Comparative Study between Dual Mobility Total Hip Replacement versus Bipolar Hemiarthroplasty in the Treatment of Displaced Femoral Neck Fractures in the Elderly

Abstract Background Total hip arthroplasty (THA) or hemiarthroplasty are the most popular treatments for dislocated intracapsular hip fractures. Objective to compare dual mobility total hip arthroplasty and bipolar hemiarthroplasty as a management for the femoral neck fracture in elderly and evaluating the functional outcome. The objective is to perform a systematic review of the outcomes of use of the dual mobility total hip arthroplasty compared to bipolar hemiarthroplasty. Patients and Methods We included randomized controlled trials, including cluster RCTs, controlled (non-randomized) clinical trials or cluster trials, prospective and retrospective comparative cohort studies and case control or nested case-control studies. Results There was statistically significant decrease in the Harris Hip score in BA group (78.31±9.25) than THA group (82.72±7.53). There was statistically significant increase in the percentage of patients with dislocation in BA group (6.2%) than THA group (1.9%). Data Sources Medline databases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available in the Internet till 2023. Conclusion dual mobility cup total hip arthroplasty offers for the patients many advantages such as stability, lower dislocation rates and longevity, all those pros make it a superior treatment choice that bipolar hemiarthroplasty.
