What Are The Warning Signs And Causes Of Piriformis Syndrome?

Trauma To The Buttocks

Piriformis syndrome can occur due to an individual experiencing trauma to the buttocks. Trauma or injury to any tissue causes an inflammatory response by the body. The inflammatory response is a cascade of events that occurs to repair and heal damaged tissues. When cells of connective tissue become extensively damaged, the tissues that form during the cellular repair process are different than the tissues present before the injury. This new tissue is often referred to as scar tissue and is made out of new collagen fibers. Scar tissue is different than the original connective tissues in the way it arranges itself in an unmethodical, mismatched configuration instead of the interlocked and aligned fiber arrangement of the original tissue. Sometimes scar tissue from an injury forms adhesions, or bands of scar tissue that inappropriately connect to other, healthy neighboring tissues. When an individual is affected by an injury or trauma to the buttocks, the cellular damage is repaired with this scar tissue. Adhesions can form between an individual's sciatic nerve, piriformis muscle, and the top of the greater sciatic notch. This malfunction can compress the sciatic nerve and result in piriformis syndrome.
