#X RAY CERVICAL SPINE FREE#

If teeth are superimposed over the upper aspect of the dens, the head needs to be hyperextended or in the case of trauma, the central ray should be angled cephalic. Positional errors Teeth superimposing the dens make sure that any removable artifacts such as earrings, glasses or metal dentures are removed to avoid obscuring the anatomy of interest.the zygapophyseal joint space between C1 and C2 is symmetrical.

the dens is free from superimposition of the adjacent atlas lateral masses or other tissues 2.superior-inferior to include the upper incisors and lower incisors.angle accordingly see 'patient positioning'.the central ray is centered at the center of the open mouth.do not move the head in trauma, angle the central accordingly.Ankylosing spondylitis (less commonly known as Bechterew disease or Marie Strmpell disease ) is a seronegative spondyloarthropathy, which results in fusion (ankylosis) of the spine and sacroiliac (SI) joints, although involvement is also seen in large and small joints. the head should be positioned so the lower margin of the upper incisors and the base of the skull are perpendicular to the image receptor Citation, DOI, disclosures and article data.at the last instant, the patient is instructed to open their mouth as wide as possible.patient’s shoulders should be at equal distances from the image receptor to avoid rotation, the head facing straight forward.patient positioned erect in AP position unless trauma the patient will be supine.This view focuses primarily on the odontoid process of C2, and is useful in visualizing odontoid and Jefferson fractures.
