Dear List,
I would like to find out what is your preferred material for flexible inner
sockets for transfemoral prostheses with locking gel liner suspension (pins,
not KISS). I always preferred Proflex-with-silicone and still use it for all
full suction as well as KISS type suspensions, however, it does not always
work well with shuttle locks. Cylindrical or almost cylindrical shapes of
the residual limbs are among the types that don’t like Proflex. In my
opinion, Proflex has higher coefficient of friction as compared to
Durrplex/Vivak used for check sockets, so when you transfer a successfully
fitted check socket into Proflex material, the limb does not slide in as
easily and the fit changes drastically. For these types of limbs I
successfully use low density polyethylene, as it is almost as smooth as
Durrplex, however it does not have the elastic qualities of Proflex. So,
what is your preferred material for such residual limbs?
Regards,
Stephan
