Biomechanical fundamentals for designing machines that allows wear testing

There are few machines developed to produce wear on a prosthesis so they are basically to evaluate the behavior of the knee and hip. Most of this equipment are either prototypes or incomplete devices, this is because this machines do not reproduce the movements of the body. The investigation presented in this article, focuses the fundaments of biomechanics to design and manufacture a machine that allows wear at the ankle joint. So that, the use of tomography or magnetic resonances with combination with computational programs allows the generation of an ankle joint model. This was realized in order to obtain all geometries of a personalized model for an endoprosthesis design. Used as a base to develop a personalized machine able to simulate movements of this joint, which consist of 3° of freedom; flection-extension, inversion-eversion and abduction-adduction. Likewise, it permit the simulation of the body load during the motion process.
