To evaluate the results of the treatment on femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail.
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.
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.
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.
评估采用逆向有限扩髓带锁髓内钉治疗股骨骨折的效果。
1999年6月至2003年9月，74例股骨骨折患者接受了带锁髓内钉（逆向有限扩髓）治疗。其中男性62例，女性12例。其中，32A1型5例，32A2型7例，32A3型12例，32B2型35例，32C2型15例。
74例患者随访13至29个月（平均15.4个月）。骨折愈合时间为3至5个月（平均3.8个月）。根据吴岳嵩评分，优良率总体为98.7%。出现1例骨不连、1例延迟感染和2例螺钉弯曲。
采用逆向有限扩髓带锁髓内钉治疗股骨骨折操作简便，对局部血运破坏最小，能促进骨折愈合及早期功能恢复。
