摘要
目的评估股骨近端髓内钉PFN—A治疗不稳定股骨粗隆间骨折的临床疗效。方法2007～2009年42例不稳定股骨粗隆间骨折患者按AO分类，31-A2型23例，31～A3型19例。使用PFN-A治疗，统计术中失血量，手术时间．骨折愈合时间．髋关节功能评价。结果本组患者术中平均失血量小于100ml，平均手术时间1h。术后随访6～24个月，全部骨折均愈合．除1例在术后2个月出现髓内钉远端的股骨干骨折，80％的患者在术后六个月恢复术前的患髋关节功能，无股骨头缺血坏死及髋内翻畸形。结论股骨近端髓内针PFN—A治疗股骨粗隆间骨折具有手术简单、固定牢稳、微创、并发症少的特点，尤其适用于骨质疏松的老年患者，是目前治疗不稳定型股骨粗隆间骨折较为合适的治疗方法。
Objective To evaluate the therapeutic effect of proximal femoral nail-A （PFN-A） in unstable femoral intertrochanteric fractures. Methods From 2007 to 2009, 42 patients with unstable trochanteric fractures （AO/ASIF classification： 31.A.2 and A.3 only） were treated with PFN-A instrumentation by means of closed reduction and fixation. Blood loss, operation time, fracture healing and functional re- covery of the hip joints were observed. Results The mean blood loss was less than 100 ml and the mean operation time was 60 min, fol- low-up from 6 to 24 months after operation showed union of fracture in all cases. Only a case of periprosthetic femoral fractures was found 2 months after operation because of slipping accident. Eighty percent of the patients regained the pre-trauma mobility. No case of ischemia and necrosis of femoral head, malformation of hip and hip varus were observed. Conclusion The clinical treatment of unstable femoral in- tertrochanteric fractures with PFN-A is convenient, stable, mini invasive and almost free from complications, which is applicable to patients ofosteoporosis. PFN-A may be the more appropriate instrumentation for treatment of unstable femoral intertrochanteric fractures.
