【 摘 要 】

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 nonrandomized trials indicate that better-designed randomized controlled trials will be required.
