  • Publication number: 20090164015
    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.

  • Patent number: 7465305
    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.

  • Publication number: 20070010885
    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.

  • Publication number: 20040204714
    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.
