[PMID: 39040625 PMCID: PMC11260344 DOI: 10.1016/j.jcot.2024.102471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 06/06/2024] [Accepted: 06/24/2024] [Indexed: 07/24/2024] Open
Abstract
Objective This review evaluated the outcomes of rhombic versus inverted triangle configuration fixation of femoral neck fractures. Methods Six databases, PubMed, Embase, Scopus, Web of Science, Cochrane Library databases, and China National Knowledge Infrastructure (CNKI), were comprehensibly searched for the comparative studies of two configurations (rhombic versus inverted triangle) of neck femur fracture fixation. Ultimately seven studies were included in this systematic review for qualitative and quantitative analysis. A meta-analysis was performed with the software RevMan 5.4.1. Results Fewer nonunion (OR 0.46 with 95 % CI 0.23, 0.94; p = 0.03), and early full weight bearing (MD -3.09 with 95 % CI -5.41, -0.77; p = 0.009) were seen in the rhombic than in the inverted configuration; however, a better hip function (MD 3.72 with 95 % CI 0.99, 6.44; p = 0.008), and lesser less blood loss (MD 3.84 with 95 % CI 1.19, 6.49; p = 0.004) during surgery were found in the inverted triangle configuration. There was no difference between the two fixation configurations regarding the duration of surgery, fracture union time, overall complications, femoral neck shortening, length of hospital stay, fluoroscopy times, and incision size. Conclusion The rhomboid configuration showed fewer non-union, early weight bearing, better hip function and comparable complications rate than the inverted triangle configuration; however, there was more blood loss intraoperatively than inverted triangle configuration. Hence, the addition of a fourth screw in the rhombic configuration have an added advantage over the inverted triangle configuration in femoral neck fracture.

Non-cannulated versus cannulated cancellous screws for the internal fixation of femoral neck fractures in osteoporotic patients: A single-blind randomized clinical trial. J Orthop 2024; 51:32-38. [PMID: 38299065 PMCID: PMC10825919 DOI: 10.1016/j.jor.2023.11.074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 11/26/2023] [Accepted: 11/28/2023] [Indexed: 02/02/2024] Open
Abstract
Background The incidence of femoral neck fractures in osteoporotic patients is rising worldwide and is associated with significant increases in healthcare and social costs, as well as dependency. Improving minimally invasive treatment strategies, including internal fixation with screws, can result in favorable clinical outcomes and lesser incidence of complications, while preserving the hip. This study compared the outcomes of using non-cannulated cancellous screws (NCS) and cannulated cancellous screws (CS) in the internal fixation of undisplaced intracapsular femoral neck fractures (UIFNF) of osteoporotic patients of Iranian descent. Methods This randomized clinical trial was conducted on the patients referring to an institutional tertiary hospital in northwestern Iran between March 2020 and June 2021. The patients' preoperative, perioperative, and postoperative characteristics were evaluated for at least two years. Primary endpoints were defined as the incidence of hip-related complications, while secondary endpoints were assessed based on the patients' hip function using Harris Hip Score (HHS). Results Fifty-seven patients with osteoporosis and UIFNF were included in the final analysis, with 27 patients in the NCS group and 30 patients in the CS group. The surgical duration, the amount of intraoperative blood loss, and the frequency of C-arm were considerably lower in the CS group (p < 0.05). The incidence of implant failure was higher in the NCS group (p = 0.04). Screw migration occurred more frequently in the CS group (p = 0.03). The HHS values were significantly higher for the NCS group than those of the CS group at both the 1-year and 2-years of follow-up assessments (1 year, p = 0.007; 2 years, p = 0.001). Conclusion Fixation using CS was accompanied by enhanced perioperative outcomes and lower implant failure rates compared to the NCS group. However, patients in the NCS group posed a reduced risk of complications, including screw migration, and experienced a long-term improvement in HHS scores.

[PMID: 37730490 DOI: 10.1016/j.injury.2023.111018] [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: 07/18/2023] [Accepted: 09/02/2023] [Indexed: 09/22/2023]
Abstract
INTRODUCTION Pauwels Type III fractures are unstable and frequently treated with cannulated screws (CS) or dynamic hip screws (DHS). The newly developed talon-cannulated compression devices (TCCD) have the potential to provide rotational stability, mainly through their talon. The study investigates whether TCCD has mechanical advantages over conventional screws or can be as stable as DHS in a reverse triangle configuration for an unstable femoral neck fracture. MATERIAL AND METHODS After creating a standard Pauwels Type III unstable femoral neck fracture in 36 synthetic femur bones in cortical/hard cancellous bone density, 18 were reserved for dynamic-static tests, and 18 were used for torsional tests. Each group containing 18 synthetic bones was divided into three groups to apply three different fixation materials (CS, DHS, and TCCD), with six models in each group. The displacement amounts after dynamic-static tests were measured using the AutoCAD program according to the reference measurement criteria. During the dynamic tests, a series of photographs were taken. During the static tests, the beginning and post-test photographs were taken. Finally, torsional tests were performed until implant failure occurred in the synthetic femur. RESULTS In static axial loading tests, TCDD was found to be statistically superior to conventional CS in AL-BL distance (p = 0,014) and CL distance (p = 0,013) measurements, and there was no significant difference between the other groups. There was no significant difference between all groups in dynamic axial compression tests in any points of interest. In torsional tests, TCCD outperformed cannulated screws in stiffness (p = 0,001) and maximum torque (p = 0,001) categories, and they provided statistically significant superiority to DHS in yield torque (p<0,001) category. CONCLUSIONS Biomechanically, TCCD predominates conventional cannulated screws in femoral neck fractures. TCCD also has superior torsional properties than DHS in the yield torque category. Therefore, TCCD could be the implant of choice for unstable femoral neck fractures.

Abstract
BACKGROUND This cadaveric study seeks to determine whether skills acquired on the simulator translate to improved performance of the clinical task. We hypothesized that completion of simulator training modules would improve performance of percutaneous hip pinning. METHODS Eighteen right-handed medical students from two academic institutions were randomized: trained (n = 9) and untrained (n = 9). The trained group completed nine simulator-based modules of increasing difficulty, designed to teach techniques of placing wires in an inverted triangle construct in a valgus-impacted femoral neck fracture. The untrained group had a brief simulator introduction but did not complete the modules. Both groups received a hip fracture lecture, an explanation and pictorial reference of an inverted triangle construct, and instruction on using the wire driver. Participants then placed three 3.2 mm guidewires in cadaveric hips in an inverted triangle construct under fluoroscopy. Wire placement was evaluated with CT at 0.5 mm sections. RESULTS The trained group significantly outperformed the untrained group in most parameters (P ≤ 0.05). CONCLUSIONS The results suggest that a force feedback simulation platform with simulated fluoroscopic imaging using an established, increasingly difficult series of motor skills training modules has potential to improve clinical performance and might offer an important adjunct to traditional orthopaedic training.

