Differentiating pseudo-dislocation of the cervical spine from true fracture-dislocation of C2 on C3 is often difficult in children. Normal anterior position of C2 on C3 secondary to normal mobility of this area may be so pronounced that it seems true dislocation is present. A helpful line is presented to aid in the solution of this problem and the anatomy of normal and abnormal (fracture-dislocation) motion at the C2-C3 level will be discussed.
在儿童中，区分颈椎假性半脱位与C2至C3的真正骨折脱位通常很困难。由于该区域正常的活动度，C2相对于C3的正常前位可能非常明显，以至于看起来像是存在真正的脱位。本文提出了一条有用的线来帮助解决这个问题，并将讨论C2-C3水平正常和异常（骨折脱位）运动的解剖结构。
