After an eventful crash in the slalom event, Nina O’Brien fractured her leg. She returned to the U.S. for treatment after receiving immediate hospital care in China. The tibia was damaged, allowing fractures to occur on her leg. At first, O’Brien observed the hill and thought it was prepared perfectly. As she led near to the end of the race, O’Brien lost her balance and tumbled in the snow. Shocked, multiple skiers came running to O’Brien to get her on the stretcher.
