Abstract

Un implant intervertébral en forme de cylindre creux, présentant un axe longitudinal (3), une surface supérieure (1) et une surface inférieure (2), est constitué principalement d'un matériau céramique ayant une porosité maximum de 30 % en volume et comportant des pores remplis d'air. L'implant est caractérisé par le fait qu'après la fusion primaire, il compense la distance (correspondant à la hauteur du disque) entre les deux corps vertébraux pendant le processus de résorption - s'accompagnant d'une fusion adéquate - et, qu'après un certain temps, il est résorbé par lesdits corps vertébraux.
