2) Conduct the dynamic trial fitting.
3) If required, modify the alignment in regards to plantar flexion and dorsal flexion as well as
pronation and supination by inserting small spacers into the shoe.
4) If the positioning of the prosthetic socket to the footplate has to be corrected, follow the
instructions for separating the components in the section "Definitive Gluing of the Prosthetic
Components" (see Page 18) – heading "Preparing the prosthetic socket and the footplate for
gluing" and then continue with the instructions in the section "Preparing the Prosthesis for the
Trial Fitting" (see Page 16), – heading "Clamping in the alignment apparatus", taking into
account the corrections.
5) Repeat the dynamic trial fitting and correct the footplate position until the prosthesis wearer
exhibits a harmonious gait pattern and can walk physiologically and without stress.
5.6 Definitive Gluing of the Prosthetic Components
Creating the mould (photos see 646T113*, Section 3.4.1)
1) Open but do not remove the cover on component A in order to prevent the formation of over­
pressure during heating.
2) Warm component A in the heating oven in order to decrystallise it (min. 3 h at 65 °C / 149 °F).
3) The processing time for the polyurethane can be extended by cooling it (min. > 17 °C /
> 62.6 °F).
4) Remove any pads that are positioned and/or secured on the prosthetic socket.
5) Pull the crepe sole off the footplate.
6) Remove glue residue from the footplate.
7) Remove the white adhesive tape from the prosthetic socket.
8) Grind the putty until it is straight to slightly concave.
9) The shape that is achieved by grinding will be the shape of the PU glued joint.
10) Grinding must result in a shape that permits the fitting of a footshell.
11) Clamp the prosthesis so it faces up at an angle of approximately 40°, with the toes pointing
down.
12) Use a cloth to practise the application of the polyethylene plate to the heel area of the pros­
thesis.
13) Use isopropyl alcohol to clean both sides of the polyethylene plate.
14) Heat the polyethylene plate at 130 °C (266 °F) until it becomes transparent and can be moul­
ded.
15) Remove it from the heating oven wearing temperature-resistant gloves.
16) Apply the polyethylene plate over the heel of the prosthesis (1/2 over the prosthetic socket,
1/2 over the footplate).
17) Mould the heated material. In doing so, avoid excessive undercutting and close the dorsal
region by butting the edges up against each other rather than overlapping them.
18) Do not squeeze the polyethylene tight together in the dorsal area.
19) Apply the polyethylene plate carefully in the region with the putty.
20) Mould the polyethylene plate on the sides, in the anterior area of the footplate.
21) The mould has to firmly encompass the edges of the footplate and the edge in the heel area of
the prosthesis, so that the footplate and the prosthesis are kept in their correct position to
each other later during casting.
22) Allow the mould to cool.
23) Mark the trimming edge so that the edges of the mould hold the footplate and the prosthetic
socket in place.
24) Expose the dorsal area of the prosthesis so the polyurethane can be poured in later.
25) Trim the mould so that the prosthesis can be removed.
26) Remove the prosthesis from the mould.
