4H101/4H102 Flexion Stops - Otto Bock Genium X3 Instructions For Use Manual

4 4H101/4H102 Flexion stops

CAUTION
Errors in prosthesis alignment. Errors made during the alignment of the prosthesis can damage the hydraulic
unit of the joint A defective hydraulic unit can lead to joint malfunction up to loss of function due to structural
failure This can cause the patient to fall The hydraulic unit may be destroyed if it comes into contact with the
socket! At maximum flexion, it is essential to maintain a minimum distance of 3 mm (1/8") between the hydraulic
unit and the socket At maximum flexion, the knee joint must be equipped with a flexion stop if contact with the
frame of the knee joint cannot be avoided (voluminous residual limbs)
1
When delivered, the knee joint is equipped with the 4H102 Flexion Stop, which reduces the maximum flexion
angle by 15°, thus preventing contact with the hydraulic unit It is also possible to equip the knee joint with the
smaller 4H101 Flexion Stop, which reduces the flexion angle by 75°
INFORMATION
If no flexion stop is desired, the knee joint can also be used without a flexion stop (the screws are removed to-
gether with the flexion stop) In this case, it must be ensured that the socket and the hydraulic unit do not collide
To switch to the smaller 4H101 Flexion Stop:
1
1 Loosen the screws with the 710H5=1 Screwdriver (Fig 1)
2 Remove the 4H102 Flexion Stop and insert the 4H101 Flexion Stop (Fig 2)
3 Clean the screw thread with a brush Apply Loctite 243 onto the screw thread and tighten the screws (Phillips
Recess size 1) with a dynamometric key with 60 NM
