Abstract: The X-ray exposure in lateral projection of the cervical spine region of a traumatized patient resting on a trauma board or like emergency carrier is facilitated by an applicance in the form of a traction board having a flat base plate adapted to fit in telescoping relation slidingly beneath an end portion of the trauma board and an integral upstanding traction plate projecting upwardly from the base plate for abutting contact with the end edge of the trauma board or other carrier. The traction board is equipped with e.g. a belt or a C-shaped channel for engaging the same to an overlying portion of the trauma board.
