Abstract
A spinal implant for insertion in the intervertebral space is formed as a hollow cage, wedge shaped in profile, with a lesser height leading end for a low profile entry. The cage has two open sides with a plurality of angled teeth along opposite longitudinal edges for engaging the end plates of adjacent vertebrae when the cage is rotated into position. One portion of the angled teeth is angled toward an end of the cage and another portion of the angled teeth is angled away from that end to provide a lock preventing the cage from migrating ventrally or dorsally from the spine. Upon rotation, the leading end has a greater height than the trailing end. Opposing side walls of the cage include recesses to facilitate rotation of the cage and minimize stress on adjacent vertebrae.
