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 ...
The procedure may destroy pain nerves without damaging nearby tissues, though evidence for this comes only from studies with cadavers. [1] Testing on pigs suggested it heats the desired area without damaging the dorsal root ganglia or spinal nerve roots , though the cells of the disc demonstrate histological changes.
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. [19] The success outcome is typically measured as a 50% or more decrease in visual analog scale (VAS) scores, which are numerical pain scores from 0 - 10 or ...
Neurolysis is commonly performed only after a successful celiac plexus block. [4] CPN and celiac plexus block (CPB) are different in that CPN is permanent ablation whereas CPB is temporal pain inhibition. [4] There are multiple posterior percutaneous approaches, but no clinical evidence suggests that any one technique is more efficient than the ...

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).
Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel ...
