The objective of the LESS Randomized Trial is to improve the quality of life for patients suffering from lumbar spinal stenosis. This project aims to examine the safety and clinical efficacy of epidural steroid injections for treatment of pain associated with lumbar spinal stenosis.

Rate of Epidural Steroid Injections Epidural steroid injections have rapidly become standard of care for treating spinal stenosis - even in the absence of compelling evidence of safety and efficacy. The LESS (Lumbar Epidural Steroid Injections for Spinal Stenosis) Trial aims to determine whether or not lumbar epidural steroid injections improve functional status and pain associated with spinal stenosis. The main objective of the study is to conduct a blinded, randomized controlled trial (RCT) in patients 65 years and older with spinal stenosis to test if the safety and effectiveness of epidural steroid injections (ESI) plus local anesthetic (LA) is greater than LA alone.
