Craniocervical injury

Clinical Notes

Two other persons dead on the scene.


MR – Disruption of apico-clival ligament, atlanto-axial joint fluid, elevation of tectorial membrane and precervical edema/hemorrhage. No cord contusion or edema.


The constellation of findings in this case is related to transient and incomplete atlanto-occipital dissociation. This injury is quite common in children less than 8 years of age involved in deceleration trauma because of shallow atlanto-occipital joints, lax craniocervical ligamentous support and relatively large head size. The implications are not fully known but in the absence of cord injury and frank ligamentous diruption the prognosis is probably very good.
