Flexion Stop; Optional: Installing The Foam Cover - Otto Bock Genium Instructions For Use Manual

Verification at maximum flexion
Verification at maximum extension

7.1.9 Flexion stop

The knee joint comes fitted with a flexion stop upon delivery. This reduces the maximum flexion angle by 15°, thus
preventing the socket from coming into contact with the hydraulic unit.
To limit the flexion angle, the knee joint can be equipped with the following flexion stops:
• 4H99 flexion stop (in scope of delivery): Reduction of the maximum flexion angle by 7.5°
• 4H100 flexion stop (already installed): reduction of the maximum flexion angle by 15°
• 4H103 flexion stop (optional accessory): Reduction of the maximum flexion angle by 22.5°
The flexion stop can be removed to increase the flexion angle. In this case, it must be ensured that the socket and
the hydraulic unit do not collide (see Page 76).

7.2 Optional: Installing the foam cover

If a cosmetic foam cover is installed on the knee joint, the inductive charging receiver has to be moved.

If the distance between the socket and hydraulics is not sufficient, the hydraulics
may be damaged. Check the distance as follows:
1) Bring the knee joint with socket to maximum flexion.
2) Check the available distance between the hydraulics and socket. It must be at
least 3 mm.
INFORMATION: If the distance is less, a flexion stop has to be installed or
an existing flexion stop replaced with a larger one. For information on the
flexion stop, see the next section.
If the distance between the socket and sealing sleeve/top edge of the installed pro­
tective cover is not sufficient, the frame may be damaged. Check the distance as fol­
lows:
1) Bring the knee joint with socket to maximum extension.
2) Check the available distance between the sealing sleeve/top edge of the
installed protective cover and socket. It must be at least 5 mm.
Removing the flexion stop
1) Use an appropriate screwdriver to loosen the screws on the flexion stop (left and
right of the piston rod).
2) Use the screwdriver to take the flexion stop out of the joint.
INFORMATION: Do not insert the screws without the flexion stop!
Inserting the flexion stop
1) Insert the flexion stop.
2) Secure the screws with 636K13 thread lock.
3) Insert the screws.
4) Tighten the screws to 0.6 Nm with the 710D17 torque wrench.
