Definition

Degenerative disk disease occurs when wear and tear on the spinal disks (or discs) causes pain and other symptoms. Spinal disks serve as shock absorbers, protecting the spine and helping it stay flexible as it bends and twists. Most people experience some degeneration in disks as they age, but not all degeneration will result in symptoms characteristic of degenerative disk disease.

Causes

In degenerative disk disease, the disk is usually dehydrated, and not as resilient as normal. The fibrous tissue which holds the disk material in place may suffer small tears leading to further disk degeneration. There is some evidence that genetics may play a part in the development of degenerative disk disease in some people.

Risk Factors

A risk factor is something that increases your risk of getting a disease or condition.

The following factors may increase your risk of degenerative disk disease:

  • Age: 30s or 40s
  • Family history of degenerative disk disease
  • Athletes
  • Back injury

Symptoms

Symptoms of degenerative disk disease include:

  • 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
  • Foot drop (inability to raise the foot at the ankle)

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. Other tests may include:

  • Blood and/or urine tests to rule out other causes of pain
  • MRI Scan —a test that uses magnetic waves to make pictures of structures inside the body
  • X-ray —a test that uses radiation to take a picture of structures inside the body, especially the bones
  • Discography —injecting dye into the affected spinal area of an awake patient to obtain clearer x-ray images

Treatment

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

Physical Therapy

Physical therapy for degenerative disk disease is focused on teaching you how to manage your back pain. This may involve posture training, exercise, ice packs, heating, electrical stimulation, relaxation, and other forms of physical therapy.

Injections

Steroid injections around the nerves exiting the spinal cord may be able to provide some pain relief.

Intradiscal Electrothermal Therapy

Intradiscal electrothermal therapy, or IDET, involves inserting a small catheter with a heated tip into the disk. The heat causes shrinkage of the disk and deadens the disk's nerve endings. This is not yet a generally accepted method of treatment.

Surgery

Surgery may be required in some cases of degenerative disk disease. Surgery may involve removing the degenerated disk and/or fusing two of the vertebra together.

Prevention

Take the following steps to help protect your spine:

  • Exercise regularly.
  • Maintain a healthy weight.
  • Follow your doctor's recommendations for treating osteoporosis if you have it.
