Bone is a highly vascularized connective tissue, and adapts to the role as a mineral storage and source of haematopoiesis. In addition, it aids in the support and protection of internal organs and is involved in the mobilization of human beings through their resistance and mechanical training props and levers. This set of bones and cartilages is called skeletal system and is affected by certain acute and chronic diseases. The hip joint is the most important for the mobilization of human beings. To restore mobility to the person who presents any alteration or disease, it is necessary to replace this joint with prosthesis. The performance of these new devices and the behavior of the bone tissue depend on the magnitudes of the loads applied to the prosthesis and the bone as well as metabolic and immunological factors. This work carried out a simulation and computational analysis with application of boundary conditions (using the ABAQUS/CAE software) of the medullar canal of the right femur, in the presence of a not cemented hip prosthesis, previously designed at INABIO. The results obtained show alterations at the level of the femoral neck in the areas of Gruen 1 and 7. Also, a novel finding was observed in the femoral diaphysis in areas of Gruen 3 and 5, which are distorted by applying loads and boundary conditions described by Bergmann and Heller.
