Elaine..Unfortunately yes, my dominant hand. I am waiting to have surgery for the sagittal band tear, putting it off as long as possible as it may stir up the Dupuytren's. Right now my hand is in a yoke stabilization brace so it doesn't get worse. As far as the Dupuytren's, right now it is in the inactive stage. I see the top Dupuytren's specialist in the United States every three months. If it starts to contract, he will send me immediately for Radiotherapy treatment. I've already been tattooed and had the hand mold made, so if need be, I can start the treatment immediately. Nothing I can do about it. It is what it is...(it's been a really bad year for me to say the least).Just looked both of these conditions up… ouch. In fact, double-ouch. They must really limit you in terms of what you're able to do. And I'm guessing all of this is going on in your dominant hand?
