Musculoskeletal Injuries in National Hockey League Goaltenders.

BACKGROUND Hockey goaltenders are exposed to unique in-game physical demands, different from those experienced by other positional players. While previous studies have identified the injuries experienced by elite goaltenders, these have been limited by the use of secondary data or data from small samples over relatively short time intervals. PURPOSE To quantify the type and number of injuries occurring in National Hockey League (NHL) goaltenders and the time lost due to these injuries. STUDY DESIGN Descriptive epidemiology study. METHODS Data from the NHL's Athlete Health Management System was analyzed between the 2009-2010 and 2022-2023 seasons. The total number of each musculoskeletal injury, the total days missed (TDM) (a surrogate measure for injury severity), and the exposure-adjusted injury rate (EAIR) was quantified. For each individual diagnosis, the total number of injuries, mean, median, standard deviation, and minimum and maximum (range) TDM were calculated. RESULTS There were 1585 musculoskeletal injuries recorded over 14 NHL seasons resulting in 31,406 TDM. The number of total injuries per year was stable across the data collection period. The EAIR was higher in the preseason (69.4) and postseason (46.8) compared with the regular season (17.1). The majority of the injuries occurred during games (n = 904), followed by practice and off-ice activities (n = 681). The most common mechanisms were noncontact (n = 673), incidental contact (n = 252), and "unknown/other" (n = 374). Proximal adductor injuries accounted for the largest number of injuries (n = 371), leading to the highest total TDM (n = 6126). Concussions (n = 110) and MCL sprains (n = 95) were the second and third most common injuries, respectively. CONCLUSION The most common injuries to NHL goaltenders are proximal adductor injuries, concussions, and MCL sprains. Attention should be paid to the significant number of injuries occurring in the preseason and practice periods.
