Stress and reliability analyses of ceramic femoral head of hip joint endoprosthesis, with view to local shape deviations of cone contact areas
Original language description
At present, implants are frequently used in clinical practice to return functionality to various parts of the human body. One big group make the implants of joints, one of the most frequently operated joints of the human body being the hip joint. At present, the problems of reliability of ceramic femoral heads for hip joint endoprosthesis are topical, as in a not negligible number of patients their destruction in vivo had taken place. Therefore stress and reliability analyses of the ceramic heads were mmade using computational modelling aimed at finding the causes of the head destruction. In the course of computational modelling it was stated that a pronounced influence on the stress and, hence, the reliability of the ceramic head, had the global and local unevenness of the cone contact areas of the head and the stem. Fig. 1. The stress and reliability studies made up to now have taken into consideration only the influence of model manufacturing inaccuracies, such as deviation from nom
