No, actually the key word there was 'if'. The surgeon explained that the bone fragments would fill with something, either calcium and knit together, or soft tissue and prevent them from knitting.... ever. At which point he could go back in, enlarge the original graft site and try it again. I noted that word 'try' also and asked outright: is there any way to guarantee a successful result and he basically said no.
Now as Jimmy probably knows, or will find out soon enough, that is the bone that attaches the thumb to the hand and we motorcyclists really, really need that 1) to work 2) to be relatively pain- free and 3) need it to be pretty robust, meaning 'as new' or a well healed bone. We need that paw for the clutch.
I am concerned enough about mine that I have been looking for auto- clutch bikes; did not find any new models other than the already known Fudger A (no longer imported into the US, and used ones are rare) and the Honda 1200F, and there are not many of those around either. Not sure if they still make them and even more unsure that they make the auto clutch model.
And BTW Jimmy, do not get too worked up if they prescribe a 'bone stimulator', it is not what you might be hoping for and there is no evidence (really, none) that they work anyway.

And you probably keyed on the 4-6 months part, my thoughts would have been "What do you mean by IF it heals?"
