Broke mine through the neck about 4 years ago and had it reattached with 3 nice big B&Q coach bolts. After 10 months I was still suffering a lack of mobility which would have made riding pretty hard I reckon- I could go the motorbike but wasn’t cycling at the time (through choice, btw- I came back to mountain biking after the break- because of the break in fact!)
Had mine checked over just recently and apparently it’s in good nick, but it does often hurt- especially after any hard exercise, but also after long days on my feet etc, just a response to use it seems. Not to be negative but I’ve not had a pain-free day since I came off the morphine. But, it’s generally tolerable without painkillers and always managable with prescription painkillers, so that’s not too bad. Hospital has offered to open it up, have a hoover-out of scar tissue and maybe remove the bolts but there’s drawbacks to that and so far I’ve not felt it neccesary.
Probably sounds a bit negative all that. What I’d say though is that apart from the pain/discomfort and a little loss of flexibility it does everything I want a leg to do. It’s held me back in terms of making it hard to attain my current level of strength and fitness, but most people wouldn’t guess to see me riding I reckon. My cardio fitness is the problem now 😉
