► Remove the protective film before the patient leaves the fitting area.
+ = anterior placement / – = posterior placement (in relation to the alignment reference line)
Item
see fig. 5
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 27).
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 tube adapter, note the section "Adapting the Length of the Tube Adapter" (see
Page 24).
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 24).
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
Clearly mark the lateral socket reference point
point.
Position the tuberosity reference point
floor measurement.
CAUTION! The correct position and flexion of the prosthetic socket is crucial for the
safety of the patient and functionality of the prosthetic knee joint, and avoids premature
wear.
INFORMATION: The 4R118 Adapter Plate (max. body weight 125 kg) can be used for fur
ther posterior placement.
Position the prosthetic socket so the lateral socket reference point
reference line
Adjust the socket flexion angle β depending on the hip flexion contracture (angle α) according to
the following specifications:
If the angle α = 0°, the optimum value of the angle β = 3 to 5° to the alignment reference line.
If the angle α > 0°, the optimum value of the angle β = α + 5 to 10°.
