A61F 2/44

US Classification:

623 1711, 623 1716

Abstract:

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

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An implant is provided that includes a body having a convex and tapered leading end, a convex trailing end, opposing generally planar sides extending between the leading and trailing ends and superior and inferior surfaces. An opening extends through the body between the superior and inferior surfaces. The implant further includes a plurality of protrusions provided on each of the superior and inferior surfaces. Each protrusion has a flattened distal surface. The leading end includes first and second inclined surfaces and an intermediate surface, with the first inclined surface sloping downward from the superior surface to the intermediate surface and the second inclined surface sloping upward from the inferior surface to the intermediate surface.
