Abstract:
1. A composite interbody vertebral implant for facilitating fusion of adjacent vertebrae, the composite interbody vertebral implant comprising: a first body of a porous metal material defining a plurality of pores formed by a metallic scaffold configured to allow bone in-growth from a first vertebra; a second body of a porous metal material defining a plurality of pores formed by a metallic scaffold configured to allow bone in-growth from a second vertebra; a polymeric body of a thermoplastic polymeric material positioned between the first body of porous metal material and the second body of porous metal material; wherein a first interface layer between the first body of porous metal and the polymeric body includes the polymeric material impregnated into the pores of the first body of porous metal; wherein a second interface layer between the second body of porous metal and the polymeric body includes the polymeric material impregnated into the pores of the second body of porous metal; and a cavity extending through the composite interbody vertebral implant configured to receive bone growth material to facilitate fusion between the first vertebra and the second vertebra.
