Effect of pre-injection opioid use on post-injection patient-reported outcomes following epidural steroid injections for radicular pain

Increased pre-injection opioid use does not impact long-term outcomes after ESIs for degenerative spine diseases. A pre-injection MEA around 50 mg/day may represent a threshold above which the 3-month effectiveness of ESI for back- and neck-related disability decreases. Epidural steroid injection is an effective treatment modality for pain in patients using opioids, and can be part of a multimodal strategy for opioid independence.
