Abstract: A spinal fixation device having a spacer member and a pair of fixation plate members, where the spacer member is a cage-like structure having a generally open and exposed interior defined by a pair of superior-inferior bores intersecting a lateral bore, the spacer member having a pair of opposing, generally planar, contact surface members having a plurality of anterior-posterior oriented, beveled ridges disposed thereon, with the fixation plate members attached to the anterior of the spacer member, the fixation plate members being asymmetrical and each containing a generally circular and a slotted screw-retaining aperture, with each disposed to one side of a lateral midline in reversed manner relative to each fixation plate member.
