<p>A registration device (100) is used to couple an identification superstructure of a surgical navigation system to the spinal column. The registration device (100) includes a pair of vertebral engaging members (202, 204) positionable in a spinal disc space. At least one of the vertebrae engaging members (202, 204) moves outwardly from a collapsed position to engage the registration device (100) to the endplates of the adjacent vertebrae.</p> |