Patients With Femoral Neck Fractures Are at Risk for Conversion to Arthroplasty After Internal Fixation: A Machine-learning Algorithm. Clin Orthop Relat Res 2022; 480:2350-2360. [PMID: 35767811 PMCID: PMC9653184 DOI: 10.1097/corr.0000000000002283] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Accepted: 05/31/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND Femoral neck fractures are common and are frequently treated with internal fixation. A major disadvantage of internal fixation is the substantially high number of conversions to arthroplasty because of nonunion, malunion, avascular necrosis, or implant failure. A clinical prediction model identifying patients at high risk of conversion to arthroplasty may help clinicians in selecting patients who could have benefited from arthroplasty initially. QUESTION/PURPOSE What is the predictive performance of a machine-learning (ML) algorithm to predict conversion to arthroplasty within 24 months after internal fixation in patients with femoral neck fractures? METHODS We included 875 patients from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial. The FAITH trial consisted of patients with low-energy femoral neck fractures who were randomly assigned to receive a sliding hip screw or cancellous screws for internal fixation. Of these patients, 18% (155 of 875) underwent conversion to THA or hemiarthroplasty within the first 24 months. All patients were randomly divided into a training set (80%) and test set (20%). First, we identified 27 potential patient and fracture characteristics that may have been associated with our primary outcome, based on biomechanical rationale and previous studies. Then, random forest algorithms (an ML learning, decision tree-based algorithm that selects variables) identified 10 predictors of conversion: BMI, cardiac disease, Garden classification, use of cardiac medication, use of pulmonary medication, age, lung disease, osteoarthritis, sex, and the level of the fracture line. Based on these variables, five different ML algorithms were trained to identify patterns related to conversion. The predictive performance of these trained ML algorithms was assessed on the training and test sets based on the following performance measures: (1) discrimination (the model's ability to distinguish patients who had conversion from those who did not; expressed with the area under the receiver operating characteristic curve [AUC]), (2) calibration (the plotted estimated versus the observed probabilities; expressed with the calibration curve intercept and slope), and (3) the overall model performance (Brier score: a composite of discrimination and calibration). RESULTS None of the five ML algorithms performed well in predicting conversion to arthroplasty in the training set and the test set; AUCs of the algorithms in the training set ranged from 0.57 to 0.64, slopes of calibration plots ranged from 0.53 to 0.82, calibration intercepts ranged from -0.04 to 0.05, and Brier scores ranged from 0.14 to 0.15. The algorithms were further evaluated in the test set; AUCs ranged from 0.49 to 0.73, calibration slopes ranged from 0.17 to 1.29, calibration intercepts ranged from -1.28 to 0.34, and Brier scores ranged from 0.13 to 0.15. CONCLUSION The predictive performance of the trained algorithms was poor, despite the use of one of the best datasets available worldwide on this subject. If the current dataset consisted of different variables or more patients, the performance may have been better. Also, various reasons for conversion to arthroplasty were pooled in this study, but the separate prediction of underlying pathology (such as, avascular necrosis or nonunion) may be more precise. Finally, it may be possible that it is inherently difficult to predict conversion to arthroplasty based on preoperative variables alone. Therefore, future studies should aim to include more variables and to differentiate between the various reasons for arthroplasty. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
BACKGROUND Fragility fractures of the hip are known to be followed frequently by subsequent fragility fractures, including second hip fractures. Data on subsequent fractures are available for aggregated index femoral neck and intertrochanteric femoral fractures, grouped generically as hip fractures, but not specifically for femoral neck fractures. There is increasing recognition that a subsequent fracture often occurs early after a hip fracture in the elderly, creating an emphasis on the concept of "imminent fracture risk." Since 2000, there have been many reports on the care gap in interventions after a fragility fracture, with concern regarding the slow uptake of appropriate systemic treatments designed to prevent a subsequent fracture in high-risk patients. METHODS As planned a priori, we performed an analysis of subsequent fractures after an index femoral neck fracture in 2 prospective clinical trials involving 2,520 patients from 90 sites on 5 continents. We recorded the incidence and time of occurrence of all secondary fragility fractures as well as the reported use of bone-protective medication in all subjects. RESULTS In the 24 months following the index femoral neck fracture, 226 (9.0%) of 2,520 patients sustained at least 1 subsequent fragility fracture, including 113 hip fractures (4.5%). The median interval from the index fracture to a subsequent fracture was approximately 9.0 months. Only 25.2% (634) of the 2,520 patients reported using bone-protective medications at any time during follow-up. Female patients, those with nondisplaced index fractures, and those treated with arthroplasty, were more likely to have received protective medication. CONCLUSIONS Subsequent fractures, including second hip fractures, occurred frequently and early following an index femoral neck fracture in 2 large global cohorts. Interventions to prevent a subsequent fracture were instituted in only 1 of 4 patients, even though a focused directive was included in both study protocols. LEVEL OF EVIDENCE Prognostic Level II .

Abstract
Abstract
Introduction
Anterior dislocations, the most common type of shoulder dislocation, are often complicated by subsequent instability. With recurrent dislocations there often is attrition of the labrum and progressive loss of the anterior bony contour of the glenoid. Treatment options for this pathology involve either soft tissue repair or bony augmentation procedure. The optimal management remains unknown and current clinical practice is highly varied.
Methods and analysis
The Shoulder instability Trial comparing Arthroscopic stabilization Benefits compared with Latarjet procedure Evaluation (STABLE) is an ongoing multi-centre, pilot randomized controlled trial of 82 patients who have been diagnosed with recurrent anterior shoulder instability and subcritical glenoid bone loss. Patients are randomized to either soft tissue repair (Bankart + Remplissage) or bony augmentation (Latarjet procedure). The primary outcome for this pilot is to assess trial feasibility and secondary outcomes include recurrent instability as well as functional outcomes up to two years post-operatively.
Conclusions
This trial will help to identify the optimal treatment for patients with recurrent shoulder instability with a focus on determining which treatment option results in reduced risk of recurrent dislocation and improved patient outcomes. Findings from this trial will guide clinical practice and improve care for patients with shoulder instability.
Trial registration
This study has been registered on http://www.ClinicalTrials.gov with the following identifier: ClinicalTrials.gov Identifier: NCT03585491, registered 13 July 2018, https://www.clinicaltrials.gov/ct2/show/NCT03585491?term=NCT03585491&draw=2&rank=1.
Ethics and dissemination
This study has ethics approval from the McMaster University/Hamilton Health Sciences Research Ethics Board (REB) (approval #4942). Successful completion will significantly impact the global management of patients with recurrent instability. This trial will develop a network of collaboration for future high-quality trials in shoulder instability.

