Neurotomy

[Eastex]

I am not sure, but my paper work says "CERVIVAL, THORACIC, AND LUMBOSACRAL NEUROTOMY INFORMATION" What is a Neurotomy and why is it helpful?
"This procedure is done to treat pain caused by facet joints by creating a lesion or burn in the pain fibers to the facet joints also known as the Medial Branch of the posterior primary ramus. The purpose of RFTC of the medial branch is to decrease pain and inprove function. This is done only if pain is relieved temporarily by facet joint injections and the by medial branch nerve blocks" I have had facet joint injections and medial branch nerve blocks already
