This is a purely diagnostic test to identify which patients will receive benefits from a radiofrequency ablation (RFA) procedure. An anesthetic is injected into the medial branch nerves supplying a targeted facet joint. Typically, several levels of the spine are injected in one procedure, and then pain is assessed over the next 24 hours. We will evaluate your pain response to determine if you are a candidate for RFA.
This exam is covered under your Alberta Health Care Plan. It is not currently offered at our Saskatchewan clinics.
