Techniques and Pearls for Thoracic MBB/RFA

[Ferrismonk]

You're right. Trajectory matters more. I just find it harder to maneuver longer needle in delicate areas.

Practice. I use 20G curved 10mm tip RF probes for occipital RF under in-plane ultrasound. You can this.

Medial to lateral? Even Ferrismonk's post above has it lateral to medial. Same as Mister Mxyzptlk's.

​

18 years in on T-spine RF. 100's to over a thousand done.
Medial to lateral, inferior to superior. Needle tip sitting on upper outer quadrant of pedicle shadow. Active tip as flat on lamina as possible.

 

[DOctorJay]

just drop a Nimbus down on it MBB style

55/year? That’s a lot of thoracic RFs.

I'm not Bob, but you should see my RVUs.

Had a good one today. Old t12 fracture. 2 techniques in one. Lumbar-like at T11/12 mb. Pedicle shadow t10 mb.

T12 and L1 Fx. Tymlos/Evenity/Prolia?
Or hold off and do a Linkedin kypho.

Re: pedicle shadow technique, how common is it to get paraspinal twitch vs traditional approach?

Re: pedicle shadow technique, how common is it to get paraspinal twitch vs traditional approach?

Pretty common. Ideally touch mid pedicle shadow, then rotate so active tip is flat on lamina and creep it up and laterally.

Pretty common in my experience as well. I make 2 burns with venom tip going med/lat. cover mid pedicle top to bottom then lateral pedicle.

Kypho only if age < 40.

Are you starting at the pedicle level below?

 

[DOctorJay]

Recent lower thoracic RFA I did with Nimbus needles

 

[lobelsteve]

Are you starting at the pedicle level below?

Yes. Or not higher than top of vertebral body of level below target.

Nope. Perpendicular

Nimbus needle Steve. Have good success with these.

Perpendicular similar to cooled.

Place it correctly and use Nimbus and you might get even better results.

I like using diros trident with perpendicular approach for thoracic.

Where are you placing for cooled RF? Pics? Thinking about doing this for a current patient.

Here was one from last week. This technique using the cooled technology gives me very consistent and durable results

With cooled being spherical do you still need that angled trajectory? Just curious.

 

[clubdeac]

No but I feel like it still may give a somewhat larger burn (no evidence of this) and it was how I was taught originally with traditional RF. Also I feel like it may be safer since you are directing the needle AWAY from the spine while staying over bone

Exact same trajectory I use for conventional.

What length active tip are you using?

 

[clubdeac]

What length active tip are you using?

Good question. 5 or 10mm I think. It’s whatever they recommend for the thoracic region. I forget

“I’ve lost all faith in thoracic medial branch blocks” - MacVicar, former SIS president, at SIS Jamaica (great place for a conference in February, btw).
Take home points for thoracic MBB/RF- for anything higher than T11 or maybe T10, if it works, we don’t know why it works, since we don’t know what we are targeting/burning.

Lol.

I have refrained from publishing this technique, as beyond the adapted drawings I can not find a primary source showing the nerves over pedicle shadow. Closest I found was superolateral foramen under lamina. I’ll just have to keep doing it this way til it stops consistently working so well…

I’ve lost all faith that the SIS thoracic RFA anatomical maps are accurate.

I’m generally a big SIS guy, but this is the one area is which the dogma is just dogma instead of the practical methods we all use for thoracic RFA

How about a case report with images and leave it at that? I've done only a handful thoracic mbb since graduating but felt much more comfortable seeing this technique here rather than what I learned in fellowship which was walking off to who knows where.

If you're using the Avanos cooled system, they come with 2/4/5.5 mm active tips. They recommend the 5.5 for thoracic if I remember right. Medtronic's Accurian is 4 and 5.5 mm active tips.

With the cooled lesion projecting forward off the active tip for about 40-50% of the lesion geometry, I would agree with aiming away from the neuraxis if you aren't using a bone backboard to protect things.

Yes it's Avanos and 5.5mm now that I think of it!

how are you all getting paid for thoracic facet interventions/rfa?

I do believe it exists. However the LCDs clearly state it's only medically necessary in Cervical and lumbar spines.......

I quit offering them 3 yrs after denials that began to stack up. Several egregious denials.

Easily covered by WC and Medicare everywhere.
Beyond that it depends on the commercial plan , but I’ve been able to get it paid by most (not all) insurances.

 

[nvrsumr]

Anyone have any lateral images they care to post. I do the pedicle shadow technique above T11 as well but often have to adjust based on lateral and needle tip ends up more cephalad than I would like when I come back to AP

I will look for some, but just use the lateral to make sure you are not way too superficial off bone or deep in the joint. Square the endplate in AP, then try to leave it alone

 

[Greenbayslacker]

Had a good one today. Old t12 fracture. 2 techniques in one. Lumbar-like at T11/12 mb. Pedicle shadow t10 mb.

It is just me or is the top needle in the second picture too shallow/posterior? Genuine question, trying to learn as I've had some successful TMBBs but haven't made the jump to RF yet.

 

[Greenbayslacker]

My images are on the right. Very poor quality fluoro machine but you can see the TP better in real life.
In AP view, I hit bone near the center of the TP and walk off the superolateral corner.
Struggling with getting a good lateral view. I know I'm far from the NF but unable to judge depth on the TP, almost looks like I'm on rib.

Nice work, i wonder the difference between your approach and superolateral approach of tp. Is it possible the suprolateral approach is ablating the middle or proximal partion of mb, where your approach is really close to the fj, maybe you are burning part of joint capsule as well LOL. I used superolateral approach of tp, the resuls are minic to the results from john’s work, couple of years relief.
