Abstract
Introduction Despite increasing recognition of atypical femoral fractures (AFFs), there's conflicting evidence about incidence, aetiology, and short-term outcomes of these injuries. This study reports the incidence of AFFs at our center and compares the early postoperative outcomes against typical femoral fractures (TFFs). Methods A retrospective observational cohort study of patients presenting to our trauma unit between November 2015 and July 2016 was undertaken. Inclusion criteria required radiologically confirmed proximal femoral fracture, which was then categorized as AFF or TFF. Primary outcome measures included length of stay, discharge destination, and 30-day mortality. Results Two hundred thirty-nine patients presented to our trauma unit over 9 months with either a fractured neck of femur or proximal femoral fracture. A total of 122 were identified as pertrochanteric, subtrochanteric, or proximal femoral shaft fractures of which 25 (20.5%) displayed atypical radiographic features consistent with AFF. The 2 groups were similar for average age (TFF 85.3 years vs AFF 85.0 years), gender (19% vs 16% male gender), American Society of Anaesthesiology grade (3.0 vs 3.0), cognitive score (abbreviated mental test score = 7.03 vs 7.08), and preinjury place of residence (88.9% vs 92.0% lived in own home). Typical fractures were fixed with either dynamic hip screw or intramedullary nailing, all atypical fractures were fixed with intramedullary nailing. There was no statistical difference between the 2 groups for length of stay (12.8 days vs 14.3 days; P > .05), discharge to preinjury residence (45.1% vs 36%; P > .05), or 30-day mortality (8.1% vs 12%; P > .05). Discussion In our predominantly geriatric population atypical radiographic features were observed in around 10% of patients presenting with proximal femoral fractures or fractured neck of femur. Previous studies have reported poor outcomes for pain, mobility, and length of stay after AFF. However, we observed no difference in short-term outcome measures when compared to patients with typical proximal femoral fracture patterns at our trauma unit. Conclusion With modern principles of trauma care outcomes achieved following AFFs may be equivalent to typical femoral fractures in the geriatric population.

Abstract
Introduction: Perioperative delirium in elderly hip fracture patients has been correlated with significant morbidity. The purpose of this study was to determine the preoperative risk factors for and short-term sequelae of postoperative delirium in geriatric hip fracture patients. Methods: We queried the American College of Surgeons National Surgical Quality Improvement Program to identify geriatric (≥65 years) patients who sustained operative hip fractures in 2016. Cohorts of patients with and without documented postoperative delirium were identified. Primary data on patient demographics and comorbidities were collected and correlated with postoperative complications and hip fracture outcome measures. Multivariate regression was used to compute risk-adjusted odds ratios (OR) of risk factors and sequelae of delirium. Results: In total, 8,439 geriatric hip fracture patients were identified of whom 2,569 patients (30.4%) had postoperative delirium. Age (OR 1.03 [1.02-1.04, p < 0.001), white race (OR 1.54 [1.19-2.00], p = 0.001), American Society of Anesthesiologists classification (OR 1.20 [1.07-1.36], p = 0.003), baseline dementia (OR 2.46 [2.11-2.86], p < 0.001), and preoperative delirium (OR 10.06 [8.12-12.45], p < 0.001) were independent risk factors for postoperative delirium in multivariate analysis. Patients with postoperative delirium had a significantly higher risk-adjusted 30-day mortality (12.0% vs. 4.8%, OR 2.22 [1.74-2.84], p < 0.001) and morbidity profile. Postoperative delirium was also independently associated with higher rates of discharge to (OR 1.65 [1.32-2.06], p < 0.001) and prolonged stay in (OR 1.79 [1.53-2.09], p < 0.001) an inpatient facility, hospital readmission (OR 1.94 [1.58-2.38], p < 0.001) and hospital length of stay (7.6 ± 5.0 vs. 6.1 ± 4.1 days, p < 0.001), as well as lower rates of immediate postoperative weight bearing (OR 0.73 [0.63-0.86], p < 0.001). Discussion: Postoperative delirium is a common occurrence in geriatric hip fractures with multiple risk factors. Delirium portends higher mortality and worse perioperative hospital-based outcomes. Conclusions: Multidisciplinary foreknowledge and management efforts are warranted to mitigate the risk of developing delirium, which strongly predicts perioperative morbidity, mortality, and hip fracture outcomes.

