What is a Disc Protrusion?

A disc protrusion is the result of two bones of the spine (vertebrae) compressing on a weakened disc of cartilage, which then protrudes horizontally past the disc’s normal location. The condition, also known as a bulging disc, is commonly diagnosed in people as they mature. Anyone from the age of 20 upward may have this condition, although most will never experience any symptoms from it.

The discs of cartilage in the spine consist of a gel-like center (nucleus pulposus) and a tough external ring of cartilage (annulus fibrosus). Discs are normally well-hydrated, which allows them to be pliable and absorb stresses in the spine, in turn giving us maximum flexibility to bend and twist. As we age, the discs begin to dehydrate, or lose water. The lack of water decreases the strength of the disc’s outer wall. When pressure from the vertebrae above and below is exerted on the disc, the nucleus pulposus begins to push against the walls of the weakened annulus fibrosus and can create a bulge, or disc protrusion. A herniated disc will develop when the outermost wall of the disc tears or cracks, and the nucleus pulposus seeps out and into the spinal canal.

What Symptoms Will I Experience?

A disc protrusion may never cause symptoms, but if the bulge impinges, or pinches, an area of the spinal cord or one of its nerve roots, pain can develop at the site. If the impingement is located in the lumbar (lower back) region, feelings of pain, burning, numbness, muscle spasms, weakness, and tingling may radiate into the buttocks, thighs, calves, or even the feet. Should the bulge occur in the neck, or cervical region, the same symptoms could manifest in the shoulders, arms, and hands.

Treatment

Whether you are suffering from a disc protrusion, a herniated disc, or another back and neck condition, the minimally invasive procedures performed at Laser Spine Institute may help you. Our orthopedic specialists are trained in advanced endoscopic techniques that are safe and effective. Contact us today for a complimentary review of your MRI or CT scan.

Please note: Laser Spine Institute currently does not perform endoscopic procedures on the thoracic spine.
