PFNA及DHS内固定术治疗老年不稳定型股骨粗隆间骨折的效果对比

Effects comparison of PFNA and DHS in the treatment of elderly unstable intertrochanteric fractures

目的:探讨股骨近端防旋髓内钉(PFNA)和动力髋螺钉(DHS)内固定术治疗老年不稳定型股骨粗隆间骨折的效果。方法:选取64例不稳定型股骨粗隆间骨折患者为研究对象,根据手术方式不同分为A组(n=36)和B组(n=28)。A组患者采用PFNA手术治疗;B组采用DHS手术治疗。比较两组患者术中(手术时间、切口长度、出血量)和术后(住院时间、骨折愈合时间、并发症发生率)相关指标及术后6个月髋关节功能恢复情况。结果:A组患者手术时间、切口长度、出血量、骨折愈合时间、并发症发生率均低于B组(P<0.05);两组患者住院时间比较,差异无统计学意义(P>0.05)。术后6个月,A组患者髋关节功能优良率高于B组(P<0.05)。结论:PFNA和DHS对治疗老年不稳定型股骨粗隆间骨折均有效,但PFNA治疗效果更好,并发症少,值得临床应用。

Objective:To compare the effects of proximal femoral anti-rotation intertrochanteric nail(PFNA)and dynamic hip screw(DHS)in the treatment of elderly unstable intertrochanteric fracture.Methods:A total of 64 elderly patients with unstable intertrochanteric fracture of femur were selected and 36 patients treated with PFNA surgery were regarded as group A,and 28 patients treated with DHS surgery were regarded as group B.The related indexes intraoperative(operation time,incision length,intraoperative blood loss)and postoperative(hospital stay,fracture healing time,incidence of complications)and the recovery of hip joint function 6 months after operation were compared between the two groups.Results:The operation time,incision length,intraoperative blood loss,fracture healing time,and incidence of complications of group A were significantly lower than those of the group B(P<0.05).There was no significant difference in hospital stay between the two groups(P>0.05).The good rate of hip joint function in group A was significantly higher than that in the group B(P<0.05).Conclusion:PFNA and DHS are effective in the treatment of elderly patients with unstable intertrochanteric fracture,but PFNA has better effect and fewer complications,which is worthy of clinical application.
