Epidural Administration of Spinal Nerves With the Tumor Necrosis Factor-Alpha Inhibitor, Etanercept, Compared With Dexamethasone for Treatment of Sciatica in Patients With Lumbar Spinal Stenosis

Abstract

Our results indicate that epidural administration of a TNF-α inhibitor onto the spinal nerve produced pain relief, but no adverse event. TNF-α inhibitors may be useful tools for the treatment of radicular pain caused by spinal stenosis.
