Athletes at the Winter Olympics make high-flying, death-defying moves look effortless. But with little margin for error, the jumps and spins they're performing are often at least as risky as they appear.
Several athletes have already sustained injuries at the 2022 Winter Olympics in Beijing: Alpine skier Nina O’Brien broke her leg, hockey player Brianna Decker was stretchered off the ice and speed skater Park Jang-hyuk injured his hand.
According to a study by the International Olympic Committee, about 12% of almost 3,000 athletes participating in the 2018 Winter Games in PyeongChang sustained at least one injury.
Injuries in the Winter Olympics are not uncommon, but which events carry the highest risk?
Ski halfpipe was found to be the most dangerous, with 28% of athletes injured in 2018, according to the IOC study. Snowboard cross was the second-most dangerous, with 26% of athletes injured.
Ski cross came next at 25%, with snowboard slopestyle at 21% and freestyle skiing aerials at 20%.
Most of those injuries came from falls and crashes after aerial maneuvers. The most common severe injuries were fractures, as well as ligament ruptures and sprains.
