Cases of head injury are reviewed in which riders wearing jockey skull caps have suffered impacts to the front, back or side of their helmets. The design and constructional materials of such helmets are assessed. Impact tests that simulate the accidents confirm the low energy absorption potential of some helmets for lateral impacts. Most pedal or motorcycle helmet designs afford better lateral impact protection.
