We evaluated 1,743 patients with ski injuries who visited to the emergency room located in the Young Pyung Ski Resorts from Nov. 25, 1995 to Mar. 31, 1996. Among the patients, 971 patients were male and 772 were female. In age distribution, young patients from 21 to 30 years old were most comman. 44.8 % of ski injured patients were admitted on weekend, and 73.2% were on sun-shiny day. The most common injury mechanism was slip-down(65.5 %). Among the many prevention methods of skin injury such as physical preparation prior to the skiing season, safe equipment, correcting skiing technique, consideration for other slope users and adaptation to the snow condition, etc., this survey revealed that the avoidance of a cold start is important. Simple injuries such as abrasion, contusion and simple laceration were most common as 66.0 %, followed by ligament injuries(19.5 %). There were 4 serious Injured patients(ISS >_2 16) who were injured by colliding with either moving subject or obstatides along the ski slopes. Among 4 patients, 1 patients was severe head injury and died, 1 patien was spinal injury and pneumothorax, and 2 patients were hemoperitoneum Severe injured patients are all beginning skiers and they were injured at a slope for beginning skiers. Certainly, the result of this study would indicate that skier's experience such as total number of days skied and self-assessed ability, correlated with the risk of injury. Emergency post should be locate at the slope for beginning skiers and/or intermedlate skiers, and the medical equi ts for emergency care of shock, head injury, spinal injury and chest injury must be equipped at post.
