The purpose of the work is to obtain size and geometry numerical data of femur bone for designing femoral stem of total hip joint arthroplasy to fit for Indonesian patient with normal hip joint structure. Geometry data of femur bone was taken by both  X-ray and CT scan methods. The X-Ray anatomy digital objects were taken from different angles at certain intervals as input data to reconstruct anatomical objects. Slicing of femur bone imaging taken by CT scan has a constant interval. Data obtained from both CT scan and X-ray were compared. A solid model of bone is used as a visual-tactile representation, planning surgery (surgical) and simulation tool for physicians. In this work the data input was used for design of a total hip joint arthroplasty (THA) femoral stem. The work reported in this article is considered as a preliminary stage of the development of total hip joint arthroplasty devices for being fit to local (Indonesian) patients with hip joint disorders. The preliminary designs developed in this work is suit for many kind materials, however, for the implementation into manufacturing works, the use of Titanium Alloys need to consider for appropriate femoral stem designs by taking into account the available of tools and effectiveness of femoral stem production, made of the materials.
