Interventional Radiology

Rhizotomy -

CT or X ray guidance is used to position an electrode so that a small amount thermal energy can be delivered to disrupt pain circuits, the circuits / nerve  pathways go to areas of chronic pain like for example the pain of osteoarthritis.  The most common site involves the lumbar facet joints although other sites such

as the knee joint are also sometimes targeted.  The pain relief typically lasts

from 8 to 9 months.
