RESUMO
Objective To study the clinical value of CR system in diagnosing fracture of femoral neck.Methods 108 cases hospital ized with fracture of femoral neck were examined by CR,the results were analysed comparatively with that of the conventional X-ray film taken at the same time.Results CR system could show clearly the various fracture lines according to Garden four types of arthrosteopedic surgery,while 3 cases of Ⅰ type and 5 cases of Ⅱ type were failed to indicate the distinct difference on conventional X-ray films,there were obvious different in positive detecting rate between these two methods.Conclusion CR system,by its function of computer treatment afterwards,can make an early diagnose in time to different types of the fracture of femoral neck,especially in the respect of Ⅰand Ⅱ type which is superior to the conventional X-ray film.
