目的：减少后C1侧块椎动脉损伤的机会，采用C2椎弓根/椎弓根螺钉棒固定（Goel-Harms技术）。方法：2007年2月至2013年6月，对49例患者进行后路C1-C2固定，其中男30例，女19例，年龄12岁至82岁，后路C2螺钉的新入点为中点以下3mm。 C1-C2 关节向内侧并向下进入 C2 体，可能避开椎动脉。由于螺钉现在绕过了椎弓根/椎体，损伤椎动脉的机会可能会减少。结果：无一例术中椎动脉损伤。结论：C2螺钉固定新技术可以刚性固定C1-C2关节，且没有明显的椎动脉损伤风险。
Objective: To reduce the chance of vertebral artery injury in posterior C1 lateral mass and C2 pedicle/pars screw-rod fixation (Goel-Harms technique).Method: 49 patients, 30 males and 19 females, 12years - 82 years, underwent posterior C1-C2 fixation from February 2007 till June 2013. A new entry point for the posterior C2 screw, 3mm below the midpoint of the C1-C2 joint which is directed medially and downwards into the C2 body, probably avoids the vertebral artery. As the screw now bypasses the pedicle/pars, the chance of injuring the vertebral artery is probably reduced.Results: No case of intra-operative vertebral artery injury.Conclusion: The new technique of C2 screw fixation allows rigid immobilization of the C1-C2 joint without significant risk of vertebral artery injury.
