To clarify the characteristics of injuries occurring in snowboarding accidents, we compared, injuries in 138 snowboarders and 128 skiers (aged 15–35 years), injured at the “H” Ski Resort. In the snowboarder group, injuries to the upper extremities, particularly the wrist joint, were more frequent, whereas injuries to the lower extremities, particularly the knee joint, were less frequent. As for the type of injury, fractures were more frequent in snowboarders, while sprains and ligament injuries were less frequent. Fractures, sprains of the wrist joint, and contusions of the shoulder were more frequent in snowboarders, with sprains of the knee joint and the thumb were being less frequent. The duration of sporting activity was significantly longer in snowboarders. Injuries to snowboarders occurred more often while they were traveling at “reckless speed” on moderate slopes. There were no significant differences in skill levels between the two groups. Differences between the snow boarders' and skiers' boots and differences in sliding on boards and on skis are believed to have contributed to the differences in their injuries. Our analysis indicates that it is necessary to create slopes that are safe and enjoyable for board riders as well as skiers. Lessons are also recommended so that snowboarders learn the proper technique, and understand the general principles of slope safety; the potential for injury would thus be reduced.
