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.

Spinal implant and cutting tool preparation accessory for mounting the implant

A spinal cage implant ( ) is adapted to be inserted in a damaged intervertebral disc for restoring the discal height and permitting an arthoesis. Implant ( ) comprises a central part ( ) with walls ( ) and terminal parts ( ) for bearing against the cortical bone ( ) of the vertebral end plates ( ). Central part ( ) is adapted to penetrate the vertebral end plates ( ) and transversely projects from the terminal bearing parts ( ). Implant ( ) bears against the vertebral end plates ( ) with terminal parts ( ) and contains bone graft material between walls ( ) which penetrate the openings ( ) in the end plates ( ) and permit bone fusion between the two vertebrae (V , V ). Implant ( ) permits restoring the physiological lordosis and the intervertebral height
