Originální abstrakt

The paper contains the results of the stress and reliability analyses of the ceramic head of the total hip joint endoprosthesis under testing conditions in accordance with the norm ISO 7206-5. The axisymmetric production inaccuracies of the contact taper of the head and the stem are considered. The head stresses are obtained from the computational methods (finite elements) and the head reliability is based on the Weibull weakest link theory. The effects of the production inaccuracies on the head’s hoop stress and the head’s contact pressure along the contact taper are analyzed in detail, because the maximum tensile stress is located in this region. Finally, the effect of the aforementioned production inaccuracies on the head’s failure probability during the loading is shown.
