A precisely size matched intervertebral plate and spacer
assembly for ensuring a tight fit within a
disc space to promote
spinal fusion, comprising: a “U-shaped” spacer configured to fit within the
intervertebral space; and, a matching countersunk low profile “H-shaped”
anterior plate joined perpendicularly to the spacer. The plate further comprises: a plurality of anchor members configured to attach to the junctions of the anterior cortex faces and the endplates; and, channels individually traversing through the anchor members for inserting screws into the vertebral bodies'
cortical bone. The spacer comprises a hollow three-sided U-shaped member, comprising two opposing parallel side walls, and a perpendicular
posterior wall, while lacking a superior, inferior, and
anterior wall. The exterior walls of the plate and spacer are planar, while the interior walls of the spacer are curved to house a precisely fitting cylindrical graft, or other insert such as
DBM,
bone dust,
bone paste, bone
dowel with direct contact to the endplates to promote fusion.
