Title (EN) ELASTOMERIC INTERVERTEBRAL DISC PROSTHESIS
(FR) PROTHESE DE DISQUE INTERVERTEBRAL EN ELASTOMERE
Abstract:
(EN) In an intervertebral disc prostheses having a pair of rigid endplates (101, 102) and an elastomeric core structure (100) between the endplates. In one embodiment, the elastomeric core structure has an anterior-posterior dimensio (307) sufficiently less than that of the endplates, such that the elastomeric core does not protrude beyond the periphery of the endplates during flexion. In another embodiment, the core structure is defined to have an anterior-posterior dimension not greater than three times its axial height dimension (306) . The core structure may comprise two core members having different durometer hardness .
(FR) L'invention concerne une prothèse de disque intervertébral qui comporte deux plaques d'extrémité rigides séparées par une structure de noyau élastomère. La structure du noyau est conçue pour conférer à la prothèse les caractéristiques fonctionnelles recherchées.
