Abstract
The invention concerns an implant comprising a body with an upper surface and a lower surface capable of pressing on the vertebral end-plate located immediately above and beneath and having further at least a through aperture emerging on the upper and lower surfaces. The invention is characterized in that the implant further comprises an anchoring member mounted in such a way as to be capable of moving in the aperture. The said anchoring member includes a support part adjacent to a first vertebral end-plate, and at least a projecting anchoring element extending from the support part towards the opposite vertebral end-plate. Thus, when the implant is compressed between the vertebral end-plates, the anchoring member is stressed by the first vertebral end-plate at the support part to move relative to the body and the at least providing projecting element overlaps the body surface facing the opposite vertebral end-plate and is anchored therein. The invention is particularly applicable to bone fusion between cervical vertebrae.
