Title (EN) INTERVERTEBRAL IMPLANT
(FR) IMPLANT INTERVERTEBRAL
(DE) ZWISCHENWIRBELIMPLANTAT
Abstract:
(EN) The invention relates to an intervertebral implant comprising a three-dimensional body (10) comprising an upper side (1) and a lower side (2), which can be placed on two end plates of two adjacent vertebral bodies. Said implant also comprises a left side surface (3) and a right side surface (4), a front surface (5) and a rear surface (6), a horizontal middle plane (7) arranged between the upper side (1) and the lower side (2), a vertical middle plane (12) extending from the front surface (5) to the rear surface (6), and a plurality of bores (9) extending through the body (10). Said bores can be used for receiving longitudinal fixing elements (20). The three-dimensional body (10) comprises a front plate (8) on the front surface (5) thereof, extending through the bores (9) and wherein the longitudinal fixing elements (20) are anchored. The intervertebral implant also comprises a securing plate (18) which can be fixed to the body or to the front plate in an essentially parallel manner on the front plate (8) in such a manner that the bores (9) are at least partially covered by the security plate (18). A durable and rigid, i.e. solid connection is thus possible between the intervertebral implant and the longitudinal fixing elements used for the fixing thereof.
(FR) L'invention concerne un implant intervertébral pourvu d'un corps tridimensionnel (10) présentant une face supérieure (1) et une face inférieure (2), prévues pour reposer contre les plaques d'extrémité de deux corps vertébraux adjacents, une face latérale gauche (3) et une face latérale droite (4), une face avant (5) et une face arrière (6), un plan médian horizontal (7) situé entre la face supérieure (1) et la face inférieure (2), un plan médian vertical (12), s'étendant de la face avant (5) à la face arrière (6), ainsi qu'une pluralité d'alésages (9) pénétrant le corps (10), lesquels alésages sont prévus pour recevoir des éléments de fixation longitudinaux (20), ledit corps tridimensionnel (10) présentant, sur sa face avant (5), une plaque avant (8) traversée par les alésages (9) et dans laquelle les éléments de fixation longitudinaux (20) peuvent être ancrés. Cet implant intervertébral comporte également une plaque d'arrêt (18), qui peut être fixée au corps (10) ou à la plaque avant (8) de façon sensiblement parallèle à cette plaque avant (8), de sorte que les alésages (9) peuvent être au moins partiellement recouverts par la plaque d'arrêt (18). Ainsi, une liaison durable et rigide, c.-à-d. solide, entre l'implant intervertébral et les éléments de fixation longitudinaux utilisés pour sa fixation peut être obtenue.
(DE) Das Zwischenwirbelimplantat umfasst einen dreidimensionalen Körper (10) mit einer Oberseite (1) und einer Unterseite (2), welche zur Anlage an die Endplatten zweier benachbarter Wirbelkörper geeignet sind, einer linken Seitenfläche (3) und einer rechten Seitenfläche (4), einer Vorderfläche (5) und einer Hinterfläche (6), einer zwischen der Oberseite (1) und Unterseite (2) liegenden, horizontalen Mittelebene (7), einer von der Vorderfläche (5) zur Hinterfläche (6) verlaufenden vertikalen Mittelebene (12) sowie einer Mehrzahl den Körper (10) durchdringenden Bohrungen (9), die zur Aufnahme von longitudinalen Fixationselementen (20) geeignet sind; wobei der dreidimensionale Körper (10) an seiner Vorderfläche (5) eine Frontplatte (8) aufweist, durch welche die Bohrungen (9) hindurchgehen und in welcher die longitudinalen Fixationselemente (20) verankerbar sind. Das Zwischenwirbelimplantat weist weiter eine Sicherungsplatte (18) auf, welche im wesentlichen parallel zur Frontplatte (8) am Körper (10) oder an der Frontplatte (8) derart befestigbar ist, dass die Bohrungen (9) mindestens teilweise von der Sicherungsplatte (18) abdeckbar sind. Dadurch ist eine dauerhaft rigide, d.h. feste Verbindung zwischen dem Zwischenwirbelimplantat und den zu seiner Befestigung verwendeten longitudinalen Fixationselementen möglich.
