[Head and brain injuries in bicyclists]

44 patients were hospitalized for neurosurgical care after bicycle accidents during a period of 50 months. Ten times as many were injured in other types of road accidents. 42 of the 44 cases had brain injury, with a mean hospitalization of 9.7 days. A third needed operation and a fourth were discharged with residual neurological deficits. The low incidence of 0.95 cases per 100,000 per year led us to examine the factors which limit the use of bicycles in our region. The severity of the injuries in our cases was much greater than in those in other countries, with a mean injury severity score of 14.2. None of our cases had worn a protective helmet, and we join in the world-wide plea for an educational campaign for their use.
