Abstract

L'invention concerne une endoprothèse de disque intervertébral à implanter dans la colonne vertébrale. L'endoprothèse selon l'invention comprend une plaque d'extrémité supérieure (1) et une plaque d'extrémité inférieure (2) à fixer respectivement à l'os des corps vertébraux, ainsi qu'un palier lisse placé entre les plaques d'extrémité (1, 2) et constitué de corps de glissement (3, 4) qui glissent l'un sur l'autre. Les deux plaques d'extrémité (1, 2) sont en plastique et les corps de glissement (3, 4) sont en céramique, les corps de glissement (3, 4) étant enrobés par le plastique des plaques d'extrémité (1, 2) et les zones de surface des corps de glissement (3, 4) enrobées du plastique des plaques d'extrémité (1, 2) présentant des augmentations de surface par rapport à des surfaces planes. Pour que les corps de glissement soient reliés de manière fixe et bloquée en rotation aux plaques d'extrémité, les augmentations de surface sont des bosses (6) ou des creux sur les corps de glissement (3, 4).
