APPARATUS AND METHOD FOR ANTERIOR INTERVERTEBRAL SPINAL FIXATION AND FUSION

摘要

A method of using a plurality of blades within a fixation device to attach to a vertebra is provided. Each blade includes a body having a central opening configured to rotate on a shaft within a 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 the 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.
