incidence of vertebral osteonecrosis and spinal stenosis were assessed for each vertebral fracture types. Results According to the early bone marrow edema pattern on T1WI, 26 vertebrae were type 1, 14 vertebrae were type 2 and 35 vertebrae were type 3. On followed up MRI, the crush-type vertebral deformity was most frequent among the type 1 OVCFs, the biconcave-type vertebral deformity was most frequent among the type 2 OVCFs and the anterior wedge-type vertebral deformity was most frequent among the type 3 OVCFs (p<0.001). In addition, type 1 early bone marrow edema pattern of OVCF on T1WI were associated with higher incidence of severe degree vertebral body height loss, vertebral osteonecrosis and spinal stenosis on the follow up MRI. Conclusion Early bone marrow edema pattern of OVCF on T1WI, significant correlated with vertebral deformity types on the follow up MRI. The severe degree of vertebral height loss, vertebral osteonecrosis, and spinal stenosis were more frequent in patients with diffuse low SI pattern. PMID:26962419

    Using a social ecological model, this paper describes selected intra- and interpersonal factors that influence exercise behavior in women post hip fracture who participated in the Exercise Plus Program. Model testing of factors that influence exercise behavior at 2, 6 and 12 months post hip fracture was done. The full model hypothesized that demographic variables; cognitive, affective, physical and functional status; pain; fear of falling; social support for exercise, and exposure to the Exercise Plus Program would influence self-efficacy, outcome expectations, and stage of change both directly and indirectly influencing total time spent exercising. Two hundred and nine female hip fracture patients (age 81.0 ± 6.9), the majority of whom were Caucasian (97%), participated in this study. The three predictive models tested across the 12 month recovery trajectory suggest that somewhat different factors may influence exercise over the recovery period and the models explained 8 to 21% of the variance in time spent exercising. To optimize exercise activity post hip fracture, older adults should be helped to realistically assess their self-efficacy and outcome expectations related to exercise, health care providers and friends/peers should be encouraged to reinforce the positive benefits of exercise post hip fracture, and fear of falling should be addressed throughout the entire hip fracture recovery trajectory.

    Summary Research has not examined changes in bone mineral density (BMD) between men and women following hip fracture. The aim was to evaluate sex differences in BMD following hip fracture. Men experienced significant declines in BMD, while not statistically greater than women, underscoring the necessity for better osteoporosis care in men. Introduction Each year in the USA, approximately 260,000 older adults experience a hip fracture. Women experiencing hip fracture have excess decline in BMD in the year following fracture compared to expected decrements due to aging, but few studies have assessed sex differences in the sequelae of hip fracture. Thus, our objective was to examine sex differences in BMD change in the year after hip fracture. Methods The sample (n = 286) included persons enrolled in the Baltimore Hip Studies 7th cohort, a study that matched (1:1) men and women experiencing hip fracture. Weighted estimating equations that accounted for missing data and selective survival were used to estimate sex differences in 12-month total hip (TH) and femoral neck (FN) BMD changes. Results Men had larger average adjusted percent decline in TH and FN BMD. Adjusted 12-month decreases at the FN showed a statistically significant decline of −4.60 % (95 % confidence interval [CI] −7.76 %, −0.20 %) in men and an insignificant change of-1.62 % (95 % CI −4.57 %, 1.32 %) in women. Yet, the difference in change between men and women was not statistically significant (P = 0.17). The estimated sex differences for TH BMD loss were smaller in magnitude. Conclusions There is evidence of significant BMD loss among men at the FN in the year after hip fracture. Although not statistically greater than women, these clinically significant findings highlight the need for improved osteoporosis care among men prior to and after hip fracture. PMID:26847627

    Mokhtarzadeh, Hossein; Anderson, Dennis E

    2016-06-01

    This review examines the current evidence for associations between vertebral fractures (VFx), the most common type of fracture in older adults, and trunk muscles, which are intimately tied to spinal loading and function. Individuals with prevalent VFxs have more fat infiltration in the trunk muscles, lower trunk extension strength, and altered muscle activation patterns. However, no longitudinal studies have examined whether assessment of trunk muscle can contribute to prediction of fracture risk. A few studies report that exercise interventions targeting the trunk muscles can reduce the risk of VFx, improve trunk strength and endurance in patients who have had a VFx, and reduce the risk of falling, a common cause of VFx, but the quality of evidence is low. Trunk muscles likely have an important role to play in prediction, prevention, and management of VFx, but additional longitudinal studies and randomized controlled trials are needed to clarify this role.

    As the geriatric population in the United States continues to increase, ankle fractures in the elderly are predicted to exponentially increase in the future. As such, these injuries will become a common injury seen by physicians in various fields. Currently, no studies discussing low-energy open ankle fractures in the elderly and/or the mortality rate associated with these devastating injuries have been published. The purpose of the present study was to retrospectively review the morality rate associated with low-energy open ankle fractures in the elderly. We retrospectively identified 11 patients >60 years old who had sustained low-energy open ankle fractures and been treated at our institution. The patient demographics, mechanism of injury, wound size, medical comorbidities, treatment, follow-up data, and outcomes were recorded. Low-energy falls were defined as ground level falls from sitting or standing. The mean age of the patients was 70.72 years, with a mean body mass index of 35.93 ± 10.24. Of the 11 patients, 9 (81.81%) had ≥3 comorbidities (i.e., hypertension, diabetes, coronary artery disease, congestive heart failure, and/or chronic obstructive pulmonary disease). The mean size of the medially based ankle wound was 14.18 ± 4.12 cm; 10 (90.90%) were Gustilo and Anderson grade IIIA open ankle fractures. In our study, low-energy open ankle fractures in the elderly, very similar to hip fractures, were associated with a high mortality incidence (27.27%) at a mean of 2.67 ± 2.02 months, and 81.81% of our patients had ≥3 medical comorbidities.

    Purpose Although the incidence of a second hip fracture is relatively well described, mortality and morbidity after a second hip fracture are seldom evaluated. The purpose of this study was to determine the incidence, morbidity, and mid-term mortality of a second hip fracture and evaluate the cause of death after a second hip fracture. Materials and Methods Information on patients older than 50 years, who sustained a subsequent hip fracture, were obtained from the records of eight Jeju Island hospitals between 2002 and 2011 to calculate the incidence, morbidity, and mortality of hip fractures in this age group. All patients were followed a minimum of 2 years. A systemic search for death certificates at the National Statistical Office was conducted for patients who were lost to follow-up. Results Of 2,055 hip fractures (419 men and 1,636 women), 98 were second hip fractures (13 men and 85 women) during the study period. The mean ages of the patients at the time of the first and second fractures were 78.8 and 80.8 years, respectively. The incidence of a subsequent hip fracture among the first hip fracture was 4.8%. Mean mortality rates at 6 months, 1 year, 2 years, and 5 years were 10.5%, 15.2%, 23.5%, and 42.0% respectively. Cumulative mortality after the second hip fracture at the 5 years follow-up was 41.8%. Conclusion Our results demonstrate that a secondary fracture prevention program is necessary to prevent second hip fractures in elderly patients.

    Patients with MRI-proved acute painful vertebral fractures in whom conservative pain management fails are frequently referred for vertebroplasty. This study investigated the effects of treating osteoporosis on the mortality rate of patients with MRI-proved acute osteoporosis-related vertebral fractures who had undergone vertebroplasty. We retrospectively reviewed the cases of osteoporosis patients with MRI-proved acute vertebral fractures who had been treated with vertebroplasty from January 2001 to December 2007. The long-term outcomes of the patients who received antiosteoporotic therapy were compared with those of patients who received no therapy. A total of 304 patients (247 female patients and 57 male patients; mean age, 74.1 ± 7.7 years) were enrolled in the study. The patients who received antiosteoporotic therapy had a significantly lower mortality rate than did patients who did not receive antiosteoporotic therapy (P = 0.001; hazard ratio, 0.396, 95 % confidence interval, 0.273-0.575). At the end of the study, 183 patients were alive, and 121 had died. Effective treatment for osteoporosis may improve survival in patients with osteoporosis-related vertebral fractures after vertebroplasty. PMID:26040410

    This study aims to systematically review epidemiological studies that evaluate the relationship between meteorology and the incidence of hip fracture (HF). After a search in Scopus, PubMed, and Embase, two independent authors assessed the relevance of studies and extracted data for description. From each study, we extracted the geographic and temporal scope, design, study variables (meteorological and related to HF), statistical analysis, and estimated associations. Of a total of 134 works, 20 studies were selected. All use an ecological design but one case-crossover. Most studies have been conducted in northern latitudes. The analysis methodology did not take into account the temporal structure of the data in 10 studies (regression and linear correlations); the rest used Poisson regression (7) and ARIMA model (3). Most studies showed significant positive associations with rainfall, especially in the form of snow: HF relative risk (RR) on days with precipitation vs. days without precipitation that ranged from 1.14 (95 % confidence interval (CI)1.04 to 1.24) to 1.60 (95 % CI 1.06 to 2.41), the temperature, with RR by one degree Celsius decline from 1.012 (95 % CI 1.004 to 1.020) to 1.030 (95 % CI 1.023 to 1.037), and wind (3) RR FC windiest days vs. calm days: 1.32 (95 % CI 1.10 to 1.58) to 1.35 (95 % CI 0.88 to 2.08). This review shows that analytic methods are very heterogeneous and poorly adapted to the temporary nature of the data. Studies confirm a certain seasonality, with more fractures in winter and meaningful relationships with meteorological conditions typical of this season.

    2016-05-01

    Bone density insufficiency is the main cause for significant musculoskeletal trauma in the elderly population following low-energy falls. Hip fractures, in particular, represent an important public health concern taking into account the complicated needs of the patients due to their medical comorbidities as well as their rehabilitation and social demands. The annual cost for the care of these patients is estimated at around 2 billion pounds (£) in the UK and is ever growing. An increased early and late mortality rate is also recognised in these injuries together with significant adversities for the patients. Lately, in order to improve the outcomes of this special cohort of patients, fast-track care pathways and government initiatives have been implemented. It appears that these measures have contributed in a steady year-by-year reduction of the 30-day mortality rates. Whether we have currently reached a plateau or whether an ongoing reduction in mortality rates will continue to be observed is yet to be seen. PMID:26943870

    Nine-hundred twenty-one community-dwelling patients 65 years of age or older, who sustained an operatively treated hip fracture from July 1, 1987 to June 30, 1998 were followed up for the development of postoperative delirium. The outcomes examined in the current study were postoperative complication rates, in-hospital mortality, hospital length of stay, hospital discharge status, 1-year mortality rate, place of residence, recovery of ambulatory ability, and activities of daily living 1 year after surgery. Forty-seven (5.1%) patients were diagnosed with postoperative delirium. Patients who had delirium develop were more likely to be male, have a history of mild dementia, and have had surgery under general anesthesia. Patients who had postoperative delirium develop had a significantly longer length of hospitalization. They also had significantly higher rates of mortality at 1 year, were less likely to recover their prefracture level of ambulation, and were more likely to show a decline in level of independence in basic activities of daily living at the 1-year followup. There was no difference in the rate of postoperative complications, in-hospital mortality, discharge residence, and recovery of instrumental activities of daily living at 1 year. PMID:15187857

    Periprosthetic fractures of the femur in association with total hip arthroplasty are increasingly common and often difficult to treat. Patients with periprosthetic fractures are typically elderly and frail and have osteoporosis. No clear consensus exists regarding the optimal management strategy because there is limited high-quality research. The Vancouver classification facilitates treatment decisions. In the presence of a stable prosthesis (type-B1 and -C fractures), most authors recommend surgical stabilization of the fracture with plates, strut grafts, or a combination thereof. In up to 20% of apparent Vancouver type-B1 fractures, the femoral stem is loose, which may explain the high failure rates associated with open reduction and internal fixation. Some authors recommend routine opening and dislocation of the hip to perform an intraoperative stem stability test to rule out a loose component. Advances in plating techniques and technology are improving the outcomes for these fractures. For fractures around a loose femoral prosthesis (types B2 and 3), revision using an extensively porous-coated uncemented long stem, with or without additional fracture fixation, appears to offer the most reliable outcome. Cement-in-cement revision using a long-stem prosthesis is feasible in elderly patients with a well-fixed cement mantle. It is essential to treat the osteoporosis to help fracture healing and to prevent further fractures. We provide an overview of the causes, classification, and management of periprosthetic femoral fractures around a total hip arthroplasty based on the current best available evidence. PMID:23569704

    Introduction: The anterior dislocation of the hip represents only a small percentage of all hip dislocations: 85% are posterior. Most commonly associated with this dislocation is a fracture of the femoral head and, in rare cases, a femoral neck fracture. We have found in literature no report of an anterior dislocation of the hip associated with femoral neck fracture, pelvic retention of the head and ureteral fistula. We report such a case of a 68 year old male. Case Report: A 68 year old male was presented to our attention, following a severe injury of the hip when falling from a high bridge, with severe pain in the hip and a clinical aspect of femoral neck fracture. The X-ray confirmed the femoral neck fracture but following an anterior dislocation with the head retained into the pelvis. The patient also had hematuria. An Austin Moore prosthesis was implanted for the femoral neck fracture and the head was extracted by the urologist by a new abdominal incision. Urological evaluation revealed a fistula of the ureter, treated by an internal drainage for three months. One month later the Moore prosthesis was extracted and the patient had a Girldestone hip for 5 months. Revision with a Muller cemented prosthesis had a normal evolution. Conclusion: The anterior fracture dislocation of the hip with pelvic retention of the femoral head and ureteral fistula is a rare condition resulting from high energy trauma. A multidisciplinary team is necessary to diagnose and treat fracture and soft tissue lesions. Early diagnosis and treatment is necessary to avoid septic complications. PMID:27298980

    Morphometric methods have been developed for standardized assessment of vertebral deformities in clinical and epidemiologic studies of spinal osteoporosis. However, vertebral deformity may be caused by a variety of other conditions. To examine the validity of morphometrically assessed vertebral deformities as an index of osteoporotic vertebral fractures, we developed an algorithm for radiological differential classification (RDC) based on a combination of quantitative and qualitative assessment of lateral spinal radiographs. Radiographs were obtained in a population of 50- to 80-year-old German women (n = 283) and men (n = 297) surveyed in the context of the European Vertebral Osteoporosis Study (EVOS). Morphometric methods (Eastell 3 SD and 4 SD criteria, McCloskey) were validated against RDC and against bone mineral density (BMD) at the femur and the lumbar spine. According to RDC 36 persons (6.2%) had at least one osteoporotic vertebral fracture; among 516 (88.9%) nonosteoporotics 154 had severe spondylosis, 132 had other spinal disease and 219 had normal findings; 14 persons (2.4%) could not be unequivocally classified. The prevalence of morphometrically assessed vertebral deformities ranged from 7.3% to 19.2% in women and from 3.5% to 16.6% in men, depending on the stringency of the morphometric criteria. The agreement between RDC and morphometric methods was poor. In men, 62-86% of cases with vertebral deformities were classified as nonosteoporotic (severe spondylosis or other spinal disease) by RDC, compared with 31-68% in women. Among these, most had wedge deformities of the thoracic spine. On the other hand, up to 80% of osteoporotic vertebral fractures in men and up to 48% in women were missed by morphometry, in particular endplate fractures at the lumbar spine. In the group with osteoporotic vertebral fractures by RDC the proportion of persons with osteoporosis according to the WHO criteria (T-score < -2.5 SD) was 90.0% in women and 86.6% in men

    With improvements in living standards and healthcare, life expectancy has been increasing dramatically in most parts of the world. These situations lead to the increase in the reported cases of geriatrics-related diseases such as hypogonadal osteoporosis with skeletal fracture being the ultimate outcome, which eventually causes significant morbidity and mortality. The deficient gonadal hormones, which are the main cause of hypogonadal osteoporosis, could be substituted with hormone replacement therapy to hinder bone loss. However, the artificial hormonal therapy has been linked to grievous conditions such as breast and prostate cancers. In view of the various adverse effects associated with conventional treatment, many researchers are now focusing on finding alternative remedies from nature. This article explores the possibilities of certain medicinal plants native to Malaysia that possess androgenic and antioxidant properties to potentially be used in the treatment of fracture due to osteoporosis in ageing people.

