Abstract: Abstract    Objective   To compare the efficacy of percutaneous compression plate (PCCP) and dynamic hip screw (DHS) for intertrochanteric fractures of the aged. Methods   We searched the Cochrane Library, PubMed, EMbase, CNKI, Wanfang database and other databases. Retrieved the case-control study which used percutaneous compression plate and dynamic hip screw to treat intertrochanteric fractures of the aged, then compared the efficacy of percutaneous compression plate and dynamic hip screw for this kind of fractures by meta-analysis. Results   In 231 citations initially identified, 12 eligible papers, which included a total of 1159 patients followed up, met all the final criteria. We compared the operation duration, blood loss, wound healing, complications, fracture healing and functional outcome et al between PCCP and DHS. The results showed that the PCCP had a better outcome in the operation duration, blood loss, wound healing compared to the DHS, but it didn't show significant difference in the postoperative infection rate and mortality. Conclusions    The current analysis shows that the PCCP ( a quicker operation with minimal blood loss) is better in the older patients, but there should be more larger sample randomized controlled trials to provide decision-making evidence for clinical treatment of intertrochanteric fractures.