Abstract
Hip fractures result in significant morbidity and mortality in elders. Indicators of frailty are associated with poor outcomes. Commonly used frailty tools rely on motor skills that cannot be performed by this population. We determined the association between the Charlson Comorbidity Score (CCS), intraoperative hypotension (IOH), and a geriatric medicine consult index (GCI) with short-term mortality in hip fracture patients. A retrospective cohort study was conducted at a single institution over a 2-year period. Patients aged 65 years and older who sustained a hip fracture following a low-energy mechanism were identified using billing records and our orthopedic fracture registry. Medical records were reviewed to collect demographic data, fracture classification and operative records, calculation of CCS, intraoperative details including hypotension, and assessments recorded in the geriatric consult notes. The GCI was calculated using 30 dichotomous variables contained within the geriatric consult note. The index, ranging from 0 to 1, included markers for physical and cognitive function, as well as medications. A higher GCI score indicated more markers for frailty. One hundred eight patients met inclusion criteria. Sixty-four (59%) were females and the average age was 77.3 years. Thirty-five (32%) patients sustained femoral neck fractures, and 73 (68%) patients sustained inter-/pertrochanteric hip fractures. The 30-day mortality was 6%; the 90-day mortality was 13%. The mean GCI was 0.30 in the 30-day survivor group as compared to 0.52 in those who died. The mean GCI was 0.28 in patients who were alive at 90 days as compared to 0.46 in those who died. In contrast, the CCS and IOH were not associated with 30- or 90-day mortality. In our older hip fracture patients, an index calculated from information routinely obtained in the geriatric consult evaluation was associated with 30- and 90-day mortality, whereas the CCS and measures of IOH were not.

Abstract
Objectives Osteoporosis is a common skeletal disorder characterized by decreased bone mass and increased susceptibility to fractures, which are associated with pain and decrease in physical function, social function, and well-being, which are all aspects of quality of life (QoL). The purpose of this study was to evaluate the burden of osteoporosis and fragility fractures in Romanian postmenopausal women from Cluj County using the 36-Item Short Form Health Survey (SF-36) and Quality of life questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) questionnaires. Materials and methods An analytical cross-sectional study on 364 postmenopausal women was carried out between June 2016 and August 2017 in the Clinical Rehabilitation Hospital in Cluj-Napoca, Cluj County, Romania. Data were collected by interview and from the medical documents: clinical and demographic data, personal medical history, risk factors for osteoporosis, and bone mineral density at the lumbar spine and femur. The patients included in the study were asked to complete the Romanian versions of the SF-36 and QUALEFFO-41 questionnaires. Results Women with osteoporosis had significantly lower scores in the SF-36 domains (P<0.001) than healthy controls. In the osteoporosis group, a significant association was found in the SF-36 pain domain, where women with a history of fracture had higher scores (P=0.035). As for QUALEFFO-41, a statistical significance was found in the total score (P<0.05), revealing a significantly lower QoL in osteoporotic women with a history of fracture. Conclusion The SF-36 scores registered a loss of QoL in women with osteoporosis. The QUALEFFO-41 total score was significantly lower in the osteoporosis associated with fracture, revealing a lower health-related QoL in these patients.

Abstract
OBJECTIVE To determine research priorities in fragility fractures of the lower limb and pelvis which represent the shared priorities of patients, their friends and families, carers and healthcare professionals. DESIGN/SETTING A national (UK) research priority setting partnership. PARTICIPANTS Patients over 60 years of age who have experienced a fragility fracture of the lower limb or pelvis; carers involved in their care (both in and out of hospital); family and friends of patients; healthcare professionals involved in the treatment of these patients including but not limited to surgeons, anaesthetists, paramedics, nurses, general practitioners, physicians, physiotherapists and occupational therapists. METHODS Using a multiphase methodology in partnership with the James Lind Alliance over 18 months (August 2016-January 2018), a national scoping survey asked respondents to submit their research uncertainties. These were amalgamated into a smaller number of research questions. The existing evidence was searched to ensure that the questions had not been answered. A second national survey asked respondents to prioritise the research questions. A final shortlist of 25 questions was taken to a multistakeholder workshop where a consensus was reached on the top 10 priorities. RESULTS There were 963 original uncertainties submitted by 365 respondents to the first survey. These original uncertainties were refined into 88 research questions of which 76 were judged to be true uncertainties following a review of the research evidence. Healthcare professionals and other stakeholders (patients, carers, friends and families) were represented equally in the responses. The top 10 represent uncertainties in rehabilitation, pain management, anaesthesia and surgery. CONCLUSIONS We report the top 10 UK research priorities in patients with fragility fractures of the lower limb and pelvis. The priorities highlight uncertainties in rehabilitation, postoperative physiotherapy, pain, weight-bearing, infection and thromboprophylaxis. The challenge now is to refine and deliver answers to these research priorities.

