I highly doubt that this can be corrected. Bones like the ones in the fingers can't really be thinned, can they? Wouldn't the surgeon reach the marrow? I mean, those bones are hollow, right?
They could be shortened, but that would be an enormous workload. They'd need to break every one of each finger's 3 bones and remove portions to retain proportions. That's not even considering the very delicate environment that fingers are compared to femurs, on which shortening surgeries are occasionally performed.
I'd forget it if I were you. Even -if- a surgeon does this, which I doubt, it would probably be very risky (loss of sensation or mobility, fragilised bones, circulation problems...) and it would require you to have your whole hands in casts for an extended period. And even if you did do it, a typical man's hand is large but relatively short. That's just the direction towards which you'd be headed if you got your fingers shortened.
As for the rest of the hand, it's even worse. Do you know how many bones there are in there?
I think your only - distant, impractical and improbable - hope would be to have both hands grafted, a surgery that they are starting to do on people who have lost them. It's still very rare, and the example I saw on TV was doing a lot of re-education, and still couldn't write with his hand, which, by the way, definitely looked "glued on". Not something to look forward to in your case.
So, uhm... I really think there's nothing to do about your hands, sadly. On the bright side, if you have acromegaly, it's "normal" for you, even as a female, to have huge hands, isn't it? I mean, females with that condition have them, too, right?
