Efficacy and Safety of Virtual Surgery Plan and 3D Printing Guide Plate Assisted Atlas Lateral Mass Combined with Axis Pedicle Screw in the Treatment of Atlantoaxial Instability
Objective To investigate the clinical efficacy and safety of virtual surgery plan and 3D printing guide plate assisted atlas lateral mass combined with axis pedicle screw placement in the treatment of atlantoaxial dislocation.Methods A retrospective analysis was performed on 19 patients with atlantoaxial instability who underwent atlantoaxial lateral mass combined with axial pedicle screw placement and internal fixation in Jining First People's Hospital from January 2019 to December 2022.Among them,9 patients were treated with virtual surgery plan and 3D printing guide plate-assisted screw placement(3D printing group),and 10 patients were treated with traditional surgical screw placement(traditional group).The perioperative indicators,screw placement accuracy and clinical efficacy indicators were compared between the two groups.Results The operation time,intraoperative blood loss,intraoperative fluoroscopy times and excellent and good rate of screw placement in the 3D printing group were lower than those in the traditional group,and the differences were statistically significant(P＜0.05).There were significant differences in VAS score and JOA score between the two groups at 7 days after operation(P＜0.05).There was no significant difference in postoperative complications and JOA score improvement rate at 1 year after operation(P＞0.05).Conclusion Virtual surgery plan and 3D printing guide plate assisted and traditional surgical methods of atlas lateral mass combined with axis pedicle screw placement and internal fixation are effective in the treatment of atlantoaxial instability,but 3D printing navigation template assisted screw placement has higher excellent and good rate,shorter operation time,less intraoperative blood loss and fewer fluoroscopy times,so it has certain advantages.
