THREE-DIMENSIONAL MODEL OF A HIP PROSTHESIS

Serious pathological problems of the hip joint can be solved surgically, in some cases by joint prosthesis. For this reason, it is very important to be able to shape, in a first phase, the components of the prosthesis, which can then be tested virtually. For this purpose, the components of the prosthesis with fixation pins were firstly scanned three-dimensionally. This operation resulted in a model of a "cloud of points" which was subsequently transformed into virtual surfaces, then into virtual solids. These virtually solid components were assembled in a parameterized virtual environment. This prosthesis can be inserted into a biomechanical model of the hip joint and tested using the finite element method. At the end of the paper important conclusions were drawn.
