Degenerative disc disease

Lumbar disc degeneration is the most common cause of low back pain and it is a target of diagnostic and surgical intervention. Pathology of intervertebral disc degeneration has been approached from a variety of ways, there is no consensus as to what disc degeneration actually is or how it can be distinguished from the physiological process of growth, aging, Healing and adaptive remodeling. Intervertebral disc consists of three components: an inner gelatinous nucleus pulposus, outer annulus fibrosus and cartilage end plates located superiorly and inferiorly. The intervertebral disc is one of the largest avascular tissues derive their nutrition from vessels in the subchondral bone adjacent to the hyaline cartilage of the end adjacent to the hyaline cartilage of the end plate.
