5.5.3.2 Fabricating the Definitive Socket
> Required materials:
4x 501T1=M5X16 Truss Head Screw, 4x 502R1=M5X16 Two Hole Nut, 616G12* Carbon
Fibre Woven Fabric, 623T3* Perlon Stockinette, 616G13* Woven Fibreglass Stockinette,
617H19* Orthocryl Lamination Resin, 617H17* Orthocryl soft, 4G70 Lamination Anchor
1) Secure the connection between the lamination anchor and prosthetic socket with the help of
the truss head screws
2) INFORMATION: For stability, a different alignment of the carbon fibres and an overlap
of 3 cm to the edge of the lamination anchor are important.
Cut two pieces of carbon fibre cloth to size as a mat according to the edge of the lamination
anchor.
3) Position the two pieces on the lamination anchor.
4) Cut a piece of Perlon stockinette to twice the length of the plaster positive and pull on one
half.
5) Twist the Perlon stockinette on the distal end and pull on the other half.
6) Cut a piece of woven fibreglass stockinette to the corresponding length and pull on the length
equal to two-thirds of the prosthetic socket.
7) Tie off the woven fibreglass stockinette on the distal end and pull on the length equal to half
the prosthetic socket.
8) INFORMATION: The double casting process is used for lamination.
Cast the distal section of the prosthetic socket (2/3 of the length) with Orthocryl lamination
resin and allow it to cure.
9) Cut a piece of Perlon stockinette to twice the length of the plaster positive and pull on one
half.
10) Twist the Perlon stockinette on the distal end and pull on the other half.
11) Cast the prosthetic socket with Orthocryl soft and allow it to cure.
5.6 Static Alignment
+ = anterior placement / – = posterior placement (in relation to the load line)
No. see fig. 9
Required equipment:
743L100 L.A.S.A.R. Posture
To determine the sagittal load line
• Prosthetic foot (with shoe) on force measurement plate (sufficient load: > 35% body weight)
• Other foot (with shoe) on height compensation plate
• The tips of the shoes are in one line
Optimise the static alignment solely by changing the plantar flexion. Adjustment is performed only
with the anterior and posterior set screws of the tube adapter on the prosthetic foot.