    This report addresses a new case of a modular femoral neck fracture after total hip arthroplasty. A now seventy-three-year- old overweight female underwent total hip replacement of the right hip because of osteoarthritis in the year 2002. Then, years later, the head and the polyethylene were changed due to wear. In October 2014, the patient was transferred from the trauma department of her hometown to our department after she had slipped and fallen directly on her right hip. The x-rays done at the trauma department have shown no periprosthetic fracture but a fracture of the modular neck. Therefore, the patient was transferred to our department in order to undergo a revision arthroplasty with change of the stem and head after splitting the femur. PMID:26157528

    Using the data of the Baltimore Hip Study 5 (a home-based exercise intervention), this study examined how social support for exercise by experts (SSE-E) affected the self-efficacy, outcome expectations, and exercise behavior among older women following a hip fracture. The total sample included 164 females aged 65 years (M = 81.0; SD = 6.9) who had surgical repair of a non-pathologic hip fracture. Model testing showed a direct relationship between SSE-E and outcome expectations for exercise. There was, however, no direct or indirect relationship between SSE-E and self-efficacy or exercise behavior. The positive effect of SSE-E on the outcome expectations for exercise in older women recovering from a hip fracture provides an opportunity for health care providers in improving physical activity in this population.

    The spiral blade modification of the Dynamic Hip Screw (DHS) was designed for superior biomechanical fixation in the osteoporotic femoral head. Our objective was to compare clinical outcomes and in particular the incidence of loss of fixation. In a series of 197 consecutive patients over the age of 50 years treated with DHS-blades (blades) and 242 patients treated with conventional DHS (screw) for AO/OTA 31.A1 or A2 intertrochanteric fractures were identified from a prospectively compiled database in a level 1 trauma centre. Using propensity score matching, two groups comprising 177 matched patients were compiled and radiological and clinical outcomes compared. In each group there were 66 males and 111 females. Mean age was 83.6 (54 to 100) for the conventional DHS group and 83.8 (52 to 101) for the blade group. Loss of fixation occurred in two blades and 13 DHSs. None of the blades had observable migration while nine DHSs had gross migration within the femoral head before the fracture healed. There were two versus four implant cut-outs respectively and one side plate pull-out in the DHS group. There was no significant difference in mortality and eventual walking ability between the groups. Multiple logistic regression suggested that poor reduction (odds ratio (OR) 11.49, 95% confidence intervals (CI) 1.45 to 90.9, p = 0.021) and fixation by DHS (OR 15.85, 95%CI 2.50 to 100.3, p = 0.003) were independent predictors of loss of fixation. The spiral blade design may decrease the risk of implant migration in the femoral head but does not reduce the incidence of cut-out and reoperation. Reduction of the fracture is of paramount importance since poor reduction was an independent predictor for loss of fixation regardless of the implant being used.

    A significant link between cardiovascular disease and osteoporosis is established in postmenopausal women, but data for men are scarce. We tested the hypothesis that greater severity of abdominal aortic calcification (AAC) was associated with an increased risk of nonspine fracture in 5994 men aged ≥ 65 years. AAC was assessed on 5400 baseline lateral thoracolumbar radiographs using a validated visual semiquantitative score. Total hip bone mineral density (BMD) was measured using dual-energy X-ray absorptiometry. Incident nonspine fractures were centrally adjudicated. After adjustment for age, body mass index (BMI), total hip BMD, fall history, prior fracture, smoking status, comorbidities, race, and clinical center, the risk of nonspine fracture (n=805) was increased among men with higher AAC (hazard ratio [HR] quartile 4 [Q4] [AAC score ≥ 9] versus quartile 1 [Q1] [0-1], 1.36; 96% confidence interval [CI], 1.10-1.68). This association was due to an increased risk of hip fracture (n=178) among men with higher AAC (HR Q4 versus Q1, 2.33; 95% CI, 1.41-3.87). By contrast, the association between AAC and the risk of nonspine, nonhip fracture was weaker and not significant (HR Q4 versus Q1, 1.22; 95% CI, 0.96-1.55). The findings regarding higher AAC and increased risk of fracture were not altered in additional analyses accounting for degree of trauma, estimated glomerular filtration rate, presence of lumbar vertebral fractures (which may bias AAC assessment), preexisting cardiovascular disease, ankle brachial index, or competing risk of death. Thus, in this large cohort of elderly men, greater AAC was independently associated with an increased risk of hip fracture, but not with other nonspine fractures. These findings suggest that AAC assessment may be a useful method for identification of older men at high risk of hip fracture. PMID:23983224

    Hip fracture is a common trauma in older adults with a high incidence of depression, which relates to poorer prognosis including increased risk of infection. Ageing is accompanied by reduced immunity, termed immunesenescence, resulting in increased susceptibility to infection. We examined whether physical trauma (hip fracture) and psychological distress (depressive symptoms) had additive effects upon the aged immune system that might contribute to poor outcomes after injury. Neutrophil function was assessed in 101 hip fracture patients (81 female) 6 weeks and 6 months after injury and 43 healthy age-matched controls (28 female). Thirty eight fracture patients had depressive symptoms at 6 weeks. No difference in neutrophil phagocytosis of Escherichia coli was observed between controls and hip fracture patients, but superoxide production was significantly reduced in hip fracture patients with depressive symptoms compared with patients without symptoms (p = .001) or controls (p = .004) at 6 weeks. Superoxide production improved 6 months following fracture to the level seen in controls. We detected elevated serum cortisol, reduced dehydroepiandrosterone sulphate (DHEAS) and an increased cortisol:DHEAS ratio in fracture patients with depressive symptoms compared with patients without depressive symptoms or controls at 6 weeks and 6 months after injury. Serum IL6, TNFα and IL10 were higher among patients with depressive symptoms at 6 weeks. The cortisol:DHEAS ratio and IL6 levels related to depressive symptom scores but not to neutrophil function. In conclusion, depressive symptoms related to poorer neutrophil function after hip fracture, but this was not driven by changes in stress hormone or cytokine levels. PMID:23876747

    This cross-sectional observational cohort study was designed to simultaneously investigate bone microarchitecture and serum markers of bone metabolism in elderly osteoporotic patients experiencing a trochanteric or femoral neck fracture. Special emphasis was put on renal function, sclerostin and fibroblast growth factor-23 (FGF-23). Eighty-two patients (median age: 84 years; 49 trochanteric fractures) scheduled for emergency surgery due to an osteoporotic fracture participated. Bone specimens for ex vivo microcomputed X-ray tomography were sampled during surgery. Blood samples for laboratory workup were collected before surgery (t0) and 1 day afterward (t1). Fifty-eight patients consented to dual-energy X-ray absorptiometry scanning of the lumbar spine and/or contralateral femoral neck after recovery during the in-patient stay. Samples were grouped according to the site of fracture. Regression coefficients were controlled for age and/or estimated glomerular filtration rate (eGFR), if appropriate. Patients experiencing a femoral neck fracture presented with better preserved renal function (eGFR) and lower C-terminal fragment of fibroblast growth factor-23 (cFGF-23) concentrations compared to those with trochanteric fractures. By contrast, serum sclerostin was similar at both time points and did not differ between groups. Age-adjusted correlation analysis revealed negative associations between eGFR and cFGF-23 determined at t1 (R=-0.34; p<0.05) as well as between eGFR and sclerostin levels at t0 (R=-0.45; p<0.05) in patients with trochanteric and femoral neck fractures, respectively. Our study provides evidence that not only an age-related decline of renal function but also the type of skeletal injury may contribute to the circulating concentrations of cFGF-23. PMID:25439456

    Through retrospective Jeju-cohort study at 2005, we found low rates of detection of osteoporosis (20.1%) and medication for osteoporosis (15.5%) in those who experienced hip fracture. This study was to determine the orthopedic surgeons' awareness could increase the osteoporosis treatment rate after a hip fracture and the patient barriers to osteoporosis management. We prospectively followed 208 patients older than 50 yr who were enrolled for hip fractures during 2007 in Jeju-cohort. Thirty four fractures in men and 174 in women were treated at the eight hospitals. During the study period, orthopedic surgeons who worked at these hospitals attended two education sessions and were provided with posters and brochures. Patients were interviewed 6 months after discharge using an evaluation questionnaire regarding their perceptions of barriers to osteoporosis treatment. The patients were followed for a minimum of one year. Ninety-four patients (45.2%) underwent detection of osteoporosis by dual energy x-ray absorptiometry and 67 (32.2%) were prescribed medication for osteoporosis at the time of discharge. According to the questionnaire, the most common barrier to treatment for osteoporosis after a hip fracture was patients reluctance. The detection and medication rate for osteoporosis after hip fracture increased twofold after orthopedic surgeons had attended the intervention program. Nevertheless, the osteoporosis treatment rate remains inadequate. PMID:22065908

    Background: Osteoporosis is pathophysiologically related to trochanteric fractures, and this condition is more preventable by lifestyle modifications than cervical fractures. We investigated whether older physicians, who are health-conscious people, are at a lower risk of hip fractures because of fewer trochanteric fractures. Methods: Data regarding older (≥65 years) physicians (n = 4303) and matched non-medical persons (control) were retrieved from Taiwan’s National Health Insurance claims. All of the subjects were obtained from NHIRD with index dates from 1 January 2000 to 31 December 2008. Cox proportional hazard and competing risk regression models were established to estimate the hazard ratio (HR) of hip fracture associated with older physicians. Results: The incidence rates of trochanteric fractures were lower in older physicians than in controls (1.73 and 3.07 per 1000 person-years, respectively), whereas the rates of cervical fractures were similar between the two groups (2.45 and 2.12 per 1000 person-years, respectively). Older physicians yielded 46% lower hazard of trochanteric fractures than controls (adjusted HR 0.54, 95% confidence interval 0.37–0.79); by contrast, hazards of cervical fractures were comparable between the two groups. The HRs estimated from the competing risk models remained unchanged. Conclusions: Our findings indicated that health risk awareness may pose a significant preventive effect on trochanteric hip fractures. PMID:25689999

    The aims of this study were to investigate the risk of hip fracture and contributing factors in patients with erectile dysfunction(ED). This population-based study was performed using the Taiwan National Health Insurance Research Database. The analysis included4636 patients aged ≥ 40 years who had been diagnosed with ED (International Classification of Diseases, Ninth Revision, Clinical Modification codes 302.72, 607.84) during 1996–2010. The control group included 18,544 randomly selected age-matched patients without ED (1:4 ratio). The association between ED and hip fracture risk was estimated using a Cox proportional hazard regression model. During the follow-up period, 59 (1.27%) patients in the ED group and 140 (0.75%) patients in the non-ED group developed hip fracture. After adjusting for covariates, the overall incidence of hip fracture was 3.74-times higher in the ED group than in the non-ED group (2.03 vs. 0.50 per 1000 person-years, respectively). The difference in the overall incidence of hip fracture was largest during the 3-year follow-up period (hazard ratio = 7.85; 95% confidence interval = 2.94–20.96; P <0.0001). To the best of our knowledge, this nationwide population-based study is the first to investigate the relationship between ED and subsequent hip fracture in an Asian population. The results showed that ED patients had a higher risk of developing hip fracture. Patients with ED, particularly those aged 40–59 years, should undergo bone mineral density examinations as early as possible and should take measures to reduce the risk of falls. PMID:27078254

    Objectives To characterize outcomes of patients experiencing a fall and subsequent hip fracture while in a nursing home (NH) receiving skilled nursing facility (SNF) services. Design Observational study. Participants Short-stay fee-for-service Medicare beneficiaries who experienced their first hip fracture during a SNF stay. Measurements Outcomes measured in the 90 days after the hip fracture hospitalization included community discharge (with a stay in the community < 30 days), successful community discharge (in the community ≥30 days), death, and institutionalization. Results Between 1999 and 2007, 27,305 hip fractures occurred among short-stay nursing home patients receiving SNF care. After surgical repair of the hip fracture, 83.9% of these patients were discharged from the hospital back to a SNF, with most (99%) returning to the facility where the hip fracture occurred. In the first 90 days after hospitalization, 24.1% of patients died, 7.3% were discharged to the community but remained less than 30 days, 14.0% achieved successful community discharge, and 54.6% were still in a health care institution with almost 46.4% having transitioned to long-term care. Conclusion SNF care aims to maximize the short-stay patient’s independence and facilitate a safe community transition. However, experiencing a fall and hip fracture during the SNF stay was a sentinel event that limited the achievement of this goal. There is an urgent need to ensure the integration of fall prevention into the patient’s plan of care. Further, falls among SNF patients may serve as indicator of quality, which consumers and payers can use to make informed healthcare decisions. PMID:25944177

    We explored the role of transient receptor potential vanilloid 4 (TRPV4) in murine bone metabolism and association of TRPV4 gene variants with fractures in humans. Urinary and histomorphometrical analyses demonstrated reduced osteoclast activity and numbers in male Trpv4(-/-) mice, which was confirmed in bone marrow-derived osteoclast cultures. Osteoblasts and bone formation as shown by serum procollagen type 1 amino-terminal propeptide and histomorphometry, including osteoid surface, osteoblast and osteocyte numbers were not affected in vivo. Nevertheless, osteoblast differentiation was enhanced in Trpv4(-/-) bone marrow cultures. Cortical and trabecular bone mass was 20% increased in male Trpv4(-/-) mice, compared to sex-matched wild type (Trpv4(+/+)) mice. However, at the same time intracortical porosity was increased and bone matrix mineralization was reduced. Together, these lead to a maximum load, stiffness and work to failure of the femoral bone, which were not different compared to Trpv4(+/+) mice, while the bone material was less resistant to stress and less elastic. The differential impacts on these determinants of bone strength were likely responsible for the lack of any changes in whole bone strength in the Trpv4(-/-) mice. None of these skeletal parameters were affected in female Trpv4(-/-) mice. The T-allele of rs1861809 SNP in the TRPV4 locus was associated with a 30% increased risk (95% CI: 1.1-1.6; p=0.013) for non-vertebral fracture risk in men, but not in women, in the Rotterdam Study. Meta-analyses with the population-based LASA study confirmed the association with non-vertebral fractures in men. This was lost when the non-population-based studies Mr. OS and UFO were included. In conclusion, TRPV4 is a male-specific regulator of bone metabolism, a determinant of bone strength, and a potential risk predictor for fractures through regulation of bone matrix mineralization and intra-cortical porosity. This identifies TRPV4 as a unique sexually

    Minimizing post-fracture bone loss is an important aspect of recovery from hip fracture, and determination of factors that affect bone mineral density (BMD) response to treatment after hip fracture may assist in the development of targeted therapeutic interventions. A post hoc analysis of the HORIZON Recurrent Fracture Trial was done to determine the effect of zoledronic acid (ZOL) on total hip (TH) and femoral neck (FN) BMD in subgroups with low-trauma hip fracture. A total of 2127 patients were randomized (1:1) to yearly infusions of ZOL 5 mg (n = 1065) or placebo (n = 1062) within 90 days of operation for low-trauma hip fracture. The 1486 patients with a baseline and at least one post-baseline BMD assessment at TH or FN (ZOL = 745, placebo = 741) were included in the analyses. Percentage change from baseline in TH and FN BMD was assessed at months 12 and 24 and compared across subgroups of hip fracture patients. Percentage change from baseline in TH and FN BMD at months 12 and 24 was greater (p < 0.05) in ZOL-treated patients compared with placebo in most subgroups. Treatment-by-subgroup interactions (p < 0.05) indicated that a greater effect on BMD was observed for TH BMD at month 12 in females, in patients in the lower tertile body mass index at baseline (≤22.6 kg/m2), and in patients with baseline FN BMD T-score of ≤ –2.5; for FN BMD in patients who received ZOL for >6 weeks post-surgery; and for TH and FN BMD in patients with a history of one or more prior fractures. All interactions were limited to the first 12 months after treatment with none observed for the 24-month comparisons. (Clinical trial registration number NCT00046254.) PMID:24839241

    Background The standard care in patients with a painful osteoporotic vertebral compression fracture (VCF) is conservative therapy. Percutaneous vertebroplasty (PV), a minimally invasive technique, is gaining popularity as a new treatment option. Many prospective and retrospective studies have reported on the effectiveness and safety of PV, but no large randomized controlled trial (RCT) has been published. Objective To estimate cost-effectiveness of PV compared to conservative therapy in terms of: pain reduction, quality of life, complications, secondary fractures and mortality. Materials and methods The VERTOS II study is designed as a prospective, multicenter RCT. Patients with a painful VCF with bone edema on MR imaging, local back pain for 6 weeks or less, osteopenia and aged 50 years or older, after obtaining informed consent are included and randomized for PV or conservative therapy. In total 200 patients will be enrolled. Follow-up is at regular intervals during a 1-year period with standard questionnaires, addressing: clinical symptoms, pain medication, Visual Analogue Scale (VAS) score, quality of life and cost-effectiveness. Secondary fractures, necessary additional therapies and complications are recorded. Conclusion The VERTOS II study is the first methodologically sound RCT designed to assess the cost-effectiveness of PV compared to conservative therapy in patients with an acute osteoporotic VCF.

