Abstract
Osteoporotic fractures, prevalent in the elderly, pose a significant health and economic burden. Current methods for predicting fracture risk, primarily relying on bone mineral density, provide only modest accuracy. If better spatial resolution of trabecular bone in a clinical scan were available, a more complete assessment of fracture risk would be obtained using microarchitectural measures of bone (i.e. trabecular thickness, trabecular spacing, bone volume fraction, etc.). However, increased resolution comes at the cost of increased radiation or can only be applied at small volumes of distal skeletal locations. This study explores super-resolution (SR) technology to enhance clinical CT scans of proximal femurs and better reveal the trabecular microarchitecture of bone. Using a deep-learning-based (i.e. subset of artificial intelligence) SR approach, low-resolution clinical CT images were upscaled to higher resolution and compared to corresponding MicroCT-derived images. SR-derived 2-dimensional microarchitectural measurements, such as degree of anisotropy, bone volume fraction, trabecular spacing, and trabecular thickness were within 16 % error compared to MicroCT data, whereas connectivity density exhibited larger error (as high as 1094 %). SR-derived 3-dimensional microarchitectural metrics exhibited errors <18 %. This work showcases the potential of SR technology to enhance clinical bone imaging and holds promise for improving fracture risk assessments and osteoporosis detection. Further research, including larger datasets and refined techniques, can advance SR's clinical utility, enabling comprehensive microstructural assessment across whole bones, thereby improving fracture risk predictions and patient-specific treatment strategies.

[PMID: 38898155 DOI: 10.1007/s11657-024-01409-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 06/05/2024] [Indexed: 06/21/2024]
Abstract
This study examined the clinical characteristics and refracture rates of Colombian patients with high- and very high-risk osteoporosis. This reveals osteoporosis diagnoses and treatment gaps. Only 5.3% of the patients were diagnosed with osteoporosis at discharge and 70.5% had refractures. This finding underscores the need for national policies to enhance osteoporosis prevention and treatment. PURPOSE This study aimed to assess the clinical features and refracture rates among patients with high- and very-high-risk osteoporosis in Colombia, highlighting diagnostic and treatment gaps. METHODS A retrospective observational study was conducted using the medical records of patients aged ≥ 50 years who experienced fragility fractures between 2003 and 2022. Clinical and demographic characteristics at the time of the initial fracture were analyzed, as well as the subsequent imminent risk (refracture rate) and the diagnosis and treatment gap. RESULTS 303.982 fragility fractures occurred, and only 5.3% of patients were diagnosed with osteoporosis upon discharge. The most prevalent index fractures were forearm, vertebral, rib, and hip. Only 17.8% of the cohort had a matched osteoporosis diagnosis, indicating a low healthcare capture. Among the diagnosed patients, 10.08% were classified as high- and very high-risk of fracture, predominantly women with a mean age of 73 years. Comorbidities included diabetes, Sjögren's syndrome, and heart failure. The prevalence of osteoporosis has increased significantly from 2004 to 2022, possibly due to improved detection methods, an aging population, or a combination of both. Despite this increase, treatment delay was evident. Refractures affected 70.5% of the patients, with forearm, hip, humerus, and vertebral fractures being the most common, with a mean time of refracture of 7 months. CONCLUSION Significant delays were observed in the diagnosis and treatment of fragility fractures. Colombia's government and health system must address osteoporosis by implementing national policies that prioritize osteoporosis and fragility fracture prevention and reduce delays in diagnosis and treatment.

Abstract
As there are effective treatments to reduce hip fractures, identification of patients at high risk of hip fracture is important to inform efficient intervention strategies. To obtain a new tool for hip fracture prediction, we developed a protein-based risk score in the Cardiovascular Health Study using an aptamer-based proteomic platform. The proteomic risk score predicted incident hip fractures and improved hip fracture discrimination in two Trøndelag Health Study validation cohorts using the same aptamer-based platform. When transferred to an antibody-based proteomic platform in a UK Biobank validation cohort, the proteomic risk score was strongly associated with hip fractures (hazard ratio per s.d. increase, 1.64; 95% confidence interval 1.53-1.77). The proteomic risk score, but not available polygenic risk scores for fractures or bone mineral density, improved the C-index beyond the fracture risk assessment tool (FRAX), which integrates information from clinical risk factors (C-index, FRAX 0.735 versus FRAX + proteomic risk score 0.776). The developed proteomic risk score constitutes a new tool for stratifying patients according to hip fracture risk; however, its improvement in hip fracture discrimination is modest and its clinical utility beyond FRAX with information on femoral neck bone mineral density remains to be determined.

Femoral neck width genetic risk score is a novel independent risk factor for hip fractures. J Bone Miner Res 2024; 39:241-251. [PMID: 38477772 PMCID: PMC11240160 DOI: 10.1093/jbmr/zjae002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 11/02/2023] [Accepted: 11/09/2023] [Indexed: 03/14/2024]
Abstract
Femoral neck width (FNW) derived from DXA scans may provide a useful adjunct to hip fracture prediction. Therefore, we investigated whether FNW is related to hip fracture risk independently of femoral neck bone mineral density (FN-BMD), using a genetic approach. FNW was derived from points automatically placed on the proximal femur using hip DXA scans from 38 150 individuals (mean age 63.8 yr, 48.0% males) in UK Biobank (UKB). Genome-wide association study (GWAS) identified 71 independent genome-wide significant FNW SNPs, comprising genes involved in cartilage differentiation, hedgehog, skeletal development, in contrast to SNPs identified by FN-BMD GWAS which primarily comprised runx1/Wnt signaling genes (MAGMA gene set analyses). FNW and FN-BMD SNPs were used to generate genetic instruments for multivariable Mendelian randomization. Greater genetically determined FNW increased risk of all hip fractures (odds ratio [OR] 1.53; 95% CI, 1.29-1.82 per SD increase) and femoral neck fractures (OR 1.58;1.30-1.92), but not trochanteric or forearm fractures. In contrast, greater genetically determined FN-BMD decreased fracture risk at all 4 sites. FNW and FN-BMD SNPs were also used to generate genetic risk scores (GRSs), which were examined in relation to incident hip fracture in UKB (excluding the FNW GWAS population; n = 338 742, 3222 cases) using a Cox proportional hazards model. FNW GRS was associated with increased risk of all incident hip fractures (HR 1.08;1.05-1.12) and femoral neck fractures (hazard ratio [HR] 1.10;1.06-1.15), but not trochanteric fractures, whereas FN-BMD GRS was associated with reduced risk of all hip fracture types. We conclude that the underlying biology regulating FNW and FN-BMD differs, and that DXA-derived FNW is causally related to hip fractures independently of FN-BMD, adding information beyond FN-BMD for hip fracture prediction. Hence, FNW derived from DXA analyses or a FNW GRS may contribute clinically useful information beyond FN-BMD for hip fracture prediction.

