The paper deals with the problems of ceramic head of hip joint endoprosthesis destructions. Concerned are shape deflections from the ideal conical surfaces of the stem and the head of the endoprosthesis that were modelled at the macro and micro-level. The problem of stress in the head was solved using the FEM, the Weibull probability model was used for solving the head cohesion failure probability problem. The results of computational modelling are compared with the data obtained by experimental modelling.
