目的：对动力髋螺钉（dynamic hip screw，DHS）内固定和防旋型股骨近端髓内钉（proximal femoral nail an-tirotation，PFNA）内固定治疗股骨粗隆间骨折的疗效及术后并发症进行对比研究。方法对107例股骨粗隆间骨折患者分别给予DHS和PFNA内固定术，并对患者的骨折类型、术后并发症和总体疗效进行比较。结果两组随访平均28个月（24～36个月）。 DHS组术后并发症总发生率显著高于PFNA组，差异具有统计学意义（P＜0．05）。结论对于股骨粗隆间骨折的患者，PFNA内固定术具有更好的疗效和更少的术后并发症，但仍需依据骨折类型、骨质疏松情况及内固定生物力学特点选择术式，重视患者术后功能康复锻炼。

Objective To compare DHS(dynamic hip screw )with PFNA(proximal femoral nail antirotation) treatment for intertrochanteric fractures and to analyze their postoperative complications .Methods A total of 107 patients with inter-trochanteric fractures were treated with DHS and PFNA fixation respectively .The type of fracture , postoperative complica-tions and overall efficacy were compared .Results After the follow-up of 28(24 to 36) months.DHS group had a higher overall incidence of postoperative complications than the PFNA group and the difference was statistically significant ( P<0.05).Conclusion In order to reduce the intertrochanteric fracture fixation complications , the type of fracture, osteoporo-sis and biomechanical fixation characteristics need to be considered when selecting surgical procedures .Postoperative func-tional rehabilitation is to be improved .The curative effect of PFNA is better than that of DHS .
