In this video from Open Operating Theatre, Jean-Charles LeHuec, MD, from Bordeaux University Hospital in Bordeaux, France, performs a pedicle subtraction osteotomy in a man who could not stand straight because of sagittal imbalance and regularly compensated for that when standing and walking.
In the video, LeHuec uses navigation to insert the screws and ensures these are positioned appropriately. He emphasizes the importance of the sacral fixation and plate insertion, which involved placement of four screws in the sacrum.
The osteotomy done inside the pedicle of interest is performed with an egg-shell technique that uses a navigation probe, which helps LeHuec tell exactly where inside the body he is working. If the curvature of the initial rod is inadequate, he demonstrates how the rods can be replaced intraoperatively with smaller ones that may allow for the application of increased compression, which will increase the fixation of the screws.
This video is a teaching tool to help surgeons prepare for surgery or they can use it as refresher on the surgical technique and indications for this surgery.
