Abstract
BACKGROUND The German Arthroplasty Registry (EPRD) recorded nearly 52,000 femoral neck fractures treated with arthroplasty by 2020. This study aimed to identify survival rates and risk factors for hip prosthesis failure. MATERIAL AND METHODS The study included all patients with arthroplasty after hip fractures documented in the EPRD. Data were analyzed with focus on failure rate regarding implant, implantation technique, age, BMI, and comorbidities. For more complex analysis of dependencies, the machine learning algorithm (MLA) XGBoost (Extreme Gradient Boosting) was used. RESULTS The study included 51,938 patients. The failure rate was 3.7% for HEs and 5.6% for THA. The failure rate increased in male patients (p < 0.0001), those with higher BMI, young patients with a high Elixhauser Comorbidity Score (ECS) and a cementless technique. The timepoint of surgery, i.e. ,working day vs. weekend or holiday had no influence on the outcome. The feature importance (FI) generated by MLA demonstrated factors with the highest impact on failure, i.e., survival time (1029), BMI (722), and age (481). CONCLUSION For younger patients with comorbidities, a cemented implantation technique should be considered. Failure rates of arthroplasties did not differ on workdays compared to weekends or holidays. MLA are suitable to analyze registry data for complex correlations of factors.

Machine Learning Did Not Outperform Conventional Competing Risk Modeling to Predict Revision Arthroplasty. Clin Orthop Relat Res 2024; 482:1472-1482. [PMID: 38470976 PMCID: PMC11272341 DOI: 10.1097/corr.0000000000003018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 02/01/2024] [Indexed: 03/14/2024]
Abstract
BACKGROUND Estimating the risk of revision after arthroplasty could inform patient and surgeon decision-making. However, there is a lack of well-performing prediction models assisting in this task, which may be due to current conventional modeling approaches such as traditional survivorship estimators (such as Kaplan-Meier) or competing risk estimators. Recent advances in machine learning survival analysis might improve decision support tools in this setting. Therefore, this study aimed to assess the performance of machine learning compared with that of conventional modeling to predict revision after arthroplasty. QUESTION/PURPOSE Does machine learning perform better than traditional regression models for estimating the risk of revision for patients undergoing hip or knee arthroplasty? METHODS Eleven datasets from published studies from the Dutch Arthroplasty Register reporting on factors associated with revision or survival after partial or total knee and hip arthroplasty between 2018 and 2022 were included in our study. The 11 datasets were observational registry studies, with a sample size ranging from 3038 to 218,214 procedures. We developed a set of time-to-event models for each dataset, leading to 11 comparisons. A set of predictors (factors associated with revision surgery) was identified based on the variables that were selected in the included studies. We assessed the predictive performance of two state-of-the-art statistical time-to-event models for 1-, 2-, and 3-year follow-up: a Fine and Gray model (which models the cumulative incidence of revision) and a cause-specific Cox model (which models the hazard of revision). These were compared with a machine-learning approach (a random survival forest model, which is a decision tree-based machine-learning algorithm for time-to-event analysis). Performance was assessed according to discriminative ability (time-dependent area under the receiver operating curve), calibration (slope and intercept), and overall prediction error (scaled Brier score). Discrimination, known as the area under the receiver operating characteristic curve, measures the model's ability to distinguish patients who achieved the outcomes from those who did not and ranges from 0.5 to 1.0, with 1.0 indicating the highest discrimination score and 0.50 the lowest. Calibration plots the predicted versus the observed probabilities; a perfect plot has an intercept of 0 and a slope of 1. The Brier score calculates a composite of discrimination and calibration, with 0 indicating perfect prediction and 1 the poorest. A scaled version of the Brier score, 1 - (model Brier score/null model Brier score), can be interpreted as the amount of overall prediction error. RESULTS Using machine learning survivorship analysis, we found no differences between the competing risks estimator and traditional regression models for patients undergoing arthroplasty in terms of discriminative ability (patients who received a revision compared with those who did not). We found no consistent differences between the validated performance (time-dependent area under the receiver operating characteristic curve) of different modeling approaches because these values ranged between -0.04 and 0.03 across the 11 datasets (the time-dependent area under the receiver operating characteristic curve of the models across 11 datasets ranged between 0.52 to 0.68). In addition, the calibration metrics and scaled Brier scores produced comparable estimates, showing no advantage of machine learning over traditional regression models. CONCLUSION Machine learning did not outperform traditional regression models. CLINICAL RELEVANCE Neither machine learning modeling nor traditional regression methods were sufficiently accurate in order to offer prognostic information when predicting revision arthroplasty. The benefit of these modeling approaches may be limited in this context.

Abstract
Prozessänderungen im perioperativen Setting werden selten analysiert, weil ihre Ergebnisse nicht unmittelbar fassbar sind und es einer hohen Fallzahl bedarf. Primäres Ziel war es, Prozessänderungen retrospektiv anhand proximaler Femurfrakturen (PF) zu evaluieren und deren Effekt mit verschiedenen Zielkriterien zu überprüfen. Sekundäres Ziel war die Definition möglicher Qualitätskriterien für die Versorgung von PF.Retrospektive Analyse der Datenbank eines Level-1-Traumazentrums zu PF. Eingeschlossen wurden alle osteosynthetisch und endoprothetisch versorgten PF im Behandlungszeitraum vom 01.01.2006 bis 31.12.2021. Der Zeitraum von 16 Jahren wurde für die Statistik trichotom aufgeteilt und die ersten 6 Jahre als Ausgangsbasis verwendet. Insgesamt 10 Prozessänderungen wurden in den folgenden 10 Jahren vorgenommen. Die Auswirkungen dieser Änderungen wurden anhand 1. der operativen Revisionsrate, 2. der Infektionsrate, 3. der perioperativen Transfusionsrate sowie 4. der 1-Jahres-Letalität überprüft.Insgesamt 4163 PF wurden analysiert. Hinsichtlich der Zielkriterien zeigten die Änderungen der ersten 5 Jahre (2012-2016; intramedulläres Verfahren für Osteosynthesen sowie Einwegabdeckung und Einwegkittel) den stärksten Effekt mit einer erstmaligen Senkung der operativen Revisionsrate unter 10% auf Dauer. Weitere Prozessoptimierungen der letzten 5 Jahre (2017-2021) erbrachten ebenfalls messbare Verbesserungen (Senkung der Infektions- und Transfusionsrate). Die 1-Jahres-Letalität blieb unverändert, auch während der COVID-19-Pandemie.Prozessänderungen bei PF führen nicht unmittelbar zu objektiv messbaren Verbesserungen. Rückblickend erscheint der Paradigmenwechsel von extra- auf intramedulläre Osteosynthese den höchsten Effekt erzielt zu haben, wenngleich über die letzten 10 Jahre eine schrittweise Besserung aller Zielkriterien eintrat - mit Ausnahme der Letalität. Als objektive Qualitätskontrolle sollte eine 1-Jahres-Revisionsrate unter 10% angestrebt sein.

Abstract
BACKGROUND Practice patterns regarding the use of unipolar hemiarthroplasty, bipolar hemiarthroplasty, and total hip arthroplasty (THA) for femoral neck fractures in older patients vary widely. This is due in part to limited data stipulating the specific circumstances under which each form of arthroplasty provides the most predictable outcome. The purpose of this study was to investigate the patient characteristics for which unipolar hemiarthroplasty, bipolar hemiarthroplasty, or THA might be preferable due to a lower risk of all-cause revision. METHODS A U.S. health-care system's hip fracture registry was used to identify patients ≥60 years old who underwent unipolar hemiarthroplasty, bipolar hemiarthroplasty, or THA for hip fracture from 2009 through 2021. Unipolar and bipolar hemiarthroplasty were compared with THA within patient subgroups defined by age (60 to 79 versus ≥80 years) and American Society of Anesthesiologists (ASA) classification (I or II versus III); patients with an ASA classification of IV or higher were excluded. Multivariable Cox proportional hazard regression analysis was used to evaluate all-cause revision risk while adjusting for confounders, with mortality considered as a competing risk. RESULTS There were 14,277 patients in the final sample (median age, 82 years; 70% female; 80% White; 69% with an ASA classification of III; median follow-up, 2.7 years), and the procedures included 7,587 unipolar hemiarthroplasties, 5,479 bipolar hemiarthroplasties, and 1,211 THAs. In the multivariable analysis of all patients, both unipolar (hazard ratio [HR] = 2.15, 95% confidence interval [CI] = 1.48 to 3.12; p < 0.001) and bipolar (HR = 1.92, 95% CI = 1.31 to 2.80; p < 0.001) hemiarthroplasty had higher revision risks than THA. In the age-stratified multivariable analysis of patients aged 60 to 79 years, both unipolar (HR = 2.17, 95% CI = 1.42 to 3.34; p = 0.004) and bipolar (HR = 1.69, 95% CI = 1.08 to 2.65; p = 0.022) hemiarthroplasty also had higher revision risks than THA. In the ASA-stratified multivariable analysis, patients with an ASA classification of I or II had a higher revision risk after either unipolar (HR = 3.52, 95% CI = 1.87 to 6.64; p < 0.001) or bipolar (HR = 2.31, 95% CI = 1.19 to 4.49; p = 0.013) hemiarthroplasty than after THA. No difference in revision risk between either of the hemiarthroplasties and THA was observed among patients with an age of ≥80 years or those with an ASA classification of III. CONCLUSIONS In this study of hip fractures in older patients, THA was associated with a lower risk of all-cause revision compared with unipolar and bipolar hemiarthroplasty among patients who were 60 to 79 years old and those who had an ASA classification of I or II.

