Apparatus for anterior intervertebral spinal fixation and fusion

A fixation device comprising:

• a housing with a leading deep surface and a trailing outer surface, weight bearing sides, and top and bottom surfaces;
• a shaft running from the leading deep surface to the trailing outer surface of the housing;
• a plurality of blades, each of the blades comprising:
• a body having a central opening configured to rotate on the shaft within the housing of the fixation device;
• control openings on opposing sides of the central opening sized to engage prongs of a rotating tool;
• and
• at least one cutting extension with a sharp leading edge extending from the body in an orientation about an axis of the shaft;
• wherein upon rotation of a blade by the rotating tool about the shaft in a direction in which the at least one cutting extension is oriented, the at least one cutting extension will break an endplate of a vertebra and hook into the vertebra.
