Be careful how you read that webmasters response.
It says : "There is no difference between needle aponevrotomy and NEEDLE fasciotomy".
So, he is not addressing the difference between NA and surgical fasciotomy.

I would think 'needle fasciotomy' is a misnomer, although a surgeon over here uses the 'subcutaneous fasciotomy' for NA.

If you do a quick search on the net, you might find the following definitions :

Fasciotomy :surgical incision of a fascia

Fascia : a sheet of connective tissue (as an aponeurosis) covering or binding together body structures : also : tissue occurring in such a sheet / or / A sheet or band of fibrous connective tissue enveloping, separating, or binding together muscles, organs, and other soft structures of the body

Fasciectomy : surgical excision of strips of fascia

Apeunorectomy : Excision of an aponeurosis
Also called by some : 'Aponovrotomy', 'Subcutaneous (just under the skin) fasciotomy', and maybe other.

Aponeurosis : A sheetlike fibrous membrane, resembling a flattened tendon, that serves as a fascia to bind muscles together or as a means of connecting muscle to bone

Interpretation of all this ? I leave it up to you.
No idea what the AMA sees in all this, being Belgian myself :)
