Bone trabecula just under the calcaneocuboid articular surface was compact and redundant, with the thickness about 5 mm. Conclusions: Screws can be implanted into the calcaneocuboid articular surface where is filled with compacted trabecula.

结果：跟骨骰骨关节面的横径为(22.67±2.14)mm；其内倾角为(60.4±7.1)°；紧邻跟骨骰骨关节面关节面下的压力骨小梁是致密的，厚度大约为5 mm，向后方和下方的骨小梁逐渐变得稀少、疏松。

Microscope examination:in group A,at 2 weeks,a few inflamatory cells appeared in the holes with many osteoblasts and ostoid appeared around the drilled holes.At 8 weeks,marrow formed in the drilled holes in group B,at 2 weeks,there were a large amount of osteoblasts in the drilled holes and some ostoid formed around thc drilled holes.At 4 weeks,the drilled holes were full of trabeculae.At 8 weeks,the trabeculae matured with the marrow appeared in the intertrabecular space.

组织学结果：2周时A组钻孔区出现少许炎症细胞，边缘出现较多成骨细胞并有骨组织形成，至8周时，钻孔区内形成骨髓组织，只在边缘形成骨小梁结构。2周时B组钻孔区有大量的成骨细胞，边缘有较多骨组织形成，4周时钻孔区内充满重生骨小梁结构，8周时钻孔区内骨小梁成熟，小梁有骨髓组织填充。

No difference were found in all dose Epimedium total flavonoids groups,percent of bone trabecula area and number of bone trabecula showed increasing pattern and resolving powder of bone trabecula showed decreasing pattern.

淫羊藿总黄酮三个剂量组之间没有差异，但在骨小梁面积百分数、骨小梁数量上有上升的趋势，骨小梁分离度则有下降的趋势。

Resultsforty-eight patients in this report were followed up from 6 to 24 months. based on joa low back pain score, there were 36 patients was in excellent result, 8 in good and 4 in fair, the satisfactory rate was 91.67% and effective rate was 100%.using circular saws in posterior lumbar interbody fusion has advantagas of good visualization profit removing disc tissue, preventing neurovascular injuries, and making good bone grafting bed.

结论应用环锯取骨植骨法，有以下3大优点：(1)手术视野大，椎间盘摘除彻底，既可避免摘除椎间盘时损伤重要组织，又易于构建良好的植骨床，有利于植骨融合；(2)取骨方便、安全、损伤小、出血少，既缩短了手术时间，又避免了取骨处并发症的发生，本术式平均手术用时90 min，出血量00 ml；(3)植骨融合率高，术后效果好。

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。