Abstract
BACKGROUND Hip fractures are a major healthcare problem, presenting a huge challenge and burden to patients, healthcare systems and society. The increased proportion of older adults in the world population means that the absolute number of hip fractures is rising rapidly across the globe. The majority of hip fractures are treated surgically. This review evaluates evidence for types of internal fixation implants used in joint-preserving surgery for intracapsular hip fractures. OBJECTIVES To determine the relative effects (benefits and harms) of different implants for the internal fixation of intracapsular hip fractures in older adults. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Web of Science, Cochrane Database of Systematic Reviews, Epistemonikos, Proquest Dissertations and Theses, and National Technical Information Service in July 2020. We also searched clinical trials databases, conference proceedings, reference lists of retrieved articles and conducted backward-citation searches. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing implants used for internal fixation of fragility intracapsular proximal femoral fractures in older adults. Types of implants were smooth pins (these include pins with fold-out hooks), screws, or fixed angle plates. We excluded studies in which all or most fractures were caused by specific pathologies other than osteoporosis or were the result of a high energy trauma. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion. One review author extracted data and assessed risk of bias which was checked by a second review author. We collected data for seven outcomes: activities of daily living (ADL), delirium, functional status, health-related quality of life (HRQoL), mobility, mortality (reported within four months of surgery as early mortality, and at 12 months since surgery), and unplanned return to theatre for treating a complication resulting directly or indirectly from the primary procedure (such as deep infection or non-union). We assessed the certainty of the evidence for these outcomes using GRADE. MAIN RESULTS We included 38 studies (32 RCTs, six quasi-RCTs) with 8585 participants with 8590 intracapsular fractures. The mean ages of participants in the studies ranged from 60 to 84 years; 73% were women, and 38% of fractures were undisplaced. We report here the findings of the four main comparisons, which were between different categories of implants. We downgraded the certainty of the outcomes for imprecision (when data were available from insufficient numbers of participants or the confidence interval (CI) was wide), study limitations (e.g. high or unclear risks of bias), and inconsistency (when we noted substantial levels of statistical heterogeneity). Smooth pins versus fixed angle plate (four studies, 1313 participants) We found very low-certainty evidence of little or no difference between the two implant types in independent mobility with no more than one walking stick (1 study, 112 participants), early mortality (1 study, 383 participants), mortality at 12 months (2 studies, 661 participants), and unplanned return to theatre (3 studies, 736 participants). No studies reported on ADL, delirium, functional status, or HRQoL. Screws versus fixed angle plates (11 studies, 2471 participants) We found low-certainty evidence of no clinically important differences between the two implant types in functional status using WOMAC (MD -3.18, 95% CI -6.35 to -0.01; 2 studies, 498 participants; range of scores from 0 to 96, lower values indicate better function), and HRQoL using EQ-5D (MD 0.03, 95% CI 0.00 to 0.06; 2 studies, 521 participants; range -0.654 (worst), 0 (dead), 1 (best)). We also found low-certainty evidence showing little or no difference between the two implant types in mortality at 12 months (RR 1.04, 95% CI 0.83 to 1.31; 7 studies, 1690 participants), and unplanned return to theatre (RR 1.10, 95% CI 0.95 to 1.26; 11 studies, 2321 participants). We found very low-certainty evidence of little or no difference between the two implant types in independent mobility (1 study, 70 participants), and early mortality (3 studies, 467 participants). No studies reported on ADL or delirium. Screws versus smooth pins (seven studies, 1119 participants) We found low-certainty evidence of no or little difference between the two implant types in mortality at 12 months (RR 1.07, 95% CI 0.85 to 1.35; 6 studies, 1005 participants; low-certainty evidence). We found very low-certainty evidence of little or no difference between the two implant types in early mortality (3 studies, 584 participants) and unplanned return to theatre (5 studies, 862 participants). No studies reported on ADL, delirium, functional status, HRQoL, or mobility. Screws or smooth pins versus fixed angle plates (15 studies, 3784 participants) In this comparison, we combined data from the first two comparison groups. We found low-certainty evidence of no or little difference between the two groups of implants in mortality at 12 months (RR 1.04, 95% CI.083 to 1.31; 7 studies, 1690 participants) and unplanned return to theatre (RR 1.02, 95% CI 0.88 to 1.18; 14 studies, 3057 participants). We found very low-certainty evidence of little or no difference between the two groups of implants in independent mobility (2 studies, 182 participants), and early mortality (4 studies, 850 participants). We found no additional evidence to support the findings for functional status or HRQoL as reported in 'Screws versus fixed angle plates'. No studies reported ADL or delirium. AUTHORS' CONCLUSIONS There is low-certainty evidence that there may be little or no difference between screws and fixed angle plates in functional status, HRQoL, mortality at 12 months, or unplanned return to theatre; and between screws and pins in mortality at 12 months. The limited and very low-certainty evidence for the outcomes for which data were available for the smooth pins versus fixed angle plates comparison, as well as the other outcomes for which data were available for the screws and fixed angle plates, and screws and pins comparisons means we have very little confidence in the estimates of effect for these outcomes. Additional RCTs would increase the certainty of the evidence. We encourage such studies to report outcomes consistent with the core outcome set for hip fracture, including long-term quality of life indicators such as ADL and mobility.

Implementation of an integrated care programme to avoid fragility fractures of the hip in older adults in 18 Bavarian hospitals - study protocol for the cluster-randomised controlled fracture liaison service FLS-CARE. BMC Geriatr 2021; 21:43. [PMID: 33435869 PMCID: PMC7801785 DOI: 10.1186/s12877-020-01966-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 12/16/2020] [Indexed: 11/10/2022] Open
Abstract
Background The economic and public health burden of fragility fractures of the hip in Germany is high. The likelihood of requiring long-term care and the risk of suffering from a secondary fracture increases substantially after sustaining an initial fracture. Neither appropriate confirmatory diagnostics of the suspected underlying osteoporosis nor therapy, which are well-recognised approaches to reduce the burden of fragility fractures, are routinely initiated in the German healthcare system. Therefore, the aim of the study FLS-CARE is to evaluate whether a coordinated care programme can close the prevention gap for patients suffering from a fragility hip fracture through the implementation of systematic diagnostics, a falls prevention programme and guideline-adherent interventions based on the Fracture Liaison Services model. Methods The study is set up as a non-blinded, cluster-randomised, controlled trial with unequal cluster sizes. Allocation to intervention group (FLS-CARE) and control group (usual care) follows an allocation ratio of 1:1 using trauma centres as the unit of allocation. Sample size calculations resulted in a total of 1216 patients (608 patients per group distributed over 9 clusters) needed for the analysis. After informed consent, all participants are assessed directly at discharge, after 3 months, 12 months and 24 months. The primary outcome measure of the study is the secondary fracture rate 24 months after initial hip fracture. Secondary outcomes include differences in the number of falls, mortality, quality-adjusted life years, activities of daily living and mobility. Discussion This study is the first to assess the effectiveness and cost-effectiveness/utility of FLS implementation in Germany. Findings of the process evaluation will also shed light on potential barriers to the implementation of FLS in the context of the German healthcare system. Challenges for the study include the successful integration of the outpatient sector as well as the future course of the coronavirus pandemic in 2020 and its influence on the intervention.

