I have had Dupuytren's for the past 10 years (I'm 55 now). The ring finger of my right hand is effected. until about 2 years ago, it was taking the classic path with the finger curving toward the palm of my hand.

But two years ago, I was working out with a trainer who didn't know about my hand (I've made other trainers aware of it since i require weights to grip in order to do things like push-ups or any other exercise that requires a flat hand). She threw a boxing bag at me, and caught my hand HARD. It pushed the finger way back, and it almost felt like the tendon just snapped. It ached for months.

Since then, my finger is completely straight, but sunken. It works fine, the pain is gone, but when i hold my hand out straight, you can see that the ring finger sinks lower than the others.

My question is, can a serious blow to your hand stop the progression of the disease? I'm feeling lucky (now that the pain is gone), although I'm a little concerned about the new lumps in my feet :(
