Spinal Diseases

	Intervertebral Disk Displacement - An intervertebral disk in which the nucleus pulposus has protruded through surrounding fibrocartilage. This occurs most frequently in the lower lumbar region.
	Ossification of Posterior Longitudinal Ligament - A calcification of the posterior longitudinal ligament of the spinal column, usually at the level of the cervical spine. It is often associated with anterior ankylosing hyperostosis.
	Spinal Curvatures - Deviations of the spine from its normal direction or position. (Dorland, 28th ed)
	Spinal Osteophytosis - Outgrowth of immature bony processes from the vertebrae, reflecting the presence of degenerative disease and calcification. It includes cervical and lumbar spondylosis.
	Spinal Stenosis - Narrowing of the spinal canal.
	Spondylarthritis - Arthritis of the spine, specifically involving the intervertebral articulations.
	Spondylolisthesis - Forward displacement of one vertebra over another.