Mortality After Complex Displaced Proximal Humerus Fractures in Elderly Patients: Conservative Versus Operative Treatment With Reverse Total Shoulder Arthroplasty. Geriatr Orthop Surg Rehabil 2018; 9:2151459318795241.

Abstract
Introduction Proximal humerus fractures (PHFs) are a common fragility fracture and have been shown to increase mortality in elderly patients. In the last decade, reverse total shoulder arthroplasty (RTSA) was introduced as a reliable operative treatment option for this indication. In other fragility fractures, most notably hip fractures, urgent surgical treatment can reduce mortality. The purpose of this study is to evaluate whether treatment with RTSA can reduce 1-year mortality in elderly patients with complex displaced PHFs. Materials and Methods A retrospective study was performed to compare 1-year mortality between 2 groups of elderly patients (>75 years old) who presented to a level 1 trauma center emergency department with complex displaced PHFs. The conservative treatment group (n = 83; mean age, 83.7 years) presented from 2008 to 2010 when RTSA was not yet available, and treatment was nonoperative. The surgical treatment group (n = 62; mean age, 82.2 years) presented from 2012 to 2015 and underwent RTSA. Results One-year mortality was 8.1% (male 7.1%; female 8.3%) in the surgical treatment group and 10.8% (male 18.8%; female 9.0%) in the conservative treatment group. The reduction in mortality in the surgical treatment group was not significant (entire cohort P = .56; males P = .35; females P = .59). Discussion Recent studies failed to show better functional results after surgical treatment with RTSA when compared to conservative treatment. This study suggests that a benefit of surgical treatment with RTSA that was not examined until now might exist-a reduction in the increased mortality risk associated with PHFs. Conclusions There was no significant difference in 1-year mortality between the groups, although there was a trend showing lower mortality with RTSA, mostly in men. Further studies with larger populations and longer follow-up times are needed to determine whether this trend is of clinical significance.

Abstract
PURPOSE OF REVIEW This article reviews recent publications on the effect of type 1 diabetes (T1D) on fracture risk, bone mineral density (BMD), bone structure, and bone tissue quality. Possible fracture prevention strategies for patients with T1D have also been reviewed. RECENT FINDINGS T1D is associated with substantially elevated fracture risk and modestly low BMD at the femoral neck. However, BMD alone does not explain higher observed fracture risk in T1D. T1D also affects bone macro- and microstructure, characterized by thinner cortices and trabecular bone changes such as thinner and more widely spaced trabeculae. Structural bone deficit is pronounced in the presence of microvascular complications. Tissue-level changes, such as accumulation of advanced glycation endproducts, detrimental alterations of the mineral phase because of low bone turnover, and occlusion of vascular channels in bone by mineralized tissue, are implicated in pathophysiology of bone fragility in T1D. There are no guidelines on screening and prevention of osteoporotic fractures in T1D. SUMMARY More studies are needed to understand the influence of T1D on structural bone quality and tissue material properties. There is a need for a prospective study to evaluate better screening strategies for diagnosis and treatment of osteoporosis in T1D.

Abstract
The Influence of Protein on the Prevention of Fragility Fractures Among Senior Adults Abstract. The aim of this review article is to discuss protein intake in senior adults at risk for fragility fractures as a modifiable factor for fracture prevention. Proteins are building blocks of the bone matrix and the muscles. This dual function fits in with the concept of prevention of fragility fractures in senior adults aimed at reducing both bone loss and falls. In older adults, a protein-rich diet could be another simple and effective way to promote bone and muscle health, in addition to the established recommendations for adequate vitamin D and calcium intake.

