CERVICAL PROSTHESIS AND INSTRUMENTS

摘要

The invention relates to a cervical prosthesis comprising a lower cover plate (10), which is to be connected to a lower vertebral body, an upper cover plate (11) which is to be connected to an upper vertebral body, and a prosthesis core (12) which forms an articulated connection between the upper and the lower cover plate. The lower surface of the cover plate (10) is essentially flat. The surface (14) of the upper cover plate (11) is convex at least in the sagittal section.
