Objective : The purpose of this study is to investigate the incidence and patterns of injury occurred in snowboard accident. Method : We evaluated 69 patients with snowboard injury who visited to the sports clinic in the Yong Pyong Ski Resort from Nov. 1996 to Feb. 1997. The incidence of snowboard injury was analysed. Results : The incidence of snowboard injury was 3.7% (69 cases) of total patients (1,850 cases) who visited sports clinic during 96-97 season. Among the patients, male were 58 cases (84.1%) and female were 11 (15.9%). The most common distribution of age was second decade(53.6%). The most common type of injury was fracture(42.0%). According to the data, the patients who injury in carpal area were 28.9% (20 cases) forearm 20.5% (14 cases), hand 13.1% (9 cases), upper arm 7.2% (5 cases), ankle 7.2% (5 cases), head 7.2% (5 cases), elbow 5.8% (4 cases), knee 5.8% (4 cases), hip 2.9% (2 cases), and ankle 1.4% (1 case). The moat common type of injury in upper extremities was fracture(53.9%). The most common site of injury in upper extremities was carpal area (38.4%). The most common type of injury in lower extremities was sprain. The most common site of injury in lower extremities was ankle(41.7%). The most common site of fracture was forearm (48.2%). Conclusion : The most common age for snowboard injury was second decade and this group represented 53.6% of all snowboard injury. The most common type of injury was fracture (42%) . The forearm was the most common site of fracture. Upper extremities were more involved than lower extremities. The most common type of injury in upper extremities was fracture, while in lower extremities was sprain. The most common site of injury was carpal area, and in lower extremities was ankle. We must be aware of the patterns, and prevention of the snowboard injury.
