In lumbar spinal stenosis, what is the evidence for steroid injections?

• A. They are the first-line treatment
• B. They do not have enough data to back up benefit
• C. They are contraindicated
• D. They are clearly beneficial

Answer: (B)

In lumbar spinal stenosis, epidural steroid injections are studied to see if reducing inflammation around the compressed nerve roots translates into meaningful, lasting improvement. The best evidence shows they can provide short-term relief of radicular leg pain, but there isn’t consistent, durable data showing long-term improvement in function or walking distance. Meta-analyses and guidelines generally conclude that, while injections may help temporarily or as a bridge to other treatments, they do not reliably demonstrate a clear, lasting benefit. They’re not the first-line therapy, not contraindicated, and may be used selectively for short-term relief, but overall the data aren’t robust enough to prove a meaningful benefit.
