Widely used epidural injections of glucocorticoid plus lidocaine offered little or no benefit over epidural injections of lidocaine alone in treating symptoms of lumbar spinal stenosis, according to findings of a randomized controlled trial of 400 people (Friedly J et al. N Engl J Med. 2014;371:11-21).
At 6 weeks, patients who had received the fluoroscopically guided glucocorticoid-plus-lidocaine injections showed no difference in pain-related functional disability or in pain intensity than patients who had received only lidocaine. At 3 weeks, pain and function outcomes were slightly better in the glucocorticoid-lidocaine group, which may account for these patients reporting greater treatment satisfaction and reduction in depressive symptoms. Participants in both groups had decreased pain and improved function.