Geriatr Orthop Surg Rehabil 2020; 11:2151459320960087. [PMID: 33117596 PMCID: PMC7573749 DOI: 10.1177/2151459320960087] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 07/30/2020] [Accepted: 08/27/2020] [Indexed: 11/17/2022] Open
Abstract
Introduction Femoral neck fractures in the elderly are increasingly common as a result of a growing geriatric population with 1-year mortality rates approaching 35%. While preoperative medical optimization and early time to surgery have reduced morbidity and mortality, patients with numerous medical comorbidities remain high risk for death in the perioperative period. Identifying those with greatest risk with a scoring system or nomogram may assist multidisciplinary teams in reducing mortality following hemiarthroplasty. Purpose Identify predictors of 30-day mortality in elderly patients who underwent hemiarthroplasty for a femoral neck fracture to generate a predictive nomogram to determine the probability of post-operative mortality. Methods Retrospective evaluation using data from the ACS-NSQIP database from 2005 to 2014 with CPT code 27125 for hip hemiarthroplasty. Multiple factors including demographics and comorbidities were compared in patients who experienced 30-day mortality and those who did not. T-test and chi-square tests were used to analyze data and a multivariate model was generated using logistic regression. Results Advanced age (odds ratio (OR) 1.04), underweight BMI (OR 1.55), male sex (OR 1.80), reduced functional status (OR 2.04), heart failure within 30 days prior to surgery (OR 2.22), American Society of Anesthesiologists grade > 2 (OR > 2.50), disseminated cancer (OR 3.43) were all found to have statistically significant odds ratios for 30-day mortality following hemiarthroplasty. Conclusion A tool based on easily identifiable risk factors, demographics, and comorbidities was developed that can help predict elderly patients who will experience mortality within 30 days of following hemiarthroplasty. In addition to identifying high risk patients, the nomogram can serve as a counseling tool for physicians to use with patients and their families to assist with better understanding of perioperative mortality risk.

Abstract
OBJECTIVES To determine if the Radiographic Union Score for Hip (RUSH) measured at 3 and 6 months after femoral neck fracture were predictive of reoperation for infection, nonunion, delayed union, avascular necrosis, or implant failure within 24 months of initial surgery. DESIGN Secondary analysis of a randomized controlled trial. Logistic regression was performed to investigate associations between lower RUSH and reoperation. Results were reported as odds ratios (OR), 95% confidence intervals (CIs), and associated P values. All tests were 2 tailed with alpha = 0.05. SETTING Eighty-one clinical sites across 8 countries. PATIENTS/PARTICIPANTS Data from 734 of the clinical trial participants with radiographs at 3 and 6 months after fracture fixation were included. INTERVENTION A reviewer blinded to patients' outcomes independently assigned a RUSH at each follow-up time point. MAIN OUTCOME MEASURES Revision surgery rate related to intervention. RESULTS Lower RUSH at 3 and 6 months were associated with increased odds of reoperation within 24 months of fracture fixation. For every 2-point decrease in RUSH at 3 months, there was a 16% increase in the odds of a patient experiencing a re-operation (OR, 1.16; 95% CI, 1.10-1.22; P < 0.0001). A similar association was observed at the 6-month assessment for every 2-point decrease (OR = 1.05; 95% CI, 1.01-1.09; P = 0.005). CONCLUSIONS Decreased radiographic healing as early as 3 months post fracture fixation is associated with developing patient important femoral neck fracture reoperations. This relationship may guide early treatment decisions, suggesting that 3- and 6-month RUSH are a useful surrogate measure of reoperations within 24 months of fracture fixation.

Abstract
PURPOSE In line with several designs for osteosynthesis of femoral neck fracture (FNF), their effectiveness is still estimated by the results of biomechanical and clinical trials, finite element method (FE). But surgeons require the criteria which would define their properties in advance and allow improve the results of treatment. METHODS When new implant (NI) is being designed, we developed such criterion - index efficiency of an implant (IEI) - and performed mathematical comparative researches of properties of NI with the known designs. We analyzed the results of comparative clinical trials on treatment of FNF with various implants considering their IEI. RESULTS Analysis showed that results of comparative clinical trials with the use of various implants for osteosynthesis FNF completely correlated to their IEI; IEI of the NI two to three times exceeds IEI of all known designs, and the destruction percentage of a bone tissue is two to three times less when it is applied. CONCLUSION The offered IEI can be used for designing new implants and allows improving the results of treatment of patients with FNF by optimizing the choice of implant for osteosynthesis.

Abstract
BACKGROUND Neck of Femur (NOF) fractures are a common injury in comorbid elderly patients which are associated with increased rates of morbidity and mortality following fracture. Because of their injury, patients can experience reductions in quality of life and independent living leading to transfer to nursing home or dependent levels of care. Numerous factors are associated with either complications or reductions in survival following fractured NOF. From the VISION cohort there is evidence that troponin elevation in the post-operative period following a diverse range of non-cardiac surgical procedures may lead to an increased risk of mortality in the absence of classical ischaemic or cardiac symptoms. The aim of this systematic review and meta-analysis is to validate the utility of perioperative troponin elevation as a prognostic indicator for mortality and cardiac morbidity in those with fractured NOF. METHODS The PRISMA guidelines for the conduct of meta-analyses were followed. An electronic search was conducted of the EMBASE, MEDLINE (Ovid) and Biosis databases. Studies were included for analysis if they stratified outcomes by perioperative troponin elevation in surgically managed fractured NOF and reported sufficient data on troponin elevation and mortality following surgery. Primary and secondary outcomes assessed were all-cause post-operative mortality and a composite measure of cardiac complications (myocardial infarction, cardiac failure and arrhythmia) respectively. RESULTS Eleven studies met inclusion criteria giving a total of 1363 patients. Overall, 497 patients (36.5%) experienced an elevation in troponin levels following surgery. Perioperative troponin elevation was significantly associated with all-cause mortality (OR 2.6; 95% CI 1.5 - 4.6; p <0.001) and cardiac complications (OR 7.4; 95% CI 3.5 - 15.8; p <0.001). Patient factors significantly associated with troponin elevation included pre-existing coronary artery disease, cardiac failure, hypertension, previous stroke and previous myocardial infarction. CONCLUSION Perioperative troponin elevation is significantly associated with increased mortality and post-operative cardiac complications following fractured NOF and may be a useful prognostic indicator in these patients. Future research should further stratify patients by the magnitude of troponin elevation and further refine the risk factors.