Abstract
Hip fractures are associated with significant disability, high cost, and mortality. However, the exact biological mechanisms underlying susceptibility to hip fractures remain incompletely understood. In an exploratory search of the underlying biology as reflected through the circulating proteome, we performed a comprehensive Circulating Proteome Association Study (CPAS) meta-analysis for incident hip fractures. Analyses included 6430 subjects from two prospective cohort studies (Cardiovascular Health Study and Trøndelag Health Study) with circulating proteomics data (aptamer-based 5 K SomaScan version 4.0 assay; 4979 aptamers). Associations between circulating protein levels and incident hip fractures were estimated for each cohort using age and sex-adjusted Cox regression models. Participants experienced 643 incident hip fractures. Compared with the individual studies, inverse-variance weighted meta-analyses yielded more statistically significant associations, identifying 23 aptamers associated with incident hip fractures (conservative Bonferroni correction 0.05/4979, P < 1.0 × 10-5). The aptamers most strongly associated with hip fracture risk corresponded to two proteins of the growth hormone/insulin growth factor system (GHR and IGFBP2), as well as GDF15 and EGFR. High levels of several inflammation-related proteins (CD14, CXCL12, MMP12, ITIH3) were also associated with increased hip fracture risk. Ingenuity pathway analysis identified reduced LXR/RXR activation and increased acute phase response signaling to be overrepresented among those proteins associated with increased hip fracture risk. These analyses identified several circulating proteins and pathways consistently associated with incident hip fractures. These findings underscore the usefulness of the meta-analytic approach for comprehensive CPAS in a similar manner as has previously been observed for large-scale human genetic studies. Future studies should investigate the underlying biology of these potential novel drug targets.

Abstract
Background A few observational studies revealed that amyotrophic lateral sclerosis (ALS) was tightly connected with osteoporosis. However, the results of previous studies were inconsistent, and the causal effect of ALS on osteoporosis has not been investigated. To do so, the two-sample Mendelian randomization (MR) method was employed to estimate the causality. Methods The instrumental variables (IVs) for ALS were selected from one GWAS summary dataset (27,205 ALS cases and 110,881 controls), and bone mineral density (BMD) in the femoral neck (FN), lumbar spine (LS), and forearm, extracted from another large-scale GWAS summary database (53,236 cases), were used as phenotypes for osteoporosis. Random-effects inverse variance weighted (IVW), MR Egger, weighted median, simple mode, and weighted mode were conducted to evaluate the causality. Sensitivity analyses were further performed to explore heterogeneity and pleiotropy. Results A total of 10 qualified SNPs were finally selected as proxies for ALS. The results of random effects from IVW revealed that ALS has no causal effect on FN-BMD (beta: -0.038, 95% CI: -0.090 to 0.015, SE: 0.027, p = 0.158), LS-BMD (beta: -0.015, 95% CI: -0.076 to 0.046, SE: 0.031, p = 0.629), and forearm BMD (beta: 0.044, 95% CI: -0.063 to 0.152, SE: 0.055, p = 0.418). These results were confirmed using the MR-Egger, weighted median, simple model, and weighted model. No heterogeneity or pleiotropy was detected (p > 0.05 for all). Conclusion Contrary to previous observational studies, our study figured out that no causal effect existed between ALS and osteoporosis. The disparity in results is probably attributed to secondary effects such as physical inactivity and muscle atrophy caused by ALS.

Abstract
This joint report from the Italian Society of Orthopaedics and Traumatology (SIOT) and the Italian Society of Periodontology and Implantology (SIdP) aims for a consensus around the scientific rationale and clinical strategy for the management of osteoporotic patients affected by periodontitis who are undergoing anti-resorptive (AR) therapy to manage the risk of the occurrence of a medication-related osteonecrosis of the jaws (MRONJ). Osteoporosis and periodontitis are chronic diseases with a high prevalence in aging patients, and they share some of the same pathogenetic mechanisms based upon inflammation. Available evidence shows the relationship among osteoporosis, AR agents, periodontitis and implant therapy in relation to the incidence of MRONJ. Uncontrolled periodontitis may lead to tooth loss and to the need to replace teeth with dental implants. Tooth extraction and surgical dental procedures are recognized as the main risk factors for developing MRONJ in individuals taking AR therapy for osteometabolic conditions. Although the incidence of MRONJ in osteometabolic patients taking AR therapy may be as low as 0.9%, the increasing prevalence of osteoporosis and the high prevalence of periodontitis suggest that this potential complication should not be overlooked. Good clinical practice (GCP) guidelines are proposed that aim at a more integrated approach (prescriber, dentist, periodontist and dental hygienist) in the management of periodontitis patients undergoing AR therapy for osteometabolic disorders to reduce the risk of MRONJ. Dental professional and prescribers should educate patients regarding the potential risk associated with the long-term use of AR therapy and oral health behavior.

Current approaches to secondary prevention after hip fracture in England and Wales - an analysis of trends between 2016 and 2020 using the National Hip Fracture Database (NHFD). Arch Osteoporos 2023; 18:93. [PMID: 37428295 PMCID: PMC10333382 DOI: 10.1007/s11657-023-01282-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 05/11/2023] [Indexed: 07/11/2023]
Abstract
Hip fractures are strong risk factors for further fractures. However, using the National Hip Fracture Database, we observed that in England and Wales, 64% of patients admitted on oral bisphosphonates were discharged on the same and injectable drug use varies from 0-67% and 0.2%-83.6% were deemed "inappropriate" for bone protection. This variability requires further investigation. INTRODUCTION A key aim for the National Hip Fracture Database (NHFD) is to encourage secondary fracture prevention of the 75,000 patients who break their hip annually in the UK, through bone health assessment and appropriate provision of anti-osteoporosis medication (AOM). We set out to describe trends in anti-osteoporosis medication prescription and examine the types of oral and injectable AOMs being prescribed both before and after a hip fracture. METHODS We used data freely available from the NHFD www.nhfd.co.uk to analyse trends in oral and injectable AOM prescription across a quarter of a million patients presenting between 2016 and 2020, and more detailed information on the individual type of AOM prescribed for 63,705 patients from 171 hospitals in England and Wales who presented in 2020. RESULTS Most patients (88.3%) are not taking any AOM when they present with a hip fracture. Half of all patients (50.8%) were prescribed AOM treatment by the time of discharge, but the proportion deemed 'inappropriate for AOM' varied hugely (0.2-83.6%) in different hospitals. Nearly two-thirds (64.2%) of those previously taking an oral bisphosphonate were simply discharged on the same type of medication. The total number of patients discharged on oral medication fell by over a quarter in these five years. The number discharged on injectables increased by nearly three-quarters to 14.2% over the same period, but remains hugely variable across the country, with rates ranging from 0-67% across different units. CONCLUSION A recent hip fracture is a strong risk factor for future fractures. The huge variability in approaches, and in particular the use of injectables, in different trauma units across England and Wales requires further investigation.

Abstract
Osteoporotic fractures are one of the major problems facing healthcare systems worldwide. Undoubtedly, fragility fractures of the hip represent a far greater burden in terms of morbidity, mortality, and healthcare costs than other fracture sites. However, despite the significant impact on the health and quality of life of older adults, there is a general lack of awareness of osteoporosis, which results in suboptimal care. In fact, most high-risk individuals are never identified and do not receive adequate treatment, leading to further fragility fractures and worsening health status. Furthermore, considering the substantial treatment gap and the proven cost-effectiveness of fracture prevention programs such as Fracture Liaison Services, urgent action is needed to ensure that all individuals at high risk of fragility fracture are adequately assessed and treated. Based on this evidence, the aim of our review was to (i) provide an overview and comparison of the burden and management of fragility fractures, highlighting the main gaps, and (ii) highlight the importance of using alternative approaches, both surgical and non-surgical, with the aim of implementing early prevention of osteoporotic fractures and improving the management of osteoporotic patients at imminent and/or very high risk of fracture.

