Publication number: 20140194994Abstract: The present invention provides an intervertebral implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine. The implant includes a spacer portion having an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole extending through the spacer body. The present invention further provides screw holes extending from a side portion to the inferior and superior surfaces of the spacer portion and a plate portion coupled to the spacer portion through a coupling means, wherein the plate portion contains screws holes for receiving screws. A screw back out prevention mechanism adapted on the plate portion and prevents the back out of screws from the screw holes.Type: ApplicationFiled: March 13, 2014Publication date: July 10, 2014Applicant: Globus Medical, Inc.Inventors: William E. Duffield, Colm McLaughlin, Jason Gray, Jamie Carroll, Mark Adams, William S. Rhoda