Abstract
INTRODUCTION Total hip arthroplasty (THA) is often used for displaced femoral neck fracture. In this study, institutional hip arthroplasty data were compared with the National American College of Surgeons National Surgical Quality Improvement Program (NSQIP) data for any differences in outcomes between our hospital, with an integrated hip fracture care pathway, and those of the country as a whole. METHODS Elective THA was compared with arthroplasty performed for acute fracture. Outcomes for both groups included thromboembolic event (VTE), death, and deep prosthetic infection. RESULTS Institutional data revealed no increased rate of infection after THA for fracture compared with elective. National Surgical Quality Improvement Program analysis revealed higher infection rates in fracture arthroplasty. There was an increased VTE rate in fracture performed for arthroplasty compared with elective in both institutional and NSQIP data. CONCLUSIONS When performed at an academic medical center with an integrated care program, THA for fracture can have similar infection rates to elective THA. By contrast, national data showed significantly higher rates of infection and VTE for arthroplasty for fracture compared with elective. The contrast in complication rates may be related to well-functioning comprehensive interdisciplinary pathways. Patient-centered care pathways may be optimal for hip fracture patients.

Abstract
Background Observational studies have found that 75% of healthy adult fracture patients (ages 18-50) have serum 25-hydroxyvitamin D (25(OH)D) levels < 30 ng/mL. Although lower serum 25(OH)D levels have yet to be correlated to fracture healing complications or poor fracture outcomes, many orthopedic surgeons are routinely prescribing vitamin D supplements to improve fracture healing in healthy non-osteoporotic patients. To address this gap in the literature, we propose a phase II exploratory randomized controlled trial comparing three vitamin D3 dosing regimens for early surrogate treatment response. Methods We will conduct a 4-arm blinded exploratory phase II trial in 96 adults aged 18-50 years with a closed or low-grade open (Gustilo type I or II) tibial or femoral shaft fracture. Eligible patients will be randomized in equal allocation ratio of 1:1:1:1 to one of the treatment groups: (1) 150,000 IU loading dose vitamin D3 plus daily dose placebo; (2) loading dose placebo plus 4000 IU vitamin D3 per day, (3) loading dose placebo plus 600 IU vitamin D3 per day, or (4) loading dose placebo plus daily dose placebo. The primary outcome is fracture healing, assessed as follows: (1) clinical fracture healing measured using the Function IndeX for Trauma, (2) radiographic fracture healing measured using the Radiographic Union Score for Tibial fractures, and (3) biological fracture healing measured using serum levels of cross-linked C-terminal telopeptides of type I collagen and amino-terminal procollagen propeptides of collagen type I. The main secondary outcome will be assessed by measuring serum 25(OH)D levels. All outcome analyses will be exploratory and adhere to the intention-to-treat principle. Per-protocol sensitivity analyses will also be conducted. Discussion Study results will be disseminated through a publication in an academic journal and presentations at orthopedic conferences. Study results will inform dose selection for a large definitive randomized controlled trial and provide preliminary clinical data on which dose may improve acute fracture healing outcomes in healthy adult patients (18-50 years) at 3 months. Trial registration Vita-Shock (A Blinded Exploratory Randomized Controlled Trial to Determine Optimal Vitamin D3 Supplementation Strategies for Acute Fracture Healing) was registered at ClinicalTrials.gov (identifier NCT02786498) prior to enrollment of participants.

Abstract
BACKGROUND Internal fixation is currently the standard of care for Garden-I and II femoral neck fractures in elderly patients. However, there may be a degree of posterior tilt (measured on preoperative lateral radiograph) above which failure is likely, and primary arthroplasty would be preferred. The purpose of this analysis was to determine the association between posterior tilt and the risk of subsequent arthroplasty following internal fixation of Garden-I and II femoral neck fractures in elderly patients. METHODS This study is a preplanned secondary analysis of data collected in the FAITH (Fixation using Alternative Implants for the Treatment of Hip fractures) trial, an international, multicenter, randomized controlled trial comparing the sliding hip screw with cannulated screws in the treatment of femoral neck fractures in patients ≥50 years old. For each patient who sustained a Garden-I or II femoral neck fracture and had an adequate preoperative lateral radiograph, the amount of posterior tilt was categorized as <20° or ≥20°. Multivariable Cox proportional hazards analysis was used to assess the association between posterior tilt and subsequent arthroplasty during the 2-year follow-up period, controlling for potential confounders. RESULTS Of the 555 patients in the study sample, 67 (12.1%) had posterior tilt ≥20° and 488 (87.9%) had posterior tilt <20°. Overall, 73 (13.2%) of 555 patients underwent subsequent arthroplasty in the 24-month follow-up period. In the multivariable analysis, patients with posterior tilt ≥20° had a significantly higher risk of subsequent arthroplasty compared with those with posterior tilt <20° (22.4% [15 of 67] compared with 11.9% [58 of 488]; hazard ratio, 2.22; 95% confidence interval, 1.24 to 4.00; p = 0.008). The other factor associated with subsequent arthroplasty was age ≥80 years (p = 0.03). CONCLUSIONS In this analysis of patients with Garden-I and II femoral neck fractures, posterior tilt ≥20° was associated with a significantly increased risk of subsequent arthroplasty. Primary arthroplasty may be considered for Garden-I and II femoral neck fractures with posterior tilt ≥20°, especially among older patients. LEVEL OF EVIDENCE Prognostic Level IV.

