Do We Really Need to Repair the Pronator Quadratus in Volar Plating of Distal Radius Fracture？A Protocol for Systematic Review and Meta Analysis

Abstract

IntroductionDistal radius fracture is a common type of fracture in clinical practice.Over recent years, Volar locking plate internal fixation remains the most commonly used surgical treatment method in the treatment of distal radius fractures. To better expose the distal radius and fracture segment, the surgeons have to cut the pronator quadratus(PQ) muscle.However, whether the PQ muscle need to be repaired remains controversial. This study aims to provide a plan to evaluate the clinical efficacy whether to repair the PQ muscle in volar plate fixation of distal radius fractures.Methods and analysisWe will search PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI),and Wanfang databases from the beginning to February 2021 to compare clinical outcomes whether to repair the PQ muscle. Quality assessment will be evaluated using the risk of bias tool recommended by the Cochrane Handbook 5.2.0. Subsequently, Revman software version 5.3 will be used for data analysis when a meta-analysis is allowed including subgroup and sensitivity analysis.PROSPERO registration number CRD42020206959
