SPINAL IMPLANT

摘要

The present invention is directed to a spinal implant, preferably a bioresorbable spinal implant, for insertion between vertebrae bodies. The implant preferably includes an anterior surface, a posterior surface, first and second lateral surfaces extending therebetween, a superior surface for engaging one of the vertebrae bodies, an inferior surface for engaging the other vertebrae body, and a central bore which extends from the superior surface to the inferior surface. The central bore preferably has a generally lobe-shaped footprint. The anterior surface of the implant preferably includes a pair of vertical channels sized and configured to engage an insertion instrument and the superior surface preferably has a convexly curved surface extending substantially from the anterior surface to the posterior surface while the inferior surface preferably has a substantially constant taper extending from the anterior surface to the posterior surface.