Abstract
Hip fracture is the clinically most important fracture, but the genetic architecture of hip fracture is unclear. Here, we perform a large-scale hip fracture genome-wide association study meta-analysis and Mendelian randomization study using five cohorts from European biobanks. The results show that five genetic signals associate with hip fractures. Among these, one signal associates with falls, but not with bone mineral density (BMD), while four signals are in loci known to be involved in bone biology. Mendelian randomization analyses demonstrate a strong causal effect of decreased femoral neck BMD and moderate causal effects of Alzheimer's disease and having ever smoked regularly on risk of hip fractures. The substantial causal effect of decreased femoral neck BMD on hip fractures in both young and old subjects and in both men and women supports the use of change in femoral neck BMD as a surrogate outcome for hip fractures in clinical trials.

Abstract
This study evaluated the effects of AGN1, a triphasic calcium-based material, and alendronate (A) on distal femoral defect bone repair in ovariectomized (OVX) rats. Of 106 rats, 92 were OVX'ed at 12 weeks old and underwent a 12-week induction period. Animals were randomized into five groups: OVX Control, OVX Alendronate Control, Normal Control, OVX Implantation, OVX Alendronate + Implantation. OVX Alendronate Control and OVX Alendronate + Implantation groups received alendronate injection twice weekly (0.015 mg/kg) from 6 weeks until sacrifice. Twelve weeks after OVX, 2.5 mm diameter by 4.0 mm long cylindrical, bilateral distal femoral defects were created in experimental animals. One defect was left empty, and one filled with AGN1. Dual-energy X-ray absorptiometry, microcomputed tomography, and histomorphometry were performed 0-, 6-, 12-, and 18-week postdefect/implantation surgery (N = 6-8/group). Results showed OVX induced significant and progressive bone loss which alendronate prevented. Histomorphometry demonstrated rapid AGN1 resorption: AGN1 resorbed from 95.1 ± 0.7% filling of the implant site (week 0) to 1.3 ± 1.0% (18 weeks) with no significant alendronate effect (1.6 ± 1.1%, 18 weeks). Bone formation in empty defects consisted primarily of cortical wall healing, whereas AGN1 implants demonstrated cortical wall healing with new trabecular bone filling the subcortical space. Alendronate dramatically increased bone formation in empty and AGN1 defects. We conclude AGN1 is resorbed and replaced by new cortical and trabecular bone in this OVX model, and alendronate did not compromise these effects.

Abstract
A non-comparative multi-centre and international pilot study have been carried on Y-STRUT® (Hyprevention, France), an implantable medical device meant to reinforce the hip to reduce the risk of a contralateral hip fracture. Objectives of the study were to determine the feasibility and tolerance of the procedure. Methods Patients older than 60 years were recruited when presenting at the emergency departments with a low-energy pertrochanteric fracture on one side and with a fracture risk assessed for the contralateral side with BMD, T-Score or other bone quality evaluation tool, FRAX index, or fall risk assessment. Pain and functional ability were assessed at the different follow-up visits using VAS, WOMAC and OHS-12 scores. Results Twelve patients were included and reached a one-year follow-up. Mean age was 82 years old (65 - 91). The average hospital stay was 13 days (3 - 29). The prophylactic surgery did not delay the hospital discharge for any patient. The procedure did not lead to unresolvable serious adverse events. At 3 weeks, all patients were able to walk 6 meters, half of them in less of 30 seconds. Minimal pain was reported all along the follow-up visits, except at 3 years when one patient presented high pain in both hips. WOMAC and OHS-12 scores showed a moderate to mild hip impairment. Conclusion The good short and medium-term outcomes of this pilot study demonstrate the feasibility and the tolerability of the device. Further studies should focus on the efficacy of this immediate and lasting bone reinforcement technique.

Abstract
BACKGROUND Proximal femoral fractures (PFFs) are a public health issue due to their high frequency. The frequency of a second PFF on the other side is estimated at 10%. This estimation is controversial, however, and the risk factors have not been evaluated in a large population of French patients. The objective of this retrospective case-control study was to determine: (1) the incidence of second PFFs and (2) their risk factors. HYPOTHESIS The incidence of second PFFs is >2% after 1 year and >5% after 3 years. MATERIAL AND METHODS We conducted a case-control study in a population of consecutive patients managed surgically for PPF at the Lyon Sud Hospital between 2013 and 2014. We analysed the following clinical factors: age, sex, body mass index (BMI), institutionalisation, the Parker score, the American Society of Anesthesiologists score (ASA), comorbidities, and the use of psychoactive drugs. RESULTS We included 474 PFFs (trochanter, n=240 and neck, n=234) of which 36 were bilateral. The contralateral fracture occurred within 1 year of the first fracture in 6/474 (1.3%) cases and within 3 years in all 36 cases (7.6%). The case-control study comprised 49 cases with bilateral PFF and 161 controls with no second hip fracture within 3 years. Risk factors for a second hip fracture were age older than 90 years (odds ratio [OR]=5.44; 95% confidence interval [95%CI], 112-2642 (p=0.002)) and a history of heart disease (OR, 2.18; 95%CI, 1.06-4.47 [p=0.03]). A Parker score≥6 was protective (OR, 0.84; 95%CI, 0.71-0.99 [p=0.03]). Mortality after 3 years was 42% (201/474), and 13% (63/474) of patients were lost to follow-up. DISCUSSION Age older than 90 years, a Parker score below 6, and a history of heart disease are risk factors for a second PFF within 3 years after the first PFF.

Abstract
BACKGROUND AND AIMS The most recent guidelines suggest treating patients whose FRAX 10-year fracture risk scores are ≥ 20%. However, this method of evaluation does not take into account parameters that are nonetheless relevant to the therapeutic choice. Our aim was to compare the therapeutic choices for treatment based on a wider assessment (real-world practice) with those based on FRAX scores, taking 20% as the cut-off score. METHODS We obtained the medical history, bone mineral density (BMD) values, and the presence of major fragility fractures in a sample of 856 postmenopausal women. The 10-year FRAX risk of major osteoporotic fracture was calculated, and patients were grouped into risk classes ("FRAX < 20%" = low, "FRAX ≥ 20%" = high); we then compared the treated and untreated patients in each class. After an average interval of 2.5 years, changes in lumbar and femoral BMD and appearances of new fragility fractures were recorded. RESULTS 83% of high-risk patients and 57% of low-risk patients were treated. The therapeutic decision was based mainly on densitometric values and the presence of vertebral fractures. At the 2.5 year follow-up, lumbar spine and femur BMD had decreased in the untreated group; 9.9% of the treated patients developed new vertebral fragility fractures, compared with 5.3% of the untreated patients. DISCUSSION AND CONCLUSIONS Our wider assessment designated as at high fracture risk a group of patients who had not been identified by the FRAX assessment. FRAX could underestimate the risk of fracture in older people, for which the therapeutic choice should consider a broader approach, also based on individual patient's needs.

