Release of the piriformis tendon and sciatic neurolysis can lead to promising results. Benson and Schutzer performed such a procedure in 14 patients (15 cases) with an average symptom duration of 38 months (minimum, 2 y). [2] All patients had piriformis syndrome secondary to trauma. Benson and Schutzer reported that 11 patients had excellent outcomes, and 4 had good results. [2] Similarly, Frieberg reported favorable results in 10 of 12 patients in whom conservative treatment failed.

Most intraoperative findings include adhesions around the piriformis muscle and anatomic variations of the divisions of the sciatic nerve above, below, and through the belly of the piriformis muscle.
