中国人种人工髋关节柄部形态曲线的参数设计

通过对８４根中国人成人股骨标本进行正侧位Ｘ光摄影，在Ｘ光片对股骨上端髓腔内侧形态描绘，将描绘好的图像输入计算机，由计算机进行图像处理后提了其曲线形态数据，并通过最小二乘曲线拟合方法将形态数据参数化。对参数化数据作统计分析，并按各参数的分布方式进行不等间隔分类，根据分类结果得到系列人工髋关节不同类别设计时所需的关键数据，柄部曲线形态。

The Curvature Design on Artificial Femural Stem in Chinese Population

Based on A P view geometory and lateral view geometory X ray Photograph, the upper geometric curves of intermedulla were measured from each bone in 84 femur specimens in Chinese population. All curves were parameterized by lest mean square method. A statistical analysis on parameterized data was made for finding out the growth law of femur in Chinese population. The shape of the femur is classfied into 7 types. This results of the research is for the the design of Chinese Type artificial femur.
