The invention shows an intervertebral disc replacement for the core of an intervertebral disc, which consists of a flat spiral (2) made of plastic, which can be elongated with auxiliary tools and which automatically winds up to its spiral shape in the force-free state. The spiral (2) is connected along its wound body (3, 4, 5) on the top or bottom (18, 19) to one or more bodies (9, 10, 11) made of a hydrogel, which by the absorption of Water increase its volume and protrude above the top (18) or bottom (19) of the spiral (2). |