Abstract
Background Elderly patients with low-energy hip fractures have high rates of morbidity and mortality, but it is not well known how often concurrent upper extremity fractures occur and how this impacts outcomes. We used the National Trauma Databank (NTDB), the largest aggregation of US trauma registry data available, to determine whether patients with concurrent upper extremity and hip fractures have worse outcomes than patients with hip fractures alone. Methods We accessed the NTDB to identify patients aged 65 to 100 who sustained a hip fracture. The cohort was then narrowed to include only patients who sustained their injury in a fall and had an injury severity score indicating hip fracture as the most severe injury. We then analyzed this group to assess the impact of a simultaneous upper extremity fracture on length of stay, in-hospital mortality, and discharge disposition. Results From 2007 to 2014, a total of 231,299 patients aged 65 to 100 were identified as having a hip fracture. The narrowed cohort with fall as the mechanism and hip fracture as the most severe injury included 193,862 patients. Of these, 12,618 patients sustained a concomitant upper extremity fracture (6.5%). Compared to isolated hip fractures, patients with a concomitant upper extremity fracture had higher odds of death in the hospital (odds ratio [OR] = 1.3; 95% confidence interval = 1.2-1.4), were less likely to be discharged to home as compared to a skilled facility (OR = 0.73; 95% confidence interval = 0.68-0.78), and had a significantly longer average length of stay (7.1 vs 6.4 days, P < .001). Conclusions We found a 6.5% prevalence of concomitant upper extremity fractures in patients aged 65 to 100 with a hip fracture sustained after a fall where the hip fracture was the most severe injury. These patients had a higher risk of in-hospital mortality, were less likely to be discharged to home, and had longer average length of stay.

Abstract
Introduction: There is a projected exponential increase in the number of hip fractures in the United States. Trends in patient demographics and the role of total hip arthroplasty (THA) and its associated outcomes following hip fractures surgery have not been well studied. Methods: Patients with proximal femur fractures between 1990 and 2007 were identified in the National Hospital Discharge Survey database. Demographics, comorbidities, perioperative complications, and discharge status for patients undergoing THA, hemiarthroplasty, or internal fixation were examined. Multivariable regression was performed to determine independent risk factors for perioperative complications. Results: Between 1990 and 2007, there was a statistically significant increase in patient age, adverse events, medical comorbidities, surgical complications, medical complications, and nonroutine discharge across all surgical treatment modalities. In the same time period, the utilization of THA for all fracture types decreased significantly. Discussion: Total hip arthroplasty was found to be an independent risk factor for perioperative complications. Orthopedic surgeons should be aware that the hip fracture population continues to get older, with more medical comorbidities and are at higher risk for perioperative complications. Conclusion: Total hip arthroplasty is associated with a higher rate of perioperative complications in the hip fracture population.

Abstract
Introduction: Proximal humerus fractures are common in the elderly. The evaluation and management of these injuries is often controversial. The purpose of this study is to review recent evidence and provide updated recommendations for treating proximal humerus fractures in the elderly. Methods: A literature review of peer-reviewed publications related to the evaluation and management of proximal humerus fractures in the elderly was performed. There was a focus on randomized controlled trials and systematic reviews published within the last 5 years. Results: The incidence of proximal humerus fractures is increasing. It is a common osteoporotic fracture. Bone density is a predictor of reduction quality and can be readily assessed with anteroposterior views of the shoulder. Social independence is a predictor of outcome, whereas age is not. Many fractures are minimally displaced and respond acceptably to nonoperative management. Displaced and severe fractures are most frequently treated operatively with intramedullary nails, locking plates, percutaneous techniques, or arthroplasty. Discussion: Evidence from randomized controlled trials and systematic reviews is insufficient to recommend a treatment; however, most techniques have acceptable or good outcomes. Evaluation should include an assessment of the patient’s bone quality, social independence, and surgical risk factors. With internal fixation, special attention should be paid to medial comminution, varus angulation, and restoration of the calcar. With arthroplasty, attention should be paid to anatomic restoration of the tuberosities and proper placement of the prosthesis. Conclusion: A majority of minimally displaced fractures can be treated conservatively with early physical therapy. Treatment for displaced fractures should consider the patient’s level of independence, bone quality, and surgical risk factors. Fixation with percutaneous techniques, intramedullary nails, locking plates, and arthroplasty are all acceptable treatment options. There is no clear evidence-based treatment of choice, and the surgeon should consider their comfort level with various procedures during the decision-making process.

