BACKGROUND
Body checking is a common cause of youth ice hockey injuries. Consequently, USA Hockey raised the minimum age at which body checking is permitted from the Pee Wee level (11-12 years old) to the Bantam level (13-14 years old) in 2011.
PURPOSE/HYPOTHESIS: The purpose of this investigation was to determine the impact of body checking on the distribution of injuries reported in youth ice hockey players. We hypothesized that the elimination of body checking at the Pee Wee level would lower the frequency of serious injuries, particularly concussions.
STUDY DESIGN
Descriptive epidemiology study.
METHODS
Injury data from the National Electronic Injury Surveillance System (NEISS), a United States Consumer Product Safety Commission database, were analyzed for Pee Wee and Bantam players between January 1, 2008 and December 31, 2010 and again between January 1, 2013 and December 31, 2015. Data on the location of injury, diagnosis, and mechanism of injury were collected. The location of injury was categorized into 4 groups: head and neck, upper extremity, lower extremity, and core. Diagnoses investigated included concussions, fractures, lacerations, strains or sprains, internal organ injuries, and other. The mechanism of injury was broken down into 2 categories: checking and other.
RESULTS
Between the 2008-2010 and 2013-2015 seasons, overall injuries decreased by 16.6% among Pee Wee players, with injuries caused by body checking decreasing by 38.2% ( = .012). There was a significant change in the distribution of diagnoses in the Pee Wee age group during this time frame ( = .007): strains or sprains, internal organ injuries, and fractures decreased in frequency, while the number of concussions increased by 50.0%. In the Bantam age group, recorded injuries decreased by 6.8%, and there was no change in the distribution of the location of injury, diagnosis, or mechanism of injury ( > .05).
CONCLUSION
There was an observed reduction in the total number, mechanism, and type of injuries when body checking was eliminated from the Pee Wee level. There was, however, an unexpected increase in the number of concussions.
背景
身体冲撞是青少年冰球运动受伤的常见原因。因此，美国曲棍球协会于2011年将允许身体冲撞的最低年龄从少年冰球联赛水平（11 - 12岁）提高到小球员冰球联赛水平（13 - 14岁）。
目的/假设：本研究的目的是确定身体冲撞对青少年冰球运动员报告的损伤分布的影响。我们假设在少年冰球联赛水平取消身体冲撞会降低重伤频率，尤其是脑震荡。
研究设计
描述性流行病学研究。
方法
分析美国消费品安全委员会数据库国家电子伤害监测系统（NEISS）中2008年1月1日至2010年12月31日以及2013年1月1日至2015年12月31日期间少年冰球联赛和小球员冰球联赛球员的伤害数据。收集损伤部位、诊断和损伤机制的数据。损伤部位分为4组：头颈部、上肢、下肢和躯干。调查的诊断包括脑震荡、骨折、撕裂伤、拉伤或扭伤、内脏损伤及其他。损伤机制分为2类：身体冲撞和其他。
结果
在2008 - 2010赛季和2013 - 2015赛季之间，少年冰球联赛球员的总体损伤减少了16.6%，因身体冲撞导致的损伤减少了38.2%（P = 0.012）。在此期间，少年冰球联赛年龄组的诊断分布有显著变化（P = 0.007）：拉伤或扭伤、内脏损伤和骨折的频率降低，而脑震荡的数量增加了50.0%。在小球员冰球联赛年龄组，记录的损伤减少了6.8%，损伤部位、诊断或损伤机制的分布没有变化（P > 0.05）。
结论
当在少年冰球联赛水平取消身体冲撞时，观察到损伤的总数、机制和类型有所减少。然而，脑震荡的数量意外增加。
