股骨近端防旋髓内钉和动力髋螺钉内固定治疗老年股骨粗隆间骨折的临床疗效

Effect of proximal femoral nail antirotation and dynamic hip screw internal fixation in elderly intertrochanteric fractures

目的探讨股骨近端防旋髓内钉(PFNA)与动力髋螺钉(DHS)内固定治疗老年股骨粗隆间骨折的临床疗效。方法将56例老年粗隆间骨折患者根据治疗方式不同分为两组,每组28例。A组采用PFNA内固定治疗,B组采用DHS内固定治疗。对比两组患者的治疗效果。结果两组治疗优良率比较差异无统计学意义(P>0.05)。A组手术时间、术中出血量、术后下地活动时间、骨折愈合时间、并发症总发生率均优于B组(P<0.05)。结论两种内固定治疗老年粗隆间骨折均具有较好疗效,但PFNA内固定能减少损伤,缩短骨折愈合时间,减少术后并发症发生率,安全性更高。

Objective To discuss the clinical curative effect of proximal femoral nail antirotation（PFNA） and dynamic hip screw（DHS） internal fixation in elderly intertrochanteric fractures. Methods Fifty-six cases of senile intertrochanteric fractures were divided into two groups according to different treatment methods, with 28 cases in each group. The group A was treated with PFNA internal fixation, the group B was treated with DHS internal fixation. The treatment effects of the two groups were compared. Results There was no significant difference in the excellent and good rate of treatment between the two groups（P 〉0.05）. The operation time, the amount of intraoperative bleeding, postoperative activity time, fracture healing time and total incidence of complications in the group A were better than those in the group B（P〈 0.05）.Conclusion Two kinds of internal fixation methods in the treatment of senile intertrochanteric fractures have good curative effect, but PFNA internal fixation can reduce injury, shorten fracture healing time, reduce the incidence of postoperative complications, with higher security.
