The purpose of this study was to analyze the characteristics and severity of wrist injuries in snowboarding.
December 2005 to February 2008, Snowboarders who experienced wrist injures were included in this study. On the basis of the medical records and radiographic evaluation, the severity of distal radius fracture was classified according to the Arbeitsgemeinschaft fur Osteosynthesefragen/Association for the Study of Internal Fixation (AO/ASIF) classification.
Most of the injured snowboarders were a either of the beginner (35 cases, 46.1%) or the intermediate (27 cases, 35.5%) level. The most common cause of injury in snowboarding was a slip down (60 cases, 78.9%). Comminuted and articular fractures classified as AO types A3, B, and C, which required surgical reduction, made up 42.3% of the distal radial fractures in snowboarders. When we analyzed the differences in severity between the educated and the non-educated groups, an A2 type injury in the AO classification was the most common type of injury in the educated group (20 cases, 38.5%), it means less severe fractures ocurred in the educated group (p=0.045). The most frequent injury mechanism of fractures was slip down (48 cases, 63.2%), and a slip down backwards was the dominant type of slip down (36 cases, 75.0%) (p=0.031).
Among the snowboarders in this study who suffered self-down injury to the wrist, more fractures were associated with a backwards slip down than with a forward slip down due to over extension. For educated snowboarders the severity of fracture was lower than it was for uneducated snowboarders.
