Lumbar Transforaminal Epidural Dexamethasone

Abstract

Transforaminal epidural dexamethasone provides statistically significant and clinically meaningful improvement in radicular pain at 12 weeks after injection, with parallel improvements in disability, impression of change, and satisfaction measures. There was no difference in efficacy for dexamethasone 4 mg compared with 8 or 12 mg. The optimal dose of epidural dexamethasone may be lower than 4 mg, further increasing the long-term safety and tolerability of this treatment. Current data are reassuring with regard to the safety of dexamethasone for transforaminal epidural steroid injection.
