The amount of injured snowboarders is increasing each year. The reason is due to the success of snowboarding for teenagers. Accidents occur more during the first hours of practice. Upper limb is the first location: fore-arm breaks and wrist fractures are very common. Elbow and shoulder dislocations also occur often for snowboarders. The location of most injuries for lower leg is the ankle; we found many ankle sprains and astragalus's breaks. The knee sprain is rare unlike alpine ski. Prevention has to be developed to give a better image of this sport, in fact the attitude of the participants is the main reason for the accidents.
