Today, total hip replacement surgery can be performed at many Vietnamese hospitals. However, all total hips in Vietnam are now imported from foreign countries. These hips are expensive and their designs do not accurately match with most Vietnamese patients. Designing total hips for Vietnamese patients is a demand at the moment. This paper presents a method to get some important geometrical parameters of Vietnamese proximal femur by using reverse engineering. In this method, the CT images of the femur were used as input data for 3D modeling in Mimics to get the 3D model of the femur. CATIA V5 was used to determine the geometric parameters of the proximal femur. The measured data can be used to design femoral stem in the standardized size set of the total hip for Vietnamese patients.
