Serious head injury in infants: accident or abuse?

The medical records and computed tomography (CT) scans of all children less than 1 year of age admitted to the hospital with head injury over a 2-year period were reviewed. Sixty-four percent of all head injuries, excluding uncomplicated skull fracture, and 95% of serious intracranial injuries were the result of child abuse. The occurrence of intracranial injury in infants, in the absence of a history of significant accidental trauma, such as a motor vehicle accident, constitutes grounds for an official child abuse investigation.
