I had Dupuytren’s Contracture in both hands. In one hand I had surgery, which I strongly recommend avoiding. In the second hand, one hand specialist recommended the injection treatment; I didn’t like that because it wasn’t clear that the enzyme wouldn’t also make my tendons weaker, and the recovery took a while. I found another hand surgeon who did needling, which I went with, and highly recommend. Basically he used a needle to snap the growth in my hand. It was painless, and if I remember correctly, it took about 30-45 minutes, and my hand flattened out immediately. There is no lengthy recovery (I was surfing the next day). Unfortunately you can’t do needling on a hand that has already had surgery.
