Tibia is the big one, Fibula is the smaller one...I had a double compound fracture of both- Tib came out above the ankle,Fib below the knee. I’m sporting a 16 inch titanium rod, 2 plates and 8 screws. 6 months to recover, had to learn to walk again. Therapy 3X per week, 2+ hours-I had 0 range of motion in my ankle. Hope your recovery is quicker, easier...I had an awesome sports medicine orthopedic surgeon- would suggest getting surgery/treatment options. Mine would have healed without all the hardware, but a much longer recovery time. My accident was in 2008, not a skiing or racing incident.
Best wishes for a quick recovery...
