Epidural Steroid Not Better Than Placebo Injection for Sciatica and Spinal Stenosis Pain and Function
Am Fam Physician. 2016 Feb 15;93(4):315a-316.
Is epidural corticosteroid injection effective for reducing pain and improving function in patents with radicular low back pain or spinal stenosis?
It is hard to figure out what to do with these results. On the one hand, steroid injection did not provide a significant benefit compared with placebo injection in patients with radicular pain or spinal stenosis. However, part of the reason for this may be the significant and sustained improvement of pain scores seen with the placebo injection. This improvement might reflect natural history, but it may reflect the ability of patients treated with either injection to reframe the pain, because short-term improvement in function was (unlike pain relief) quickly
