股骨颈骨折后股骨头缺血坏死

Ischemic Necrosis of Femoral Head after Femoral Neck Fracture

报告一组获得随访的438例股骨颈骨折中,42例出现股骨头缺血坏死(9.4％)。分折发现股骨头缺血坏死的发生与病人年龄、骨折类型、暴力大小、手术时间、手术内固定方法等有明显关系;股骨头坏死后不一定出现明显症状;头坏死程度与髋功能评分之间无明显相关,故应以病人的症状与功能作为主要手术指征。

In our series of 725 cases of fracture of femoral neck,438 cases of have had an average of 6. 9 years follow up .of them 42 cases of is-chemic necrosis of femoral head were found and analyzed. The occurrence of ischemic necrosis of the femoral head shown to be closely related to the age of patient, fracture type,the force of violence on in jury, interval between operation and trauma and the method of internal fixation.Symplons after femoral head necresis were not always obvious and the functional scores of the hip were not always correlated to the severity of necrosis. The indication of operative management should base mainly on the symptoms and functional status of the patients. The importance of long term follow up is also stressed in the paper.
