Abstract
A spinal cage implant (1) is adapted to be inserted in a damaged intervertebral disc for restoring the discal height and permitting an arthoesis. 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
