The invention concerns an implant comprising a body (10) with an upper surface (14) and a lower surface (13) capable of pressing on the vertebral end-plate located immediately above and beneath and having further at least a through aperture (11) emerging on said upper and lower surfaces. The invention is characterised in that the implant further comprises an anchoring member (20) mounted in such a way as to be capable of moving in said aperture, said anchoring member comprising a support part (22) adjacent to a first vertebral end-plate, and at least a projecting anchoring element (21) extending from said support part towards the opposite vertebral end-plate, such that when the implant is compressed between the vertebral end-plates, said anchoring member (20) is stressed by the first vertebral end-plate at said support part to be mobile relative to the body and said at least provided projecting element (21) 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.
Un implant comprend un corps (10) possédant une face supérieure (14) et une face inférieure (13) aptes à s'appuyer sur les plateaux vertébraux sus- et sous-jacents et possédant en outre au moins une ouverture traversante (11) débouchant sur lesdites faces supérieure et inférieure. Selon l'invention, l'implant comprend en outre un organe d'ancrage (20) monté de façon à pouvoir se déplacer dans ladite ouverture, ledit organe d'ancrage comprenant une partie d'appui (22) adjacente à un premier plateau vertébral, et au moins un élément saillant d'ancrage (21) s'étendant à partir de ladite partie d'appui en direction du plateau vertébral opposé, de telle sorte que lorsque l'implant est comprimé entre les plateaux vertébraux, ledit organe d'ancrage (20) soit sollicité par le premier plateau vertébral au niveau de ladite partie d'appui pour se déplacer par rapport au corps et pour que ledit élément saillant (21) au moins prévu déborde de la face du corps tournée vers le plateau vertébral opposé et s'ancre dans ce dernier. Application notamment à la fusion osseuse entre plateaux vertébraux cervicaux.
