Otto Bock 1C11 Terion K2 Instructions For Use Manual page 14

Sagittal alignment: Alignment reference line on a–p markings
of the connection cap/footshell (##06611)
Frontal alignment: Alignment reference line on m–l markings of
the connection cap/footshell (##06611)
Connect the prosthetic foot and prosthetic socket using the chosen
adapters. Be sure to follow the adapter instructions for use.
Sagittal alignment:
Determine the centre of the prosthetic socket with the 50:50
gauge. Align the prosthetic socket centrally to the alignment refer­
ence 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.
5.3 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.
5.4 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 plastic protector from the pyramid after completing the
dynamic fitting and the walking exercises.
5.5 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
