股骨近端防旋髓内钉治疗老年骨质疏松性粗隆间骨折的疗效观察

目的探讨应用股骨近端防旋髓内钉（proximal femoral nail anti—rotation，PFNA）治疗股骨粗隆间骨折的疗效。方法12例股骨粗隆间骨折应用PFNA进行治疗。结果经6～24个月随访，平均12个月，骨折全部获得愈合。根据Harris髋关节评分为优9例，良2例，差1例，优良率为91．7％。结论PFNA治疗股骨粗隆间骨折具有创伤小、固定牢靠、防旋转、防切割等优点，是治疗股骨粗隆间骨折理想的内固定物，值得推广。

Clinical analysis of the treatment of femoral intertrochanteric fracture with proximal femoral nail anti-rotation

Objective To evaluate the clinical effects in the treatment of femoral intertrochanteric fracture with proximal femoral nail Anti-rotation（PFNA）. Methods In a prospective study 12 patients with proximal femoral fractures were treated with PFNA. Results 12 patients were followed up for 6 - 24 months （ with an average of 12 months ）. All fractures were healed. According to Harris criterion, the excellent results in 9 patients, good results in 2 patients and poor results in 1 patient were obtained. The excellent and good rate of the function of the hip joint was 91.7%. Conclusion PFNA has the advantages of less surgical trauma,stable fixation, anti-rotation and anti-cutout. So it is a useful device in the treatment of femoral intertrochanteric fracture.
