A method of pain relief based on radio waves for patients with arthritis has been developed


In modern medicine, pain relief isone of the main elements of the treatment of many diseases. However, not all patients with varying degrees of pain can receive sufficiently effective anesthetics. One of the promising directions in the field of anesthesiology was the development of a group of medical scientists from Emory University, Georgia (USA) based on the use of an outpatient procedure that provides long-term pain relief for patients suffering from arthritis in the hip and shoulder joints.

Modern traditional methods of anesthesiologyare based on the injection of anesthetic and corticosteroids into the affected joints. The effectiveness of corticosteroids decreases over time, and becomes less effective as arthritis progresses and worsens. The use of drugs based on opioids, which are, in fact, drugs, causes unwanted addiction.

The development of American scientists is based onusing instead of injections of traditional drugs, the energetic effect on the nervous system, called, during the presentation of the invention, the technique of interventional radiology or cold radiofrequency ablation. The new methodology in anesthesiology was presented by the team leader, MD Felix Gonzalez.

The new technique consists of placing needles inthe locations of the main sensory nerve endings in the shoulder and hip joints. Then the nerves are processed with a weak radio frequency current, which "stuns" them, slowing down the transmission of pain signals to the brain.

Testing of the proposed method of anesthesia wasperformed on 23 patients with osteoarthritis who stopped responding to anti-inflammatory analgesia and intra-articular injections of lidocaine and steroids.

As a result of experimental treatment, painsensation in the shoulder decreased by 85%, and functionality increased by about 74%. Patients with hip pain experienced a 70% reduction in pain and an improvement in functionality of approximately 66%.

According to the researchers, the cold radiofrequency ablation procedure is not addictive and may in the future, in addition to treating patients with arthritis, be used in oncology and other fields of medicine.
