A retrospective analysis of ski injuries at a large Utah ski area was conducted to identify injury trends and to corroborate information from previous comparable studies. A total of 5360 injuries were treated at the ski area base clinic between 1989 and 1993. The overall injury rate was approximately 2.1 per 1000 skier visits. Knee injuries were the most prevelant injury type, accounting for 43% of all injuries. Significant differences with previously published literature were noted in mean and median age of injured skiers, indicating demographic differences among the injured population at ski areas. Distributional analyses of injury diagnosis broken down by sex revealed significant differences between ski area injury rates and types both overall and between men and women, and demonstrate the need for multiarea studies aimed at identifying trends associated with terrain, snow conditions, and skier demographics. A prospective study begun in 1991 will attempt to quantify the significant differences between male and female skiing injuries at this ski area and will expand to several areas in close proximity for further study.