Abstract
OBJECTIVES To determine stability of 2-part intertrochanteric femur fractures and to determine whether secondary collapse is related to fixation method. DESIGN A retrospective cohort series. SETTING Single Level I Trauma Center. PATIENTS One hundred fourteen patients (82 female) older than 50 years (average age 75 years, range 50-100 years) with an acute low-energy standard obliquity 2-part intertrochanteric femur fracture (OTA/AO 31A) identified from an orthopaedic trauma database were studied. INTERVENTION Twenty-three patients were treated with a sliding hip screw (dynamic hip screw [DHS]), 53 with a dual screw trochanteric entry nail (INTERTAN), and 38 with a single-blade or screw trochanteric entry intramedullary nail (trochanteric fixation nail [TFN]) based on surgeon choice by 4 fellowship-trained orthopaedic trauma surgeons. MAIN OUTCOME MEASURES Fracture collapse was measured by comparing immediate postoperative radiographs to those at final follow-up while controlling for magnification and rotation. RESULTS Collapse averaged 6.8 mm in the DHS group, 3.7 mm in the INTERTAN group, and 7.3 mm in the TFN group. When comparing groups, there was significantly more collapse in the DHS group compared with the INTERTAN group (P = 0.021), and significantly more collapse in the TFN group compared with the INTERTAN group (P < 0.001). Six patients (26%) in the DHS group had >10-mm collapse including 4 (17%) with greater than 20-mm collapse (max = 34.2 mm). Four patients (8%) in the INTERTAN group had >10-mm collapse and none had greater than 12.9 mm. Ten patients (26%) in the TFN group had >10-mm collapse and 3 (5%) had greater than 20-mm collapse (max = 30.7 mm). CONCLUSION Stability of 2-part intertrochanteric femur fractures is dependent on the fixation device. These fractures are not necessarily stable when treated with a sliding hip screw as 26% treated with this method collapsed greater than 10 mm and 17% more than 20 mm. Dual screw intramedullary nail fixation seems to be most effective to maintain stability for patients with this fracture pattern. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
OBJECTIVES The FAITH trial evaluated effects of sliding hip screws versus cancellous screws in femoral neck fracture patients. Using FAITH trial data, we quantified changes in living status, use of aids, and investigated factors associated with living and walking independently 12 months after fracture. METHODS We conducted a descriptive analysis to quantify patients' changes in living status, use of aids, and used multivariable Cox regression analyses to determine factors associated with living and walking independently after fracture. RESULTS Of patients who lived independently before hip fracture, 3.07% (50-80 years old) and 19.81% (>80 years old) were institutionalized 12 months after injury. Of patients who were walking independently before injury, 33.62% (50-80 years old) and 69.34% (>80 years old) required a walking aid 12 months after injury. Factors associated with higher chances of living independently included the following: being between 50 and 80 years, having a class I American Society of Anesthesiologists classification, not using a walking aid before fracture, being a nonsmoker or former smoker, and having an acceptable quality of implant placement. Factors associated with higher chances of walking without an aid included the following: being between 50 and 80 years, having a class I American Society of Anesthesiologists classification, living independently before fracture, being a nonsmoker or former smoker, having an undisplaced fracture, and not requiring revision surgery. CONCLUSIONS Femoral neck fracture patients suffer great losses of independence. Identifying factors associated with living and walking independently after hip fracture may help surgeons better identify which patients are at risk and optimize care of patients with this injury.

Abstract
BACKGROUND Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. METHODS We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. RESULTS Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (for every 5-point increase) (HR 1.19, 95% CI 1.02-1.39; P = 0.027), displaced fracture (HR 2.16, 95% CI 1.44-3.23; P < 0.001), unacceptable quality of implant placement (HR 2.70, 95% CI 1.59-4.55; P < 0.001), and smokers treated with cancellous screws versus smokers treated with a sliding hip screw (HR 2.94, 95% CI 1.35-6.25; P = 0.006). Additionally, for every 10-year decrease in age, participants experienced an average increased risk of 39% for hardware removal. CONCLUSIONS Results of this study may inform future research by identifying high-risk patients who may be better treated with arthroplasty and may benefit from adjuncts to care (HR 1.39, 95% CI 1.05-1.85; P = 0.020).

Abstract
BACKGROUND The design and application of assisted instrumentation for internal fixation of femoral neck fractures with multiple screws are still evolving. A novel guide based on a femoral neck section was designed to improve the accuracy of screw placement, and its efficacy was evaluated. METHODS A guide based on a femoral neck section was designed for assisted fixation of femoral neck fractures with multiple screws. Femoral specimens from 10 adults (20 femurs) underwent assisted internal fixation for a femoral neck fracture with 3 cannulated screws using the new guide technique or conventional technique. The accuracy of screw orientation and entry point, the accuracy of optimal screw positioning, and drilling attempts, operative time, and fluoroscopy time were recorded. RESULTS Among all 20 specimens, 60 screws were inserted successfully. Screw parallelism, operative time, and fluoroscopy time showed no statistical difference between the new guide technique and conventional technique (P > 0.05). The accuracy of optimal screw positioning was determined by the contained screw area ratio, distance between screws, distance from the centre of the femoral neck section, distance between screws and the femoral neck cortex, and Drilling attempts were statistical significantly better (data in the first three were larger and in the latter two was smaller) with the new guide technique, than with conventional technique (P < 0.05). CONCLUSIONS This new, two-dimensional, fluoroscopy-assisted, percutaneous guide technique enables accurate and optimal screw positioning in internal fixation of femoral neck fractures, compared with conventional technique.

Abstract
Aims The primary aim of this prognostic study was to identify baseline factors associated with physical health-related quality of life (HRQL) in patients after a femoral neck fracture. The secondary aims were to identify baseline factors associated with mental HRQL, hip function, and health utility. Patients and Methods Patients who were enrolled in the Fixation using Alternative Implants for the Treatment of Hip Fractures (FAITH) trial completed the 12-item Short Form Health Survey (SF-12), Western Ontario and McMaster Universities Arthritis Index, and EuroQol 5-Dimension at regular intervals for 24 months. We conducted multilevel mixed models to identify factors potentially associated with HRQL. Results The following were associated with lower physical HRQL: older age (-1.42 for every ten-year increase, 95% confidence interval (CI) -2.17 to -0.67, p < 0.001); female gender (-1.52, 95% CI -3.00 to -0.05, p = 0.04); higher body mass index (-0.69 for every five-point increase, 95% CI -1.36 to -0.02, p = 0.04); American Society of Anesthesiologists class III ( versus class I) (-3.19, 95% CI -5.73 to -0.66, p = 0.01); and sustaining a displaced fracture (-2.18, 95% CI -3.88 to -0.49, p = 0.01). Additional factors were associated with mental HRQL, hip function, and health utility. Conclusion We identified several baseline factors associated with lower HRQL, hip function, and utility after a femoral neck fracture. These findings may be used by clinicians to inform treatment and outcomes. Cite this article: Bone Joint J 2018;100-B:361-9.

Abstract
Daily administration of vitamin D is important for maintaining bone homeostasis. The orthopedic community has shown increased interest in vitamin D supplementation and patient outcomes after fracture. The current study used data from a large hip fracture trial to determine the proportion of patients who consistently used vitamin D after hip fracture surgery and to determine whether supplementation was associated with improved health-related quality of life and reduced reoperation rates. The FAITH study is a multicenter trial of elderly patients with femoral neck fracture treated with internal fixation. The current study asked a subset of patients included in the FAITH study about vitamin D supplementation and categorized them as consistent users, inconsistent users, or nonusers. This study also evaluated whether supplementation was associated with improved quality of life and reduced reoperation rates. The final analysis included 573 patients (mean age, 74.1 years; female, 66.3%; nondis-placed fractures, 72.4%). A total of 18.7% of participants reported no use of vitamin D, 35.6% reported inconsistent use, and 45.7% reported consistent use. Adjusted analysis found that consistent supplementation was associated with a 2.42 increase of the Short Form-12 physical component score 12 months postoperatively (P=.033). However, supplementation was not associated with reduced reoperation rates (P=.386). Despite guidelines recommending vitamin D supplementation, a low proportion of elderly patients with hip fracture use vitamin D consistently, suggesting a need for additional strategies to promote compliance. This study found that the use of vitamin D was associated with a statistically significant but not clinically significant improvement in health-related quality of life after hip fracture. Further research is needed to confirm these findings. [Orthopedics. 2017; 40(5):e868-e875.].