Abstract
PURPOSE Several controversies in the optimal treatment of femoral neck fractures persist, together with large variations in clinical practice. METHODS A narrative literature review covering 4 current controversies in the surgical management of femoral neck fractures (total hip arthroplasty (THA) versus hemiarthroplasty (HA), cemented versus uncemented HA, internal fixation versus arthroplasty, operative versus non-operative) was performed. Available literature was balanced against annual trends in the management of femoral neck fractures from the public domain of several national registries (Sweden, Norway, The Netherlands, Australia and New Zealand). RESULTS For most controversies, the literature provides stronger evidence than is reflected by variations encountered in daily practice. Implementation of clinical evidence tends to lag behind and important differences exist between countries. CONCLUSIONS Trends of clinical practice from national registries indicate that implementation of available clinical evidence needs to be improved.

Abstract
BACKGROUND Hemiarthroplasty (HA) for hip fractures can be performed with a unipolar or bipolar head. We describe the use of unipolar and bipolar HA after a hip fracture in the Netherlands and determined revision rates and risk factors. METHODS All HAs for an acute hip fracture registered in the Dutch Arthroplasty Register (LROI) during 2007 to 2021 were included; 44,127(88%) unipolar and 6,013(12%) bipolar HAs. Competing risk survival analyses were performed with revision for any reason as the endpoint. Multivariable Cox regression analyses were performed adjusting for patient and surgery-related factors. RESULTS The 1-year, 5-year, and 10-year revision rates were comparable for unipolar and bipolar HA. Cox regression analysis showed a hazard ratio of 1.2 (95% confidence interval (CI) 1.0 to 1.4)) after adjustment for confounders for bipolar heads. In cases of a cemented stem, the 1-year cumulative incidence of revision was lower (1.5% (CI 1.4 to 1.7%) compared to uncemented stems (2.4% (CI 2.1 to 2.7%); uncemented stems showed higher risks for revision after adjustment compared to cemented stems (hazard ratio 1.4 (CI 1.2 to 1.5)). The anterior, antero-lateral, and straight-lateral approach showed lower risk for revision compared to the postero-lateral approach. CONCLUSION The revision rate for bipolar HA and unipolar HA was comparable. However, after adjustment for potential confounders the risk for revision showed an estimated 20% increased revision risk for bipolar heads, although not statistically significant. For both head types, the risk for revision was significantly higher when an uncemented stem was chosen or the postero-lateral approach was used.

Abstract
This study aimed to examine the incidence rate of early reoperations following hip fracture surgery and determine the safety of resuming direct oral anticoagulants. Many orthopedic surgeons are reluctant to resume chronic anticoagulation therapy for patients after surgical intervention for hip fractures. One of the main reasons is the potential for reoperation in the case of surgical complications. We conducted a retrospective cohort study at an Academic Level I trauma center, reviewing the records of 425 geriatric patients (age > 60) who underwent hip fracture surgery between 2018 and 2020, including a subgroup treated with direct oral anticoagulants prior to hospitalization. The study assessed the incidence rate of complications requiring early reoperation. Out of the 425 patients, only nine (2%) required reoperation within a month after discharge, with two (0.5%) on chronic anticoagulation therapy. None of the reoperations were urgent, and all were performed at least 24 h after re-admission. The findings revealed a very low incidence rate of reoperations in patients who underwent hip fracture surgery, with no reoperations performed within 24 h of re-admission. Consequently, we believe that resuming chronic direct oral anticoagulants is a safe and effective approach when discharging patients after hip fracture surgery.

Abstract
INTRODUCTION Social determinants of health (SDOH) have previously been shown to impact orthopedic surgery outcomes. This study assessed whether greater socioeconomic disadvantage in patients undergoing hemiarthroplasty following femoral neck fracture was associated with differences in (1) medical complications, (2) emergency department (ED) utilization, (3) readmission rates, and (4) payments for care. METHODS A US nationwide database was queried for hemiarthroplasties performed between 2010 and 2020. Area Deprivation Index (ADI), a validated measure of socioeconomic disadvantage reported on a scale of 0-100, was used to compare two cohorts of greater and lesser deprivation. Patients undergoing hemiarthroplasty from high ADI (95% +) were 1:1 propensity score matched to a comparison group of lower ADI (0-94%) while controlling for age, sex, and Elixhauser Comorbidity Index. This yielded 75,650 patients evenly distributed between the two cohorts. Outcomes studied were 90-day medical complications, ED utilizations, readmissions, and payments for care. Multivariate logistic regression models were utilized to calculate odds ratios (ORs) of the relationship between ADI and outcomes. p Values < 0.05 were significant. RESULTS Patients of high ADI developed greater medical complications (46.74% vs. 44.97%; OR 1.05, p = 0.002), including surgical site infections (1.19% vs. 1.00%; OR 1.20, p = 0.011), cerebrovascular accidents (1.64% vs. 1.41%; OR 1.16, p = 0.012), and respiratory failures (2.27% vs. 2.02%; OR 1.13, p = 0.017) compared to patients from lower ADIs. Although comparable rates of ED visits (2.92% vs. 2.86%; OR 1.02, p = 0.579), patients from higher ADI were readmitted at diminished rates (10.57% vs. 11.06%; OR 0.95, p = 0.027). Payments were significantly higher on the day of surgery ($7,570 vs. $5,974, p < 0.0001), as well as within 90 days after surgery ($12,700 vs. $10,462, p < 0.0001). CONCLUSIONS Socioeconomically disadvantaged patients experience increased 90-day medical complications and payments, similar ED utilizations, and decreased readmissions. These findings can be used to inform healthcare providers to minimize disparities in care. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Hemiarthroplasty is the standard treatment for patients with femoral neck fractures (FNFs). Controversy exists over the use of bone cement in hip fractures treated with hemiarthroplasty. OBJECTIVE We performed an updated systematic review and meta-analysis to compare cemented and uncemented hemiarthroplasty in patients with femoral neck fractures. METHODS A literature review was conducted using Cochrane Library, ScienceDirect, PubMed, Embase, Medline, Web of Science, CNKI, VIP, Wang Fang, and Sino Med databases. Studies comparing cemented with uncemented hemiarthroplasty for FNFs in elderly patients up to June 2022 were included. Data were extracted, meta-analyzed, and pooled as risk ratios (RRs) and weighted mean differences (WMDs) with a 95% confidence interval (95% CI). RESULTS Twenty-four RCTs involving 3471 patients (1749 cement; 1722 uncemented) were analyzed. Patients with cemented intervention had better outcomes regarding hip function, pain, and complications. Significant differences were found in terms of HHS at 6 weeks (WMD 12.5; 95% CI 6.0-17.0; P < 0.001), 3 months (WMD 3.3; 95% CI 1.6-5.0; P < 0.001), 4 months (WMD 7.3; 95% CI 3.4-11.2; P < 0.001), and 6 months (WMD 4.6; 95% CI 3.3-5.8; P < 0.001) postoperatively. Patients with cemented hemiarthroplasty had lower rates of pain (RR 0.59; 95% CI 0.39-0.9; P = 0.013), prosthetic fracture (RR 0.24; 95% CI 0.16-0.38; P < 0.001), subsidence/loosening (RR 0.29; 95% CI 0.11-0.78; P = 0.014), revisions (RR 0.59; 95% CI 0.40-0.89; P = 0.012), and pressure ulcers (RR 0.43; 95% CI 0.23-0.82; P = 0.01) at the expense of longer surgery time (WMD 7.87; 95% CI 5.71-10.02; P < 0.001). CONCLUSION This meta-analysis demonstrated that patients with cemented hemiarthroplasty had better results in hip function and pain relief and lower complication rates at the expense of prolonged surgery time. Cemented hemiarthroplasty is recommended based on our findings.

Abstract
INTRODUCTION Hip arthroplasty is the treatment of choice for displaced femoral neck fractures among the older population. The hip prosthesis dislocation is one of the most pointed potential complications after hip arthroplasty, but there is a lack of updated information on the effect of dislocation on the survival of older hip fracture patients so treated by hip hemiarthroplasty. We aim to evaluate the standalone effect of hip prosthesis dislocation after hip fracture hemiarthroplasty on patients' survival outcomes. MATERIALS AND METHODS We conducted a retrospective multicenter study, including 6631 femoral neck fracture patients over 65 surgically treated by hemiarthroplasty. We made follow-up cut-offs 30-days, 6 weeks, 90-days, and one year after hospital discharge determining hip dislocation rate and patients' survival. RESULTS The women population represented 78.7%, and the mean age of the population was 85.2 ± 6.7 years. Hip prosthesis dislocation incidence was 1.9% in the first 90-days after discharge, representing 91.54% of primary dislocations yearly noted. We reported statistically significant increased mortality rates of patients presenting at least one hip prosthesis dislocation event (from 16.0% to 24.6% at 90-day after discharge, and 29.5% to 44.7% at one year), and also significantly decreasing patient survival function at 90-day (P = .016) and one-year follow-up (P < .001). The recurrent dislocation events (26.15%) showed even higher mortality rates (up to 60.6%, p < .001). The multivariate Cox regression model determined that prosthesis dislocation was the only significant variable (P = .035) affecting patient survival, increasing the risk of dying before one year of follow-up by 2.7 times. DISCUSSION Our study stands for the standalone hip prosthesis dislocation entailing a higher risk of death after hip fracture hemiarthroplasty in the older population.

