Abstract

During the last seven skiing seasons, 57 patients were treated surgically for head injuries caused by skiing accidents. A typical type of injury was observed, namely the depressed fracture in 84 of the cases, accompanied by brain contusions or hematomas. The mechanism of the accidents was analyzed. A depressed fracture is caused by direct local force application, often as the result of high or not properly adjusted speed. Through this impressive observa tion of depressed fracture with or without brain damage, experimental impact mechanisms of human skull depressed fractures were studied. In the present study, a tolerance threshold of about 1 to 2 kN (can be compared to an impact of about 16 km/h) was observed for a depressed fracture in the temporal region, which often is the area of severe damage in skiing. From these analyses, it can be shown that the wearing of helmets is in fact an effective possibility for the prevention of head accidents in skiing. It should be recommended particularly for children and young people. Verf.-Referat
