Otto Bock 1S49 SACH Instructions For Use Manual page 17

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 setup of the prosthesis in the frontal plane and the sagittal
plane (e.g. by making angle or slide adjustments) so that correct heel
contact and optimal roll-over are ensured.
TT fittings:Make sure that physiological knee movement is achieved
•
after the heel makes impact and the leg begins to bear weight.
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.
Required materials: Degreasing cleaner (e.g. 634A58 isopropyl alco­
>
hol), 636N9 contact adhesive or 636W17 plastic adhesive with 636W26
cross-linking agent
1) Measure the distance from the knee rotation point to the desired end of
the foam cover and add the compression allowance: For PE foam
10 mm, for PUR soft foam 30 mm. For TF prostheses, add twice the
compression allowance.
2) Cut the pre-shaped foam block to length.
3) Pull the foam cover over the prosthesis.
