Vonn shared in an Instagram post on Monday that her injuries went far beyond the complex tibia fracture in the leg she initially revealed after clipping a gate and sailing off course just 13 seconds into her run on February 8. The 41-year-old Vonn said the trauma from the crash led to compartment syndrome in the leg. Compartment syndrome involves excessive pressure building up inside a muscle, either from bleeding or swelling. High pressure restricts blood flow and can lead to permanent injury if not treated quickly. “When you have so much trauma to one area of your body so that there’s too much blood and it gets stuck and it basically crushes everything,” Vonn said. Vonn credited Dr. Tom Hackett, an orthopedic surgeon who works for Vonn and Team USA, for conducting a fasciotomy to salvage her leg.
