股骨头坏死塌陷的预测和防治

对股骨头坏死(FHN)塌陷的预测和防治的各种方法加以综述，为以后临床应用提供理论参考。通过CNKI、VIP、CBM及外文相关的文献检索，并阅读、归纳，概述目前所用的相关方法和技术，发现影像学检查特别是X线、MRI对FHN塌陷的预测具有重大价值。防治的方法有多种，包括非手术和手术治疗。FHN塌陷受诸多因素影响，目前研究多局限于某个方面且样本量偏少，因此对预防塌陷所进行的大样本、不同方法分层比较的研究是非常必要的。对于FHN高危人群出现髋关节疼痛的应尽早行有效的影像学检查，对于已经坏死的股骨头应设法预测其塌陷的可能性，对于有可能塌陷的根据不同病变施以髓心减压术或带血管蒂骨移植术等方法。对高危人群股骨头塌陷早期预测，早期防治对FHN患者预后起至关重要作用。

Forecasting and prevention of collapse in femur head necrosis

By discussing different ways on prediction,prevention and treatment of femur head necrosis(FHN),to provide a theory reference for future clinical application. By searching,reading and summarizing related-literatures through CNKI,VIP,CBM and foreign-related literature,to sum up the relevance methods and techniques of currently used. It was found that imaging study(especially X-ray and MRI) was of great importance in prediction. There were several ways(both non-surgical or surgical)for prevention and treatment. FHN collapse was affected by many factors,but most of the researches were all focus on one aspect of the mechanism and based on small samples. It is necessary to have a research with a large sample and to compare the effect on different treatment. Early and effective imaging inspection is needed for high risk group of FHN;possibility of collapse should be predicted for existing FHN;core decompression or vascularized bone grafting are required for collapse of high risk group. Early prediction and treatment are essential for FHN patients.
