The invention relates to an intervertebral disc prosthesis (1) having at least one upper plateau (4, 4') and at least one lower plateau (5, 5'), which are separated by two movable cores (6, 6') whose lower face (62, 62') and upper face (61, 61') respectively match a concave surface (54, 54') of the upper plateau (4, 4') and a convex surface (44, 44') of the lower plateau (5, 5'). The invention also relates to an intervertebral prosthetic unit (10) having an intervertebral disc prosthesis and a posterior articular prosthesis (11) provided with two adjacent and partially tangent articular blades (12, 13), which are each coupled to a vertebra (3, 3') by coupling means (14) and are connected by guide means that allow them to move along a curve whose centre C3 is provided on the same side as the implantation of said coupling means (14).
