Otto Bock 7E8, Instructions For Use Manual

Page: 23 / 92

► In the frontal plane, check the course of the load line relative to
the marked points (prosthetic foot, prosthetic knee joint, spina ili­
aca anterior superior) and correct if needed (see Figure
8
on
page 9).
7.4 Optimising during dynamic trial fitting
CAUTION
Adjusting the Settings
Fall due to incorrect or unfamiliar settings
► Only adapt the settings to the patient gradually.
► Explain the effects of the adjustments on the use of the prosthes­
is to the patient.
Setting the hip extensor
► Set the hip extensor according to Figure
9
on page 10 in such a
way that hip extension is always achieved while walking, while
ensuring it does not knock against the stop too hard (
increas­
ing spring pre-tensioning, reducing spring pre-tensioning).
Fine-tuning the settings
► The various settings of the prosthesis cannot be adjusted entirely
independently of each other. If the settings cannot be fully adjus­
ted to the comfort needs of the patient, the settings should be
established primarily based on safety aspects.
► Adapt the settings of the prosthetic components to the patient by
means of fine-tuning and exercises.
► Check the adjustment of the prosthesis settings during normal
consultations and the annual safety inspection.
Advise the patient to check the prosthesis if changes in function
occur.

7.5 Attaching the cosmetic cover
CAUTION
Use of highly hygroscopic particles (grease-absorbent sub­
stances such as talcum)
Risk of injury, damage to the product due to lack of lubrication
► Do not allow the product to come into contact with highly hygro­
scopic particles.
► To reduce friction and to eliminate noise, apply 519L5 Silicone
Spray directly onto the contact surfaces of the cosmetic foam cov­
er.
► After affixing the cosmetic elements, verify proper functioning of
the prosthesis.
7.6 Finishing the prosthesis
►
CAUTION!
To avoid product damage and the risk of falling, finish
the prosthesis by replacing set screws that are too short or too
long, and by tightening all screw connections. In doing so, note
the instructions for use for all prosthesis components regarding
torque values and thread lock.
Securing the abduction/adduction position (
10
on page 11)
► Secure the abduction/adduction position as shown in the illustra­
tion:
→ : Mark the position of the prosthetic hip joint
→ : Use the 7Z68 drilling template
→ : Bore through
→ : Tighten the set screw
