3) Place the socket in the lamination anchor and align it.
Position the drawn on line in the medial third of the prosthetic foot from the frontal perspect­
ive.
Align the posterior end of the socket in a natural line with the heel from the sagittal perspect­
ive.
4) Adapt the arms of the lamination anchor to the shape of the residual limb using the bending
iron (see fig. 10).
5) Roughen the distal socket end.
6) Clean the lamination anchor using a degreasing cleaner.
7) Protect the prosthetic foot from dirt by covering it.
8) Create a thick mixture of sealing resin and talcum.
9) Apply the sealing resin and talcum mixture to the lamination anchor and the socket, evening
out any small differences in height.
10) Position the socket on the lamination anchor, align it and leave the sealing resin and talcum
mixture to harden.
11) Take the prosthesis out of the alignment apparatus.
12) Create a thick mixture of sealing resin and talcum.
13) Apply the resin-talcum mixture in the region of the anchor arms for support and smooth it (see
fig. 11).
14) Leave the resin-talcum mixture to harden.
15) Wrap glass-fibre reinforced adhesive tape or Cellacast circularly around the area of the
anchor arms and secure it.
5.2.4 Installing the footshell
Required tools and materials:
>
Footshell, foam for inserting into cavities in the forefoot, sanding tool
1) Sand down the foam for fitting in cavities in the forefoot region.
2) Optional: Cut the footshell in the proximal area and sand it to fit the shape of the socket.
3) Put the footshell on the prosthetic foot until it clicks onto the heel spring and slide the foam
into the forefoot area.
5.3 Dynamic Trial Fitting
The alignment of the prosthetic foot is checked and corrected during the dynamic trial fitting. If
additional lateralisation of the prosthetic foot is necessary, the lamination anchor must be reposi­
tioned on the prosthetic socket.
> Inform the patient that the foot is only provisionally secured to the prosthetic socket.
1) Check the length of the prosthesis and the alignment of the prosthetic foot.
2) If necessary: Adjust the alignment of the prosthetic foot (see Page 17).
5.3.1 Aligning the prosthetic foot
The positioning of the foot relative to the prosthetic socket can be adjusted by moving the lamina­
tion anchor. The following adjustments can be made:
Plantar flexion/dorsiflexion: ±6 °
•
Rotation: ±30 °
•
Adduction/abduction: ±6 °
•
Required tools and materials:
>
710D4 Torque Wrench
1) Loosen the fine-threaded screw until the lamination anchor can be moved.
2) Adjust the setting aid towards the anterior for maximum plantar flexion or towards the posteri­
or for maximum dorsiflexion (see fig. 2).
3) Click the setting aid in to the guiding groove.
4) Adjust for the desired adduction or abduction.
