Degenerative Disc Disease

The intervertebral discs serve as your spine’s shock absorbers.  Growing older, trauma, injury, and wear and tear can change disc strength, resiliency and structural integrity.  Degenerative disc disease (DDD) is common in adults 50 years of age or older.  Possibly, a misnomer, DDD is not actually a disease but a condition that develops in people as they normally age.  Some people who have DDD do not know they have it.  They may only become aware of the condition when examined for another health problem.

  • Lumbar Degenerative Disc Disease

 

Other causes

Disc structure and function can be adversely affected by trauma, injury, repetitive movement, improper posture, poor body mechanics, or being overweight.  These things subject your spine to abnormal stress, some of which can be controlled or avoided.

Disc changes

Each disc is composed of a sturdy tire-like annulus fibrosis that encases a gel-like interior called the nucleus pulposus.  Endplates anchor each disc in place between two vertebral bodies.  Your body changes and slows down as you age.  Old, worn out cells are not replaced as quickly as during youth.  The cells in your discs change too.  Sometimes degeneration is accelerated by injury.  A cascade effect can develop; in other words, one structural change leads to another.

  • Disc height can be reduced and cause nerve compression and pain.
  • Bone spurs, bony overgrowths called osteophytes develop.  These can cause nerve compression, such as spinal stenosis.
  • Osteoarthritis (spondylosis) affect the spine’s joints
  • Spinal instability

Symptoms

Some people have no symptoms; they are asymptomatic.  However, DDD often is progressive, which means symptoms gradually develop and may worsen.  Pain and symptoms may spread or radiate.  Cervical radiculopathy and sciatica (lumbar) are examples.

Cervical DDD Lumbar DDD
Neck pain, mild to intense Low back pain, mild to intense
Upper extremity pain, weakness Buttock, leg pain and/or weakness
Hand clumsiness Difficult and painful to walk, stand, bend forward, backwards, side-to-side
Movement increases pain Movement increases pain
Neck, Shoulders, Arms, Hands Low Back, Buttocks, Legs
Sensations: burning, tingling, numbness, pins and needles Sensations: burning, tingling, numbness, pins and needles
Rare, bladder and bowel dysfunction Rare, bladder and bowel dysfunction

Accurate diagnosis

Consult an expert about your neck or back pain, pre-existing or changing spinal disorder.  An accurate diagnosis is essential to an effective and successful treatment plan.

Your medical history and physical and neurological examinations are very important.  You and your doctor discuss your symptoms and treatments tried.  The doctor tests your reflexes and evaluates you for muscle weakness, loss of feeling, and signs of neurological injury.

Diagnostic testing helps the doctor confirm your diagnosis.  A simple spinal x-ray will show collapsed disc space.  X-rays taken while you are bending forward, backward, or to the left and right reveal if your spine is unstable.  CT and MRI are sensitive imaging tools that reveal disc and endplate changes.  Lumbar discography uses a special fluid dye injected into one or more discs under real time x-ray (fluoroscopy) to verify damage (e.g., crack) and pain origin.


Treatment options

Non-surgical treatment often helps to relieve pain and symptoms.  Your doctor may combine two or more therapies to maximize the success of your treatment.

Non-surgical treatments

When your surgeon may discuss surgical treatment

  • Spinal instability
  • Neurologic dysfunction
  • Pain and symptoms are unrelenting
  • Non-operative treatment fails and pain persists

Surgical treatment

You may be a candidate for a minimally invasive spine surgery.  Sometimes spinal stabilization and fusion are necessary to stop the spine from moving or help alleviate progression of symptoms.
