Three-dimensional (3D) image guidance technology is gaining popularity in spine surgery. The O-Arm navigation platform, which relies on cone-beam CT images acquired in the operative position, represents the most recent advancement in this field. We report our technique for MIS pedicle screw insertion using the O-Arm system and present two illustrative cases. We used percutaneous technique for short construct cases and "transfascial" technique for long-construct cases. O-Arm based navigation in minimally invasive spine surgery is safe and feasible. This technology may improve surgical accuracy and clinical outcomes but long term prospective studies are needed to validate this.
三维（3D）图像引导技术在脊柱手术中越来越受欢迎。O型臂导航平台依赖于在手术体位获取的锥形束CT图像，代表了该领域的最新进展。我们报告了使用O型臂系统进行微创椎弓根螺钉植入的技术，并展示了两个说明性病例。对于短节段固定病例我们采用经皮技术，对于长节段固定病例采用“经筋膜”技术。基于O型臂的导航在微创脊柱手术中是安全可行的。这项技术可能会提高手术准确性和临床效果，但需要长期前瞻性研究来证实这一点。
