动力髋螺钉治疗股骨转子间骨折失效原因分析及处理

目的：探讨动力髋螺钉（dynamic hip screw,DHS）治疗股骨转子间骨折失效的原因及对策。方法：2007年6月至2009年12月共收的15例股骨转子间骨折DHS内固定失效患者,通过对术前、术后X线片进行回顾,分析其失效原因并给予对症处理,其中10例重新行切开复位DHS再次固定,5例行全髋关节置换。结果：本组15例随访0.50-1.83 a,平均1 a,根据髋关节功能Harris评分：优8例,良5例,中1例,差1例,优良率86.7%。结论：DHS内固定治疗股骨转子间骨折失效与术前适应证的选择及术中的操作技术有关,对于DHS内固定失效患者采取积极的再次手术治疗,术后可以获得较好的功能恢复和生活质量提高,疗效较满意。

The Reason and Cope of Dynamic Motivation Hip Screw in Treating Hip Screw Rotor Femoral Fracture Failure

Objective：To explore the dynamic motivation hip screw（hip screw rotor,while the femoral fracture failure treatment between the reasons and countermeasures.Methods：On June 2007 until 2009 on December 15 cases were gathered femoral fracture fixation DHS between rotor failure patients,through to the preoperative and postoperative X-ray are reviewed,analyzed its failure reason and give received alimta,including 10 routine to open reduction DHS again,5 underwent fixed total hip replacement.Results：Total 15 cases were followed up for 6 months-22 months,average 12 months,according to Harris hip score：optimal function in 8 cases,good in 5 cases,middle in 1 case,the difference in 1,dykes 86.7%.Conclusion：DHS internal fixation for femoral fracture failure between rotor with preoperative indications selection and art of operation for about technology,while the internal fixation failure patients take actively secondary surgery,and can obtain a good functional recovery and life quality improvement,curative effect is satisfactory.
