Background: National Collegiate Athletic Association (NCAA) football players are at a high risk of injuries. Elbow injuries are uncommon, but there are insufficient data specifically on elbow injuries sustained in NCAA football players. Purpose: To define the epidemiology of elbow injuries in NCAA football players during the 2009-2010 to 2013-2014 seasons using data from the NCAA Injury Surveillance Program (NCAA-ISP). Study Design: Descriptive epidemiology study. Methods: Using the NCAA-ISP database, a convenience sample of NCAA football athletes was reviewed to determine the types, rates, and trends in elbow injuries. Several factors were examined, including the diagnosis, injury setting, time lost from sport, surgical necessity, and injury recurrence. Raw injury data were obtained as well as weighted totals from the NCAA-ISP to generate national estimates and adjust for underreporting. Injury rates were calculated by dividing the number of injuries by the total number of athlete-exposures (AEs). The rate ratios of injuries during competition versus practice were compared, as were the rate ratios of preseason, regular-season, and postseason injuries by type. Results: We identified 4874 total elbow injuries from the 2009-2010 to 2013-2014 seasons. The rate of injuries overall was 1.892 per 10,000 AEs. The rate for competition was 9.053 per 10,000 AEs and 1.121 per 10,000 AEs for practice. The rate ratio between competition and practice was 8.08 (95% CI, 6.04-10.80). Injury rates for the preseason, regular season, and postseason were 1.851, 1.936, and 1.406 per 10,000 AEs, respectively. Acute elbow instability was the most common injury type (65.43%). The most common mechanism was a contact injury (86.77%); 96.82% of injuries did not require surgery, and most elbow injuries required less than 24 hours of participation restriction (67.33%). Conclusion: Although elbow injuries in NCAA football players are uncommon, it is important to recognize and treat these injuries appropriately. Dislocations and ulnar collateral ligament injuries caused athletes to miss extended periods of play. Fortunately, a majority of injuries resulted in less than 24 hours of participation restriction. Particular attention should be given to preventing elbow injuries, especially ulnar collateral ligament strains, hyperextension injuries, and acute instability.
Elbow Injuries in National Collegiate Athletic Association Athletes: A 5-Season Epidemiological Study
Background: Little research has focused on the rates and patterns of elbow injuries in National Collegiate Athletic Association (NCAA) student-athletes. Purpose: To describe the epidemiological patterns of elbow injuries in NCAA athletes during 5 seasons over the academic years 2009 through 2014 using the NCAA Injury Surveillance Program (NCAA-ISP) database. Study Design: Descriptive epidemiology study. Methods: A voluntary convenience sample of NCAA varsity teams from 11 sports was examined to determine the rates and patterns of elbow injuries. Rates and distributions of elbow injuries were identified within the context of sport, event type, time in season, mechanism, time lost from sport, surgical treatment, and injury type. Rates of injury were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). An AE was defined as any student participation in 1 NCAA-sanctioned practice or competition with an inherent risk of exposure to potential injury. Injury rate ratios (IRRs) and injury proportion ratios (IPRs) were then calculated to compare the rates within and between sports by event type, season, sex, mechanism, surgical treatment, and time lost from sport. Comparisons between sexes were made using only sports data that had both male and female samples. Results: Overall, 373 elbow injuries were reported in the NCAA-ISP data set during the 2009-2010 through 2013-2014 academic years among 11 varsity sports. The overall rate of injury was 1.76 per 10,000 AEs. The rate of elbow injuries in men was 0.74 per 10,000 AEs, while women experienced injuries at a rate of 0.63 per 10,000 AEs. In sex-comparable sports, men were 1.17 times more likely to experience an elbow injury compared with women. Men’s wrestling (6.00/10,000 AEs) and women’s tennis (1.86/10,000 AEs) were the sports with the highest rates of elbow injuries by sex, respectively. The top 3 highest injury rates overall occurred in men’s wrestling, baseball, and tennis. Elbow injuries were 3.5 times more likely to occur during competition compared with practice. Athletes were 0.76 times less likely to sustain an elbow injury during the preseason compared with in-season. Contact events were the most common mechanism of injury (67%). For sex-comparable sports, men were 2.41 times more likely than women to have contact as their injury mechanism (95% CI, 0.78-7.38). The majority of athletes missed less than 24 hours of participation time (67%), and only a minority (3%) of patients with elbow injuries went on to have surgical intervention. Elbow ulnar collateral ligament injuries were most common (26% of total injuries). Conclusion: Analysis of the study data demonstrated a significant rate of elbow injuries, 1.76 injuries per 10,000 AEs in NCAA collegiate athletes. Higher injury rates can be expected in males within sex-comparable sports. Elbow injuries are most common in the setting of competitions and most commonly occur secondary to contact-type mechanisms. Injuries were more likely to occur during in-season play. The majority of injuries required less than 24 hours of time away from sport and did not require surgical intervention.
