Transforaminal epidural steroid injection in lumbar spinal stenosis: an observational study with two-year follow-up.

Abstract

Transforaminal epidural steroid injection (TFESI) is recognised as a treatment for symptomatic lumbar disc herniation, whilst surgical decompression is generally thought to be the most effective treatment option for lumbar spinal stenosis. There is little available literature examining the effect of TFESI on symptomatic lumbar spinal stenosis.