Abstract
This study investigated whether decreasing the femoral head size, in addition to performing a posterior capsular closure and short external rotator repair, influences the historical rate of dislocation after conversion of a failed hemiarthroplasty (HA) to a total hip arthroplasty (THA) through a posterior approach. We reviewed 15 patients from our prospective arthroplasty database who underwent a conversion from an HA to a THA with closure of the posterior capsule, had downsizing of the femoral head, and had at least a 2-year follow-up. Patients were clinically observed to determine whether their hip dislocated postoperatively or required re-revision. Radiographs were evaluated to assess for known risk factors for dislocation, including component position and restoration of hip biomechanics. The femoral head size was downsized from a mean of 45 mm (range, 42-57 mm) preoperatively to a mean of 32 mm (range, 28-36 mm) postoperatively (P<.001). Femoral heads sized 36, 32, and 28 mm were used in the revision of 4, 5, and 6 hips, respectively. At the mean 84-month follow-up (range, 24-156 months), there were no dislocations. Attention to surgical technique and closing the posterior capsule can decrease the historically high dislocation rate associated with converting an HA to a total hip replacement using the posterolateral approach. Despite substantial reduction in size of the prosthetic femoral head, there were no postoperative dislocations with closure of the posterior capsule. Downsizing the femoral head during revision THA should be avoided; however, if not feasible, closure of the posterior capsule can offset the otherwise increased risk of dislocation.

Abstract
INTRODUCTION Surgical treatment options for patients with an intracapsular fracture of the femoral neck (FFN) are primary osteosynthesis as a femoral head-spearing technique or primary (hemi)arthroplasty. The most common complications after primary osteosynthesis, such as avascular necrosis (AVN) or non-union, can result in conversion to Total Hip Arthroplasty (cTHA). Data concerning complications and survival rates of cTHA in comparison to primary Total Hip Arthroplasty (pTHA) after FFN are limited due to the absence of well-designed studies. METHODS A multicentre retrospective cohort study was conducted in three Dutch hospitals comparing the rate of postoperative dislocations, periprosthetic fractures, prosthetic joint infections, blood loss during surgery (>1000 mL), postoperative cardiac- and pulmonary complications after pTHA and cTHA in the first year after surgery. As a secondary outcome implant survival of pTHA and cTHA in terms of revision rates was evaluated. RESULTS In total 548 patients were included (pTHA n = 264 and cTHA n = 284) with a mean follow-up of 5 years (±3.5 SD). No significant differences were found in postoperative complications rates. The revision rate in the pTHA group was 7.2% in comparison to 7.7% in the cTHA group (p = 0.81). No difference in the short-term implant survival was found between both groups (p = 0.81). CONCLUSION This study showed no significant differences in terms of postoperative complication rates in the first year after pTHA and cTHA in patients with FFN. Also, no significant difference in short-term implant survival of primary and conversion total hip arthroplasty was found.

Abstract
AIMS Patients with femoral neck fractures (FNFs) treated with total hip arthroplasty (THA) have an almost ten-fold increased risk of dislocation compared to patients undergoing elective THA. The surgical approach influences the risk of dislocation. To date, the influence of differing head sizes and dual-mobility components (DMCs) on the risk of dislocation has not been well studied. METHODS In an observational cohort study on 8,031 FNF patients with THA between January 2005 and December 2014, Swedish Arthroplasty Register data were linked with the National Patient Register, recording the total dislocation rates at one year and revision rates at three years after surgery. The cumulative incidence of events was estimated using the Kaplan-Meier method. Cox multivariable regression models were fitted to calculate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for the risk of dislocation, revision, or mortality, stratified by surgical approach. RESULTS The cumulative dislocation rate at one year was 8.3% (95% CI 7.3 to 9.3) for patients operated on using the posterior approach and 2.7% (95% CI 2.2 to 3.2) when using the direct lateral approach. In the posterior approach group, use of DMC was associated with reduced adjusted risk of dislocation compared to 32 mm heads (HR 0.21 (95% CI 0.07 to 0.68); p = 0.009). This risk was increased with head sizes < 32 mm (HR 1.47 (95% CI 1.10 to 1.98); p = 0.010). Neither DMC nor different head sizes influenced the risk of revision following the posterior approach. Neither articulation was associated with a statistically significantly reduced adjusted risk of dislocation in patients where the direct lateral approach was performed, although this risk was estimated to be HR 0.14 (95% CI 0.02 to 1.02; p = 0.053) after the use of DMC. DMC inserted through a direct lateral approach was associated with a reduced risk of revision for any reason versus THA with 32 mm heads (HR 0.36 (95% CI 0.13 to 0.99); p = 0.047). CONCLUSION When using a posterior approach for THA in FNF patients, DMC reduces the risk of dislocation, while a non-significant risk reduction is seen for DMC after use of the direct lateral approach. The direct lateral approach is protective against dislocation and is also associated with a lower rate of revision at three years, compared to the posterior approach.

Abstract
BACKGROUND Previous randomized studies have suggested that there is no short-term difference between the risk of revision following total hip arthroplasty (THA) and hemiarthroplasty (HA) for hip fracture in elderly patients. The aim of the present study was to compare the long-term revision rates of primary THA and HA for femoral neck fracture in order to determine whether unipolar or bipolar HA increases the all-cause risk of revision in patients 50 to 79 years old. METHODS Data for 36,188 patients who underwent primary arthroplasty, including 13,035 unipolar and 8,220 bipolar HAs and 14,863 THAs, from September 1, 1999, to December 31, 2019, were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Unadjusted analyses were performed, as well as analyses adjusted for age, sex, femoral cement, and procedure year. The primary outcome was time to first revision for any cause. Secondary analyses were performed for the reason for revision (i.e., infection, dislocation, and periprosthetic fracture). Instrumental variable analysis of hospital preference (for either HA or THA) was performed in order to mitigate the effect of any unmeasured confounding. All analyses were restricted to hospitals performing at least 10 procedures in the prior year. RESULTS A total of 18,955 procedures were available for the comparison of modular unipolar HA to THA. Both the adjusted analysis performed with use of Cox proportional hazards (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.64 to 2.31; p < 0.001) and the instrumental variable analysis (HR, 2.82; 95% CI, 1.89 to 4.22; p < 0.001) demonstrated a higher risk of revision following modular unipolar HA compared with THA from 3 months postoperatively. A total of 13,168 procedures were available for the comparison of bipolar HA to THA. The adjusted analysis performed with use of Cox proportional hazards showed a significantly higher risk of revision for bipolar HA (HR, 1.29; 95% CI, 1.08 to 1.54; p = 0.01). The instrumental variable analysis showed a similar effect size that was not significant (HR, 1.27; 95% CI, 0.91 to 1.78; p = 0.16). CONCLUSIONS Bipolar HA and THA demonstrated no significant difference in revision risk at long-term follow-up. Unipolar HA demonstrated higher risk of revision from 3 months postoperatively compared to THA. The higher risk of revision for dislocation observed following THA may be offset by the higher risk of revision for acetabular erosion or pain following bipolar HA, resulting in more equivalent revision risk.

Abstract
INTRODUCTION Advanced age is considered a major risk factor for postoperative complications in total hip arthroplasty (THA). Consequently, older patients undergoing THA may require more detailed pre-procedural examinations and more healthcare resources postoperatively than younger patients. The purpose of this study was to compare discharge parameters and complication rates of THA in patients ⩾90 years old to those <90 years old. METHODS A retrospective review of 14,824 THA patients from 2011 to 2021 at a high-volume, urban academic centre was conducted. Patients ⩾90 years old were propensity-matched to a control group of patients aged <90 years old. Patient demographics, surgical time, hospital length of stay (LOS), discharge disposition, and 90-day revision, readmission, and mortality rates were collected. Demographic differences and outcomes were assessed using chi-square and independent sample t-tests. RESULTS After propensity matching, the average age in the younger cohort (YC, n = 54) was 75.81 ± 7.89, and 91.61 ± 1.73 for the older cohort (OC, n = 54). The OC had a longer LOS than the YC (mean 3.90 vs. 3.06 days; p = 0.031). Discharge disposition significantly differed (p = 0.007); older patients were more likely to be discharged to skilled nursing facilities (33.3% vs. 14.8%) or acute rehabilitation centres (14.8% vs. 3.7%) and less likely to be discharged to prior place of residence (home self-managed/home with services, 51.9% vs. 79.6%). There was no significant difference in surgical time (93.87 ± 29.75 vs. 96.09 ± 26.31 min; p = 0.682), 90-day revision rate (3.7% vs. 0%; p = 0.153), 90-day readmission rate (9.4% vs. 3.7%; p = 0.543), and 90-day mortality rate (1.9% vs. 1.9%; p = 1.000). CONCLUSIONS Although THA patients over 90 years of age had a longer LOS and differing discharge disposition, these patients had similar complications compared to their younger counterparts. Thus, our study supports similar efficacy of THA in patients 90 years and older relative to younger THA candidates.

