Stu,
I did my right clavicle in back in 2005 (I think) and doing the same thing – admiring the view and not concentrating on where I was going. I didn’t have the op (was advised there was a strong chance of infection – which I was glad to hear cos I’m a chicken) and I was back on the bike in around six weeks, albeit gingerly.
I could show you a pick of my collarbone now, though a pick wont do it justice, but it looks absolutely appalling! Worst ‘step’ you could imagine.
In hindsight I wish Id’ve MTFU and had the op, but you cant go back and to be fair I’m fine with it (it just looks sh1t).
If as you say youre still no nearer mending than the day it happened you seriously need to chase it up.
Good luck!
