逆行有限扩髓交锁髓内钉治疗股骨骨折

目的 分析逆行有限扩髓交锁髓内钉治疗股骨干骨折的临床效果。方法 1999年6月～2003年9月应用逆行有限扩髓交锁髓内钉治疗股骨干骨折74例，男62例，女12例。择期手术72例，急诊手术2例。按A0分型：32A1型5例，32A2型7例，32A3型12例，3282型35例，32C2型15例。结果 74例均获随访13～29个月，平均15．4个月，骨折均愈合，愈合时间3～5个月，平均3．8个月。按照吴岳嵩疗效结果评定标准，优60例，良13例，优良率98．7％。骨折不愈合1例，迟发性感染1例，锁钉弯曲2例。结论 逆行有限扩髓交锁髓内钉治疗股骨骨折，手术操作简便，对局部血运破坏少，有利于骨折愈合，可早期行功能锻炼。

TREATMENT ON FEMORAL FRACTURES WITH INVERSE LIMITED MARROW CAVITY RASPING INTRAMEDULLARY INTERLOCKING NAIL

Objective To evaluate the results of the treatment on femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail . Methods From Jun. 1999 to Sep. 2003, 74 patients with femoral fractures were treated by intramedullary interlocking nail (inverse limited marrow cavity rasping) .There were 62 males and 12 females. Among them, 5 cases were type 32A1, 7 cases were type 32A2, 12 cases were type 32A3, 35 cases were type 32B2, and 15 cases were type 32C2. Results Seventy four patients were followed up for 13 to 29 months(15.4 months in average). The time for fracture union ranged from 3 to 5 months(3.8 months in average). The overall rate of excellence was 98.7% by Wuyuesong grading. There was 1 case of non union, 1 case of delayed infection, and 2 cases of bent screw. Conclusion The treatment on femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail is easy to operate and has minimum impairment to local circulation. It also promotes the healing and early function.
