【摘要】 目的探讨股骨近端防旋髓内钉(PFNA)与动力髋螺钉(DHS)两种手术方式治疗股骨转子间骨折的临床疗效。方法将79例股骨转子间骨折患者按治疗方法分为PFNA组(46例)和DHS组(33例)。对两组患者手术创伤、并发症及功能恢复情况进行比较。结果患者均获得随访,时间12~36个月。手术时间、术中出血量,术后卧床时间,骨折愈合时间PFNA组均优于DHS组,差异均有统计学意义(P<0.05)。髋关节功能评分两组比较差异无统计学意义(P>0.05)。结论 PFNA治疗股骨转子间骨折具有操作简单、骨折固定稳定、符合生物力学固定原则等优点。更多还原

【Abstract】 Objective To compare the outcome of proximal femoral nail antirotation( PFNA) and dynamic hip screw( DHS) in the treatment of femoral intertrochanteric fracture of the femur. Methods The patients with femoral intertrochanter fracture were randomly divided into PFNA group( n = 46) and DHS group( n = 33). The two groups were compared in aspect of general data. The clinical date of surgical trauma,complications and postoperative function of the two groups were compared. Results All patients were followed up ranged from 12 months to 36 months. Compared with DHS group,PFNA group had better outcome,there was statistically significant in the operation time,blood loss,postoperative time in bed and fractrue healing( P < 0. 05). There was no significant difference in the functional recovery of hip between two groups( P > 0. 05). Conclusions PFNA in the treatment of femoral intertrochanteric fracture fixation has advantages of simple manipulation,good function in fracture fixation,and being consistent with the biomechanics principle.更多还原
