Methods:9 patients including 8 male and 1 female were included in this study.2 patients suffered from both side of ANFH,5 were righe side and 2 were left side.X-ray,CT and MRI were performed before the surgery.4 hips were classified as ARCO stage 1,7 hips were stage 2.All the patients were treated as follows:the area of NFH and cystis degeneration were detected and bouche decompression was done through X-ray with C-arm,and the necrotic bone was cleared for the pathologic diagnosis under the monitoring of arthroscopy.And then the non-cell based tissue engineering bone, which was the complex of autologous red bone marrow and osteoinductice absorbing material containing BMP,was transplanted into the body.
本组9例,男性8例,女性1例;双侧股骨头坏死2例,右单侧股骨头坏死5例,左单侧股骨头坏死2例;术前均行X线摄片、CT、MRI 检查,ARCO分期:Ⅰ期4髋,Ⅱ期7髋;C型臂X线透视下行股骨头坏死区和囊性变区定位、髓芯减压,关节镜监视下,刮除坏死骨送病理;植入由自体红骨髓与含BMP的骨诱导活性材料复合成的非细胞型组织工程骨,并用空心钛钉支撑股骨头软骨下骨质。

Results MRI findings of central neurocytoma are specific in 5 cases. The ganglioglioma was found in the tempora and occipital lobe in 7 cases,in the brainstem in 1 case, cystic-solid tumor was observed in 5 cases with extramural nodule in 3 cases, obviously thickened gyri were revealed in 1 cases and central necrosis in 2 cases.The 3 cases of Lhermitte-Duclos disease include the specific molecular layer imaging features.

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。
