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.

Atlantoaxial rotatory fixation (AARF) in adult is a rare disorder that occurs followed by a trauma. The patients were presented with painful torticollis and a typical 'cock robin' position of the head. The clinical diagnosis is generally difficult and often made in the late stage. In some cases, an irreducible or chronic fixation develops. We reported a case of AARF in adult patient which was treated by immobilization with conservative treatment. A 25-year-old female was presented with a posterior neck pain and limitation of motion of cervical spine after a traffic accident. She had no neurological deficit but suffered from severe defect on the scalp and multiple thoracic compression fractures. Plain radiographs demonstrated torticollis, lateral shift of odontoid process to one side and widening of one side of C1-C2 joint space. Immobilization with a Holter traction were performed and analgesics and muscle relaxants were given. Posterior neck pain and limitation of the cervical spine's motion were resolved. Plain cervical radiographs taken at one month after the injury showed that torticollis disappeared and the dens were in the midline position. The authors reported a case of type I post-traumatic AARF that was successfully treated by immobilization alone.

An irreducible atlanto-axial rotatory dislocation(so-called fixation) is an extremely rare deformity. Its stricking features are the delay in diagnosis and the persistent clinical and roentgenographic deformities. The diagnosis is suggested by the plain roentgenograms and is confirmed by operation. A 9 year-old boy having the atlanto-axial rotatory fixation was examined at Pohang St. Mary's Hospital in July 1985 and was treated with skull traction followed by Gallie fusion. He was followed up over a year, and had satisfactory result at last follow-up.
