Randomized Controlled Trial Comparative Study
Interlaminar versus transforaminal epidural steroids for the treatment of subacute lumbar radicular pain: a randomized, blinded, prospective outcome study.
There is uncertainty in the literature over the relative effectiveness of lumbar epidural interlaminar (IL) steroid injection versus transforaminal (TF) steroid injection for lumbar radiculopathy. Most studies to date have been retrospective, or technically focused. ⋯ Results suggest that patients may experience greater subjective relief, at least initially, from TF epidural steroid injections over IL. However, more objective, and likely subacute, therapeutic effects are similar.