[PMID: 34744020 DOI: 10.1016/j.bone.2021.116246] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 10/22/2021] [Accepted: 10/25/2021] [Indexed: 11/02/2022]
Abstract
BACKGROUND Fractures secondary to osteoporosis, particularly those of the hip and spine, are a major public health concern with high social and economic costs. The Local Osteo-Enhancement Procedure (LOEP) is an approach intended to strengthen skeletal areas that are at the highest risk for fracture due to osteoporosis. LOEP involves the implantation of AGN1, a triphasic, calcium-based, osteoconductive material which is then resorbed and replaced by bone. Since alendronate is the most prescribed osteoporotic treatment, the purpose of this canine study is to determine if the newly formed bone has the same properties as normal bone and whether alendronate treatment impacts AGN1 resorption and replacement with bone. METHODS Sixty skeletally mature male hounds (24-38 kg) were evenly divided between alendronate (0.2 mg/kg/day) and non-alendronate treatment groups. A critical-size core bone defect created in one proximal humerus was implanted with AGN1 while the contralateral non-operated humerus served as a paired control in each animal. Animals were sacrificed 13, 26, and 52 weeks post-operatively (10 per treatment per timepoint). The control and treatment site bone specimens from each animal were examined using radiographic, histomorphometric, and biomechanical techniques. Results between alendronate-treated and non-alendronate-treated animals were compared as groups. RESULTS AGN1 implant material was consistently resorbed and replaced by bone in all animals. At 52 weeks, only minimal residual implant material could be detected (0.9 ± 2.3% non-alendronate group; 2.2 ± 3.1% alendronate group), and new bone filled the defects in both the non-alendronate and alendronate groups. At 13 and 26 weeks, microCT revealed the newly formed bone in the defects had significantly higher trabecular bone volume and number connectivity than control bone in both groups. Mechanical testing demonstrated that the new bone had ultimate compressive strength and modulus equivalent to control bone as early as 13 weeks post-surgery which was maintained to 52 weeks in both groups. CONCLUSIONS In this canine critical-sized humeral core defect model, AGN1 was progressively replaced by normal bone as evaluated by all outcome measures. Concurrent alendronate therapy did not significantly impact AGN1 resorption or new bone formation. These results demonstrate that AGN1 can be used in conjunction with alendronate in non-osteoporotic animals. CLINICAL RELEVANCE This study suggests that the AGN1 implant material demonstrates potential for local restoration of bone in critical-size core defects, and that the material is compatible with alendronate drug therapy. Further studies will be required to determine if these results apply to other osteoporosis medications.

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. [PMID: 34861519 DOI: 10.1016/j.jmbbm.2021.104957] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 11/02/2021] [Accepted: 11/07/2021] [Indexed: 12/26/2022]
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
OBJECTIVE To review evidence regarding osteoporosis screening, prevention, diagnosis, and management in the past decade and update the position statement published by The North American Menopause Society (NAMS) in 2010 regarding the management of osteoporosis in postmenopausal women as new therapies and paradigms have become available. DESIGN NAMS enlisted a panel of clinician experts in the field of metabolic bone diseases and/or women's health to review and update the 2010 NAMS position statement and recommendations on the basis of new evidence and clinical judgement. The panel's recommendations were reviewed and approved by the NAMS Board of Trustees. RESULTS Osteoporosis, especially prevalent in older postmenopausal women, increases the risk of fractures that can be associated with significant morbidity and mortality. Postmenopausal bone loss, related to estrogen deficiency, is the primary contributor to osteoporosis. Other important risk factors for postmenopausal osteoporosis include advanced age, genetics, smoking, thinness, and many diseases and drugs that impair bone health. An evaluation of these risk factors to identify candidates for osteoporosis screening and recommending nonpharmacologic measures such as good nutrition (especially adequate intake of protein, calcium, and vitamin D), regular physical activity, and avoiding smoking and excessive alcohol consumption are appropriate for all postmenopausal women. For women at high risk for osteoporosis, especially perimenopausal women with low bone density and other risk factors, estrogen or other therapies are available to prevent bone loss. For women with osteoporosis and/or other risk factors for fracture, including advanced age and previous fractures, the primary goal of therapy is to prevent new fractures. This is accomplished by combining nonpharmacologic measures, drugs to increase bone density and to improve bone strength, and strategies to reduce fall risk. If pharmacologic therapy is indicated, government-approved options include estrogen agonists/antagonists, bisphosphonates, RANK ligand inhibitors, parathyroid hormone-receptor agonists, and inhibitors of sclerostin. CONCLUSIONS Osteoporosis is a common disorder in postmenopausal women. Management of skeletal health in postmenopausal women involves assessing risk factors for fracture, reducing modifiable risk factors through dietary and lifestyle changes, and the use of pharmacologic therapy for patients at significant risk of osteoporosis or fracture. For women with osteoporosis, lifelong management is necessary. Treatment decisions occur continuously over the lifespan of a postmenopausal woman. Decisions must be individualized and should include the patient in the process of shared decision-making.

Abstract
Delirium is a common postoperative complication of patients with hip fracture, yet the risk factors for postoperative delirium in patients with hip fracture remain unclear. We aimed to evaluate the associated risk factors of postoperative delirium in patients with hip fracture, to provide evidence for formulating coping measures of postoperative delirium prevention and treatment in clinical practice.Patients undergoing surgery for hip fracture from March 1, 2018 to September 30, 2020 in our hospital were included. The related characteristics and related lab examination results were reviewed and collected. The univariate and logistic regression analyses were performed to identify the potential risk factors.A total of 462 patients were included, the incidence of postoperative delirium in patients with hip fracture was 16.02%. Logistic regression analyses indicated that history of delirium (OR = 4.38, 1.15-9.53), diabetes mellitus (OR = 5.31, 1.23-10.75), hypoalbuminemia (OR = 4.97, 1.37-9.86), postoperative hypoxemia (OR = 5.67, 2.24-13.42), and body mass index (BMI) (kg/m2) (OR = 3.03, 1.36-6.18) were the independent risk factors for the delirium in patients with hip fracture surgery (all P < 0.05). The cutoff value of postoperative blood sugar, albumin, and BMI for delirium prediction was 8.05 (mmol/L), 32.26 (g/L), and 19.35 (kg/m2), respectively, and the area under curve of postoperative blood sugar, albumin, and BMI was 0.792, 0.714, and 0.703, respectively.Those patients with a history of delirium, postoperative hypoxemia, blood glucose ≥8.05 mmol/L, albumin ≤32.26 g/L, and BMI ≤19.35 kg/m2 particularly need the attention of healthcare providers for the prevention of delirium.

Abstract
INTRODUCTION Fragility hip fractures are common and costly. Secondary fracture prevention is a treatment goal following hip fracture; however, the number of those that proceed to fracture their contralateral hip in Ireland is unknown. There are plans to introduce a Fracture Liaison Service Database in Ireland which will aim to prevent secondary fractures. To establish a baseline figure for secondary hip fractures, the injury radiographs of 1284 patients from 6 teaching hospitals over a 1-year period were reviewed. METHODS Irish Hip Fracture Datasheets and corresponding injury radiographs were reviewed locally for all hip fractures within each respective teaching hospital for a 1-year period (2019). RESULTS A total of 8.7% of all fragility hip fractures across the 6 hospitals were secondary hip fractures (range 4.9-11.5%). 46% occurred within years 1 to 3 following index hip fracture. Forty-eight per cent of patients were started on bone protection medications following their second hip fracture. DISCUSSION/CONCLUSION Approximately 1 in 11 hip fractures treated across the 6 teaching hospitals assessed in 2019 was a patient's second hip fracture. We advocate for the widespread availability of Fracture Liaison Services to patients throughout Ireland to assist secondary fracture prevention.

