TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.
5.1.3 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.
5.1.4 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.
• Remove the adapter cover from the prosthetic foot after completion of
the dynamic trial fitting and gait training exercises.
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.
Required materials: Degreasing cleaner (e.g. 634A58 isopropyl alco­
>
hol), 636N9 contact adhesive or 636W17 plastic adhesive
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.
4) Set the connecting element onto the footshell or prosthetic foot. Depend­
ing on the version, the connecting element engages in the edge or sits
on the foot adapter.
5) Mount the prosthetic foot on the prosthesis.
6) Mark the outer contour of the connecting element on the distal face of
the foam cover.
7) Dismount the prosthetic foot and remove the connecting element.
8) Clean the connecting element using a degreasing cleaner.
9) Glue the connecting element onto the distal face of the foam cover
according to the marked outer contour.
10) Let the glue dry (approx. 10 minutes).
