Roentgenograms were made of two patients with acute dislocations of the
cervical spine who were undergoing treatment on Stryker frames with
cervical traction. Losses of reduction were evident when the patients were
turned from the supine to the prone position. The pulmonary vital capacity
of patients with complete traumatic quadriplegia consistently decreased
when they were turned to the prone position. Prolonged supine positioning
of patients on the Stryker frame also caused occipital decubitus
ulcers.
