Bench Alignment In Alignment Apparatus; Static Alignment Optimisation; Dynamic Alignment Optimisation - Otto Bock Genium X3 Instructions For Use Manual

Preparing the product for use
1) Install the prosthetic foot on the tube adapter and tighten the set screws on the tube adapterto a torque of
15 Nm.
INFORMATION: The printed scale on the tube adapter must face forward.
2) Connect the cable of the tube adapter to the cable of the knee joint.
3) Push the protruding cable loop back into the tube adapter. If the tube adapter has been shortened to the min­
imum length, the plug must be inserted in the cavity. The cable loop must then be stored carefully.
4) Insert the tube adapter about 60 mm into the knee joint (for the exact value, consult the configuration assistant
in the adjustment software).
INFORMATION: Corrections in the insertion depth between 40 mm and 70 mm are permissible (slide
in 10 mm and pull out 20 mm).
5) Turn the foot outwards slightly and slightly tighten the two distal tube clamp screws (approx. 4 Nm).
INFORMATION: After trial fitting, all screws have to be tightened alternately in several steps, increas­
ing the tightening torque slowly until the prescribed tightening torque is reached (section "Technical
data", see page 51).
INFORMATION
Disconnect tube adapter without error message
Five beep and vibration signals are output when the tube adapter is disconnected. In order to avoid this, perform
the following steps while the tube adapter is connected:
► Hold the joint upright and flex the knee head 90°.
► Wait 5 seconds. The joint switches to energy saving mode.
→ The tube adapter can be disconnected without generating a warning signal.

7.1.5 Bench alignment in alignment apparatus

With correct bench alignment, e.g. in the PROS.A. assembly alignment apparatus (743A200), the benefits of the
product are realised to best advantage. If the L.A.S.A.R. assembly alignment apparatus (743L200) is available, it
can be used as well.
Alignment can also be carried out using LaserLine/plumb line.
A calibrated alignment recommendation for prosthesis bench alignment is provided in the adjustment software for
the individual conditions of the prosthesis and patient. Therefore, consult the adjustment software for the alignment
data.
The following points must be observed during alignment:
Static alignment in the alignment apparatus must always be carried out without shoes, otherwise a correct
•
adjustment will not be possible.
Static alignment with the LaserLine/plumb line must be carried out with shoes, otherwise a correct adjust­
•
ment will not be possible.
• Ensure the knee joint is in full extension during bench alignment. To do so, briefly push the socket once into the
fully extended position.

7.1.6 Static alignment optimisation

The adjustment software specifies concrete reference values based on measurement data to help optimise the
alignment.
A precondition is that the alignment recommendations were followed during bench alignment of the prosthesis.
The goal of optimised alignment is that the user must compensate as little as possible with their residual limb.
Optimised alignment of the prosthesis components can reduce the effort required from the patient.
INFORMATION
During static alignment optimisation, the knee joint is automatically locked in the flexion direction. This should
enable the patient to stand in a stable stance that is unaffected by the alignment. Patients can only walk with the
prosthetic leg fully extended in this situation!

7.1.7 Dynamic alignment optimisation

After adjusting the product with the adjustment software, perform dynamic optimisation during trial walking. Often,
the following aspects have to be observed and adapted, if necessary:
• Socket flexion position by verifying step length symmetry (sagittal plane)
• Adduction position of the socket and M-L positioning of the socket adapter (frontal plane)
• Rotation position of the knee joint axis and outward rotation of the prosthetic foot (transversal plane)
