Abstract
A cotyloid cavity prosthesis consists of an outer shell ( ) and a bearing insert ( ) held together by a locking device ( ). The locking device comprises an elastic lip ( ) and an undercut surface ( ) interacting with the latter. The dimensions are chosen such that, once mounted, the tip ( ) of the lip rests on the undercut surface ( ), with bending deformation of the lip ( ). In order to accomplish the latter, the undercut surface ( ) forms a smaller angle with the center axis of the prosthesis than does the deformation line of the tip ( ) of the lip.
