     [摘要] 目的：探讨成人股骨头缺血性坏死(ANFH)的早期CT征象并指导临床治疗。方法：对临床疑诊ANFH的全部病例均行X线平片及CT检查，分析ANFH的早期CT征象。结果：早期ANFH的CT表现：31例38个股骨头，其中13个股骨头骨小梁呈放射状高密度的“星状征”，骨小梁境界清楚、锐利，属Ⅰ期；25个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属Ⅱ期；并有5个股骨头在Ⅱ期影像学改变基础上出现软骨下骨折及轻微塌陷，属Ⅲ期。治疗结果：Ⅰ期行钻孔髓内减压术，Ⅱ、Ⅲ期行钻孔减压植骨术。结论：CT可以诊断早期ANFH并分期，而且能很好地指导临床治疗。

    Abstract：Objective To evaluate early signs of avascular necrosis of femoral head in adult (ANFH) by CT and to guide clinical treatment.Methods The cases with suspicious diagnose of ANFH were scaned in the both hip joints by Xray and CT to find the early signs of ANFH with CT.Results Early signs of ANFH using CT showed that, in 38 femoral heads 31 cases, there were radiate star shape of highdensity osteosclerosis of the trabeculae (stageⅠ) in 13 femoral head.Twentyfive femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately lowostedensity area and cyst change (stageⅡ).There were fracture under the cartilage and light subsid in 5 cases (stageⅢ).The cases in stage Ⅰwere given decompression, while the pationtsresul in stageⅡand stageⅢ were given decompression and ostetransplant.Conclusion CT results show that the sign of the highosteodensity and low osteodensity and cyst change can disply early ANFH. It can also instruct the clinical treatment of ANFH. ......
