A retrospective study was conducted of the 880 children with head injuries consecutively admitted to the Children's Hospital of Eastern Ontario in Ottawa from July 1976 to June 1978. It confirmed a boy:girl ratio of about 2:1, with a peak of 3.5:1 around 7 years of age. The largest number of head injuries was in children under 1 year of age. Injuries were most common in summer and spring, and most were caused by falls. The most common place for head injuries was in the home, but the single most common cause of injuries was bicycle accidents, which were responsible for 12% of all the head injuries. Skull fractures were found in 30% of all the patients. Of the 34 patients with severe head injuries 8 (24%) died, 9 (26%) had a moderate residual disability and 17 (50%) made a good recovery. There were no other deaths, so the mortality for the entire group of 880 patients was 0.9%.
