000043559 520__ $$aInjuries of the atlas (C2) are a common, and the incidence of these fractures continues to outpace the growth rate of the aging population. C2 fractures commonly impact the odontoid process, which plays a critical role in cervical motion, allowing for 50% of axial rotation and 10-20 degrees of sagittal motion. Previous studies have shown that degenerative changes to the cervical spine, such as atlanto-dens interval, calcific synovitis, and cervical osteoarthritis are associated with dens fractures, however no research to date has shown the relationship between osteoporotic changes and susceptibility to dens fractures. While DEXA scans are the current gold standard for determining bone density, bone density can also be opportunistically measured using computed tomography using the Hounsfield Unit (HU). This study used CT to characterized vertebral body bone density and determine if there is a correlation between odontoid process bone density and occurrence of dens fractures.
