“…For example, the rate of osteoarthritis in atlanto-dental joint was 88-90% in the age group older than 60 years, and that likely explains atlanto-dental joint narrowing with increasing age (20,21). A variety of normative data is available in the literature using radiography and MDCT (3,4,8,14,16,25,26) A scatter diagram was plotted according to the data in our research (Fig. 3).…”

“…Bony anatomy, injury, and lesions are displayed more clearly on MDCT than radiography or magnetic resonance imaging (MRI) (11)(12)(13). The normative values of ADI in healthy children and young adults have been assessed on MDCT (3,4,14,15). However, the modality has not been used to measure the normal ADI among all ages in adults.…”

“…However, other studies also used normal CT findings and no evidence of cervical spine injury on emergency department discharge as tools for confirming "no injury." 19 MR imaging is an expensive tool, and screening every patient with cervical spine trauma by using MR imaging is not justified. We additionally confirmed clearance of cervical spine injury on a clinic follow-up visit in our noninjured group.…”

“…The basion-dens distance is a reliable imaging method to detect AOD. A distance greater than 10 mm is highly suggestive of dissociation (17,36). The ligamentous complex provides most of the stability at the atlanto-occipital joint, as there is otherwise not much inherent osseous stability at this joint.…”

Imaging of Atlanto-Occipital and Atlantoaxial Traumatic Injuries: What the Radiologist Needs to Know

Approximately one-third of all cervical spine injuries involve the craniocervical junction (CCJ). Composed of the occiput and the first two cervical vertebrae, this important anatomic landmark, in conjunction with an intricate ligamentous complex, is essential to maintaining the stability of the cervical spine. The atlantoaxial joint is the most mobile portion of the spine, predominantly relying on the ligamentous framework for stability at that level. As acute onsite management of trauma patients continues to improve, CCJ injuries, which often lead to death onsite where the injury occurred, are increasingly being encountered in the emergency department. Understanding the anatomy of the CCJ is crucial in properly evaluating the cervical spine, allowing the radiologist to assess its stability in the trauma setting. The imaging findings of important CCJ injuries, such as atlanto-occipital dissociation, occipital condyle fractures, atlas fractures with transverse ligament rupture, atlantoaxial distraction, and traumatic rotatory subluxation, are important to recognize in the acute setting, often dictating patient management. Thin-section multidetector computed tomography with sagittal and coronal reformats is the study of choice in evaluating the extent of injury, allowing the radiologist to thoroughly evaluate the stability of the cervical spine. Furthermore, magnetic resonance (MR) imaging is increasingly being used to evaluate the spinal soft tissues and ligaments, and to identify associated spinal cord injury, if present. MR imaging is also indicated in patients whose neurologic status cannot be evaluated within 48 hours of injury. .

Evaluation of the C1–C2 Articulation on MDCT in Healthy Children and Young Adults

Abstract: We propose that the obtained normal values be considered as the upper limits of the normal range for the atlantoaxial interval in adult and pediatric populations on MDCT images.
