Objective To investigate effect of total hip replacement for severe fracture of acetabulum.

目的 探讨早期全髋置换术治疗严重髋臼骨折的疗效。

To deepen acetabulum,we turned over the external ilium lamina as a hinging graft coving on the femoral head when performing iliumotomy.At the iliumotomy,a dissociate cancellous bone was wadged on the plasted acetabulum for stabilizing it.

病例的手术治疗改进为了更好地解决小儿先天性髋关节脱位的髋臼狭窄，股骨头相对大的臼，头包容；为防止术后并发再脱位；减少股骨头缺血坏死；增加术后髋关节的稳定等问题。

Modify the model by FreeForm software and dissecte the model of haunch bone; import the 3D visible model of haunch bone into Ansys8.0 software. Add mechanics parameter to the haunch bone model, construct 3D finite element model of acetabulum. 2、On the base of common fracture line of acetabular posterior wall fracture in clinical cases, split the acetabular 3D finite element model according to 1/3, 2/3, 3/3 areas fractures of posterior wall after simplify setting, obtain four types of acetabular posterior wall fracture model(including normal condition of acetabulum).

按髋臼骨折Letournel分类标准并根据临床髋臼后壁骨折病例常见骨折线位置，进行简化设定，依次按后壁1／3，2／3，3／3面积骨折将髋臼三维有限元模型后壁进行拆分，获得三种髋臼后壁骨折状态的有限元模型；再模拟双足直立位对髋骨约束设定，分别对后壁正常及不同面积骨折状态模型进行加载，获取各模型应力分布图并记录臼顶负重区、髋臼前壁和剩余后壁在不同后壁骨折状态下应力分布大小及改变。

Results:When unilateral anterior superior iliac spine loaded by transient stress,0-10 ms,stress distributed from posterior superior iliac spine to anterior superior iliac spine,and on the last 10 ms,there were greater stress distribution around cacroiliac joint,acetabulum and pubic branch.When unilateral positive backside of ilium loaded,between 0 ms and 20 ms,stress transmitted along vertical direction of ilium,and after 20 ms,there were greater stress distribution on cacroiliac joint,both pubic branch,ischium branch and acetabulum.

结果：冲击载荷作用于单侧髂前上棘时，0～10ms主要的应力沿髂后上棘到髂前上棘分布，在冲击后期10ms以后，骶髂关节、髋臼和耻骨支都会产生较大的应力分布；作用于单侧髂骨正后方部位时，0～20ms主要的应力沿髂骨纵行传导，应力分布并没有在冲击峰值10ms时达到最大，而是从20ms之后，应力开始向骶髂关节、双侧耻骨支、坐骨支以及髋臼等部位传导并可见到明显的应力分布。

The quantitative measurement parameters included:(1) Anterolateral acetabular lip angle, ALAL,(2) Lateral acetabular inclination, LAI,(3) Transverse rotation of the acetabulum, TRA,(4) Spherical index of ossification center of the femoral head,(5) Diameter of ischium in acetabulum center.

在三维图像上，测量髋臼前外侧缘倾斜角、面髋臼上缘倾斜度、臼横向旋转角、骨头骨骺核球形指数，在横断面图像上测量髋臼中心坐骨的厚度；定性观察：根据髂骨部分髋臼上缘的病理变化，把所有异常侧髋臼分为两组，轻型缺损：髋臼上缘清晰可以辨认，重型缺损：髋臼上缘模糊不能辨认，或形成假臼。

Methods The osteotomy was performed along margin of acetabulum with acetabular wholism rotary to improve acetabulum to cover head of femur.

沿髋臼缘截骨，通过髋臼的整体旋转来加大髋臼对股骨头的包容。

First, sequential tomograms of the hip are obtained from a CT scan; secondly, an accurate and automatic method is used to extract the profile of the acetabulum; thirdly, a hybrid method is utilized to gather fiducial marks on the acetabulum; fourthly, bulky error sampling points are removed. Finally, an ellipsoid fitting method is used to fit the ellipsoid model of the femoral head. Two male sufferers with different necrosis extents are chosen as experimental subjects for contrastive simulation.

首先利用一种精确的自动分割方法在髋骨部位CT序列图像中提取髋臼轮廓；然后使用基于等距栅格采样法与辐条式采样法相结合的混合采样法得到髋臼凹面的空间坐标点集，并剔除其中的误差采样点；最后采用基于二次曲面一般方程的方法拟合原始股骨头椭球面模型。

86 examples patients mild case acetabulum bone fracture, after stock backbone bone fracture processing then repositions, an acetabulum bone fracture heavier bone fracture uses in the opening replacement to be fixed.

86例患者轻症髋臼骨折，股骨干骨折处理后即可复位，髋臼骨折较重的骨折均采用开放复位内固定。
