Fractures of the odontoid process of the second cervical vertebra can result in instability, neurological damage and death. Treatment includes conservative management (external immobilisation devices) or surgical treatment (internal fixation by posterior fusion or anterior screw fixation). To compare surgical with conservative treatment for fractures of the odontoid process. We ...

The so-called "peridentale aureole" ("crowned odontoid"), a horseshoe-like calcification around the odontoid process, can occasionally be shown on transbuccal views of the occipito-atlantoaxial region, but is commonly only seen on a.p. tomography in patients with osteoarthrosis of the anterior atlantoaxial joint. Tomographic examinations reveal that these irregular horseshoe-like calcifications around ...