Abstract
Nearly 1 in every 3 Americans ride bicycles each year, but only 20% of the reported 100 million cyclists ride on a weekly basis. Bicycling is a common form of transportation and recreation and has gained popularity among the elderly patients. In recent years, the number of elderly cyclists has increased steadily and studies have cited ease of use, need for exercise, and enjoyment as important contributing factors. The benefits of physical activity on health is well-documented, and elderly individuals are encouraged to remain active to reduce the progression of age-related weakness and loss of muscle mass. Safety concerns, however, have been a prevalent public health issue. According to the Center for Disease Control and Prevention, elderly and teenage cyclists account for the highest number of head injuries and fatalities among all cyclists. Safety measures that include wearing protective gear such as helmets and choosing the appropriate bicycle have been recommended to minimize the risk of sustaining injuries while riding. Despite these concerns, bicycling has remained a popular and exciting activity for the elderly patients.

Abstract
INTRODUCTION Introduction: Adequate calcium and vitamin D from diet and supplementation is recommended for elderly hip fracture patients. Using data from the multinational hip fracture arthroplasty trial (HEALTH), we determined the proportion of patients who consistently took vitamin D and calcium and which characteristics/prescribing practices were associated with consistency of supplement use. METHODS HEALTH is a multicenter randomized trial of elderly hip fracture patients treated with hemi-arthroplasty and total hip arthroplasty. Patients were categorized as consistent users, inconsistent users, or nonusers of calcium and vitamin D. We used multinomial regression to determine the characteristics associated with calcium and vitamin D use. RESULTS 603 HEALTH participants were included in the analysis. 34.7% of patients never took vitamin D within 12 months after surgery, 26.2% took vitamin D inconsistently, and 39.1% took vitamin D consistently. 36.0% of patients never took calcium within 12 months after surgery, 28.4% took calcium inconsistently, and 35.7% took calcium consistently. There was great variation in prescribed/recommended doses. Compared to nonusers, consistent users of the supplements were more likely to be female, North American, prescribed/recommended vitamin D and/or calcium postoperatively, and presented to a facility with comprehensive fragility fracture protocols. CONCLUSIONS A low proportion of elderly hip fracture patients are consistently taking vitamin D and calcium, which may contribute to poorer bone health. Surgeons should be educated to prescribe/ recommend vitamin D and calcium, institutions should develop comprehensive fragility fracture protocols and patient education strategies to ensure that patients with osteoporosis receive bone health management beyond fracture care.

Abstract
Zoledronic acid (ZA), a highly potent intravenous bisphosphonate (BP), has been increasingly used in children with primary and secondary osteoporosis due to its convenience of shorter infusion time and less frequent dosing compared to pamidronate. Many studies have also demonstrated beneficial effects of ZA in other conditions such as hypercalcemia of malignancy, fibrous dysplasia (FD), chemotherapy-related osteonecrosis (ON) and metastatic bone disease. This review summarizes pharmacologic properties, mechanism of action, dosing regimen, and therapeutic outcomes of ZA in a variety of metabolic bone disorders in children. Several potential novel uses of ZA are also discussed. Safety concerns and adverse effects are also highlighted.

[PMID: 29560284 PMCID: PMC5851103 DOI: 10.1177/2151458517728155] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Revised: 07/22/2017] [Accepted: 07/22/2017] [Indexed: 11/15/2022] Open
Abstract
Background Known possible consequences of proximal humerus fractures include impaired shoulder function, decreased independence, and increased risk for mortality. The purpose of this report is to describe the survival and independence of elderly patients with fractures of the proximal humerus, treated in our institution, relative to patient characteristics and treatment method. Methods Retrospective cohort study from 2006 to 2012. Setting Community-based hospital with level 1 designation. Patients/Participants Three hundred nineteen patients ≥60 years who presented to the emergency department with an isolated fracture of the proximal humerus were either admitted to the inpatient ward for the organization and provision of immediate definitive care or discharged with the expectation of coordination of their care as an outpatient. Treatment was nonoperative or operative. Outcome Measures One- and 2-year mortality. Results Significant predictors of mortality at 1 year included Charlson Comorbidity Index (CCI; continuous, hazard ratio [HR] = 1.40; 95% confidence interval [CI]: 1.06-1.86), body mass index (BMI; <25 vs ≥25; HR = 3.43; 95% CI: 1.45-8.14), and American Society of Anesthesiologists (ASA) disease severity score (3-4 vs 1-2; HR = 4.48; 95% CI: 1.21-16.55). In addition to CCI and BMI, reliance on a cane/walker/wheelchair at the time of fracture predicted mortality at 2 years (vs unassisted ambulation; HR = 3.13; 95% CI: 1.59-5.88). Although the Neer classification of fracture severity significantly correlated with inpatient admission (P < .001), it was not significantly associated with mortality or with loss of living or ambulatory independence. Among admitted patients, 64% were discharged to a facility with a higher level of care than their prefracture living facility. Twenty percent of study patients experienced a loss in ambulatory status by at least 1 level at 1 year postfracture. Conclusion In a cohort of elderly patients with fractures of the proximal humerus, patient characteristics including comorbidities, ASA classification, and lower BMI were associated with increased mortality. Specifically, those admitted at the time of fracture and treated nonoperatively had the highest mortality rate and, likely, represent the frailest cohort. Those initially treated as outpatients and later treated operatively had the lowest mortality and, likely, represent the healthiest cohort. These data are inherently biased by prefracture comorbidities but help stratify our patients' mortality risk at the time of injury.

