Repuesto de disco intervertebral para el núcleo de un disco intervertebral, con una espiral plana (2) de material sintético que puede alargarse de forma oblonga con herramientas auxiliares y que, en estado sin fuerzas, se arrolla automáticamente en su forma de espiral caracterizado porque la espiral (2) presenta, a lo largo de su cuerpo arrollado (3, 4, 5), en su cara superior o inferior (18, 19) uno o varios cuerpos (9, 10, 11) de un hidrogel los cuales, mediante la absorción de agua, aumentan su volumen y sobresalen de la cara superior (18) o de la cara inferior (19) de la espiral (2). Invertibral prothesis, for damaged invertebral disc nucleus, which has a flat spiral of plastics that can be pulled out lengthwise with tools and rewinds automatically to its spiral form in the unstressed state, the spiral has hydrogel structure(s) on the upper or under side, which swell by absorbing water and project from the spiral on the upper or under side.
