ABSTRACT:
An intervertebral disc prosthesis comprises a first endplate, a second endplate, and a bearing surface positioned between the first endplate and the second endplate. The bearing surface may be provided by a mobile bearing disc including a convex bearing surface configured to engage the first endplate and a concave bearing surface configured to engage the second endplate. The multiple bearing surfaces of the mobile bearing disc engage articulating surfaces on the endplates to form a plurality of articulating joints. Each articulating joint is configured to facilitate a particular type of movement for the segmental unit. Furthermore, each articulating joint is defined by a distinct center of rotation. The contact pair formed by the convex bearing surface of the bearing component and the concave bearing surface of the first endplate may provide a flexion/extension center of rotation for the prosthesis. The contact pair formed by the convex bearing surface of the bearing component and the concave bearing surface of the first endplate may provide a lateral bending/torsional center of rotation for the prosthesis.