Geriatr Orthop Surg Rehabil 2017; 8:166-172. [PMID: 28835874 PMCID: PMC5557201 DOI: 10.1177/2151458517722608] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Revised: 06/01/2017] [Accepted: 06/14/2017] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVE To investigate the reliability of a clinically applicable method of dynamometry to assess and monitor hip abductor muscle strength in older persons. DESIGN Bilateral isometric hip abductor muscle strength measured with a handheld dynamometer, patients supine with the contralateral hip positioned directly against a wall for stabilization. Reliability determined by comparing intra-assessor and inter-assessor results and comparison to a criterion standard (stabilized dynamometer with patients in the standing position). SETTING UniSA Nutritional Physiology Research Centre. PARTICIPANTS Twenty-one patients older than 65 years were recruited from the Royal Adelaide Hospital. MAIN OUTCOME MEASURES Intraclass correlation coefficients (ICCs), bias, and limits of agreement calculated to determine reliability. RESULTS Intra-assessor and inter-assessor ICCs were high (0.94 and 0.92-0.94, respectively). There was no intra-assessor bias and narrow limits of agreement (±2.4%). There was a small inter-assessor bias but narrow limits of agreement (0.6%-0.9% and ± 2.3%, respectively). There was a wide variation comparing results to the criterion standard (±5.0%-5.2% limits of agreement), highlighting problems attributed to difficulties that the test population had with the standing position used in the criterion standard test. CONCLUSIONS Testing older persons' hip abductor muscle strength while in the supine position with optimal pelvic stabilization using a handheld dynamometer is highly reliable. While further studies must be done to assess patients with specific pathologies, this test has potential application to monitor and evaluate the effects of surgical interventions and/or rehabilitation protocols for a variety of conditions affecting hip abductor function such as hip fractures and arthritis.

Abstract
Osteoporosis is a disease of weak bone and increased fracture risk caused by low bone mass and microarchitectural deterioration of bone tissue. The standard-of-care test used to diagnose osteoporosis, dual-energy x-ray absorptiometry (DXA) estimation of areal bone mineral density (BMD), has limitations as a tool to identify patients at risk for fracture and as a tool to monitor therapy response. Magnetic resonance imaging (MRI) assessment of bone structure and microarchitecture has been proposed as another method to assess bone quality and fracture risk in vivo. MRI is advantageous because it is noninvasive, does not require ionizing radiation, and can evaluate both cortical and trabecular bone. In this review article, we summarize and discuss research progress on MRI of bone structure and microarchitecture over the last decade, focusing on in vivo translational studies. Single-center, in vivo studies have provided some evidence for the added value of MRI as a biomarker of fracture risk or treatment response. Larger, prospective, multicenter studies are needed in the future to validate the results of these initial translational studies. LEVEL OF EVIDENCE 5 Technical Efficacy: Stage 5 J. MAGN. RESON.

Abstract
Most osteoporotic patients complain of back pain one year after a fragility vertebral fracture and the frequency of chronic back pain increases with increasing age. The use of the lowest effective dose of an analgesic which is able to control symptoms seems to be a possible solution in order to limit potential side effects in multi-treated elderly patients. Non-steroidal anti-inflammatory drugs (NSAIDs) have a proven efficacy in the treatment of back pain associated with fragility vertebral fractures and diclofenac is available at low-dose subcutaneous injective formulation. This is the rational of ImPAVeDic study, acronym of Improvement of back Pain Associated with fragility Vertebral fractures with low-dose Diclofenac, an observational study that will be performed in a group of 50 elderly (≥ 65 years), male and female osteoporotic patients with symptomatic fragility vertebral fractures. The objective of the study is to evaluate the improvement of back pain in the study population treated with low-dose diclofenac and regularly monitored for 2-6 months. Visual Analogic Scale (VAS) and Numerical Rating Scale (NRS) will be used for pain monitoring. The reduction of the risk of occurrence of drug side effects can favour the optimization of elderly patients' care.

