Dynamic Trial Fitting; Optimising The Heel Characteristics; Optional: Installing The Foam Cover - Ottobock 1C68 Triton side flex Instrucciones De Uso

• 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.

5.1.4 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, medial­
ise the prosthetic foot. If the medial movement occurs in the second half
of the stance phase, reduce the exterior rotation.
• Remove the adapter cover from the prosthetic foot after completion of
the dynamic trial fitting and gait training exercises.

5.1.4.1 Optimising the heel characteristics

The heel characteristics are optimised by using heel wedges. In case the
heel strike or heel contact is too soft during the mid-stance phase, the heel
can be stiffened by means of a heel wedge.
Two heel wedges are available (transparent=soft, black=hard). Ottobock
recommends starting with the transparent heel wedge.
1) Align the recesses in the heel wedge, in the proximal and posterior dir­
ections.
2) Slide the heel wedge into position between the attachment spring and
heel spring until it engages (see fig. 3).
3) To remove the heel wedge, push it out to the side.

5.2 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.
INFORMATION: The m-l unit of the prosthetic foot in size 21 deforms
the footshell connection zone. Therefore a connection cap cannot be
used for size 21.
