Abstract

The metallic intervertebral prosthesis is formed of a kidney-shaped body having fishplates extending upwardly and downwardly from the body. Each fishplate has an opening for passage of a bone screw in order to secure the prosthesis to and between adjacent vertebrae. The body is tapered conically from ventral to dorsal and may be fitted in place in the ventral direction. A metal wire mesh may be provided on opposed surfaces of the body for the ingrowth of tissue and ribs may be provided to enhance lateral stability.
