ABSTRACT:
A multi-part intervertebral endoprosthesis includes a top closure plate, a bottom closure plate, a sliding core between the closure plates, each closure plate having a pair of receiving openings or projections, and an insertion instrument which has a handgrip area and a gripping area with retention projections or openings which, in order to hold the intervertebral endoprosthesis on the insertion instrument, can be engaged in the receiving openings or projections. The receiving openings are arranged in lateral side faces of the intervertebral endoprosthesis, and at least the pair of receiving openings on one of the closure plates has an extended shape extending in the direction toward the other closure plate. In this way, without making changes to the insertion instrument, intervertebral endoprostheses with sliding cores of different thicknesses can be held securely and with the guarantee that they are correct positioned within the insertion instrument.
