目的：评价防旋转股骨近端髓内针治疗股骨粗隆间不稳定骨折的临床疗效。方法：对使用PFNA内固定治疗的22例股骨
粗隆间骨折的分类、手术方法、术后结果进行疗效分析。结果：所有患者均进行11~26个月的随访，平均随访时间13个月。骨折全部临床愈合。按关节评分：优16例，占73%，良4例，占18%，可2例，占9%，优良率90.9%。结论：PFNA治疗老年股骨粗隆间不稳定骨折，具有手术操作简单、创伤小、固定可靠的特点，是内固定治疗股骨粗隆间不稳定骨折的比较理想方法。
Objective: To evaluate proximal femoral nail anti-rotation（PFNA）in the treatment of unstable intertrochanteric fracture.
Methods: The classifications, operation approachs and post-operative effects were assessed in the 22 patients of intertrochanter fracture of femur treated with PFNA. Results: All cases were followed up from 11 to 26 months after operations（average 13 months）.The post-operative follow-up study showed that all the cases were fracture healed, under the joint scores, 16 cases were excellent （73%）, 4 cases were good （18%）, 2 cases were normal （9%）, the excellent rate was 90.9%. Conclusion: Treatment of elderly unstable intertrochanteric fracture of with PFNA was an ideal approach with simple operation, less trauma, reliable fixation.
