Purpose Unipolar and bipolar hemiarthroplasty (HA) are used to treat displaced femoral-neck fractures. However, which type is best for treating displaced femoral-neck fractures in elderly patients remains a subject for debate. Our aim was to review randomised controlled trials to establish which type provides superior clinical outcome for this patient population. Methods We searched PubMed, Embase and Cochrane Register of Controlled Trials databases and Web of Science for randomised controlled trials (RCTs) comparing unipolar with bipolar HA to treat femoral-neck fracture in the elderly. Risk ratios (RRs) and mean differences (MDs) from each trial were pooled using random-effects or fixed-effects models depending on study heterogeneity. Analysis was performed using RevMan5.2 from the Cochrane Collaboration. Results A total of 1,100 patients from nine studies were assessed in this meta-analysis. Results showed no significant differences in function score [MD=−0.14, 95% confidence interval (CI) −2.42-2.13], mortality (RR=0.97, 95% CI 0.65-1.46), dislocation (RR=1.33, 95 % CI 0.53-3.34), deep infection (RR=0.79, 95 % CI 0.35-1.79), acetabular erosion (RR=1.99, 95 % CI 0.61-6.52), operating time (MD=2.14, 95 % CI −9.85 to14.14), blood loss (MD=13.40, 95 % CI −49.60 to 76.39) and length of hospital stay (MD=0.12, 95 % CI −0.49to0.73) between unipolar and bipolar HA. Conclusions Unipolar and bipolar HA achieved similar clinical outcomes in patients with displaced femoral-neck fractures.

“…The bipolar hemiarthroplasty has been used to treat displaced femoral neck fractures in older patients, and it has been reported to provide patients with pain relief, functional improvement, and low revision rate [10,21]. Dislocation and dissociation are relatively uncommon but devastating complications.…”

Background Hip dislocation after treatment of a femoral neck fracture with a hemiarthroplasty remains an important problem in the treatment of hip fractures, but the associations between patient factors and surgical factors, and how these factors contribute to dislocation in patients who have undergone bipolar hemiarthroplasty through an anterolateral approach for femoral neck fracture currently are only poorly characterized. Questions/purposes We evaluated patients with bipolar hemiarthroplasty dislocation after surgery for femoral neck fracture treated through an anterolateral approach and asked: (1) What are the frequency, characteristics, and risk factors of bipolar hemiarthroplasty dislocations? (2) What are the frequency, characteristics, and risk factors of bipolar hemiarthroplasty dissociations?

BackgroundHip fractures are a major healthcare problem, presenting a major challenge and burden to patients and healthcare systems. The number of hip fractures globally is rising rapidly. The majority of intracapsular hip fractures are treated surgically. ObjectivesTo assess the relative effects (benefits and harms) of all surgical treatments used in the management of intracapsular hip fractures in older adults, using a network meta-analysis of randomised trials, and to generate a hierarchy of interventions according to their outcomes. Search methodsWe searched CENTRAL, MEDLINE, Embase, Web of Science, and five other databases in July 2020. We also searched clinical trials databases, conference proceedings, reference lists of retrieved articles and conducted backward-citation searches. Selection criteriaWe included randomised controlled trials (RCTs) and quasi-RCTs comparing different treatments for fragility intracapsular hip fractures in older adults. We included total hip arthoplasties (THAs), hemiarthroplasties (HAs), internal fixation, and non-operative treatments. We excluded studies of patients with specific pathologies other than osteoporosis or resulting from high energy trauma. Data collection and analysisTwo review authors independently assessed studies for inclusion. One review author completed data extraction which was checked by a second. We collected data for three outcomes at different time points: mortality and health-related quality of life (HRQoL) -both reported within 4 months, at 12 months, and after 24 months of surgery, and unplanned return to theatre (at end of study follow-up).We performed a network meta-analysis (NMA) with STATA software, using frequentist methods, and calculated the differences between treatments using risk ratios (RRs) and standardised mean differences (SMDs) and their corresponding 95% confidence intervals (CIs). We also performed direct comparisons using the same codes. Main resultsWe included 119 studies (102 RCTS, 17 quasi-RCTs) with 17,653 participants with 17669 intracapsular fractures in the review; 83% fractures were displaced. The mean participant age ranged from 60 to 87 years and 73% were women.
