Does anyone have tips on how to move more efficiently for this procedure?
A few of my thoughts
- use 7 minute burn
- start at S1 (always the most challenging for me) then go to other levels
- put two trochars in at once + use straight AP view.
What am I missing?
- use 7 minute burn
Definitely, as long as targeting is dead on.
- start at S1 (always the most challenging for me) then go to other levels
Agreed. Plus start on left so moving c arm to lateral is easier. If doing L4 L5 and S1, after the S1 left, do L4 right, as often entry point for S1 left is same as entry point for L5 left.
Also consider, Only going oblique just enough to see borders of S1 pedicle, entering skin just medial to iliac crest and accessing out of plane. Pull tip hard medial and consider using bevel tip. My last few cases have actually ended up to posterior at S1, would’ve been ideal at L3 through L5, even straight stylet wasn’t getting ventral enough. had to advance Trocar further into vertebral body then re start J stylet. Still ended up a bit off, at border 60% anteriorly. 15 minute burn time needed… also, don’t forget retraction method if need to get it more posterior.
- have 2 c-arms
Yes, but can be somewhat cumbersome around the table. That said, a lot of time is spent maneuvering to lateral, getting around a right sided trochar, re-obtaining proper wigwag, etc. I may revisit this myself next case.
- put two trochars in at once + use straight AP view.
- unless docked in bone, trocar tends to flop without holding it with a clamp.
Also Don’t know how much this would help, as could only burn one at a time. If/when I get the next access point ready to burn before the first lesion is done, I do move on to the next level access if there is one. Granted, I then have to reposition the C-arm back to second lesion location confirming in AP and lateral electrode is in correct position. not a big deal if no asymmetrical collapse, scoliosis, or vert body rotation etc. but if those are present and each level has to be set up really individually on AP and lateral, it has been more trouble than it’s worth. The time I seem to have gained setting up the next level is then lost repositioning the C-arm for the prior level
All that being said, I am not the most experienced in the world on this, trying to learn more every case I do. Interested in hearing others opinions