    This study was performed to determine whether patients who sustain an intertrochanteric fracture have better outcomes when stabilized using a sliding hip screw or an intramedullary nail. A 20% sample of Part A and B entitled Medicare beneficiaries 65 years or older was used to generate a cohort of patients who sustained intertrochanteric femur fractures between 1999 and 2001. Two fracture implant groups, intramedullary nail and sliding hip screw, were identified using Current Procedural Terminology and International Classification of Diseases, 9th Revision codes. The cohort consisted of 43,659 patients. Patients treated with an intramedullary nail had higher rates of revision surgery during the first year than those treated with a sliding hip screw (7.2% intramedullary nail versus 5.5% sliding hip screw). Mortality rates at 30 days (14.2% intramedullary nail versus 15.8% sliding hip screw) and 1 year (30.7% intramedullary nail versus 32.5% sliding hip screw) were similar. Adjusted secondary outcome measures showed significant increases in the intramedullary nail group relative to the sliding hip screw group for index hospital length of stay, days of rehabilitation services in the first 6 months after discharge, and total expenditures for doctor and hospital services. Level of Evidence: Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence. PMID:18465180

    We retrospectively reviewed 2989 consecutive patients with a mean age of 81 (21 to 105) and a female to male ratio of 5:2 who were admitted to our hip fracture unit between July 2009 and February 2013. We compared weekday and weekend admission and weekday and weekend surgery 30-day mortality rates for hip fractures treated both surgically and conservatively. After adjusting for confounders, weekend admission was independently and significantly associated with a rise in 30-day mortality (odds ratio (OR) 1.4, 95% confidence interval (CI) 1.02 to 1.9; p = 0.039) for patients undergoing hip fracture surgery. There was no increase in mortality associated with weekend surgery (OR 1.2, 95% CI 0.8 to 1.7; p = 0.39). All hip fracture patients, whether managed surgically or conservatively, were more likely to die as an inpatient when admitted at the weekend (OR 1.4, 95% CI 1.02 to 1.80; p = 0.032), despite our unit having a comparatively low overall inpatient mortality (8.7%). Hip fracture patients admitted over the weekend appear to have a greater risk of death despite having a consultant-led service. PMID:24589794

    Abstract To determine the association between frontal lobe function and risk of hip fracture in patients with Alzheimer disease (AD). Retrospective cohort study using multicenter hospital-based dementia registry and national health insurance claim data was done. Participants who had available data of neuropsychological test, national health insurance claim, and other covariates were included. A total of 1660 patients with AD were included based on Stroop Test results. A total of 1563 patients with AD were included based on the Controlled Oral Word Association Test (COWAT) results. Hip fracture was measured by validated identification criteria using national health insurance claim data. Frontal lobe function was measured by Stroop Test and COWAT at baseline. After adjusting for potential covariates, including cognitive function in other domains (language, verbal and nonverbal memory, and attention), the Cox proportional hazard regression analysis revealed that risk of a hip fracture was decreased with a hazard ratio (HR) of 0.98 per one point of increase in the Stroop Test (adjusted HR = 0.98, 95% confidence interval [CI]: 0.97–1.00) and 0.93 per one point increase in COWAT (adjusted HR = 0.93, 95% CI: 0.88–0.99). The risk of hip fracture in AD patients was associated with baseline frontal lobe function. The result of this research presents evidence of association between frontal lobe function and risk of hip fracture in patients with AD. PMID:26559259

    Purpose We examined the association between predominant dietary patterns and risk of hip fractures in postmenopausal women and men over 50 years. Methods We used data from 74,540 women in the Nurses’ Health Study followed between 1980 and 2010, and 35,451 men from the Health Professionals Follow-up Study followed between 1986 and 2012 for this analysis. Health and lifestyle information was assessed every two years. Diet was assessed approximately every four years with a food frequency questionnaire. Two major dietary patterns were previously derived using principal component analysis. The Prudent pattern is characterized by higher intakes of fruits, vegetables, whole grains, and poultry, and the Western pattern is characterized by higher intakes of red and processed meats, sweets, and refined grains. We computed relative risks (RR) for hip fracture by dietary pattern scores using Cox proportional hazards models, adjusting for potential confounders. Results During follow-up, there were 1891 hip fractures in women and 596 in men. No association was observed between the Prudent or Western pattern and risk of hip fractures in either men or women. We also did not find an association among lean (BMI<25) or overweight (BMI >=25) individuals or among those with higher or lower levels of physical activity. Conclusion Neither the Prudent nor the Western dietary pattern was associated with risk of hip fractures in postmenopausal women or men over 50 years of age. PMID:25731807

    Hip fracture patients represent a large part of the elderly surgical population and face severe postoperative morbidity and excessive mortality compared to adult surgical hip fracture patients. Low antioxidant status and taurine deficiency is common in the elderly, and may negatively affect postoperative outcome. We hypothesized that taurine, an antioxidant, could improve clinical outcome in the elderly hip fracture patient. A double blind randomized, placebo controlled, clinical trial was conducted on elderly hip fracture patients. Supplementation started after admission and before surgery up to the sixth postoperative day. Markers of oxidative status were measured during hospitalization, and postoperative outcome was monitored for one year after surgery. Taurine supplementation did not improve in-hospital morbidity, medical comorbidities during the first year, or mortality during the first year. Taurine supplementation lowered postoperative oxidative stress, as shown by lower urinary 8-hydroxy-2-deoxyguanosine levels (Generalized estimating equations (GEE) analysis average difference over time; regression coefficient (Beta): −0.54; 95% CI: −1.08–−0.01; p = 0.04), blunted plasma malondialdehyde response (Beta: 1.58; 95% CI: 0.00–3.15; p = 0.05) and a trend towards lower lactate to pyruvate ratio (Beta: −1.10; 95% CI: −2.33–0.12; p = 0.08). We concluded that peri-operative taurine supplementation attenuated postoperative oxidative stress in elderly hip fracture patients, but did not improve postoperative morbidity and mortality.

    Biomechanical stereology is proposed as a two-dimensional (2D) finite element (FE) method to estimate the ability of bone tissue to sustain damage and to separate patients with osteoporotic fracture from normal controls. Briefly, 2D nonlinear compact tension FE models were created from quantitative back scattered electron images taken of iliac crest bone specimens collected from the individuals with or without osteoporotic fracture history. The effects of bone mineral microstructure on predicted bone fracture toughness and microcrack propagation were examined. The 2D FE models were used as surrogates for the real bone tissues. The calculated microcrack propagation results and bone mechanical properties were examined as surrogates for measurements from mechanical testing of actual specimens. The results for the 2D FE simulation separated patients with osteoporotic fracture from normal controls even though only the variability in tissue mineral microstructure was used to build the models. The models were deliberately created to ignore all differences in mean mineralization. Hence, the current results support the following hypotheses: (1) that material heterogeneity is important to the separation of patients with osteoporotic fracture from normal controls and; and (2) that 2D nonlinear finite element modeling can produce surrogate mechanical parameters that separate patients with fracture from normal controls.

    Purpose The few studies to date that have examined the relationship between hemoglobin and fracture risk have focused on low hemoglobin values. The present study examined hip fracture risk across the hemoglobin distribution in older non-Hispanic white adults from the third National Health and Nutrition Examination Survey (NHANES III, 1988–1994). Methods Hemoglobin was measured using a Coulter S-plus Jr.® (Coulter Electronics, Hialeah, FL) in 2122 non-Hispanic whites age 65 years and older. Hip fracture cases were identified using linked Medicare and mortality records obtained through 2007. Cox proportional hazards models were used to assess the best-fitting model and to estimate the hazards ratio (HR) for hip fracture by hemoglobin decile before and after adjusting for selected confounders. Results There were 239 hip fracture cases in the analytic sample. The best fitting model was quadratic. When compared to values in the middle of the distribution, those with hemoglobin in the lowest and highest deciles had increased hip fracture risk (HRlowest decile =2.96, 95% CI 1.44–6.08; HRhighest decile = 2.06, 95% CI 1.09–3.92) after adjusting for age and sex. Both HRs remained significant after adjusting for additional confounders (HRlowest decile =2.24, 95% CI 1.09–3.92; HRhighest decile = 2.37, 95% CI 1.35–4.16). Conclusions Both low and high hemoglobin values were associated with increased hip fracture risk. The mechanism underlying the relationship is not clear, but there was some suggestion that it may differ for low versus high hemoglobin. PMID:24938506

    Accurate assessment of hip fracture risk is very important to prevent hip fracture and to monitor the effect of a treatment. A subject-specific QCT-based finite element model was constructed to assess hip fracture risk at the critical locations of femur during the single-leg stance and the sideways fall. The aim of this study was to improve the prediction of hip fracture risk by introducing a novel failure criterion to more accurately describe bone failure mechanism. Hip fracture risk index was defined using cross-section strain energy, which is able to integrate information of stresses, strains, and material properties affecting bone failure. It was found that the femoral neck and the intertrochanteric region have higher fracture risk than other parts of the femur, probably owing to the larger content of cancellous bone in these regions. The study results also suggested that women are more prone to hip fracture than men. The findings in this study have a good agreement with those clinical observations reported in the literature. The proposed hip fracture risk index based on strain energy has the potential of more accurate assessment of hip fracture risk. However, experimental validation should be conducted before its clinical applications. PMID:26601105

    Introduction Hip fractures are a leading cause of mortality and disability worldwide, and the number of hip fractures is expected to rise to over 6 million per year by 2050. The optimal approach for the surgical management of displaced femoral neck fractures remains unknown. Current evidence suggests the use of arthroplasty; however, there is lack of evidence regarding whether patients with displaced femoral neck fractures experience better outcomes with total hip arthroplasty (THA) or hemiarthroplasty (HA). The HEALTH trial compares outcomes following THA versus HA in patients 50 years of age or older with displaced femoral neck fractures. Methods and analysis HEALTH is a multicentre, randomised controlled trial where 1434 patients, 50 years of age or older, with displaced femoral neck fractures from international sites are randomised to receive either THA or HA. Exclusion criteria include associated major injuries of the lower extremity, hip infection(s) and a history of frank dementia. The primary outcome is unplanned secondary procedures and the secondary outcomes include functional outcomes, patient quality of life, mortality and hip-related complications—both within 2 years of the initial surgery. We are using minimisation to ensure balance between intervention groups for the following factors: age, prefracture living, prefracture functional status, American Society for Anesthesiologists (ASA) Class and centre number. Data analysts and the HEALTH Steering Committee are blinded to the surgical allocation throughout the trial. Outcome analysis will be performed using a χ2 test (or Fisher's exact test) and Cox proportional hazards modelling estimate. All results will be presented with 95% CIs. Ethics and dissemination The HEALTH trial has received local and McMaster University Research Ethics Board (REB) approval (REB#: 06-151). Results Outcomes from the primary manuscript will be disseminated through publications in academic journals and presentations

    A 61-year-old man who had undergone revision total hip arthroplasty in 2000 was evaluated at our clinic in 2008, 1 day after feeling an abnormal clicking sensation in his left hip. Radiographs showed a fracture of the alumina ceramic liner of his acetabular component. A second revision total hip arthroplasty was performed with a 28-mm highly crosslinked polyethylene acetabular liner and an alumina femoral head. Sixteen months after the second revision, the patient experience sudden-onset hip pain. Radiographs revealed a fatigue fracture of the neck of a displaced stem. Analysis by scanning electron microscopy of the surface of the retrieved alumina ceramic femoral head revealed no scratches or wear, but analysis of the highly crosslinked polyethylene socket revealed third-body wear, scratches, irregularly shaped dips, and white ceramic particles. Elemental analysis of the white particles by an x-ray microanalyzer revealed the presence of aluminum and oxygen. PMID:21958938

    Background and purpose — Intraoperative periprosthetic femoral fracture is a known complication of cementless total hip arthroplasty (THA). We determined the incidence of—and risk factors for—intraoperative calcar fracture, and assessed its influence on the risk of revision. Patients and methods — This retrospective analysis included 3,207 cementless THAs (in 2,913 patients). 118 intraoperative calcar fractures were observed in these hips (3.7%). A control group of 118 patients/hips without calcar fractures was randomly selected. The mean follow-up was 4.2 (1.8–8.0) years. Demographic data, surgical data, type of implant, and proximal femur morphology were evaluated to determine risk factors for intraoperative calcar fracture. Results — The revision rates in the calcar fracture group and the control group were 10% (95% CI: 5.9–17) and 3.4% (CI: 1.3–8.4), respectively. The revision rate directly related to intraoperative calcar fracture was 7.6%. The Hardinge approach and lower age were risk factors for calcar fracture. In the fracture group, 55 of 118 patients (47%) had at least one risk factor, while only 23 of118 patients in the control group (20%) had a risk factor (p = 0.001). Radiological analysis showed that in the calcar fracture group, there were more deviated femoral anatomies and proximal femur bone cortices were thinner. Interpretation — Intraoperative calcar fracture increased the risk of revision. The Hardinge approach and lower age were risk factors for intraoperative calcar fracture. To avoid intraoperative fractures, special attention should be paid when cementless stems are used with deviant-shaped proximal femurs and with thin cortices. PMID:26541230

    A recognized issue related to metal-on-metal hip resurfacings is early fracture of the femur. Most theories regarding the cause of fracture relate to clinical factors but an engineering analysis of failed hip resurfacings has not previously been reported. The objective of this work was to determine the wear volumes and surface roughness values of a cohort of retrieved hip resurfacings which were removed due to early femoral fracture, infection and avascular necrosis (AVN). Nine resurfacing femoral heads were obtained following early fracture of the femur, a further five were retrieved due to infection and AVN. All fourteen were measured for volumetric wear using a co-ordinate measuring machine. Wear rates were then calculated and regions of the articulating surface were divided into “worn” and “unworn”. Roughness values in these regions were measured using a non-contacting profilometer. The mean time to fracture was 3.7 months compared with 44.4 months for retrieval due to infection and AVN. Average wear rates in the early fracture heads were 64 times greater than those in the infection and AVN retrievals. Given the high wear rates of the early fracture components, such wear may be linked to an increased risk of femoral neck fracture. PMID:26501331

    Fracture of the femoral head and the acetabulum with traumatic dislocation of the hip is a severe injury representing various types and unfavorable outcome. We showed a 45-year-old man with Pipkin type-IV fracture and coxa valga. An immediate closed reduction was achieved followed by open reduction and internal fixation via a posterior approach 6 days later. However, dislocation occurred three times without traumatic events after three weeks. CT demonstrated no displacement of posterior fragments or implant failure. Femoral intertrochanteric varus osteotomy was performed to gain concentric stability and successfully resolved recurrent dislocation. Another 45-year-old woman with Pipkin type-IV fracture and coxa valga also underwent closed reduction initially and then continued conservative treatment. After eight weeks, when she started gait training, progressive pain became symptomatic. Persistent hip pain at weight bearing was not improved in spite of arthroscopic synovectomy and osteochondroplasty. Two years after injury, femoral intertrochanteric varus osteotomy was indicated and her refractory pain was resolved gradually. We suggest that femoral varus osteotomy should be considered for superolateral subluxation associated fracture dislocation of the hip in Pipkin type-IV and coxa valga. PMID:27293934

    Introduction: Hip fracture is associated with substantial morbidity and mortality. A large integrated health care system developed a registry to characterize its current patient population with hip fractures. This report describes the population, methods used, and outcomes of patients registered during the initial three years (2009–2011). Methods: Cases of hip fracture recorded from January 2009 through December 2011 were ascertained using the Kaiser Permanente Hip Fracture Registry. The registry collects information on patient, procedure, surgeon, facility, and surgical outcomes. Outcomes monitored included length of stay, readmissions, mortality, revisions, surgical site infections, deep vein thrombosis, pulmonary embolism, pneumonia, pressure ulcers, dislocations, and myocardial infarction. Results: The population (N = 12,562) was predominantly white (77.8%), women (68.6%), and older (71.6% aged ≥ 75 years), and 32% had at least 5 comorbidities. The average length of follow-up was 1.1 years (standard deviation = 0.9). The most prevalent comorbidities were hypertension (70.8%) and anemia (29.4%). Femoral neck fractures (54.6%) were the most common fracture type. Hemiarthroplasty was the most common procedure (33.1%). Most fractures were treated by medium-volume (10 to 29 cases per year) surgeons (68.4%) at high-volume (≥ 130 cases per year) facilities (63.0%). The 90-day readmission rate was 22.1%, and the mortality rate was 12.3%. The most common postoperative complications were pneumonia (11.4%) and pressure ulcers (2.9%). There were 2.2 revisions per 100 observation years. Conclusion: A hip fracture registry provides important information regarding patient characteristics, intraoperative practices, and postoperative outcomes, which can be analyzed, interpreted, and used to reduce morbidity and mortality.

