As the title says, I'm a new private practice doc who recently finished fellowship where we exclusively used boston scientific palisades for our SI RFA's. They were great and made the procedure a breeze. I did my first post-fellowship SI RFA today without the palisade (too expensive) and it was a struggle. Any advice from the wiser docs out there? Can I make my own alternative and autoclave it? I prefer to use bipolar for my SI RFA's.
 
Be careful with this procedure bc it rarely gets paid these days.

Just put an 18g needle next to the S1 and S2 foramen. Burn it for 120-150 seconds at 80C.

Make sure you get the L5 DPR at the sacral ala.

Lay an 18g on the skin over the target area, mark the top and bottom, and lay a ruler over those points and mark off 1 cm intervals. Numb and insert needles. Other thing to keep in mind is needle cost in private practice. At $12-15 each it adds up given the comparatively poor reimbursement. I’ve modified my technique over time to save time and money.

Start with 2 needles next to each other on the L5 , bipolar burn, then 5 needles in a line over the sacrum, bipolar burn needles 1-2, 3-4, then leapfrog them down and burn 2-3, 4-5. Bipolar for the whole thing means you don’t need a grounding pad.
 
I had a similar issue. All SI were with cooled RF in fellowship. Look up the Cosmon Palisade technique article, can Google it. Not that difficult to space out approximately 1 cm on the skin by eyeballing it

This is fantastic. Thank you. What is your typical bipolar burn? 120 sec at 80 Celsius?

You actually use this many needles?

I can't see why TBH.

5 needles, no grounding pad, doesn’t seem too bad to me. I do the L5DR, then move those 2 needles and place the other 3 for the sacrum. Could do it with 4 by moving the top needle to the end of the line for the second sacral burn, but that would be several extra fluoro shots and add some time.
 
3 needles. One at L5 DPR and one at S1 and S2.
I do the Palisade technique because I read a study a while back that showed it had one of the highest likelihoods of capturing the nerves, while monolpolar techniques were much lower. I’ve done it that way though on a few very skinny patients where I was worried the needle perpendicular to the skin could burn their skin. In those though it’s very easy to lay the needle parallel to the surface of the sacrum so you get a 1 cm long burn adjacent to the foramen.

No S3?

I do something in between you two.

4 needles.

First burn: bipolar on L5, and bipolar vertical strip lateral to S1.

Second burn: bipolar vertical strip lateral to S2, bipolar vertical strip lateral to S3.

So so results.

Deleted my reply that was basically reiterating this post. I do palisade technical as well. Say for left side - the lateral branches can come anywhere from 1 to 5 o'clock so palisade makes sense to me as most likely to catch it.

Sometimes I have trouble visualizing S3 so did not like the 2 needle technique at each foramen.
 
I’ve had good results with 18g needles, caudal tilt and traditional burn x1 at L5, S1, S2 then rotate and reposition slightly and burn again. I’ve had overall pleased patients and a few home runs with this. Technically easy and takes no longer than lumbar RFA.

I do the same. The Thouy in your standard epidural tray is a great ruler and radiopaque marker at the same time.
 
I draw on a cocktail napkin or notebook paper before every case.
1. Sacral ala and S1 single lesion 90d/90s
2. Bipolar lesion S2 and S3 (4 probes) upper half
3. Bipolar lesion S2 and S3 (4 probes) lower half

4 pokes total. S1 poke on skin used for S1 and S2. 4 probes, but clamp off separately to drapes so you can match concurrent bipolar lesioning. I use an Ioniq 4 channel.
 
Medicare and the local Medicaid plan pay for it. The two of those are probably 70% of my practice. Private insurance usually denies it.
Medicare advantage plans also don't cover, in my area. I offered one patient to do cash pay, and she said, "why don't I just go to Dr X for fusion? That will be covered, and then it'll be fixed for good!"

Dr X is a surgeon, at least, instead of a competing pain doc. Sigh
 
Rarely.

Almost never do it.
we are only doing it for medicare patients and in office. no longer at ASC where it wasnt even reimbursing $100 so not worth the time we found out.

same thing for genicular. reimbursement in office is usually at least 4x higher. it does suck not having sedation but so far patients just accept it and go for the procedure anyway.

Fyi, If you localize from the AP and from the lateral to the periosteum, the procedure is much much less painful.

To add my 2c:
We only do SIJ RF for straight medicare anymore, noone else will pay for it. I use a hybrid technique. I do L5DR in AP, then will come in low and flat with 10mm 20G RF cannulas and lie two needles down on the bone medial to the inferior 3rd of the SI joint, then one more medial to the S2 foramen. Monopolar. If they have a particularly large SI sacrum, I may walk the two inferior needles cephalad along the joint if needed for one additional burn. I haven't noticed any difference with this technique compared to bipolar or pallisade type lesions.

And how often do they come back to you because that fusion "didn't work"?
 
All these medicare disadvatange plans are pain in the arse. Really its private insurance with medicare rate