Abstract
Background and objectives: Hip fracture is a major public health issue. Those fractures lead to high costs and a decrease in quality of life. A national French survey was conducted, with the objectives to firstly assess the current management of hip fracture and its prevention, both in the osteoporotic and cancer settings, and secondly to evaluate the opinions of physicians on the potential use of minimally invasive implantable devices to prevent hip fracture in alternative of surgery. Materials and methods: This national survey was conducted in France between April and July 2017. Questionnaires were sent to orthopedic surgeons, interventional radiologists, oncologists, and rheumatologists. Completed questionnaires were analyzed and compared according to two indications: orthopedics-traumatology and oncology. Factors associated with these responses were assessed using univariable analyses, based on chi-square tests or an exact Fisher test, as appropriate. Results: A total of 182 questionnaires were completed and further analyzed. Physicians have highlighted the need for a low re-fracture rate and to improve life expectancy for more than 1 year (50% for responders of the orthopedics-traumatology questionnaire and 80% for the responders interested in both indications), as well as quality of life (12.5% and 31%, respectively), but with no significant differences in the oncologic indication. Most of the experts were willing to use or prescribe implantable devices for prevention (63% in orthopedics-traumatology and 93% in oncology), although limited clinical experience (54 and 58%) and surgical risk (around 30% in each indication) were considered as limits. Conclusions: Prevention of hip fracture remains a concern for physicians. More clinical experience with implantable devices, in particular in cancer patients, is needed, but implemented in a strategy to maximize patient recovery while reducing costs.

Abstract
Introduction: The purpose of our study is to compare between physical activity (PA) in postmenopausal women with osteoporotic vertebral fractures and healthy women and to evaluate the relationship between PA and clinical and paraclinical parameters related to osteoporotic fracture.
Methods: A case-control cross- sectional study, which included 128 postmenopausal women with densitometric osteoporosis as defined by Worlds Health Organization, with at least one radiological vertebral fracture. Physical activity was assessed by the International Physical Activity Questionnaire (IPAQ) short version with three items: vigorous, moderate activity and walking. Bone mineral density (BMD) and X-rays were performed in all patients. The controls were healthy women included in a randomized order in the general population, they were matched for age.
Results: 128 patients with a mean age of 61.01± 8.40 years were included. 100 controls were included with a mean age of 60.61 ± 8.25 years. The patients had a median age of menopausal of 48.90 years [48-50], were osteoporotic in 49.2% and had osteopenia in 34.9%. 84 patients had a current back pain, and an average of three vertebral fracture with a median Genant score of 3.02[1-23]. There was no significant difference between the subjects of our study for total PA. However, vigorous-intensity activity and walking were significantly different between the two groups (p<0.05). Three independent factors were associated with a reduction of total physical activity: age, Genant score and physical function (for all p<0.05). In multivariate analysis, a significant association between total physical activity and age (p=0.003), trochanter BMD (p=0.01), Genant score (p=0.02) and physical function (2nd domain QUALEFFO) (p=0.01) persisted.
Conclusion: In Moroccan postmenopausal women with osteoporotic vertebral fractures, PA is decreased with the severity of vertebral fractures and with the increasing age.

Abstract
UNLABELLED This first-in-human study of AGN1 LOEP demonstrated that this minimally-invasive treatment durably increased aBMD in femurs of osteoporotic postmenopausal women. AGN1 resorption was coupled with new bone formation by 12 weeks and that new bone was maintained for at least 5-7 years resulting in substantially increased FEA-estimated femoral strength. INTRODUCTION This first-in-human study evaluated feasibility, safety, and in vivo response to treating proximal femurs of postmenopausal osteoporotic women with a minimally-invasive local osteo-enhancement procedure (LOEP) to inject a resorbable triphasic osteoconductive implant material (AGN1). METHODS This prospective cohort study enrolled 12 postmenopausal osteoporotic (femoral neck T-score ≤ - 2.5) women aged 56 to 89 years. AGN1 LOEP was performed on left femurs; right femurs were untreated controls. Subjects were followed-up for 5-7 years. Outcomes included adverse events, proximal femur areal bone mineral density (aBMD), AGN1 resorption, and replacement with bone by X-ray and CT, and finite element analysis (FEA) estimated hip strength. RESULTS Baseline treated and control femoral neck aBMD was equivalent. Treated femoral neck aBMD increased by 68 ± 22%, 59 ± 24%, and 58 ± 27% over control at 12 and 24 weeks and 5-7 years, respectively (p < 0.001, all time points). Using conservative assumptions, FEA-estimated femoral strength increased by 41%, 37%, and 22% at 12 and 24 weeks and 5-7 years, respectively (p < 0.01, all time points). Qualitative analysis of X-ray and CT scans demonstrated that AGN1 resorption and replacement with bone was nearly complete by 24 weeks. By 5-7 years, AGN1 appeared to be fully resorbed and replaced with bone integrated with surrounding trabecular and cortical bone. No procedure- or device-related serious adverse events (SAEs) occurred. CONCLUSIONS Treating femurs of postmenopausal osteoporotic women with AGN1 LOEP results in a rapid, durable increase in aBMD and femoral strength. These results support the use and further clinical study of this approach in osteoporotic patients at high risk of hip fracture.

Abstract
OBJECTIVES This study aims to test the feasibility of the Fracture and Mortality Risk Evaluation (FAME) Index. PATIENTS AND METHODS Two academic centers in Lithuania and Turkey participated in this retrospective study conducted between November 2018 and July 2019. A total of 100 consecutive patients (22 males, 78 females; mean age 78.9 years; range, 45 to 100 years) with low energy proximal femur fractures admitted for surgery were included in the study. Fracture Risk Assessment tool (FRAX) and the Sernbo scores were calculated and patients were classified into one of the nine subcategories of the FAME Index. RESULTS Demographics and FAME Index classifications were similar between centers. Patients with high risk of fracture and low risk of mortality accounted for 18% of all patients, which is the FAME Index subcategory to theoretically benefit from cancellous bone augmentation during internal fixation of a fragility hip fracture the most. CONCLUSION The FAME Index was successfully applied in clinical emergency setting utilizing a simple form, and demonstrated promising potential in stratification of hip fractures most suitable for screw and device augmentation. Larger studies with at least one-year of follow-up are warranted to verify the validity of FAME Index.

