Degenerative Disc disease is a term to describe the progressive, gradual wear and tear of the intervertebral disc. This degeneration affects the outer annulus fibrosis and nucleus pulposus. As the disc wearsthere is loss of disc height and increased likelihood of the development of bulging and herniated discs. Degeneration of the disc is normal with aging but can be accelerated as a result of trauma, repetitive strain or injury as well as musculo-skeletal imbalances like scoliosis. Disc degeneration itself may not be a problem, but the associated conditions that may develop as it progresses can be symptomatic and debilitating.
