Abstract
BACKGROUND Hip fractures constitute a major public health problem for older individuals. They are associated with functional deterioration, limited mobility, and increased mortality, while contributing to economic and social hardships that are compounded by a second hip fracture. With the aging US population and increasing rates of hip fractures, it is essential to understand factors surrounding subsequent contralateral hip fractures. MATERIALS AND METHODS This descriptive study was a retrospective review of patients 60 years and older who were identified in the institutional geriatric hip fracture database as having had an initial and subsequent contra-lateral hip fracture, with the second treated at our tertiary referral center. RESULTS The incidence of subsequent hip fracture was 13.2%. The mean time to second hip fracture was 3.5 years after the initial injury. The first fracture tended to be a femoral neck fracture, whereas the second injury was more likely to have an intertrochanteric pattern. There was a higher complication rate after a subsequent hip fracture. Patients taking osteoporosis and adjuvant medication prior to admission for the second fracture tended to have a lower 90-day mortality rate. Patients with a history of any fracture prior to the first hip fracture, with cancer, and with osteopenia had shorter intervals to the subsequent event. CONCLUSION Subsequent hip fractures carry high morbidity and mortality rates. Steps should be taken after the initial injury to optimize outcomes in the case of a subsequent event. Patients discharged after initial hip fracture should be maintained with osteoporosis medication. [Orthopedics. 202x;4x(x):xx-xx.].

Relationship between meteorological variations, seasonal influenza, and hip fractures in the elderly: A modelling investigation using 22-year data. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 862:160764. [PMID: 36513237 DOI: 10.1016/j.scitotenv.2022.160764] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 11/17/2022] [Accepted: 12/04/2022] [Indexed: 06/17/2023]
Abstract
With the heavy negative health effect and economic burden of hip fractures in the elderly, the relationship of hip fractures with climate and seasonal influenza has not been quantified explicitly. In this study, we aim to make use of population-based data to evaluate the impact of meteorological factors and influenza activity on the hip fracture admissions for the elderly in Hong Kong from 1998 to 2019. Weekly numbers of admissions for the elderly due to hip fractures were used as the study outcome, and were matched with the meteorological factors included air temperature, relative humidity, solar radiation, and total rainfall. Strain-specific influenza-like illness-positive (ILI+) rates were employed as proxies for seasonal influenza activity. Quasi-Poisson generalized additive model in conjunction with distributed-lag non-linear model was used to elucidate the association of interest. According to the results, a total of 191,680 hip fracture admissions for the elderly aged ≥65 years were recorded over a 22-year span. The cumulative adjusted relative risks of hip fracture were 1.35 (95 % CI, 1.26-1.44) at the 5th percentile (15.05 °C) of air temperature, and 1.06 (95 % CI, 1.02-1.10) at the 95th percentile (20.91 MJ/m2) of solar radiation, with the reference value set to their respective medians. ILI+ rates were not associated with the risk of hip fracture. In the stratified analyses, a stronger association between cold condition and hip fracture was observed in males. Based on the results, strategies for preventing hip fractures with a focus on behaviors under unfavorable weather conditions should be targeted at individuals at risk.

