ABSTRACT
Rotatory fixation of the atlantoaxial joint is relatively rare in adults but somewhat more common in children. Most of them are reduced spontaneously or after traction. However, combined rotatory injury of atlantoaxial joint and unilateral occipitoatlantal subluxation is a rare disease, and it is often difficult to diagnose accurately. Because the craniovertebral junction is complex and patients with combined atlantoaxial rotatory fixation (AARF) and occipitoatlantal subluxation has a less rotated head than patients with pure AARF. And injury of the occipitoatlantal and atlantoaxial joint can often result upper cervical instability, so early diagnosis is very important. We present a case of the combined AARF and unilateral counter occipitoatlantal subluxation after minor trauma.

Traumatic atlantoaxial rotatory fixation (AARF) with accompanying odontoid and C2 articular facet fracture is a very rare injury, and only one such case has been reported in the medical literature. We present here a case of a traumatic AARF associated with an odontoid and comminuted C2 articular facet fracture, and this was treated with skull traction and halo-vest immobilization for 3 months. After removal of the halo-vest immobilization, his neck pain was improved and his neck motion was preserved without any neurologic deficits although mild torticolis was still observed in closer inspection.
