I trashed into a tree Snowboarding in 2002. I shattered my femur, broke both wrists and a few ribs. I was happy to be alive so no complaints.
I got emergency surgery and a rod was placed inside my feumr. Because it was shattered (an inch or so missing) I couldn't bear weight for 6 weeks, I just hopped a lot.
I was told I wouldn't walk without a limp, would never run again and skydiving was out of the question.
I think they tell you that stuff to make you mad and work hard against them. I was walking in 6 weeks and crossed the Grand Canyon in 12 hours within 5 months. Running ain't what it used to be but I can still get the miles in. I was snowboarding again next season.
The theory about not jumping was that I *could* bend the rod and might need amputation. Well I figure anything that's going to bend that rod is going to do some other damage so I took up jumping again last year.
Best advice is work hard at rehab but DON'T get excited and come back too fast, you will injure yourself. That being said everyone comes back to quick and relapses.
Good luck. I always enjoyed http://www.mybrokenleg.com/
