ABSTRACT:
A ball-and-socket joint has a race with bearing balls interposed between the head and the socket of the joint. The race is secured to the head. In use as a prosthetic hip joint, the formation of metallic debris is reduced or completely eliminated thus eliminating or at least reducing the occurrence of the need for corrective surgery. The hip joint is of an unconstrained type which often enables correction of an accidental dislocation of the joint without surgery.