The efficacy of femoral augmentation for hip fracture prevention using ceramic-based cements: A preliminary experimentally-driven finite element investigation. Front Bioeng Biotechnol 2023; 11:1079644. [PMID: 36777252 PMCID: PMC9909544 DOI: 10.3389/fbioe.2023.1079644] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Accepted: 01/06/2023] [Indexed: 01/27/2023] Open
Abstract
Femoral fractures due to sideways falls continue to be a major cause of concern for the elderly. Existing approaches for the prevention of these injuries have limited efficacy. Prophylactic femoral augmentation systems, particularly those involving the injection of ceramic-based bone cements, are gaining more attention as a potential alternative preventative approach. We evaluated the mechanical effectiveness of three variations of a bone cement injection pattern (basic ellipsoid, hollow ellipsoid, small ellipsoid) utilizing finite element simulations of sideways fall impacts. The basic augmentation pattern was tested with both high- and low-strength ceramic-based cements. The cement patterns were added to the finite element models (FEMs) of five cadaveric femurs, which were then subject to simulated sideways falls at seven impact velocities ranging from 1.0 m/s to 4.0 m/s. Peak impact forces and peak acetabular forces were examined, and failure was evaluated using a strain-based criterion. We found that the basic HA ellipsoid provided the highest increases in both the force at the acetabulum of the impacted femur ("acetabular force", 55.0% ± 22.0%) and at the force plate ("impact force", 37.4% ± 15.8%). Changing the cement to a weaker material, brushite, resulted in reduced strengthening of the femur (45.2% ± 19.4% acetabular and 30.4% ± 13.0% impact). Using a hollow version of the ellipsoid appeared to have no effect on the fracture outcome and only a minor effect on the other metrics (54.1% ± 22.3% acetabular force increase and 35.3% ± 16.0% impact force increase). However, when the outer two layers of the ellipsoid were removed (small ellipsoid), the force increases that were achieved were only 9.8% ± 5.5% acetabular force and 8.2% ± 4.1% impact force. These results demonstrate the importance of supporting the femoral neck cortex to prevent femoral fractures in a sideways fall, and provide plausible options for prophylactic femoral augmentation. As this is a preliminary study, the surgical technique, the possible effects of trabecular bone damage during the augmentation process, and the effect on the blood supply to the femoral head must be assessed further.

Abstract
Fragility fractures represent a growing global problem, including in the United Kingdom and European countries. Reports demonstrate the benefits of national guidance and organized fragility fracture programs through fracture liaison services to deliver care to patients who sustain these injuries. The challenge of assembling multidisciplinary teams, providing routine screening of appropriate patients, and monitoring therapies where there is a known compliance problem, remains an obstacle to the success of fragility fracture treatment programs to all. Efforts should continue to introduce and maintain fracture liaison services through coordinated national approaches and advanced systems.

Hip fracture predicts subsequent hip fracture: a retrospective observational study to support a call to early hip fracture prevention efforts in post-fracture patients. Osteoporos Int 2022; 33:113-122. [PMID: 34379148 PMCID: PMC8354846 DOI: 10.1007/s00198-021-06080-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Accepted: 07/20/2021] [Indexed: 01/06/2023]
Abstract
In this real-world retrospective cohort, subsequent hip fracture occurred in one in four patients with any initial fracture, most often after hip fracture, on average within 1.5 years. These data support the need for early post-fracture interventions to help reduce imminent hip fracture risk and high societal and humanistic costs. PURPOSE This large retrospective cohort study aimed to provide hip fracture data, in the context of other fractures, to help inform efforts related to hip fracture prevention focusing on post-fracture patients. METHODS A cohort of 115,776 patients (72.3% female) aged > 65 (median age 81) with an index fracture occurring at skeletal sites related to age-related bone loss between January 1, 2011, and March 31, 2015, was identified using health services data from Ontario, Canada, and followed until March 31, 2017. RESULTS Hip fracture was the most common second fracture (27.8%), occurring in ≥ 19% of cases after each index fracture site and most frequently (33.0%) after hip index fracture. Median time to a second fracture of the hip was ~ 1.5 years post-index event. Patients with index hip fracture contributed the most to fracture-related initial surgeries (64.1%) and post-surgery complications (71.9%) and had the second-highest total mean healthcare cost per patient in the first year after index fracture ($62,793 ± 44,438). One-year mortality (any cause) after index hip fracture was 26.2% vs. 15.9% in the entire cohort, and 25.9% after second hip fracture. CONCLUSION A second fracture at the hip was observed in one in four patients after any index fracture and in one in three patients with an index hip fracture, on average within 1.5 years. Index hip fracture was associated with high mortality and post-surgery complication rates and healthcare costs relative to other fractures. These data support focusing on early hip fracture prevention efforts in post-fracture patients.

