I had been suffering with CT for about 8 years, with the last 2 years sleeping in the splints and waking up with that sharp pain--even tried the cortisone shots (not terribly helpful).
I spoke to a couple of doctors, as one of my friends had the surgery done on just one hand and was dealing with swelling and lots of pain afterwards--I was not interested in doing that.
I found one that I really liked, and that had been recommended to me by several doctors. He suggested that I get BOTH wrists done at the same time. I used ONLY a local on each wrist (which was the most unpleasant part of the whole experience) and was awake through the whole procedure.
He did NOT put me in casts or splints. I was in bandages for 3 days, which was replaced by a bandaid over the incision/stitches. Before I left the hospital, I made sure that I could make a fist (which a little help from my other hand), and really worked hard on my range of motion for a few days. I iced my hands a lot for the first few days, which I think really helped prevent any swelling.
It's exactly one week after my surgery and I feel great. The CT pain is gone (was almost immediately). My wrists still ache some from where the incision was. I have full range of mobility (have started to play the piano again, albeit gingerly). What I can't do right now is: open water bottle, jars or pill bottles, lift anything heavier than a gallon of milk. My strength is coming back very quickly and improves each day.
I think the success of this procedure is based on 2 things: 1) your doctor, and his/her willingness to put you on a path to speedy recovery and 2) your state of mind. Being aggressive with the recovery (not lifting heavy things, icing, working on range of motion, etc) has really helped me. I know everyone is different & that my perspective is probably VERY different than many folks' perspective. I'm so thrilled with where I am right now & am really glad that I had this done.
Hope it helps. Good luck!
