Snowboarding-related injuries have been associated with specific snowboarding skill levels, but differences in specific skill level have not been identified.
Injury patterns are different among skill levels.
Descriptive epidemiology study.
The subjects were 19 539 snowboarders from the Oku-Mino region in Gifu Prefecture, Japan, who were admitted to our hospital during the 12 snowboarding seasons from 1996 to 2008. They were asked to complete a questionnaire regarding age, gender, self-estimated skill level, injury location, injury type, mechanism of injury, and protective gear. Physicians documented diagnostic variables and injury severity score; these variables were compared among the self-estimated skill levels.
Of the total 19 539 injured snowboarders, 1204 (6.2%) were novices, 6409 (32.8%) were beginners, 9260 (47.4%) were intermediates, 1918 (9.8%) were experts, and the skill level was not known in 748 (3.8%). Proportions of the trunk and multiple injuries increased with increases in skill level; however, the number of head/face injuries decreased with increase in skill level. Upper extremity injuries also decreased with increase in skill level, except in novices. Dislocations and multiple injuries increased with increase in skill level, while lacerations/contusions, fractures, and bruises decreased. The mean overall injury severity score was 3.28 + or - 0.02, and the value increased significantly with increase in skill level. The proportion of collision and isolated fall injuries significantly decreased with increase in skill level, but that of jump injuries significantly increased. The percentage of protective gear use increased with the increase in skill level.
Prevalence of injury type, injury location, mechanism of injury, and percentage of protective gear use varied according to skill level, and the severity of the injury increased with increase in skill level. On the basis of our observations, we believe that snowboarding injury prevention strategies should be formulated according to skill level.
单板滑雪相关损伤与特定的单板滑雪技能水平有关，但不同技能水平之间的差异尚未确定。
损伤模式在不同技能水平之间存在差异。
描述性流行病学研究。
研究对象为日本岐阜县大野美浓地区 1996 年至 2008 年 12 个单板滑雪季节期间因伤入院的 19539 名滑雪者。他们被要求完成一份关于年龄、性别、自我评估技能水平、受伤部位、损伤类型、损伤机制和防护装备的问卷。医生记录诊断变量和损伤严重程度评分；比较了自我评估技能水平之间的这些变量。
在总共 19539 名受伤的单板滑雪者中，1204 名（6.2%）为新手，6409 名（32.8%）为初学者，9260 名（47.4%）为中级，1918 名（9.8%）为专家，748 名（3.8%）不知道自己的技能水平。随着技能水平的提高，躯干和多处损伤的比例增加，而头部/面部损伤的数量则减少。随着技能水平的提高，上肢损伤也减少，但新手除外。随着技能水平的提高，脱位和多处损伤增加，而撕裂伤/挫伤、骨折和瘀伤减少。总的损伤严重程度评分为 3.28±0.02，随着技能水平的提高，该评分显著增加。碰撞和单独跌倒损伤的比例随着技能水平的提高而显著降低，而跳跃损伤的比例则显著增加。护具使用率随着技能水平的提高而增加。
根据技能水平的不同，损伤类型、受伤部位、损伤机制和护具使用率的比例也有所不同，且损伤严重程度随技能水平的提高而增加。根据我们的观察，我们认为应根据技能水平制定单板滑雪损伤预防策略。
