OBJECTIVE
We compared the accuracy of C-arm fluoroscopy versus O-arm-assisted pedicle screw (PS) placement in the cervicothoracic spinal junction (CTSJ).
METHODS
Patients who underwent PS placement in the CTSJ (C7-T4) at our hospital were included in this study. Of 37 patients who underwent PS placement in the CTSJ, 20 underwent intraoperative C-arm fluoroscopy-assisted surgery (C Group) and 17 underwent intraoperative O-arm-assisted surgery (O Group). In total, 159 PSs were placed-73 in the C Group and 86 in the O Group. The accuracy of PS placement was compared between the C Group and O Group using the classification proposed by Gertzbein and Robbins to analyze pedicle violation.
RESULTS
PS accuracy was higher in the O Group than C Group; PS placement evaluated as grade A, representing no perforation, was 95.3% (82/86) for the O Group, whereas it was 78.1% (57/73) for the C Group. There was a clear statistically significant difference in accuracy of PS placement between the groups (P = 0.0013).
CONCLUSIONS
O-arm-assisted surgery improved the accuracy of PS placement in the CTSJ.
目的
比较 C 臂透视与 O 臂辅助椎弓根螺钉（PS）置入术在颈胸脊柱交界区（CTSJ）的准确性。
方法
本研究纳入在我院行 CTSJ（C7-T4）PS 置入术的患者。37 例患者行 CTSJ 内 PS 置入术，其中 20 例行术中 C 臂透视辅助手术（C 组），17 例行术中 O 臂辅助手术（O 组）。共置入 159 枚 PS，C 组 73 枚，O 组 86 枚。采用 Gertzbein 和 Robbins 提出的分类标准分析椎弓根穿孔情况，比较 C 组和 O 组 PS 置入的准确性。
结果
O 组 PS 准确性高于 C 组；O 组 PS 分级为 A 级（无穿孔）的比例为 95.3%（82/86），C 组为 78.1%（57/73），两组间 PS 置入准确性差异有统计学意义（P=0.0013）。
结论
O 臂辅助手术提高了 CTSJ 内 PS 置入的准确性。
