Five hundred and sixty-two injured bicyclists (10.3% of all trauma patients) were registered at the Department of Oral and Maxillofacial Surgery, University of Innsbruck, Austria, between 1991 and 1996, accounting for 31% of all sports-related accidents and 48.4% of all traffic accidents. A review of the patient records revealed more severe injury profiles in sixty mountainbikers, with 55% facial bone fractures, 22% dentoalveolar trauma and 23% soft tissue injuries, compared to 502 street cyclists showing 50.8% dentoalveolar trauma, 34.5% facial bone fractures and 14% soft tissue lesions. The dominant fracture site in bicyclists was the zygoma (30.8%), whereas mountainbikers sustained an impressive 15.2% LeFort I, II and III fractures. Condyle fractures were more common in bicyclists, with 18.8% compared to 10.8% in mountainbikers. Reduction of facial injuries due to cycling-related accidents needs appropriate design of helmets with faceguards and compulsory helmet use for all cyclists, and particularly mountainbikers.
