Randomized Controlled Trial Comparative Study Clinical Trial
Symptoms of spinal stenosis do not improve after epidural steroid injection.
This study was carried out to evaluate the therapeutic effect of epidural steroid injection on pseudoclaudication in patients with lumbar degenerative spinal canal stenosis. ⋯ The results suggest that epidural steroid injection has no beneficial effect on the pseudoclaudication associated with spinal canal stenosis as compared with epidural block with a local anesthetic alone.
