The invention relates to an interbody cage, particularly of the TLIF type, characterised by a nut (7) for receiving, in a hole (17) pierced therein, a rod of an insertion device, the nut being received in a cavity (6) formed in the cage, the shape and/or dimension of the cavity and/or the nut being such that the nut can be moved inside the cavity, particularly along an arc of a circle, so as to pass between two relative positions of the cage and the rod rotated in relation to each other and at a distance from each other. |
