PFNA 与 DHS 内固定术治疗不稳定性股骨粗隆间骨折疗效分析

目的 临床分析骨近端防旋髓内钉（PFNA）与动力髋螺钉（DHS）内固定手术治疗不稳定性股骨粗隆间骨折的疗效.方法 选取我院2010-03～ 2013-03间收治的80例不稳定性股骨粗隆骨折患者,按照随机分配的方法将其分为PFNA组和DHS组,每组各40例,对每组患者的术中出血量、手术时间、术后卧床时间、骨折愈合时间进行回顾性分析,并对髋关节功能进行评分.结果 经过治疗后,给予12 ～24个月随访,平均14.7个月,两组患者的骨折愈合时间无明显差异.PFNA组患者术中出血量、术后卧床时间、手术时间均明显少于DHS组,两组对比存在显著性差异（P＜0.05）.对于髋关节评分,PFNA组显著高于DHS组,两组对比存在显著性差异（P＜0.05）.结论 针对不稳定性股骨粗隆间骨折患者,给予PFNA治疗,具有手术时间短、出血量少、术后恢复快等优点,值得临床推广应用.

Curative Effect Analysis of PFNA and DHS in the Treatment of Unstable Intertrochanteric Fractures

Objective To do clinical analysis of PFNA with DHS treatment of unstable intertrochanteric fractures. Methods From March, 2010 to March, 2013, 80 cases of unstable intertrochanteric fractures were treated, and according to the random allocation method they were divided into PFNA portfolio and DHS group. Each patient＇s blood loss, surgery time, bed time and fracture healing time were ret- rospectively analyzed, and hip function score was evaluated. Results After treatment, through 12 to 24 months follow - up and an average of 14. 7 months, the two groups had no significant difference in healing time. Blood loss, postoperative bed time, operative time in PFNA group were significantly less than the DHS group. There was significant difference in the two groups （P 〈 0.05）. For hip score, PFNA group was significantly higher than the DHS group. There was significant difference between the two groups （P 〈 0. 05 ）. Conclusion For the instability of intertrochanteric fractures, patients were given PFNA treatment, with a shorter operative time, less bleeding and rapid post- operative recovery, etc. It is worthy of clinical application.
