“…AAI is most frequently seen in individuals suffering from RA, Down syndrome (DS), trauma, infections, and neoplastic processes. 1–16 In the adult population, trauma is a frequent cause for both bony and ligamentous injury of the atlantoaxial complex. Individuals with RA are at an increased risk for developing AAI, as RA is an inflammatory autoimmune disease that targets synovial joints.…”

Background and purpose The atlantal tubercle is the attachment point of the transverse atlantal ligament, the main stabilizer of the atlantoaxial complex. No system of classification of the tubercle exists in the literature. We aimed to develop a morphologically based classification system of the atlantal tubercle to aid clinicians who deal with craniocervical pathology. Materials and methods A retrospective review of computed tomography (CT) scans of the cervical spine was performed. The morphology of the atlantal tubercle was classified into four variants: rounded (classical), pointed, flattened, and hypoplastic. Age, presence, and morphological type were recorded. Results A total of 200 CT scans were identified and reviewed. The tubercle was present bilaterally in all patients. Patients were equally distributed over various age ranges. The following morphological types were recorded: rounded (227/400; 56.8%), pointed (13/400; 3.3%), flattened (126; 31.5%), and hypoplastic (34/400; 8.5%). The same type was seen bilaterally in 68% (135/200) of patients. Morphological types appear equally on the right and left side of the atlas. Conclusions The first morphologically based classification system of the atlantal tubercle utilizing CT is presented. Morphology type, especially hypoplastic type, may confer an increased risk for subsequent need for posterior fusion.

Variation of bilateral transverse ligament tubercles with age and gender in a large series of subjects on multidetector computed tomography

Abstract: The height of the transverse ligament tubercles on MDCT linearly increases with increasing age with no significant differences among the genders or the side measured.