Abstract
Background: Huo Xue Tong Luo (HXTL) capsules are an oral preparation that could relieve pain and ameliorate osteonecrosis in patients with asymptomatic osteonecrosis of femoral head (ONFH). We wanted to verify whether it could be a treatment option for ARCO stage II ONFH. Methods: A total of 44 patients (66 hips) with ARCO stage II ONFH were recruited from June 1996 to October 2013 (clinical trial registry number: ChiCTR-RPC-15006,290). HXTL capsules were given under a specific protocol, and the endpoint was set as femoral head collapse. The clinical indicators [including visual analog scale (VAS) and Harris Hip Score (HHS)] and radiological indicators [including Tonnis classification, ARCO stage, Japanese Investigation Committee (JIC) classification, lateral preserved angle (LPA), anterior preserved angle (APA), and combined preserved angle (CPA)] before and after treatment were compared. Kaplan–Meier survival analysis and Cox regression analysis were used to identify the risk factors associated with femoral head collapse. Result: Twenty-six males and 18 females with an average age of 38.3 ± 2.8 were followed for an average of 7.95 years. Forty-six of the 66 (69.7%) hips had no progression in pain or collapse, and patients exhibited a higher HHS (p < 0.05) after therapy. Twenty of the 66 (30.3%) hips progressed in Tonnis classification and ARCO stage, but only one of the 66 (1.5%) hips required total hip arthroplasty (THA). The Kaplan–Meier survivorship curve suggested that the survival rates were 96.97% at 5 years, 69.15% at 10 years, and 40.33% at 15 years. Patients with type A necrotic lesions on anteroposterior (AP) and frog-leg lateral (FLL) radiographs revealed 100% survival rates. Multivariate Cox regression analysis revealed that patients with an LPA ≤ 60.9 exhibited a 3.87 times higher risk of collapse of the femoral head [95% confidence interval (CI), 1.241–5.673] than did those patients with an LPA>60.9. Conclusion: HXTL capsules could be a treatment option for ARCO stage II ONFH, resulting in improved hip function and delayed progression to femoral head collapse, especially when the anterior and lateral portions of the femoral head were not affected. However, an LPA of less than 60.9° may be a risk factor for collapse of the femoral head. Clinical Trial Registration:http://www.chictr.org.cn/showproj.aspx?proj=10829, identifier ChiCTR-OPC-15007030

Abstract
AIMS Total hip arthroplasty (THA) with dual-mobility components (DM-THA) has been shown to decrease the risk of dislocation in the setting of a displaced neck of femur fracture compared to conventional single-bearing THA (SB-THA). This study assesses if the clinical benefit of a reduced dislocation rate can justify the incremental cost increase of DM-THA compared to SB-THA. METHODS Costs and benefits were established for patients aged 75 to 79 years over a five-year time period in the base case from the Canadian Health Payer's perspective. One-way and probabilistic sensitivity analysis assessed the robustness of the base case model conclusions. RESULTS DM-THA was found to be cost-effective, with an estimated incremental cost-effectiveness ratio (ICER) of CAD $46,556 (£27,074) per quality-adjusted life year (QALY). Sensitivity analysis revealed DM-THA was not cost-effective across all age groups in the first two years. DM-THA becomes cost-effective for those aged under 80 years at time periods from five to 15 years, but was not cost-effective for those aged 80 years and over at any timepoint. To be cost-effective at ten years in the base case, DM-THA must reduce the risk of dislocation compared to SB-THA by at least 62%. Probabilistic sensitivity analysis showed DM-THA was 58% likely to be cost-effective in the base case. CONCLUSION Treating patients with a displaced femoral neck fracture using DM-THA components may be cost-effective compared to SB-THA in patients aged under 80 years. However, future research will help determine if the modelled rates of adverse events hold true. Surgeons should continue to use clinical judgement and consider individual patients' physiological age and risk factors for dislocation. Cite this article: Bone Joint J 2021;103-B(12):1783-1790.

Abstract
BACKGROUND The purpose of this study was to compare the mortality rate between patients undergoing hemiarthroplasty (HA) and those undergoing total hip arthroplasty (THA) in two age groups: patients aged 65-79 years (non-octogenerian) and patients aged ≥ 80 years (octogenarian). METHODS We identified elderly (aged ≥ 65 years) femoral neck fracture patients who underwent primary THA or HA from January 1, 2005 to December 31, 2015 in South Korea using the Health Insurance and Review and Assessment database; the nationwide medical claim system of South Korea. We separately compared the mortality rate between the HA group and THA group in two age groups. A generalized estimating equation model with Poisson distribution and logarithmic link function was used to calculate the adjusted risk ratio (aRR) of death according to the type of surgery. RESULTS The 3,015 HA patients and 213 THA patients in younger elderly group, and 2,989 HA patients and 96 THA patients in older elderly group were included. In the younger elderly group, the mortality rates were similar between the two groups. In older elderly group, the aRR of death in the THA group compared to the HA group was 2.16 (95% confidence interval [CI], 1.20-3.87; P = 0.010) within the in-hospital period, 3.57 (95% CI, 2.00-6.40; P < 0.001) within 30-days, and 1.96 (95% CI, 1.21-3.18; P = 0.006) within 60-days. CONCLUSIONS In patients older than 80 years, THA was associated with higher postoperative mortality compared to HA. We recommend the use of HA rather than THA in these patients.

Cementless Fixation Is Associated With Increased Risk of Early and All-Time Revision After Hemiarthroplasty But Not After THA for Femoral Neck Fracture: Results From the American Joint Replacement Registry. Clin Orthop Relat Res 2021; 479:2194-2202. [PMID: 34398846 PMCID: PMC8445546 DOI: 10.1097/corr.0000000000001932] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 07/14/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND Despite ample evidence supporting cemented femoral fixation for both hemiarthroplasty and THA for surgical treatment of displaced femoral neck fractures, cementless fixation is the preferred fixation method in the United States. To our knowledge, no nationally representative registry from the United States has compared revision rates by fixation for this surgical treatment. QUESTION/PURPOSE After controlling for relevant confounding variables, is femoral fixation method (cemented or cementless) in hemiarthroplasty or THA for femoral neck fracture associated with a greater risk of (1) all-cause revision or (2) revision for periprosthetic fracture? METHODS Patients with Medicare insurance who had femoral neck fractures treated with hemiarthroplasty or THA reported in the American Joint Replacement Registry database from 2012 to 2017 and Centers for Medicare and Medicaid Services claims data from 2012 to 2017 were analyzed in this retrospective, large-database study. Of the 37,201 hemiarthroplasties, 42% (15,748) used cemented fixation and 58% (21,453) used cementless fixation. Of the 7732 THAs, 20% (1511) used cemented stem fixation and 80% (6221) used cementless stem fixation. For both the hemiarthroplasty and THA cohorts, most patients were women and had cementless femoral fixation. Early revision was defined as a procedure that occurred less than 90 days from the index procedure. All patients submitted to the registry were included in the analysis. Patient follow-up was limited to the study period. No patients were lost to follow-up. Due to inherent limitations with the registry, we did not compare medical complications, including deaths attributed directly to cemented fixation. A logistic regression model including the index arthroplasty, age, gender, stem fixation method, hospital size, hospital teaching affiliation, and Charlson comorbidity index score was used to determine associations between the index procedure and revision rates. RESULTS For the hemiarthroplasty cohort, risk factors for any revision were cementless stem fixation (odds ratio 1.42 [95% confidence interval 1.20 to 1.68]; p < 0.001), younger age (OR 0.96 [95% CI 0.95 to 0.97]; p < 0.001), and higher Charlson comorbidity index (OR 1.06 [95% CI 1.02 to 1.11]; p = 0.004). Risk factors for early revision were cementless stem fixation (OR 1.77 [95% CI 1.43 to 2.20]; p < 0.001), younger age (OR 0.98 [95% CI 0.97 to 0.99]; p < 0.001), and higher Charlson comorbidity index (OR 1.09 [95% CI 1.04 to 1.15]; p < 0.001). Risk factors for revision due to periprosthetic fracture were cementless fixation (OR 6.19 [95% CI 3.08 to 12.42]; p < 0.001) and higher Charlson comorbidity index (OR 1.16 [95% CI 1.06 to 1.28]; p = 0.002). Risk factors for early revision due to periprosthetic fracture were cementless fixation (OR 7.38 [95% CI 3.17 to 17.17]; p < 0.001), major teaching hospital (OR 2.10 [95% CI 1.08 to 4.10]; p = 0.03), and higher Charlson comorbidity index (OR 1.20 [95% CI 1.09 to 1.33]; p < 0.001). For the THA cohort, there were no associations. CONCLUSION These data suggest that cemented fixation should be the preferred technique for most patients with displaced femoral neck fractures treated with hemiarthroplasty. The fact that stem fixation method did not affect revision rates for those patients with displaced femoral neck fractures treated with THA may be due to current practice patterns in the United States. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
BACKGROUND Registry data suggest increasing rates of early revisions after total hip arthroplasty (THA). We sought to analyze modes of failure over time after index THA to identify risk factors for early revision. METHODS We identified 208 aseptic femoral revision THAs performed between February 2011 and July 2019 using an institutional database. We compared demographics, diagnoses, complications, and resource utilization between aseptic femoral revision THA occurring within 90 days (early), 91 days to 2 years (mid), and greater than 2 years (late) after index arthroplasty. RESULTS Early revisions were 33% of revisions at our institution in the time period analyzed. Periprosthetic fractures were 81% of early, 27% of mid, and 21% of late femoral revisions (P < .01). Women were more likely to have early revisions than men (75% vs 53% of mid and 48% of late revisions; P < .01). Patients who had early revisions were older (67.97 ± 10.06) at the time of primary surgery than those who had mid and late revisions (64.41 ± 12.10 and 57.63 ± 12.52, respectively, P < .01). Index implants were uncemented in 99% of early, 96% of mid, and 64% of late revisions (P < .01). Early revisions had longer postoperative length of stay (4.4 ± 3.3) than mid and late revisions (3.0 ± 2.2 and 3.7 ± 2.1, respectively, P = .02). In addition, 58% of early revisions were discharged to an inpatient facility compared with 36% of mid and 41% of late revisions (P = .03). CONCLUSION Early aseptic femoral revisions largely occur in older women with uncemented primary implants and primarily due to periprosthetic fractures. Reducing the incidence of periprosthetic fractures is critical to decreasing the large health care utilization of early revisions.

