Background: Track & field has more participants compared to any other high school sport and continues to gain popularity among middle school aged kids. Among many events, hurdles is unique because there is continued running with repeated jumping over an apparatus. Although serious injury has been anecdotally reported, there are few studies describing pediatric hurdle injuries including sex and age differences. Purpose: To investigate hurdle-related injury types and body locations based on age and sex among children and adolescents. Methods: Hurdle related injury data was extracted from the National Electronic Injury Surveillance System (NEISS), which represents emergency room visits. The search period was a 10-years (2008-2017). The eligibility criteria was < 18 years of age. Injuries were then classified based upon injury type and body location(s) involved. A chi-square (x2) analysis was employed to assess proportional differences of top three hurdle related injury types and body locations by age (<14 years vs. >15 years) and sex (male vs. female). Statistical significance was set as p<0.05. Results: A total of 749 cases related to hurdle injuries were extracted. Among recorded 749 injuries, traumatic fractures (N=218, 29.1%), joint sprain (N=191, 25.5%), and contusion/hematoma/bruise (N=78, 10.4%) were found as the top three most commonly sustained injuries. Chi-square (x2)analysis found more traumatic fractures in <14 years (34.1%) compared to >15 years (21.5%, p=0.001) while more joint sprain was identified in >15 years (29.6%) than <14 years (22.8%, p=0.036). Regarding sex comparisons, males had more traumatic fractures (35.1%) than females (24.3%, p=0.001). Conversely, females sustained more joint sprains (29.1%) and contusion/hematoma/bruise (12.7%) than males (joint sprain, 21.0%, p=0.012; contusion/hematoma/bruise, 7.5%, p=0.020). The top 3 injured body locations were ankle (N=140, 18.7%), knee (N=120, 16.0%), and wrist (N=69, 9.2%). No differences were found between body locations and age; however, statistical differences were detected by sex comparisons. Ankle injury was more common in females (24.0%) than males (12.0%, p=0.001). Yet, injury at wrist was more prevalent in males (11.7%) compared to females (7.2%, p=0.034). Conclusion: Findings of this study suggest that hurdle injury types seen in the emergency room differ by sex and age: more fractures are seen in males and younger pediatric populations while more sprains are seen in females and older adolescents. These findings may be helpful in event planning and may also play a role in injury prevention.

Objectives: The Ice Hockey Summit III provided updated scientific evidence on concussions in hockey to inform these 5 objectives: (1) describe sport related concussion (SRC) epidemiology; (2) classify prevention strategies; (3) define objective, diagnostic tests; (4) identify treatment; and (5) integrate science and clinical care into prioritized action plans and policy. Methods: Our action plan evolved from 40 scientific presentations. The 155 attendees (physicians, athletic trainers, physical therapists, nurses, neuropsychologists, scientists, engineers, coaches, and officials) voted to prioritize these action items in the final Summit session. Results: To (1) establish a national and international hockey database for SRCs at all levels; (2) eliminate body checking in Bantam youth hockey games; (3) expand a behavior modification program (Fair Play) to all youth hockey levels; (4) enforce game ejection penalties for fighting in Junior A and professional hockey leagues; (5) establish objective tests to diagnose concussion at point of care; and (6) mandate baseline testing to improve concussion diagnosis for all age groups. Conclusions: Expedient implementation of the Summit III prioritized action items is necessary to reduce the risk, severity, and consequences of concussion in the sport of ice hockey.
