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 ...
Neurotomy may refer to the application of heat (as in radiofrequency nerve lesioning), chemical ablation, or freezing of sensory nerves with the intent of a longer term (months or years) ablation or partial denervation of one or more peripheral nerves, usually to relieve chronic pain.
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).
The primary symptom is pain and it may be localized to the distribution of one or more of the intercostal nerves, manifesting as chest and abdominal pain. [18] No treatment modality prior to neurectomy (e.g. systemic medications, cryoablation, therapeutic nerve blocks, and radioablation) has given effective pain relief and none have been curative.
Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

In chemical neurolysis, a needle injects alcohol or phenol into the nerve and prevents the conduction of pain signals. Neurolysis can also be accomplished through a process known as radio-frequency lesioning. [2] In radio-frequency lesioning, a needle transmits radio waves to the nerve and interrupts regular pain signaling. [5]
However, the pain or other symptoms often radiate to the part of the body served by that nerve. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm. Likewise, an impingement in the lower back or lumbar-sacral spine can be manifested with symptoms in the foot.
Spinal decompression is the procedure which reduces pressure on the spinal cord. Spinal decompression is the relief of pressure on the spinal cord or on one or more compressed nerve roots passing through or exiting the spinal column. [1]
