Implantable biomaterials, particularly hydrogel substrates with porous surfaces, and methods for enhancing the compatibility of biomaterials with living tissue, and for causing physical attachment between biomaterials and living tissues are provided. Also provided are implants suitable for load- bearing surfaces in hard tissue repair, replacement, or augmentation, and to methods of their use. One embodiment of the invention relates to an implantable spinal disc prosthesis.

L'invention concerne des biomatériaux implantables, en particulier des substrats d'hydrogel à surfaces poreuses, et des procédés permettant d'améliorer la compatibilité des biomatériaux avec du tissu vivant, entraînant l'adhésion physique entre biomatériaux et tissu vivant. L'invention concerne également des implants appropriés à des surfaces porteuses de charge utilisables dans la réparation de tissu dur, ou bien le remplacement ou l'augmentation de ce tissu, y compris des procédés d'utilisation correspondants. Selon une variante, l'invention concerne des prothèses de disque spinal implantables.
