摘　　要：目的:探讨空心拉力螺钉治疗Hoffa骨折的手术方法及临床疗效。方法:2001年2月至2009年5月采用空心拉力螺钉治疗Hoffa骨折13例,男8例,女5例;年龄23～45岁,平均34.2岁;左侧6例,右侧7例。按Letenneur分型:股骨外髁,Ⅰ型3例,Ⅲ型2例;股骨内髁,Ⅰ型3例,Ⅱ型2例,Ⅲ型3例。根据骨折类型,按不同入路应用松质骨空心拉力螺钉内固定治疗。结果:13例均获随访,时间12～23个月,平均16.5个月。所有患者未发现腘窝动脉、胫神经或腓总神经等并发症。术后半年根据Letenneur膝关节功能评分,优10例,可3例。术后半年X线片示骨折骨性愈合,未发现空心螺纹钉松动、断裂及骨折不愈合等。结论:空心拉力螺钉治疗Hoffa骨折临床疗效满意,手术入路及内固定方式应根据骨折类型、骨折线的位置及骨折块的大小等因素综合判断。Objective：To investigate the operation techniques and clinical effects of hollow lag screws for the treatment of Hoffa fractures. Methods：From February 2001 to May 2009,13 patients with Hoffa fractures were treated with hollow lag screws,including 8 males and 5 females,ranging in age from 23 to 45 years,with a mean age of 34.2 years. Six patients had the fractures on the left,7 patients on the right. According to the Letenneuer type,femur lateral condyle：typeⅠin 3 cases,typeⅢin 2 cases;femur medial condyle：typeⅠin 3 cases,typeⅡin 2 cases,typeⅢin 3 cases. According to the type of fracture,hollow lag screws were used to treat the fracture with different approach. Results：All the patients were followed up,and the duration ranged from 12 to 23 months,with a mean of 16.5 months. All the patients had no complications such as popliteal artery,tibial nerve or peroneal nerve injuries. According to Letenneur knee function score：10 patients got an excellent result,3 good. At the half year after operation,the X-ray showed all the fractures had bone union. There were no hollow lag screw loosening,broken or nonunion. Conclusion：The clinical effect of hollow lag screw for the treatment of Hoffa fractures is satisfactory. The surgical approach and fixation should be determined by the type of fracture,the location of the fracture line and the size of fracture fragments.
