Abstract
An endoprosthesis including a first articulating member formed with a generally concave articulating surface, and a second articulating member formed with a generally convex articulating surface which articulates with the concave articulating surface, the first and second articulating members each having a generally planar attachment surface for attachment to spine structure, wherein the first articulating member includes a contour defined by a cutting surface that cuts through a portion of the first articulating member at a non-zero angle relative to its attachment surface, and the second articulating member includes a contour defined by a cutting surface that cuts through a portion of the second articulating member at a non-zero angle relative to its attachment surface.
