Tables
Points Spacer margins 0 Any evidence of subsidence or lucency around the cage 1 Tightly marginated with both endplates without bone resorption or subsidence Bone within cage 0 Lucency within cage similar to nonossified disc 1 Increased density within spacer beyond that of nonossified disc space suggestive of trabecular bone Bone bridge 0 No bony bridging between endplates between endplates 1 < 0.5 cm bridge on either sagittal or coronal reconstruction 2 ≥ 0.5 cm bridge on either sagittal or coronal reconstruction Maximum score = 4.
