Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Knee pain relief of 50% or more following genicular RFA may last from several months to two years, [129] [132] and can be repeated by the same outpatient procedure when pain recurs. [129] Injection of phenol may be used as a neurolytic treatment of sensory knee nerves to relieve chronic pain from knee osteoarthritis. [134] [135]
Knee osteoarthritis is a major cause of pain and disability worldwide, with prevalence estimated at about 4% of the population, particularly among the elderly. [40] Radiofrequency ablation of certain knee nerves is an outpatient procedure to reduce chronic arthritic pain.
Radio frequencies at non-ablation energy levels are commonly used as a part of aesthetic treatments that can tighten skin, reduce fat by lipolysis and also apoptosis, [4] or promote healing. [5] RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures. It is commonly used for muscle ...
Radiofrequency thermocoagulation is a thermal pain treatment procedure. For example, percutaneous intradiscal radiofrequency thermocoagulation (PIRFT) involves the placement of an electrode or catheter into the intervertebral disc and applying an alternating radiofrequency current. [1] [2] [3]
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Therefore, they can be used for several kinds of surgeries which hitherto had been carried out by open or endoscopic surgery, such as for trigeminal neuralgia. Long-term follow-up data has shown it to be as effective as radiofrequency ablation, but inferior to surgery in preventing the recurrence of pain. [citation needed]
Targeted radiofrequency ablation (also written t-RFA) is a minimally invasive procedure to treat severe pain and discomfort caused from metastatic tumors in the vertebral body of the spine. This procedure uses radiofrequency energy to target and ablate a specific spinal tumor, causing it shrink and reduce the pressure on the surrounding nerves ...