CTXA hip: the effect of partial volume correction on volumetric bone mineral density data for cortical and trabecular bone. Arch Osteoporos 2020; 15:50. [PMID: 32193671 DOI: 10.1007/s11657-020-00721-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 02/25/2020] [Indexed: 02/03/2023]
Abstract
UNLABELLED This study compares the results of computed tomography X-ray absorptiometry (CTXA) hip volumetric BMD (vBMD) analyses of cortical and trabecular bone with and without partial volume correction. For cortical bone in some circumstances, corrected cortical volumes were negative and corrected vBMD was very high. For trabecular bone, the correction effects are smaller. CTXA volumetric data should be interpreted with caution. PURPOSE Previous studies have reported concerns about the reliability of CTXA hip cortical vBMD measurements generated using partial volume (PV) correction (the "default" analysis, with cortical PV correction). To date, no studies have examined the results of the alternative ("new") analysis (with trabecular PV correction). This study presents in vivo and phantom data comparing the corrected and uncorrected data for cortical and trabecular bone respectively. METHODS We used the commercial QCTPro CTXA software to analyze CT scans of 129 elderly Chinese men and women and an anthropomorphic European Proximal Femur phantom (EPFP) and accessed data for two alternative scan analyses using the database dump utility. The CTXA software gives the user two methods of performing the PV correction: (1) a default analysis in which only cortical bone results are corrected; (2) a new analysis in which only trabecular bone results are corrected. Both methods are based on a numerical recalculation of vBMD values without any change in volume of interest (VOI) placement. RESULT In vivo, the results of the two analyses for integral bone were the same while cortical and trabecular results were different. PV correction of cortical bone led to a decrease of cortical volume for all four VOIs: total hip (TH), femoral neck (FN), trochanter (TR), and intertrochanter (IT) volumes were reduced on average by 7.8 cm3, 0.9 cm3, 2.5 cm3, and 4.3 cm3 respectively. For TR, where cortex was thinnest, average corrected cortical volume was negative (- 0.4± 1.3 cm3). Corrected cortical vBMD values were much larger than uncorrected ones for TH, FN, and IT. Scatter plots of corrected cortical vBMD against cortical bone thickness showed that elevated results correlated with thinner cortices. When trabecular bone was corrected for the PV effect, trabecular volumes of TH, FN, TR, and IT were reduced on average by 7.9 cm3, 0.8 cm3, 2.6 cm3, and 4.4 cm3 respectively, while vBMD measurements were increased correspondingly. The trabecular volume and vBMD measurements of the two datasets both had highly positive correlations. For the EPFP, the PV-corrected FN data deviated from the nominal phantom value, but was closer for the TR and IT VOIs. Both corrected and uncorrected data overestimated trabecular vBMD, with the corrected results showing greater deviation from nominal values. CONCLUSION The default and new CTXA analyses for volumetric data generate different results, both for cortical and trabecular bone. For cortical bone, the uncorrected results are subject to partial volume effects but the correction method of the default analysis overcorrects the effect leading to in part unreasonable results for cortical bone volume and BMD. For trabecular bone, the correction effects are smaller. CTXA volumetric data should be interpreted with caution.

Abstract
In view of the high imminent risk for subsequent fractures, evaluation as early as possible after the fracture will result in early decisions about drug treatment, fall prevention and nutritional supplements. Drug treatment includes anti-resorptive and bone forming agents. Anti-resorptive therapy with broad spectrum fracture prevention and early anti-fracture effects are the first choice. In patients with multiple or severe VFs, the bone forming agent teriparatide should be considered. Adequate calcium and vitamin D are needed in all patients, together with appropriate nutrition, including adequate protein intake.

Abstract
Current pharmaceutical therapies can reduce hip fractures by up to 50%, but compliance to treatment is low and therapies take up to 18 months to reduce risk. Thus, alternative or complementary approaches to reduce the risk of hip fracture are needed. The AGN1 local osteo-enhancement procedure (LOEP) is one such alternative approach, as it is designed to locally replace bone lost due to osteoporosis and provide immediate biomechanical benefit. This in vitro study evaluated the initial biomechanical impact of this treatment on human cadaveric femurs. We obtained 45 pairs of cadaveric femurs from women aged 77.8 ± 8.8 years. One femur of each pair was treated, while the contralateral femur served as an untreated control. Treatment included debridement, irrigation/suction, and injection of a triphasic calcium-based implant (AGN1). Mechanical testing of the femora was performed in a sideways fall configuration 24 h after treatment. Of the 45 pairs, 4 had normal, 16 osteopenic, and 25 osteoporotic BMD T-scores. Altogether, treatment increased failure load on average by 20.5% (p < 0.0001). In the subset of osteoporotic femurs, treatment increased failure load by 26% and work to failure by 45% (p < 0.01 for both). Treatment did not significantly affect stiffness in any group. These findings provide evidence that local delivery of the triphasic calcium-based implant in the proximal femur is technically feasible and provides immediate biomechanical benefit. Our results provide strong rationale for additional studies investigating the utility of this approach for reducing the risk of hip fracture. © 2019 The Authors.

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
INTRODUCTION Despite growing rates of fragility fractures, there has been a lack of research investigating the risk and characteristics of recurrent fragility fractures. METHODS The Medicare Standard Analytic Files database was used to identify patients from 2005 to 2009 who were older than 65 years, had a diagnosis of osteoporosis or osteopenia, and sustained a fragility fracture of the proximal humerus, distal radius, hip, ankle, or vertebral column. The incidence and type of recurrent fragility fracture were tracked over a 36-month period. RESULTS A total of 1,059,212 patients had an initial fragility fracture from 2005 to 2009. Of these patients, 5.8% had a subsequent fragility fracture within 1 year for their initial fracture, 8.8% within 2 years, and 11.3% within 3 years. At 3-year follow-up, hip fractures were the most common type of subsequent fracture, regardless of the initial fracture type (6.5%, P < 0.001). Vertebral compression and proximal humerus fractures (13.8% and 13.2%, respectively) were most likely to be associated with a recurrent fragility fracture. CONCLUSION Patients who have any type of fragility fracture have a notable risk of subsequent fractures within 3 years, especially hip fractures. These patients should be evaluated and treated for underlying risks factors, including osteoporosis and/or osteopenia. LEVEL OF EVIDENCE Retrospective, level III.

Abstract
Purpose Internal fixation using compression hip screws (CHS) and traction tables placing patients in the supine position is a gold standard option for treating intertrochanteric fractures; however, at our institution, we approach this treatment with patients in a lateral decubitus position. Here, the results of 100 consecutive elderly (i.e., ≥45 years of age) patients who underwent internal fixation with CHS in lateral decubitus position are analyzed. Materials and Methods Between March 2009 and May 2011, 100 consecutive elderly patients who underwent internal fixation with CHS for femoral intertrochanteric fracture were retrospectively reviewed. Clinical outcomes (i.e., Koval score, Harris hip score [HHS]) and radiographic outcomes (i.e., bone union time, amount of sliding of lag screw, tip-apex distance [TAD]) were evaluated. Results Clinical assessments revealed that the average postoperative Koval score decreased from 1.4 to 2.6 (range, 0–5; P<0.05); HHS was 85 (range, 72–90); and mean bone union time was 5.0 (range, 2.0–8.2) months. Radiographic assessments revealed that anteroposterior average TAD was 6.95 (range, 1.27–14.63) mm; lateral average TAD was 7.26 (range, 1.20–18.43) mm; total average TAD was 14.21 (range, 2.47–28.66) mm; average lag screw sliding was 4.63 (range, 0–44.81) mm; and average angulation was varus 0.72°(range, −7.6°−12.7°). There were no cases of screw tip migration or nonunion, however, there were four cases of excessive screw sliding and six cases of varus angulation at more than 5° Conclusion CHS fixation in lateral decubitus position provides favorable clinical and radiological outcomes. This technique is advisable for regular CHS fixation of intertrochanteric fractures.

