Abstract
An expandable intervertebral cage includes a base with a circumferential side wall extending in a first direction and a first bone interaction surface and a stage including a second bone interaction surface arranged essentially opposite to the first bone interaction surface with respect to the expandable intervertebral cage. An expansion mechanism serves for adjusting the position of the second bone interaction surface of the stage with respect to the first bone interaction surface of the base at least in the first direction (z). The expansion mechanism is thereby arranged at least partially within the circumferential side wall of the base.
