Abstract

An implant (1) including a body (5) receiving a bone graft (2) and having upper and lower (5a) surfaces engageable with the cancellous bone of the vertebral end plates (3a), and at least one side projection (6) with a size substantially equal to the vertebral interspace to be restored, said projection (6) being insertable between the vertebral end plates (3a). The upper and lower (5a) surfaces of the body (5) have a cross-section with a curved outline, and the projection (6) is shaped in such a way that it projects beyond the shell of said body (5).
