This chapter discusses the use of fluoroscopy in the performance of psoas and quadratus lumborum muscle injections. These muscles are quite often involved in the genesis of back pain. Unlike other pain syndromes, such as piriformis and thoracic outlet syndromes, that have characteristics signs and symptoms, myofascial pain involving the iliopsoas and quadratus muscles are only characterized by trigger points and/or muscle spasm. One reason for injecting the muscles is to avoid several trigger point injections using large volumes of local anesthetics.
