PRO, string, 627B40 polyethylene adhesive tape
1) Prepare for fabrication of the prosthetic socket (see Page 24).
2) Cut a piece of Perlon stockinette (twice the length of the plaster model).
3) Pull the Perlon stockinette over the plaster model to the edge. Tie off the
second half of the Perlon stockinette and fold it over the plaster model
(see fig. 10).
4) Expose the valve dummy using a scalpel (see fig. 11).
5) Wrap string around the valve dummy and tie the Perlon stockinette off
tightly in the distal groove of the cylinder body (see fig. 12).
6) INFORMATION: Tie this off tightly so the prosthetic socket is air­
tight after the lamination process.
Tie off the two layers of Perlon stockinette in the undercut of the cylinder
body so they are up against the cylinder body (see fig. 13).
7) Position a layer of carbon fibre cloth strap from the medial condyle over
the cylinder body to the lateral condyle (see fig. 14).
8) Position a layer of carbon fibre cloth strap from the MPT (mid-patella-ten­
don) point over the cylinder body to the opening for the back of the knee
(see fig. 15).
9) Position a layer of carbon fibre cloth strap circularly at the height of the
MPT (mid-patella-tendon) point (see fig. 16).
10) Pull a nylon stockinette over the plaster model.
11) Expose the valve dummy.
12) Wrap string around the valve dummy and tie the nylon stockinette off
tightly in the distal groove of the cylinder body (see fig. 17).
13) Tie the nylon stockinette off tightly in the undercut of the cylinder body
with Perlon string (see fig. 18).
14) Cut off a piece of carbon fibre stockinette (1.3 times the length of the
plaster model).
15) Pull the carbon fibre stockinette over the plaster model to the edge (see
fig. 19).
16) Tie off the excess carbon fibre stockinette at the distal end and fold it
over the plaster model (see fig. 20).
17) Tie off the carbon fibre stockinette tightly in the distal groove of the cylin­
der body.
18) Tie off the carbon fibre stockinette tightly in the undercut of the cylinder
body using Perlon string.
