Otto Bock 3R20 Instructions For Use Manual page 10

► In case of changes in or loss of functionality, do not continue
using the product (see "Signs of changes in or loss of functional­
ity during use" in this section).
► Take any necessary measures (e.g. repair, replacement, inspec­
tion by the manufacturer's customer service, etc.).
Signs of changes in or loss of functionality during use
Changes in functionality can manifest themselves, for example,
through a changed gait (swing phase, stance phase), incomplete
extension, stiffness and the development of noise.

7 Preparing the product for use
7.1 Information on fabrication of a prosthesis
CAUTION
Incorrect alignment, assembly or adjustment
Injury due to incorrectly installed or adjusted as well as damaged
prosthetic components
► Observe the alignment, assembly and adjustment instructions.
CAUTION
Initial use of the prosthesis by the patient
Fall due to lack of patient experience, incorrect alignment or incor­
rect adjustment of the prosthesis
► For the safety of the patient, use a suitable device (e.g. parallel
bars, handrail, wheeled walker) during initial standing and walk­
ing.

7.2 Bench alignment of the prosthesis
CAUTION
Improper assembly of the screw connections
Risk of injury due to breakage or loosening of the screw connec­
tions
► Clean the threads before every installation.
► Apply the specified torque values.
► Follow the instructions regarding the length of the screws and
about how to secure the screws.
INFORMATION
The prosthetic components and prosthesis shown in the illustrations
are used as examples to illustrate the general process. The instruc­
tions for use of the prosthetic components selected for the patient
contain detailed information and have to be used for fabrication of
the prosthesis.
► To enable the patient to stand safely, align the prosthesis using
the alignment images (Figure
instructions for use of all prosthesis components used.
► Additionally, observe Figure
points for the bench alignment of the prosthesis:
► Turn the adjustable extension stop to the right to the maximum
extension position for bench alignment.
► Use the rotation to the left shown in
patient has difficulty initiating the flexion. Note that this reduces
the stability of the prosthetic joint.
7.3 Optimising the static alignment
► Check and optimise static alignment on standing patient (see
5
Fig. on page 4).
► If a measuring device for representing load lines is available,
check the distances indicated in Figure
the prosthesis alignment as necessary.
