摘　　要：目的通过观察分析确诊为股骨髋臼撞击症的髋关节的CT表现,找出其影像特点。方法对22侧(21例)髋关节的CT图像进行了分类和影像征象分析。结果 22侧股骨髋臼撞击症髋关节,杵型12侧,臼型10侧。以股骨头骨赘、髋臼缘硬化增生、关节面失光滑、关节面下密度异常四项CT征象做为杵型组和臼型组的对照指标,股骨头骨赘和关节面失光滑有明显差别。结论股骨头骨赘和关节面失光滑这些指标都反映了致病机制的差异。股骨髋臼撞击症的诊断,需要综合考虑临床病史及影像征象。Objective To analyze the characteristic appearances on CT of hips with femoroacetabular impingement so as to find CT imaging features. Methods 22 hips with femoroacetabular impingement were classified, imaging features were analysed. Results Study group of 22 hips with femoroacetabular impingement was divided into cam type group （n= 12） and pincer type group （n= 10）. The imaging features of CT involved acetabular proliferations and sclerosis, abnormol sub- articular bone density, nonsmooth articular surfaces and femoral heads with osteophyte and so on. The last two showed significant difference between cam type group and pincer type group. Conclusion The significant difference of FAI groups in nonsmooth articular surfaces and femoral heads with osteophyte explained different pathogenic mechanism. It is impor- tant for the diagnosis of FAI to comprehensively analyze imaging features and medical history.
