    AbstractPiriformis syndrome is an uncommon cause of buttock and leg pain. Some treatment options include the injection of piriformis muscle with local anesthetic and steroids. Various techniques for piriformis muscle injection have been described. Ultrasound allows direct visualization and real time injection of the piriformis muscle. We describe 5 consecutive patients, diagnosed of piriformis syndrome with no improvement after pharmacological treatment. Piriformis muscle injection with local anesthetics and steroids was performed using an ultrasound technique based on a standard technique. All 5 patients have improved their pain measured by numeric verbal scale. One patient had a sciatic after injection that improved in 10 days spontaneously. We describe an ultrasound-guided piriformis muscle injection that has the advantages of being effective, simple, and safe.Copyright © 2016 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.
