Anthropometric Study of Proximal Femur Geometry and Its Clinical Application
RC Siwach
Abstract
The implants for fixation of proximal femur fractures and joint replacements have been designed taking into consideration of the anthropometry of the western population which vary from other ethnic groups. The present study aimed to study the morphology of the upper end of femur in relation to its various diameters and angles and compare the external and internal geometry of proximal femur as obtained from radiographs, with actual measurements on cadaveric specimens in Indian population. Seventy five pairs (150 bones) of cadaveric femora were studied morphologically and radiologically using standardized techniques to obtain various anthropometrics measurements. These values were compared with those reported in the literature for Hong Kong Chinese, Caucasian, Chinese and Western populations. Data were found to be quite different from them. It is proposed that implants designed for Western populations should be used judiciously and future implants be designed to match the morphology of the Indian bones.
