Randy, that's sad but probably true. I guess it needs a lot of education until the knowledge about therapies is spread within the medical community. This is also the reason why we started the German Dupuytren Society. We want to inform medical doctors and patients. Not suprisingly patients are more motivated to learn about new therapies. I guess us patients have to spread the news ... luckily enough we have the Internet and a forum like this.

Though it is not fully understood why radiotherapy is efficient, I belive that it works similar to collagenase injection. In initial stage Dupuytren it dissolves the nodule and it often disappears completely. I later stages it softens the nodule and stops or slows down the growth. My guess it that the radiation damages the collagen lump to an extent that the body can dissolve it. If it is gone, the recurrence rate is very low.

That as an add-on comment to the comparison of NA/surgery/collagenase in the "cannot bend hand" thread.
