Abstract
The atlantoaxial (AA) segment is the most mobile region of the spinal column. Approximately 50% of the cervical spine’s rotary movement, and as much as 50 degrees of its rotation, occurs at the C1-C2 joint [1,2]. Instability of this joint can result from various processes, including aplasia or hypoplasia of the odontoid process, laxity of the transverse ligament and assimilation of the atlas. AA instability is associated with various conditions including Down’s syndrome, Klippel-Feil syndrome, osteogenesis imperfecta, neurofibromatosis and rheumatoid arthritis (RA) [3-6].
