PurposeThe participation in extreme and contact sports has grown internationally, despite the significant risk for major and multiple injuries. We conducted this multicenter study to evaluate sport-specific injury patterns and mechanisms, to characterize individuals at risk and to identify possible approaches for prevention.MethodsWe compared demographic data, severity and patterns of injuries; and the pre- and in-hospital management from an international population-based prospective trauma database (TraumaRegister DGU®). The registry was screened for sport-related injuries, and only patients with major injuries [Injury Severity Score (ISS) ≥ 9 points] related to extreme or contact sports activities were included (January 1, 2002, to December 31, 2012). Parameters were compared for different types of sports activities: (1) Airborne sports, (2) Climbing, (3) Skateboarding/Skating, (4) Contact sports. The following countries participated: Germany, Austria, Switzerland, Finland, Slovenia, Belgium, Luxembourg, and The Netherlands. Statistical analyses were performed with SPSS (Version 22, IBM Inc., Armonk, New York).ResultsA total of 278 athletes were identified within the study period and classified into four groups: Airborne sports (n = 105) were associated with the highest injury severity (ISS 22.4 ± 14.6), followed by climbing (n = 35, ISS 16.5 ± 12), skating (n = 67, ISS 15.2 ± 10.3) and contact sports (n = 71, ISS 10.4 ± 9.2). Especially high falls resulted in a significant rate of spinal injuries in airborne activities (68.6%, p < 0.001) and in climbing accidents (45.7%). Skating was associated with the highest rate of loss of consciousness (LOC) at scene (27.1%), the highest pre-hospital intubation rate (33.3%), and also the highest in-hospital mortality (15.2%, p < 0.001), related to major head injuries.ConclusionsExtreme and contact sports related major injuries predominantly affect young male athletes. Especially skaters are at risk for debilitating and lethal head injuries. Individuals recognizing sport-specific hazards might modify their risk behavior.Level Of EvidenceDescriptive Epidemiologic Study, Level II.
