Has anyone had the standard 3-injection treatment without success?

I had very good response with these injections on a 30 degree contraction of the ring finger. Dr. Ketchum very skillfully injected along the underside of the skin. This essentially cured my right hand for about 12 years (now age 55). Still no sign!

Now under treatment on my left hand after a severe finger injury "ignited" Dupuytren's. Result looks good.

[6 week serial basis w/ 1-3 cc of triamcinolone (40 mg/ml)]
