Efficacy of four hollow nail rhombic fixation for the treatment of patients with femoral neck fractures: A protocol of systematic review and meta-analysis

Background: This study aims to assess the efficacy of four hollow nail rhombic fixation (FHNRF) for the treatment of patients with femoral neck fractures (FNF). Methods : A literature search in MEDLINE, Scopus, Web of Science, EMBASE, Cochrane Library, ProQuest, Thesis and Dissertation Catalog, Cumulative Index to Nursing and Allied Health Literature, and China National Knowledge In­frastructure will be performed from inception through February 29, 2020. This study will not apply limitations to the language and publication date. All potential randomized controlled trials (RCTs) that identify the efficacy and safety of FHNRF for the treatment of patients with FNF. Two contributors will separately examine searched records, extract essential data, and assess study quality using Cochrane risk of bias tool. Any opposition between two authors will be settled by a third contributor. We will employ RevMan 5.3 software for statistical analysis. Discussion : This study will summarize high quality RCTs to assess the efficacy and safety of FHNRF for the treatment of patients with FNF. It will help to determine whether or not FHNRF is effective and safety for the treatment of patients with FNF. Systematic review registration CRD42020168378.
