• If necessary, the alignment recommendations (TF modular leg pros­
theses: 646F219*, TT modular leg prostheses: 646F336*) may be
requested from Ottobock.
5.1.4 Dynamic Trial Fitting
• Adapt the alignment of the prosthesis in the frontal plane and the sagittal
plane (e.g. by making angle or slide adjustments) to ensure an optimum
gait pattern.
TT fittings: Make sure that physiological knee movement in the sagittal
•
and frontal plane is achieved when the leg begins to bear weight after
the heel strike. Avoid medial movement of the knee joint. If the knee joint
moves in the medial direction in the first half of the stance phase, move
the prosthetic foot in the medial direction. If the medial movement occurs
in the second half of the stance phase, reduce the exterior rotation of the
prosthetic foot.
• Remove the plastic protector from the pyramid after completing the
dynamic fitting and the walking exercises.
5.2 Optional: Installing the foam cover
The foam cover sits between the prosthetic socket and prosthetic foot. It is
cut longer in order to compensate for the movements of the prosthetic foot
and prosthetic knee joint. During flexion of the prosthetic knee joint, the foam
cover undergoes posterior compression and anterior elongation. The foam
cover should be stretched as little as possible in order to increase its service
life. There is a connecting element (such as a connection plate, connection
cap or connection cover) on the prosthetic foot.
Required materials: degreasing cleaner (e.g. 634A58 isopropyl alco­
>
hol), 636N9 contact adhesive or 636W17 plastic adhesive
1) Measure the length of the foam cover on the prosthesis and add the
length allowance.
TT prostheses: Distal allowance for movement of the prosthetic foot.
TF prostheses: Allowance proximal of the knee rotation point for flexion
of the prosthetic knee joint and distal allowance for movement of the
prosthetic foot.
2) Cut the pre-shaped foam cover to length and fit it in the proximal area on
the prosthetic socket.
3) Pull the foam cover over the prosthesis.
4) Set the connecting element onto the footshell or prosthetic foot. Depend­
ing on the version, the connecting element engages in the edge or rests
on the foot adapter.
5) Install the prosthetic foot on the prosthesis.
