Discs are found between each of your vertebrae along the front of your spine. Discs consist of a fibrous outer layer surrounding a gelatinous center--"like a jelly donut". Discs allow motion between vertebrae, act as a shock absorber between vertebrae and distribute the stress and strain placed on them.

Degenerative disc disease (DDD) is a condition of "aging" on your discs. It is a deterioration or change in the consistency of the disc. It is most commonly found in the low back (lumbar spine) followed by the neck (cervical spine). However, DDD can occur in any area of the spine. DDD is diagnosed by careful patient history, examination combined with x-rays and other diagnostic tests as outlined by your physician.

Normal changes during the aging process, disc herniation, injury to the disc or unusual stresses.

Pain in the involved areas of the spine, pain or numbness in the arms or legs, depending on the involved area.
