Radiofrequency thermocoagulation in pain treatment

Abstract

During the last decade there have been considerable advances in the understanding and treatment of pain. In particular we have learnt that pain must be treated swiftly and effectively to prevent the development of chronic pain. The physiological mechanisms created by the original injury or disease progress centrally, irrespective of what happens at the periphery. This central state is often not ameliorated by nerve block or severance of the afferent nervous pathways. Recent developments in pain therapy have consisted of new drugs, electrostimulation, psychotherapy and Pain Management Programmes. Radiofrequency procedures are being increasingly recognized as an accurate and controlled form of nerve block. Its advantages and disadvantages, in comparison with other pain treatments available are discussed. Indications for use and brief descriptions of the conditions, which can be treated in this way, are also included in this treatise. The complexities of technique are not as great, as might appear on first acquaintance, and the expertise required can be acquired by anyone familiar with the practice of regional analgesia. Patience, diligence and study are necessary for success, just as in any other branch of medicine. Finally there are exciting prospects for future developments, which could make radiofrequency procedures available for a wider range of pain problems than that at present.
