Bone junction device null for vertebral column coherent

摘要

A rod of the consolidation (1a) and a plurality of elements, such as pedicular screws (2) and the claws vertebral (4), have the threaded portions (22, 41) extending from a head (23, 43) and provided with a nut (24). Rapid a rigid connection between the rod and an element (2, 4) offering a high adhesion is ensured by a fastener, in order to grip the upper (1a) after screwing the nut (24). The fastener has a bore to slide on the rod, a slot opening out into this bore and the narrowed by screwing the nut, and a bore passing through the slot and through which the threaded section. A notched plate (60) or a bar with threaded ends (702) provided with hooks (71) stabilises transversely two rods (1a, 1b). A connector (8) stabilises two longitudinal rods (1a, 1c).
