Degenerative disc disease

Summary of Degenerative disc disease
Degenerative disc disease is a pathologic process of degeneration of the intervertebral discs. Disc degeneration is a disease of aging, and though for most people is not a problem, in certain individuals a degenerated disc can cause severe chronic pain if left untreated. The typical radiographic findings are disc space narrowing, vacuum disc, end plate sclerosis, and osteophyte formation.
