title: Transforaminal lumbar epidural steroid injections.
abstract: Low back pain is an important medical, social, and economic problem involving approximately 15% to 39% of the population. Of the numerous therapeutic interventions available for treatment of chronic low back pain, including surgery, epidural administration of corticosteroids is one such intervention commonly used. Several approaches available to access the lumbar epidural space are the caudal, interlaminar, and transforaminal, also known as nerve root or selective epidural injection. The objective of an epidural steroid injection is to deliver corticosteroid close to the site of pathology, presumably onto an inflamed nerve root. This objective can be achieved by the transforaminal route rather than the caudal or interlaminar routes. Reports of the effectiveness of epidural corticosteroids have varied from 18% to 90%. However, reports of the effectiveness of transforaminal epidural steroids have shown it to be superior, with outcome data indicating cost effectiveness as well as safety. This review describes various aspects of transforaminal epidural steroid injections in managing chronic low back pain.
