AbstractOdontoid process fractures are frequent injuries of the cervical spine and usually occur at an advanced age and often due to minor trauma. In younger patients they are mainly observed in the context of high impact trauma. Odontoid fractures are classified according to Anderson and D'Alonzo. In rare cases the fracture results in cervical myelopathy, which can be life-threatening.In this article, two cases of patients with odontoid fractures and traumatic myelopathy are presented. The first case concerns a type III fracture, the second a type II fracture. In both cases the instability present was incorrectly assessed on the basis of the anatomical position in the initial computed tomography (CT). In the further course both cases showed considerable instability, which led to fatal spinal cord injuries.The purpose of this case report is to draw attention to the possible presence of spinal cord injuries in supposedly trivial odontoid fractures when high speed trauma has occurred. In particular, spinal cord compression should be considered in patients requiring resuscitation without having an internal medical cause. If the patient with a bone injury on CT, e.g. cannot be adequately assessed clinically by intubation, the indications for magnetic resonance imaging must be generously considered. This is the only way to ensure early detection of a myelopathy and timely treatment.© 2021. The Author(s).