    The purpose of this prospective study was to monitor the bone mineral density (BMD) of the lumbar spine and contralateral femoral neck in the first year following an osteoporosis-related fracture of the hip. Eighty-three elderly patients (mean age 77 years) who had sustained a hip fracture had determinations of BMD made at the time of fracture; 49 of these patients were available for reassessment of BMD 1 year later. The change in BMD was correlated with pre- and postinjury variables, such as ambulatory ability, dietary intake of calcium, serum vitamin D levels, mental status, and routine serologies. The mean decrease in BMD in the year following fracture was 5.4% from the contralateral femoral neck and 2.4% from the lumbar spine. Calcium intake correlated with the loss of BMD from the femoral neck (p = 0.015), but not the lumbar spine. Patients with daily calcium intakes of less than 500 mg/day had a more than 10% decrease in femoral neck BMD in the year following their hip fracture. Serum 1,25-dihydroxy vitamin D level correlated with loss of MBD from the lumbar spine (p = 0.001), but not from the femoral neck. There was no correlation between the loss of bone mineral from either measurement site and age, sex, level of ambulation, or mental status. The loss of BMD from the femoral neck in the year following a hip fracture is more than five times that reported in the nonfractured population. This accelerated rate of loss can have drastic consequences in an elderly population already exhibiting osteopenia and propensity to fall. Investigation of pharmacologic or other interventions in the first critical year following a hip fracture may potentially blunt this accelerated rate of bone loss and lessen the risk of subsequent fractures.

    The purpose of this study was to evaluate adherence to home-based exercise interventions among older women post hip fracture that were randomized to one of three exercise intervention groups or a routine care group. A total of 157 female hip fracture patients provided data for the intervention analysis. Factors evaluated baseline, 2, 6, and 12 months post hip fracture included demographic variables, adherence to treatment visits, self-efficacy, outcome expectations, stage of change for exercise, social support for exercise, mood, health status, pain, and fear of falling. The hypothesized model tested the direct and indirect impact of all study variables on adherence to exercise intervention sessions. Different factors appeared to influence adherence to visits across the recovery trajectory. PMID:20428489

    Background Vertebral compression fractures (VCFs) can cause significant pain and functional impairment, and their cumulative effect can lead to progressive morbidity. This single-arm, prospective feasibility trial, conducted at 4 clinical sites, was undertaken to evaluate the clinical outcomes associated with the use of an innovative vertebral augmentation device, the Kiva VCF Treatment System (Benvenue Medical, Santa Clara, California), in the management of symptomatic VCFs associated with osteoporosis. Methods Vertebral augmentation treatment was performed for persistent back pain symptoms in 57 patients (mean age, 71.9 ± 10.4 years), including 46 women, with radiologically confirmed VCFs; 36 of these patients (63%) had reached 12 months of follow-up at this data analysis. There were 51 one-level cases, 5 two-level cases, and 1 three-level case, representing 64 treated levels. Back pain severity and condition-specific functional impairment were evaluated with a standard 100-mm visual analog scale and the Oswestry Disability Index (ODI), respectively, before device implantation as well as at 6 weeks, 3 months, and 12 months. Results Marked clinical improvements were realized in back pain severity and functional impairment through 12 months of follow-up. The mean back pain score on the visual analog scale improved from 79.3 ± 17.2 before treatment to 21.9 ± 21.3, 21.9 ± 24.6, and 23.2 ± 23.3 at 6 weeks, 3 months, and 12 months, respectively. The mean decrease at 12 months was 49.9 ± 30.3 mm, or approximately 66% (P < .0001). Similarly, the mean ODI score improved from 68.1% ± 16.9% before treatment to 27.4% ± 17.2%, 23.8% ± 18.7%, and 23.3% ± 15.5% at 6 weeks, 3 months, and 12 months, respectively, representing a mean change of 39.2 ± 19.6 percentage points, or approximately 63%, at 12 months. Overall clinical success rates based on a 30% improvement in pain severity or greater and maintenance or improvement in the ODI were 91%, 88%, and 89% at 6 weeks

    Objectives: Objective and clinical results of microfracture for treatment of chondral defects of the knee is well documented, yet outcomes for microfracture of the hip have not been extensively studied. Recently, several studies demonstrated clinical improvements in patients treated with microfracture of the hip. The purpose of this study is to examine clinical outcomes and survivorship in patients who underwent microfracture during arthroscopic hip surgery. Methods: A retrospective analysis of a prospectively collected database was performed. Thirty-eight patients with a mean age of 41 (range, 17-64) who underwent microfracture during arthroscopic hip surgery by a single surgeon (senior author) were identified. Demographic data, diagnosis, and details regarding operative procedures were collected. All patients were indicated for hip arthroscopy based on standard pre-operative examination as well as routine and advanced imaging. Baseline pre-operative modified Harris Hip Scores (mHHS) and Non-Arthritic Hip Scores (NAHS) were compared to mHHS and NAHS at two-year follow-up. Additionally, survivorship data was assessed to determine failure, defined as any subsequent revision arthroscopic surgery and/or hip arthroplasty of the same hip. Results: Thirty-four of the 38 (89.5%) patients were available for two-year clinical follow-up. Baseline mean mHHHS and NAHS for all patients improved from 50.6 (+/- 12.7) and 46.9 (+/-12.8) to 84.7 (+/- 12.5) and 85.6 (+/- 11.2) respectively. Both improvements were statistically significant (p < 0.05). Eight patients (23.5%) met failure criteria and underwent additional surgery at an average of 23.9 months. Two patients (5.8%) underwent revision arthroscopic surgery, and six patients (17.7%) underwent hip arthroplasty. Conclusion: Significant improvements in clinical outcomes are seen at two-year follow-up after microfracture treatment of chondral lesions of the hip. Despite overall success, failure rates are relatively high. As with

    Background and purpose - Hip fracture patients usually have low body mass index (BMI), and suffer further postoperative catabolism. How BMI relates to outcome in relatively healthy hip fracture patients is not well investigated. We investigated the association between BMI, survival, and independent living 1 year postoperatively. Patients and methods - This prospective multicenter study involved 843 patients with a hip fracture (mean age 82 (SD 7) years, 73% women), without severe cognitive impairment and living independently before admission. We investigated the relationship between BMI and both 1-year mortality and ability to return to independent living. Results - Patients with BMI > 26 had a lower mortality rate than those with BMI < 22 and those with BMI 22-26 (6%, 16%, and 18% respectively; p = 0.006). The odds ratio (OR) for 1-year survival in the group with BMI > 26 was 2.6 (95% CI: 1.2-5.5) after adjustment for age, sex, and physical status. Patients with BMI > 26 were also more likely to return to independent living after the hip fracture (OR = 2.6, 95% CI: 1.4-5.0). Patients with BMI < 22 had similar mortality and a similar likelihood of independent living to those with BMI 22-26. Interpretation - In this selected group of patients with hip fracture, the overweight and obese patients (BMI > 26) had a higher survival rate at 1 year, and returned to independent living to a higher degree than those of normal (healthy) weight. The obesity paradox and the recommendations for optimal BMI need further consideration in patients with hip fracture. PMID:26986549

    Objective To determine the association between thyroid hormone levels and sleep quality in community-dwelling men. Methods Among 5,994 men aged ≥65 years in the Osteoporotic Fractures in Men (MrOS) study, 682 had baseline thyroid function data, normal free thyroxine (FT4) (0.70 ≤ FT4 ≤ 1.85 ng/dL), actigraphy measurements, and were not using thyroid-related medications. Three categories of thyroid function were defined: subclinical hyperthyroid, thyroid-stimulating hormone (TSH) <0.55 mIU/L; euthyroid (TSH, 0.55 to 4.78 mIU/L); and subclinical hypothyroid (TSH >4.78 mIU/L). Objective (total hours of nighttime sleep [TST], sleep efficiency [SE], wake after sleep onset [WASO], sleep latency [SL], number of long wake episodes [LWEP]) and subjective (TST, Pittsburgh Sleep Quality Index score, Epworth Sleepiness Scale score) sleep quality were measured. The association between TSH and sleep quality was examined using linear regression (continuous sleep outcomes) and log-binomial regression (categorical sleep outcomes). Results Among the 682 men examined, 15 had subclinical hyperthyroidism and 38 had subclinical hypothyroidism. There was no difference in sleep quality between subclinical hypothyroid and euthyroid men. Compared to euthyroid men, subclinical hyperthyroid men had lower mean actigraphy TST (adjusted mean difference [95% confidence interval (CI)], −27.4 [−63.7 to 8.9] minutes) and lower mean SE (−4.5% [−10.3% to 1.3%]), higher mean WASO (13.5 [−8.0 to 35.0] minutes]), whereas 41% had increased risk of actigraphy-measured TST <6 hours (relative risk [RR], 1.41; 95% CI, 0.83 to 2.39), and 83% had increased risk of SL ≥60 minutes (RR, 1.83; 95% CI, 0.65 to 5.14) (all P>0.05). Conclusion Neither subclinical hypothyroidism nor hyperthyroidism is significantly associated with decreased sleep quality. PMID:24449663

    Fracture prediction models help identify individuals at high risk who may benefit from treatment. Area Under the Curve (AUC) is used to compare prediction models. However, the AUC has limitations and may miss important differences between models. Novel reclassification methods quantify how accurately models classify patients who benefit from treatment and the proportion of patients above/below treatment thresholds. We applied two reclassification methods, using the NOF treatment thresholds, to compare two risk models: femoral neck BMD and age (“simple model”) and FRAX (”FRAX model”). The Pepe method classifies based on case/non-case status and examines the proportion of each above and below thresholds. The Cook method examines fracture rates above and below thresholds. We applied these to the Study of Osteoporotic Fractures. There were 6036 (1037 fractures) and 6232 (389 fractures) participants with complete data for major osteoporotic and hip fracture respectively. Both models for major osteoporotic fracture (0.68 vs. 0.69) and hip fracture (0.75 vs. 0.76) had similar AUCs. In contrast, using reclassification methods, each model classified a substantial number of women differently. Using the Pepe method, the FRAX model (vs. simple model), missed treating 70 (7%) cases of major osteoporotic fracture but avoided treating 285 (6%) non-cases. For hip fracture, the FRAX model missed treating 31 (8%) cases but avoided treating 1026 (18%) non-cases. The Cook method (both models, both fracture outcomes) had similar fracture rates above/below the treatment thresholds. Compared with the AUC, new methods provide more detailed information about how models classify patients. PMID:21351143

    There is controversy about whether or not body parameters affect hip fracture in men and women in the same way. In addition, although bone mineral density (BMD) is currently the most important single discriminator of hip fracture, it is unclear if BMD alone is equally effective for men and women. The objective of this study was to quantify and compare the associations of hip fracture risk with BMD and body parameters in men and women using our recently developed two-level biomechanical model that combines a whole-body dynamics model with a proximal-femur finite element model. Sideways fall induced impact force of 130 Chinese clinical cases, including 50 males and 80 females, were determined by subject-specific dynamics modeling. Then, a DXA-based finite element model was used to simulate the femur bone under the fall-induced loading conditions and calculate the hip fracture risk. Body weight, body height, body mass index, trochanteric soft tissue thickness, and hip bone mineral density were determined for each subject and their associations with impact force and hip fracture risk were quantified. Results showed that the association between impact force and hip fracture risk was not strong enough in both men (r=-0.31,p<0.05) and women (r=0.42,p<0.001) to consider the force as a sole indicator of hip fracture risk. The correlation between hip BMD and hip fracture risk in men (r=-0.83,p<0.001) was notably stronger than that in women (r=-0.68,p<0.001). Increased body mass index was not a protective factor against hip fracture in men (r=-0.13,p>0.05), but it can be considered as a protective factor among women (r=-0.28,p<0.05). In contrast to men, trochanteric soft tissue thickness can be considered as a protective factor against hip fracture in women (r=-0.50,p<0.001). This study suggested that the biomechanical risk/protective factors for hip fracture are sex-specific. Therefore, the effect of body parameters should be considered differently for men and women in hip

    The current Medicare reimbursement for hip fractures lacks accountability and promotes cost cutting. A bundled payment system-analogous to the Medicare Acute Care Episodes Demonstration for Orthopedic and Cardiovascular Surgery-may help curtail costs, foster communication among health care providers, and improve their accountability for patient outcomes. In hip fracture care, bundled payment may spur development of multidisciplinary best practice guidelines, quality assessment, and reporting, and result in benchmarking and best practices sharing. However, its implementation may face challenges: the need for quality assessment criteria and risk adjustment methods and possible risks of pushing costs outside of Medicare boundaries.

