ABSTRACT
Positioning for lateral supine cervical spine projection. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315382210/8ca82e7c-bd07-4171-b4f5-ebaded57b5b3/content/fig2_11a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
This projection is normally undertaken on trauma patients who arrive in a supine position on a trolley or bed.
It is vitally important for the patient to depress the shoulders as much as possible (assuming no other injuries contraindicate this).
A cassette should be supported vertically or placed in the erect cassette holder, with the top of the cassette at the same level as the top of the ear. Alternatively, a vertical DDR system is employed that is adjusted along with the position of the trolley to ensure that the cervical spine corresponds to the central field of the detector.
To maximally depress the shoulders, one or two suitably qualified individuals can apply caudal traction to the arms.
