Abstract
Pedicle screw fixation is a lumbar spinal fusion (LSF) technique that involves the implantation of screws to act as anchor points to restrict movement between vertebrae. To improve the accuracy of these procedures, surgical robots were created to assist in spinal fusion surgery, which have reduced radiation exposure and recovery time. Our objective was to determine if robotic surgical assistance in pedicle screw implantation is within a 2mm deviation. This was assessed by overlaying the pre-op and post-op images in the Maxor X software system and measuring the deviation and angle from the planned implantation site. Preliminary results indicate that Maxor X Stealth Edition robotic guidance system is performing within the 2mm deviation in the pedicle region. These results suggest that surgical robots assisting in LSF procedures aid in accuracy of screw implantation, while lowering risk of exposure to radiation and patient recovery time.