Abstract
BACKGROUND Femoral neck fractures (FNFs) are one of the most common injuries in the elderly. Treatment is either internal fixation or primary arthroplasty. The main aim of this study is to assess the risk factors associated with fixation failure leading to further arthroplasty in FNFs treated with cannulated screws. METHODS Data on internal fixations of FNFs performed at Turku University Hospital between January 1, 2012 and December 31, 2017 were collected retrospectively from the patient database. Radiographical measurements were performed for preoperative displacement and posterior tilt, postoperative displacement, reduction quality, and implant shaft angle. RESULTS Altogether 301 cases were included in the study. The overall reoperation rate was 25% and conversion to arthroplasty was performed in 16% of cases. In the multiple variant analysis, adjusted for age and gender, nondisplaced fractures with a 0°-20° preoperative posterior tilt had a significantly lower risk of later conversion to arthroplasty than did nondisplaced fractures with a ≤0° or ≥20° posterior tilt (odds ratio [OR] 4.0, 95% confidence interval [Cl] 1.8-8.6, P = .0005) and displaced fractures (OR 7.2, 95% CI 3.0-17.4, P < .0001). No statistically significant association was found between preoperatively nondisplaced fractures with a <0° or ≥20° posterior tilt and displaced fractures (OR 0.6, 95% Cl 0.2-1.3, P = .2). CONCLUSION Displaced fractures and fractures with a preoperative posterior tilt of <0° or ≥20° have a considerably increased risk of reoperation and conversion to arthroplasty. Primary arthroplasty should be considered as treatment for displaced FNFs and fractures with >20° or <0° posterior tilt, especially in fragile patients, to avoid further operations.

Abstract
OBJECTIVE Restoration of pain-free joint function by implantation of a bipolar hemiarthroplasty via anterolateral approach. INDICATIONS Elderly multimorbid patients >70 years, age >80 years, low functional demand. CONTRAINDICATIONS Infection. Relative contraindications: dysplastic hip joint. SURGICAL TECHNIQUE Supine position. Anterolateral approach. Incision of the iliotibial tract and entering the interval between tensor fasciae latae muscle/gluteus medius muscle. Capsulotomy. Femoral neck osteotomy. Removal of the femoral head and determination of the size of the bipolar prosthetic head. Inspection of the acetabulum. Adduction, external rotation ("figure 4" position) of the leg. Medullary preparation of the femur with rasps up to the correct level and size of the planed stem. Ensure the correct rotation of anteversion (10-15°). Trial reduction and examination of hip stability. Verification with image intensifier. Cement restrictor, jet lavage, drying the medullary canal, injection of bone cement and insertion of the prosthetic stem. Assembly/attachment of the definitive bipolar head to the stem. Reduction of the joint. Wound closure. POSTOPERATIVE MANAGEMENT Early mobilization and full weight bearing. Limitation of hip flexion >90°, rotation and adduction for 6 weeks. Venous thromboembolism prophylaxis. Osteoporosis evaluation and management. Clinical-radiological control (after 6 weeks, 1/3/5 years). RESULTS The implantation of a cemented hemiarthroplasty using the anterolateral approach is a muscle-sparing and dislocation-safe surgical procedure with a low risk of revision, which enables early patient mobilization and a good hip joint function.

Abstract
AIMS Previous studies have already shown early proximal ingrowth, fast osseous integration, and a stable fit of the uncemented Symax hip stem, with excellent clinical and radiographic performance. Aims were to evaluate cumulative revision rates and reasons for revision of the Symax hip stem using Dutch Arthroplasty Register (LROI) data and to assess possible associations between patient characteristics and revision rate of the Symax hip stem. PATIENTS AND METHODS All total hip arthroplasties with the uncemented Symax hip stem registered in the LROI between 2007 and 2017 were included (n = 5,013). Kaplan-Meier survival analysis was performed to assess the cumulative 1, 5 and 7-year revision percentages. Cox proportional hazard regression analysis was performed to assess the association between patient and procedural characteristics, and revision arthroplasty of the stem. RESULTS Cumulative 1, 5, and 7-year revision rates (with 95% confidence interval (CI)) for revision of any component were 1.5% (CI 1.2%-1.8%), 3.2% (CI 2.7%-3.7%), and 3.8% (CI 3.1%-4.4%) respectively. Cumulative 1, 5, and 7-year stem revision rates of the Symax hip stem were 0.9% (CI 0.6%-1.1%), 1.5% (CI 1.1%-1.9%), and 1.7% (CI 1.3%-2.1%) respectively. Periprosthetic fractures (n = 35) and loosening of the stem (n = 30) were the most common reasons for revision of the stem. Revision of the stem was associated with acute fracture as primary diagnosis (Hazard Ratio (HR) 2.4 (CI 1.3-4.3)), or history of a previous surgery to the affected hip (HR 2.7 (CI 1.4-5.2)). CONCLUSION This population-based registry study shows revision rates for the Symax hip stem comparable to those for best performing uncemented total hip arthroplasties in the Netherlands. Primary diagnosis of an acute fracture, and history of previous surgery on the affected hip, were significantly associated risk factors for revision of the Symax hip stem, and we discourage the use of the Symax hip stem in these patients.

Abstract
OBJECTIVE To examine the risk factors for new chronic opioid use in elderly patients who underwent hip fracture surgery. DESIGN Prospective population-based cohort study. SETTING AND PARTICIPANTS Using Danish nationwide health registries, we identified all opioid non-user patients aged ≥65 years who had undergone hip fracture surgery from 2005 to 2016 and were alive within the first year following surgery. MAIN OUTCOME MEASURES New chronic opioid use defined by the dispensing of at least two prescription opioids within two of the last three quarters during the first year following surgery. RESULTS We identified 37 202 opioid non-user patients who underwent hip fracture surgery. Of these, 5497 (15%) developed new chronic opioid user within 1 year of surgery. Risk factors for new chronic opioid use were Body Mass Index (BMI) of <18.5 (adjusted OR (aOR) 1.22, 95% CI 1.09 to 1.36), BMI of 25.0-29.9 (aOR 1.12, 95% CI 1.04 to 1.21) and BMI of ≥30 (aOR 1.57, 95% CI 1.40 to 1.76) with BMI 18.6-24.9 as reference, a pertrochanteric/subtrochanteric fracture (aOR 1.27, 95% CI 1.20 to 1.34) with femoral neck fracture as reference, preoperative use (vs no-use) of non-steroidal anti-inflammatory drug (aOR 1.68, 95% CI 1.55 to 1.83), selective serotonin reuptake inhibitor (aOR 1.42, 95% CI 1.32 to 1.53), antidepressants (aOR 1.36, 95% CI 1.24 to 1.49), antipsychotics (aOR 1.21, 95% CI 1.07 to 1.35), corticosteroids (aOR 1.54, 95% CI 1.35 to 1.76), statins (aOR 1.09, 95% CI 1.02 to 1.18), antibiotics (aOR 1.32, 95% CI 1.22 to 1.42), antiosteoporosis drugs (aOR 1.33, 95% CI 1.19 to 1.49) and anticoagulatives (aOR 1.24, 95% CI 1.17 to 1.32). Presence of cardiovascular comorbidities, diabetes, gastrointestinal diseases, dementia, chronic obstructive pulmonary disease or renal diseases was further identified as a risk factor. CONCLUSION In this large nationwide cohort study, we identified several risk factors associated with new chronic opioid use after hip fracture surgery among patients who were alive within the first year following surgery. Although not all factors are modifiable preoperative, this will allow clinicians to appropriately counsel patients preoperatively and tailor postoperative treatment.

