Hello,
Yes, I have fit several 3S systems on Above-Elbow Amps. Based on what you
have said about the limitations of the sound side, I would be very cautious
about using a 3S because it would be very difficult to become independent in
donning. I assume that the donning problem is in getting the silicone liner
on the residuum and not getting the attachment pin to engage in the lock (
assuming you are using some type of shuttle lock). Of course I have been
amazed, from time to time, at how inventive some patients can be in learning
to don a prosthesis and if this man, along with your help, is able to find a
way to donn the liner, I would be very interested in seeing it.
If there is also a problem getting the pin fully into the lock I can recommend
2 things. One, cut a hole in the rigid socket to allow his fingers to pull
and guide the pin into position; and Two, use a clutch lock that allows him to
“pull-in” by turning the release button.
Good Luck,
