i broke mine in a similar stylee last year, it was plated together. Cast came off after 2 weeks as obviously the fracture was stabilised, but i had a velcro splint for a few weeks, it felt VERY weak and vunerable without the splint. But I had to force myself to wean myself off it to get strength back. There is no way I could have done anything as physical as golf within a few weeks…I broke mine at the beginning of May, didn't ride until end of August I think.
Sorry! But…do all the physio you can, get it in hot water and bend the bugger as much as possible, I'm rubbish with pain but I wish I'd pushed more cos 14 months down the line I'm still not back to anywhere near 100% mobility. Day to day is fine, but I doubt it'll ever be fully right though.
Good luck!