    This study was conducted to investigate the effects of depression and antidepressant medications on hip fracture. The database of the Taiwan National Health Insurance with medical records of more than 1,000,000 individuals was searched for patients who had hip fracture with or without depression from 1998 to 2009. Patients with the following conditions were excluded: hip fracture due to cancer or traffic accidents, hip fracture that occurred before the diagnosis of depression, and use of antidepressants before the diagnosis of depression. A matched cohort of 139,110 patients was investigated, including 27,822 (17,309 females; 10,513 males) with depression and 111,288 (69,236 females; 42,052 males) without depression (1:4 randomly matched with age, sex, and index date). Among these patients, 232 (158 females and 74 males) had both hip fracture and depression, and 690 (473 females and 217 males) had hip fracture only. The Cox proportional-hazards regression method was used to determine the effect of depression on hip fracture. The hazard ratio (HR) for each clinical parameter was calculated after adjusting for confounders including sex, age, Charlson comorbidity index, urbanization, osteoporosis, and antidepressants. Results showed that patients with major depressive disorder had a 61% higher incidence of hip fracture than those without depression (HR 1.61, 95% confidence interval [CI] 1.19-2.18, P = 0.002). The risk of hip fracture for patients with less severe depressive disorder (dysthymia or depressive disorder, not otherwise specified) was not statistically higher than that of patients with no depression (HR 1.10, 95% CI = 0.91-1.34, P = 0.327). Among the patients with depression, females had a 49% higher incidence for hip fracture than males (HR 1.49, 95% CI 1.30-1.72, P < 0.001). The incidence of hip fracture also increased with age and Charlson comorbidity index scores. Analyses of both all (139,110) patients and only patients (27,822) with depression

    With an annual incidence greater than 65,000 in the United Kingdom, hip fractures are a common but debilitating injury predominantly affecting those over 65. Treatment is based on the anatomical location of the fracture relative to the capsule of the hip joint - fractures occurring within it are treated by arthroplasty, while extracapsular fractures are an indication for fixation. Intertrochanteric fractures are further grouped as stable (AO/OTA 31A1/A2) or unstable (31A3) which in turn governs in the current UK guidelines whether this fixation is achieved with a dynamic hip screw or intramedullary device. Anecdotally, some units are tending towards intramedullary devices for 31A2 fractures as well, a practice which from the evidence does not appear to confer benefit and carries an excess cost. We reviewed our data submitted to the National Hip Fracture Database over the last five years and identified all intertrochanteric fractures, from which cohort we identified all patients with 31A2 fractures by review of radiographs. The cohort comprised 370 patients. We then recorded age, gender, ASA grade, abbreviated mental test score, residence from where admitted, length of stay, destination on discharge and whether any further operations were required. There was no significant difference in the demographics of the groups, year-on-year, except gender mix. There was a significant, twenty-fold rise in the use of intramedullary devices between 2011 and 2015. Length of stay, length of overall episode of care, revision rates, mortality and destination on discharge were unchanged. This use is not supported by NICE guidelines and this study offers no evidence to contradict this position. We advocate all centres examine their practice to avoid a costly intervention without clinical benefit. PMID:27222104

    Indications for and benefits of providing osteoporosis (OP) care for hip fracture patients have become widely understood. The hip fracture patient is frequently over age 80 years, minimally ambulatory, has multiple medical comorbidities, and has cognitive impairment. Patient barriers to initiation of effective OP treatment include: age, dementia, medical comorbidities, polypharmacy, lack of adherence with treatment, alcohol abuse, postoperative delirium, language barriers, inadequate social support, and socioeconomic status. In a large teaching hospital, 244 patients presented with hip fracture over 2 years: 72% were female and 64% were over age 80. Forty percent had been diagnosed with dementia; another 29% had other severe medical comorbidities.Opportunities for OP diagnosis and treatment are numerous. In acute care hospitals, coordinator facilitated programs are effective for identification, education, assessment, referral, and treatment of underlying OP in fracture patients. System modifications may include an automated care path or automatic specialist referral for hip fracture patients. In the rehabilitation hospital, the patients are in a more stable condition, there is a focus on the recent fracture, and there are opportunities to initiate OP treatment and to promote adherence. In long-term care, dietary intake including calcium and vitamin D supplementation and persistence with pharmacotherapy can be monitored. Patient education and referral to the family physician for osteoporosis investigation and treatment have improved patient knowledge and diagnosis, but the reported impact on treatment has been limited.Effective OP care for the vulnerable hip fracture patient should be initiated early but may be complex and require coordination. In addition to calcium and vitamin D supplementation, most patients in this category have an indication for aminobisphosphonate therapy.

    The current bundled payment reimbursement from the Centers for Medicare & Medicaid Services will not cover the additional cost of hospital readmission for the same diagnosis, and patients with hip fractures have one of the highest cost-saving opportunities when compared with other admission reasons. Common reasons for readmission to the hospital after hip fracture include pneumonia, dehydration, and mobility issues. The learning modalities including visual, aural, read/write, and kinesthetic were used to make recommendations on how the education can be incorporated into the instruction of patients with hip fractures and their families. These learning techniques can be used to develop education to decrease possibility of 30-day readmission after hip fracture. Nurses must focus their education to meet the needs of each individual patient, adapting to different types of adult learners to increase the health literacy of patients with hip fractures and their families.

    2016-01-01

    Vertebral compression fractures (VCF's) are the most common form of osteoporotic fractures. Whether symptomatic or asymptomatic, they both represent a high risk for not only vertebral but also nonvertebral fractures in untreated populations. This high risk of future fracture after a VCF is independent of the T-score because bone strength is a combination of bone mineral density and bone quality. VCFs are the single greatest risk for future fractures at all other skeletal sites in untreated populations, including hip fractures. They are often unrecognized despite their exceptionally high prevalence in all genders and most ethnic groups as age increases. This article highlights some of the key messages about VCF's, and how assessment for their presence and then management will reduce the risk of all osteoporotic fractures. PMID:26439186

    Hip fracture is a common physical trauma in older adults that is also associated with a high incidence of new onset depression. The immune system declines with age and is also compromised by physical and psychological stress. This study examined whether hip fracture and depressive symptoms had additive effects upon the aged immune system that might contribute to poor health outcomes after hip fracture. We assessed the frequency of regulatory T cells, Tregs (CD4(+) CD25(+) Foxp3(+)) and IL10 production by CD4 T cells, and the frequency and IL10 production by regulatory B cells, Bregs (CD19(+) CD24(hi) CD38(hi)) in 101 hip fracture patients (81 female) 6 weeks after injury and 43 healthy age-matched controls (28 female). 38 hip fracture patients (37%) developed depressive symptoms. Hip fracture did not have an effect on circulating Tregs frequency but a significant reduction in the frequency of Bregs was observed in patients who developed depression compared with non-depressed patients (p = 0.001) or healthy controls (p < 0.001). Bregs also showed a significant decline in IL10 production in depressed hip fracture patients compared with controls (p = 0.04) and non-depressed patients (p = 0.01). In contrast, there was an increase in IL10 production by CD4 T cells in hip fracture patients with new onset depression compared to hip fracture patients without depression (p = .04) and healthy controls (p = .02). We conclude that the reduced immunity associated with new onset depression post hip fracture could include a contribution by heightened Tregs function. PMID:26112234

    We have reviewed 178 intertrochanteric fractures treated by dynamic hip screw (DHS) fixation between March 1995 and December 1999 and followed for a minimum of 1 year. We used Singh's classification of the trabecular bone structure in the proximal femur as a measure of osteoporosis and also classified the fractures according to three different systems (Boyd-Griffin, Evans, AO). The postoperative radiographs were examined for loss of reduction, i.e. varus angulation >100, perforation of the femoral head, more than 20-mm extrusion of a lag screw or metal failure. We found 49 cases which showed radiographic failures. Two were stable fractures and 47 unstable fractures (Evans' classification). Unstable fractures with osteoporosis had a failure rate of more than 50%. In such cases DHS should not be the first choice for treatment. PMID:11820441

    Sarcopenia-related falls and fractures are increasing worldwide due to the aging population. The purpose of this study was to 1) evaluate anthropometric characteristics related to hip fracture in Korean patients, 2) investigate sarcopenia prevalence in hip fracture (HF) and non-hip fracture (NF) groups, and 3) investigate the correlation between sarcopenia and osteoporosis. This case-control study examined 359 HF and 1,614 NF normal populations using Korea National Health and Nutrition Examination Survey data. We performed whole-body dual energy X-ray absorptiometry to analyze body composition using the skeletal muscle mass index (SMI: lean mass/height²) and bone mineral density (BMD). In the HF group, using the AWGS definition, the prevalence of sarcopenia in women and men was 44.3% and 68.2%, respectively; in the NF group, it was 7.1% and 16.1%, respectively. Lower appendicular SMI (P < 0.001), leg muscle mass (P < 0.001), and higher prevalence of sarcopenia (P < 0.001) were observed in the HF group after adjustment for age and gender. In multivariate analysis, sarcopenia (OR = 6.52; 95% CI = 4.67-9.09), age (OR = 1.15; 95% CI = 1.13-1.17), and osteoporosis (OR = 1.87; 95% CI = 1.35-2.58) were associated with the occurrence of a hip fracture. This study showed a higher prevalence of sarcopenia in patients with hip fractures compared with a normal population, and higher prevalence of sarcopenia in men. PMID:27510394

    Background & Aims Chronic hepatitis B (CHB) infection is associated with reduced bone mineral density, but its association with fractures is unknown. Our objectives were to determine whether untreated or treated CHB-infected persons are at increased risk for hip fracture compared to uninfected persons. Methods We conducted a cohort study among 18,796 untreated CHB-infected, 7,777 treated CHB-infected, and 979,751 randomly sampled uninfected persons within the U.S. Medicaid populations of California, Florida, New York, Ohio, and Pennsylvania (1999 – 2007). CHB infection was defined by two CHB diagnoses recorded >6 months apart and was classified as treated if a diagnosis was recorded and antiviral therapy was dispensed. After propensity score matching of CHB-infected and uninfected persons, Cox regression was used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) of incident hip fracture in: 1) untreated CHB-infected versus uninfected, and 2) treated CHB-infected versus uninfected patients. Results Untreated CHB-infected patients of black race had a higher rate of hip fracture than uninfected black persons (HR, 2.55 [95% CI, 1.42 – 4.58]). Compared to uninfected persons, relative hazards of hip fracture were increased for untreated white (HR, 1.26 [95% CI, 0.98 – 1.62]) and Hispanic (HR, 1.36 [95% CI, 0.77 – 2.40]) CHB-infected patients, and treated black (HR, 3.09 [95% CI, 0.59 – 16.22) and white (HR, 1.90 [95% CI, 0.81 – 4.47]) CHB-infected patients, but these associations were not statistically significant. Conclusions Among U.S. Medicaid enrollees, untreated CHB-infected patients of black race had a higher risk of hip fracture than uninfected black persons. PMID:24713185

    Hip fractures can lead to functional disability and high mortality rates among elderly patients. The aim of this study was to investigate whether chronic obstructive pulmonary disease (COPD) is a risk factor for hip fracture. A retrospective population-based 4-year cohort study was conducted using case-control matched analysis of data from the Taiwan Longitudinal Health Insurance Database 2005 (LHID2005). Patients with a diagnosis of COPD between January 1, 2004 and December 31, 2007 were enrolled. A 2-stage approach and data from the National Health Interview Survey 2005 were applied to adjust for missing confounders in the LHID2005 cohort. Hazard ratios (HRs) and adjusted HRs were estimated hip fracture risk for the COPD. We enrolled 16,239 patients in the COPD cohort and 48,747 (1:3) patients in non-COPD cohort. The hip fracture incidences were 649 per 100,000 person-years in the study cohort and 369 per 100,000 person-years in non-COPD cohort. The hip fracture HR during the follow-up period was 1.78 (P < 0.001) and the adjusted hip fracture HR was 1.57 (P < 0.001) after adjustment for covariates by using the 2-stage approach method. Patients with COPD were at hip fracture risk and fracture-prevention strategies are essential for better quality of care. PMID:26987933

    Objective. To evaluate differences in the short-term relationship between weather conditions and the incidence of hip fracture in people aged 65 and over among two regions of Spain. Methods. Hip fracture incidence was calculated for the years 2000–2008 for residents of Health Area 14 in Valencian Community (Mediterranean climate) and the “Mancha Centro” Health Area in Castilla-La Mancha (inland climate), Spain. The relationship between hip fracture incidence and weather was analyzed with a case-crossover design and explored in subgroups defined by sex, age, and fracture type. Results. In the inland area, a positive and significant tendency for hip fracture incidence was observed (annual increase: 1.5%) whereas in the Mediterranean area a seasonal increase of 9% was noted in autumn and winter with respect to spring. Weather conditions, especially wind, were significantly associated with hip fracture incidence: days with more frequent windy periods and/or a greater wind velocity were associated with an increase in hip fracture incidence of 51% in the Mediterranean area and 44% in the inland area. Conclusions. Hip fracture incidence exhibits seasonal changes that differ between the Mediterranean and inland areas. The short-term relationship with climate, although similar in both areas, may partly explain these seasonal changes. PMID:25759722

    The scaling index method (SIM) is a recently proposed non-linear technique to extract texture measures for the quantitative characterisation of the trabecular bone structure in high resolution magnetic resonance imaging (HR-MRI). The three-dimensional tomographic images are interpreted as a point distribution in a state space where each point (voxel) is defined by its x, y, z coordinates and the grey value. The SIM estimates local scaling properties to describe the nonlinear morphological features in this four-dimensional point distribution. Thus, it can be used for differentiating between cluster-, rod-, sheet-like and unstructured (background) image components, which makes it suitable for quantifying the microstructure of human cancellous bone. The SIM was applied to high resolution magnetic resonance images of the distal radius in patients with and without osteoporotic spine fractures in order to quantify the deterioration of bone structure. Using the receiver operator characteristic (ROC) analysis the diagnostic performance of this texture measure in differentiating patients with and without fractures was compared with bone mineral density (BMD). The SIM demonstrated the best area under the curve (AUC) value for discriminating the two groups. The reliability of our new texture measure and the validity of our results were assessed by applying bootstrapping resampling methods. The results of this study show that trabecular structure measures derived from HR-MRI of the radius in a clinical setting using a recently proposed algorithm based on a local 3D scaling index method can significantly improve the diagnostic performance in differentiating postmenopausal women with and without osteoporotic spine fractures.

    Age-specific hip fracture incidence has been increasing in some parts of the world. The incidence of hip fractures among Japanese on the island of Oahu, Hawaii in 1979-1981 was approximately half that of Caucasians in North America, but similar to the incidence in Japan. We surveyed the incidence on Oahu again in 1991-1995 for all races to compare the incidence among Japanese to the earlier rates, and to other populations, including Caucasians on Oahu. The incidence of hip fracture among Japanese in Hawaii between 1991-1995 had not changed appreciably (compared to 1979-1981), and was similar to that among Caucasians on Oahu. The incidence among Hawaii Japanese and Caucasians was similar to, or lower than Japan overall, and much lower (one-third to one-half) than that reported for Caucasians in North America and Northern Europe, suggesting that the prevalence of certain risk factors may be lower in Hawaii. These findings confirm other studies suggesting that nongenetic factors may be responsible for much of the observed differences in hip fracture incidence between countries, and between races.

    BACKGROUND: Effective analgesia is essential for the postoperative care of orthopedic patients. OBJECTIVES: To evaluate the efficacy of continuous fascia iliaca compartment block (FIB) as postoperative analgesia after hip fracture surgery, and to compare FIB with patient-controlled intravenous analgesia (PCIA) using fentanyl for 48 h postoperatively. METHODS: Patients with hip fractures who were scheduled for open reduction and internal fixation surgery using the antirotation proximal femoral nail technique were randomly assigned to the FIB or PCIA groups. Postoperative pain was assessed using a numeral rating scale at 2 h, 4 h, 6 h, 12 h, 24 h and 48 h after analgesia was started. Delirium, postoperative nausea and vomiting (PONV), and pruritus were also monitored. RESULTS: Patients in the FIB group reported less pain than those in the PCIA group (P=0.039, d=−0.3). The change in pain scores over time was similar between the two groups. There were six patients with PONV and five patients with pruritus in the PCIA group, while no PONV or pruritus was noticed in the FIB group (P=0.013). Ten (19.6%) patients in the FIB group and three (5.7%) patients in the PCIA group developed postoperative delirium (P=0.032, d=0.77). CONCLUSION: Continuous FIB is a safe and effective technique for postoperative analgesia after hip fracture surgery, making it an option for pain management in elderly patients with hip fractures.