Abstract
PURPOSE Early mortality (< 30 days) in hip fracture patients is as high as 9.6%. Several risk assessment tools have been developed to identify patients at high risk for early mortality. Among them, the Almelo Hip Fracture Score (AHFS) was developed recently and showed promising results. Until now, this tool has not been validated; therefore, we aim to perform an external validation of the AHFS. METHODS On admission, AHFS variables were prospectively collected. The prospectively collected data were used retrospectively to externally validate the AHFS in a cohort of hip fracture patients that were admitted to a hospital in Delft (Delft cohort). The AHFS score was retrospectively calculated for all hip fracture patients meeting the inclusion criteria. The characteristics of the Delft Cohort, AHFS score, sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve were calculated and compared to the original Almelo cohort, in which the AHFS was developed. RESULTS 422 patients of 70 years and older were included. Mortality within 30 days was 7.6% and similar to the 7.5% observed in the Almelo cohort. For the high-risk cut-off point, specificity was 95.4% in the Delft Cohort vs. 92.5% in the Almelo Cohort, and sensitivity for the low-risk cut-off point was 75.9 vs. 78.1% in the Almelo Cohort. The area under the ROC curve was 0.70 (95% CI 0.60-0.79) compared to 0.82 in the Almelo cohort. CONCLUSIONS The validity of the score was acceptable and comparable to the values in the Almelo cohort. This score might be used to identify patients at high risk for early mortality.

Abstract
BACKGROUND There remains much international practice variation regarding the choice of a unipolar or bipolar prosthesis design for displaced femoral neck fractures that are treated with hemiarthroplasty. The purpose of the present study was to compare revision rates following primary hemiarthroplasty for femoral neck fracture to determine if the unipolar hemiarthroplasty design increases the risk of revision arthroplasty for all causes. METHODS Instrumental variable analysis was performed with use of data that had been entered into the Australian Orthopaedic Association National Joint Replacement Registry from September 1, 1999, to December 31, 2018. Sixty-two thousand, eight hundred and seventy-five patients with femoral neck fractures that were treated with primary modular unipolar or bipolar hemiarthroplasty procedure were analyzed. Hospital preference for prosthesis design in the 12 months prior to the index procedure was used as an instrument to adjust for unmeasured confounding. The primary outcome was time to first revision for any cause. Secondary analyses were performed on the reason for revision (infection, dislocation, periprosthetic fracture, or acetabular erosion), the use of cement femoral stem fixation, and the type of stem (polished or matte). RESULTS Modular unipolar hemiarthroplasty was associated with a higher rate of revision at >2.5 years (hazard ratio [HR], 1.86; 95% confidence interval [CI], 1.46 to 2.36; p < 0.001), but there was no difference between the groups before 2.5 years (HR, 0.98; 95% CI, 0.85 to 1.13; p = 0.79). Protective factors for revision included female sex (HR, 0.82; 95% CI, 0.74 to 0.9), use of cemented fixation (HR, 0.69; 95% CI, 0.62 to 0.77), and surgery performed in a public hospital setting (HR 0.79; 95% CI, 0.70 to 0.89). Modular unipolar prostheses had a greater risk of revision for acetabular erosion, particularly in later time periods (HR at ≥5.5 years, 5.10; 95% CI, 2.40 to 10.83; p < 0.001), while being protective against periprosthetic fractures (HR, 0.72; 95% CI, 0.59 to 0.87; p < 0.001) at all time points. There was no difference in terms of the risk of revision for infection, dislocation, or stem type. CONCLUSIONS Bipolar hemiarthroplasty designs resulted in a lower risk of revision than unipolar designs. Unipolar hemiarthroplasties are justified for patients with femoral neck fracture and a shorter life expectancy (≤2.5 years). LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Background and purpose - Dislocation is one of the most frequent reasons for cup revision after total hip arthroplasty (THA) for an acute fracture. A dual mobility cup (DMC) might reduce this risk. We determined the cup revision rate after THA for an acute fracture according to type of cup.Patients and methods - All THAs for an acute fracture registered in the Dutch Arthroplasty Register (LROI) during 2007-2019 were included (n = 11,857). Type of cup was divided into DMC and unipolar cup (UC). Competing risk analyses were performed with cup revision for any reason as endpoint. Multivariable Cox regression analyses with outcome cup revision were performed adjusted for sex, age, ASA class, and surgical approach, stratified for UC THA with femoral head size of 32 mm and 22-28 mm.Results - A DMC was used in 1,122 (9%) hips. The overall 5-year cup revision rate for any reason after THA for acute fracture was 1.9% (95% CI 1.6-2.2). Cup revision for dislocation within 5 years was performed in 1 of 6 DMC THAs versus 108 of 185 (58%) UC THAs. Univariable Cox regression analyses showed no statistically significant difference in cup revision rate between DMC and UC (HR = 0.8; CI 0.4-1.5). Multivariable Cox regression analyses showed lower risk of cup revision in DMC THA (n = 1,122) compared with UC THA with 22-28 mm femoral head size (n = 2,727) (HR = 0.4; CI 0.2-0.8).Interpretation - The 5-year cup cumulative incidence of revision after THA for acute fracture was comparable for DMC and UC THA. However, DMC THA had a lower risk of cup revision than UC THA with 22-28 mm femoral head.

Abstract
BACKGROUND Various factors, other than the quality of surgery, may influence clinical outcomes of hip fracture patients. We aimed to evaluate the relative impact of several factors on functional outcome, quality of life, re-fracture and mortality rates following surgery for hip fractures. METHODS We studied 498 (62.2%) women and 302 (37.8%) men with a mean age of 81.3 years (range, 60-95) with hip fractures (femoral neck and pertrochanteric). The mean follow-up was 74 months (range 58-96). Various patient-related and surgery-related parameters were recorded and correlated to both objective and subjective mobility, functional recovery and quality of life scales. Mortality and re-fracture rates were also evaluated. RESULTS Using multiple regression analysis, age >80 years (p = 0.000; 95% CI, 1.077-1.143) and ASA score III and IV (p = 0.000; 95% CI, 2.088-3.396) (both non-modifiable factors) both proved to be independent (s.s.) factors affecting mortality rates. Age <80 years (p = 0.000; 95% CI, 0.932-0.974), surgery delay less (modifiable factor) than 48 hours (p = 0.046; 95% CI, 0.869-0.999), low dementia CDR index (p = 0.005; 95% CI, 0.471-0.891) (non-modifiable factor), and osteoporosis medical treatment (modifiable factor) (p = 0.006; 95% CI, 0.494-0.891) were shown to be independent (s.s.) factors affecting HOOS-symptoms. Osteoporosis medical treatment used proved to be an independent (s.s.) factor affecting HOOS-daily activities (p = 0.049; 95% CI, 0.563-1.000) and quality of life (E-Qol-5D) (p = 0.036; 95% CI, 0.737-1.325). CONCLUSIONS A hip fracture patient aged <80 years old, with an ASA I-II, with low dementia CDR index and on osteoporosis medication has a better chance of an improved outcome (winner patient).

Abstract
Background We performed an updated systematic review and meta-analysis which enrolled 25 prospective randomized controlled trials (RCTs) to compare the outcomes between total hip arthroplasty (THA) and hemiarthroplasty (HA) in patients with femoral neck fractures (FNFs). Methods We searched English databases which included PubMed, Embase (vis OvidSP), The Cochrane Library, and Web of Science, and Chinese databases Chinese National Knowledge Infrastructure (CNKI), VIP, Wang Fang, and China Biology Medicine Disc (CBM) in July 2020. The quality of each study was assessed according to the Cochrane Collaboration’s Risk of Bias. Risk ratios (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were pooled with random-effects models. Data regarding baseline characteristics, hospital and surgery outcomes, clinical outcomes, patients’ quality of life, common complications, prothesis-related complications, mortality, and costs were reported. Results A total of 25 RCTs involving 3223 patients (1568 THA and 1655 HA) were included. THA had longer hospital length (WMD = 0.721, P < 0.0001) and surgery time (WMD = 20.044, P < 0.0001), and more blood loss compared with HA (WMD = 69.109, P < 0.0001). THA showed better ratings in the Harris Hip Score during follow-up periods between 1 and 5 years while no differences within 6 months and after 9 years. THA was associated with higher quality-of-life EuroQol-5 Dimension (EQ-5D) scores after 2 years of surgery but no difference within 1 year. There was no difference in common complications. THA had significant higher rate of dislocation (WMD = 1.897, P = 0.002) and lower acetabular erosion (WMD = 0.030, P = 0.001). For mortality, there was no difference during all the follow-up periods except for slightly higher 2-year mortality after surgery. Conclusion This meta-analysis demonstrates that THA has better medium-term functional results and quality of life and lower acetabular erosion rate, while HA shows better in reducing hospital stay, surgery time, and blood loss and also has lower dislocation rate.

