Method to supplement or replace a core pulposo located in a central region of a fibrous annulus of an intervertebral disc, the body of hydrogel solid elongated fully hydrated physiologically, instrument to insert a body of hydrogel is elongated in a central region of a sta El fibrous, methods to moisturize a hydrogel and to prepare a prosthesis, and.The prosthesis core pulposo of an intervertebral disc is supplemented or replaced by a prosthesis of hydrogel is elongated, fully hydrated physiologically, inserted in the central region of an intervertebral disc, where it can bend back on itself, forming a body of the prosthesis inside D The central region of the fibrous ring.The prosthesis may be expanded hydrogel portions that contribute to prevent expulsion of the prosthesis through the insertion aperture. A tool to insert the prosthesis has a cutter for separating the elongated prosthesis within the central region of the intervertebral disc the After a sufficient quantity have been established.
