objective to evaluate early signs of avascular necrosis of femoral head in adult 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 in 13 femoral head.twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.there were fracture under the cartilage and light subsid in 5 cases.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.
