Abstract:
Chronic pain remains a significant global health burden, with far-reaching consequences for individual well-being, societal productivity, and healthcare resources. Despite advances in pharmacological and interventional strategies, many patients experience inadequate relief or intolerable side effects, underscoring the need for alternative approaches. Radiofrequency ablation (RFA) has emerged as a minimally invasive, targeted therapy for a wide range of chronic pain syndromes, including spine-related disorders, peripheral neuropathic pain, complex regional pain syndrome (CRPS), and refractory cancer pain. This narrative review explores the historical evolution of RFA, tracing its origins from early neurosurgical experiments to its current place in contemporary pain medicine. Mechanistic insights into RFA highlight its ability to disrupt nociceptive pathways at both cellular and molecular levels, with biophysical principles guiding lesion formation and efficacy. The review examines conventional, pulsed, cooled, and bipolar RFA techniques, comparing their effectiveness and indications across pain syndromes. Recent technological innovations, such as advanced image guidance, neuro-navigation, robotic assistance, and regenerative hybrid strategies, are discussed as transformative trends poised to enhance the precision and outcomes of RFA. The safety profile, including immediate and delayed complications, is critically appraised alongside established preventive strategies and management protocols. Evidence from clinical trials, meta-analyses, and professional guidelines is synthesized to inform best practice, while also addressing ethical, legal, and accessibility considerations in diverse patient populations. Collectively, this review underscores the evolving role of RFA in chronic pain management, highlights persistent challenges, and calls for ongoing research to optimize patient selection, procedural safety, and equitable access worldwide.
