Claim:
An intervertebral implant for promoting fusion between adjacent vertebral bodies, comprising: an inferior laterally extending member having a first anterior aspect and a first posterior aspect separated at least in part by a central void and joined together by respective end members; a superior laterally extending member having a second anterior aspect and a second posterior aspect separated at least in part by the central void and joined together by respective end members; wherein said inferior and superior laterally extending members comprise a biocompatible metal having an outer surface with substantial unevenness for promoting bone growth thereon; and a body made at least in part of a biocompatible polymer, the body being positioned between said inferior laterally extending member and said superior laterally extending member, wherein said central void extends through an upper surface of said inferior laterally extending member and a lower surface of said superior laterally extending member and through opposite first side portions of said implant between said upper and lower surfaces, said central void being at least partially enclosed between opposite second side portions of said implant that extend between said first side portions by said body, and wherein said body is positioned so as to avoid blocking portions of said central void that extend through said first side portions.
