Il est clair que l’emboiture pour le membre supérieur doit être en 2 partie:

– Une partie souple qui permettrait la pro-supination (cuir?)

-Une partie dur sur laquelle sera fixée la main

For sure, an upper limb socket should be available in 2 parts:

– A stretchable part that allows the rotation of the wirst

– A hard part to attached the hand

Snaps for a gel liner: http://www.utaharm.com/files/ then choose  “Resources, product catalog” and go to page 9, bottom, item # 3010426.  I think that the 6 cost around $150, but you’d need to call them to see.
