N2 - The purpose of this study was to identify the differences in femoral dimensions among Caucasian and Oriental populations. A total of 268 femora were collected from China, Japan, Korea, Taiwan and the United States. Firstly, the dimensional parameters for measuring femur were identified. These were initially measured on bone specimens to determine the methodology, followed by measuring the same parameter on plane radiographs of the same bone specimen using a board, and digitized with the aim of verifying the repeatability and reliability of the data. Data were analyzed using ANOVA, paired students t test and Pearson’s correlation analysis. The results revealed that Caucasian femora are significantly larger in maximum bone length (BL), head-neck length (HNL), lesser trochanter width and the total width of the distal epiphysis (Wdf). The Beijing femora were found to be the longest and the Japanese femora constituted the shortest bone lengths and smallest angle alpha among the Oriental populations. A strong correlation was observed between Wdf and HD, HNL, Wmc and Wlc in all the populations; however, correlation between Wdf and BL was mild. The angle alpha showed no correlation with BL. This study generated a large database of femoral geometry, which may help pharmaceutical companies to design orthopedic implants for Oriental populations.
