TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.
5.1.3 Static Alignment
• Ottobock recommends checking the alignment of the prosthesis using
the L.A.S.A.R. Posture and adapting it as needed.
• 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 adapter cover from the prosthetic foot after completion of
the dynamic trial fitting and gait training exercises.
5.1.4.1 Optimising the heel characteristics
The behaviour of the prosthetic foot at heel strike and during heel contact in
the mid-stance phase can be adapted by replacing the heel wedge. The
prosthetic foot is delivered with 3 heel wedges.
Hardness of the heel wedges: The heel wedges are colour-coded:
(transparent=soft, grey=medium, black=hard). Ottobock recommends start­
ing with the grey heel wedge.
1) Pull the prosthetic foot apart slightly and remove the existing heel
wedge.
2) Align the other heel wedge so the Ottobock lettering is the right way up
and the tip points to anterior.
3) Insert the heel wedge into the prosthetic foot (see fig. 3).
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
