40 year old. male with history of falling off a truck while doing some work had complained of low back pain, muscle spasm, hand and feet numbness, and neck pain since the time of the action. Patient underwent C5-6 and C6-7 anterior cervical discectomy with fusion using anterior plating.

	Lateral film showing the intact plate and screws for the fusion and nearly imperceptible grafting material in the disc spaces of C5-6 and C6-7.
	Lateral radiograph taken six weeks later on routine follow-up demonstrates loosening of the  superior anterior screws and ventral displacement of the proximal anterior plate. Early incorporation of grafting material can be seen at the disc spaces. Click on the images to view a larger version!
