Abstract: This invention relates to a spinal implant for promoting fusion of adjacent vertebrae and restoration of normal disc height. The spinal implant includes an upper and lower surface adapted to engage cancellous bone tissue in the vertebral bodies. The spinal implant also includes at least two opposing bearing surfaces adapted to bear against cortical bone tissue in the endplates of adjacent vertebrae. This invention also provides an instrumentation to prepare the intervertebral space to receive the spinal implant and techniques for treating patents in need of corrective spinal surgery.

Abstract: A connector (1) for a spinal osteosynthesis device, for connecting two rods to a plate fixed in a vertebra, includes a first orifice (2) opening onto two opposed faces (3, 4) of the connector (1), and two other orifices (5, 6) opening onto two other opposed faces (7, 8) of the connector (1). Each of the two other orifices (5, 6) are each designed to receive a rod (14, 15) of the osteosynthesis device. The connector (1) includes a mechanism making it possible, when the connector (1) is push-fitted onto a protrusion (100) of a bone anchor member, to tighten the rods (14, 15) simultaneously in the two other orifices (5, 6) when a nut (22) is screwed onto the protrusion (100). An assembly for spinal osteosynthesis device includes a plate (16) that includes a protrusion (100), a connector (1) as previously described, and a nut (22).

Abstract: A spinal cage implant is adapted to be inserted in a damaged intervertebral disc for restoring the discal height and permitting an arthoesis. The implant comprises a central part with walls and terminal parts for bearing against the cortical bone of the vertebral end plates. The implant bears against the vertebral end plates with terminal parts and contains bone graft material between walls with an opening to permit bone fusion between the two vertebrae. The implant permits restoring the physiological lordosis and the intervertebral height.

Abstract: Tools and methods for spinal fusion are provided. The tool is configured to cut openings into first and second vertebrae to receive a spinal implant between the vertebrae. The tool includes a proximal handle connected to an elongate shaft that extends to a distal end. The distal end includes a first non-cutting portion through which the shaft extends, a cutting portion fixed to the shaft to rotate with rotation of the shaft, and a second non-cutting portion fixed to the cutting portion.

Abstract: Anchoring plate for a device for osteosynthesis of the vertebral column, including means for connecting it to one or more rods or to a plate. Its lower face is configured to match the shape of a contact zone situated to straddle two vertebrae, and it has openings for the passage of screws. The device for osteosynthesis of the vertebral column includes one or more rods or plates connected to vertebrae by way of connectors and anchoring plates. At least one of the anchoring plates is of the above type described above.

Abstract: A spinal cage implant (1) is adapted to be inserted in a damaged intervertebral disc for restoring the discal height and permitting an arthrodesis. Implant (1) comprises a central part (3c) with walls (4) and terminal parts (5, 6) for bearing against the cortical bone (14) of the vertebral end plates (15, 16). Central part (3c) is adapted to penetrate the vertebral end plates (15, 16) and transversely projects from the terminal bearing parts (5, 6). Implant (1) bears against the vertebral end plates (15, 16) with terminal parts (5, 6) and contains bone graft material between walls (4) which penetrate the openings (19, 21) in the end plates (15, 16) and permit bone fusion between the two vertebrae (V1, V2). Implant (1) permits restoring the physiological lordosis and the intervertebral height.

Abstract: This instrumentation comprises at least one vertebral rod (1), bone anchoring elements (2) spaced along the rod, a connector (3) connecting the rod to each anchoring element, and pressure means (4) for clamping together the rod, the anchoring element and the connector; each anchoring element has a bearing surface (7) for the rod which is inclined relative to the longitudinal axis (XX) of the anchoring element; in the connector there is provided a cavity (11) providing at least one bearing point for the rod held trapped between said inclined bearing surface and a wall (12) of the cavity, and the latter is extended by a lateral aperture (18) permitting insertion of the vertebral rod radially in its cavity; this instrumentation is easy to use by the surgeon owing to the convenience of insertion of the rod in the connector, and the direct bearing of the rod against the surface (7) of the anchoring element (2) reduces its transverse overall size.
