Mounting The Distal Adapters; Mounting The Prosthetic Knee Joint; Mounting The Proximal Adapters; Preparing The Prosthetic Socket For The Lock Slide - Ottobock Prosedo 3R31 Gebrauchsanweisung

6.2.3 Mounting the distal adapters

CAUTION
Improper assembly of the screw connections
Fall due to breakage or loosening of the screw connections
► Clean the threads before every installation.
► Apply the specified installation torque values.
► Observe the instructions for securing the screw connections and the use of the correct
length.
► Mount the distal adapters of the prosthetic knee joint on the prosthetic foot (see Fig.
page 12).

6.2.4 Mounting the prosthetic knee joint

CAUTION
Incorrect mounting on the tube
Falling due to breakage of load-bearing components
► Do not use the insertion range of the prosthetic knee joint for length compensation.
► CAUTION! Clean the contact surfaces of the prosthetic knee joint and tube using a degreas­
ing cleaning agent compatible with the material.
► Mount the prosthetic knee joint as shown in Fig.

6.2.5 Mounting the proximal adapters

► Mount the proximal adapters as shown in Fig.

6.2.6 Preparing the prosthetic socket for the lock slide

► Prepare the prosthetic socket for mounting the lock slide as shown in Fig.
note the following points:
• Positioning at the optimum height for the patient's hand
• Laying the perlon cable in the prosthetic socket, in a straight line from the prosthetic knee
joint to the lock slide
• Lamination plate secured against rotation in the laminate
• In and out holes for the perlon cable with sufficient spacing from the prosthetic knee joint and
lock slide for reliable lock function
• Plastaband as protection for the thread on the lamination plate while laminating
• Greased perlon cable dummy for making a channel centred in the laminate

6.2.7 Marking the prosthetic socket

► Mark the prosthetic socket as shown in Fig.

6.2.8 Positioning the prosthetic socket

► For positioning the prosthetic socket, note Fig.
low.
Thomas test
► Place the flat hand
► Instruct the recumbent patient
► Bring the residual limb to hip flexion until the hollow back disappears.
► Extend the residual limb slowly by pushing it until the pressure of the spine on the back of
your hand diminishes.
► In this residual limb position, measure angle α of the flexion malposition.
Socket flexion
► Based on angle α, determine the optimum socket flexion β
