髋

The prosthesis involved biotype in 18 cases (24 hips), cemented 3 cases (5 hips), and mixed type 3 cases (4 hips) and made of metal alloy shaft and polymer polyethylene liner.

所用假体包括生物型18例(24髋)、骨水泥型3例(5髋)、混合型3例(4髋)，均为金属合金股骨柄对高分子聚乙烯内衬。

Procure normal 3D finite element model of acetabulum by adding mechanics parameter to the haunch bone model with Ansys software.

正常髋臼及不同面积后壁骨折条件下应力分布情况按设定骨折线在模型上将髋臼后壁进行拆分后获得髋臼后壁1／3、2／3、3／3骨折的三维可视模型和有限元网格模型。

Explore and improve the method of performing biomechanics experiment with digitalization mechanics model. 1、Construct 3D finite element model of normal acetabulum: Scan the pelvic example of human body with CT, restitution three-dimensional visible haunch bone with correlated software; investigate the method of 3D image reconstruction with plane images.

正常髋臼三维有限元模型的构建：通过对大体标本进行薄层CT扫描，利用相关软件重建三维可视髋臼，研究利用平面图像重建高仿真三维影像的方法；再利用有限元分析软件将髋臼力学参数赋值于可视模型上，使其具备力学性能，同时研究如何改进赋值方法，使有限元模型力学性能更接近于大体标本。

Acetabular posterior wall was started from top of acetabulum to the junction of acetabular posterior wall and ischium. This area was equally divided into two parts: part A-superior, part B-inferior.

分组：髋臼后壁范围为从髋臼顶点至髋臼后壁与坐骨枝相交处，将其等分为两部分，上部为A区，下部为B区。

The acetabular labrum is an important element of physiological functions of acetabulum, while acetabular labral tear is a biomechanical cause of hip pain.

髋臼唇是维持髋关节正常生物力学行为的重要组成部分，髋臼唇撕裂是引起髋部疼痛的原因之一。

Results: The labrum was the widest at the point of anterosuperior 90°(8.82±2.20) mm and the thickest at the point of midsuperior (5.56±1.56) mm.

结果：髋臼唇在距髋臼顶点前90°最宽(8.82±2.20)mm，在髋臼顶点处最厚(5.56±1.56)mm。

The excellent and good rate was 89.13%. In the DHS, there were 2 cases with greater trochanter fractures, 1 case with over boring, 2 cases with pulmonary infections, 2 cases with urinary system infection and 1 case with coxa vara. In hollow pressing whorl bolt internal fixation, there were 1 case with coxa vara and I case with deep phlebothrombosis.

采用动力髋螺钉固定者术中大转子骨折2例，髋螺钉孔钻孔过深1例，术后发生肺部感染2例，泌尿系感染2例，髋内翻1例；采用空心加压螺钉固定者术后出现髋内翻1例，发生深静脉血栓1例。

The authors found that the prealence of protrusio increased to approxi- mately 35.9% by the age of twenty years and then it plateaued; howeer, its presence did not correlate with osteoarthritic changes as measured with the Iowa hip score in patients more than forty years of age.

作者发现髋臼前突的发病率在20岁时增加到35.9%然后进入平台期，但其表现与骨关节炎改变并不成比例（IOWA髋指数，年龄大于40岁）；对有症状的患者来说，髋关节前突与髋部疼痛之间呈正相关关系，关节间隙宽度与髋前突间呈负相关关系，提示髋关节前突的力学因素对关节退变有一定作用，但可能不是主要因素。

This three-dimensional image database would be helpful to new recognition of the acetabular, especially, to serve as an important reference base for the operation design and anatomic reconstruction of acetabula.

提示应用反求工程可以建立髋臼三维图像数据库，有助于对髋臼骨形态的重新认识，可为髋臼骨折的手术设计和髋臼缺损的解剖重建提供重要的参考。

Methods Acetabular index,CE angle,acetabuar head index and acetabular depth were carefully measured on roentgenograms of 120 developmental dysplasia of the hip cases over 5 years post-operation and 120 normal children whose age were similar to sick children as control group during following-up.

方法对比120例术后5年以上的双髋X光片和随机选择的与随访时年龄相近的120例正常的双髋正位X光片，仔细测量髋臼指数、CE角、臼头指数和髋臼深度，对单侧者还进行双侧对比测量。
