5.1.2 Trial fitting of the prosthetic socket
Required tools and materials:
>
743L30 LaserLine or a plumb line
> The patient should be standing at the height of the heel without shoes on. He/she should be
standing comfortably with the knees in a normal position.
> Compensate for the distance from the socket to the floor.
1) Check the upright pelvis position and make corrections if necessary.
2) Measure and note down the distance from the end of the socket to the floor.
3) Mark up the position of the residual limb on the socket in the frontal and sagittal planes using
the LaserLine or a plumb line (see fig. 3, see fig. 4). When doing this, draw on frontally from
the middle of the patella down to the end of the residual limb.
5.2 Bench Alignment
5.2.1 Optional: Inserting the spacer plate
Inserting the spacer plate increases the structural height of the prosthetic foot from 43 mm to
52 mm.
Required tools and materials:
>
710D4 Torque Wrench
1) If necessary: Remove the lamination anchor from the concave plate (see fig. 5).
2) Remove the 2 cap screws from the sides of the concave plate (see fig. 6).
3) Loosen the countersunk head screw on the surface of the concave plate (see fig. 7).
4) Lift off the concave plate.
5) Remove the short fine-threaded screw from the counter plate and replace it with the long fine-
threaded screw (see fig. 8).
6) Remove the washer from the short fine-threaded screw and place it on the long fine-threaded
screw with the concave side facing upwards.
7) Put on the concave plate (see fig. 9).
8) INFORMATION: Screw on the screws without tightening.
Screw in the two cap screws and the countersunk head screw fully.
9) First tighten the countersunk head screw (installation torque: 46 Nm)
10) Tighten the two cap screws (installation torque: 6 Nm)
11) Place the spacer plate on the concave plate so that the dowel pin is positioned in the head of
the countersunk head screw.
5.2.2 Installing the lamination anchor
Required tools and materials:
>
710D4 Torque Wrench
1) Position the lamination anchor with the two anchor arms close to each other towards the pos­
terior and carefully place it on the fine-threaded screw.
2) Allow the setting aid for the lamination anchor to click in to the guiding groove on the concave
plate.
3) Tighten the fine-threaded screw (installation torque: 46 Nm)
5.2.3 Installing the prosthetic foot
Required tools and materials:
>
743L200 or 743L300 L.A.S.A.R. Assembly, 711S4* Bending Iron, degreasing cleaner (e.g.
634A3 Acetone), 627B2=19 Monofilament Adhesive Tape (alternatively: 699G30=* Cellacast)
1) Set the prosthetic foot in the alignment apparatus to the heel height.
2) Bring the prosthetic foot into outer rotation and clamp it in the alignment apparatus.
