ABSTRACT:
A space holder in particular for a vertebra or an intervertebral disk is provided. The space holder comprises a jacket (1) having apertures (9, 10) and a first and second edge (7, 8). The edge has circumferentially adjacent recesses (9, 10; 9', 10') each extending in direction towards the other edge and a stop provided at at least one of the edges spaced from the outer edge. In order to provide for an easy manufacture and operation of the space holder the stop is formed by a member (11, 13, 16, 22) having an outer contour corresponding to the inner contour of the jacket (1) and nose-like projections (15) for engaging the recesses (9, 10) are provided at those locations of the periphery of the stop which correspond to the recesses (9, 10; 9', 10').
