Posterior Central Disc Protrusion

A posterior central disc protrusion occurs when the inner gel-like material of a vertebral disc begins to strain against the outer disc wall. This causes the disc to bulge outside of its normal perimeter within the spinal column. A “posterior central” protrusion is one that pushes straight toward the back (away from the abdomen). This puts the protrusion directly in line with pressing upon the spinal cord.

A healthy intervertebral disc has a strong, fibrous wall that’s many layers thick. This resilient disc wall is designed hold the soft inner material of a disc in place, and the wall also helps the disc maintain its cylindrical shape. However, due to accidents, injuries, and age-related changes, the outer wall of a disc can deteriorate, making the discs susceptible to becoming misshapen or tearing open.

In the case of a posterior central disc protrusion, the wall of the disc has not torn open, but it has weakened to the point that it’s allowing inner disc material to bulge out. This could be an indication that the disc is close to rupturing. Even before rupturing, however, any disc protrusion or bulge can invade the surrounding spinal canal and put pressure on the spinal nerves, which is ultimately what causes painful disc protrusion symptoms.

Disc protrusion treatment can take many forms, but when patients find that mild pain relief options, like medication, chiropractic work, and rest, are not effective, they may decide to undergo surgery. If you are considering surgery to treat your posterior central disc protrusion, we suggest that you contact Laser Spine Institute (LSI). Our medical team can tell you more about our minimally invasive, endoscopic procedures for back and neck conditions. These procedures require no large incisions, no general anesthesia, and no lengthy hospital stays. Contact us today for more information and to receive a free review of your MRI or CT scan.

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