The modelling of the anatomical structures of pelvis and femoral bone with implanted endoprosthesis of hip joint have been presented in the doctoral dissertation. Various solutions of clinical endoprosthesis: cemented and uncemented ones of different material configuration in movement zone and varied constructions of stems and cups have been considered. The diagnostics of spiral computer tomography has been used to model the anatomical structures. The different solutions of endoprosthesis together with simultaneous geometrical analysis have been put in reconstructed in 3D anatomical objects. The optimal location of endoprosthesis in conditions of individual patient has been determinated. The tree-dimensional system of loads and constraints has been introduced on the basis of the previously carried out deliberation of biomechanical walk of man. The distribution of stresses, according Huber-Misses-Hencky hypothesis and resultant displacements, has been carried out in numerical models. The three basic cases of load of hip joint: standing on two legs, standing on one leg and the contact of heel with the ground have been analyzed. The cases of increase of load during walk have additionally been analyzed. The results of the work determine the basis to complex elaboration to select the proper system of endoprosthesis for an individual patient.
