This is most readily appreciated on the open mouth view which shows that the lateral masses of C1 no longer align with the lateral masses of C2, and that the spaces between the peg and the C1 lateral masses are widened. The ring expands and loses alignment with the adjacent occipital bone above, and C2 below. Injury to C1(atlas) results in loss of integrity of its ring structure. This page describes typical appearances of some common C-spine fractures. To project the intervertebral disc spaces open, the central ray should be directed perpendicular to the long. This angle can and will vary between 5-20 depending on the position of the head. laterally to include the mandible superior-inferior to include the upper incisors and lower incisors orientation. For this reason, a cephalic angle is required to project through the long axis of the vertebral column. the central ray is centered at the center of the open mouth angle accordingly see 'patient positioning' collimation. As technology advances, computed tomography has replaced this projection, yet there remain many institutions (especially in rural areas) where computed tomography is not. Cervical spine swimmer's lateral view is a modified lateral projection of the cervical spine to visualize the C7/T1 junction. Bones - Cortical outline/Vertebral body heightĬervical spine injuries often have characteristics which depend on the mechanism of injury. A lordotic curvature exists in the cervical spine. Citation, DOI, disclosures and article data.Remember, you need all three views (lateral, AP and odontoid/open mouth view) for an adequate study. Alignment - Anterior/Posterior/Spinolaminar The ABCs of the cervical spine provide a helpful mnemonic to guide the systematic assessment of these x-rays.Look at all views available in a systematic manner X-Ray Cervical Spine AP & LAT View test is used to visualize the first seven vertebral bones (C1 - C7) of the spinal column (backbone) located in the neck.Clinical considerations are of particular importance when assessing appearances of C-spine X-rays. b Flexion view: subluxation of C2 over C3 with local kyphosis of 20°. a Lateral radiographic view of the cervical spine. Due to the angled, divergent nature of the x-ray beam, the area. Case of a 10-year-old boy with persistent neck pain 3 months following a cervical spine trauma.
