Abstract: to directly compare robotic-versus fluoroscopy-guided percutaneous pedicle screw (pps) placement in thoracolumbar spine trauma with a focus on clinically acceptable pedicle screw accuracy and facet joint violation (fjv).A retrospective chart review assessed 37 trauma patients undergoing percutaneous thoracic and/or lumbar fixation.Postoperative computed tomography images were reviewed by authors blinded to surgical technique who assessed pedicle screw trajectory accuracy and fjv frequency.Seventeen patients underwent placement of 143 pps with robotic assistance (robot group), compared with 20 patients receiving 149 pps using fluoroscopy assistance (control group).Overall, the robot cohort demonstrated decreased fjv frequency of 2.8% versus 14.8% in controls (p = 0.0003).When further stratified by level of surgery (i.E.Upper thoracic, lower thoracic, lumbar spine), the robot group had fjv frequencies of 0%, 3.2%, and 3.7%, respectively, compared with 17.7% (p = 0.0209), 14.3% (p = 0.0455), and 11.9% (p = 0.2340) in controls.The robot group had 84.6% clinically acceptable screw trajectories compared with 81.9% in controls (p = 0.6388).Within the upper thoracic, lower thoracic, and lumbar regions, the robot group had acceptable screw trajectories of 66.7%, 87.1%, and 90.7%, respectively, compared with 58.8% (p = 0.6261), 91.1% (p = 0.5655), and 97.6% (p = 0.2263) in controls.There was no significant difference in clinically acceptable screw trajectory accuracy between robotic versus fluoroscopy-guided pps placement.However, the robot cohort demonstrated a statistically significantly decreased fjv overall and specifically within the thoracic spine region.Use of robotic technology may improve radiographic outcomes for a subset of patients or spine surgeries.Reported events 1.During use of the guidance system for spinal surgery to place 143 screws in 17 patients, 44 screws were deviated less than 2 mm, 17 screws were deviated between 2-4 mm, and 5 screws were deviated between 4-6 mm.
