Abstract
Abstract An implantation apparatus for preparing adjacent vertebral bodies to receive an intervertebral implant including a plurality of keels. The implantation apparatus includes an elongated handle portion, and a template portion carried at a distal end of the handle portion substantially perpendicularly to the handle portion. The template portion defines a plurality of open channels corresponding in position and shape of the plurality of keels. Each channel is positioned and shaped for preparing a vertebral opening to receive a corresponding keel.
