Value of the swimming position and arm traction in visualizing the cervicothoracic junction over the standard lateral cervical X-ray.

Background: The cervicothoracic junction (CTJ) is often inadequately visualized on lateral cervical X-rays due to anatomic variations and technical factors.

Aims: The aim of this study was to investigate whether the swimmer's view and arm traction could enhance the image field on the standard lateral cervical (SLC) X-ray.

Methods: The study was conducted in a university hospital in October 2007 with 40 volunteers.
