I've had a broken collarbone for the past 11yrs (Non-union fracture) the Consultant said it was a bit too close to the end to plate and would leave it dangerously weak if I fell on it again (mind you it was the 4th time I'd broken this one)
It depends where the break is as to whether surgery is the best option.
This is the x-ray at 7 weeks, the 13 week one is near identical:
unfortunately I've not managed to get a copy of the original x-ray on the night of the off as that one shows a pretty clean and close break., for some reason its shown to me and very quickly closed!
I ended up upside down with the bike on top of me but all in one piece thankfully, when I eventually managed to disentangle the bike and stand up I realised the ditch was over 7ft deep (I'm only 5' 11"), lucky again as it was dry but still took ages to climb out and rescue the bike as well
