Abstract:
1. An intervertebral disk prosthesis suitable for being put into place between two vertebrae by the posterior technique or by the anterior technique, the prosthesis comprising: a first fixing element having an anchoring first face for anchoring the first fixing element to one of the two vertebrae, and a co-operation second face; a first prosthesis element having an active first face and a co-operation second face, the co-operation faces of the first fixing element and of the first prosthesis element, respectively, being fixed in opposition to each other such that the first fixing element and the first prosthesis element are fixed to one another in a plane substantially orthogonal to the axis of the vertebrae; a second fixing element having an anchoring first face for anchoring the second fixing element to in the other of the two vertebrae and a co-operation second face; and a second prosthesis element having an active first face and a co-operation second face, the co-operation faces of the second fixing element and of the second prosthesis element, respectively, being fixed in opposition to each other such that the second fixing element and the second prosthesis element are fixed to one another in a plane substantially orthogonal to the axis of the vertebrae; wherein the active first face of the first prosthesis element and the active first face of the second prosthesis element are disposed in moveable opposition to each other, one of the active first faces being concave and the other of the active first faces being convex so as to define a spherical cap, wherein the first prosthesis element comprises two distinct parts, each of the two distinct parts comprising the first prosthesis element having respective surfaces arranged so as to collectively define the active first face, wherein the second prosthesis element comprises two distinct parts, each of the two distinct parts comprising second prosthesis element having respective surfaces arranged so as to collectively define the active second face.
