Rodeo related large animal injury: is protective head-gear warranted?

To compare rodeo associated large animal injuries to large animal associated trauma from other aetiologies in order to determine whether mandatory protective head-gear during rodeo is warranted. Retrospective analysis related to injury involving large animal admissions between 1 January 1990 and 31 December 1995. The setting is at the University of New Mexico Health Science Center, a level 1 trauma centre. All patients admitted with Injury Severity Scores of 1 or higher following large animal associated injuries. There were 140 admissions for which mechanism of injury was known. Thirty-nine occurred during rodeo competition and 101 occurred during other activities. Bovine associated activities were the aetiology in 34 (87%) of rodeo related injuries while equine related activities were the aetiology in 97 (96%) of non-rodeo related injuries (P<0.001). Rodeo related injuries involved the head and neck in five patients (13%) compared to 42 patients (42%) in non-rodeo activities (P=0.001). Mean Regional Injury Severity Score head and neck was 0.4 for injured rodeo riders and 1.5 for injured non-rodeo riders (P<0.001). Mean admission Glascow Coma Scale was 14.9 for rodeo-injured patients and 13.3 for non-rodeo-injured patients (P<0.001). Total ISS was significantly lower for rodeo injured patients (9.1 vs. 11.7, P=0.03). No rodeo injured patient died as a result of head injury. Mechanism of injury, ISS head, GCS, total ISS, and outcome differ between rodeo and non-rodeo injuries. While routine helmet use during non-rodeo events appears justified, mandatory use of helmets in rodeo events is unwarranted. Orthotics to protect the chest and abdomen are more likely to reduce morbidity and mortality for rodeo participants.

Head, face, and neck trauma from large animal injury in New Mexico.

BACKGROUND: Head, face, and neck injuries (HFNI) occur during animal-related trauma. We compared patients with HFNI and without HFNI after animal-related injuries to determine the significance of these injuries. METHODS: Retrospective review of admissions for animal injuries between January 1, 1990, and December 31, 1995, by age, gender, mechanism, animal, Glasgow Coma Scale (GCS) score, Injury Severity Score (ISS), Abbreviated Injury Severity score for head and neck (AIS Head/Neck), AIS score for face (AIS Face), intensive care unit stay, hospitalization length, morbidity, and mortality. RESULTS: There were 153 admissions: 61 HFNI and 92 no HFNI. Significant differences occurred in gender, animal, activity, GCS, and ISS. HFNI had higher AIS Head/Neck, AIS Face, and mortality. HFNI were from horses in 87% and occurred during recreation in 89%; 39% of patients with HFNI were 18 years or younger. CONCLUSION: HFNI occur in females and young people and produce lower GCS score, higher ISS, higher AIS Head/Neck, higher AIS Face, and higher mortality. Most occur during recreational horseback riding. Protective headgear should be mandated.
