Abstract
A method of limiting the movability of an intervertebral disk prosthesis with regard to pivoting movements, and an intervertebral disk prosthesis. The method includes the step of asymmetrically limiting at least one of a flexion-extension movement, a lateral bending, and a rotation about a vertical axis in order to limit the movability of the prosthesis. The prosthesis comprises articulated prosthesis components, and movement-limitation measures configured to limit movability of the components with respect to flexion-extension movement, lateral bending and a rotation about a vertical axis of the prosthesis in a defined manner.
