About Lumbar Degenerative Disc Disease

Despite its name, lumbar degenerative disc disease isn’t actually a disease. But that doesn’t make the pain it causes any less real. Whether it’s the result of aging or injury, lumbar degenerative disc disease can limit your activity. Some people even need surgery. If you’re one of them, Medtronic offers a treatment option.

Definition

As discs lose their water content because of disease or age, they lose their height, bringing the vertebrae closer together. As a result, the nerve openings in your spine become more narrow. When this happens, the discs don’t absorb the shocks as well, particularly when you are walking, running, or jumping.

Wear and tear, poor posture, and incorrect body movements can also weaken the disc, causing disc degeneration.

Causes

For some of us, degenerative disc disease is part of the natural process of growing older. As we age, our intervertebral discs can lose their flexibility, elasticity, and shock-absorbing characteristics. For others, degenerative disc disease can stem from an injury to the back.

Symptoms

Degenerative disc disease may cause back and/or leg pain, as well as functional problems such as tingling or numbness in your legs or buttocks, or difficulty walking.

Risk Factors

The aging process and wear and tear on your spine can damage a disc in your back. A damaged disc can also be caused by repetitive activities or an injury to the spine.

Diagnosis

The diagnosis of degenerative disc disease begins with a physical examination of the body, with special attention paid to the back and lower extremities.

Your doctor will examine your back for flexibility, range of motion, and the presence of certain signs that suggest that your nerve roots are being affected by degenerative changes in your back. This often involves testing the strength of your muscles and your reflexes to make sure that they are still working normally.

You will often be asked to fill out a diagram that asks you where your symptoms of pain, numbness, tingling, and weakness are occurring. x-rays or a magnetic resonance imaging (MRI) may be ordered.
