Violent shaking (by parent) may cause subdural hematoma; whereas ruptured spleen occurs due to compression of abdomen; long bone fracture due to compression, bending, direct blow, pulling and twisting; and skull fractures due to direct blow. Caffey (1974) described the effects of shaking as a major cause of subdural haematoma and intraocular bleeding in battered babies or infantile whiplash syndrome.
