Interbody implant for the spine.

摘要

The implant is tubular and hollow in shape and has an inner cavity (1) bounded by a peripheral wall (2) with communicating apertures (9-12). The wall has an outer surface (4) which is generally circular in shape, two solid side faces (5, 6), and upper and lower surfaces (7, 8) which have the apertures in them. The implant's outer surface has at least one anti-recoil rib (13). The implant's outer wall (2) has the general shape of a truncated cone or ovoid with its larger base situated at its first end (3), and it has outer annular ribs (13, 14, 17) at each end and in the middle, one or more of which can be toothed.
