Traumatic atlantooccipital dislocation: two cases with survival.
نویسندگان
چکیده
These two cases with long-term survival after anterior and posterior AO dislocation point out the importance of making the diagnosis. Our simple technique of rapid CT confirmation of AO dislocation is a practical adjuvant procedure, particularly in patients with suspected intracranial injury.

Traumatic atlantooccipital dislocation with survival.
Traumatic atlantooccipital dislocation is generally considered incompatible with life. However, there have been isolated survivals from this injury, and a few patients initially have minimal neurologic deficits disproportionate to the gravity of their injury, a feature that has not been adequately stressed. The potentially catastrophic results of delayed therapy make early radiographic detectio...
متن کاملEarly Identification of Traumatic Durotomy Associated with Atlantooccipital Dislocation May Prevent Retropharyngeal Pseudomeningocele Development
Atlantooccipital dislocation can be complicated by a traumatic durotomy that may lead to the rare development of a retropharyngeal pseudomeningocele. To our knowledge this has been reported only five times previously. We present the case of a 60-year-old man involved in a motor vehicle accident who suffered an atlantooccipital dislocation and C5-C6 three-column injury. A unique MRI image of a d...
متن کاملTraumatic dislocation of the atlanto-occipital joint.
We present four patients who had sustained a traumatic dislocation of the atlanto-occipital joint. The diagnosis was initially missed in two patients. One patient, who was neurologically intact, was treated non-operatively. The remaining three recovered neurologically after an occipitocervical fusion. Early recognition of the injury, especially in multiply-injured patients with head injuries, a...
متن کاملTraumatic avulsion fracture of the occipital condyles and clivus with associated unilateral atlantooccipital distraction.
We describe an unusual tramatic fracture/distraction injury of the craniovertebral junction, which the patient survived. It is postulated that this represents an example of the spectrum of fracture dislocation injuries that may occur at, and adjacent to, the atlantooccipital joints. Avulsion fractures in this region , associated with atlantooccipital dislocation, may be more common than previou...
متن کاملEvaluation of traumatic atlantooccipital dislocations.
The diagnosis of traumatic atlantooccipital dislocation (AOD) from the cross-table lateral radiograph is difficult because of problems in demonstrating the complex anatomy of this area and the intricate radiographic methods used to diagnose AOD. Although CT or polytomography seem to be the most accurate diagnostic methods, it is often the lateral radiograph from which the diagnosis and further ...
