Intramedullary supracondylar nail for supracon-dylar and intercondylar fractures of distal femur

目的 探讨股骨髁上逆向交锁髓内钉 (GSH钉 )治疗股骨远端骨折的价值。方法 应用GSH钉治疗新鲜股骨远端骨折 2 9例。结果 2 9例骨折均得到 7月至 3年 ,平均 17月的随访 ,平均愈合时间 14周 (8周至2 2周 )。采用NEER等膝关节功能评分标准 ,13例 (4 4 8% )优 ,11例 (37 9% )良 ,3例 (10 3% )可 ,优良率为82 8%。结论 GSH钉治疗股骨远端骨折 ,具有关节面解剖对位、生物学固定牢靠、术后允许早期功能锻炼等优点 。

Objective To explore the application value of supracondylar interlocking nail for supracondylar and intercondylar fractures of the distal femur. Method This series included 18 men and 11 women aged from 18 to 72 years. Supracondylar interlocking intramedullary nails were used in those who suffered from distal femur fractures with static technique,and CPM was followed.Result All patients were followed up for 7 months to 3 years (average followed up time 17 months). All were healed well with average healing time 14 weeks (ranged 8 to 22 weeks). The evaluation of the results by the Neer's criteria revealed good and excellent in 24 cases (82.8%), fair in 3 cases (10.3%) and poor in 2 cases (6.9%). No one got serious complications. Conclusion The supracondylar interlocking intramedullary nail is quite effective in the treatment of supracondylar and intercondylar femur fractures. The strong biomechanical fixation that provided by it is benefit to the healing of fractures and the recovery of motion of knee joints.
