Posterior displacement of the odontoid after fracture occurs much less frequently than does anterior displacement. Experience with four patients suggests that anatomic reduction may not be possible and prolonged attempts to gain reduction are not advisable. Those cases should be managed with early application of a halo vest. A rotating frame should be avoided. The potential for respiratory arrest, at least in the older individual, is great and can be precipitated even by a change of position in the process of turning on the rotating frame. The mechanism of the respiratory failure is obscure.
齿突骨折后向后移位的发生率远低于向前移位。对4例患者的经验表明，解剖复位可能无法实现，长时间尝试复位并不可取。这些病例应早期应用头环背心进行治疗。应避免使用旋转床。呼吸骤停的可能性很大，至少在老年人中如此，甚至在旋转床上翻身过程中改变体位都可能引发呼吸骤停。呼吸衰竭的机制尚不清楚。
