ABSTRACT
Objective To compare the efficacy of percutaneous compression plate (PCCP) and dynamic hip screw (DHS) on intertrochanteric fractures in elderly patients. Methods A literature search was performed in the Cochrane Li-brary, Mdiline, EMbase, CNKI, Wanfang database and other databases. The controlled clinical trials were retrieved, which in-cluded PCCP and DHS treatment for intertrochanteric fractures in elderly patients. A meta-analysis was performed to ana-lyze the efficacy of PCCP and DHS on this kind of fractures in elderly patients. Results In 231 citations initially identified, 11 eligible papers were included in this study, which consisted of a total of 1 100 patients. Results showed that there were shorter operative time (WMD=-12.83,Z=2.54,P=0.01), smaller incision(WMD=-7.43,Z=3.35,P＜0.001), low blood loss during surgery(WMD =-211.41,Z=9.07,P＜ 0.001) and better prognosis in PCCP group than those of DHS group. There was no significant difference in the length of postoperative hospital stay between PCCP and DHS group(WMD=-1.28, Z=0.89, P=0.37). Conclusion The current analysis suggests that the PCCP is better for intertrochanteric fractures in elderly patients.
