PartⅢThe study of macrography, histology, pathology and apoptosis After the impactive injury of acetabular cartilageObjective To discuss the change of short and long peoriod for the impactive injury of acetabular cartilage by using different energy,the pathological mechanism of chondral injury and the relation between chondrocyte apoptosis and cartilage degeneration. Methods fifty-four New Zealand white rabbits were divided into high energy and low energy groups randomly, of which the two groups which were made through the homemade impactive equipment by impacting the right acetabular cartilage of rabbit at 35cm and 15cm with 0.400kg weight vertically and simulating the mechanism of impactive injury of human acetabular cartilage.

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。

The value of the plainradiographs of pelvic was limited in the diagnosis of acetabular fractures and thedecision of pre-operative planing.EBCT images could show acetabular fractures in detail.Onthe basis of EBCT images,rational treatment might be drawed,but working out the detail ofoperative plan,orthopedist had to have rich experience in observing EBCT scan.The imagesof EBCT 3D reconstruction might provide exact guidance to formulate operative plan,thusEBCT 3D reconstuction now was the best method in the diagnosis of acetabular fractures.

骨盆平片诊断髋臼骨折是粗浅的，对制定治疗方案帮助有限；EBCT平扫能显示骨折的详细情况，并由此选择合适的治疗方法，但要制定具体的手术方案，需要临床医生有丰富的阅片经验；EBCT三维重建对制定详细的手术计划可提供正确指导，是目前最理想的诊断髋臼骨折的方法。

Grouping lesional and homeochronous normal hip to pair, dynamic measuring AI and AI in each age groups of lesional and normal hip on before reduction、after reduction 3rd month、6th month、9th month、12th month, describing the characteristics of acetabular development in each age groups on every observation time-points, comparing the difference of lesional acetabular development with normal acetabular physiological development.

并以患侧髋关节与同期健侧髋关节进行配对分组，动态测量各年龄组患儿患、健侧髋关节在复位前、复位后第3、6、9和12个月时的髋臼指数和髋臼深度与宽度比值AI(D/W，描述各年龄组在各时间观察点上髋臼发育的特点，比较患侧髋臼发育与健侧髋臼生理发育的差异。

METHODS: The distances from anterior acetabular margin, posterior acetabular margin to anterior inferior iliac spine, iliopubic eminence and pubic tubercle were measured, respectively to determine and make serial cross-sections of the acetabular anterior column. In addition, the safe angle of screw entry on all entry points of each cross-section was measured, and all data were put into software SPSS 10.0 for statistics process.

分别测量20个半骨盆标本髋臼前、后缘到髂前下棘、髂耻隆起和耻骨结节的距离，确定和制作髋臼前柱系列断面，并测量各断面上各进钉点的安全进钉角度，将测量数据输入到SPSS10.0软件进行统计学分析。

And then measured for acetabular rim opening width and acetabular anteversion angle in different transection planes in computer with related software.

并对不同横断面的髋臼缘开口宽度、不同横断面髋臼前倾角进行定量测量。

Objective To explore the advantages and disadvantages of extensile acetabular approach and discuss the effect of the surgical treatment of the complex acetabular fracture.
