Minor head trauma in the child, whether accidental or inflicted, is a frequent reason for seeking medical attention. Our aim is to describe the characteristics of minor head trauma in children aged 0-3 years and the resulting injuries. This in order to help the clinician to suspect and thelegal expert to confirm intentional abuse. Children aged from 0 to 3 years with minor head trauma and attending the pediatric emergency department were included in the study between January 2013 and June 2014. The correlation between the characteristics of trauma and the resulting injuries was analyzed using a prospective data collection questionnaire completed by the physicians who cared for the child. A total of 709 children with minor head trauma were included in the study. In nearly 90% of cases, fall height was less than 1 m. Only one-third of children aged less than 6 months had external head injury. Low-intensity trauma, such as a low-velocity fall from a height of less than 1.5 m does not cause intracranial injury. External injuries were more frequent in children who had a fall with an anterior impact, while internal injuries were found only in posterior and lateral impacts. In the context of minor head trauma, the physician must be vigilant and must ask for a full and clear description of the trauma, its mechanisms and other characteristics, when external or internal head injuries are observed in children aged less than 6 months.
