THEORY ON THE MECHANISM OF VERTEBRAL INJURIES SUSTAINED ON EJECTIONS FROM AIRCRAFT

Abstract

Vertebral injuries result from the concentration of ejection force on the front of the vertebral bodies. This is brought about by spinal flexion, the major causes of which are thought to be: (1) the deviation of ejection and vertebral axes; and (2) forward leverage of the pelvis by the inertia of the legs. If the body must be supported by the spinal column during ejection, it is important to maintain: (1) The normal vertebral alignment; (2) The normal spinal axis; and (3) Parallel ejection and vertebral axes. This will result in good body posture and therefore good force distribution on the weight-bearing portions of the vertebrae. (Author)
