RESUMO
The region Davos/Klosters is a big wintersport area in Switzerland, where more than 5 million kilometers of vertical drop are skied per year. Over the last 20 years 28,777 patients with wintersport accidents have been treated in the 100-bed hospital of Davos, 85% of these patients have sustained their accident while skiing. An analysis of these datas show an increase of ski accidents as well as an increase of the distance skied. Especially an increase in snowboard accidents is noted over the last few years with a preponderance of lesions of the upper extremity. Injuries of the head, the trunk and simple skin lacerations remain stable over that period. Injuries of the upper extremity are increasing, whereas lower extremity lesions are slightly decreasing. There is a significant decrease of fractures of the leg, while at the same time an important increase of knee injuries is noted. Young patients below 20 years and those between 31 and 40 years of age sustained less accidents over the last 20 years, while the rest of the alpine skiers remain more or less stable in their accident incidence.