Abstract
AIMS To evaluate the rate of dislocation following dual mobility total hip arthroplasty (DM-THA) in patients with displaced femoral neck fractures, and to compare rates of dislocation, surgical-site infection, reoperation, and one-year mortality between DM-THA and bipolar hemiarthroplasty (BHA). METHODS Studies were selected based on the following criteria: 1) study design (retrospective cohort studies, prospective cohort studies, retrospective comparative studies, prospective comparative studies, and randomized controlled studies (RCTs)); 2) study population (patients with femoral neck fracture); 3) intervention (DM-THA or BHA); and 4) outcomes (complications during postoperative follow-up and clinical results). Pooled meta-analysis was carried out to evaluate the dislocation rate after DM-THA and to compare outcomes between DM-THA and BHA. RESULTS A total of 17 studies (ten cohort studies on DM-THA and seven comparative studies of DM-THA and BHA) were selected. These studies included 2,793 patients (2,799 hips), made up of 2,263 DM-THA patients (2,269 hips) and 530 BHA patients (530 hips). In all, 16 studies were analyzed to evaluate dislocation rate after DM-THA. The cumulative dislocation rate was 4% (95% confidence interval (CI) 3 to 5). Seven studies were analyzed to compare the rates dislocation and surgical-site infection. The rate of dislocation was significantly lower in the DM-THA group than in the BHA group (risk ratio (RR) 0.3; 95% CI 0.17 to 0.53, p < 0.001, Z -4.11). There was no significant difference in the rate of surgical-site infection between the two groups (p = 0.580). Six studies reported all-cause reoperations. The rate of reoperation was significantly lower in the DM-THA group than in the BHA group (RR 0.5; 95% CI 0.32 to 0.78, p = 0.003, Z -3.01). Five studies reported one-year mortality. The mortality rate was significantly lower in the DM-THA group than in the BHA group (RR 0.58 95% CI 0.45 to 0.75, p < 0.0001, Z -4.2). CONCLUSION While the evidence available consisted mainly of non-randomized studies, DM-THA appeared to be a viable option for patients with displaced fractures of the femoral neck, with better reported rates of dislocation, reoperation, and mortality than BHA.

Abstract
OBJECTIVES HEALTH was a randomized controlled trial comparing total hip arthroplasty with hemiarthroplasty in low-energy displaced femoral neck fracture patients aged ≥50 years with unplanned revision surgery within 24 months of the initial procedure being the primary outcome. No significant short-term differences between treatment arms were observed. The primary objective of this secondary HEALTH trial analysis was to determine if any patient and surgical factors were associated with increased risk of revision surgery within 24 months after hip fracture. METHODS We analyzed 9 potential factors chosen a priori that could be associated with revision surgery. The factors included age, body mass index, major comorbidities, independent ambulation, type of surgical approach, length of operation, use of femoral cement, femoral head size, and degree of femoral stem offset. Our statistical analysis was a multivariable Cox regression using reoperation within 24 months of index surgery as the dependent variable. RESULTS Of the 1441 patients included in this analysis, 8.1% (117/1441) experienced reoperation within 24 months. None of the studied factors were found to be predictors of revision surgery (P > 0.05). CONCLUSION Both total and partial hip replacements are successful procedures in low-energy displaced femoral neck fracture patients. We were unable to identify any patient or surgeon-controlled factors that significantly increased the need for revision surgery in our elderly and predominately female patient population. One should not generalize our findings to an active physiologically younger femoral neck fracture population. LEVEL OF EVIDENCE Prognostic Level II.

Abstract
Purpose Bipolar hemiarthroplasty has been shown to have a lower rate of dislocation than total hip arthroplasty. However, as the influencing risk factors for bipolar hemiarthroplasty dislocation remain unclear, we aimed to analyse patient and surgeon-specific influencing risk factors for bipolar hemiarthroplasty dislocation. Methods We retrospectively analysed patients who were operated between 2012 and 2018 and had dislocated bipolar hemiarthroplasty and matched them to patients without a dislocated bipolar hemiarthroplasty, operated between 2018 and 2019. The study was limited to patients who received either a pre- or postoperative pelvic computed tomography. Besides demographic, morphologic, and physiologic data, we analysed duration of surgery; ASA score; Charlson Comorbidity Index; Almelo Hip Fracture Score; Parker Score; and acetabular morphology angles including acetabular anteversion angle, posterior acetabular sector angle, posterior wall angle, and acetabular roofing. Results We included nine patients with a dislocated bipolar hemiarthroplasty and 30 with a non-dislocated bipolar hemiarthroplasty. Patient-specific factors prompting a higher risk for dislocated bipolar hemiarthroplasty were longer duration of surgery (min) (115 ± 50 vs. 80 ± 27, p = 0.01); dementia (56% vs. 13%, p < 0.01); smaller posterior acetabular sector angle (°) (96 ± 6 vs. 109 ± 10, p < 0.01); and smaller posterior wall angle (°) (67 ± 6 vs. 77 ± 10, p = 0.02). Conclusion Dementia and insufficient posterior wall angle were associated with higher risk of dislocation in bipolar hemiarthroplasty

Abstract
AimsTo evaluate the rate of dislocation following dual mobility total hip arthroplasty (DM-THA) in patients with displaced femoral neck fractures, and to compare rates of dislocation, surgical-site infection, reoperation, and one-year mortality between DM-THA and bipolar hemiarthroplasty (BHA).MethodsStudies were selected based on the following criteria: 1) study design (retrospective cohort studies, prospective cohort studies, retrospective comparative studies, prospective comparative studies, and randomized controlled studies (RCTs)); 2) study population (patients with femoral neck fracture); 3) intervention (DM-THA or BHA); and 4) outcomes (complications during postoperative follow-up and clinical results). Pooled meta-analysis was carried out to evaluate the dislocation rate after DM-THA and to compare outcomes between DM-THA and BHA.ResultsA total of 17 studies (ten cohort studies on DM-THA and seven comparative studies of DM-THA and BHA) were selected. These studies included 2,793 patients (2,799 hips), made up of 2,263 DM-THA patients (2,269 hips) and 530 BHA patients (530 hips). In all, 16 studies were analyzed to evaluate dislocation rate after DM-THA. The cumulative dislocation rate was 4% (95% confidence interval (CI) 3 to 5). Seven studies were analyzed to compare the rates dislocation and surgical-site infection. The rate of dislocation was significantly lower in the DM-THA group than in the BHA group (risk ratio (RR) 0.3; 95% CI 0.17 to 0.53, p < 0.001, Z −4.11). There was no significant difference in the rate of surgical-site infection between the two groups (p = 0.580). Six studies reported all-cause reoperations. The rate of reoperation was significantly lower in the DM-THA group than in the BHA group (RR 0.5; 95% CI 0.32 to 0.78, p = 0.003, Z −3.01). Five studies reported one-year mortality. The mortality rate was significantly lower in the DM-THA group than in the BHA group (RR 0.58 95% CI 0.45 to 0.75, p < 0.0001, Z −4.2).ConclusionWhile the evidence available consisted mainly of non-randomized studies, DM-THA appeared to be a viable option for patients with displaced fractures of the femoral neck, with better reported rates of dislocation, reoperation, and mortality than BHA.

Abstract
Background and purpose - Femoral neck fractures are commonly treated with cemented or uncemented hemiarthroplasties (HA). We evaluated differences in mortality and revision rates in this fragile patient group.Patients and methods - From January 1, 2007 until December 31, 2016, 22,356 HA procedures from the Dutch Arthroplasty Register (LROI) were included. For each HA, follow-up until death, revision, or end of follow-up (December 31, 2016) was determined. The crude revision rate was determined by competing risk analysis. Multivariable Cox regression analyses were performed to evaluate the effect of fixation method (cemented vs. uncemented) on death or revision. Age, sex, BMI, Orthopaedic Data Evaluation Panel (ODEP) rating, ASA grade, surgical approach, and previous surgery were included as potential confounders.Results - 1-year mortality rates did not differ between cemented and uncemented HA. 9-year mortality rates were 53% (95% CI 52-54) in cemented HA compared to 56% (CI 54-58) in uncemented HA. Multivariable Cox regression analysis showed similar mortality between cemented and uncemented HA (HR 1.0, CI 0.96-1.1). A statistically significantly lower 9-year revision rate of 3.1% (CI 2.7-3.6) in cemented HA compared with 5.1% (CI 4.2-6.2) in the uncemented HA was found with a lower hazard ratio for revision in cemented compared with uncemented HA (HR 0.56, CI 0.47-0.67).Interpretation - Long-term mortality rates did not differ between patients with a cemented or uncemented HA after an acute femoral neck fracture. Revision rates were lower in cemented compared with uncemented HA.

Abstract
Centenarians population is proliferating, and hip fractures are responsible for more than 10% of all hospital admissions for centenarian patients, which represents a considerable challenge to patients and healthcare providers. Herein, we first report a case of a 111-year-old woman who suffered from a hip fracture and was successfully managed with cemented hemiarthroplasty surgery. In addition, we further reviewed case reports, news, and related studies to address the central points in managing hip fractures in the centenarian population.

Survival Rate and Application Number of Total Hip Arthroplasty in Patients With Femoral Neck Fracture: An Analysis of Clinical Studies and National Arthroplasty Registers. J Arthroplasty 2020; 35:1014-1022.

