Cannulated Screws versus Dynamic Hip Screws for Treatment of Femoral Neck Fractures: A Systematic Review and Meta-Analysis

Abstract

The aim of this work is to provide cumulative data about the efficacy and safety of Cannulated Screws (CS) Vs Dynamic Hip Screw (DHS) for treatment of femoral neck fractures. Meta-analysis study was done on 17 studies which described and compared the 2 different techniques for femoral neck fractures; with overall number of patients (N= 54453). Regarding 1ry efficacy outcome measures, • We found 10 studies(28,29,32,1,35,38,39,40,41,31) reported union (success rate). The random-effects model of the meta-analysis study showed non-significant difference in union (success rate) in DHS group compared to CS group (p > 0.05). • We found 8 studies(33,35,39,42,1,40,29,31) reported Harris Hip score. The random-effects model of the meta-analysis study showed non-significant difference in mean Harris Hip score in DHS group compared to CS group (p > 0.05). • We found 9 studies(32,1,35,38,28,29,31,40,41) reported time of radiological union. The random-effects model of the meta-analysis study showed non-significant difference in mean time of radiological union in DHS group compared to CS group (p > 0.05).