    ABSTRACT Purpose: Best rehabilitation practices after hip fracture for people with dementia have not been established. A systematic review was conducted to determine current evidence for rehabilitation in this population, including residents in continuing care. Methods: Standardized review methodology was used to search eight databases for literature on hip-fracture rehabilitation for people with dementia. Eligible studies included participants with dementia who had a hip fracture; performed a rehabilitation intervention; and evaluated one or more of function, ambulation, discharge location, or falls. The Newcastle–Ottawa Scale was used to assess validity. Results: A total of 13 studies were included: five randomized controlled trials (RCTs), seven prospective cohort series, and one retrospective cohort study. Average quality ratings for RCTs and cohort studies were good and fair respectively. Participants with mild to moderate dementia receiving rehabilitation showed similar relative gains in function to those without dementia. Only one study examined the effect of rehabilitation among residents in continuing care. Conclusions: People with mild or moderate dementia may show improved function and ambulation and decreased fall risk after rehabilitation post hip fracture, similar to gains achieved by those without dementia. More research is required to ascertain the effect of rehabilitation in people with moderate to severe dementia, including those residing in continuing-care settings. PMID:23449813

    We conducted a prospective study to evaluate the prevalence of cognitive impairment (CI) in elderly inpatients awaiting surgery for hip fracture, and to compare CI and normal cognition (NC) patients with respect to preoperative pain, fear, and anxiety. The study included patients who were older than 65 years when admitted to a hospital after acute hip fracture. Preoperative assessment involved use of Confusion Assessment Method-Short Form, Montreal Cognitive Assessment (MoCA), visual analog scales for anxiety and fear, and Wong-Baker Faces Pain Scale. Patients with delirium were excluded from the study. Patients with CI and NC, as determined by MoCA score, were compared for each assessment. Of the 65 hip fracture patients enrolled, 62 had evaluable cognitive data. Of these 62 patients, 23 (37.1%) had NC (MoCA score, ≥ 23) and 39 (62.9%) had CI (MoCA score, < 23). Only 5 (7.7%) of the 65 patients had a documented diagnosis of CI or dementia at time of hospitalization. Mean preoperative pain scores were significantly (P < .001) higher for CI patients (5.3) than for NC patients (2.8). Our study results showed that many elderly hip fracture patients had unrecognized CI before surgery, and CI patients had significantly more pain than NC patients did. Appropriate identification of preoperative CI and treatment of pain are crucial in optimizing patient outcomes. PMID:25046191

    Background Hip fracture surgery on elderly patients is associated with a high incidence of morbidity and mortality. The aim of this study is to identify the risk factors related to the postoperative mortality and complications following hip fracture surgery on elderly patients. Methods In this retrospective study, the medical records of elderly patients (aged 65 years or older) who underwent hip fracture surgery from January 2011 to June 2014 were reviewed. A total of 464 patients were involved. Demographic data of the patients, American Society of Anesthesiologists physical status, preoperative comorbidities, type and duration of anesthesia and type of surgery were collected. Factors related to postoperative mortality and complications; as well as to intensive care unit admission were analyzed using logistic regression. Results The incidence of postoperative mortality, cardiovascular complications, respiratory complications and intensive care unit (ICU) admission were 1.7, 4.7, 19.6 and 7.1%, respectively. Postoperative mortality was associated with preoperative respiratory comorbidities, postoperative cardiovascular complications (P < 0.05). Postoperative cardiovascular complications were related to frequent intraoperative hypotension (P <0.05). Postoperative respiratory complications were related to age, preoperative renal failure, neurological comorbidities, and bedridden state (P < 0.05). ICU admission was associated with the time from injury to operation, preoperative neurological comorbidities and frequent intraoperative hypotension (P < 0.05). Conclusions Adequate treatment of respiratory comorbidities and prevention of cardiovascular complications might be the critical factors in reducing postoperative mortality in elderly patients undergoing hip fracture surgery.

    Introduction There is a high incidence of blood transfusion following hip fractures in elderly patients. Tranexamic acid (TXA) has proven efficacy in decreasing blood loss in general trauma patients as well as patients undergoing elective orthopaedic surgery. A randomised controlled trial will measure the effect of TXA in a population of patients undergoing hip fracture surgery. Methods This is a double-blinded, randomised placebo-controlled trial. Patients admitted through the emergency room that are diagnosed with an intertrochanteric or femoral neck fracture will be eligible for enrolment and randomised to either treatment with 1 g of intravenous TXA or intravenous saline at the time of skin incision. Patients undergoing percutaneous intervention for non-displaced or minimally displaced femoral neck fractures will not be eligible for enrolment. Postoperative transfusion rates will be recorded and blood loss will be calculated from serial haematocrits. Ethics and dissemination This protocol was approved by the Institutional Review Board (IRB) and is registered with clinicaltrials.gov. The findings of the trial will be disseminated through peer-reviewed journals and conference presentations. Trial registration number NCT01940536. PMID:27329438

    Background Hip fracture affects more than 1.6 million persons worldwide and causes substantial changes in body composition, function, and strength. Usual care (UC) has not successfully restored function to most patients, and prior research has not identified an effective restorative program. Our objective was to determine whether a yearlong home-based exercise program initiated following UC could be administered to older patients with hip fracture and improve outcomes. Methods A randomized controlled trial of 180 community dwelling female patients with hip fracture, 65 years and older, randomly assigned to intervention (n=91) or UC (n=89). Patients were recruited within 15 days of fracture from 3 Baltimore-area hospitals from November 1998 through September 2004. Follow-up assessments were conducted at 2, 6, and 12 months after fracture. The Exercise Plus Program was administered by exercise trainers that included supervised and independently performed aerobic and resistive exercises with increasing intensity. Main outcome measures included bone mineral density of the contralateral femoral neck. Other outcomes included time spent and kilocalories expended in physical activity using the Yale Physical Activity Scale, muscle mass and strength, fat mass, activities of daily living, and physical and psychosocial functioning. The effect of intervention for each outcome was estimated by the difference in outcome trajectories 2 to 12 months after fracture. Results More than 80% of participants received trainer visits, with the majority receiving more than 3 quarters (79%) of protocol visits. The intervention group reported more time spent in exercise activity during follow-up (P<.05). Overall, small effect sizes of 0 to 0.2 standard deviations were seen for bone mineral density measures, and no significant patterns of time-specific between-group differences were observed for the remaining outcome measures.

    While increasing age, decreasing body mass index (BMI), and physical inactivity are known to increase hip fracture risk, whether these factors have similar effects on other common fractures is not well established. We used prospectively-collected data from a large cohort to examine the role of these factors on the risk of incident ankle, wrist and hip fractures in postmenopausal women. 1,155,304 postmenopausal participants in the Million Women Study with a mean age of 56.0 (SD 4.8) years, provided information about lifestyle, anthropometric, and reproductive factors at recruitment in 1996-2001. All participants were linked to National Health Service cause-specific hospital records for day-case or overnight admissions. During follow-up for an average of 8.3 years per woman, 6807 women had an incident ankle fracture, 9733 an incident wrist fracture, and 5267 an incident hip fracture. Adjusted absolute and relative risks (RRs) for incident ankle, wrist, and hip fractures were calculated using Cox regression models. Age-specific rates for wrist and hip fractures increased sharply with age, whereas rates for ankle fracture did not. Cumulative absolute risks from ages 50 to 84 years per 100 women were 2.5 (95%CI 2.2-2.8) for ankle fracture, 5.0 (95%CI 4.4-5.5) for wrist fracture, and 6.2 (95%CI 5.5-7.0) for hip fracture. Compared with lean women (BMI<20 kg/m(2)), obese women (BMI≥30 kg/m(2)) had a three-fold increased risk of ankle fracture (RR=3.07; 95%CI 2.53-3.74), but a substantially reduced risk of wrist fracture and especially of hip fracture (RR=0.57; 0.51-0.64 and 0.23; 0.21-0.27, respectively). Physical activity was associated with a reduced risk of hip fracture but was not associated with ankle or wrist fracture risk. Ankle, wrist and hip fractures are extremely common in postmenopausal women, but the associations with age, adiposity, and physical activity differ substantially between the three fracture sites.

    Objective: To derive a simple score for estimating the long-term risk of osteoporotic and hip fracture in individual patients with MS. Methods: Using the UK General Practice Research Database linked to the National Hospital Registry (1997–2008), we identified patients with incident MS (n = 5,494). They were matched 1:6 by year of birth, sex, and practice with patients without MS (control subjects). Cox proportional hazards models were used to calculate the long-term risk of osteoporotic and hip fracture. We fitted the regression model with general and specific risk factors, and the final Cox model was converted into integer risk scores. Results: In comparison with the FRAX calculator, our risk score contains several new risk factors that have been linked with fracture, which include MS, use of antidepressants, use of anticonvulsants, history of falling, and history of fatigue. We estimated the 5- and 10-year risks of osteoporotic and hip fracture in relation to the risk score. The C-statistic was moderate (0.67) for the prediction of osteoporotic fracture and excellent (0.89) for the prediction of hip fracture. Conclusion: This is the first clinical risk score for fracture risk estimation involving MS as a risk factor. PMID:22895583

    Objectives To evaluate potential sex differences and other factors associated with complications within 4 months after a hip fracture. Methods A total of 1,915 patients ≥65 years (480 men) with hip fracture were consecutively included in a prospective multicenter cohort study. A review of medical records and patient interviews according to a study protocol based on the Standardized Audit of Hip Fractures in Europe (SAHFE, RIKSHÖFT) was performed. Sex differences in comorbidity according to the American Society of Anesthesiologists score and complications 4 months after a hip fracture were registered. Multivariate logistic regression analysis was performed to identify factors related to complications. Results Male sex was associated with worse general health according to the American Society of Anesthesiologists classification (P=0.005) and with more comorbidities (P<0.001). Male sex emerged as a risk factor for developing pneumonia (P<0.001), and additionally, 18% of the men suffered from cardiac complications compared with 13% of the females (P=0.018). Female sex was predisposed for urinary tract infections, 30% vs 23% in males (P=0.001). Mortality was higher in the male vs female group, both within 30 days (15% vs 10%, P=0.001) and at 4 months (24% vs 14%, P=0.001). Conditions associated with pneumonia were male sex, pulmonary disease, and cognitive impairment. Cardiac complications were associated with delayed surgery and cardiovascular and pulmonary disease. Conclusion Before surgery, men with hip fracture already have a poorer health status and higher comorbidity rate than women, thus resulting in a twofold increased risk of pneumonia. Cognitive dysfunction and pulmonary disease contributed to pneumonia in men. Delayed surgery seems to increase the risk for cardiac complications. It is important to consider the sex perspective early on together with cardiopulmonary comorbidity and cognitive dysfunction to be able to counteract serious complications that may

    Hip fractures remain one of the most devastating injuries in the elderly. Early prediction of outcome following hip fracture potentially results in more efficient health care. The aims of this study were to explore predictors of ambulation status at hospital discharge in patients ≥65 years of age operated on for fracture of the hip, and to investigate the impact of ambulation status at hospital discharge on 1-year mortality after hip fracture. We studied 344 patients who underwent surgery for hip fracture during a 12 month period. Multivariate regression analysis was used to explore predictive factors for ambulatory status at discharge, and 1-year mortality adjusted on important baseline variables. Cumulative 1-year mortality was significantly lower for patients in the ambulatory group when compared to patients in the non-ambulatory group. Patients who were older, had severe cognitive impairment, lower functional level before injury, and in whom postoperative delirium and pressure ulcers occurred had a higher chance of not recovering their gait ability at hospital discharge, and being dead 1 year after hip fracture. Inability to walk at hospital discharge and presence of delirium are independent predictors of 1-year mortality. Every effort should be made to assure early mobilisation after hip fracture surgery, and prevention, prompt recognition and treatment of postoperative complications is important in order to facilitate better short-and long-term outcome.

    Objective To investigate the prognostic factors predicting the recovery of pre-fracture functional mobility, we evaluated this by the use of ambulatory assistive devices in short-term follow-up. Methods Five hundred and fifty-three elderly patients who had undergone hip fracture operations from January 2006 to June 2013 were enrolled in this retrospective study. Clinical characteristics and predicted factors affecting functional recovery, such as the delay of rehabilitation after the operation, were reviewed. The functional status of the gait was classified as either a bedridden state, wheelchair-bound state, walker gait, single cane gait, and self-gait without any ambulatory assistance device. When this functional grade in patients who recovered after the surgery was compared to before the surgery, this state was considered 'functional recovery'. Results One hundred and ninety-two patients (34.7%) showed recovery of preoperative mobility in the first month after their operation. Multiple logistic regression analysis identified that the following four factors were significantly associated with a deterioration of functional recovery: old age (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.92-0.97), delays in rehabilitation after operation (OR, 0.94; 95% CI, 0.89-0.98), the presence of cognitive dysfunction (OR, 0.36; 95% CI, 0.18-0.71), and trochanteric fracturing (OR, 0.58; 95% CI, 0.36-0.94). Conclusion We found that old age, cognitive dysfunction, trochanteric fracture type, and delay of rehabilitation were associated with the deterioration of functional recovery after a hip fracture operation in the short-term. Therefore, early rehabilitation was required to acquire functional recovery after a hip fracture operation in the short-term. PMID:25566483

    Squeaking has been reported after ceramic-on-ceramic total hip arthroplasty (THA), but its pathomechanics is not fully understood. Impaired lubrication is suspected to be the main reason. The management of patients impacted by this phenomenon is not well defined and, as it is not considered to be cause for alarm, revision is not strongly recommended. Here, we describe a ceramic insert fracture discovered during revision surgery performed to correct severe squeaking. Preoperative investigation (plain X-rays, ultrasound and computed tomography) did not reveal ceramic fracture or definite component malposition. To date, there are no other published cases of incidental discovery of a bearing component fracture during revision of ceramic-on-ceramic hip replacement due to squeaking. We believe that squeaking is not a trivial phenomenon and recommend careful management of patients suffering with this symptom. PMID:23911133

    Aim: To compare the efficacies of four surgical treatments, i.e., total hip arthroplasty (THA), internal fixation (IF), hemiarthroplasty (HA), and artificial femoral head replacement (artificial FHR), by performing a network meta-analysis based on Harris hip score (HHS) in elderly patients with femoral neck fracture. Methods: In strict accordance with specific inclusion and exclusion criteria, randomized controlled trails (RCTs) were screened and selected from a larger group of studies that were retrieved through a comprehensive search of scientific literature databases, further complimented by manual search. The resultant high-quality data from final selected studies were analyzed using Stata 12.0 software. Results: A total of 3680 studies were initially retrieved from database search, and 15 RCTs were eventually incorporated into this meta-analysis, containing 1781 elderly patients who had undergone various surgical treatments for femoral neck fracture (THA group = 604; HA group = 604; IF group = 495; artificial FHR group = 78). Our major result revealed a statistically significant difference in HHS of femoral neck fracture when HA and IF groups were compared with THA. No differences were detected in the HHS of femoral neck fracture undergoing artificial FHR and THA. The surface under the cumulative ranking curves (SUCRA) value of HHS, in elderly patients with femoral neck fracture after surgery, revealed that IF has the highest value. Conclusions: The current network meta-analysis results suggest that IF is the superlative surgical procedure for femoral neck fracture patients, and IF significantly improves the HHS in femoral neck fracture patients.

    Objective We examined the association between physical activity recorded by Actigraphy during therapy sessions (therapy) to therapist rated patient participation and self reported future functional outcomes. We hypothesized those participants who were more active during rehab would have higher participation scores and better functional outcomes following hip fracture compared to those who were less active. Design Longitudinal study with 3 and 6 month follow-up. Setting Participants were recruited from skilled nursing (SN) and inpatient rehabilitation (IR) facilities. Participants Participants included 18 community dwelling older adults admitted to SN or IR facilities after hip fracture. Participants were included if they were ≥ 60 years of age and ambulatory with or without assistance from a device or another person. Intervention Not Applicable Main Outcome Measure Physical activity was quantified during participants’ rehab using the Actigraph accelerometer worn consecutively over 5 days. The Pittsburgh Participation Rating Scale was used to quantify patient participation during their inpatient therapy sessions. Self reported functional outcomes were measured by the Hip Fracture Functional Recovery Scale (HFRS) at baseline, 3 and 6 months following fracture. Results Participants with higher Actigraphy counts during rehab were ranked by their therapists as having excellent participation compared to those who were less active. Participants who were more active reported better functional abilities at both 3 and 6 month time points and achieved 78% and 91% recovery of self reported pre-fracture function compared to those who were less active achieving 64% and 73% recovery. Conclusion Actigraphy provides an objective measure of physical activity exhibiting predictive validity for future functional outcomes and concurrent validity against patient participation in patients after hip fracture.

    Objective To predict ambulatory capacity, 1 month after physical therapy following hip fracture surgery. Methods A retrospective chart review was carried out. Patients more than 60 years old, who underwent hip fracture surgery and received physical therapies, were selected (n=548). Age, gender, presence of cognitive dysfunction, combined medical diseases, combined fractures, previous history of hip surgery, prefracture ambulatory capacity, days from the fracture to surgery, type of fracture, type of surgery, presence of postoperative complications, days from the surgery to physical therapy, and total admission period, were collected. Prefracture ambulatory capacity and postoperative ambulatory capacity were classified into non-ambulatory status (NA), ambulation with assistive device (AA), and independent-ambulation without any assistive device (IA). Multiple-logistic regression analysis was performed for the prediction of postoperative ambulatory capacity. Results Age (odds ratio [OR]=0.94 for IA and 0.96 for IA or AA), gender (OR=1.64 for IA and 0.98 for IA or AA), prefracture ambulatory capacity (OR of IA=19.17 for IA; OR of IA=16.72 for IA or AA; OR of AA=1.26 for IA, OR of AA=9.46 for IA or AA), and combined medical disease (OR=2.02) were found to be the factors related to postoperative ambulatory capacity and the prediction model was set up using these four factors. Conclusion Using this model, we can predict the ambulatory capacity following hip fracture surgery. Further prospective studies should be constructed to improve postoperative ambulatory capacity.

