Combined fluoroscopic and nerve stimulator technique for injection of the piriformis muscle.
The diagnosis of radicular pain secondary to Piriformis Muscle Syndrome has been historically difficult due to lack of accurate means to identify and selectively inject the piriformis muscle. This paper describes a simple and reproducible technique to safely inject the piriformis muscle, using a combination of fluoroscopic guidance and a standard neuro-muscular stimulator.
