Radiofrequency waves are used to produce heat on specifically identified nerves surrounding the facet joints called the lumbar medial branches of the dorsal ramus of the spinal nerves. [33] By generating heat around the nerve, the nerve is ablated, thus destroying its ability to transmit signals to the brain.
Neuroablation can be performed with chemical neurolysis or radiofrequency ablation. These techniques are often used on the medial branch nerves to treat low back pain and have been applied to the superior cluneal nerves. The use of phenol has been noted to relieve pain for up to 9 months but may not completely resolve symptoms. [5]
Radiofrequency ablation or lesioning, also known as rhizolysis, can be used to give longer lasting relief by destroying the nerves that supply the facet joint (medial branch nerves). [9] Current guidelines as per the International Spine Intervention Society require two successful medial branch blocks before progressing to a radiofrequency ablation.
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 ...
The first three lumbar nerves, and the greater part of the fourth together form the lumbar plexus. The smaller part of the fourth joins with the fifth to form the lumbosacral trunk, which assists in the formation of the sacral plexus. The fourth nerve is named the furcal nerve, from the fact that it is subdivided between the two plexuses.
