FYI I had Kenalog injections in palm lump and at pip joint some months after NA. It took a couple of weeks to notice a difference. I think the lump shrank some and certainly did not progress. Pip joint is staying about the same. Why not email pictures to Eaton or Denkler and they will comment on whether it would be a good idea.

"What do you mean 'does the same' as NA?"

Joe,

It renders the same results with a similar method.

NA and the Collegenase injections have a lot in common compared to conventional Open Surgery (OS). The idea is to weaken the cords at a few points and bend the finger back straight, causing the cord to break. Collegenase does this by dissolving the cord, NA does it with the sharp end of a syringe. Either way, the finger goes free.

I would estimate that world wide about 20,000 fingers have been straightened over the last 35 years with NA, compared to abut 50 fingers straighten with experimental Collegenase. While Collegenase seems to have promise to surpass what NA can do, it is still not available. NA has proven to be very safe and effective. Neither Collegenase or NA are a replacement for OS. They are entry level first treatments before resorting to the far more invasive OS.

American CHS are generally keen on Collegenase but *not* on NA. They remain curiously oblivious to the work of Charles Eaton/Denkler/Press on NA's safety and effectiveness. Looks like a standard case of Head In Sand disease within that profession.
