【目的】探讨应用抗旋转型股骨近端髓内钉（proximal femoral nail antirotation ，PFNA）治疗股骨粗隆间骨折的疗效。【方法】2008年1月至2012年1月应用PFNA治疗股骨粗隆间骨折患者54例，术后随访并进行疗效评定。【结果】54例术后均获随访，随访时间为10～37个月，平均时间为13．8个月。所有患者骨折均获愈合，按髋关节功能Harris评分标准评定：优28例；良：21例；中：5例，优良率90．7％。【结论】PFNA手术操作简便、创伤小，固定牢靠，对血供影响小，是治疗股骨粗隆间骨折的良好方法。“,”[Objective] To explore the efficacy of proximal femoral nail antirotation(PFNA) for the treatment of intertrochanteric femoral fracture .[Methods]Totally 54 patients with intertrochanteric femoral fracture were treated with PFNA from Jan .2008 to Jan .2012 .All patients were followed up after operation .The efficacy was evaluated .[Results] All the patients were followed up after operation .The follow up time was for 10~37 months with 13 .8 months in average .The fractures of patients were all healed .According to Harris score standard ,28 patients were excellent ,and 21 patients were good ,and 5 patients were fair .The good and excellent rate was 90 .7% .[Conclusion] PFNA is simple operation ,minimal trauma ,stable fixation and little impact on blood sup-ply ,so it is good treatment of intertrochanteric femoral fracture .
