Abstract
With the invention, tubular support bodies for bridging two adjacent vertebrae are shown. Two cages (1, 2) which are placed one within the other are provided with cut-outs, and each of them has a support flange (5) at the outer end face (6). A first cage (1) has at least three radially projecting protrusions (7) at its jacket (9a) which can be introduced into three axially extending lead-in channels (8) or a multiple thereof in the jacket (9b) of the other cage (2) in order to be able to reach latch-in positions (10, 11, 12) of different depths.