Abstract
PURPOSE Osteogenesis imperfecta (OI) is a condition characterised by bone fragility and multiple fractures, which cause considerable morbidity in the affected patients. Most cases are associated with mutations in one of the type I collagen genes. Recently, bisphosponates have been used widely to reduce pain and the incidence of fragility fractures in OI in children, even though there have been concerns raised regarding the long-term complications of it due to their effect on the bone. The fragility fractures involving the neck of the femur in children with intramedullary rods in the femoral shaft are very difficult to treat. Although these fractures are frequently un-displaced, they require optimal internal fixation to achieve fracture union. The aim of this study was to assess the clinical and radiological outcomes of OI patients with intracapsular femoral neck fracture treated with headless compression screws. METHOD AND RESULTS At our institute, we identified seven patients (11 hips) with OI who underwent internal fixation with headless compression screws for a neck of femur fracture between June 2010 and Dec 2012. The time to fractures healing was on average 14 weeks (12 to 16). All patients gained their pre-injury ambulatory status. CONCLUSION It is very challenging and technically demanding for orthopaedic surgeons when treating the fragility fracture of the neck of femur in patients with intramedullary rod in the femoral shaft. The published data regarding the management of these complex conditions are very limited. We describe our experience with the technique of percutaneous headless compression screw fixation for treating the femoral neck fractures in OI patients.

Abstract
Introduction: According to the expected demographical changes, the number of elderly trauma patients will increase exponentially over the next decades. Different models of an interdisciplinary orthogeriatric care have been developed. But there is only limited evaluation of their benefit without clear and evidence-based results. In 2011, we monitored the results of our orthogeriatric combined management by conducting a 1-year follow-up. Methods: We treated 231 patients presenting a proximal femoral fracture on our orthogeriatric ward. We obtained the epidemiological data and the geriatric assessments from all these patients. One year after discharge, we sent them a written questionnaire. Primary end points were the mortality and the functional outcome, measured by Barthel score, the requirement of care, and the residential status. Results: One hundred sixty-seven (72%) of the 231 patients completed the follow-up. The average age at admission was 81.5 years (70-99 years). The mortality rate was 2.4% during hospital stay and 31.4% after 1 year. The average Barthel score was 44 points at the time of admission, 55 points at discharge, and 72 points after 1 year. Forty-five percent of the patients were in requirement of care at the time of their admission. At the 1-year follow-up, 63% of the patients had some form of care, thus showing an increase of 18%. At the moment of the fracture, 77% of the patients were living in their own home and 23% in a nursing home. After 1 year, the surviving patients show nearly unchanged conditions (75% own home vs 25% nursing home). Eighty-six percent of the patients coming from their own home were able to continue living there independently. Conclusion: The orthogeriatric care is successful in reducing the short-time mortality without showing any effect on 1-year mortality. But the surviving patients seem to benefit from an improved functional outcome.

Abstract
Introduction: Hip fracture is an increasingly common injury in the growing elderly population. The morbidity and mortality associated with this injury can be reduced by minimizing delays to surgical treatment. We describe the impact of a regional hospital service redesign project that utilized the principles of smart simplicity, a management strategy that lays emphasis on collaboration to achieve desired goals. Methods: Prior to the redesign, patients with hip fractures were taking an average of 72 hours for surgical treatment. A hip fracture working group was created to examine closely the process of hip fracture care, and a single key performance indicator (KPI) of “surgery within 48 hours” was adopted. This allowed identification of processes that could be clarified and streamlined, with the agreement of relevant stakeholders, in the creation of a new hip fracture pathway. Results: In the first 3 months of the pathway’s implementation, 16 of 18 patients had surgery within 48 hours of presentation. In a 6-month follow-up audit after 2 years of implementation, 36 of 39 patients were treated within 48 hours. This was significantly different to the time to surgery seen in the 12 months prior to the redesign (P < .001, Student t test). The mean time to surgery was reduced from 72 hours to 36 hours, a saving in an annual acute bed stay cost of A$152 000. Discussion: Decreased time to the operating room, the cost savings inherent to this, can be achieved with the introduction of the best standard of care. A redesign that mandates collaboration in achieving a single KPI has allowed a significant culture shift in the treatment of hip fractures in our institution in the months following its institution. Conclusion: Collaborative, multidisciplinary collaboration has facilitated a higher standard of care and demonstrated significant cost benefit.

