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.

I've still never heard a satisfactory explanation for how in the hell two parts of a bone, broken such that they aren't even touching, can find their way back to each other and heal. My son broke his collar bone, and the hospital sent him home in a sling. When I looked at the x-ray, I couldn't believe that's the correct treatment. But a month or two later and he was good as new. Absolutely blows my mind every time I think of it.
