Upper limbs


Different kinds of attachment sockets

With silicone liner:

We apply  to the upper limb our acquired  knowledge for the manufacture  of silicone liners for the lower limb.

The woven silicon liner with terminal fixing, made through molding, Is rolled  onto the skin. It then just needs to be rolled onto the prosthesis. It Is held in place by a lock attached to the end of the socket.

There are prefabricated silicone liners as well that work on the same principle. The choice between the two types of liner will be based on the appearance of the stump.

The fastening systems may be the same for both the prosthetic arms and the forearm.

For forearm attachment this type of fixing allows for a lot less restriction on top of epicondyles (above the elbow).

For the prosthetic arm it removes the need for the harness holding.


Single socket (without liner)

When there is no fixing liner to maintain the prosthesis  in place we must use other methods:

For the forearm prostheses, the edges of the socket must be tightened to clamp to the arm above the epicondyles (the elbow) to assure the maintenance of the prosthesis.

For prosthetic arms a system of straps and harnesses has to be used, attached to the implant from under the opposite arm at the back.

These sockets can be made of resins or semi-flexible plastic materials.
