Osteosynthesis device for spinal consolidation

摘要

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.
