Piriformis Injection eMedicine Procedures

Description: Piriformis syndrome is a common cause of buttock and posterior leg pain. Typically, the piriformis muscle becomes taut, tender, and contracted. This causes a deep aching sensation in the mid-gluteal region that is sometimes associated with pain radiating down the posterior leg. The tight piriformis muscle may cause a nerve and vessel entrapment syndrome because of its close proximity to the sciatic nerve and surrounding vessels.
