Most clinicians agree that image-guided transforaminal epidural injections are preferred to an interlaminar or caudal approach. This technique routinely delivers medication to the anterior epidural space.

Although most clinicians utilize a supraneural technique for transforaminal injections, the Kambin triangle approach offers a reasonable alternative which may provide similar outcomes. [24] The Kambin triangle technique places the tip of the needle below the spinal nerve, as opposed to the traditional supraneural approach in which the needle is positioned above the nerve.
