摘要：
A socket or socket insert for a hip joint prosthesis, the shaft of which can be coupled with a ball head which in turn can be inserted in a rotatable manner in the hemispherical recess of the socket insert wherein the shaft can be implanted in the femur and the socket insert can be implanted directly or via a hip socket in the pelvic bone. To avoid squeaking, the socket and/or the socket insert are asymmetrically in their inner or outer geometries.
