Self-Report Ski Slash Survey

Recently during ski racing competitions, a few high-profile ski accidents have resulted in severe life-threatening laceration injuries. Ski-laceration injuries can range from fatal leg gashes to a few stitches. Lacerations are caused by ski edges cutting through skin, muscles, and arteries during falls of varying severity. Most alarming, these laceration injuries are occurring during adolescent and young adult ski races.
These high-profile laceration injuries have raised awareness about the risks during skiing, and there is a desire by the skiing community to better protect skiers during recreation, practice, and competition. Identifying and describing injury rates and severity for a specific group of athletes is the foundation of injury prevention research. Unfortunately, ski injury research is conducted for top-level athletes or recreational skiers to observe general injury trends and does not typically focus on laceration injuries of US adolescents and young adults.
The Self-Report Slash Injury Survey (Slash Survey) was conducted to (a) measure the frequency, severity, and body location of laceration injuries during skiing and (b) identify the skiing environment and ski maintenance level during laceration injuries. The Slash Survey will be conducted annually to establish detailed information about ski laceration injuries among adolescent and young adult US ski racers for the development of mitigation strategies.
The 2018-2019 Slash Survey was an online survey that asked participants ages 10-24, who are enrolled in US ski race programs, to report whether they experienced a laceration injury and what ski maintenance was used during the 2018-2019 ski season. The Slash Survey results suggest that the laceration injury rate during the 2018-2019 ski season was 6.8% and almost half were slight (i.e. less than 1 day of absence from the sport). For respondents of the survey, no correlation was found between laceration injuries and (a) slope surface conditions, (b) outside temperature, (c) weather, (d) skiing activity, and (e) ski maintenance (tuning). For all respondents, the most common ski tuning method was using a file guide by hand (29%), automated ski tune at a ski shop (20%), stone grind (17%), and cup wheel grinder (17%). Furthermore, open-ended responses suggest that a ski community narrative may be amplifying the awareness of laceration injuries. Full paper published here: https://ouci.dntb.gov.ua/en/works/7qvx3VK4/
