     摘要：[目的]评价逆行交锁髓内钉(RIIN)内固定治疗狭部以远股骨干骨折的临床疗效。[方法]对1999年10月~2005年1月使用RIIN治疗37例(39肢)狭部以远股骨干骨折的疗效进行回顾性分析，其中开放性骨折8肢，闭合性骨折31例，均行静力固定。[结果]随诊8~24个月，平均15个月。发生浅表感染2肢。39肢均达骨性愈合，骨折愈合时间9~20周，平均15周。无深部感染、畸形愈合、主钉及锁钉断裂等并发症发生。Merchan功能评定优良率949%。[结论]RIIN内固定治疗狭部以远股骨干骨折具有良好的生物力学性能，骨折愈合率高且并发症少，严格操作规程和术后早期积极功能锻炼是治疗成功的关键。

    Abstract：[Objective]To evaluate the clinical effects of retrograde interlocking intramedullary nail(RIIN) for internal fixation of the femoral shaft fractures distal to the isthmian[Method]Thirtyseven cases (39 limbs) of femoral shaft fractures distal to the isthmian were treated with RIIN from October 1999 to January 2005. Their outcomes were reviewed retrospectively. There were 8 limbs of open fracture and 31 limbs of close fractureAll fractures were fixed statically[Result]All patients were followed up for 8~24 months, with the average time of 15 monthsTwo limbs suffered suoerficical infection, all limbs had bony union within 9~20 weeks, with the average time of bone union of 15 weeks No deep part infection, malunion and nail failure were observedThe rate of being excellence with Merchan evaluation was 974%[Conclusion]Internal fixation with RIIN for femoral shaft ftractures distal to the isthmian can demonstrating good biomechanic property lead to high union rate of fraeture with less complications The technique of RIIN must be performed strictly during operation and early active functional rehabilitation is the key to obtain good isthmion clinical result ......
