股骨逆行交锁髓内钉治疗股骨髁部C型骨折

目的探讨股骨逆行交锁髓内钉治疗股骨髁部C型骨折的方法和疗效。方法应用股骨逆行交锁髓内钉治疗股骨髁部C型骨折47例:C1型19例,C2型22例,C3型6例。结果47例随防6～48个月,平均20个月,骨折均愈合,平均愈合时间18周。根据Neer膝关节功能评分标准:优23例,良14例,可8例,差2例,优良率77.72%。结论股骨逆行交锁髓内钉是治疗股骨髁部C1、C2型骨折较理想手术方法,但对C3型骨折疗效欠满意。

The retrograde intramedullary nail in the treatment of type C fracture of surpracondylar femur

Objective To explore the methods and effects of surpracondylar femur type C fracture treated with retrograde intramedullary interlocking nail.Methods 47 acute surpracondylar femur fracture were treated with retrograde interlocking intramedullary nails.According to AO/ASIF classification system,there were 19 cases of type C1,22 type C2,6 type C3.47 cases were treated with open technique.Results The follow-up period ranged from 6 to 48 months,and the mean follow-up was 20 months.All fractures were healed,and the mean union time was 18 weeks.According to Neer's knee rating scale,the results were excellent in 23 cases,good in 14,fair in 8 and poor in 2,and the excellent and good rate was 77.72%.Conclusions It's an ideal method to treat surpracondylar femur fracture(type C1,C2)with retrograde interlocking intramedullary nail,but it is not as effective for type C3 fracture.
