Have you considered a recumbent bike? I know it's not the answer you want to hear, but it would certainly take the pressure off your wrists, at least as you are regaining 100% function if you have the surgery. It might be a back-up bike for you after that. Just something to think about if you haven't.
I do empathize as I have recurring/chronic pain from a pelvic fracture in 2005. I've logged many pain-free miles since then, but just as many with aching pain. It's been a long process of determining what triggers the pain and how to best avoid it through bike selection and set up (more upright is better) and ride selection (too many hills in one ride has a tendency to trigger the pain). I hope your pain will be a thing of the past soon, but it's good to have alternatives just in case.
Good luck!
