Lindsey Vonn had surgery on a fracture of her left leg following the American's heavy fall in the Winter Olympics downhill, the hospital said in a statement given to Italian media on Sunday.
"In the afternoon, (Vonn) underwent orthopedic surgery to stabilize a fracture of the left leg," the Ca' Foncello hospital in Treviso said.
Vonn, 41, was flown to Treviso after she was strapped into a medical stretcher and winched off the sunlit Olimpia delle Tofane piste in Cortina d'Ampezzo.
Vonn, whose battle to reach the start line despite the serious injury to her left knee dominated the opening days of the Milano Cortina Olympics, saw her unlikely quest halted in screaming agony on the snow.
Wearing bib number 13 and with a brace on the left knee she injured in a crash at Crans Montana on January 30, Vonn looked pumped up at the start gate.
She tapped her ski poles before setting off in typically aggressive fashion down one of her favorite pistes on a mountain that has rewarded her in the past.
The 2010 gold medalist, the second most successful female World Cup skier of all time with 84 wins, appeared to clip the fourth gate with her shoulder, losing control and being launched into the air.
She then barreled off the course at high speed before coming to rest in a crumpled heap.
Vonn could be heard screaming on television coverage as fans and teammates gasped in horror before a shocked hush fell on the packed finish area.
She was quickly surrounded by several medics and officials before a yellow Falco 2 Alpine rescue helicopter arrived and winched her away on an orange stretcher.
