In addition, many studies of patients with AVN showed plenty of special characteristics,such as age distribution and bone quality.Objective:To study the geometric features of proximal femur for the Chinese AVN population,in order to prove the existence of special characteristic of proximal femur for the disease and then develop an AVN-specialized stem evaluated by a validated finite element analysis.Methods:1.The author investigated the standard X-ray data of 127 cases(179 hips) with definite diagnosis of AVN to provide anatomical references for this disease.At the same time,we conducted a meta-analysis of anatomical studies of normal proximal femur data,including the section of LT+20,LT,LT-20 and CFI to identify the potential difference between AVN and normal population.

方法1、通过研究AVN患者标准X线正、侧位片127例(179髋)，获得股骨近端的解剖学数据，利用荟萃分析的方法比较AVN患者股骨近段髓腔特征平面(LT+20，LT，LT-20)及CFI的改变与以往研究数据的差异，并利用创伤性FNF患者资料代替正常人股骨数据进一步比较髓腔前、后、内、外四条曲线段上的差异。2、通过结合现代CAD技术，将内、外、前、后曲线拟合到AVN柄的外形上，选用短柄假体设计，近段设计利用AVN患者骨髓腔CT相对应位置的断面进行修正，设计AVN人工股骨柄。3、计算机三维有限元分析：①使用CAD软件SolidWorks和有限元软件Ansys所建立的髋关节股骨侧假体置换后的三维有限元模型。
