In 1974, Caffey suggested the label "whiplash shaken infant" to describe infants who had subdural haemorrhages without evidence of external injury.1 Much has been learned about inflicted head injury since that time. In September 2001 a conference was held in Sydney to share this knowledge among people from many disciplines who work with, or are affected by, children thought to have been injured in this manner. It was jointly organised by the US National Center on Shaken Baby Syndrome, the Children's Hospital, Westmead, and the Sydney Children's Hospital, Randwick.
