Abstract

The invention relates to an artificial intervertebral disc for implanting between two vertebral bodies (W) comprising two end plates (1, 2) which bound a hollow space (4), which is filled with an elastically and/or plastically deformable nucleus (3), at two opposite sides, with the hollow space (4) being enclosed by a tubular fiber ring (5) such that the end plates (1, 2), together with the fiber ring (5), bound the hollow space (4) and the end plates (1, 2) are in tensile connection with the fiber ring (5). The fiber ring (5) is designed as elastically extensible in the radial and axial directions, with the fiber ring (5) having a larger modulus of elasticity than the nucleus (3) and the nucleus (3) and the fiber ring (5) interacting such that the elastic properties of the artificial intervertebral disc show a non-linear behavior with increasing deformation at least with respect to a compression force (F).
