atlantoaxial subluxation

Orthopedics An upper cervical spine subluxation which is either rotatory or anterior; rotatory AAS is more common in children, often due to apparently trivial injury; torticollis may be seen Imaging On an open mouth film, the odontoid is not equidistant between lateral masses of C1 Management Reduce subluxation and brace; recurrent or chronic cases can be treated with C1-C2 fusion; anterior AAS is due to traumatic disruption of transverse ligament Imaging Abnormal atlanto-dental interval; if anterior AAS is suspected, a CT rules out fracture; an MRI is used to evaluate the transverse ligament which, if disrupted, requires fusion; a cervical brace suffices for fracture without disruption. See Atlantodental interval.

Risks of general anaesthesia include the difficulties of tracheal intubation and the potential complications encountered in vascular EDS patients (i.e., arterial dissection/cerebral hemorrhage during hypertensive response to intubation, possible pneumothorax from positive pressure ventilation, and unstable cervical spine with potential for atlantoaxial subluxation) [3, 7, 8].

In another rare situation, fusion of the lower cervical spine in DISH is possibly associated with enhanced mechanical stress at the craniocervical region, which could lead to soft tissue mass, odontoid fracture, atlantoaxial subluxation, and pseudotumor and then cause severe spinal cord lesion.[sup][2] In the current case, there was no obvious spinal stenosis or craniocervical abnormality.
