Discs, which act as shock absorbers for the spine, are located in between each of the vertebrae in the spine. Each disc contains a tire-like outer band (called the annulus fibrosus) that surrounds a gel-like substance (called the nucleus pulposus). A herniation occurs when the outer band of the disc breaks or cracks and the gel-like substance from the inside of the disc leaks out, placing pressure on the spinal canal or nerve roots.

In addition, the nucleus releases a chemical that can cause irritation to the surrounding nerves causing inflammation and pain. The following picture shows what happens different types of disc injuries. Disc injuries if left untreated can compress nerve roots and even the spinal cord, leaving the patient with various types of symptoms.

How Do Discs Herniate?
Most cervical disc herniations occur as a result of sudden stress. This occurs during movements resulting in sudden flexion, extension, or twisting of the neck, such as during a fall or auto accident. Sometimes they occur gradually, over weeks or months. There are risk factors that can contribute to the chances of a disc herniation, including:

• Aging- As we get older, discs gradually dry out, affecting their strength and resiliency.
• History-Major or minor trauma to the cervical spine.
• Lifestyle choices- Lack of regular exercise, not eating a well-balanced diet, and tobacco use substantially contribute to poor disc health.
• Poor posture- incorrect and/or repetitive lifting or twisting can place additional stress on the cervical spine.

Chiropractic has been a natural solution helping millions with a variety of disc problems.
