A 5 year national survey of martial arts was done using the National Electronic Injury Surveillance System (NEISS). Seventy-four percent of the injuries involved the extremities and 95% were mild to moderate in nature. Even though most of the injury types were contusions/abrasions (36%). lacerations (14%), and sprains/strains (28%), 15% were dislocations and fractures. Five percent of all injuries were severe, and there were 18 hospitalizations. There were no deaths. Weapon-related injuries were rare and never serious. Overall, the risk of serious injury in the sport was found to be low, especially when compared to other contact sports.
