4.2 Combination possibilities
INFORMATION
In a prosthesis, all prosthetic components have to meet the patient's requirements regarding the
amputation level, body weight, activity level, environmental conditions and field of application.
4.3 Adjustments and final assembly
4.3.1 Socket fabrication 3R106=KD
4.3.1.1 Lamination prior to trial fitting
Take a piece of 623T3 Perlon Stockinette twice the length of the plaster model and pull half of
it over the isolated socket. Twist the other half of the stockinette on the distal end and reflect it
over the socket.
In order to absorb strong forces in the area of the modular knee joint, the socket must be gradu-
ally reinforced with 616G13 Fiberglass Stockinette. To do this, pull over the first layer to
socket length, tie it off and then reflect it up to half of the socket length.
Put 2 layers of 616G12 Carbon-Fiber Cloth on the distal area so as to provide an underlying base
with a projecting brim of 3 cm around the 4G70 Adapter, which will be mounted later in the procedure.
Pull on two layers of 623T3 Perlon Stockinette.
The socket lamination is performed in two stages. In the first stage the socket is laminated up to
/ of its length with 617H19 Orthocryl Lamination Resin. In the second stage the proximal part

of the socket is laminated with 617H17 Orthocryl Flexible Resin.
Once the first casting has hardened, pull on 2 more layers of 623T3 Perlon Stockinette before
laminating the proximal part of the socket with 617H17 Orthocryl Flexible Resin.
4.3.1.2 Applying the lamination anchor
Prior to gluing, prepare the correctly adapted lamination anchor with the residual limb bedding.
To do so, fill the coupling opening with 636K8 Plastaband (Fig. 3). Clamp residual limb bedding
and joint into the alignment apparatus.
Attention!
Remove soft, flexible or porous materials from beneath the support surface of the lami-
nation anchor. Mix the putty exclusively from 617H21 Orthocryl Sealing Resin and
639A1 Talcum Powder. Then glue on the lamination anchor.
Secure with 627B2 Adhesive Tape for trial fitting. Test the stop function. If necessary, form the
required contact surface with putty. If need be, glue an extension stop made of Pedilin onto the
outer laminate.
4.3.1.3 Socket completion
Once the trial fitting has been completed, fasten the lamination anchor to the socket with truss
head screws (Fig. 1, (3)) and two-hole nuts (Fig. 1, (2)). Then laminate. Proceed with further re-
inforcement as follows: Two layers of 616G12 Carbon Fiber Cloth must be sandwiched between
two layers of 623T3 Perlon Stockinette. To achieve this, pull one layer of 623T3 Perlon Stockinette
over the whole socket and tie it circularly at the top. Apply two layers of 616G12 Carbon Fiber
Cloth over the arms of the 4G70 Adapter. Pull the remaining half of the 623T3 Perlon Stockinette
back over the carbon fiber layers. Gradually reinforce the socket again with 616G13 Fiberglass
Stockinette (as described in point 4.3.1.1). As a final step, pull over 2 layers of Perlon Stockinette
623T3. Proceed with lamination as in the first casting.
