目的　分析股骨干骨折治疗失败的原因，探讨带锁髓内钉在翻修术中的应用疗效。　方法　29例股骨干骨折翻修手术，使用带锁髓内钉内固定，19例行自体髂骨植骨。　结果　全部病例经8~25个月随访，骨折愈合时间为5~12月，膝关节功能恢复良好，未出现感染、骨折不愈合或断钉等并发症。　结论　带锁髓内钉中轴弹性固定，手术创伤小、固定可靠、满足早期功能锻炼，是股骨干骨折特别是翻修术中较理想的内固定材料。

Objective　To analyze the reasons of the failure treatment on fracture of femoral shaft, and explore the effects of overhaul method by locking intramedullary nail.　Methods　29 patients suffered from the fracture of femoral shaft underwent revisional procedure, through the internal fixation of locking intramedullary nail, and then, 19 of them were given by self-iliac bone grafting.　Results　With 8-25 months' follow-up survey, all patients healed from the fracture during 5-12 months, accompanied with the well recovery of the functions of knee joint. There were no complications, such as infections, disunion of fracture or broken-nail happened.　Conclusions　Internal fixation with locking intramedullary nail is reliable for fracture fixation and functional recovery.  The locking intramedullary nail is one of ideal internal fixation materials especially in the revision for femoral shaft fracture.
