A rigid cage (110) to be introduced into an intervertebral-disc compartment between two adjacent vertebrae is assembled from two constituent elements (110a, 110b) along a jointing face which extends parallel to transverse sides of the cage. According to another embodiment, operating means, for example a pair of rods (231, 233), may be fastened to a cage (210) in order to rotate the cage within the intervertebral-disc compartment. Both approaches make it possible to introduce the cage through an access canal having a very omall diameter. |
