5.1 Preparing for socket fabrication
> Required materials: Hemispherical dummy, plaster screw,
99B81* PVA bag
1) NOTICE! Align the shuttle lock with the longitudinal axis of
the residual limb to prevent unnecessary load and wear (see
fig. 3).
Position the hemispherical dummy on the distal surface of the
plaster model along the longitudinal axis of the residual limb and
loosely secure it with the plaster screw.
2) Pull a soaked PVA bag over the plaster model.
3) Fabricate the prosthetic socket (see Page 12).
5.2 Fabricating the prosthetic socket
INFORMATION
The layup described in this document was approved for the maxim­
um product user body weight. The prosthetist assumes full respons­
ibility for any change to the layup.
5.2.1 Laminating a transfemoral socket
> Required materials: 710D4 torque wrench, 711S4* bending
iron, 616G6 Dacron felt, 623T3 Perlon stockinette, 616B1 carbon
fibre cloth strap, 616G12 carbon fibre cloth, 616G4 fibreglass
mat, 616G15 carbon fibre woven hose, 99B81 PVA bag,
617H119 Orthocryl lamination resin 80:20 PRO
1) Cut 1 layer of Dacron felt to size and position it on the model.
2) Pull 2 layers of Perlon stockinette over the model and tie it off on
the hemispherical dummy.
3) Position 2 layers of carbon fibre cloth strap (width: 5 cm) circu­
larly 3 cm below the perineum.
4) Medially and laterally, position 1 layer of carbon fibre cloth strap
(width: 5 cm) respectively from the hemispherical dummy to the
socket brim.

5) Anterior and posterior, position 1 layer of carbon fibre cloth
strap (width: 5 cm) respectively from the hemispherical dummy to
the socket brim.
6) Position 4 strips (approx. 5 cm x 3 cm) of fibreglass mat on the
carbon fibre cloth strap to line the anchor arms.
7) Position 2 layers of carbon fibre cloth (e.g. 15 cm x 15 cm) offset
over the ischium containment.
8) Pull 2 layers of Perlon stockinette over the model and tie it off on
the hemispherical dummy.
9) Screw the shuttle lock fully into the lamination anchor and tighten
the screw of the threaded clamping (torque value: 10 Nm).
10) Position the lamination anchor on the hemispherical dummy.
11) Bring the lamination anchor arms to the correct a-p and m-l posi­
tion. Never align the threaded clamping in the anterior or posteri­
or direction.
12) Optional: Adapt the anchor arms of the lamination anchor to the
model with a bending iron.
13) Replace the shuttle lock with the lamination dummy (see
Page 13).
14) Wrap the clamping section of the lamination anchor with plasta
tape to prevent contact with the lamination resin. This ensures
even clamping.
15) Place 2 layers of carbon fibre cloth (e.g. 15 cm x 15 cm) offset
over the lamination anchor arms.
16) Pull 2 layers of Perlon stockinette over the model and tie off below
the cap screw of the lamination anchor.
17) Pull 2 layers of carbon fibre woven hose over the model and tie off
below the cap screw of the lamination anchor.
18) Pull 2 layers of Perlon stockinette over the model and tie off below
the cap screw of the lamination anchor.
19) Pull a soaked PVA bag over the model.
20) Complete the lamination process with Orthocryl lamination resin.