Abstract
BACKGROUND Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. METHODS For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries. Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws. Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups. The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function. Analyses followed the intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT00761813. FINDINGS Between March 3, 2008, and March 31, 2014, we randomly assigned 1108 patients to receive a sliding hip screw (n=557) or cancellous screws (n=551). Reoperations within 24 months did not differ by type of surgical fixation in those included in the primary analysis: 107 (20%) of 542 patients in the sliding hip screw group versus 117 (22%) of 537 patients in the cancellous screws group (hazard ratio [HR] 0·83, 95% CI 0·63-1·09; p=0·18). Avascular necrosis was more common in the sliding hip screw group than in the cancellous screws group (50 patients [9%] vs 28 patients [5%]; HR 1·91, 1·06-3·44; p=0·0319). However, no significant difference was found between the number of medically related adverse events between groups (p=0·82; appendix); these events included pulmonary embolism (two patients [<1%] vs four [1%] patients; p=0·41) and sepsis (seven [1%] vs six [1%]; p=0·79). INTERPRETATION In terms of reoperation rates the sliding hip screw shows no advantage, but some groups of patients (smokers and those with displaced or base of neck fractures) might do better with a sliding hip screw than with cancellous screws.

Abstract
The treatment of high-energy open tibia fractures is challenging in both the military and civilian environments. Treatment with modern ring external fixation may reduce complications common in these patients. However, no study has rigorously compared outcomes of modern ring external fixation with commonly used internal fixation approaches. The FIXIT study is a prospective, multicenter randomized trial comparing 1-year outcomes after treatment of severe open tibial shaft fractures with modern external ring fixation versus internal fixation among men and women of ages 18-64. The primary outcome is rehospitalization for major limb complications. Secondary outcomes include infection, fracture healing, limb function, and patient-reported outcomes including physical function and pain. One-year treatment costs and patient satisfaction will be compared between the 2 groups, and the percentage of Gustilo IIIB fractures that can be salvaged without soft tissue flap among patients receiving external fixation will be estimated.

Abstract
INTRODUCTION Current literature suggests that total hip replacement (THR) is superior to hemiarthroplasty (HA) for neck of femur fracture in selected group of patients. The outcomes of THR undertaken for trauma setting remain unclear when comparing with elective THR. We compared the outcomes of THR trauma cohort with best-matched elective cohort. METHODS We retrospectively reviewed 102 patients that underwent THR due to trauma from 2011 to 2013. We had access to 90 cases with complete records. Another 90 matched elective cases were obtained from local arthroplasty database. The elective cases were matched for gender, surgical approaches, surgeon's grade, types of implant, patient's age at operation date of ±5 years and operation date of ±60days. Subsequently, the selection criteria were relaxed to patient's age at operation date of ±10 years and operation date of ±60days. Unmatched cases were excluded. Complications and death rate were compared. RESULTS The average age for both cohorts was 70 years. The trauma cohort had statistically significant lower BMI and longer hospital stay (p=0.001). The Functional Comorbidity Index (FCI) and Charlson Age Comorbidity Index (CACI) were the same for both cohorts, reflecting an active patient selection for THR in our centre. The trauma cohort had higher surgical complication rate (9% vs 4%), particularly higher dislocation rate (7% vs 1%); and higher medical complication rate (32% vs 6%). These were consistent with the literature. Contrary to literature, the trauma cohort had six dislocations that five of them were done via anterolateral approach. Among the eight trauma cases with surgical complications, six cases were performed by trainees. The cause of surgical complications remains unclear due to the nature of retrospective study. The trauma cohort had higher death rate than the elective cohort (14% vs 4%), with one post-operative cardiac arrest in the trauma cohort. The rest were non-orthopaedic related deaths, ranging between four months to four years. CONCLUSION A more robust way of selecting trauma patients for THR is warranted to reduce morbidity and mortality. Follow-up for the trauma cohort is warranted, as the patients are likely to outlive the implants.

Abstract
BACKGROUND The Radiographic Union Score for Hip (RUSH) is a previously validated outcome instrument designed to improve intra- and interobserver reliability when describing the radiographic healing of femoral neck fractures. The ability to identify fractures that have not healed is important for defining nonunion in clinical trials and predicting patients who will likely require additional surgery to promote fracture healing. We sought to investigate the utility of the RUSH score to define femoral neck fracture nonunion. QUESTIONS/PURPOSES (1) What RUSH score threshold yields at least 98% specificity to diagnose nonunion at 6 months postinjury? (2) Using the threshold identified, are patients below this threshold at greater risk of reoperation for nonunion and for other indications? METHODS A representative sample of 250 out of a cohort of 725 patients with adequate 6-month hip radiographs was analyzed from a multinational elderly hip fracture trial (FAITH). All patients had a femoral neck fracture and were treated with either multiple cancellous screws or a sliding hip screw. Two reviewers independently determined the RUSH score based on the 6-month postinjury radiographs and interrater reliability was assessed with the interclass correlation coefficient (ICC). There was substantial reliability between the reviewers assigning the RUSH scores (ICC, 0.81; 95% confidence interval [CI], 0.76-0.85). The RUSH score is a checklist-based system that quantifies four measures of healing: cortical bridging, cortical fracture disappearance, trabecular consolidation, and trabecular fracture disappearance.. Fracture healing was determined by two independent methods: (1) concurrently by the treating surgeon using both clinical and radiographic assessments as per routine clinical care; and (2) retrospectively by a Central Adjudication Committee using complete obliteration of the fracture line on radiographs alone. Receiver operating characteristic tables were used to define a RUSH threshold score that was > 98% specific for fracture nonunion. RESULTS A threshold score of < 18 was associated with a 100% specificity (95% CI, 97%-100%) and a positive predictive value of 100% (95% CI, 73%-100%) for radiographic nonunion. In contrast, using the fracture healing assessments of the treating surgeons failed to identify a useful discriminatory nonunion threshold and the highest positive predictive value was 43%. With respect to complications, patients with RUSH scores below 18 had greater risk of undergoing reoperation for nonunion (reoperation when < 18: six of 13 [46%]; reoperation when ≥ 18: 11 of 237 [54%]; relative risk [RR], 9.9 [95% CI, 4.4-22.7]; p < 0.001) and for all indications (reoperation when < 18: eight of 13 [62%]; reoperation when ≥ 18: 54 of 237 [38%]; RR, 2.7 [95% CI, 1.7-4.4]; p = 0.004). CONCLUSIONS The 6-month RUSH score is a reliable method for assessing radiographic healing. Our results highlight the discordance between radiographic determinations and clinician assessments of fracture healing and stress the need for clinical data to be incorporated in research studies evaluating fracture healing.