Abstract
Objectives This study aims to develop a screening tool that will help first responders identify patients with proximal femur fractures, commonly referred to as hip fractures, on site and direct these patients to hospitals with orthopaedic surgery services. Study Design Prospective survey. Methods Literature and expert opinion defined parameters for the Collingwood Hip Fracture Rule (CHFR) which predict a patient's likelihood of hip fracture. The study population included adults presenting to Collingwood General and Marine Hospital with lower extremity injuries between December 1, 2019 and March 10, 2020. Excluded patients had previous hip replacement, previous hip fracture on the side of the injury, or a high energy mechanism of injury. Patients were assessed with the CHFR before receiving x-ray imaging. The parameters were scored based on their predictive powers and analyzed by a receiver operating characteristic curve. Results The study included 101 patients (mean age 66.3 years), and 25.7% had a hip fracture confirmed on imaging. The sensitivity, specificity, positive predictive value, and negative predictive value helped score each parameter. Factors receiving 1 point are: age 65 to 79 years, female, mechanical fall, unable to weight-bear, knee pain. Factors receiving 2 points are: bruising at greater trochanter, age >80 years. Factors receiving 3 points are: pain with hip rotation, leg shortened and externally rotated. Score is the summation of all the factors' points. The receiver operating characteristic curve (0.953; P value < .0001) demonstrated scores of 7 had sensitivity:specificity of 84.6%:94.7%. Conclusion The CHFR screening tool score of 7 can be used by first responders in the prehospital setting to identify patients who sustain a hip fracture and make appropriate triage decisions. This will improve patient outcomes and decrease institutional costs.

Abstract
Background Proximal femur fracture (PFF) carries significant morbidity, mortality, and cost implications to the health system. Subsequent contralateral fracture further decreases patient performance and increases the healthcare burden. This study aimed to identify and evaluate potential risk factors for consecutive PFF. Methodology Pilgrim Hospital PFF database from 2012 to 2019 was retrospectively analyzed. Patients over 60 years with low-energy fractures were included. Pathological and atypical fractures and polytrauma were excluded. Results There were 114 patients (4.18%) with contralateral hip fractures out of a total of 2727 PFF patients; 80% were females. The mean age was 82 years for the first hip fracture and 85 years for the second. The average time interval between fractures was 36 months. The fracture pattern was the same on both sides in 74.3% of patients (P<0.0001). Out of 53 patients with cemented hip hemiarthroplasty (CHH) on one side, 31 patients (59%) had a second CHH for the contralateral side. Likewise, out of 48 patients who had dynamic hip screw fixation during the first admission, 33 patients (69%) had the same procedure on the contralateral side too. During the two consecutive admissions, the length of hospital stay was not significantly different (P=0.30), median American Society of Anesthesiologists (ASA) grades were 3, hyponatremia increased from 25% to 29% (P=0.5), mean decline in abbreviated mental test score (AMTS) was 0.4, deterioration of Clinical Frailty Score and Charlson morbidity index were from 4.5 to 5.9 (P<0.0001), and from 5.4 to 6.1, respectively, and institutional residency was increased from 23 to 46 (P>0.0014). Conclusion The similarity of fracture pattern bilaterally requiring similar surgical procedures is comparable with other literature. Even though there is minimal or no change in the ASA, AMTS, and hospital stay between the two admissions, there is a significant decline in clinical frailty, mobility status, and an increase in residential dependency following a subsequent fracture. Our findings demonstrate the importance of emphasizing secondary preventive measures to prevent a consecutive fracture.

Prophylactic augmentation implants in the proximal femur for hip fracture prevention: An in silico investigation of simulated sideways fall impacts. J Mech Behav Biomed Mater 2021; 126:104957.

