Abstract
This invention comprises a device and a method of maintaining spinal exposure, distraction, alignment and temporary fixation. Additionally provided for, is tooling guidance for the preparation of an intervertebral space for an implant. The device provides a means for attaching a tube or other attachment to guide tools that will prepare the vertebrae for accepting an implant. At any time during the procedure the attachment may be removed to inspect or remove debris from the disc space and the vertebral end plates without disturbing the distraction and temporary fixation.
