The atlantoaxial joint is a joint in the upper part of the neck between the [[atlas]] and [[axis]].

The atlantoaxial joint is of a complicated nature. It consists of no fewer than four distinct joints.

There is a pivot articulation between the [[odontoid process]] of the axis and the ring formed by the anterior arch and the [[transverse ligament]] of the atlas.

Posterior C1-C2 temporary-fixation technique can spare the [[range of motion]] (ROM) of the atlantoaxial joint after [[odontoid fracture]] healing
