Abstract
This invention comprises a device and a method of maintaining distraction and providing tool guidance in the preparation of an intervertebral space for an implant. It provides a means for attaching a tube, to guide tools that will prepare the vertebra for accepting an implant. At any time during the procedure the tube may be removed to inspect or remove debris from the disc space and the vertebral end plates without disturbing the distraction. The system has multiple tube diameters which can be attached to a common flange to increase the dowel size during the procedure without redistracting.
