PEAK LOWER EXTREMITY SOCCER INJURIES OCCUR IMMEDIATELY FOLLOWING GROWTH IN ADOLESCENTS: AN EPIDEMIOLOGIC REVIEW OF EMERGENCY DEPARTMENT VISITS

BACKGROUND: Soccer has become the most popular youth sport in the world. Within the last decade, there has been limited epidemiologic research on pediatric soccer-related injuries based on sex and age. PURPOSE: To examine trends associated with soccer injuries presenting to emergency departments and to describe differences in injury pattern and location based on sex and age during periods of growth. METHODS: An epidemiologic study was conducted utilizing publicly accessible data from the National Electronic Injury Surveillance System (NEISS). The NEISS compiles Emergency Department (ED) data on all injuries presenting to the approximately 100 participating network hospitals in the United States. Information on all soccer-related injuries occurring in ages 7-19 from January 2009 – December 2018 was extracted and summary statistics were calculated. RESULTS: Approximately 54,287 pediatric soccer-related injuries were identified. The average age for all injuries was 13.3 years, and males (60.50%) presented more often than females (39.50%). Concussions and head injuries (15.57%) were most commonly reported overall, with a greater percentage occurring in females than males (17.44% vs. 14.35%). The ankle (15.3%) was the second most common injury location with females also presenting more commonly than males (18.71% vs. 13.62%). Age and sex-based evaluation noted peaks in lower extremity injuries in females younger than in males. Both ankle (F=13-15 years, M=15-17 years) and knee (F=14 years, M=16 years) injuries peaked at ages coinciding with recognized sex-based lower extremity skeletal maturity (Figure 1). CONCLUSION: Peak pediatric soccer-related ankle and knee injuries presenting to emergency departments occur at different ages in females and males and appear to, on average, coincide with maturation (age 14 in females and 16 in males). Lower extremity injuries significantly increase nearing the completion of lower extremity growth, and may indicate appropriate timing for differential sex-specific injury prevention programs within soccer.
