摘要： An intervertebral prosthesis, in particular for the cervical spine, includes a first cover plate to be connected to a first vertebral body, second cover plate to be connected to the second vertebral body, and a prosthesis core which forms an articulation with the second cover plate. The prosthesis core is held by seat of the first cover plate which is designed as a guide device. The core can be pushed into the guide device from the ventral side in the anterior-posterior (AP) direction relative to the first cover plate. A limit-stop plate is provided on the ventral edge of the first cover plate. This limit-stop plate is displaceable in a slide guide between a locking position and a nonlocking position.
