Pretty Much just like that, " Could you please install these 2 implants 5mm or more apart safely in my hand where my anatomy will allow "
Yes, idealy you want them to have their own “tunnel” to sit in, also you will wan’t to firmly tape down some splints to keep them in place ( Sing out if you need more info around this )
If you are talking about the Usual spot aka thumb webbing aka Thenar aka Position #0 it will come down to your own anatomy.
Here is MY theory to place evenly either side of centreline
I would suggest you measure from the edge of the second metacarpal ( Pointer ) toward the first metacarpal ( Thumb ) to where you deem YOUR anatomy would limit placement.
If 25mm was the figure you were looking at, you could place your 1st implant @ 8.3mm from the 2nd Metacarpal and your 2nd Implant @ 16.6mm from the 2nd Metacarpal.
If your measurement was 20mm you could place your 1st implant @ 6.6mm from the 2nd Metacarpal and your 2nd Implant @ 13.3mm from the 2nd Metacarpal.
Remember, this is where you want your implants to end up, so plan for this from your insertion points
This is a mathematical approach, but realistically a professional piercer, given the information and requirements >5mm etc. will be better at finding a suitable location for YOUR anatomy, but this theory should be a good starting point
The forum is pretty light on this information, So before answering this;
Is this for an xSeries?
A flex with Flex Needle install?
A Flex with scalpel install?
