Abstract
BackgroundThe aim of this meta-analysis was to compare the outcomes of proximal femoral nail (PFN) and dynamic hip screw (DHS) in treatment of intertrochanteric fractures.Material/MethodsRelevant randomized or quasi-randomized controlled studies comparing the effects of PFN and DHS were searched for following the requirements of the Cochrane Library Handbook. Six eligible studies involving 669 fractures were included. Their methodological quality was assessed and data were extracted independently for meta-analysis.ResultsThe results showed that the PFN group had significantly less operative time (WMD: −21.15, 95% CI: −34.91 – −7.39, P=0.003), intraoperative blood loss (WMD: −139.81, 95% CI: −210.39 – −69.22, P=0.0001), and length of incision (WMD: −6.97, 95% CI: −9.19 – −4.74, P<0.00001) than the DHS group. No significant differences were found between the 2 groups regarding postoperative infection rate, lag screw cut-out rate, or reoperation rate.ConclusionsThe current evidence indicates that PFN may be a better choice than DHS in the treatment of intertrochanteric fractures.
