Spinal injury after ejection in jet pilots: mechanism, diagnosis, followup, and prevention

In order to contribute to the study of spinal injury after ejection., the author analyzed the results of 100 cases of ejections carried out by military and civil Italian jet pilots in a period of 20 years. Of this group, 47 successfully ejected from aircraft without injury; 11 ejections proved fatal. The remaining 42 pilots sutained vertebral fractures, while 27 sustained other traumatic injuries different from spinal fractures. There were 23 vertebral fractures in 15 pilots and the most frequently affected vertebrae were those of the thoraco-lumbar junction. Analysis was make of the pathology, the clinical and radiological profiles, the therapeutic treatment, and the relative aeromedico-legal aspects concerning the temporary unfitness for flying or permanent grounding of the personnel as well as the possible prevention of spinal injury after ejection
