摘　　要：目的探讨术中三维C型臂实时透视导航在颈椎椎弓根螺钉植入手术中的应用。方法在导航下行颈椎椎弓根螺钉固定术22例，其中颈椎骨折9例，颈椎肿瘤4例，颈椎滑脱失稳6例，颈椎病3例。术后进行CT扫描，评估螺钉位置。结果导航下22例共植入112枚颈椎椎弓根螺钉。术后CT椎弓根位置扫描：A级，107枚（95．5％）；B级，3枚；C级，1枚；D级，1枚。术后临床无脊髓、神经和椎动脉损伤。结论术中三维C型臂实时透视导航系统可以准确引导颈椎椎弓根螺钉的植入。Objective To evaluate the accuracy of Intraoperative Iso-C3D navigation guiding cervical pedicle screw fixation. Methods Twenty-two cases adopted cervical pedicle screw fixation of cervical spine, including 9 cervical spine fractures, 4 cervical tumors, 6 cervical destabilizing, 3 cervical syndrome. The cervical pedicle screw position were assessed with post-operative CT by grade. Results One hundred and twelve screws were fixed in 22 cases successfully. Grade： 107 in A grade （95.5%）; 3 in B grade： 1 in C grade; 1 in D grade. There were not any complication. Conclusion Intraoperative Iso-C3D navigation can improve precision of cervical pedicle screw fixation distinctively.