Abstract
BACKGROUND Total hip arthroplasty (THA) is an increasingly popular treatment option for fractured neck of femur (NOF). The primary aim of this study is to systematically review all literature on primary THA and hemiarthroplasty (HA) after fractured NOF to calculate an overall revision rate. Furthermore, we wanted to compare primary THA implantations after fractured NOF between different countries in terms of THA number per inhabitant. METHODS All clinical studies on THA and HA for femoral neck fractures between 1999 and 2019 were reviewed and evaluated with a special interest on revision rate. Revision rate was calculated as "revision per 100 component years." THA registers were compared between different countries with respect to the number of primary implantations per inhabitant. RESULTS THA studies showed a mean revision rate of 11.8% after 10 years, which was lower than a 24.6% 10-year revision rate for HA. We identified 8 arthroplasty registers that revealed an annual average incidence of THA for fractured NOF of 9.7 per 100,000 inhabitants. CONCLUSION This study showed that patients with THA were less likely to be revised at 10 years compared to HA. We found similar annual numbers of THAs for fractured NOF per inhabitant across countries. The results of this analysis can be used to rank present and future national THA numbers within an international context.

Abstract
INTRODUCTION There remains disagreement about the use of cemented or uncemented total hip arthroplasty (THA) for patients with a displaced intracapsular femoral neck fracture (FNF). The aim of this study was to assess implant survival, mortality, and postoperative complication rates of uncemented THA for a displaced intracapsular FNF in a single center. PATIENTS AND METHODS A cohort of 115 patients who received uncemented THAs for a displaced intracapsular FNF was retrospectively examined for implant survival in terms of revision and any reoperation, mortality, and postoperative complications. RESULTS The one- and five-year implant survival was 99.1% (95% confidence interval (CI) 97.3-100.9) and 97.8% (95% CI 94.7-100.9) for revision and 93.6% (95% CI 88.9-98.3) and 90.0% (95% CI 83.3-96.7) for any reoperation, respectively. Impaired mobility was significantly associated with lower implant survival (p = 0.01). The one, three, and 12 month mortality rates were 2.8% (95% CI 0-5.9), 3.7% (95% CI 0.2-7.2), and 5.6% (95% CI 1.3-9.9), respectively. Postoperative complication rate was 10% with 5% intra-operative fractures. CONCLUSIONS Contrary to earlier reports of results of uncemented THA for displaced FNF, the results of this study were comparable with those reported in the literature for cemented THA in displaced FNF with respect to implant survival, mortality, and complication rates. This indicates that uncemented THA could be a viable option for these patients. In future, the additional literature with a prospective design is needed to support and reinforce our conclusion.

Abstract
Background and purpose - Total hip arthroplasty (THA) is increasing as treatment of displaced femoral neck fractures. Several studies compare hemiarthroplasty (HA) with THA, but results vary and few studies report on medical complications. We examined the outcome of THA and HA with a focus on medical complications, hip complications, and death.Patients and methods - Data from the Swedish Hip Arthroplasty Register on 30,953 acute hip fracture patients treated with cemented THA or HA in 2005-2011 were cross-matched with Statistics Sweden for socioeconomic data and with the National Patient Register for diagnostic codes representing medical complications within 180 days or hip complications within the study period. Propensity score matching was used to create comparable groups based on age, sex, income, level of education, marital status, Elixhauser index, and year of surgery. Logistic regression models were created for each outcome.Results - 81% were treated with HA, 73% and 71% were female (HA and THA respectively). Matching resulted in 2 groups of 5,815 patients each. THA was associated with fewer medical complications (OR = 0.83; 95% CI 0.76-0.91) and lower 1-year mortality (OR = 0.42; CI 0.38-0.48), but more hip complications (OR = 1.31; CI 1.20-1.43).Interpretation - THA as treatment of hip fracture was associated with more hip-related complications than HA. The results on mortality and medical complications are, rather, influenced by residual confounding than by the implant design per se. An expansive use of THAs for hip fracture treatment, at the expense of HAs, is not recommended based on our findings if hip complications are to be avoided.

Abstract
INTRODUCTION Displaced femoral neck fractures in the elderly individuals may be treated with total hip arthroplasty (THA) or hip hemiarthroplasty (HHA). However, it is unclear what the short-term medical outcomes are related to these surgical options. The purpose of this study was to compare early postoperative outcomes in THA patients to those of HHA patients. METHODS In this study, we compared 30-day mortality, likelihood of still being in the hospital at 30 days, postoperative major and minor complications, discharge disposition, reoperation and readmission, length of stay, days from admission to surgery, and operative time between THA and HHA. Using the American College of Surgeons National Surgical Quality Improvement Project database, hip fracture patients ≥65 years old from 2008 to 2016 were identified. After propensity score matching, there were 2795 THAs and 2795 HHAs. To assess the effect of THA on the above-mentioned outcomes, bivariate regression models were created. RESULTS The THA patients ≥65 years old were at reduced risk for mortality (P = .029) and still being in the hospital at 30 days (P = .017). The THA patients were at an increased risk for minor complications (P = .011) and longer operative times (P < .001). However, THA patients were more likely to have a home discharge (P < .001). DISCUSSION Patients ≥65 years who underwent THA for hip fractures had reduced short-term mortality risk, were more likely to be discharged home, and had less likelihood of being in the hospital at 30 days. This is the first study to explore short-term outcomes in patients ≥65 and has direct implications for alternate payment and merit-based payment models. CONCLUSION As hip fracture treatment has come under scrutiny with respect to alternate payment models and merit-based incentive payments, this analysis of short-term outcomes warrants consideration when evaluating treatment pathways.

Low conversion rates toward total hip arthroplasty after hemiarthroplasty in patients under 75 years of age. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 29:1687-1691. [PMID: 31538270 DOI: 10.1007/s00590-019-02498-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Accepted: 07/08/2019] [Indexed: 01/27/2023]
Abstract
INTRODUCTION An intracapsular fracture of the femoral neck is frequent in the elderly. Patients can be treated with either total hip arthroplasty or hemiarthroplasty. There is a continuous discussion about the treatment in elderly patients who are still healthy, active and mentally untroubled. A potential consequence of hemiarthroplasty, especially in the relatively young elderly, could be conversion to total hip arthroplasty. The conversion rate must be acceptable, and clinical outcome must be sufficient to justify the treatment with hemiarthroplasty in this group of patients. This study evaluates the conversion rate of hemiarthroplasty to total hip arthroplasty and clinical outcome in patients under 75 years of age. METHODS This study identified 248 patients, younger than 75 years at time of operation, with a fracture of the femoral neck treated with hemiarthroplasty. Patient-reported outcome measurements (VAS pain during rest and activity and WOMAC) were assessed by telephone interviews. Furthermore, radiographic evaluation for the presence of acetabular wear was performed. RESULTS At a follow-up of 5.1 (0.9-9.6) years, the conversion rate was 7.3%. Mean VAS pain in rest was 0.89 (0-10), the mean VAS pain during activity was 2.2 (0-10), and the WOMAC showed a mean of 16.51 (0-64). At time of follow-up, 38.7% of patients had died. Radiographic evaluation of the unrevised group showed in one patient signs of acetabulum wear. CONCLUSION Hemiarthroplasty in the relatively young elderly after a fracture of the femoral neck demonstrates an acceptable conversion rate. Furthermore, unrevised patients show low complaints of pain. To prevent one conversion to total hip arthroplasty, 13.7 patients should be treated with total hip arthroplasty that will not undergo a conversion at a later stage. Therefore, hemiarthroplasty remains a viable treatment of femoral neck fractures in relatively young patients. There seems to be no space for standardized decision making concerning the choice of treatment. An individual approach is required.

Using Patient-Reported Outcomes to Predict Revision Arthroplasty Following Femoral Neck Fracture: Enhancing the Value of Clinical Registries through Data Linkage. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16081325. [PMID: 31013802 PMCID: PMC6517898 DOI: 10.3390/ijerph16081325] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Revised: 04/04/2019] [Accepted: 04/05/2019] [Indexed: 11/24/2022]
Abstract
The aim of this study was to determine the association between patient-reported outcome measures (PROMs) six months following femoral neck fracture after a low fall and future arthroplasty, and the factors associated with this. Six-month post-fracture PROMs were collected from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) for patients aged >55 years who were admitted for a femoral neck fracture after a low fall between March 2007 and June 2015. These cases were linked with those registered by Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) up to October 2016. Multivariable analysis was performed using a Cox proportional hazards model to determine factors associated with future arthroplasty, including six-month PROMs. Of the 7077 hip fracture patients registered by VOTOR during the study period, 2325 met the inclusion criteria. Internal fixation being used for the initial hip fracture surgery, being younger and having no pre-injury disability were all independently associated with future revision or conversion to arthroplasty. Out of all PROMs, reporting pain and discomfort six months post-fracture was associated with a 9.5-fold increase in the risk of future arthroplasty (95% CI: 3.81, 23.67). The value of clinical registries can be enhanced via data linkage, in this case by using PROMs to predict arthroplasty following femoral neck fracture.
