改良动力髋治疗股骨粗隆间粉碎性骨折35例

Analysis of Improved Dynamic Hip Screw(DHS) for the treatmeant of femoral intertrochanteric fractures in 35 cases

目的探讨用改良动力髋钢板固定，延期动力化治疗股骨粗隆间粉碎性骨折的疗效。方法采用改良动力髋钢板治疗股骨粗隆间粉碎性骨折35例。结果本组病例随访12-24月，平均15．2个月，骨折均愈合，患髋功能恢复良好。结论采用改良动力髋钢板内固定治疗股骨粗隆间粉碎性骨折的方法疗效肯定，可预防术后主钉松动，骨折延迟愈合、髋内翻、股骨颈短缩等并发症的发生。

Objective To evaluate the effects of improved dynamic hip screw delayed dynamic on femoral intertrochanteric fractures. Methods 35 cases in femoral intertrochanteric fracture were treated with improved dynamic hip screw delayed dynamic. Results The follow-up period were 12-24 months, with average of 15.2 months. And all 35cases were recovery without fracture delayed union and non-union. Conclusion Treatment of femoral intertrochanteric fractures with improved dynamic hip screw is effective. It is an operative measure to prevent postoperative main nail instability, fracture delayed union, coxa vara, femoral neck reduction, and other complications.
