Additional file 1: Typical case 1. Fig. S9. of 3D printing–assisted preoperative plan of pedicle screw placement for middle-upper thoracic trauma: a cohort study

A 48-year-old female suffering from traffic injury. Case1. Fig. S10. Thoracic anterioposterior X-ray revealed damage of T7 and T8 pedicle morphology as well as lateral displacement. Case1. Fig. S11. CT reconstruction confirmed T7 and T8 blowout fracture of type C. Case1. Fig. S12. Magnetic resonance imaging showed upper thoracic kyphosis and spinal cord compression. Case1. Fig. S13. Upper wall of the right T6 pedicle was pierced accidentally, and then the pedicle screw could not be satisfactorily placed even by the repeated operation. Case1. Fig. S14. Intraoperative observation of the model showed intact left pedicle in the diseased T7. On the basis of the model, screws with a diameter of 4.5 mm and length 35 mm were selected and placed in the diseased vertebra. Case1. Fig. S15. Postoperative anteroposterior X-ray prompted correction of lateral displacement of the middle-upper thoracic vertebrae. Case1. Fig. S16. Postoperative lateral X-ray prompted good placement of pedicle screws. Case1. Fig. S17. Pedicle screw distribution was of level 0 at right T5, and of level 1 at left T5. Case1. Fig. S18. Pedicle screw distribution was of level 0 at right T6. Case1. Fig. S19. Pedicle screw distribution was of level 3 at the left side of the diseased T7, piercing the lateral wall, without causing adverse consequences. Case1. (ZIP 14627 kb)本病例为1例48岁女性交通伤患者。病例1 图S10：胸部前后位X线片显示T7、T8椎弓根形态受损，伴侧方移位。病例1 图S11：CT重建（CT Reconstruction）证实T7、T8为C型爆裂性骨折。病例1 图S12：磁共振成像（Magnetic Resonance Imaging）显示上胸椎后凸畸形及脊髓受压。病例1 图S13：术中不慎穿透右侧T6椎弓根上壁，即便反复操作也无法满意置入椎弓根螺钉。病例1 图S14：术中模型观察显示病变节段T7的左侧椎弓根完整；基于该模型，选取直径4.5mm、长度35mm的螺钉置入病变椎体。病例1 图S15：术后前后位X线片提示中上胸椎侧方移位已获矫正。病例1 图S16：术后侧位X线片提示椎弓根螺钉位置良好。病例1 图S17：右侧T5椎弓根螺钉分布等级为0级，左侧T5为1级。病例1 图S18：右侧T6椎弓根螺钉分布等级为0级。病例1 图S19：病变节段T7左侧椎弓根螺钉分布等级为3级，穿透外侧壁，但未造成不良后果。本数据集附带大小为14627 kb的ZIP压缩文件。
