- W2275146525 abstract "Background: Imaging-guided surgery provides intraoperative realtime navigation for spinal surgery to prevent neurovascular injury. However, the initial experience of O-arm three‑dimensional (3D) navigation is less clarified. The study aims to evaluate the accuracy of O-arm 3D navigation-assisted spinal implantation. Materials and Methods: Total 118 transpedicle/lateral mass screws in 17 consecutive patients performed through O-arm 3D computed tomography (CT) imaging navigation. Screws accuracy, Visual analogue scale (VAS), and operation time were assessed. O-arm 3D navigation included 96 pedicle screws and 22 lateral mass screws. Results: There accuracy rate of screw implantation was 96.6% (114/118) without breach (Grade 0), whereas 3.4% (4/118) breach between 2 and 4 mm (Grade 2). In the cervical spinal, 12 pedicle screws were placed in 4 patients; 16.7% (2/12) exhibited a Grade 2 breach in one patient, who developed a new neurological deficit and required revision. In the lumbosacral spine, 2.78% (2/72) exhibited a Grade 2 breach in 2 patients. The mean ± standard deviation VAS of the patients in postoperative and preoperative status was 1.47 ± 0.50 and 3.58 ± 1.00, respectively. The operation time was significantly longer in O-arm navigation than in C-arm guidance (426.5 ± 180.4 vs. 317.9 ± 133.6 min, P ＜ 0.05). Conclusion: O-arm 3D navigation achieves a relatively high accuracy of pedicle and lateral mass screws implantation. The accumulation of experience for O-arm 3D CT during initial learning curve is still warranted to promote the accuracy of screws position and shorten operation time." @default.
