Abstract
A rotation-symmetrical articulation chamber is formed in the shaft head of an endoprosthesis. An axial articulation member is disposed in this chamber. The articulation member axis and the axis of rotation are perpendicular relative to each other. A joint neck can be pivoted about the axis of rotation and the articulation member axis at any selected angle of inclination or rotation. Clamping surfaces that are disposed at an angle to the axis of rotation are rotation-symmetrical or planar and interact with articulation surfaces of the articulation member that can also be rotation-symmetrical.
