[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.
