TT bench alignment
Required materials: 662M4 goniometer, 743S12 heel height measuring apparatus, 743A80
50:50 gauge, alignment apparatus (e.g. 743L200 L.A.S.A.R. Assembly or 743A200 PROS.A.
Assembly)
Assemble and align the prosthetic components in the alignment apparatus according to the fol­
lowing specifications:
Heel height: effective heel height (shoe heel height - sole thickness of forefoot)
+ 5 mm
Sagittal alignment: alignment reference line on a–p markings of the footshell
(see fig. 5)
Frontal alignment: alignment reference line on m–l markings of the footshell (see
fig. 5)
Connect the prosthetic foot and prosthetic socket using the selected adapters. Follow
the adapter instructions for use.
Sagittal alignment:
Determine the centre of the prosthetic socket with the 50:50 gauge. Align the pros­
thetic socket centrally to the alignment reference line.
Socket flexion: individual residual limb flexion + 5°
Observe the abduction or adduction position.
TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.
5.2.3 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 prostheses: 646F219*, TT
•
modular leg prostheses: 646F336*) may be requested from Ottobock.
5.2.4 Installing the socket connector (Harmony only)
The vacuum pump is connected to the prosthetic socket by a socket connector. The hose can
either be considerably shortened or wrapped around the adapter to secure it closely on the pros­
thesis.
1) Install the 2R117 socket connector according to the corresponding instructions for use.
2) Shorten the hose of the socket connector to the optimal length and connect it to the vacuum
pump (see fig. 8, see fig. 9).
5.2.5 Dynamic Trial Fitting
• Adapt the alignment of the prosthesis in the frontal plane and the sagittal plane (e.g. by mak­
ing 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.
5.2.5.1 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. Heel wedges of various hardness are included in
the scope of delivery.
