Intervertebral fixing and articulated joint comprises plates fastened to surfaces of adjacent vertebrae and mobile element between. The fixing (F), designed to be implanted between two adjacent vertebrae (V1, V2), consists of two rigid plates (10, 11) with holes (15), attached to the facing surfaces of the vertebrae by fastenings (30) such as rods or screws, and at least one intermediate element (20) between them. Each intermediate element contains at least one mobile and/or deformable component (25), e.g. a bellows filled with silicone oil, which provides for a relative displacement of the rigid plates to form an artificial articulated joint and has a viscoelasticity which is preferably variable and especially by remote control. The fastenings are of greater length than the axial dimension between the vertebrae and are made in linked sections, especially clipping together. The plates and intermediate elements are made e.g. from titanium or stainless steel.
