摘要
目的:探讨下颈椎的屈曲程度与后路经寰枢关节螺钉固定术的可能性。方法:回顾已施行经寰枢关节螺钉固定术病例的术前颈椎过屈位X线像,测量C2～C7间的角度,复习手术经过,分析可完成螺钉固定的颈椎曲度及其它相关因素。结果:在已完成后路经寰枢关节螺钉固定术的75例患者中有58例屈颈侧位X线像显示下颈椎呈后凸状态,后凸角平均为17.25°;另17例屈颈侧位片见下颈椎呈前凸状态,但这些病例都是体形瘦长者。结论:后路经寰枢关节螺钉固定术仅适合于下颈椎可以很好屈曲及体形瘦长的病例。
Objective：To identify the possibility of obtaining the correct screw path before operation by evaluating the flexibility of lower cervical spine.Method：Using preoperative lateral flexion films from those patients with atlantoaxial transarticular scew fixation ,the lordotic or kyphotic angle between C2 to C7 were measured, arid the recordation of operative procedure was reviewed.The alignment of cervical spine and other factors influencing the performance of Magerl technique were studied.Result：Among 75 consecutive cases with atlantoaxial transarticular screw fixation,58 cases whose lower cervical spine was kyphotic（average kyphotic angle 17.25°）,and 17 cases was lordotic with lanky body build.Conclnssion：Not all but only the cases whose lower cervical spine is kyphotic during neck flexion and the lanky patients can be fixed by atlantoaxial transarticular screw.
