A Randomized Trial of Epidural Glucocorticoid Injections for Spinal Stenosis

 Janna L. Friedly, M.D et al.

 N Engl J Med 2014; 371:11-21July 3, 2014

 In a double-blind, multisite trial, they randomly assigned 400 patients who had lumbar central spinal stenosis and moderate-to-severe leg pain and disability to receive epidural injections of glucocorticoids plus lidocaine or lidocaine alone. The patients received one or two injections before the primary outcome evaluation, performed 6 weeks after randomization and the first injection. 

 At 6 weeks, there were no significant between-group differences in the RMDQ score (adjusted difference in the average treatment effect between the glucocorticoid–lidocaine group and the lidocaine-alone group).

In the treatment of lumbar spinal stenosis, epidural injection of glucocorticoids plus lidocaine offered minimal or no short-term benefit as compared with epidural injection of lidocaine alone.
