Translating Evidence to Practice: A Critical and Analytical Summary of the Evidence-Based Guidelines of Facet Joint Interventions in Management of Chronic Spinal Pain.

چکیده اصلی

BACKGROUND: Chronic axial spinal pain is a major contributor to disability and healthcare expenditures, with facet joints recognized as one of the established sources of pain. STUDY DESIGN: Summary and structured synthesis of a comprehensive, multidisciplinary, evidence-based clinical practice guideline developed by systematic review of the literature, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) appraisal, and modified Delphi consensus. OBJECTIVES: This article summarizes the recommendations of the 2026 comprehensive evidence-based guidelines for facet joint interventions in the management of chronic spinal pain, published by the American Society of Interventional Pain Physicians (ASIPP). The summary is organized around the recommendations themselves, presenting for each the underlying evidence, the assigned level of evidence, the strength of recommendation, and the practical implications for clinical practice, documentation, and coverage policy. METHODS: Literature was searched from 1966 through October 2025. Methodologic quality was assessed using multiple instruments for diagnostic and therapeutic studies. Evidence was graded on a 5-level modified ASIPP scale (Level I, strong, through Level V, consensus-based) supplemented by GRADE certainty ratings, and the strength of each recommendation was rated as strong, moderate, or weak using a scheme adapted from the National Guideline Clearinghouse Extent Adherence to Trustworthy Standards (NEATS) instrument. Institute of Medicine (IOM) standards for trustworthy guidelines were followed. Consensus required at least 80% agreement among eligible panelists without a primary conflict of interest. RESULTS: For non-interventional diagnosis, the level of evidence ranged from I to V, with strong recommendations for structured physical examination and for mandatory fluoroscopic or computed tomography (CT) guidance, and weak recommendations for advanced imaging. For interventional diagnosis, the evidence was Level I to II in the lumbar spine and Level II in the cervical and thoracic spine, with moderate to strong recommendations for controlled diagnostic medial branch blocks using an 80% pain-relief threshold. For therapeutic interventions, the evidence was Level II with moderate recommendations for cervical and lumbar radiofrequency ablation (RFA) and for therapeutic facet joint nerve blocks in all three spinal regions; Level III with weak to moderate recommendations for thoracic RFA; and Level III to V with weak recommendations for intraarticular injections. For special considerations, evidence ranged from Level II to Level V, addressing repeat interventions, lesion parameters, electrode selection and position, stimulation testing, metallic and electronic implants, antithrombotic therapy, and sedation. Cost-utility analyses demonstrated costs of $4,664 to $5,446 per quality-adjusted life year for lumbar interventions and $4,994 to $5,364 for cervical interventions. LIMITATIONS: The recommendations rest on a body of literature that remains heterogeneous, with a paucity of high-quality randomized trials in the thoracic spine, in intraarticular therapy, and in most special-consideration domains. CONCLUSION: Facet joint interventions provide clinically meaningful and cost-effective benefits to appropriately selected patients with chronic axial spinal pain when diagnosis is established by controlled diagnostic blocks and therapy is delivered under image guidance with defined technical parameters. The 2026 ASIPP recommendations offer a structured, graded framework linking patient selection, procedural technique, safety precautions, and documentation. Further research is needed in the thoracic spine, in intraarticular therapy, and on the comparative effectiveness of therapeutic nerve blocks versus RFA.
