Atlantoaxial rotation dislocation fixation

The essence of atlantoaxial rotation dislocation is the old dislocation. Fielding (1977) refers to the atlantoaxial rotational subluxation that occurs spontaneously or after minor trauma as atlantoaxial rotational fixation. In the future (1983) he was also called spinal dislocation. Atlantoaxial joint dislocation and fixation is a clinical manifestation of idiopathic torticollis, head and neck stiffness, and rotation limitation. The corresponding joints of the dentate process and the atlas lateral mass are changed to X-ray features. Often misdiagnosed due to clinical neglect.
