21例股骨远端骨折的治疗分析

Treatment of the Fracture of the Lower Segment of Femur:A Report of 21 Cases

目的：根据股骨远端的解剖功能特点，作者采用双矩形钉固定治疗股骨远端骨折。方法：自股骨内外髁逆行向股骨近端插入２根矩形钉。钉在髓腔内呈“Ｘ”型固定，其稳定性好。插钉时必须保持２钉在同一平面。术后长腿石膏托制动２周。效果：骨愈合平均１４．５周，下床负重活动平均２１．５ｄ。所有病人功能恢复良好。均恢复原工作和生活。无并发症。结论：生物力学试验表明固定器稳定性好。能早期行膝关节和肢体功能锻炼。本法设备操作简单，易推广应用。

According to the anatomy and function of the supracandyle of femur,we applied two rectangle sloped flexsegment nail for femoral bone fracture.The two nails were inserted in the lower segment of femur in the same level,from internal and external sides of supracondyle.They were stable and look like “X”in the medullary channel.The long plaster splints were applied for 2 weeks postoperatively.The fractures united after 14.5 weeks,the functions recovered excellently without complication.The biomechanic test reveals that the fixator has a high stability and the knee joint could move freely.This procedure is simple and easy to be popularized.