Abstract
Femoral fractures from sideways falls in the elderly are associated with significant rates of morbidity and mortality. Approaches to prevent these catastrophic injuries include pharmacological treatments, which have limited efficacy. Prophylactic femoral augmentation systems are a promising alternative that are gaining prominence by addressing the most debilitating osteoporosis-related fracture. We have developed finite element models (FEMs) of a novel experimental sideways fall simulator for cadavers. By virtue of the range of specimens and injury outcomes, these FEMs are well-suited to the evaluation of such implants. The purpose of this study was to use the FEMs to evaluate the mechanical effectiveness of three different prophylactic femoral augmentation systems. Models of the Y-Strut® (Hyprevention®, Pessac, France), Gamma Nail® (Stryker, Kalamazoo, USA), and a simple lag screw femoral fracture implant systems were placed into FEMs of five cadaveric pelvis-femur constructs embedded in a soft tissue surrogate, which were then subject to simulated sideways falls at seven impact velocities. Femur-only FEMs were also evaluated. Peak impact forces and peak acetabular forces were examined, and failure was evaluated using a strain-based criterion. We found that the femoral augmentation systems increased the peak forces prior to fracture, but were unable to prevent fracture for severe impacts. The Gamma Nail® system consistently produced the largest strength increases relative to the unaugmented femur for all five specimens in both the pendulum-drop FEMs and the femur-only simulations. In some cases, the same implant appeared to cause fractures in the acetabulum. The femur-only FEMs showed larger force increases than the pendulum-drop simulations, which suggests that the results of the femur-only simulations may not represent sideways falls as accurately as the soft tissue-embedded pendulum-drop simulations. The results from this study demonstrate the ability to simulate a high energy phenomenon and the effect of implants in an in silico environment. The results also suggest that implants could increase the force applied to the proximal femur during impact. Fracture outcomes from the tested implants can be used to inform the design of future devices, which reaffirms the value of modelling with biofidelic considerations in the implant design process. To the authors' knowledge, this is the first paper to use more complex biofidelic FEMs to assess prophylactic femoral augmentation methods.

Abstract
Introduction Hip fractures are a significant cause of morbidity and mortality in the elderly and are also associated with increased healthcare costs. A second contralateral hip fracture can lead to even more complications and healthcare costs. A significant proportion of the Irish hip fracture population does not receive a bone health assessment or falls specialist assessment to reduce the risk of future falls and fractures. This study aimed to analyze the incidence of a non-simultaneous contralateral hip fracture in an Irish population. Methods We retrospectively analyzed 1,344 patients presenting to our institution with a hip fracture from January 2007 to June 2019. Patients aged ≥ 60 years old presenting with a neck of femur or pertrochanteric fracture were included in our study. We excluded patients who had sub-trochanteric and femoral shaft fractures, high energy fractures, and pathological fractures. We also excluded patients less than 60 years old, as fractures in these younger patients may not be purely related to osteoporosis. Results A total of 1,099 hip fractures meeting the inclusion criteria were treated at our unit during the designated time period. A total of 102 (9.3%) patients experienced a second hip fracture. The mean age at first presentation in our institution was 78.5 years old, with a mean time between first and second hip fractures of 37.2 months. Conclusions Patients presenting with a second hip fracture may represent 9.3% of the Irish hip fracture population. We hope that this study will help inform on the rate of second hip fractures in an Irish population and help advocate for improved resources and implementation of secondary prevention strategies.

Abstract
BACKGROUND Hip fracture is a public health concern because of its considerable morbidity, excess mortality, great risk of disability, and high societal healthcare costs. China has the largest population of older people in the world and is experiencing rapid population aging and facing great challenges from an increasing number of hip fractures. However, few studies reported the epidemiology, especially at a national level. We aimed to evaluate trends in hip fracture incidence and associated costs for hospitalization in China. METHODS AND FINDINGS We conducted a population-based study using data between 2012 and 2016 from the national databases of Urban Employee Basic Medical Insurance and Urban Resident Basic Medical Insurance in China, covering about 480 million residents. Data from around 102.56 million participants aged 55 years and older during the study period were analyzed. A total of 190,560 incident hip fracture patients (mean age 77.05 years, standard deviation 8.94; 63.99% female) were identified. Primary outcomes included the age- and sex-specific incidences of hip fracture. Associated annual costs for hospitalization were also calculated. Incidence was described as per 100,000 person-years at risk, and 95% confidence intervals were computed assuming a Poisson distribution. Hip fracture incidence overall in China did not increase during the study period despite rapid population aging. Incidence per 100,000 was 180.72 (95% CI 137.16, 224.28; P < 0.001) in 2012 and 177.13 (95% CI 139.93, 214.33; P < 0.001) in 2016 for females, and 121.86 (95% CI 97.30, 146.42; P < 0.001) in 2012 and 99.15 (95% CI 81.31, 116.99; P < 0.001) in 2016 for males. For both sexes, declines in hip fracture incidence were observed in patients aged 65 years and older, although incidence was relatively stable in younger patients. However, the total absolute number of hip fractures in those 55 years and older increased about 4-fold. The total costs for hospitalization showed a steep rise from US$60 million to US$380 million over the study period. Costs for hospitalization per patient increased about 1.59-fold, from US$4,300 in 2012 to US$6,840 in 2016. The main limitation of the study was the unavailability of data on imaging information to adjudicate cases of hip fracture. CONCLUSIONS Our results show that hip fracture incidence among patients aged 55 and over in China reached a plateau between 2012 and 2016. However, the absolute number of hip fractures and associated medical costs for hospitalization increased rapidly because of population aging.

