Abstract: The present invention concerns an accessory for tensioning an elongate element for attaching an implant to a bone element, comprising a rod having proximal and distal ends and a longitudinal axis L, the distal end of said rod being provided with a bearing device for bearing on the implant. The accessory further comprises a device for tensioning the elongate element, comprising a drum mounted so as to be able to rotate about an axis T, transverse to the axis L, arranged at the proximal end of the rod, the drum comprising a holding portion suitable for cooperating with the elongate element. The tensioning device comprises a device for rotating the drum about the axis T, allowing the elongate element to be tensioned by winding the elongate element around the drum.

Abstract: A vertebral support for positioning between the laminae of the vertebrae. The support may comprise an anterior portion inserted between the laminae of the vertebrae, suitable for giving an anatomical intervertebral spacing, and a posterior portion providing mobility in the region fitted with the implant. A retaining member may limit displacement of the support by shoulders projecting from the anterior portion of the support, and by two transverse projections.

Abstract: A method for repairing bone in a bone cavity delimited by healthy bone faces, and from which traumatized bone has been excised, comprises adjusting a flexible, biocompatible mesh fabric tube to fit the bone cavity and contact the healthy bone faces and filling the mesh tube with a bone graft. A bioresorbable coating is applied to the tube to rigidify the tube having been adjusted in shape to fit the bone cavity. The coating seals the mesh against graft movement through the mesh of the tube until the bioresorbable coating has been resorbed. The tube is inserted within the bone cavity and the coating is resorbed to allow the graft to pass from the interior of the tube, through the mesh, to the healthy bone faces.

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 serrations (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.
