In reply to gazfellows:
It depends on the break, and especially the soft tissue damage. I broke my left ankle boulder hopping at Portland a few years back. Seven screws and a plate, two ops. A year later I was still unable to run, with perhaps 40% range of motion loss, and healing process tapered off.
I was advised by a fellow who'd had a very similar fracture coming off his MC to have all the metal work taken out, which I did. My surgeon fully agreed that this could kick-start the healing process, and also be safer if you have a life style meaning you're at risk from breaking it again. A couple of months after that I was basically back to normal, albeit still requiring a bit of limbering up first thing in the morning.
Prepare for a long rehab, would be my advice. Funnily enough, even when it was bad, it didn't seem to affect my climbing that much, but running was impossible.
