Abstract：Atlantoaxial dislocation is more common in the upper neck trauma, failed to timely diagnosis and treat-ment often progression, oppressive cervical spinal life-threatening. Daily work, common due to insufficient understanding of imaging findings of atlantoaxial rotatory subluxation and lead to misdiagnosis and missed diagnosis, delay treatment. In view of this, accurate understanding of X-ray and CT manifestations, on five points of lateral atlantodental space , bilateral lateral shape and size in coranary plane, bilateral atlantoaxial lateral space, bilateral lateral joint relations, and atlanto-den-tal interval, of the normal atlantoaxial vertebral neutral position, relative parallel translation and the normal rotation, the atlantoaxial dislocation in various types,help to improve the diagnostic accuracy.
