Two Minutes for Roughing: A National Analysis of Ice Hockey Injuries from American Trauma Centers

Abstract

Background Hockey is a high-impact sport that carries a risk of injury. No national-level studies defining the burden of injury in this sport have yet been performed. This study sought to analyze patient demographics, injury types and severity, and outcomes after trauma sustained while playing hockey. Methods Retrospective analysis of hockey-related injuries was performed using the National Trauma Data Bank (NTDB) (2007-2018). Patients were identified based on ICD-9 and -10 codes without exclusions. Demographics, clinical/injury data, and outcomes were examined using univariate analysis. Subgroup analysis was performed by patient sex. Results Hockey injuries (n = 306) comprised <1% of the NTDB. Median age was 15 years [IQR 13-25] (range 5-71). Most patients (n = 279, 91%) were male. Lower extremities were the most frequently injured body region (n = 88, 29%). Head injuries occurred in 19% (n = 57). Facial injuries occurred in 6% (n = 17). Tooth loss was infrequent (n = 2, 1%). One (<1%) death occurred after a hockey-related brain injury. Clinical/injury data between male and female hockey players were comparable apart from a significantly higher rate of upper extremity fractures among the female cohort (22% vs 4%, P < .001). Conclusion Perceptions that hockey players may frequently sustain head, face, and tooth injuries from collisions, fighting, or stick/puck impacts were not supported by this national-level study, in which lower extremity fractures were the most common injury. While hockey injury prevention equipment has primarily focused on head/face protection (eg, helmets and mouthguards), this analysis suggests increased focus on extremity protective measures is warranted.
