Composite implant

A composite interbody vertebral implant (10) for facilitating fusion of adjacent vertebrae. The implant includes a first endplate (12) of a porous metal material and a second endplate (14) of a porous metal material which are configured to allow bone in-growth. The implant also includes a polymeric...

Zusammenfassung:	A composite interbody vertebral implant (10) for facilitating fusion of adjacent vertebrae. The implant includes a first endplate (12) of a porous metal material and a second endplate (14) of a porous metal material which are configured to allow bone in-growth. The implant also includes a polymeric body (16) positioned between and bonded to the first and second endplates (12,14) such that polymeric material of the polymeric body (16) is impregnated into pores of the first and second endplates to bond the components together. The implant include a cavity (26) extending through the composite implant (10) configured to receive bone growth material to facilitate fusion between a first vertebra and a second vertebra.
