The study of the biomodel between the femur bone and the hip prosthesis cotyle focuses on the use of the finite element method (FEM) to simulate the biomechanical behavior of the femur bone and the cotyle of the hip prosthesis. The study is based on 3D models generated from CT scan data from patients with hip replacements. The results indicated that the distribution of the load on the femur and cotyle varies according to the different positions of the cotyle. In addition, different stress patterns were observed in the femur bone and the cotyle of the prosthesis, suggesting the need to consider these variables when redesigning hip replacements.
