I know it's not a femur, but in May of 06' I was hit by a motorcycle while I was standing on the side of the road and compound fractured my tibia and fibula. My leg was hanging on by the skin. The doctors said I wouldn't be able to snowboard that winter and I was devastated. But in November of that year I was cleared to snowboard and went to Colorado. Just keep you're head up man...it's more than possible!
