5.5.3 Fabricating the Prosthetic Socket
INFORMATION
The instructions for fabricating the prosthetic socket are intended only for the 3R62=KD Pros­
thetic Knee Joint.
5.5.3.1 Fabricating the Test Socket
Laminating the Prosthetic Socket
Required materials:
>
640Z5* Plaster Insulating Cream, 623T3* Perlon Stockinette, 616G13* Woven Fibreglass
Stockinette, 616G12* Carbon Fibre Cloth, 617H19* Orthocryl Lamination Resin, 617H17*
Orthocryl soft, 4G70 Lamination Anchor
1) Apply plaster insulating cream to the plaster positive.
2) Cut a piece of Perlon stockinette to twice the length of the plaster positive and pull on one
half.
3) Twist the Perlon stockinette on the distal end and pull on the other half.
4) Cut a piece of woven fibreglass stockinette to the corresponding length and pull on the length
equal to two-thirds of the prosthetic socket.
5) Tie off the woven fibreglass stockinette on the distal end and pull on the length equal to half
the prosthetic socket.
6) 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.
7) Position the two pieces on the distal area of the plaster positive.
8) Cut a piece of Perlon stockinette to twice the length of the plaster positive and pull on one
half.
9) Twist the Perlon stockinette on the distal end and pull on the other half.
10) 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.
11) Cut a piece of Perlon stockinette to twice the length of the plaster positive and pull on one
half.
12) Twist the Perlon stockinette on the distal end and pull on the other half.
13) Cast the prosthetic socket with Orthocryl soft and allow it to cure.
Applying the Lamination Anchor
Required materials:
>
636K8=20x2x10 Plastaband, Adhesive Putty (consisting of: 639A1=1 Talcum, 617H21* Ortho­
cryl Sealing Resin, 617P37=0.150 Hardener Powder), 627B2* Monofilament Adhesive Tape
1) Bend the lamination anchor to fit the prosthetic socket.
2) Fill the coupling opening of the lamination anchor with Plastaband.
3) Position the lamination anchor on the prosthetic socket and glue it in place with adhesive
putty.
4) Secure the glued lamination anchor to the prosthetic socket with adhesive tape.
5) Bring the prosthetic knee joint to full flexion. If necessary, form the required contact surface
on the prosthetic socket with putty. It is also possible to glue a stop bumper of Pedilin onto
the outer laminate.
