Graft Reabsorption

61 y.o male, s/p c4-5 discectomy and interbody fusion for myelopathy.

	Initial post-operative films show bone graft intact, with mildly prominent pervertebral soft tissues, as expected in the immediate post-operative period.
	8 months later, the follow-up films demonstrate lucency at the graft site worrisome for resorption. Figure _. Axial CT examination, without contrast.