Abstract
UNLABELLED Osteoporosis is a metabolic disorder that results in increased bone fragility and risk of fractures. Hip fracture is the most important fragility fracture. Fracture Liaison Service (FLS) is a secondary prevention model which identifies patients at risk for fragility fractures. The introduction of an intensive FLS model could decrease 1-year-mortality of hip fracture patients. INTRODUCTION Hip fractures are a clinical manifestation of osteoporosis, and these patients are at risk of premature death and suffering subsequent fractures. FLS is an approach for secondary facture prevention by identifying patients with fragility fractures and initiating the appropriate treatment. Our objective is to analyze the effect of the FLS model over the first-year mortality rates following a hip fracture. METHODS We conducted a prospective cohort study on patients over 60 years of age who suffered a hip fracture during two consecutive years, before and after the implementation of the FLS in our center (i.e., between January 2016 and December 2017). Patients' information was withdrawn from our local computerized database. Patients were followed for 1 year after the hip fracture. Mortality and re-fracture rates were compared between the two groups using a multivariate Cox proportional hazard model. RESULTS A total of 724 individuals were included in this study (i.e., 357 before FLS implementation and 367 after FLS implementation). Anti-osteoporotic drugs were more frequently prescribed after FLS implementation [275 (74.9%) vs 44 (12.3%); p < 0.01]. A total of 74 (20.2%) patients after FLS implementation and 92 (25.8%) individuals before FLS implementation (p = 0.07) died during the follow-up period. A second fracture occurred in 17 (4.6%) patients after FLS implementation and 13 (3.6%) individuals before FLS implementation (p = 0.50). Patients who were treated with anti-osteoporotic drugs after the implementation of the FLS protocol had a lower 1-year mortality compared with patients managed before the implementation of the FLS protocol (treated or not treated with anti-osteoporotic drugs) [adjusted hazard ratio (HR) 0.66; 95% confidence interval (CI) 0.47-0.94; p < 0.05]. CONCLUSIONS We did not observe significant 1-year-mortality differences following a hip fracture between patients treated before the implementation of an FLS protocol and patients treated after its implementation. The application of the FLS did not affect the risk of suffering a second osteoporotic fracture. However, patients treated with anti-osteoporotic drugs in an FLS context had a lower mortality rate compared with patients managed before the implementation of the FLS. LEVEL OF CLINICAL EVIDENCE 2.

Abstract
BACKGROUND Available interventions for preventing fragility hip fractures show limited efficacy. Injection of a biomaterial as bone substitute could increase the fracture strength of the hip. This study aimed to show the feasibility of injecting a calcium sulfate/hydroxyapatite based biomaterial in the femoral neck and to calculate the consequent change in strength using the finite element method. METHODS Five patients were injected with 10 ml calcium sulfate/hydroxyapatite in their femoral neck. Quantitative CT scans were taken before and after injection. Five additional patients with fragility hip fractures were also scanned and the images from the non-fractured contralateral sides were used. Finite element models were created for all proximal femora with and without injection and the models were tested under stance and sideways fall loading until fracture. The change in fracture strength caused by the injection was calculated. Additionally, perturbations in volume, location, and stiffness of the injected material were created to investigate their contribution to the fracture strength increase. FINDINGS The 10 ml injection succeeded in all patients. Baseline simulations showed theoretical fracture strength increases of 0-9%. Volume increase, change in location and increase in stiffness of the material led to increases in fracture strength of 1-27%, -8-26% and 0-17%, respectively. Altering the location of the injection to a more lateral position and increasing the stiffness of the material led to increases in fracture strength of up to 42%. INTERPRETATION This study shows that an injection of calcium sulfate/hydroxyapatite is feasible and can theoretically increase the hip's fracture strength.

