Figure 3: (a) Schematic representation of “Kambin's triangle.” The hypotenuse is the exiting nerve; the base is the caudal vertebral body, and the height is the traversing nerve root. (b) Schematic description for TFESI with Kambin's triangle versus the subpedicular approach (target L5 nerve root). Ann Rehabil Med 2011;35:833-43. DOI: 10.5535/arm. 2011.35.6.833. TFESI: Transforaminal epidural steroid injection
