Atlantoaxial Instability: Evolving Understanding

Part of the Acta Neurochirurgica Supplement book series (NEUROCHIRURGICA, volume 125)


The atlantoaxial joint is the most mobile joint in the body. The physical architecture of the joint is characterized by a uniformly round and approximately flat surface, which allows a wide range of unobstructed movements. The standing human posture and lifelong heartbeat like uninterrupted activity of the atlantoaxial joint, and its ability to facilitate saying both ‘yes’ and ‘no’ necessarily requires smooth and ‘fluid’ movements that are supported by strong yet supple ligaments. The magnificent architectural structure that is ‘magically’ designed and carved by nature to provide both stability and mobility and to allow a smooth and safe transit passage for the most critical neural and vascular structures can only be admired in awe and appreciated.
