Designing a testing device for customized hip prosthesis

Abstract

The practical reference of this article is part of the technical and medical field of designing, modeling and testing of hip prostheses. The purpose of the article is to present a stand that tests the hip orthopedic prostheses. After the initial design, the whole assembly was redesigned both dimensionally and functionally based on the results obtained by the finite element method. The main results fromthe design of the stand are both the wide range of types of hip prostheses that can be tested as well as the actual simulation of the kinematics of the joint. The simulations performed correspond to the different daily actions: walking, running and other special conditions. The practical implications of this research are the possibility of testing the time endurance of prosthesis in the laboratory condition. The results obtained from this research can be applied to the development of new generations of prostheses, starting from materials with better endurance and reaching aspects of shape and customizableoptimal dimensions.
