  • Patent number: 5487743
    Abstract: The instrumentation comprises a pair of vertebral implants (1) provided with screws (4) for anchorage to two corresponding vertebrae located on each side of a damaged vertebra, and a plate (3) having two end portions (3a) for connection to the two implants, and equipped with serration (6, 15) for fixing it to the implants. The end portions (3a) of the plate have a rounded periphery and the instrumentation comprises fixing screws (50) having heads (51) which are rounded so that their surface is flush with the surface of the plate when they are anchored in the apertures of the implant and the apertures of the end portion (3a) of the plate. This arrangement ensures that the ends of the plate (3) do not come into contact with the vertebral discs when the angular position of the plate (3) relative to the implants varies, and reduces the overall size of the instrumentation.
