While previous studies have examined AI-generated residency statements, their role in spine fellowship applications remains unexplored.MethodsNine personal statements (4 ChatGPT-generated, 5 human-authored) were evaluated by 8 blinded reviewers (6 attending spine surgeons and 2 fellows).

Still, the use of larger screws has biomechanical advantages. Intraoperative 2D and 3D imaging, and navigation guidance can be used to combine both goals. The aim of this study was to compare the screw diameter/pedicle width ratio (SPR) and the screw placement accuracy for 3D controlled fluoroscopy-guided pedicle screw placement vs computer navigated transpedicular screw placement in the thoracic and lumbar spine.Methods200 cases of thoracic and lumbar pedicle screw placement, of which 100 cases were performed using intraoperative computer navigation and 100 cases were performed using fluoroscopy-guidance were retrospectively registered. In the fluoroscopy group, intraoperative 3D scans were performed to confirm implant position and allow for potential intraoperative revision. In addition to accuracy and SPR, demographics, dose reports, and procedure times were analyzed.ResultsOverall, 716 fluoroscopy-guided screws were compared with 740 screws placed using navigation. Screw accuracy (83.2% vs 90.5%; <i>P</i> = .001) and SPR (0.85 ± 0.17 vs 0.88 ± 0.21; <i>P</i> < .001) were significantly higher using navigation compared to fluoroscopic guidance.
