Mixed martial arts (MMA) is a fast-growing combat sport. There are limited studies investigating MMA's injury incidence. However, from the data available, closed head injuries and lacerations commonly are experienced by competitors. Sanctioned events require the presence of ringside physicians, who should be well versed in handling these types of injuries. Additionally, sports-medicine providers should have an appropriately equipped medical bag, and before providing coverage, they need to coordinate with emergency medical personnel in order to more efficiently deliver care if urgent situations arise. More research is needed on injury incidence and prevention in MAA.
