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 a normal disc. 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:

• Increased age
• Family history of degenerative disc disease
• Sports
• Back injury
• Smoking
• Heavy physical work
• Obesity

Symptoms    ▲

Degenerative disc may cause:

• Pain in the low back, buttocks, thighs, or neck
• Pain that worsens when sitting, bending, lifting, or twisting
• Pain that feels better when walking, changing positions, or lying down
• Periods of severe pain that gets better after a few days or months
• Numbness and tingling into the legs
• Weakness in the legs
• Inability to raise the foot at the ankle

Diagnosis    ▲

You will be asked 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:

• MRI scan
• X-ray
• Discography

Your bodily fluids may be tested. This can be done with:

• Blood tests
• Urine tests

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:

Prevention    ▲

To help reduce your chance of degenerative disc disease:

• Begin a safe exercise program with the advice of your doctor.
• Maintain a healthy weight.
• If you have osteoporosis, follow your doctor's instructions for treating the condition.
• If you smoke, talk to your doctor about ways to quit.
• If possible, make changes to your workplace to reduce symptoms, such as using proper posture and safe methods of lifting.
