Research Article Incidence and Variants of Posterior Arch Defects of the Atlas Vertebra
2016Co-Authors: Hans-peter Simmen, Clément M. L. WernerAbstract:Copyright © 2013 Sebastian Guenkel et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. In order to describe the incidence and existing variants of congenital anomalies of the atlas Vertebrae in a Caucasian population, we examined 1069CT scans of the upper cervical spine.We found 41 cases with altered atlas Vertebrae, representing 3.8 % of all analyzed patients. With 83 % of all found anomalies, the predominant type is characterized by a small dorsal cleft (3.2 % of all patients). Rare varieties feature unilateral or bilateral dorsal arch defects, combined anterior and posterior clefts (0.2 % of all patients) or total erratic atlas Vertebra Malformation (0.1 % of all patients). Atlas arch defects are found nearly 4 % at the time. Most anomalies affect the posterior arch, whereas the anterior arch or both are rarely affected. Totally irregular C1 Vertebrae are extremely infrequent. 1
