目的 探讨应用股骨近端髓内钉( PFNA)治疗骨质疏松性股骨粗隆间骨折的临床疗效.方法 选取2010 年1 月~2016 年12 月本院收治的老年骨质疏松性股骨粗隆间骨折( Tronzo -Evens II~ IV型)患者97 例, 随机分为两组, 观察组50 例行 PFNA 固定、对照组47 例行动力髋螺钉( DHS)固定, 对两种方法的手术操作时间、手术切口长度、术中出血量、术后下床站立时间、骨折愈合时间、Harris评分和术后并发症进行统计学分析.结果 观察组手术操作时间、术中出血量、术后下床站立时间低于对照组, 术后Harris评分高于对照组, 均差异有统计学意义( P 0. 05) .结论 PFNA治疗骨质疏松性股骨粗隆间骨折, 具有易于术者操作、术中出血少、固定强度高、术后下床站立早等优点, 是治疗股骨粗隆间骨折的有效方法.“,”Objective To investigate the effect of proximal femoral nail antirotation (PFNA) in the treatment of osteoporot-ic intertrochanteric fractures. Methods From January 2012 to December 2016, a total of 97 cases with osteoporotic intertrochanteric fractures (Tronzo-Evens Ⅱ~Ⅳ) were randomly divided into two groups. The observation group (50 cases) was treated with PF-NA. The control group (47 cases) was treated with dynamic hip screw (DHS). The operation time, incision length, intraoperative bleeding, postoperative standing time, fracture healing time and Harris score were compared between two groups. Results The oper-ation time, intraoperative bleeding and postoperative standing time was less, and postoperative Harris score was higher in the observa-tion group than those in the control group (P0. 05). Conclusion PFNA fixation is an effective method for the treatment of osteoporotic in-tertrochanteric fractures of femur, which has advantages of simple operation, less blood loss, high fixation strength, and short postop-erative standing time.
