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).
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
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 ...
Magnetic resonance image of lumbar spine Nerve block of the cervical spine. Lumbar sympathetic neurolysis is typically used on patients with ischemic rest pain, generally associated with nonreconstructable arterial occlusive disease. Although the disease is the basis for this type of neurolysis, other diseases such as peripheral neuralgia or ...
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]
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
Cervical facet joint block – minor injections at the joints of the affected regions of the cervical spine; Media branch block and radio-frequency ablation – diagnosis and alleviation of pain from specific medial branches of the spinal nerve upon administering anaesthetics in the cervical region of interest to locate the area for treatment ...
An L1 laminectomy is then performed: a section of the spine's bone, the spinous processes together with a portion of the lamina, are removed, like a drain-cap, to expose the spinal cord and spinal nerves underneath. Ultrasound and an X-ray locate the tip of the spinal cord, where there is a natural separation between sensory and motor nerves.
