Abstract: An interspinous stabilization system comprising three elements and characterized in that two of its elements, called spinous anchoring parts (1, 3), are fastened to the superior and inferior spinous processes, and the third element, called an intermediate part (2), is interposed between the other two in order to ensure distraction of the interspinous space and movability of the device in the three spatial planes.

Abstract: A consolidation rod and plural members, such as pedicular screws and vertebral claws, have threaded sections extending from a head and fitted with a nut. A rigid fast connection between the rod and a member providing high adhesion is ensured by a fastener for clamping the rod owing to the screwing of the nut. The fastener comprises a first bore sliding on the rod, a slit opening into the first bore and narrowed by nut screwing, and a second bore passing through the slit and passed through by the threaded section. An indented plate, or a bar with threaded ends fitted with hooks transversely stabilizes two consolidation rods. A connector longitudinally stabilizes two consolidation rods.
