Application of automated pedicle screw planning system in robot-assisted lumbar pedicle screw fixation
摘要
Abstract
Objective:To investigate the application of an automated pedicle screw planning system in robot-assisted lumbar spine surgery.Methods:Clinical data of 45 patients who underwent robot-assisted posterior lumbar pedicle screw fixation using an automated planning system based on intraoperative O-arm cone-beam computed tomography(CBCT)images at the Department of Orthopedics,the First Hospital of China Medical University from June 2024 to February 2025 were retrospectively analyzed.Screw planning accuracy was assessed using the Gertbein-Robbins grading system.Screw trajectories from manual annotation and automated planning were compared.Planning time and screw adjustment rates were recorded.Results:A total of 232 screws were successfully planned.Among normal vertebrae,216 screws were acceptable,achieving a planning accuracy of 99.08%.Among fractured vertebrae,10 screws were acceptable,with a planning accuracy of 71.43%.No statistically significant difference was found between manual annotation and automated planning of screw trajectories(P>0.05).The average screw planning time was(8.29±0.53)s.137 screws were adjusted in normal vertebrae(adjustment rate:62.84%),and 12 screws were adjusted in fractured vertebrae(adjustment rate:85.71%).Among these adjustments,143 screws were modified in the transverse plane(adjustment rate:61.64%),while 6 screws were adjusted in the sagittal plane(adjustment rate:2.59%).Conclusion:The automated pedicle screw planning system used in this study can achieve high accuracy in lumbar pedicle screw placement while significantly reducing planning time,which is worthy of clinical promotion.关键词
