Current Knowledge of Epiduroscopy

Abstract

Epiduroscopy is a new, minimally invasive diagnostic and therapeutic modality for intractable low back pain. Numerous studies have demonstrated its utility in reducing low back and leg pain in patients with lumbar disk herniation, degenerative lumbar spinal stenosis, and failed back surgery syndrome. Recently, several authors described potential uses and new techniques for epiduroscopy. In this article, we review the physiologic rationale and the available clinical evidence discussed at the Japan Society of Epiduroscopy.
