Abstract

An intervertebral device comprises a first endplate assembly including a first exterior surface, a second endplate assembly including a second exterior surface, and a bone in-growth area located on the first exterior surface. The bone in-growth area includes an osteoconductive surface. The intervertebral device also comprises a bone in-growth indicator located on the first exterior surface and an access guide on the first endplate. The access guide is adapted for directing a revision instrument to the bone in-growth area.
