Radiofrequency ablation (RFA), also known as rhizotomy, is one of the frequently used modalities in interventional pain management. This nonsurgical procedure delivers radiofrequency waves to the targeted nerves to interrupt transmission of nociceptive signals from the peripheral tissues to the central nervous system, thereby reducing pain perception. Recent studies have demonstrated the efficacy of RFA treatment as an effective interventional pain management technique to treat a variety of acute and chronic pain conditions including facial pain, headaches, postmastectomy, musculoskeletal, and major joint pain (knee, hip, shoulder, sacroiliac), and cancer pain. As more certified registered nurse anesthetists are involved in pain management, it is important to be familiar with current nonsurgical pain interventions. This journal course describes the unique mechanism of action of radiofrequency for pain modulation and provides emerging evidence to support its applications in both acute and chronic pain management.
