Based on A-P view and lateral view of X-Ray Photograph, upper geometric curves quedullary canal are measured and drawn from each of 84 Chinese femur bone specimens. All curves are parameterized by least mean square method. A statistical analysis on parameterized data is made for finding out the growth law of femur in Chinese population. The shape of the femur is classified into 7 types. This result of the study is for the design of Chinese-Type artificial femur. that is in accord with the biomechanics characteristic.
