The purpose of this study is to analyze patterns and trends of maxillofacial injuries in bare-knuckle fighting. Results comparisons with other combat sports are provided in the Discussion section.The study design is a retrospective cohort study. Data were collected by a single ringside physician who participated in all bouts. Predictor variables were number of rounds and final fight result (ie, knockout, technical knockout, and decision). The primary outcome variable was the frequency of maxillofacial injury, and secondary outcome variables were type of injury (laceration/fracture) and traumatic brain injury. The chi-square test was used to determine if there was any statistical significance between the predictor variables.Study sample consisted in fighters who suffered maxillofacial injuries during the matches from June 2018 to March 2022 (n = 177). A total of 177 fighters sustained maxillofacial trauma in 301 matches, and a total of 211 maxillofacial injuries were identified. Of the 211 injuries, 184 were lacerations and 27 were fractures. Proportionally more injuries occurred in matches that lasted 5 rounds (33%), and a significant association was found between the number of rounds fought and the frequency of injury (P .00001). From a total of 107 technical knockouts, 74% of them caused at least 1 injury; from 96 knockouts, 60% caused at least 1 injury; and from 89 fights that ended in decision, 83% of them caused at least 1 injury. A statistically significant association was found between final fight result and frequency of injury (P .00001). P value less than 0.05 (95% confidence interval) was considered statistically significant.Maxillofacial injuries were predominantly associated with longer fights and fights which result were knockout/technical knockout. Traumatic brain injury was associated with knockout results, which mostly occurred in the first and second rounds. |
