Forensic investigation into head trauma in combat sports, blunt force homicides, and traditional martial arts

Background: The analysis of circumstantial elements in post-mortem examinations is crucial for identifying perpetrators in unarmed close-range homicides. This study explores the forensic analysis of head trauma fatalities related to combat sports, blunt force trauma homicides, and traditional martial arts (TMA), aiming to bridge the gap between historical martial arts documentation and modern forensic pathology.

Materials and methods: Following PRISMA guidelines, we conducted a systematic literature review and interdisciplinary analysis combining traditional forensic methods with the study of TMA manuscripts and consultations with martial arts experts.

Results: The research uncovered a high incidence of head injuries in combat sports and identified distinct injury patterns in blunt-force trauma homicides. In martial arts, lethal techniques targeting the cranial region were pinpointed. An algorithm was developed to differentiate between injuries from various sources effectively.

Conclusion: This study offers a framework to distinguish injuries from combat sports, homicides, and martial arts, improving diagnostic accuracy in forensic pathology. It advocates for a detailed protocol that considers the technical aspects of TMA and their forensic implications, enhancing the evaluation of head trauma cases in forensic investigations.
