Movement of atlanto occipital joint
NettetGenerally, the atlantoaxial joint is accountable for half of the cervical rotational movements; while the atlanto-occipital joint is responsible for half of the flexion and extension movements of the neck. Atlas (C1) In contrast to other vertebrae, the atlas is ring-shaped without a body. NettetAtlanto-Occipital Joint. The right and left atlanto-occipital joints together form an ellipsoidal joint that allows movement in flexion, extension, and, to a lesser extent, left and right lateral flexion (Table 5-5). A little rotation also occurs between occiput and atlas (Standring et al., 2008).

Inferiorly, the movement is accommodated by the lateral atlan- to-axial joints. NettetOccipital portion of the right alar ligament tightens, with the left being slackened.

The atlanto-occipital joint may be dislocated, especially from violent accidents such as traffic collisions. This may be diagnosed using CT scans or magnetic resonance imaging of the head and neck. Surgery may be used to fix the joint and any associated bone fractures. Neck movement may be reduced long after this injury. Such injuries may also lead to hypermobility, which may be diagnosed with radiographs.
