Abstract:
1. A motion-preserving artificial joint comprising: a) a core comprising: a hub, a flange, and a biocompatible elastomer layer surrounding the flange, wherein the hub comprises a rigid material able to maintain a selected height, and a curved surface, and wherein the hub is disposed within the flange so that at least a portion of the curved surface of the hub extends above the surface of the flange; wherein said flange is a rigid component able to provide internal structural support for the elastomer layer, and wherein said flange contains one or more negative spaces and said elastomer layer is molded around said flange and through said one or more negative spaces; b) an endplate comprising: a structural component able to engage a surface, a first low-friction surface that engages the elastomer layer, and a second low-friction surface that engages the curved surface of the hub, wherein the endplate further comprises a low-friction pad wherein the first low-friction surface which engages the elastomer layer is located on the surface of the low-friction pad.
