[The curvature design on artificial femoral 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 classified into 7 types. This results of the research is for the the design of Chinese-Type artificial femur.
