Article Title: Augmented reality navigation with intraoperative 3D imaging vs fluoroscopy-assisted free-hand surgery for spine fixation surgery: a matched-control study comparing accuracy

doi: 10.1038/s41598-020-57693-5

Figure Lengend Snippet: Surgical workflow comparison between augmented reality surgical navigation (ARSN) and free-hand (FH) techniques for spine fixation. Anatomical identification and exposure is similar for both groups (steps 1 and 2). ARSN require an intraoperative cone beam CT (CBCT) is remotely acquired behind a lead shield for screw planning and sizing to ensure an optimized placement (step 3 of ARSN). Subsequently, instruments are navigated (a drill in the example of step 4) and a CBCT for screw placement verification is performed (step 5 ARSN). In the FH group, instruments are manually used relying on visual and tactile feedbacks (step 3 FH). X-rays are performed for screw verification (step 4 FH).

On the left, rating performed on an intraoperative cone beam CT of a patient treated with augmented reality surgical navigation (ARSN). On the right, rating performed on a postoperative CT of a patient treated with the free-hand (FH) technique.

Figure Lengend Snippet: Distribution of screws rated for placement accuracy in the augmented reality surgical navigation (ARSN) and free-hand groups per anatomical region. There was no statistical difference in the proportion of screws placed in the thoracic spine or at each level between both groups.
