ABSTRACT:
A flanged interbody spinal fusion implant for insertion at least in part between adjacent vertebral bodies has opposed upper and lower surfaces adapted to contact each of the adjacent vertebral bodies from within the disc space, a leading end for insertion between the adjacent vertebral bodies, and a trailing end opposite the leading end. The trailing end has a height greater than the maximum height of the disc space forming a flanged portion adapted to overlie a part of the anterior aspects of the vertebral bodies adjacent and proximate the disc space to be fused. The flanged portion has at least two bone screw receiving holes, at least one each adapted to overlie each of the adjacent vertebral bodies at least in part. The implant has at least one locking element to lock one or more of the bone screws inserted in the bone screw receiving holes. Instrumentation for inserting the implant, forming screw holes in the vertebral body, and for locking the locking elements are disclosed.
