Anterior screw fixation of Type II odontoid fractures provides immediate stabilization of the cervical spine while preserving C1-2 motion. This technique has a high fusion rate, but can be technically challenging. The authors identify key points that should be taken into account to maximize the chance for a favorable outcome. Keys to success include proper patient and fracture selection, identification of suitable screw entry point and correct screw trajectory, achieving bicortical purchase, and placing 2 screws when feasible and applicable. The authors review the operative technique and present guidance on appropriate patient selection and common pitfalls in anterior screw fixation, with strategies for avoiding complications.
II 型齿状突骨折的前路螺钉固定可在保持 C1-2 运动的同时即刻稳定颈椎。该技术融合率高,但技术难度大。作者确定了一些关键点,这些点应考虑在内,以最大限度地提高有利结果的机会。成功的关键包括:合适的患者和骨折选择、合适的螺钉入点和正确的螺钉轨迹识别、实现双皮质固定,以及在可行和适用的情况下放置 2 枚螺钉。作者回顾了手术技术,并就前路螺钉固定的合适患者选择和常见陷阱提供了指导,包括避免并发症的策略。
