Abstract
The device (9) comprises vertebral elements (10, 20, 10′, 20′) adapted to be fixed to the same lateral side of the bodies of at least two adjacent vertebrae (1, 2), the elements being associated in pairs that are provided to be associated with the left and right sides of the vertebrae. In order to guide the vertebrae effectively and stably, in order, in use, to reproduce an articulating intervertebral joint, the two elements of each pair delimit respective surfaces (15, 25, 15′, 25′) for the relative guiding of those elements, which surfaces are adapted, when the elements are implanted on their corresponding vertebra, to extend generally along the same lateral side of the body of the vertebrae and to rest and slide one against the other in such a manner that the surfaces define a center of rotation (C) about which the two elements are able to turn one relative to the other.
