逆行交锁髓内钉结合松质骨螺钉治疗股骨髁间粉碎性骨折

Treatment of comminuted femoral intercondylar fracture with retrograde interlocking intramedullary nail and cancellous screw

目的总结逆行交锁髓内钉结合松质骨螺钉治疗股骨髁间粉碎性骨折的经验和疗效。方法对应用逆行交锁髓内钉结合松质骨螺钉治疗股骨髁间粉碎性骨折62例的临床资料进行回顾性分析。结果随访6～12个月，平均9个月。62例全部骨性愈合，骨折平均愈合时间4个月。根据Hohl膝关节功能评定标准评定：优52例，良8例；优良率96．8％。2例出现浅表感染，1例术后出现脂肪栓塞。结论股骨逆行交锁髓内钉结合松质骨螺钉能够提供坚强内固定，治疗股骨髁间粉碎性骨折有较高的临床应用价值。

Objective To summarize the effect of using retrograde interlocking intramedullary nail and cancellous screw in the treatment of comminuted femoral intercondylar fracture. Methods From May 2001 to August 2006,62 cases of the fresh comminuted femoral intercondylar fractures were treated with retrograde interlocking intramedullary nail and cancellous screw. Results Sixty-two cases were followed-up for 6-12 months（mean 9 months）. The bone healing was achieved in all patients. The average time of bone healing was 4 months. The functional scores on Hohl： 52 were excellent and 8 good,with an excellent and good rate of 96.8%. There were 2 cases of superficial infection and 1 case of fat embolism syndrome. Conclusion It is a good methed to use retrograde interlocking intramedullary nail and cancellous screw to treat the comminuted femoral intercondylar fracture. It can provide a stable and reliable fixation. It facilitates the fracture healing and functional recovery of the knee joint. The effect is excellent.
