Winter sport musculoskeletal injuries: epidemiology and factors predicting hospital admission.

introductionParticipation in winter sports such as skiing, snowboarding and snowmobiling is associated with risk of musculoskeletal injury. The purpose of our study was to describe and quantify emergency department encounters associated with these sports.

methodsThe National Electronic Injury Surveillance System (NEISS) was queried for skiing-, snowboarding- and snowmobiling-related injuries from 2009 to 2018. Patient demographics and disposition data were collected from emergency department encounters. Descriptive statistics were utilized to describe the trends in injuries from each sport and factors associated with the sports-specific injuries.

resultsFrom 2009 to 2018, there were an estimated 156,353 injuries related to snowboarding, skiing, or snowmobiling. Estimated injury incidence per 100,000 people decreased over time for skiing (3.24-1.23), snowboarding (3.98-1.22,) and snowmobiling (0.71-0.22,). The most common injury location by sport was shoulder for skiing (29.6%), wrist for snowboarding (32.5%) and shoulder for snowmobiling (21.9%), with fractures being the most common diagnosis. Only 4.5% required admission to the hospital. Fracture or dislocation was associated with highest likelihood of hospital admission (OR 42.34; 95% CI 22.59-79.37). Snowmobiling injuries (OR 1.63; 95% CI 1.20-2.22) and white race (OR 1.42; 95% CI 1.17-1.72) were also both associated with increased risk of hospital admission.

conclusionsUpper extremity injuries, particularly those involving fractures, were more common than lower extremity injuries for all three sports, with the shoulder being the most common location of injury for skiing and snowmobiling. This study can serve as the foundation for future research in sports safety and health policy to continue the declining trend of musculoskeletal injuries in the future. LEVEL OF EVIDENCE: III.
