Molly--
We have had excellent results using American Plastics' SemiFlex (aka
bioElastic plastic). We gave up using PE long ago due to shrinkage and it
really isn't all that flexible.
My patient has been using a suralyn 1/4 draped molded
check socket now for several months.
Surlyn cold flows and if a scratch occurs it will eventually fail along the
scratch.
The finished product will be bubbled molded with a carbon frame (no cutouts).
Am looking for a flexible proximal edge. >>
You did not specify what style socket--Quad-ish or ischial containment-ish???
Why have a flexible socket if you don't let it flex? (A flexible socket
surrounded by a frame is still hard...) All of our flexFrame sockets are cut
out in the posterior and windowed in the anterior. This is extremely
comfortable--cooler that standard design; allows the muscles to expand as you
walk; allows the socket to collapse when sitting making that activity more
comfortable as well. Just make sure the plastic is at least 3/16 thick over
the medial ischial support (if ischial containment-ish) and has a frame
strut up over it for support.
I wear one of these myself and wouldn't go back to a hard socket.
