%X Despite the widespread use of reverse total shoulder arthroplasty, there is still a problem of conflict between the polyethylene cup of the prosthesis and the scapula, which over time causes the phenomenon of notching. In order to circumvent this problem correctly, several innovations have been proposed regard to the implementation method. In this context, the aim of this work is to study the biomechanical behavior of new implantation methods using different glenoid configurations in order to avoid the notching phenomenon between the cup and the scapula. The study was carried out using virtual prototypes of the shoulder prosthesis assembly. Forum CT scan images, three-dimensional models of shoulder bones were reconstructed. The implantation of the prosthesis in 3D model was performed in collaboration with an experienced surgeon from the Caduceus Clinic (Oran, Algeria). The obtained models were imported to finite element calculation software. After the validation of the numerical model using the literature results, we assessed the biomechanical behavior of four implantation methods under the same boundary conditions and abduction movements. Among the used methods, the BIO-SR lateralization method offers significant biomechanical advantages in terms of the forces applied to the glenoid during the abduction movement.
