Introduction

Hip arthroplasties for the treatment of displaced femoral neck fractures in adults can be total replacement or hemiarthroplasty. Despite the high prevalence of these fractures and large number of studies on the topic, the best choice of arthroplasty to be used remains unclear. The present study aims to overview the results of systematic reviews of randomised controlled trials (RCTs) comparing outcomes between total hip replacement and hemiarthroplasty for displaced femoral neck fractures in adults.

Methods and analysis

Four electronic databases (Pubmed, Embase, Cochrane Library and Web of Science) and reference lists from previous reviews will be searched without language limitation. Eligible studies will be systematic reviews of RCT that compare total hip replacement and hemiarthroplasty for treatment of displaced femoral neck fractures in adults. Two reviewers will independently perform study selection, data extraction and quality assessment. Disagreements between reviewers will be resolved by a third reviewer. Comparisons of dichotomous data will report as the OR and 95% CI, and comparisons of functional and health-related quality of life outcomes are reported as the mean difference and 95% CI and as the risk difference, defined as the difference in the proportion achieving the minimum clinically important difference and 95% CI. As this overview will contribute to orthopaedic surgeons and health managers in better decision-making for the treatment of these fractures. The authors plan to complete the searches and analyses by 30 November 2021.

Ethics and dissemination

Ethical approval was obtained at Federal University of Sao Paulo. Findings will be disseminated through peer-reviewed publication.
