3-D STRUCTURAL SIMULATION OF A HIP PROSTHESIS

This work aims to focus attention on partial or total prostheses obtained through digital imaging and EBM 3D printing, or on those prostheses made from the materials most used in current medicine. We will focus on the section of the acetabular cup, which represents the “heart” of the prosthesis itself, as it is the point where contact pressures arise, that is, those pressures and efforts that have led to failure and wear in the past. of prostheses. The research is performed for a representative case, in which the personalized hip prosthesis made using the 3D technique is used as an osteosarcoma treatment process. The article describes all the phases of the structural simulation by identifying a series of load scenarios for the biomechanical system consisting of the pelvis and endoprosthesis. The prototyping p