    BACKGROUND We have previously reported a gender difference in the occurrence of hip fracture type with age in our local population. In the current report, we have explored this phenomenon in a Canadian population using five years of data from a national administrative database. We have compared community-dwelling and institutionalized individuals to determine if frailty is important and has a differential effect on the type of hip fracture experienced. METHODS Hospitalization records from 2005 to 2009, in which the most responsible diagnosis, that is the diagnosis causing the admission to hospital, was a hip fracture, were obtained from the Discharge Abstract Database of the Canadian Institute for Health Information. Hip fracture type was identified using the Canadian Classification of Health Interventions and the International Classification of Diseases 10th Revision, Canada (ICD-10-CA). Hip fracture proportions were calculated for the study period and stratified by age group and sex. RESULTS The relative proportion of intertrochanteric fractures in women rose from 35% in the youngest group (55–59 years) to 51% in the oldest group (84+ years; P < 0.0001). In men, the proportions remain relatively stable (47% and 44%, respectively). Community and institutionalized patients showed the same pattern. CONCLUSIONS The change in the proportion of the two hip fracture types that occur in women but not men may point to differences in the etiology and consequently the approaches to prevention for the two fracture types. Level of frailty did not seem to be important. PMID:27158225

    We investigated geographic variations in Medicare spending for DRG 536 (hip and pelvis fracture). We identified 22,728 patients. The median number of charges, discharges, and payments were recorded. Hospitals were aggregated into core based statistical (CBS) areas and the coefficient of variation (CV) was calculated for each area. On average, hospitals charged 3.75 times more than they were reimbursed. Medicare charges and reimbursements demonstrated variability within each area. Geographic variation in Medicare spending for hip fractures is currently unexplained. It is imperative for orthopedists to understand drivers behind such high variability in hospital charges for management of hip and pelvis fractures. PMID:27408500

    2016-01-01

    Summary We evaluated healthcare utilization associated with treating different fracture types in over 51,000 women aged ≥55 years. Over the course of 1 year, there were five times more non-hip, non-spine fractures than hip or spine fractures, resulting in twice as many days of hospitalization and rehabilitation/nursing home care for non-hip, non-spine fractures. Purpose To evaluate the medical healthcare utilization associated with treating several types of fractures in women aged 55 years or older from various geographic regions. Methods Information from the Global Longitudinal study of Osteoporosis in Women (GLOW) was collected via self-administered patient questionnaires at baseline and year 1 (n=51,491). Self-reported clinically recognized low-trauma fractures at year 1 were classified as incident spine, hip, wrist/hand, arm/shoulder, pelvis, rib, leg, and other fractures. Healthcare utilization data were self-reported and included whether the fracture was treated at a doctor’s office/clinic or at a hospital. Patients were also asked if they had undergone surgery or been treated at a rehabilitation center or nursing home. Results Over the 1-year study period, there were 195 spine, 134 hip, and 1,654 non-hip, non-spine fractures. In the GLOW cohort, clinical vertebral fractures resulted in 617 days of hospitalization and 512 days of rehabilitation/nursing home care, while hip fractures accounted for 1,306 days of hospitalization and 1,650 days of rehabilitation/nursing home care. Of particular interest is the result that non-hip, non-spine fractures resulted in 3,805 days in hospital and 5,186 days of rehabilitation/nursing home care. Conclusions While hip and vertebral fractures are well recognized for their associated increase in health resource utilization, non-hip, non-spine fractures, by virtue of their 5-fold greater number, require significantly more healthcare resources.

    Atypical femoral fractures are stress or insufficient fractures induced by low energy trauma or no trauma and have specific X-ray findings. Although the American Society for Bone and Mineral Research has excluded periprosthetic fractures from the definition of an atypical femoral fracture in 2013, this is still a matter of controversy because some authors report periprosthetic fractures showing specific features of atypical fractures around a well-fixed femoral stem. We report 3 cases of periprosthetic femur fractures that had specific radiographic features of atypical femoral fractures in patients with a history of prolonged bisphosphonate use; we also review relevant literature.

    OBJECTIVE: Hip fractures have been associated with increased mortality in the elderly. Several risk factors such as the time between the insult and the surgical repair have been associated with hip fracture mortality. Nevertheless, the risk of delayed surgical repair remains controversial. Few studies have examined this issue in Brazil. The aim of this study was to study the risk factors for death one year after hip fracture and in-hospital stay at a tertiary hospital in South Brazil. METHODS: A prospective cohort study was carried out from April 2005 to April 2011 at a tertiary university hospital at Santa Maria, Brazil. Subjects admitted for hip fracture who were 65 years of age or older were followed for one year. Information about fracture type, age, gender, clinical comorbidities, time to surgery, discharge, and American Society of Anesthesiologists score were recorded. Death was evaluated during the hospital stay and at one year. RESULTS: Four hundred and eighteen subjects were included in the final analysis. Of these, 4.3% died in-hospital and 15.3% were dead at one year. Time to surgery, American Society of Anesthesiologists score, Ischemic Heart Disease, and in-hospital stay were associated with death at one year in the univariate analysis. The American Society of Anesthesiologists score and time to surgery were one-year mortality predictors in the final regression model. In-hospital death was associated with American Society of Anesthesiologists score and age. CONCLUSION: Time to surgery is worryingly high at the South Brazil tertiary public health center studied here. Surgical delay is a risk factor that has the potential to be modified to improve mortality. PMID:24714833

    Purpose This study was aimed to explore and report the short term results of primary cementless hip arthroplasty in treatment of unstable intertrochanteric femur fracture in elderlys. Materials and Methods Between March 2009 and Feburary 2012, 35 arthroplasty cases performed by single surgeon and followed up for more than one year were evaluated. They were 21 females and 14 males with mean age of 78 years (range, 71-92 years). Preoperative evaluation was performed by American Society of Anesthesia score. Retrospective evaluation was performed by operative time, transfusion amount, time to operation days, hospital stay and time to full weight bearing. Clinically, ambulatory ability was checked by Parker and Palmer (P&P) score and function of hip was appraised by Harris hip score (HSS). Radiologically, bone healing of fractured trochanteric fragment and presence of subsidence, stress shielding or osteolysis were checked. Results Fracture type was 11 cases of A2.2, 18 cases of A2.3 and 6 cases of A3.3. Femoral stems used were 8 cases of rectangular tapered wedge type and 27 cases of fluted modular distal fixation type. P&P score improved from mean preinjury score of 7.1 to mean postoperative last follow-up score of 6.5. Median HHS at last follow-up was 75. Mean time to full weight bearing was 47 days (24-79 days). Postoperative complications were one case of linear periprosthetic femoral fracture and one case of postoperative dislocation. Conclusion Cementless hip replacement arthroplasty could be a good option for unstable intertrochanteric femoral fracture in elderlys.

    The incidence of osteoporosis and associated fractures becomes an increasingly relevant issue for the public health institutions of industrialized nations. Fractures of the hip represent the worst complication of osteoporosis with a significantly elevated rate of mortality. Prediction of fracture risk is a major focus of osteoporosis research and, over the years, has been approched from different angles. There exist two distinct subtypes of transcervical and pertrochanteric hip fracture that can be distinguished on the basis of the anatomical location of the injury. While the epidemiology of hip fractures has been well described, typically, little or no distinction is made between the subtypes. The object of this study was to determine whether local topological texture properties based on the Minkowski Functionals (MF) obtained from standard radiographs of the proximal femur in patients with hip fracture can be used to differentiate between the two types of fracture pattern. The texture features were extracted from standardized regions of interest (femoral head, neck, and pertrochanteric region) in clinical radiographs of the hip obtained from 90 post-menopausal women (69.8 +/- 7.9 yrs). 30 of the women had sustained pertrochanteric fractures, 30 had transcervical hip fractures and 30 were age-matched controls. We determined an optimized topological parameter MF2Dloc using an integrative filtering procedure based on a sliding-windows algorithm. Statistical relationship between the fracture type (pertrochanteric/transcervical) and the value of MF2Dloc was assessed by receiver-operator characteristic (ROC) analysis. Depending on the anatomical location of the region of interest for texture analysis correct classification of tanscervial and pertrochanteric fractures ranged from AUC = 0.79 to 0.98. In conclusion, quantitative texture properties of trabecular bone extracted from radiographs of the hip can be used to identify patients with hip fracture and to distinguish

  2. Adherence to guidelines regarding total hip replacement for fractured neck of femur.

    Introduction In 2011 the National Institute for Health and Care Excellence (NICE) published guidelines suggesting that clinicians offer total hip replacement (THR) to patients with displaced intracapsular hip fractures who could walk independently outside with no aids or one stick, who are not cognitively impaired and are ASA (American Society of Anesthesiologists) grade ≤2. They also stated that best practice is operating within 36 hours of presentation. This audit aimed to determine whether Scarborough Hospital was following these guidelines and compared the results with the national average. Methods Two years of data (January 2012 - December 2013) were collected retrospectively from Scarborough Hospital's hip fracture database on all patients presenting with an intracapsular hip fracture. Data were analysed to determine whether patients who had a THR fulfilled NICE criteria. Furthermore, patients with hemiarthroplasties who were eligible for THRs were identified. Finally, the time to surgery was calculated to examine whether patients receiving THRs waited longer than patients receiving hemiarthroplasties. Results In 2012, 48.6% of all eligible patients received a THR while in 2013 the figure was 55.9%. These percentages are much higher than the national average. However, 36 (53.7%) of the 67 patients who received a THR did not fulfil all the NICE criteria, mainly owing to high ASA grade. The mean time from presentation to theatre for THR was 8 hours and 37 minutes longer for THR patients than for hemiarthroplasty in 2012. This difference was reduced to 2 hours and 12 minutes in 2013. Conclusions Small general hospitals can meet and even exceed the standards regarding treatment strategies for hip factures. However, there is still room for improvement. Departmental training may be useful in achieving this aim. The anaesthetic team should be involved at the earliest opportunity, to help optimise patients preoperatively and determine whether patients listed for

    Surgical dislocation of the hip in the treatment of acetabular fractures allows the femoral head to be safely displaced from the acetabulum. This permits full intra-articular acetabular and femoral inspection for the evaluation and potential treatment of cartilage lesions of the labrum and femoral head, reduction of the fracture under direct vision and avoidance of intra-articular penetration with hardware. We report 60 patients with selected types of acetabular fracture who were treated using this approach. Six were lost to follow-up and the remaining 54 were available for clinical and radiological review at a mean follow-up of 4.4 years (2 to 9). Substantial damage to the intra-articular cartilage was found in the anteromedial portion of the femoral head and the posterosuperior aspect of the acetabulum. Labral lesions were predominantly seen in the posterior acetabular area. Anatomical reduction was achieved in 50 hips (93%) which was considerably higher than that seen in previous reports. There were no cases of avascular necrosis. Four patients subsequently required total hip replacement. Good or excellent results were achieved in 44 hips (81.5%). The cumulative eight-year survivorship was 89.0% (95% confidence interval 84.5 to 94.1). Significant predictors of poor outcome were involvement of the acetabular dome and lesions of the femoral cartilage greater than grade 2. The functional mid-term results were better than those of previous reports. Surgical dislocation of the hip allows accurate reduction and a predictable mid-term outcome in the management of these difficult injuries without the risk of the development of avascular necrosis.

    Abstract We carried out the study to investigate and quantitatively assess the potential association between current level of physical activity and the risk of osteoporosis hip fracture in older women. Relevant publications before October 2015 were identified using the PubMed and Ovid searching tools. A dose–response meta-analysis was carried out to combine and analysis results. Fourteen prospective studies were included in the meta-analysis. A general analysis of 9 studies showed a significant inverse relationship between increasing level of physical activity and risk of hip fracture in older women [relative risk (RR) = 0.93, 95% confidence interval (95% CI): 0.91–0.96]. The result of a sensitivity analysis was consistent with the general analysis (RR = 0.94, 95% CI: 0.93–0.96). The association between increasing level of physical activity and risk of wrist fracture was not statistically significant in a general analysis of three studies (RR = 1.004, 95% CI: 0.98–1.03). A potential direct association between increasing level of physical activity and risk of wrist fracture was observed after removing 1 study with the greatest weight (RR = 1.01, 95% CI: 1.00–1.03). No significant publication bias was observed in our analysis. Our results show that increasing level of physical activity within an appropriate range may reduce the risk of hip fracture but not the risk of wrist fracture in older women. PMID:26986111

    Patient education about venous thromboembolism (VTE) prevention is needed to prevent complications and costly re-hospitalization. Nurses are uniquely positioned to provide vital education as patients transition from the inpatient setting to after discharge. Still, little is known about patient knowledge deficits and those of their caregivers. The purpose of this study was to explore VTE prevention knowledge in a sample of older hip fracture patients and family caregivers. At the time of hospital discharge, surveys were completed by hip fracture surgery patients (≥65; n=30) and family caregivers (n=30). Participants reported needs for more prophylactic anticoagulation and side effects education. Mean education satisfaction was 3.49 out of 5 among patients and 3.83 among caregivers. Focused patient education regarding the wisdom of VTE prevention, potential risks involved, and patient and care giver roles in advocating for better prevention measures is needed for these patients at risk for hospital readmission secondary to VTE.

    Dynamic hip screw fixation is a common orthopaedic procedure and to date, still can cause difficulties to the senior trauma surgeon. We present a case where an extra-capsular fracture of the proximal femur was managed with a dynamic hip screw (DHS) fixation. She proceeded to the operating theatre, where the fracture was stabilized with a 75-mm DHS and short-barrelled plate. The implant position was checked with intraoperative screening and the position accepted. Following attempted mobilization at 11 days post-operatively, the patient developed a recurrence of her preoperative pain. X-ray showed that the implant screw had separated from the barrel. Later scrutiny of the intraoperative screening films revealed that the barrel and screw were not engaged at the time of surgery. Intraoperative screening films should be carefully checked to ensure congruity of implant components. PMID:26136561

    To date, there has been little research into the clinical outcomes of total hip arthroplasty (THA) for intracapsular neck of femur (NOF) fracture in the very elderly. 44 patients over 75years underwent THA for an intracapsular NOF fracture over a two year period. Oxford Hip Scores were obtained from 37 patients with a mean score of 39.7 (range 11-47). Katz Index Scores were collected from 36 patients with a mean pre-operative score of 5.9 and post operative score of 5.7. THA in this population gives patients the best opportunity to return to premorbid function. When complications occur there is a catastrophic effect on independence. Therefore it is important to select these patients' appropriately and to optimise their medical condition peri-operatively. PMID:25311164

    The objective of this study is to compare percutaneous compression plating (PCCP) device with standard gamma nail (GN). A sample was prospectively followed and compared to a historical cohort: 82 intertrochanteric hip fractures in 81 patients treated with PCCP in 2004 versus 51 hip fractures treated with GN in 2003 (AO type 31A1, 31 A2). The main outcome measures were: surgery times, blood loss (Hb serum level and transfusions), complication, costs, for a 1-year follow-up. The minimally invasive PCCP technique resulted in a lower blood loss and consequently lower transfusion need (statistically significant), fewer implant-related complications and comparable surgery times. Overall surgical costs were lower for a comparable outcome in terms of healing and surgical time. PMID:18427918

    The treatment of hip fractures in the elderly represents a major public health priority and a source of ongoing debate among orthopaedic surgeons and anesthesiologists. Most of these injuries are treated with surgery in an expedient fashion. From the surgical perspective, there are certain special considerations in this population including osteoporosis, pre-existing arthritis, age, activity level, and overall health that contribute to the type of surgical fixation performed. Open reduction and internal fixation versus arthroplasty remain the two major categories of treatment. While the indications and treatment algorithms still remain controversial, the overall goal for these patients is early mobilization and prevention of morbidity and mortality. The use of preoperative, regional anesthesia has aided in this effort. The purpose of this review article is to examine the various treatment modalities for hip fractures in the elderly and discuss the most recent evidence in the face of a rapidly aging population.

