Abstract:
A method for testing a ceramic socket insert of a hip joint endoprosthesis in which, in use, a spherical head articulates against a functional inner surface of a ceramic socket insert which is anchored in a pelvic bone by means of a socket housing, the method comprising:providing the ceramic socket insert in a holding arrangement; applying a predetermined pressing force to a predetermined sub-area of the functional inner surface of the ceramic socket insert, the predetermined sub-area symmetrically surrounding a pole of the inner surface of a ceramic socket insert, the predetermined force being such that stresses generated in the ceramic socket insert are higher than stresses generated in the case of a physiological load; and applying a supporting force to a sub-area of an outer surface of the ceramic socket insert to counteract the pressing force.
