Left paracentral disc extrusion — overview and treatment

A left paracentral disc extrusion is a herniated disc that is pushing inner disc material into the left-central portion of the spinal column. Most herniated discs never exhibit symptoms and often heal themselves. However, if displaced disc material compresses a nerve root or the spinal cord, it may cause symptoms such as pain, tingling, numbness or muscle weakness.

Because irritation from a left paracentral disc extrusion occurs on the left side of the spinal cord — typically affecting a nerve root branching off to the left — symptoms are experienced on the left side of the body. These symptoms may cause permanent damage if left untreated.

Causes of left paracentral disc extrusion

Discs act as cushions to separate the vertebrae of the spine. These discs are comprised of a gel-like inner material and a fibrous outer wall. As the body ages, discs begin to lose their elasticity and height. Increased pressure from the central core forces weakened portions of the disc’s exterior outside of the disc’s normal boundaries — also known as a bulging disc.

If a disc develops a crack or tear, the gel-like material may be pushed through the tear and into the spinal canal, affecting the spinal cord and nearby nerve roots. This condition can also be caused by a traumatic disc injury.

Treatment for left paracentral disc extrusion

Conservative treatment options for a paracentral disc extrusion include the following:

  • Pain or anti-inflammatory medication
  • Exercise
  • Lifestyle changes like posture improvement or weight loss
  • Physical therapy
  • Spinal injections

These and other options may help you manage chronic symptoms while the disc heals. Consult your doctor to receive a proper diagnosis and develop a personalized conservative treatment plan. However, if symptoms are too severe for conservative treatments to sufficiently relieve pain, surgery may become an option. If your chronic symptoms persist after several weeks or months of conservative treatment, contact Laser Spine Institute to learn about the advantages of minimally invasive spine surgery.
