Abstract

The present invention relates to an implantable intervertebral fusion device for use when surgical fusion of vertebral bodies is indicated. The implant is comprised of bone conforming in size and shape with the end plates of the adjacent vertebrae and has a wedge-shaped profile with a plurality of footings and grooves located on the top and bottom surfaces.
