No advantages of Gamma nail over sliding hip screw in the management of peritrochanteric hip fractures: a meta-analysis of randomized controlled trials.
OBJECTIVE
There is a lack of consensus regarding the best option for the operative treatment of peritrochanteric fractures. A meta-analysis was performed to assess the surgical outcomes of peritrochanteric fractures.


METHODS
Only prospective, randomized studies comparing Gamma nail and sliding hip screw (SHS) fixation in adults were included. Eleven studies met the inclusion criteria: the target population consisted of patients with peritrochanteric fractures, while subtrochanteric fractures were not included; the intervention was SHS compared with Gamma nail; the study was a published randomized trial. Each outcome measure tested was assessed for heterogeneity. If significant heterogeneity was present, data from the studies were not combined. If there was no significant heterogeneity, a combined relative risk was calculated using a fixed effects model and a Z-test was performed to test the overall effect.


RESULTS
A total of 1344 peritrochanteric fractures entered into the included studies. There were no differences of mortality, cut-out, non-union, re-operation, wound infection, intra-operative fractures of femur, blood loss or surgical time.


CONCLUSIONS
It seemed that there were no obvious advantages of Gamma nail fixation over SHS fixation in treating peritrochanteric fractures.
