<p>A consolidation rod (1a) and several elements, such as peduncle screws (2) and vertebral claws (4) have threaded segments (22; 41) extending from a head (23; 43) and fitted with a nut (24). A rigid quick-attachment connection between the rod and an element (2; 4) giving high cohesion is provided by a clip for clamping the rod (1a) following the screwing of the nut (24). The clip includes a smooth bore sliding on the rod, a first slot emerging in this bore and compressed by screwing the nut, a bore passing through the slot and passed through by the threaded segment and a second slot, perpendicular to the first slot. A rivet plate (60) or a bar (702) with threaded ends, fitted with hooks (71) transversely stabilises two rods (1a, 1b). A connector (8) stabilises two rods (1a, 1c) longitudinally. <IMAGE></p> |
