Abstract
A prosthesis assembly configured for use with a scapula in one embodiment includes a spherical humeral component, an elongated glenoid bearing including a first bearing surface with (i) a first spherical end portion with a first radius of curvature, (ii) a second spherical end portion with a second radius of curvature, and (iii) a central portion located between the first spherical end portion and the second spherical end portion, and a first coupling portion extending from a second bearing surface opposite the bearing surface, and a base configured to rotatably support the elongated glenoid bearing, wherein the first radius of curvature is substantially equal to the second radius of curvature and the central portion does not have a radius of curvature that is substantially equal to the second radius of curvature.
