Whatnobeer, how long did it take the NHS to spot you’d broken it?
Anything over 2-3 weeks and it’ll probably need a screw and graft according to what I’ve read and had happen to me.
From my experience you need to rest it completely whilst it’s in plaster and then again when it comes out. No carrying, lifting, opening jars, driving, riding in any way shape or form.
I broke mine in August 2011, was operated on in Dec 11 after it failed to heal due to them missing it initially in August before I went for more X-rays after trying to MTFU for 3 weeks thinking it was just a sprain doing carrying, riding and heavy lifting.
I and am only just riding again (albeit very very carefully). At a minimum I’d budget 12 weeks of no exercise on the bike.
Seriously, this is one bone you don’t want to rush healing due to it’s rubbish blood supply. If you can afford it, it might be worth going to see Brian Simpson for some magnetic field and laser treatments (not cheap but I think it made a difference.