Does Teriparatide Improve Femoral Neck Fracture Healing: Results From A Randomized Placebo-controlled Trial. Clin Orthop Relat Res 2016; 474:1234-44. [PMID: 26932738 PMCID: PMC4814417 DOI: 10.1007/s11999-015-4669-z] [Citation(s) in RCA: 56] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2015] [Accepted: 12/02/2015] [Indexed: 01/31/2023]
Abstract
BACKGROUND There is a medical need for therapies that improve hip fracture healing. Teriparatide (Forteo(®)/ Forsteo(®), recombinant human parathyroid hormone) is a bone anabolic drug that is approved for treatment of osteoporosis and glucocorticoid-induced osteoporosis in men and postmenopausal women at high fracture risk. Preclinical and preliminary clinical data also suggest that teriparatide may enhance bone healing. QUESTIONS/PURPOSES We wished to test the hypotheses that treatment with teriparatide versus placebo would improve femoral neck fracture healing after internal fixation as measured by (1) frequency of revision surgery, (2) radiographic fracture healing, and (3) other outcomes including pain control, gait speed, and safety. METHODS We initiated two separate, but identically designed, clinical trials to meet FDA requirements to provide substantial evidence to support approval of a new indication. The two prospective, randomized double-blind, placebo-controlled Phase III studies were designed to evaluate the effect of subcutaneous teriparatide (20 μg/day) for 6 months versus placebo on fracture healing at 24 months. The trials were conducted concurrently with a planned enrollment of 1220 patients per trial. However, enrollment was stopped owing to very slow patient accrual, and an a priori decision was made to pool the results of those studies for statistical analyses before study completion; pooling was specified in both protocols. Randomization was stratified by fixation (sliding hip screw or multiple cancellous screws) and fracture type (displaced or nondisplaced). An independent Central Adjudication Committee reviewed revision surgical procedures and radiographs. A total of 159 patients were randomized in the two trials (81 placebo, 78 teriparatide). The combined program had very low power to detect the originally expected treatment effect but had approximately 80% power to detect a larger difference of 12% between treatment groups for risk of revision surgery. RESULTS The proportion of patients undergoing revision surgery at 12 months was 14% (11 of 81) in the placebo group versus 17% (13 of 78) in the teriparatide group. Central Adjudication Committee review excluded two of these patients treated with placebo from the primary analysis. After exclusions, the proportion of patients who did not undergo revision surgery at 12 months (primary endpoint) was not different between the study and placebo groups, at 88% in the placebo group (90% CI, 0.79-0.93) versus 84% in the teriparatide group (90% CI, 0.75-0.90; p = 0.743). There also were no differences between groups in the proportion of patients achieving radiographic fracture healing at 12 months (75% [61 of 81] placebo versus 73% [57 of 78] teriparatide; odds ratio, 0.89; 90% CI, 0.46-1.72; p = 0.692) or in measures of pain control (such as pain during ambulation, 92% [55 of 62] placebo versus 91% [52 of 57] teriparatide; odds ratio, 0.91; 90% CI, 0.25-3.37; p = 0.681). The frequency of patients reporting adverse events was 49% [40 of 81] in the placebo group versus 45% [35 of 78] in the teriparatide group (p = 0.634) during the 6-month treatment period. CONCLUSIONS The small sample size limited this study's power to detect potential differences, and the results are exploratory. With the patients available, teriparatide did not decrease the risk of revision surgery, improve radiographic signs of fracture healing, or decrease pain compared with the placebo. The adverse event data observed were consistent with the teriparatide safety profile. Functional and health outcome data from the studies may help improve our understanding of patients recovering from femoral neck fractures. Further large controlled studies are required to determine the effect of teriparatide on fracture healing. LEVEL OF EVIDENCE Level II, prospective study.

Abstract
Assessment of fracture union is a critical concept in clinical orthopaedics; however, there is no established "gold standard" for fracture healing. This review provides an overview of the problems related to the assessment of fracture healing, examines currently available tools to determine union, discusses the role of functional outcomes in the assessment of fracture healing, and finally evaluates healing outcome measures as they pertain to fracture trials. Because there is no universally accepted method to determine fracture healing, orthopaedic surgeons must rely on a range of tools that can include: radiographic assessment, mechanical assessment, serologic markers, and clinical evaluation (including functional outcomes). When used in conjunction, these tools can help to improve the sensitivity and specificity of determining fracture union. This is furthermore relevant when conducting fracture healing trials, for which there is little consensus between surgeons or the Food and Drug Administration as to optimal study endpoints. Such studies should therefore include a composite outcome measure consisting of radiographic and functional assessments to increase the quality and consistency of fracture healing trials.

Abstract
Femoral neck fractures are a commonly encountered injury in orthopaedic practice and result in significant morbidity and mortality. It is essential that surgeons are able to recognize specific fracture patterns and patient characteristics that indicate the use of particular implants and methods to effectively manage these injuries. Use of the Garden and Pauwels classification systems has remained the practical mainstay of femoral neck fracture characterization that help dictate appropriate treatment. Operative options include in situ fixation, closed or open reduction and internal fixation, hemiarthroplasty, and total hip arthroplasty. Recent reports demonstrate diversity among orthopaedic surgeons in regard to the optimal treatment of femoral neck fractures and changing trends in management. The present discussion focuses on the current indications and methods for femoral neck fracture management to provide direction with respect to appropriate and effective care of these injuries.

Abstract
BACKGROUND Numerous different implants with screws, pins and side plates have been used for the internal fixation of intracapsular hip fractures. OBJECTIVES To determine from randomised trials which implant is superior for the internal fixation of intracapsular proximal femoral fractures. SEARCH STRATEGY We searched the Cochrane Musculoskeletal Injuries Group specialised register. The date of the most recent search was December 2000. SELECTION CRITERIA Randomised and quasi-randomised trials comparing different implants for the internal fixation of intracapsular hip fractures in adults. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality, by use of a ten item scale, and extracted data. Additional information was sought from trialists. After grouping by implant type, comparable groups of trials were subgrouped and where appropriate, data were pooled using the fixed effects model. MAIN RESULTS Twenty-seven studies involving 5269 participants (5274 fractures) were included in the study. Considerable variation in the quality of methodology between studies was found and biases due to familiarity with some of the implants were noted. None of the implants tested were found to be significantly superior for any of the outcome measures related to fracture healing complications or mortality. The sliding hip screw was found to take longer to insert and to have an increased operative blood loss compared with multiple screws or pins. REVIEWER'S CONCLUSIONS No clear conclusions can be made on the choice of implant for internal fixation of intracapsular fractures from the available evidence within randomised trials.
