Zusammenfassung:	A nucleus implant includes a core (10) arranged inside a nucleus pulposus space (Es) obtained after nucleotomy of the intervertebral disk (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 ensure a connection between the nucleus implant (1) and the bone body of the vertebra (Va) and/or (Vb) through the diffusion or migration of the viscoelastic material making up the nucleus implant in the cancellous bone of the vertebra.
