![]() Comprehensive Evidence-Based Guidelines for Facet Joint Interventions in the Management of Chronic Spinal Pain: American Society of Interventional Pain Physicians (ASIPP) Guidelines. Less commonly, medial branch block injections are used therapeutically after a positive diagnosis and involve injecting a combination of an anesthetic and a corticosteroid for sustained pain relief (2-4 months).ĥ Manchikanti L. See Radiofrequency Ablation (RFA) Side Effects and Risks Effectiveness of Lumbar Facet Joint Blocks and Predictive Value before Radiofrequency Denervation: The Facet Treatment Study (FACTS), a Randomized, Controlled Clinical Trial. RFA treatments are preferred as they offer longer pain relief (6 to 12 months) and are not associated with the potential risks linked to repeated corticosteroid use.Ĥ Cohen SP, Doshi TL, Constantinescu OC, et al. Treatment planning: A positive response to medial branch block injections also indicates that a patient will likely benefit from medial branch radiofrequency ablation (RFA) treatments that involve creating heat lesions on the nerves to prevent long-term pain signaling.Diagnostic: Significant pain relief following the anesthetic injection suggests that the facet joints are involved, while lack of pain improvement indicates they are likely not the main contributor to pain.Diagnostic and therapeutic spinal interventions: Facet joint interventions. Neurol Clin Pract. The primary purpose of medial branch blocks is to diagnose or pinpoint pain originating from a facet joint(s) and guide further treatment if a positive response is seen.ġ Said N, Amrhein TJ, Joshi AB, N NCN, Kranz PG. The injection aims to block the pain signals transmitted through the medial branch nerves and produce targeted pain relief. Treasure Island (FL): StatPearls Publishing 2023 Jan. Available from: A medial branch nerve block is a minimally invasive injection procedure that involves injecting a small amount of a local anesthetic, with or without a corticosteroid, near the medial branch nerves – the small nerves near the facet joints of the spine that carry pain signals from the joints to the brain.ġ Said N, Amrhein TJ, Joshi AB, N NCN, Kranz PG.
