I took the ASIPP course, and had someone proctor me. I've started doing these over the last 3 years. I've probably done 50-100 of these cases. Performed overwhelmingly on nonPI patients after diminishing benefit from RFA. To my understanding most insurances cover this procedure. We had the tower and the endoscopic trays, you'd have to call the reps joimax, or elliquience, but whatever a strkyer tower cost 50k? A tray to only get the above mentioned items maybe 30K. Upfront cost are high. Patients do extremely well. I've posted the below study note years of relief. Effectively you are avulsing the nerve and its tributaries in a wide area with direct visualization under the scope with higher temperatures with the bipolar. Jason Kapra does these in 15 minutes I believe under single incision. Some use the burring tool, I do not routinely. I get these referrals from some of the spine surgeons in the area.

Percutaneous radiofrequency ablation of spinal nerves is effective; however, the long-term efficacy is unsatisfactory due to the variation of dorsal medial branch and the recurrence caused by nerve regeneration [
10].
Indications for EFRA include (1) chronic lumbar zygapophysial joint pain with a definite diagnosis of controlled MBB and patient has a pronounced surgical aspiration and (2) failure or short-time recurrence after 6-week standard conservative treatment and percutaneous radiofrequency ablation. In the current study, the therapeutic effect of ERFA is superior to percutaneous radiofrequency ablation. The reasons may include direct vision of the variability of the nerve under endoscopy [
11], with direct vision under endoscopy, ablation can be more accurate and reduce nerve root injury rate, reducing the incidence of sensory loss or analgesia of skin; nerve regeneration is fairly rare after a long segment ablation and additional radiofrequency denervation on the severed nerve end, the long-term efficacy is better [
12]. The sensation and motor tests with radiofrequency needle contribute to determine the accurate position that endoscopic channel placement was immediate and prompt.
In summary, radiofrequency needle guiding ERFA has advantages of more accurate positioning, more thorough denervation, fewer complications, lower risk, and better long-term efficacy up to 5 years post-procedure. The surgery may be used in selected patients. However, this study involves a small sample size and short follow-up time. The long-term efficacy needs further follow-up studies.

Chronic lumbar zygapophysial joint pain is a common cause of chronic low back pain. Percutaneous radiofrequency ablation (RFA) is one of the effective management options; however, the results from the traditional RFA need to be improved in certain ...
