Fill the undercut with wet plaster.
5.1.2 Fabricating a Check Socket
>
Required tools and materials:
755T4=360 Outer Ring, 755X104=360 Vacuum Tube (with vacuum seal­
ing ring), 755E9 Vacuum Pump, 756D2, 756B12=* or 756B20=* Oscil­
lating Saw, 616T52=* ThermoLyn rigid or 616T83=* ThermoLyn clear,
string
1) Prepare for fabrication of the prosthetic socket (see Page 19).
2) Position two pieces of string crosswise on the lamination adapter (see
fig. 5). The pieces of string form air channels that make it easier to
mould the vacuum forming material to the contours.
3) Complete the vacuum forming process with ThermoLyn.
4) Finish the prosthetic socket (see Page 22).
5.1.3 Laminating a Transtibial Socket
> Required tools and materials:
99B81=70X19X5 and 99B81=100X19X5 PVA Bag, 623T3=8 or
623T3=10 Perlon Stockinette, 81A1=8 or 81A1=10 Tube Sock,
616B1=25x* Carbon Fibre Cloth Strap, 616G2 Carbon UD Hose,
616G15 Carbon Fibre Woven Hose, 617H119 Orthocryl Lamination
Resin 80:20 PRO, string
1) Prepare for fabrication of the prosthetic socket (see Page 19).
2) Soak the shorter PVA bag and pull it over the plaster positive.
3) Pull a tube sock over the plaster positive.
4) Place a layer of carbon fibre cloth strap circularly around the MPT
(middle patellar tendon) point (see fig. 6).
5) Position a layer of carbon fibre cloth strap medially and laterally from the
shuttle lock up to the condyles (see fig. 7).
6) Place a layer of carbon fibre cloth strap anteriorly and posteriorly from
the shuttle lock to the circular carbon fibre cloth strap (see fig. 8).
7) Pull a tube sock over the plaster positive.
8) Loop a piece of string around the lamination adapter in the groove and
tie tightly (see fig. 9).
9) Cut a piece of carbon UD hose (1.5 times the length of the plaster posit­
ive).
10) Pull the carbon UD hose over the plaster positive up to the socket edge.
Tie the upper section of the carbon UD hose and fold the remaining
length over the plaster positive.
