Clinical Results or Treatment for Distal Femur Fractures with Close Reduction and Retrograde Intramedullery Interlocking Nails

目的:总结临床应用闭合复位逆行交锁髓内钉治疗股骨下段骨折的经验。方法:应用闭合复位自髌韧带处纵形小切口经股骨髁间窝前方插钉行逆行交锁髓内钉内固定治疗股骨下段骨折38例。结果:38例股骨下段骨折全部骨性愈合。骨折愈合的时间平均11周。根据Lysholm膝关功能评分标准[1]进行疗效评定,结果优30例,良6例,一般2例,差0例。优良率为94%。结论:闭合复位逆行交锁髓内钉治疗股骨下段骨折更利于骨折的愈合和膝关节功能的恢复。

Objective： To explore the clinical application and the optium opertion manners of retrograde interlocking intramedullery nail in treating distal femur fractures. Method： Thirty-eight,cases of distal femur fractures treated with retrograde intramedullery interlocking nails by using close reduction and nailing it in front of fossa intercondylaris through ligament patellar incision were reviewed. Result： All of 38 cases achieved clinical bone healing by using the times which are 11 weeks on average. The results therapy were excellent in 30, good in 6, fair in 2, poor in 0 according to the Lysholm criteria . The “good”or “excellent” rate is 94%. Conclusion ： Use of close reduction and retrograde intramedullery interlocking nails has not only adantages of bone healing but also benefiting the recovery of knee joint functions.