    Background Intertrochanteric fractures are one of the most common fractures encountered in our practice. Most of them need operative intervention and union is achieved. As per the literature dynamic hip screw (DHS) is the gold standard for the treatment of these fractures, however problem arises with maintenance of neck shaft angle and proper reduction in unstable intertrochanteric fractures. The situation gets more complex when “cut out” of femoral head screw occurs either alone or in combination with varus collapse when they are treated with DHS. Here we are giving results of unstable intertrochanteric fractures treated with Proximal Femoral Locked Compression Plate (PFLCP) as compared with similar patients treated with Dynamic Hip Screw (DHS). Materials and Methods The study included a total of 27 patients (17 males, 10 females) with unstable intertrochanteric fractures who were subjected to PFLCP treatment from March 2011 to November 2012 in one group. Another was a similar group of 35 patients treated with DHS from March 2008 to February 2010. Results of group 1 were compared with group 2. Detailed clinical conditions of all patients, duration of surgery, blood loss, length of incision and duration of image intensifier use were recorded. Patients were revisited at 6 weeks, 3 months, 6 months and 1 year after operation. Results were evaluated clinically by Harris hip Score and radiologically for fracture union. Progress of union and complications (limb shortening, varus collapse, cut out of femoral head screw and medialization of distal fragment) were recorded. Results Among 27 patients treated with PFLCP, one patient expired 6 week postoperatively and one patient lost to follow up, so 25 patients were evaluated for final outcome of which 23 (92%) showed union at follow up of 12 months. One patient developed bending of proximal screws and three developed varus collapse. Among the group treated with DHS, eight patients developed varus collapse, seven

    INTRODUCTION In an elective setting, surgery is best avoided for at least 6 months following myocardial infarction. However, in the presence of a femoral neck fracture, this would most probably lead to significant complications in relation to prolonged immobilisation. There is no published mortality data for patients undergoing surgery for hip fracture following a recent myocardial infarction. The aim of this retrospective study was to assess the mortality of hip fracture patients with a recent myocardial infarction that have undergone surgery at our institution. PATIENTS AND METHODS Between January 2003 and October 2005, 2270 patients were admitted to our unit with a proximal femoral fracture. Of these, 11 patients were found to have a recent myocardial infarction. RESULTS Of these 11 patients, 8 were female. The average age was 78.2 years (range, 59–90 years). Average delay from the time of infarction to operation was 11.2 days (range, 3–23 days). Mortality at 1 and 6 months was 45.4% and 63.5%, respectively. DISCUSSION This is much higher than the overall reported mortality following proximal femur fracture. This information may be useful when planning future peri-operative care and discussing overall prognosis with patients and their relatives. PMID:17688728

    The aim of this study was to assess the home care needs and task difficulty of community-dwelling aged hip fracture and the association of functional recovery with care received. A cohort of hip fracture patients admitted to orthopedic wards for surgery was collected from August 2009 to December 2010. Patients transferred to long-term care facilities after surgery were excluded. Functional status (feeding, clothing, grooming, bathing, getting in/out of bed, walking, toileting, standing up/sitting down, and walking up/down stairs) and task difficulty for caregivers were recorded at discharge, one week and one month after discharge. In total, 116 patients (mean age: 79.4 ± 8.5 years, 51.7% males) were enrolled. The mean age of primary caregivers was 53.4 ± 14.2 years, and most were daughters or sons (54.3%), spouses (34.5%) or foreign workers (11.0%). The most common care needs were wound care (95.7%), medical visits (94.8%), cleaning and maintaining living quarters (92.2%) and vigilance to ensure patient safety (92.2%). The care needs and task difficulty significantly correlated with physical function before, one week and one month after discharge (r=-0.530, p<0.001; r=-0.326, p=0.001; r=-0.432, p<0.001; r=-0.684, p<0.001; and r=-0.475, p<0.001, respectively). The complex and taxing home care needs of community-dwelling elderly hip fracture patients were significantly associated with functional recovery. Comprehensive geriatric assessment and related special medical services may greatly help caregivers and promote the practice of aging in place. Further study is needed to develop appropriate caregiver education to promote the functional recovery of elderly hip fracture patients at home. PMID:23746577

    Management of high-risk hip fracture patients is complicated. The optimal surgical decision must be individualized and made promptly, with the assistance of all important team members, including primary care doctors, patient, family, and the orthopedic team. The risks of delaying surgery are significant and should be avoided if possible. Strategies for improving outcomes in these patients include collaborations with medicine and delirium prevention protocols, especially with early ambulation. PMID:19685643

    Background and purpose — There is continuing confusion among practitioners with regard to the optimal choice of anesthetic type for repair of hip fractures. We investigated whether type of anesthetic was associated with short-term mortality after hip fracture surgery. Patients and methods — We conducted a retrospective cohort study of patients with surgically treated hip fractures, performed between January 1, 2009 and December 31, 2012. Exposure of interest was anesthesia type (general, spinal/neuroaxial, and mixed). Endpoints were 30-, 90-, and 365-day post-surgery mortality. Multivariable conditional logistic regression models were used and odds ratios (ORs) and 95% confidence intervals (CIs) are reported. Results — Of the 7,585 participants, 5,412 (71%) were women and the median age was 80 (IQR: 72–85) years old. Of the total cohort, 4,257 (56%) received general anesthesia, 3,059 (40%) received spinal/neuroaxial, and 269 (4%) received mixed anesthesia. Overall, the incidence of 30-, 90-, and 365-day mortality was 4% (n = 307), 8% (n = 583), and 15% (n = 1,126), respectively. When compared with general anesthesia, the 365-day odds of mortality was marginally lower in patients with spinal/neuroaxial anesthesia (OR = 0.84, CI: 0.70–1.0), but it was similar in patients with mixed anesthesia (OR = 1.3, CI: 0.70–2.3). No other statistically significant differences were observed. Interpretation — Regarding mortality, this study does not support specific recommendations regarding the type of anesthetic in surgery of fractured hips. PMID:26986550

    Best practice tariff (BPT) was introduced as a financial incentive model to improve compliance with evidence-based care, such as operation for hip fracture within 36 hours of admission. We previously evaluated the impact of warfarin on patients with hip fracture, revealing significant delay to operation and subsequent loss of revenue. As a result of this, an "early trigger" intravenous vitamin K (IVK) pathway was introduced and the service reaudited a year later. The first cycle was a retrospective audit of all cases with hip fracture against BPT standards over a 32-month period. Subsequent protocol change resulted in all warfarinised cases being given 2 mg IVK in the emergency department prior to blood testing. This protocol was reaudited against the same BPT standards 12 months later. An intention-to-treat approach was used, despite breaches of protocol and other reasons for patients not progressing to theater. The data were analyzed with parametric tools to establish true clinical and statistical impact of the introduction of the protocol. In the first cycle, 80 patients were admitted on warfarin with a mean time to theater of 53.71 hours. Of these patients, 79% breached BPT due to anticoagulation. Twelve months following protocol introduction, 42 patients had a mean time to theater of 37.61 hours. Of these patients, 34% breached BPT due to anticoagulation. These data are both clinically and statistically significant (P < .001). No adverse events occurred. We have shown for the first time that "early-trigger" IVK can reduce delay to theater and maximize tariff payments in warfarinised patients with hip fracture. This is in addition to other established benefits associated with early surgery such as decreasing risk of pressure lesions and pneumonia. It affords high-quality patient-centered care while ensuring trauma units achieve maximal financial reimbursement through pay for improved performance and supports a culture of change behavior.

    Outcomes from patients suffering hip fracture remain poor, with 9% mortality at 30 days and 35% at 1 year. Despite robust guidelines these mortality rates have undergone little change. Admission serum lactate in patients with sepsis or suffering general trauma has been shown to be an indicator of adverse clinical outcomes. We investigated whether venous lactate can predict mortality for hip fracture patients. Over a 12-month period the admission venous lactate of all patients presenting to our institution with hip fractures was prospectively collated. Demographic and patient survivorship data were also prospectively recorded. Multivariate binary logistic regression and Cox proportional hazards ratio analysis was used to evaluate the relationship between admission venous lactate and 30-day mortality and early survivorship, whilst adjusting for age and gender. 770 patients were included in the study. The mean age was 80 years. The overall 30-day mortality for this cohort was 9.5%. Admission venous lactate was associated with early death. A 1mmol/L increase in venous lactate resulted in a 1.9 (95% CI 1.5-2.3 p<0.0001) fold increase in the odds of 30-day mortality and a 1.4 (95% CI: 1.2-1.6 p<0.0001) factor increase in the risk of death at any time after hip fracture. Admission venous lactate remained a predictor of mortality despite adjustment for patients American Society of Anesthesiologists (ASA) grade. Those with an admission serum lactate of 3mmol/L or greater were particularly at risk. This cohort had a 30-day mortality odds that was 5-fold higher than those whose level was less than 3mmol/L (p<0.0001) and at any-time risk of death that was 1.9 times higher (p<0.0001). Those with a level of less than 3mmol/L had a 30-day mortality of 6.8%. For those with an admission venous lactate of 3mmol/L or greater this was four times higher at 28%. The difference was statistically significant (p<0.0001). Elevated admission venous lactate following hip fracture is a

    Previous fracture is a well-documented risk factor for future fracture. The aim of this study was to quantify this risk on an international basis and to explore the relationship of this risk with age, sex, and bone mineral density (BMD). We studied 15259 men and 44902 women from 11 cohorts comprising EVOS/EPOS, OFELY, CaMos, Rochester, Sheffield, Rotterdam, Kuopio, DOES, Hiroshima, and two cohorts from Gothenburg. Cohorts were followed for a total of 250000 person-years. The effect of a prior history of fracture on the risk of any fracture, any osteoporotic fracture, and hip fracture alone was examined using a Poisson model for each sex from each cohort. Covariates examined were age, sex, and BMD. The results of the different studies were merged by using the weighted beta-coefficients. A previous fracture history was associated with a significantly increased risk of any fracture compared with individuals without a prior fracture (RR = 1.86; 95% CI = 1.75-1.98). The risk ratio was similar for the outcome of osteoporotic fracture or for hip fracture. There was no significant difference in risk ratio between men and women. Risk ratio (RR) was marginally downward adjusted when account was taken of BMD. Low BMD explained a minority of the risk for any fracture (8%) and for hip fracture (22%). The risk ratio was stable with age except in the case of hip fracture outcome where the risk ratio decreased significantly with age. We conclude that previous history of fracture confers an increased risk of fracture of substantial importance beyond that explained by measurement of BMD. Its validation on an international basis permits the use of this risk factor in case finding strategies. PMID:15268886

    Delirium is a common and potentially devastating problem for older patients following hip fracture. Although early detection is recommended, description and evaluation of standardized approaches are scarce. The aims of this quality improvement project were to: (1) implement a clinical algorithm for improving delirium detection and management and (2) assess the impact of the clinical algorithm on length of stay, discharge disposition and patient satisfaction. The pilot study was implemented on an orthopedic unit to evaluate the effectiveness of a clinical protocol for delirium detection and management to improve outcomes. Outcomes of 33 elderly post-operative hip fracture patients were compared to historical controls from the same unit. Delirium was detected in 18% of patients. Length of stay was reduced by 22% (P < .001), discharge disposition showed a 13% improvement (P = .17) and patient satisfaction scores showed a 15% (P = .15) improvement post-intervention. Implementation of a clinical algorithm to promote early detection and treatment of delirium in post-operative hip fracture patients is feasible and associated with improved outcomes. PMID:26547684

    Introduction Internal fixation of undisplaced intracapsular femoral neck fractures with cannulated hip screws is a widely accepted surgical technique, despite reported failure rates of 12%-19%. This study determined whether preoperative serum albumin levels are linked to fixation failure. Methods We retrospectively reviewed 251 consecutive undisplaced intracapsular femoral neck fracture patients treated with cannulated hip screws in a district general hospital. Preoperative albumin levels were measured, and the fixation technique, classification and posterior tilt on radiography assessed. Fixation failure was defined as a screw cut, avascular necrosis (AVN) or non-union. Results Of the patients, 185 were female and 66 male. The mean age was 77 years (range 60-101 years). Thirty seven (15%) patients had fixation failure: 10 (4%) due to AVN; 12 (5%) due to non-union; and 15 (6%) due to fixation collapse. Low serum albumin levels were significantly associated with failure (p=0.01), whereas gender (p=0.56), operated side (p=0.62), age (p=0.34) and screw configuration (p=0.42) were not. A posterior tilt angle greater than 20° on lateral radiography significantly predicted failure (p=0.002). Conclusions Preoperative serum albumin is an independent predictor of cannulated hip screw fixation failure in undisplaced femoral neck fractures. Nutritional status should therefore be considered when deciding between surgical fixation and arthroplasty to avoid the possibility of revision surgery, along with an increased risk of morbidity and mortality.

    Patients with hip fractures are older and often present many co-morbidities, including dementia. These patients cannot answer quality of life questionnaires and are generally excluded from trials. We hypothesized that a significant number of patients are being excluded from these studies and this may impact outcomes. This was a two part study; the first analyzing databases of two ongoing large-scale multi-centred hip fracture trials and the second being a systematic review. The FAITH and HEALTH studies were analyzed for exclusion incidence directly related to dementia. The second part consisted of a systematic search of all relevant studies within the last 20 years. In the FAITH study, a total of 1690 subjects were excluded, 375 (22.2%) of which were due to dementia or cognitive impairment. In the HEALTH study, 575 were excluded with dementia/cognitive impairment representing 207 patients (36%). Following the systematic review, 251 articles were identified 17 of which were retained. The overall prevalence of dementia was 27.9% (range 2-51%). Only two studies compared demented and non-demented groups. In these studies significant increases in both mortality and complications were found. In summary, when investigating hip fractures, choosing appropriate objective endpoints is essential to ensure results are also applicable to patients with dementia. PMID:22999009

    Background. Residual neuromuscular block (NMB) after general anesthesia has been associated with pulmonary dysfunction and hypoxia, which are both associated with postoperative delirium (POD). We evaluated the effects of sugammadex on POD in elderly patients who underwent hip fracture surgery. Methods. Medical records of 174 consecutive patients who underwent hip fracture surgery with general anesthesia were reviewed retrospectively to compare the perioperative incidence of POD, pulmonary complications, time to extubation, incidence of hypoxia, and laboratory findings between patients treated with sugammadex and those treated with a conventional cholinesterase inhibitor. Results. The incidence of POD was not significantly different between the two groups (33.3% versus 36.5%, resp.; P = 0.750). Postoperative pulmonary complications and laboratory findings did not showed significant intergroup difference. However, time to extubation (6 ± 3 versus 8 ± 3 min; P < 0.001) and the frequency of postoperative hypoxia were significantly lower (23% versus 43%; P = 0.010) in the sugammadex group than in the conventional cholinesterase inhibitor group. Conclusion. Sugammadex did not reduce POD or pulmonary complications compared to conventional cholinesterase inhibitors, despite reducing time to extubation and postoperative hypoxia in elderly patients who underwent hip fracture surgery under general anesthesia.

    In this study, we aimed to compare the effect of general versus regional anesthesia on postoperative outcomes in patients undergoing surgical repair of hip fracture. Randomized controlled trials, prospective studies and retrospective observational studies were searched in PubMed, Medline and Embase database published between January 2005 and March 2014. The overall outcome was measured by odds ratios (ORs) and risk ratios (RRs) with their corresponding 95% confidence intervals (CIs). A total of 7 trials, involving 36448 patients received general anesthesia and 33952 patients received regional anesthesia, were included in present meta-analysis. We found that the 30-day mortality rate was lower in general anesthesia cases than that in regional cases (5.3% vs. 6.3%). Overall, our results demonstrated that there was no significant difference in 30-day mortality between two types of anesthesia in patients with hip fracture surgery (RR=0.98, 95% CI=0.92-1.04, P=0.48), indicating that types of anesthesia might not be a risk factor for hip fracture surgery. No statistically significant difference was observed in other outcome measures (P>0.05). In conclusion, our results suggested that the choice of anesthesia (general or regional) should be made by the anesthesiologist on an individual basis and based on the patient’s medical conditions. Further research is still needed to evaluate the effect of these two anesthesia methods. PMID:26884943
