+ = anterior placement / – = posterior placement (to the alignment reference line)
Item see fig. 4
Exterior foot rotation:
approx. 5°
Structural height of the prosthetic knee joint at the alignment refer
ence point (rotation axis of the prosthetic knee joint):
MTP-floor measurement + 20 mm
a–p positioning of the alignment reference point to the alignment
reference line:
0 mm
Exterior rotation of the prosthetic knee joint:
approx. 5°
Join the prosthetic foot and the prosthetic knee joint with the help
of the foot adapter (for TF trial prosthesis: 4R206; for TF sport
prosthesis: 4R204) and the socket adapter.
The socket adapter can be positioned on the foot adapter in three
positions in the a-p direction. The exterior anterior position is
recommended for advanced users, the exterior posterior position
for beginners.
Observe the adapter instructions for use during adaptation and
installation.
Additional adapters (double adapter, socket adapter) can also be
used for height adjustment (see the section "Combination Possibil
ities" – see Page 21).
Mark 2 centre points laterally on the prosthetic socket:
1. At the level of the trochanter major
2. In the distal region
Join the two points with a line.
Join the prosthetic socket and the prosthetic knee joint with the
help of the lamination anchor.
Observe the lamination anchor instructions for use during adapta
tion and installation.
Positioning of the prosthetic socket to the alignment reference line:
a‑p position: 0 mm (proximal point of the prosthetic sock
•
et)
Socket flexion: hip flexion contracture (determined with
•
Thomas test) + at least 4°
Take the individual situation of the patient into account.
