MICRO AND MACRO SHAPE DEVIATIONS OF THE CONTACT AREAS OF THE HIP JOINT ENDOPROSTHESIS

Popis výsledku v původním jazyce

The paper deals with the problems of ceramic head of hip joint endoprosthesis destructions, and with assessing the impact of shape deflections of conical surfaces on the tensile stress in the head. Concerned are shape deviations from the ideal conical surfaces of the stem and the head of the endoprosthesis. The shape deviations may be modelled at the macro-level - this concerns model shape inaccuracies such as deviation from the nominal degree of taper, ovality, and their combination, or, possibly, at the micro-level - when the stochastic distribution of unevenness on the contact areas is respected. The problem of stress in ceramic heads was solved using the algorithm of the finite element method - system ANSYS under ISO 7206-5 loading. In the paper are presented and analysed the results of solution of the macro-level shape deviations and micro-level shape deviations, obtained from measurements made on the cones of stems and heads.
