Abstract: A spinal osteosynthesis system, in particular for anterior spinal fixation, comprising at least an anchoring member, an elongated linking element and a connector capable of being fixed to the anchoring member and to the linking element by selecting an angular position of the linking element relative to the connector. The system comprises a second elongated linking element, the connector being capable of being fixed simultaneously to both linking elements.

Abstract: Implant for the cervical spine comprising an anterior plate (1) for maintaining a bone graft, bone anchorage screws (6, 7, 8) for the plate and at least one slide (22) for blocking the screws and preventing any migration of the screws, characterized in that the at least one slide (22) is slidably mounted on the plate so as to be applicable on at least one anchorage screw head (15, 16). The slide cooperates with boss and recess portions for retaining the slide on the head of the screw. The slide may be formed by a thin platelet (22a)) which is provided with lateral flanges (25) and is slidable in a complementary cavity (18) provided in the plate (1) while being flush with the surface of the plate (1). The plate (1) includes ramps (26) for retaining the slide (22) on which the flanges (25) are slidable, the slide (22) being slidable to a position in which it at least partly overlaps the heads of the associated screws (6 or 7) and is locked in position by suitable structure.

Abstract: The invention concerns a backbone osteosynthesis system, in particular for anterior fixing comprising: an elongated linking element; a vertebral screw with a threaded head; a connector comprising two branches capable of being engaged onto the screw and clamping between them the linking element; and a threaded clamping member capable of co-operating with the head for clamping the branches. The head has a threaded orifice, the clamping member comprising a threaded rod capable of being urged to be engaged in the orifice.

Abstract: The invention concerns a backbone osteosynthesis system comprising an elongated element , a vertebral screw, and a connecting element comprising two branches for clamping between them the linking element, at least one first branch being capable of being engaged onto the screw. The system comprises a second vertebral screw, the first branch having an extension capable of being engaged onto the second screw. The system may comprise a second elongated linking element.

Abstract: The clamp (1) comprises a pair of hooks (2, 3) adapted to bear on at least two cervical vertebrae (for example C1, C2) and each having a tubular portion (6, 7). The diameters of the latter are such as to permit the fitting and the sliding of one portion in the other and consequently the adjustment of the relative position of the two hooks. They are fixed in this position by a permanent deformation of the walls of the tubular portions (6, 7) by a suitable ancillary tool. The clamp provides better stability than known devices, since the two hooks (2, 3) of the clamp cannot move apart owing to their interconnection by deformation of material which clamps them in position relative to each other and avoids the use of components such as nuts and screws. Further, this clamp is small in size and is placed in position by the surgeon in a particularly simply manner.
