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.
