Epidemiology of rugby-related fractures in high school- and college-aged players in the United States: an analysis of the 1999-2018 NEISS database.

Abstract

Rugby is a high-impact collision sport with identical competition rules by sex. The aim of this study was to analyze the trend of rugby-related fractures by body site, sex, and age in amateur athletes from 1999 to 2018. The National Electronic Injury Surveillance System (NEISS) database was queried to characterize rugby-related injuries from 1999 to 2018 in patients aged 14-23 years old. National injury estimates were calculated using sample weights. Chi-square analysis and one-way ANOVA were performed to compare categorical variables. Out of a total of 43,722 weighted cases of rugby-related fractures over the 19-year period, 70.9% were among high school- and college-aged males and females between the ages of 14-23 years (<i>N</i> = 30,996). Males constituted 79.3% of cases whereas females composed 20.7% of the cases. The proportion of upper extremity fractures was similar in both males and females, yet facial fractures were significantly more common among males than females (27.9% vs. 14.6%, <i>P</i> < 0.001). Among facial fractures, nasal fractures represented 74.4% of the sample, yet facial fractures only resulted in hospital admittance in 1.3% of cases. Lower extremity fractures were more likely to be severe, with 11.3% of LE cases being admitted to the hospital. Rugby players in the US diagnosed in the ED with fractures consisted largely of male, high school- and college-aged athletes. Males and females experienced upper and lower-extremity fractures at comparable rates, yet lower extremity injuries were more likely to be admitted to a hospital. Men were significantly more likely to experience a facial fracture in which a majority were nasal fractures.
