Intervertebral disc endoprosthesis with two prosthesis plates which are to be connected to the end plates of the relevant vertebrae, and with a prosthesis core which cooperates with at least one prosthesis plate via an articular surface permitting a rotational movement around the vertical axis, In order indeed to make possible a rotational movement around the vertical axis but to oppose this movement by a resistance, the articular surface forms curved arches of different average radius in the median section and in the frontal section. The radius of curvature in the sagittal section is expediently less than in the frontal section. To avoid excessive twisting it is possible to provide stops on the prosthesis plates and on the prosthesis core. These are designed, for example, as ribs and grooves which run in the median plane.
