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.

摘 要］目的：探讨成人股骨头缺血性坏死的早期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。

Months later, BMD in Sham and OVX-2 were (1.22±0.07)g/cm2 and (0.86±0.09)g/cm2. BMD in OVX-2 decreased by 29.5% compared with that in Sham group. Histomorphologically, trabecular bone decreased significantly in OVX-2 group compared with that in control groups.

ResultsThe organization structure of experimental group was disorganized, cracked,and the bone trabecula was rarefactive and non-intact . There were a great number of empty lacune in bone trabecula.

结果实验组组织结构紊乱，破碎，骨小梁稀疏、不完整，有大量的空骨陷窝，而对照组骨小梁相对较完整、排列整齐，骨小梁中的骨细胞清晰可见，偶见空骨陷窝。

"Histologic studies evaluating SLT have shown that, unlike argon laser trabeculoplasty, there is no scarring of the trabecular meshwork," write Shlomo Melamed, MD, and colleagues from the Goldschleger Eye Institute, Sheba Medical Center, in Tel Hashomer, Israel."Clinical results have shown the treatment to be effective and safe in patients with primary open-angle glaucoma and in patients treated previously with ALT."

Goldschleger眼科学校的Shlomo Melamed博士表示，评估SLT的组织学研究显示，小梁成型术与氩雷射不同的是，它不会造成小梁组织网结疤，临床的研究结果显示，对於开放性青光眼初期患者及之前以ALT治疗的患者而言，小梁成型术是有效且安全的治疗方式。
