BACKGROUND AND PURPOSE The ADI is the imaging diagnostic clue to AAA subluxation of the cervical spine. Some MR imaging findings other than abnormal ADI relate to AAA subluxation. However, their relationship is not yet clarified. The present study elucidates the role of MR imaging by employing these previously overlooked findings. MATERIALS AND METHODS This study enrolled 40 patients with AAA...

Between 1978 and 1988 a total of 27 operations were performed on 26 patients for cervical myelopathy due to rheumatoid disease in the subaxial spine. Three different causes were recognised: the first group had cord compression due to subluxation of the cervical spine itself (6 patients); the second had cord compression occurring from in front, with rheumatoid lesions of vertebral bodies or disc...

Clinical signs and symptoms that might predict atlantoaxial subluxation were studied prospectively in 135 of 180 children with Down's syndrome aged 6-14 years who form the Hester Adrian Research Centre cohort. Lateral radiographs of the cervical spine were taken in flexed, extended, and neutral positions, and the percentage of abnormalities in each view was 14, 10, and 10%, respectively. Gait w...

Cervical spine injuries such as subluxation and fracture dislocation have long been known to result in severe consequences, as well as the trauma management itself. The injury to the region has been identified as one of the major causes of death in Malaysian motorcyclists involved in road crashes, besides head and chest injuries (Pang, 1999). Despite this, cervical spine injury in motorcyclists...

Atlanto-axial subluxation occurs with a frequency varying from 6% to 45% in rheumatoid arthritis. Most patients are treated conservatively with a cervical collar. The effectiveness of different cervical collars in inhibiting anterior atlanto-axial subluxation was tested in 11 patients with classical rheumatoid arthritis. None of the collars had any major influence in inhibiting anterior subluxa...

OBJECTIVE To study the vertebral involvement of the cervical spine, in particular the stability of C1-C2, in children with proven Goldenhar's syndrome. DESIGN A case review. SETTING The Children's Hospital of Eastern Ontario, Ottawa. PATIENTS Eight children who had a minimum of 2 out of 3 Goldenhar criteria plus other strong associations with the syndrome and for whom detailed radiographi...

STANDARDS There is insufficient evidence to support treatment standards. GUIDELINES There is insufficient evidence to support treatment guidelines. Early closed reduction of cervical spine fracture-dislocation injuries with craniocervical traction is recommended to restore anatomic alignment of the cervical spine in awake patients. Closed reduction in patients with an additional rostral injur...

BACKGROUND Rheumatoid arthritis is sometimes associated with radiographic evidence of instability of the cervical spine, most commonly an abnormal subluxation between vertebrae. When this instability compromises the space that is available for the spinal cord, it may be predictive of paralysis. However, the prevalence of radiographic signs of instability that are predictive of paralysis among p...

The aim of the study was to evaluate the significance of odontoid lateral mass interval (OLMI) asymmetry on open-mouth view, in neck injury patients who have otherwise normal cervical spine x-rays. Thirteen neck injury patients were reviewed. Average age was 23.5 years (range, 16-30 years) and average follow-up was 15 weeks (range, 6-39 weeks). All the patients, referred from the casualty depar...
