Recreational waterslide injuries.

Recreational waterslide facilities are a growing phenomenon in the United States, and injuries associated with their use are beginning to appear. Although there have been fatalities, the vast majority of injuries are minor, and occur over a large denominator of slide rides. The overall incidence of injuries is low, though the incidence varies from one facility to another. If safety practices and design features are implemented, waterslide use may become safer. Epidemiologic data will be required to clearly identify the optimal features of injury prevention.
