What is Degenerative Disc Disease?
The intervertebral discs, soft structures which sit between the spinal bones (vertebrae), may deteriorate with age or injury. A normal intervertebral disc during early adulthood has a large amount of water within it, which gives it many of its important properties. With age, the water content of the disc reduces, and the disc loses some of its height. The disc may bulge, and additional bone may form at the edges of the vertebrae and discs (osteophytes). As a result of this process, the spinal canal and forminae (tunnels for the spinal nerves) can narrow, resulting in pressure on the nerves and/or spinal cord.
