4. Crushing
Being crushed can also cause comminuted fractures. Here, large amounts of force and stress are placed on the bones. This can either crush the bone from either side, or it can cause the bone to break or twist where the pressure isn’t evenly distributed.
Actually, a crushing fracture is a separate “type” of fracture in its own right, known as a compression fraction. However, if this crushing should cause mass splintering, or if it should bend the long bones in multiple places, then it can result in a comminuted fracture.
Common causes of crushing pressure include grappling in fights and in sports, as well as car accidents, or even being crushed by heavy machinery and objects.
