Static Alignment Optimisation; Dynamic Alignment Optimisation; Torque Values Of The Screw Connections; Checking The Socket After Bench Alignment - Otto Bock Genium X3 3B5-2 Instructions For Use Manual

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.

8.1.5 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!

8.1.6 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)

8.1.7 Torque values of the screw connections

CAUTION
Incorrectly secured screws
Falling due to breakage of load-bearing components caused by screw connections coming loose.
► After completing all settings, the set screws in the tube adapter must be secured before they are tightened to
the specified torque.
► The tube clamp screws must not be secured but only tightened to the specified torque.
Using the 710D4 torque wrench, tighten the corresponding screws alternately in several cycles until the specified
torque is reached.

Proximal prosthesis components with threaded connector

8.1.8 Checking the socket after bench alignment

After bench alignment, verify that at maximum extension and maximum flexion the distance from the socket to the
knee joint is not less than the minimum. A collision of the socket with the hydraulics or frame can cause damage to
the knee joint.
