Abstract: Abnormality in human joint biomechanics is the main cause of the degenerative disease development, therefore the description and correction of the joint biomechanics is essential for adequate treatment. We present an approach how to obtain the data of a patient and how to use these data subsequently in 3D mathematical models. The magnetic resonance imaging (MRI) of the hip joint is used as a base for 3D simulations. The MRI output has to be transformed into a form readable by our finite element (FE) software. Two transformators were developed for this purpose. To analyse the model as a contact problem, some further transformations are necessary. A contact is assumed between the femur and the pelvis. We compare the results both from the elastic and from the contact analyses.
