Otto Bock 1G6 Instructions For Use Manual page 14

Observe the adapter instructions for use during adaptation and
installation.
Sagittal alignment:
Determine the centre of the prosthetic socket with the 50:50
gauge.
Align the prosthetic socket centrally to the alignment reference line.
Socket flexion:
Residual limb flexion of the patient + 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.
Foot size [cm]
23 to 27
TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.
5.2.2 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.
5.2.3 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.
5.3 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.