Abstract
Objectives: This study aims to identify if wintertime surgery increases the mortality of the patients after hip fracture operations. Design: Retrospective observational cohort study. Setting: The data for this citywide retrospective observational cohort study came from Clinical Data Analysis Reporting System. Patient: This study included 35 409 patients with hip fracture operations from July 2005 to December 2013. Main Outcome Measures: Cox regression hazard model was used to estimate the independent effect of operation being performed in winter on the hazard of mortality. The hazard model included covariates found to be independent predictors of mortality: age, sex, surgical delay, and Charlson Comorbidity Index (CCI). Results: There was a seasonal variation with more hip fracture operations happening in the winter months. The 1-month, 6-month, 1-year, and 5-year mortality were 3%, 11%, 17%, and 47%, respectively. Operation performed in winter was associated with a higher hazard of mortality (hazard ratio [HR] 1.040; 95% confidence interval: 1.010-1.072; P = .009). The HR was greater with male sex (HR 1.786; P = .000), advanced age (≥85 years old: HR 2.819; P = .000), the longer surgical delay (HR 1.018; P = .000), and higher CCI (severe CCI group: HR 2.963; P = .000). Conclusion: Wintertime hip fracture surgery was associated with an increased hazard of mortality after adjusting for other known risk factors affecting mortality post hip fracture operations.

Abstract
OBJECTIVES Age and bone mineral density (BMD) are the most relevant determinants for public health authorities to govern the management of osteoporosis. The objectives of this study were to determine the age-related prevalence of osteopenia and osteoporosis according to WHO criteria and fragility fractures in middle-aged and older women. METHODS Women ≥40 years, who were referred to a menopause and osteoporosis outpatient clinic for BMD measurements, were assessed for patient characteristics, BMD and previous fragility fractures of the hip, the distal forearm and the vertebrae. Only records of their initial consultations were used for data analysis. RESULTS Between 1990 and 2012, 99,399 women, mean age 56.1 years, were referred to the clinic for BMD testing. Of the total population, 52.5% showed normal, 34.0% osteopenic and 13.5% osteoporotic BMD. Fragility fractures were reported by 6540 patients, with 3070 (47%) non-vertebral fractures, namely 2518 (38.5%) distal forearm and 552 (8.4%) hip fractures; 66.8% of patients with the non-vertebral fractures were <65 years. CONCLUSION The prevalence of osteoporosis and fragility fractures in middle-aged women, < 65 years, is hitherto under-recognized. Measuring BMD alone is not sufficient to identify patients at risk for fractures. Supplemental screening for clinical risk factors already during perimenopause may be advantageous.

Abstract
PURPOSE To examine whether premenopausal women with distal radius fractures (DRF) have lower levels of 25-hydroxyvitamin D (25[OH]D) and increased levels of serum bone turnover markers (BTM) compared with control subjects without fracture. METHODS Premenopausal women with DRF (n = 20) were prospectively enrolled and compared with age-matched individuals without a fracture (n = 20). Outcome measures included serum levels of 25(OH)D, parathyroid hormone (PTH), markers of bone formation (osteocalcin [OC], N-terminal extension propeptide of type I collagen [P1NP], and bone-specific alkaline phosphatase [BSAP]), and markers of bone resorption (C-terminal telopeptide of type I collagen [CTX]). We assessed associations between BTM and DRF with conditional logistic regression and the utility of markers for fracture prediction with a receiver operator characteristic analysis. RESULTS The fracture group and control group were comparable in terms of age at menarche and BMI. Patients who had fractures had significantly greater levels of OC and P1NP, and demonstrated a nonsignificant increase in CTX. Levels of 25(OH)D, PTH, and BSAP were similar between groups. Conditional logistic regression revealed independent associations between DRF and increased levels of OC and CTX. Levels of 25(OH)D and PTH were not associated with DRF. Receiver operator characteristic analyses demonstrated moderate performance for OC, P1NP, BSAP, and CTX in predicting DRF. CONCLUSIONS Levels of 25(OH)D were not associated with DRF in premenopausal women. However, patients with DRF had increased levels of BTM of formation and resorption. Bone turnover markers may be helpful in predicting future fragility fractures in premenopausal women. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.
