Acute Traumatic Atlantoaxial Dislocation (AAD) in Adults

  • P. Suchomel

Traumatic atlantoaxial dislocation (AAD) occurs less frequently than atlanto-occipital dislocation (AOD) in adults. This usually fatal injury is commonly found as a consequence of high velocity trauma. Generally, the atlas can be displaced in any direction in respect to C2 vertebra due to traumatic impact. Frequently, the C1 dislocation is accompanied by fracture of odontoid process but also other UCS fractures can be present. AAD, as a result of pure ligamentous injury, is very rare. The treatment of this highly unstable injury is mainly surgical and often preceded by a closed reduction attempt of the dislocation.
