5.2 Information on Using a Cosmetic Cover
CAUTION
Use of talcum
Falling, damage to the prosthetic knee joint due to lack of lubrication
► Do not use talcum on the prosthetic knee joint or other prosthetic components.
► Only use the foam cover approved by the manufacturer (see section "Combination Possibilit­
ies" – see Page 20).
► To reduce friction and to eliminate noise, apply 519L5 Silicone Spray directly onto the contact
surfaces of the cosmetic foam cover.
► After fabricating the cosmetic cover, repeat the dynamic trial fitting since the cover affects the
adjustments of the prosthesis (e.g. damping).
5.3 Bench Alignment
+ = anterior placement / – = posterior placement (in relation to the alignment reference line)
Item see fig. 7
Required equipment:
Alignment apparatus (e.g., 743L200 L.A.S.A.R. Assembly or 743A200 PROS.A. Assembly),
743A80 50:50 Gauge, 743S12 Heel Height Measuring Apparatus
Position the prosthetic foot in the alignment apparatus in accordance with the following values:
Heel height:
effective heel height (x) + 5 mm
a–p positioning, middle of the prosthetic foot to the sagittal alignment reference line
+30 mm
Exterior foot rotation:
approx. 7°
m–l positioning, middle of the prosthetic foot to the frontal alignment reference line
0 mm medial
Check the prosthetic knee joint according to the section "Checking the Factory Settings" (see
Page 29).
Position the alignment reference point
the alignment apparatus according to the following values:
Height of the alignment reference point in the alignment apparatus:
MTP-floor measurement + 20 mm
a–p positioning of the alignment reference point to the alignment reference line:
0 mm
m–l positioning, centre of the prosthetic knee joint to the frontal alignment reference line
0 mm
External rotation of the prosthetic knee joint:
approx. 5°
INFORMATION: If the length-adjustable 2R45=S Tube Adapter (max. body weight 100 kg)
is used in the alignment of the test prosthesis, the required length for the definitive pros­
thesis is easier to determine.
When using the included tube adapter, note the section "Adapting the Length of the Tube
Adapter" (see Page 25).
Connect the prosthetic knee joint to the prosthetic foot and chosen adapters according to their
instructions for use and the section "Installing the Tube Adapter" (see Page 25).
Position the 743A80 50:50 Gauge on the lateral side of the prosthetic socket and mark a point
respectively in the distal and proximal area.
Using these points, mark the lateral centre line of the prosthetic socket.
Mark the tuberosity height as the tuberosity reference point
