Degenerative Disc Disease

Definition

Discs lie between the spinal bones (vertebrae). They serve as shock absorbers. Discs protect the spine and help it stay flexible. Degenerative disc disease is wear and tear on these discs. This wear and tear causes pain and other symptoms. Some degeneration is normal as you age. Not all degeneration will result in symptoms of this disease.

Causes

The disc loses fluid and is not as resilient as normal. The fibrous tissue, which holds the disc material in place, may suffer small tears. These tears lead to further damage. There is some evidence that genetics may play a part for some people.

Risk Factors

Factors that may increase your chance of degenerative disc disease include:

Symptoms

Degenerative disc may cause:

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Images may be taken of the disc and surrounding area. This can be done with:
Your bodily fluids may be tested. This can be done with:
Your nerves may be evaluated. This can be done with an electromyogram and nerve conduction studies.

Treatment

Talk with your doctor about the best plan for you. Treatment options include:

Physical Therapy

Therapy for this condition is focused on teaching you how to manage your back pain. This may involve:
  • Posture training
  • Exercise
  • Ice packs
  • Heating
  • Electrical stimulation
  • Relaxation
  • Other forms of physical therapy

Injections

Steroid injections may be used for some short-term pain relief. They are injected around the nerves exiting the spinal cord.

Surgery

Surgery may be required for some. Surgery may involve removing the degenerated disc and fusing two of the vertebrae together.
