<p>The invention relates to an intervertebral prosthesis, in particular for the cervical spine, comprising two articulated connection plates. The connection surfaces of the connection plates, which can be connected to the adjacent vertebral body, comprise a base surface (3) which is to be applied to the surface of the vertebral body and comprises self-tapping fixing projections which can be raised therefrom. According to the invention, the self-tapping fixing projections are formed from at least one pair of ribs (4), which extend in the opposite direction, diagonal to the predetermined direction of implantation (2) and the lateral surfaces (5) thereof which are used counter to the direction of implantation are steeper than the lateral surfaces (6) thereof used in the direction of implantation (6). The ribs can be toothed.</p> |
