Abstract

An implant assembly for a spinal column includes at least a plate and an interbody implant attached to the plate. The interbody implant is positioned in the spinal disc space and the plate extends extradiscally for attachment to the first and second vertebrae outside the disc space. The assembly may include recesses in the bottom surface of the plate, spacers, and spacing portions extending from the bottom surface of the plate that allow the plate to be secured to the interbody implant when the trailing end of the interbody implant is positioned in a recessed, flush or overhanging position relative to the laterally facing surfaces of the vertebrae.
