股骨头

Methods It was found that 31 of 147 cases followed-up for 5 to 10 years appeared femoral head necrosis.

方法对 147例股骨颈骨折术后的病例进行了 5～ 10年随访，发生 31例股骨头坏死。

The experiment provides a basis for treatment of the necrosis of the femoral head.

为股骨头坏死这种新的治疗方法提供实验依据。

In addition, the magnetic noose tool was used to outline the contour line of inside and outside boundary, and obtain the inside and outside contour line of every layer of the femur. The rabbit femur was scanned by industry CT starting from the upper extreme of the femur, vertical to femoral ordinate axis line (slice space=1 mm).

再用磁性套索工具勾勒各层图像的内、外边界线，得到各层面股骨内、外轮廓曲线，采用CT 扫描机对兔股骨进行扫描，自股骨头上端起，由近端向远端垂直于股骨纵轴行CT 扫描，层间距为1 mm。

Avascular Necrosis of the Femoral Head is a common disease in osteopathy clinic xhich is difficult to be treated ,involving 20 millions people in the world.

股骨头缺血性坏死(Avascular Necrosis of the Femoral Head，以下简称ANFH)是骨科临床上的常见病、疑难病，世界约有2000万患者，发病高峰在25—50岁，男女比例约为4：1。

Disappearance of the "asterisk sign" and appearance of high density osteosclerosis in various shapes are early CT features of AvNFH.

股骨头内"星芒征"消失，出现多种形态的高密度硬化区是本病的CT早期征象。

CT scans also documented osteosclerosis in the cortical edge of 4 femoral heads.

随访病例股骨头密度及外形表现出一定规律。

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。

［Objective］To study the treatment and complications of posterior dislocations combined with fractures of the femoral heads (Pipkin's fracture).

［目的］通过治疗随访21例髋关节后脱位合并股骨头骨折，探讨治疗方法及并发症。

During the gait cycle, forces are directed against the prosthetic femoral head from a polar angle between 15 and 25 degrees anterior to the sagittal plane of the prosthesis.

在步态周期中，力从假体矢状面前15°～25°的极角作用于假体的股骨头。
