Steve,
Sorry I didn't clarify more. Dr. Ketchum's site does reference dermal fasciectomies, which are probably more invasive. However he recommended for my husband removing sections/segments of the cords and then applying skin grafts "strips" in place of the palm skin. He drew on his hands with a pen where he would do this and it was definitely minimal surgery as compared to his four previous fasciectomies. He was familiar with the McCashin (sic?) method that was done once on his left hand and referred to it as much more difficult of a recovery. He gave some patient references to call, which we are going to do. We just went this past Tuesday, so have not scheduled anything as yet.

I am not an expert. Mary Beth's post reminded me of the
procedure referred to as "establishing a fire break" by
grafting epithelium (skin) from a non involved site. The
benefit. presumeably, being non DD DNA. (One does not have
DD of the buttocks or groin.) Randy's report does not seem
to reference a graft; instead it sounds like tertiary intention, or "granulating in." If so, that means the
same old, same old growing back into the wound. If DD
involves DNA of the aponeurosis and adjacent tissues,
then, fire breaks make sense. Granulating in would more
likely result in scar tissue and recurrence. All this
is conjecture, because I was not there and have no direct
knowledge of the circumstances. Food for thought, perhaps.
NA involves neither above form of wound healing; nor does it
remove the "offending" tissue (no fire break.)It does
interrupt the DD process with minimally aggravating circumstances. Imagine chewing gum adhering the sole of
your shoe to the floor. NA cuts through the gum and leaves
remnants on both sole and floor. In time the fibers reconnect. Hand surgery removes much of the "offending"
tissue; and, triggers wound healing. Without a "fire break"
the condition recurs because the underlying source remains.
Feel free to correct any inaccuracies or mis-statements. The
above is my opinion, not irrefutable science. Final thought:
collagenase would dissolve (some?) of the chewing gum and
allow separation of the fascia from the tendon-aponeneurosis
interface. Presumeaably, the chewing gum fibers re-connect
over time.

"McCash's approach was to make incisions in the transverse skin creases and to move the undermined skin bridges so the skin shortage is transferred to the distal palmer crease incision which remains wide open. Only the diseased fascia has to be removed. The open wound is dressed at a weekly interval. The wounds generally close in 2-5 weeks and since they remain open, there is no possibility for a haematoma to collect. A disadvantage of the open palm technique is that patients are apprehensive about the open wound. The great merit of the method is its safety."

My surgeon said he might use the McCash method depending on the elasticity of my skin.

Stage one,
I agree with much of your post. From my experience with friends, research and talking with hand surgeons, a persons diathesis has as much, or more to do with recurrence than does a particular procedure.
I think that is the root of all the name calling and differing opinions on this website. If everyone had the same diathesis, then it would be easy to evaluate the different procedures. As we know, with Dupuytren's, each patient is different. In my case, I had as good of an outcome as a person could possibly have from any procedure. I had a limited fasciectomy. Someone with a different diathesis might have had a completely different outcome. Same with NA. Probably the same with any surgical procedure.
