Ottobock 1S49 SACH Gebrauchsanweisung Seite 17

Anterior placement, middle of the prosthetic foot to the alignment reference
line: 30 mm
Connect the prosthetic foot and prosthetic socket using the chosen adapters.
The instructions for use of the adapters must be observed.
Determine the centre of the prosthetic socket with the 50:50 gauge. Align the
prosthetic socket centrally to the alignment reference line.
Socket flexion: Individual residual limb flexion + 5°
Frontal plane
Alignment reference line of prosthetic foot: between big toe and second
toe
Alignment reference line of prosthetic socket: along the lateral patella
edge
Observe the abduction or adduction position.
TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.
5.3.2 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.
5.3.3 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, medial­
ise the prosthetic foot. If the medial movement occurs in the second half
of the stance phase, reduce the exterior rotation.
5.4 Optional: Installing the foam cover
A connecting element (such as a connection plate, connection cap or foam
connection cap) provides a detachable connection between the foam cover
and the prosthetic foot.