Abstract
OBJECTIVE We describe steps to operationalise a published conceptual framework for a contiguous hospitalisation episode using acute care hospital discharge abstracts. We then quantified the degree of bias induced by a first abstract episode, which does not account for hospital transfers. DESIGN Retrospective observational study. SETTING All acute care hospitals in nine Canadian provinces. PARTICIPANTS We retrieved acute hospitalisation discharge abstracts for 189 448 patients aged 65 years and older admitted to acute care with hip fracture between 2003 and 2013. PRIMARY AND SECONDARY OUTCOME MEASURES The percentage of patients treated surgically, delayed to surgery (defined as two or more days after admission) and dying, between contiguous hospitalisation episodes and the first abstract episodes of care. RESULTS Using contiguous hospitalisation episodes, 91.6% underwent surgery, 35.7% were delayed two or more days after admission and 6.7% died postoperatively, whereas, using the first abstract only, these percentages were 83.7%, 32.5% and 6.5%, respectively. CONCLUSION We demonstrate that not accounting for hospital transfers when evaluating the association between surgical timing and death underestimates reporting of the percentage of patients treated surgically and delayed to surgery by 9%, and the percentage who die after surgery by 3%. Researchers must be aware of this potential and avoidable bias as, depending on the purpose of the study, erroneous inferences may be drawn.

Abstract
BACKGROUND Osteoporosis and related fragility fractures are a global public health problem in which pharmaceutical agents targeting bone mineral density (BMD) are the first line of treatment. However, pharmaceuticals have no effect on improving other key fracture risk factors, including low muscle strength, power and functional capacity, all of which are associated with an increased risk for falls and fracture, independent of BMD. Targeted exercise training is the only strategy that can simultaneously improve multiple skeletal and fall-related risk factors, but it must be appropriately prescribed and tailored to the desired outcome(s) and the specified target group. OBJECTIVES In this review, we provide an overview of the general principles of training and specific loading characteristics underlying current exercise guidelines for the prevention of osteoporosis, and an update on the latest scientific evidence with regard to the type and dose of exercise shown to positively influence bone mass, structure and strength and reduce fracture risk in postmenopausal women.

Abstract
UNLABELLED There are care gaps in the evaluation and treatment of osteoporosis after a fragility fracture. The Joint Commission is considering adoption of core measures. We compared compliance between two secondary fracture prevention programs in our institution. Incorporating strengths of both may provide the best outcomes for secondary fracture prevention. PURPOSE There are significant care gaps in the evaluation and treatment of osteoporosis after occurrence of fragility fracture. The Joint Commission is considering adoption of a core measure set on osteoporosis-associated fractures, including laboratory assessment, bone density testing, and osteoporosis pharmacologic therapy. We compared compliance to these proposed measures between two secondary fracture prevention programs in patients hospitalized for acute fracture in an open medical system. METHODS We conducted a retrospective, single center medical records review of a nurse practitioner-led Fracture Liaison Service (FLS), a physician-led Fracture Prevention Program (FPP), and a historical time without any secondary fracture prevention program (Usual Care) for baseline care. Primary outcomes were the completion of five laboratory tests (calcium, 25-hydroxy vitamin D, renal function, liver function, and complete blood count), order placement and completion of dual x-ray absorptiometry (DXA) scan within 3 months, prescription of osteoporosis medication within 3 months, and medication adherence at 6 months after hospital discharge. RESULTS Completion of all five laboratory tests was higher in FPP versus FLS (84.7 vs. 36.9%, p < 0.001). DXA scan completion was higher in FPP than FLS but not statistically significant (66.7 vs. 54.9%, p = 0.11). Medication prescription at 3 months and adherence at 6 months were significantly higher in FPP versus FLS (65.3 vs. 24.0%, p < 0.001 and 70.8 vs. 27.7%, p < 0.001, respectively). CONCLUSION Incorporating strengths of both FLS (care coordination) and FPP (physician direction) may provide the best outcomes for secondary fracture prevention by ensuring laboratory and DXA testing and initiating osteoporosis medication.