Abstract
UNLABELLED A systematic review and meta-analysis was conducted on the prevalence of osteoporosis in the Eastern Mediterranean Region. The overall pooled prevalence of osteoporosis was 24.4%. The prevalence has increased significantly over the recent years. The highest pooled prevalence was in Saudi Arabia (32.7%), and the lowest was in Kuwait (15.1%). PURPOSE To conduct a systematic review and meta-analysis on the prevalence of osteoporosis in the Eastern Mediterranean Region (EMR), as defined by the World Health Organization. METHODS We included all observational studies reporting the prevalence of osteoporosis among general population. We searched literatures from the databases of PubMed, Scopus, Web of Science, and Index Medicus for the EMR published between January 2000 and December 2017 with no restriction of language. Two reviewers independently contributed in study selection and data extraction. STATA software was used for analyzing the collected data. RESULTS A total of 1692 citations were retrieved. After excluding the irrelevant articles, 36 eligible studies were included. The overall pooled prevalence rate of osteoporosis in the EMR on 31,593 participants was 24.4% (95% confidence interval [CI], 20.4-28.4). Based on femoral densitometry, the prevalence of osteoporosis was 16.8% (95% CI, 9.5-24.2), and based on spinal densitometry, it was 24.3% (95% CI, 19.4-29.2). The pooled prevalence in males was 20.5% (95% CI, 10.5-30.5), compared with 24.4% (95% CI, 20.2-28.6) in females. The prevalence rate was significantly higher in 2007-2015 (32.7%; 95% CI, 25.1-40.3) than in 2000-2006 (19.8%; 95% CI, 12.5-27). CONCLUSIONS Our findings indicate a considerable prevalence of osteoporosis among the people of the EMR. The prevalence has increased during recent years, showing that osteoporosis is becoming a critical health problem in this region. Prevention and control measures need to be implemented by health service authorities.

Abstract
INTRODUCTION: Hip fractures represent an enormous challenge for our health care system. The aim of this randomised controlled trial was to assess both efficacy and safety of a novel device called Prevention Nail System (PNS) and developed for the surgical prevention of a contralateral femoral neck fracture (FNF) in elderly osteoporotic patients. METHODS: Primary outcome was to evaluate, in patients suffering from osteoporotic FNF, the effectiveness of PNS in reducing the incidence of a contralateral hip fracture. Secondary outcome was to evaluate the safety of this device therefore intra- and postoperative complications were recorded. RESULTS: 72 patients, with an age ⩾65 years old, were enrolled (38 study group (group A) and 34 control group (group B). 3 and 5 contralateral FNF were recorded respectively in group A and B. An interim analysis showed a non-effectiveness of the device therefore enrollment was suspended. DISCUSSION: In all group A failures a difficult positioning of the PNS was recorded: surgical techniques errors may have affected the result. Nevertheless, it is improbable to hypothesise that, without substantial modifications to the PNS design, this could significantly reduce the incidence of FNF. Considering that current pharmacological approach can achieve, at best, a marginal reduction in FNF especially in patients at high risk, complementary approaches to provide immediate prevention of hip fractures may need to be developed.

Abstract
PURPOSE OF REVIEW Cortical bone mapping (CBM) is a technique for measuring localised skeletal changes from computed tomography (CT) images. It can provide measurements with accuracy surpassing the underlying imaging resolution. CBM can detect changes in several properties of the cortex, with no prior assumptions about the likely location of said changes. This paper summarises the theory behind CBM, discusses its strengths and limitations, and reviews some studies in which it has been applied. RECENT FINDINGS CBM has revealed associations between fracture risk and cortical properties in specific regions of the proximal femur which present feasible therapeutic targets. Analyses of several pharmaceutical and exercise interventions quantify effects that are distinct both in location and in the nature of the micro-architectural changes. CBM has illuminated age-related changes in the proximal femur and has recently been applied to other bones, as well as to the assessment of cartilage. The CBM processing pipeline is designed primarily for large cohort studies. Its main impact thus far has not been in the realm of clinical practice, but rather to improve our fundamental understanding of localised bone structure and changes.

Abstract
Background Hip fractures increase the risks of mortality and major morbidity in the elderly. Hip fractures are associated with chronic pain, reduced mobility, disability and increasing dependence. We evaluated the direct costs incurred to the Israeli healthcare system in 2013 as a result of hip fracture injuries in elderly patients. Methods Hip fractures costs evaluation consisted of first-year and long-term direct costs. Data on the incidence of hip fractures resulting in hospitalizations were retrieved from the Israeli Ministry of Health’s (MOH) Central Database of Hospital Admissions. Hospitalization, rehabilitation and nursing utilization rates and costs were estimated based on the professional literature and according to the MOH’s price list. Results During 2013, 6285 elderly patients were hospitalized in Israel due to hip fractures. Direct costs of hip fracture, comprising hospitalization, rehabilitation and nursing costs incurred during the first year after the injury, were estimated at 454 million New Israeli Shekels (NIS; 83,841 NIS per person). Long-term nursing care costs in 2013 were 265 million NIS, with an average cost of approximately 49,000 NIS for 1600 elderly persons receiving long-term nursing care as a result of a hip fracture. Overall, the total direct costs of hip fracture in the elderly population in Israel in 2013 were 719 million NIS. Conclusions The direct costs of hip fractures in Israel among the elderly are approximately 719 million NIS per year. The majority of costs are associated with the first year following the injury. To reduce healthcare costs in Israel, changes in the country’s healthcare policy on hip fractures are required. For example, there is a need for a program for detecting high- risk populations, and for early intervention following the injury.

Abstract
This paper proposes a discrete particle model based on the random-walk theory for simulating cement infiltration within open-cell structures to prevent osteoporotic proximal femur fractures. Model parameters consider the cement viscosity (high and low) and the desired direction of injection (vertical and diagonal). In vitro and in silico characterizations of augmented open-cell structures validated the computational model and quantified the improved mechanical properties (Young's modulus) of the augmented specimens. The cement injection pattern was successfully predicted in all the simulated cases. All the augmented specimens exhibited enhanced mechanical properties computationally and experimentally (maximum improvements of 237.95 ± 12.91% and 246.85 ± 35.57%, respectively). The open-cell structures with high porosity fraction showed a considerable increase in mechanical properties. Cement augmentation in low porosity fraction specimens resulted in a lesser increase in mechanical properties. The results suggest that the proposed discrete particle model is adequate for use as a femoroplasty planning framework.

Abstract
Low-trauma fractures tend to cluster in time, and subsequent fractures have a role in increased morbidity and mortality in osteoporotic patients. The aim of this study was to identify the risk factors of short-term subsequent non-vertebral fracture (NVF). Patients were included from the Fracture Liaison Service (FLS) which provides assessment for osteoporosis to all in-hospital patients admitted for a low-trauma NVF in the Orthopaedics department. Location and date of occurrence of previous fractures, risk factors for osteoporosis and falls were collected. Bone mineral density was measured at the lumbar spine and total hip; presence of vertebral fractures was evaluated using vertebral fracture assessment (VFA). Nine hundred and fifty patients were included (84% women; 75±12years), with a mean T-score at the femoral neck of -2.3±1.0. Four hundred and sixty eight (49%) patients were in the FLS because of a hip fracture. Using multivariable analysis, the risk of being in the FLS with a previous fracture ≤3years before was associated with: history of fall in the year before the admission (OR=2.75, CI 95% 1.55-4.93), history of severe low-trauma NVF (OR=2.54; CI 95% 1.45-4.52), and BMI lower than 20kg/m2 (OR=2.45, CI 95% 1.25-4.87); age older than 78years-old was protective to the risk of re-fracture (OR=0.44, CI 95% 0.24-0.80). Some risk factors (age, history of fall and of previous severe non-vertebral fracture) can help in the selection of patients at high risk of refracture, who should receive the highest priority for a treatment.

