Title (EN) TWO-PART INTERSOMATIC IMPLANT
(FR) IMPLANTS INTERSOMATIQUES EN DEUX PARTIES
Abstract:
(EN) The invention concerns an implant for backbone surgery essentially comprising a hollow body (10) to be inserted in an intervertrebral space, said body having a pair of lateral walls (102, 103) enclosing an internal space exposed to the superjacent and subjacent vertebrae defining said intervertebral space. The implant further comprises an anchoring reinforcement member (20) having on its outer surface bone anchoring projections (22) inscribed in a diameter greater than the body overall height, said member being driven in rotation in the inner space of the body. The invention concerns various improvements to such a two-part implant.
(FR) Un implant pour la chirurgie du rachis comprend un corps (10) essentiellement creux apte à être inséré dans un espace intervertébral, ledit corps possédant une paire de parois latérales (102, 103) entourant un espace intérieur exposé aux vertèbres sus- et sous-jacentes qui définissent ledit espace intervertébral. L'implant comprend en outre un organe de renforcement d'ancrage (20) possédant sur sa surface extérieure des saillies (22) d'ancrage osseux inscrites dans un diamètre supérieur à la hauteur hors-tout du corps, ledit organe étant apte à être entraîné en rotation dans l'espace intérieur du corps. L'invention propose différents perfectionnements à un tel implant en deux parties.
