An artificial intervertebral disc for at least partially replacing a diseased or damaged intervertebral disc. The artificial disc includes a concave-convex articulating surface. The artificial disc can be used in the cervical region of the spine, where a concave-convex articulating surface is advantageous for improved anatomical fit and region appropriate kinematics. The artificial disc of the present invention also includes an anchor for attachment to bone.

What is claimed is: 1. A method of providing a prosthetic disc comprising the steps of:removing a portion of an intervertebral disc, thereby creating an intervertebral disc space; andplacing a prosthetic disc substantially within said intervertebral disc space, wherein the prosthetic disc comprises:

What is claimed is: 1. A method of providing a prosthetic disc comprising the steps of:removing a portion of an intervertebral disc, thereby creating an intervertebral disc space; andplacing a prosthetic disc substantially within said intervertebral disc space, wherein the prosthetic disc comprises:a disc body, having a first surface that is comprised of a single articulating surface and a second surface as abuse adapted for fixation to a first bone, wherein a solely convex reference curve having a substantially uniform radius of curvature is formed when the single articulating surface is intersected with a midsagittal plane, and wherein concave reference curves are formed when the single articulating surface is intersected with planes orthogonal to the midsagittal plane.
