Only real thing I regret when I broke my leg was not using a cane after crutches. Didn't realize using the crutches too long led to my fibula reattaching incorrectly and breaking again a year later randomly as I was walking.
Oh wow. That's terrible. I'm sorry you went through that. I actually bought a neat cane last month at a Ren faire that I could probably put to use of my doctors and physical therapist(s) want me to. I bought the cane as a prop for costumes, but also as a stick to beat raccoons with. I got jumped by a gang of raccoons a few months ago, and the fuckers keep breaking into my ducks' outside enclosure. I take the cane out with me whenever it's dark.
I'm pretty sure that I healed with my foot in an unnatural position (outside tiles up slightly) causing the bone to heal in a shortened position. They don't do anything to your fibula in most cases as it bears very little weight, it's just allowed to heal on its own.
