Dr. Raiszadeh explains how O-arm®-assisted spine surgery compares to traditional back surgery.
With the advent of the O-arm® and the introduction of the O-arm® to our hospital, at Alvarado Hospital here in East County San Diego, we have been able to use this for all of our cases that we place implants in. Now what are the implants? Now the implants can range from cervical disc replacements, cervical fusions to thoracic fusions to even lumbar fusions, specifically which we’ve used this O-arm® for are for the lumbar interbody fusions, for example, the TLIF procedure and the PLIF procedure.
These procedures mandate several different steps that allow you to fuse two bones together. When you fuse two bones together you have to place screws in a very confined space. The accuracy is mandated because if you go too far medial, which is inside, or too far lateral, which is outside, or too far inferior, which is south, you can hit nerves, blood vessels, arteries. The O-arm® helps me make sure that when I am placing these screws it’s 100% as accurate as I can get it.
Now, placing the screws is not the only thing we do, but putting the interbody cages between the vertebral bodies is another part of that procedure. Now in those cages we put bone graft and the accuracy of placing the cage in between those bones allows us to retain the normal alignment, which is called lordosis in the lumbar spine, in addition to be able to pack bone between those bones, which just allows us to have fusion.
So traditionally we have been using the fluoroscopy, which is very good. However, using the intraoperative CT scan is the most accurate way to assess for placement of implants, either pedicle screws or interbody cages within the lumbar spine.
