  • Publication number: 20040220571
    Abstract: The present invention is directed to a plating system for anterior fixation of the spine that utilizes a fixation plate. The plating system stabilizes the spine and promotes fusion and incorporation of a graft in a portion of the spinal column. The plating system includes a fixation plate and bone screws that extend through holes in the plate to rigidly secure the plate to vertebrae. The plating system also includes a retainer assembly that prevents screw back out. Methods and instruments relating to the plating system are also described.

  • Publication number: 20040158246
    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 means (22) for blocking the screws and preventing any migration of the screws, characterized in that the blocking means comprises at least one slide (22) slidably mounted on the plate so as to be applicable on at least one anchorage screw head (15, 16). The slide cooperates with means (33, 34) 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 means.

  • Patent number: 6749612
    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.

  • Patent number: 5620444
    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.
