Distal Locked versus Unlocked Intramedullary Nailing in Intertrochanteric Fracture; A Systematic Review and Meta-Analysis of Randomized and Non-Randomized Trials

Abstract

Background: Intertrochanteric fracture is the one of the most common fracture around hip. Intramedullary nailing is widely used for operative treatment of these fractures. The purpose of this meta-analysis is to assess the requirement of distal locking during intramedullary nailing of these fracturesMaterial and Methods: Randomized or non-randomized controlled studies comparing the effects of unlocked and locked nails were searched using the search strategy of Cochrane collaboration up to April 2019. Four eligible studies involving 691 patients were included. Their methodological quality was assessed, and data were extracted independently for meta-analysis.Results: The results showed that the unlocked group has significantly less Operative time MD -8.08, 95% CI -11.36 to -4.79, P< 0.00001, Fluoroscopy time MD -7.09, 95% CI -7.09 to -4.79, P