Abstract
UNLABELLED Despite individual recommendations on osteoporosis management in patients after hip fracture surgery, addressed by orthopedic surgeons to Czech general practitioners, the patients remained undiagnosed and untreated because of provider-level barriers to post-fracture secondary prevention. PURPOSE The goal of the study was to assess whether an individual recommendation on osteoporosis treatment addressed to a hip fracture patient's GP would lead to better osteoporosis management. METHODS Two groups of patients who suffered hip fractures and were treated at the Orthopedic Department were evaluated. In 111 patients, general recommendations on osteoporosis treatment and fracture prevention were provided in a discharge report addressed to the GP. In the second group, 96 patients were provided individually with a detailed written set of recommendations on osteoporosis examination, treatment, and fracture prevention, which was also provided in the discharge report. A questionnaire to assess the provided care was mailed to the patients 5.3 ± 1.2 months of discharge. Those patients who did not return the questionnaires were contacted by phone. RESULTS The questionnaires were received from 44% and 49% of patients from the general and detailed recommendation groups, respectively. Along with the phone call, we were able to contact 78 (70.3%) and 68 (70.8%) patients from the general and detailed recommendation groups, respectively. GPs secured osteoporosis evaluation in 14.6% of the patients. Calcium supplementation and vitamin D supplementation were newly provided in 42.7 and 36.4% of the patients, respectively. Anti-resorptive therapy was newly provided in 8.3% of the patients. No significant differences between the groups were observed in osteoporosis evaluation, calcium and vitamin D supplementation, and anti-osteoporosis treatments. Out of 207 patients, further examination or treatment was requested by 45 patients (21.7%); 75 patients (36.2%) declared no interest in further care. CONCLUSION Recommendations on osteoporosis management addressed to Czech GPs after surgical fracture management had little effect on treatment. As the anti-osteoporotic preparations can only be prescribed by specialists, the availability of necessary examinations and treatment is limited by the motivation of GPs. Consequently, the implementation of Fracture Liaison Services to help close the care gap may be limited in the absence of participation by Czech GPs.

Abstract
BACKGROUND High incidence and increased mortality related to secondary, contralateral proximal femoral fractures may justify invasive prophylactic augmentation that reinforces the osteoporotic proximal femur to reduce fracture risk. Bone cement-based approaches (femoroplasty) may deliver the required strengthening effect; however, the significant variation in the results of previous studies calls for a systematic analysis and optimization of this method. Our hypothesis was that efficient generalized augmentation strategies can be identified via computational optimization. METHODS This study investigated, by means of finite element analysis, the effect of cement location and volume on the biomechanical properties of fifteen proximal femora in sideways fall. Novel cement cloud locations were developed using the principles of bone remodeling and compared to the "single central" location that was previously reported to be optimal. FINDINGS The new augmentation strategies provided significantly greater biomechanical benefits compared to the "single central" cement location. Augmenting with approximately 12ml of cement in the newly identified location achieved increases of 11% in stiffness, 64% in yield force, 156% in yield energy and 59% in maximum force, on average, compared to the non-augmented state. The weaker bones experienced a greater biomechanical benefit from augmentation than stronger bones. The effect of cement volume on the biomechanical properties was approximately linear. Results of the "single central" model showed good agreement with previous experimental studies. INTERPRETATION These findings indicate enhanced potential of cement-based prophylactic augmentation using the newly developed cementing strategy. Future studies should determine the required level of strengthening and confirm these numerical results experimentally.

