Abstract

A cervical intervertebral disk prosthesis has two cover plates, at least one of which is provided with a wedge-shaped connection surface for connection to a vertebral body and which is wider than it is deep. The dorsal edge of the connection surface may be set back from the dorsolateral edge of the cover plate having the connection surface and be connected to the dorsal edge, protruding above it, via a rounding or bevel.
