Dynamic Alignment Optimisation; Torque Values Of The Screw Connections - Otto Bock Kenevo 3C60 Instructions For Use Manual

Preparation for Use

7.1.5 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)

7.1.6 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 screws in the clamp bracket 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.
Screw connection
Tube adapter on prosthetic foot
Clamp bracket on knee joint
Fitting for short residual limb
Rotation adapter or sliding adapter
Fitting for long residual limb

To determine the load line, have the patient (with shoes) stand on
the force measuring plate with the prosthetic side and on the
height compensation plate with the other leg.
The prosthesis side must be sufficiently loaded (>35% body
weight). Note the weight display on the L.A.S.A.R. Posture.
Optimise the alignment solely by changing the plantar flexion.
Only make adjustments to the distal and proximal setscrews of
the socket adapter on the prosthetic foot, so that the load line
(laser line) runs approx. 30 mm/1.18 inch in front of the align­
ment reference point (= knee axis) for the knee joint.