Abstract
BACKGROUND Second hip fractures account for up to 15% of all hip fractures. We sought to determine if the proportion of hip fracture surgeries for second hip fracture changed over time in terms of patient and fracture characteristics. METHODS We reviewed the records of patients older than 60 years hospitalized for hip fracture surgery between 1990 and 2005 in British Columbia. We studied the proportion of surgeries for second hip fracture among all hip fracture surgeries. Linear regression tested for trends across fiscal years for women and men. RESULTS We obtained 46 341 patient records. Second hip fracture accounted for 8.3% of hip fracture surgeries. For women the proportion of second hip fracture surgeries increased linearly from 4% to 13% with each age decade (p = 0.001) and across fiscal years (p = 0.002). In men the proportion of second hip fracture surgeries was 5% for each age decade between the ages of 60 and 90 years across fiscal years, increasing to 8% for men older than 90 years across fiscal years (p = 0.20). These sex-specific trends were similar for both pertrochanteric and transcervical fracture types. CONCLUSION Second hip fracture surgeries account for an increasing proportion of hip fracture surgeries and may require more health care resources to minimize poorer reported outcomes. Future research should determine whether more health care resources are required to manage these patients and optimize their outcomes.

Abstract
Purpose. To understand older adults' engagement in their recovery experience and rehabilitation after a fall-related hip fracture. Method. 50 community-dwelling older adults recovering from a recent (3–12 months) hip fracture (32 women, 18 men) participated in telephone interviews using a semistructured format at 6 and 12 months after recruitment into the study. Interviews were conducted as part of a mixed-methods study designed to test the effect of a postoperative hip fracture management program (B4 Clinic). Results. Three substantive themes were identified in the qualitative data: (1) managing expectations; (2) engaging in physical activity; and (3) there is life after fracture. Participants shared valuable insight into how their expectations for their recovery period compared to their lived experience and the role of physical activity in their ability to return to their prefracture activities. Conclusions. Our findings reflect older adults' expectations for recovery from hip fracture. Encouraging engagement in rehabilitative exercises and addressing expectations prior to hospital discharge may improve patients' adherence to rehabilitation programs, functional outcomes, and postoperative quality of life. Implications for rehabilitation include the necessity for early and ongoing engagement of rehabilitation professionals.

Abstract
The high incidence of secondary hip fractures and the associated markedly increased mortality call for preventive actions that could help to avoid these injuries. By providing immediate strengthening and not relying on patient compliance, internal prophylactic augmentation of the osteoporotic proximal femur may overcome the main limitations of systemic bone drugs and wearable protective pads. However, such a method would have to provide sufficient and reliable strengthening effect with minimal risks and side effects to justify the need of an invasive treatment. The requirements for an internal reinforcement approach are thus strict and include mechanical, biological, clinical, ethical and financial criteria. Here we first attempt to describe the properties of an ideal augmentation method. Previously published methodologies and techniques developed at our research institute, including approaches using cements, metals, other materials or combined approaches, are then reviewed and evaluated according to these aspects. We conclude that none of the discussed methodologies appears to be able to deliver a sufficiently high gain-versus-risk ratio that could justify the clinical application and thus augmentation of the osteoporotic proximal femur remains a challenge. Finally, we provide suggestions for the development and evaluation of future strategies.

Abstract
UNLABELLED This review provides a critical analysis of currently available approaches to increase bone mass, structure and strength through drug therapy and of possible direct intra-osseous interventions for the management of patients at imminent risk of hip fracture. PURPOSE Osteoporotic hip fractures represent a particularly high burden in morbidity-, mortality- and health care-related costs. There are challenges and unmet needs in the early prevention of hip fractures, opening the perspective of new developments for the management of osteoporotic patients at imminent and/or at very high risk of hip fracture. Amongst them, preventive surgical intervention needs to be considered. METHODS A European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO)/International Osteoporosis Foundation (IOF) working group reviewed the presently available intervention modalities including preventive surgical options for hip fragility. This paper represents a summary of the discussions. RESULTS Prevention of hip fracture is currently based on regular physical activity; prevention of falls; correction of nutritional deficiencies, including vitamin D repletion; and pharmacological intervention. However, efficacy of these various measures to reduce hip fractures is at most 50% and may need months or years before becoming effective. To face the challenges of early prevention of hip fractures for osteoporotic patients at imminent and/or at very high risk of hip fracture, preventive surgical intervention needs further investigation. CONCLUSION Preventive surgical intervention needs to be appraised for osteoporotic patients at imminent and/or at very high risk of hip fracture.
