Broken legs and ankles heal better if you walk on them within weeks

The pathology for broken collar bones was changing right as I took up mountain biking, and subsequently shattered my collarbone.

It was hotly debated at the hospital, if my specific case should be operated on or not. Each time I had a checkup, one doctor would say "wait and see" while the other was saying "I can't believe we didn't operate on this".

At any rate, the outcome was as good as if they had operated on it, according to the doc anyway. Nice of them to test it out on me!

More related to this though, I have broken both my collarbones, the first time I had little direction and just held my arm still for 2-3 months. It took forever to heal, and my arm atrophied significantly. The second time, similar severity. I was guided through rehab and I was back using my arm within the first month, very little atrophy.

Apropos of nothing in particular, when I first started mountain biking, a guy I was riding with told me: "You can divide all mountain bikers into two groups: the ones who have broken their collarbone, and the ones who are about to break their collarbone."

Knock on wood, 20 years later I still haven't broken a collarbone, but I've had plenty of scrapes, bruises, cuts, etc, a couple of concussions, a torn rotator cuff, and quite probably a broken neck (never went to the doctor to have it diagnosed, but I landed on my head hard enough to crack my helmet and knock me unconscious for a few minutes and my neck hurt for like 6 months afterwards).

Still, wouldn't trade it for anything in the world. Nothing like being out in the woods, on a bike.

Is there padding or gear sold that can reduce the likelihood?
