The device ( 4 ) comprises two vertebral elements ( 10, 20 ) each adapted to be fixed to the same lateral side of the body of at least two adjacent vertebrae ( 1, 2 ). In order to guide the vertebrae effectively and stably in order to reproduce an articulating intervertebral joint, the elements delimit respective surfaces ( 14 A, 26 A) for the relative guiding of the two elements, which surfaces are so adapted that, when the elements are implanted on the corresponding vertebrae, they cooperate with one another by complementarity of forms, in such a manner that they define an axis of rotation (X-X) about which the two elements are able to tilt one relative to the other and which extends both according to a direction substantially mediolateral to the spine and in the intervertebral disk space ( 7 ) separating the two adjacent vertebrae.
