Lacrosse-related injuries in boys and girls treated in U.S.emergency departments,2000-2016

Background:Lacrosse is one of the fastest-growing sports in the United States.Its rules regarding permitted contact differ by sex and age.There are no known studies using a nationally representative data set to analyze lacrosse injury patterns over several years by sex and age in the youth population.Methods:A retrospective analysis was performed using data from the National Electronic Injury Surveillance System for youth aged 11-18 years who were treated for lacrosse-related injuries in U.S.emergency departments from 2000 to 2016.Based on our review of the case narratives,we created and coded a new injury-mechanism variable.We generated national estimates from 6406 cases.Results:An estimated 206,274 lacrosse-related injuries to youths aged 11-18 years were treated in U.S.emergency departments from 2000 to 2016.The rate of injuries per 10,000 significantly increased from 1.9 in 2000 to a peak of 5.3 in 2012(p<0.0001),followed by a significant decrease to 3.4 in 2016(p=0.020).Injury mechanism,body part injured,and diagnosis differed by sex.Boys were 1.62 times(95%confidence interval(95%CI):1.25-2.09)more likely than girls to be injured by player-to-player contact.Girls were 2.21 times(95%CI:1.96-2.49)more likely than boys to have non-contact injuries.Overall,as age increased,the percentage of injuries from lacrosse sticks decreased and player-toplayer contact increased.Conclusion:Despite additional protective regulations in the sport,lacrosse is an important source of injury where we continue to see differences by sex and age.This study supports the continuation,modification,and addition of rules aimed at reducing lacrosse injury risk.

Epidemiology of shoulder dislocations presenting to United States emergency departments:An updated ten-year study

BACKGROUND Glenohumeral dislocation is a common injury that may predispose patients to chronic pain and instability.However,there is a paucity of current data available regarding the epidemiological trends of this injury.AIM To provide an updated,comparative assessment of the epidemiology of shoulder dislocations presenting to emergency departments in the United States.We also sought to analyze patient demographic risk factors and consumer products associated with dislocation events.METHODS Data were obtained from the national electronic injury surveillance system database for glenohumeral dislocations between 2012 and 2021.Incidence,age,sex,and injury characteristics were analyzed using weighted population statistics as well as incidence rates and 95%confidence intervals(CI).RESULTS In total,an estimated 773039 shoulder dislocations(CI:640598-905481)presented to emergency rooms across the United States during the study period.The annual incidence rate was 23.96 per 100000 persons and the average patient age at the time of injury was 37.1 years.Significantly more male patients sustained dislocations than female patients(537189,69.5%,vs 235834,30.5%,P<0.001).With regard to associated consumer products,sports and recreation equipment were involved in the highest proportion of incidents(44.31%),followed by home structures and construction materials(21.22%),and home furnishings,fixtures,and accessories(21.21%).Regarding product sub-groups,stairs,ramps,landings,floors was cited in the greatest number of cases(131745).CONCLUSION The national annual incidence rate of glenohumeral dislocations throughout the study period was approximately 23.92 per 100000 persons.Male adolescents sustained the highest proportion of dislocations,with a peak incidence in age group 15-20 years,predominantly secondary to participation in sporting and recreational activities.Conversely,women experienced a relatively consistent incidence of dislocation throughout their lifespan.After age 63,the incidence rate of dislocations in females was found to surpass that observed in males.
