[Chance fracture: a report of 3 cases and observations on the mechanisms of injury].
Three cases of Chance fracture were reported. Hoping to clear up the non-unanimous explanations of injury mechanism of Chance fracture, we worked on 4 patterns of model we designed to demonstrate the way this sort of fracture occurs. It came to the conclusion that at the moment of accident, the force acting on a flexed spine violebtely bends it further, causing fracture of the anterior column with or without compression, and tension splitting or horizontal fracture of the posterior column; at the same time, if the mid-column in between, the fulcrum, is also injured and shifted foreward, a Chance fracture is then well produced.
