Piriformis Syndrome: Comparison of the Effectiveness of Local Anesthetic and Corticosteroid Injections: A Double-Blinded, Randomized Controlled Study

Abstract

Background: Piriformis syndrome (PS), which is characterized by pain radiating to the gluteal region and posterior leg, is accepted as one of the causes of sciatalgia. Although the importance of local piriformis muscle injections whenever PS is clinically suspected has been shown in many studies, there are not enough studies considering the clinical efficacy of these injections.
