Is the lumbar facet rhizotomy a risky thing to do?

FACET RHIZOTOMY. A lumbar facet rhizotomy is a minimally invasive procedure that can, when successful, relieve back or neck pain caused by facet joints. Risky? All surgical procedures are risky, especially when done along the spinal nerves. Ask your doctor about the risks you are worried about. Best luck.
No done by trained. Not if done by a physician who specializes in spinal interventions. It is not risk free but the risks are small when done in the proper setting by the right individual.
