Abstract
The hip joint socket is formed of a socket body of relatively elastic material, for example of plastic, and one or more reinforcement rings which are shrunk fit on the socket body under a prestress. The rings impart rigidity to the hip joint socket. The rings may protrude from the contour of the socket body or may have projections which protrude from the contour of the socket body in order to improve fixation in a cement bed or pelvic cavity.
