Beschreibung
Zusammenfassung:	The nuclear implant according to the present invention consists of a nucleus (10) arranged inside a nuclear space (Es) obtained after nucleotomy of the intervertebral disc (Di) and at least one extension (11) penetrating inside at least one channel (Co) formed in the vertebral body of the corresponding vertebra (Va, Vb) to strengthen and provide a link between the nuclear implant (1) and the bone body of the vertebra (Va) and/or (Vb), by diffusion or migration of the viscoelastic material forming said nuclear implant into the cancellous bone of said vertebra.
