逆行交锁髓内钉治疗股骨远端骨折疗效评价

目的 评价小切口复位逆行交锁髓内钉治疗股骨远端骨折的临床效果.方法 对24例股骨远端骨折采用小切口复位逆行交锁髓内钉内固定治疗的病例进行回顾性分析.按股骨远端骨折AO/ASIF分类,A型16例,C型8例.结果 本组病例随访时间6～24个月(平均17.4个月),平均愈合时间为4.6个月,无术后感染,1例远端锁钉断裂,经制动后骨折愈合.按Neer等膝关节评分标准进行评价,优15例,良6例,优良率87.5%.结论 小切口复位逆行交锁髓内钉治疗股骨远端骨折,手术操作简单,固定可靠,对软组织破坏少,骨折愈合率明显提高,用于治疗股骨远端复杂骨折手术效果好.

Retrograde femoral intramedullary interlocking nail fixation with small incision for distal femoral fracture

Objective To evaluate the efficacy of treatment of the distal femoral fracture with retrograde in-tramedullary interlocking nail with small incision. Methods Clinical data of 24 cases of distal femoral fracture trea-ted by retrograde intramedullary interlocking nail fixation with small incision, from July, 2004 to December, 2006 were retrospectively analyzed. According to AO/ASIF classification for distal femoral fracture , there were 16 be-longing to type A and 8 belonging to type C. Results 24 cases were followed up for 6 to 24 months, on average of 17.4 months. Average time for fracture union was 4.6 months. And no postoperative infection occurred. 1 case failed of treatment because of distal interlocking screw broken but healed by no weight- bearing. According to Neer criterion system, the percentage of good to excellent clinical result was 87.5 % (incuding excellent in 15 cases and good in 6 cases). Conclusion Retrograde intramedullary interlocking nail fixation with small incision is an ideal surgical treatment for distal femoral fracture, because of simple operation, rigid fixation and less soft tissue destruc-tion, which is good for bone healing of fracture.
