Time loss (TL) injuries resulted in participation restriction time of at least 24 hours. Non-time loss (NTL) injuries resulted in participation restriction time under 24 hours.Abstract: RESULTS: There were 705 TL and NTL women's lacrosse injuries, resulting inan injury rate of 4.93/1,000 athlete-exposures (AEs) (95% CI: 4.57-5.30). The TL and NTL injury rateswere 2.18/1,000 AE (95% CI: 1.93-2.42) and 2.64/1,000 AE (95% CI: 2.37-2.90), respectively. Most injuries were to the lower extremity (competition: 64.4%; practice: 71.2%). Most injuries in competition were sprains (26.0%), contusions (19.6%), and strains (19.2%); most injuries in practice were strains (21.4%), sprains (18.1%), and inflammatory conditions (15.8%). Concussions comprised the highest proportion of head/face injuries (competition: 82.1%; practice: 54.5%). No eye injuries were reported. The highest proportion of injuries were player contact (27.4%) in competitions and non-contact (32.1%) in practices. Contact with the ball and stick comprised 21.5% of competition and 14.0% of practice injuries.Abstract: CONCLUSIONS: The study is the most robust assessment of collegiate women's lacrosse injuries to date, utilizing surveillance data that includes both TL and NTL injuries. Over half of all injuries were NTL; inclusion of such injuries further highlights the breadth of injuries managed by team medical staff.