Abstract
Osteoporosis is a silent disease with increasing prevalence due to the global ageing population. Decreased bone strength and bone quality is the hallmark of osteoporosis which leads to an increased risk of fragility fractures in elderly. It has been estimated that approximately ~50% of women will suffer during their lifetime from an osteoporotic fracture. This must be considered as a major health concern, as it has previously been established that fragility fracture has been associated with decreased quality of life due to increased disability, more frequent hospital admission and most importantly, osteoporotic fractures have been related to an augmented mortality risk. Anti-osteoporotic drugs are available for improving bone quality. Although there is access to these therapeutic options, there remain multiple unmet needs in the field of osteoporosis and fracture care, for example, the primary prevention of osteoporosis in young individuals (to reach a high peak bone mass), the optimization of the use of imaging techniques [dual-energy X-ray absorptiometry (DXA), vertebral fracture assessment (VFA) and new techniques measuring bone quality], the use of nonmedical treatment options and surgical techniques of fracture healing. In this review, we will discuss topics that play a role in the occurrence and prevention of fractures, and we give an overview of and insight into the critical issues and challenges around osteoporosis and fracture prevention.

Abstract
INTRODUCTION Major osteoporotic fractures are steadily increasing due to population aging. Programs of secondary prevention against refracture are essential to decrease morbidity and mortality and the cost for individuals and the society. Vitamin D supplementation and optimization of calcium intake are of a pivotal importance to start specific osteoporosis treatment and for its safety and efficacy. Cholecalciferol is the most widely employed drug for vitamin D supplementation. PURPOSE Aim of this study was to assess the trends in the use of vitamin D supplements containing cholecalciferol in the population of hip fracture patients older than 65 years, resident in the region of Tuscany (Italy) in the years 2011-2015 and to describe vitamin D status in a subgroup of this individuals directly referred to a bone clinic for further evaluation after hip osteoporotic fracture. METHODS Data were retrieved from the electronic anonymous regional administrative database administered by the Region of Tuscany (Italy) in the years 2011-2015 within the T.A.R.Ge.T. project (Trattamento Appropriato delle Rifratture Geriatriche in Toscana, i.e., "Appropriate treatment of geriatric refractures in Tuscany"), a program endorsed by the region itself. Data pertaining to cholecalciferol prescriptions and hospital discharge codes were retrieved and appropriately crossed to get data on the use of cholecalciferol supplements in patients before and after a hip fracture. A retrospective analysis was carried out in a subgroup of subjects (n 254) appropriately referred to the local fracture liaison service after the major osteoporotic fracture and vitamin D status in terms of serum 25(OH) vitamin D levels was assessed. RESULTS The majority of subjects experiencing a hip fracture (98.2% and 88.3% in 2011 and 2015, respectively) did not receive vitamin D supplements at the time of the fracture event. Although a trend in increase in prescriptions for cholecalciferol supplements could be observed in the years of the study, the percentage of treated individuals remained low even after the fracture, since only 30-35% of subjects receives cholecalciferol supplements at one year after the fracture. Cholecalciferol remained the most prescribed drug in this population, while a substantial decrease of cholecalciferol in association with calcium salts was observed. The use of high doses of cholecalciferol has decreased in this population, while diminished the use of the drops has been accompanied by an increase in prescriptions of single monthly dose supplements. CONCLUSIONS The correction of vitamin D inadequacy is preliminary to any treatment for osteoporosis and together with calcium may reduce fracture risk by itself. The prescription of vitamin D supplements is low in patients before and after a hip fracture in a Mediterranean region and despite the overall increase in vitamin use and abuse in the general population. Proper educational programs and active fracture liaison services are needed in order to bridge this gap.

Abstract
Osteoporosis represents a significant and increasing healthcare burden in Europe, but most patients at increased risk of fracture do not receive medication, resulting in a large treatment gap. Identification of patients who are at particularly high risk will help clinicians target appropriate treatment more precisely and cost-effectively, and should be the focus of future research. INTRODUCTION The purpose of the study was to review data on the identification and treatment of patients with osteoporosis at increased risk of fracture. METHODS A working group convened by the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis met to review current data on the epidemiology and burden of osteoporosis and the patterns of medical management throughout Europe. RESULTS In Europe in 2010, the cost of managing osteoporosis was estimated at €37 billion and notably the costs of treatment and long-term care of patients with fractures were considerably higher than the costs for pharmacological prevention. Despite the availability of effective treatments, the uptake of osteoporosis therapy is low and declining, in particular for secondary fracture prevention where the risk of a subsequent fracture following a first fracture is high. Consequently, there is a significant treatment gap between those who would benefit from treatment and those who receive it, which urgently needs to be addressed so that the burden of disease can be reduced. CONCLUSIONS Implementation of global fracture prevention strategies is a critical need. Future research should focus on identifying specific risk factors for imminent fractures, periods of high fracture risk, patients who are at increased risk of fracture and therapies that are most suited to such high-risk patients and optimal implementation strategies in primary, secondary and tertiary care.

Abstract
Osteoporosis is one of the most prevalent ageing-associated diseases that are soaring in the modern world. Although various aspects of the disease have been investigated to understand the bases of osteoporosis, the pathophysiological mechanisms underlying bone loss is still incompletely understood. Poldip2 is a molecule that has been shown to be involved in cell migration of vascular cells and angiogenesis. However, expression of Poldip2 and its regulation in bone cells were not known. Therefore, we examined the Poldip2 mRNA expression and the effects of bone regulators on the Poldip2 expression in osteoblasts. We found that Poldip2 mRNA is expressed in osteoblastic MC3T3-E1 cells. As FGF controls osteoblasts and angiogenesis, FGF regulation was investigated in these cells. FGF suppressed the expression of Poldip2 in MC3T3-E1 cells in a time dependent manner. Protein synthesis inhibitor but not transcription inhibitor reduced the FGF effects on Poldip2 gene expression in MC3T3-E1 cells. As for bone-related hormones, dexamethasone was found to enhance the expression of Poldip2 in osteoblastic MC3T3-E1 cells whereas FGF still suppressed such dexamethasone effects. With respect to function, knockdown of Poldip2 by siRNA suppressed the migration of MC3T3-E1 cells. Poldip2 was also expressed in the primary cultures of osteoblast-enriched cells and FGF also suppressed its expression. Finally, Poldip2 was expressed in femoral bone in vivo and its levels were increased in aged mice compared to young adult mice. These data indicate that Poldip2 is expressed in osteoblastic cells and is one of the targets of FGF. J. Cell. Biochem. 118: 1670-1677, 2017. © 2016 Wiley Periodicals, Inc.
