Bench Alignment - Ottobock 3E80 Instrucciones De Uso

3) If the device signals a charging fault, disconnect and then reconnect the charging plug.
4) Disconnect the charging plug before using the prosthesis.
5.2 Alignment
The three-dimensional alignment of the prosthesis components affects the function of the pros­
thesis. The patient can use the prosthesis to its fullest potential only with correct alignment.
Alignment requires the following steps:
• Bench alignment of the prosthesis in the alignment apparatus.
• Static alignment with the patient, to check and correct the alignment of the components.
• Dynamic trial fitting for optimisation and individual adjustment of the prosthesis components.
If necessary, the alignment recommendations (TF modular leg prostheses: 646F219*, TT
•
modular leg prostheses: 646F336*) may be requested from Ottobock.

5.2.1 Bench Alignment

Required tools and materials: 662M4 goniometer, 743S12 heel height measuring
device, 743A80 50:50 gauge, alignment tool (e.g. 743L200 L.A.S.A.R. Assembly or
743A200 PROS.A. Assembly)
Perform the assembly and alignment of the prosthetic components in the alignment
tool according to the following specifications:
a–p positioning, middle of the prosthetic foot to the alignment reference line:
+30 mm
Heel height: Effective heel height (shoe heel height – sole thickness of forefoot)
+ 5 mm
Exterior foot rotation: approx. 5°
Positioning of the alignment reference point (rotation axis of the prosthetic knee joint)
in the alignment apparatus:
MTP-floor measurement + 20 mm
a–p positioning of the alignment reference point to the alignment reference line:
0 mm
External rotation of the prosthetic knee joint:
approx. 5°
Prepare the tube adapter. Observe the adapter instructions for use during adaptation
and installation.
Clean the tube adapter with a degreasing cleaner and insert it in the prosthetic knee
joint to the stop (see fig. 10). Tighten the cap screw in the clamping (tightening
torque: 10 Nm) (see fig. 11).
Join the prosthetic foot with the prosthetic knee joint using the tube adapter.
Mark 2 centre points laterally on the prosthetic socket:
1. At the level of the greater trochanter
2. In the distal region
Join the two points with a line.
Position the prosthetic socket so its proximal point lies on the alignment reference line.
Socket flexion: Individual residual limb flexion + 5°
Join the prosthetic socket and the prosthetic knee joint using the adapters selected.
Be sure to follow the adapter instructions for use during adjustment and installation.
