Abstract
A ball and socket joint for implanting in the body is provided wherein the socket portion of the joint can have various orientations with respect to the patient's anatomy, and the orientation used for a particular patient can be selected and/or changed in situ, that is, during or after implantation of the joint. In addition, the configuration of the joint, e.g., constrained versus semi-constrained, as well as the materials making up the socket portion of the joint, e.g., plastic versus metal, can be selected and/or changed in situ. The questions raised in reexamination request Nos. 90/004,732, filed Aug. 26, 1997 and 90/005,596, filed Jun. 22, 1999, have been considered and the results are reflected in this reissue.
