The 3D Virtual Model of a Classical Hip Joint Prosthesis

Abstract:

In this paper were presented the main steps for defining a virtual prosthetic hip. The elements of the classic hip prosthesis were generated, one by one, using direct measurement method. These elements were included in the biomechanical hip system. The entire model was divided in finite elements. Starting from this 3D model, the goal of the research is to determine new geometries and optimized solutions for an innovative hip prosthesis.
