An intervertebral prosthesis is disclosed for utilisation as an intervertebral disc replacement in the skeleton of the human body. The intervertebral prosthesis includes a first prosthesis plate, on which is formed a first coupling element, e.g., in the form of a spherical cap, and a second prosthesis plate, in which, for example, a hollow spherical shell is formed, into which, in the coupled state, the spherical cap engages. To create a physiologically favourable intervertebral disc replacement, the rotational movement of both prosthesis plates with respect to each other around an axis perpendicular to the prosthesis plates is significantly limited, for example to 3 degrees. The limitation of the rotational movement is produced by means of a movement restriction means in the form of mechanical blocks on the coupling elements.
