METHOD FOR CHECKING CERAMIC BALL HEADS FOR HIP-JOINT PROSTHESES

摘要

The invention relates to a method for checking ceramic ball heads (3) for hip-joint prostheses which have a receiving space (8) with a conical side face with a clamping cone angleγand a cone inlet (7) and are subjected to a pressure in order to check areas of the receiving space (8). To ensure that all the checked ball heads (3) also remain functionally ready for relevant, oblique in vivo load situations without suffering damage, it is proposed that only the area of the cone inlet (7) is subjected to a radial force perpendicular to the longitudinal axis of the ball head (3).
