InterTan nail versus Gamma3 nail for intramedullary nailing of unstable trochanteric fractures
Background Trochanteric fractures ( TF ) have become a major source of morbidity and mortality in elderly . We conducted this study to compare the outcomes of unstable trochanteric fractures treated with the InterTan nail and Gamma3 nail . Methods Between January 2008 and May 2013 , patients aged 60 years or older with a diagnosis of unstable TF treated with InterTan nail or Gamma3 nail were included . Patients treated with InterTan nail were pair-matched to patients treated with Gamma3 nail in a 1:2 ratio . Radiographs were obtained at 1 , 3 , 6 , and 12 months follow-up , and all implant position changes , complications , fixation failures and functional scores were recorded . Results Eighty-seven patients were included in the InterTan nail group , and 174 pair-matched patients were included in the Gamma3 nail group . Preoperative scores were similar between the 2 groups . There are significant improvements postoperatively in both groups . The incidence of cut-out and femoral shaft fracture were significantly higher in the Gamma3 nail group than the InterTan nail group ( P = 0.024 and P = 0.044 , respectively ) . Patients treated with the InterTan nail experienced longer fluoroscopy and operative times . Conclusions The InterTan nail may have a tendency in better outcomes for patients with unstable TF . However , the limited period of follow-up and inherent defects of nonr and omized trials indicate that better- design ed r and omized controlled trials will be required .
