5 Information for use
Compression therapy usually begins 5 to 7 days after amputation. The
timing is determined by the attending doctor. Compression in the
early phase is important because the greatest change in the residual
limb circumference occurs in the initial weeks after amputation.
Course of compression therapy
The course of compression therapy is determined by the attending
doctor. Initially, the bandaged residual limb is measured and the
appropriate liner is selected. Ottobock recommends wearing the liner
twice daily. Start with a short time and extend this daily.
Proposed wearing time (respectively morning and afternoon)
Day 1: 1 hour
Day 2: 2 hours
Changing the liner size
As the oedema decreases, the liner size has to be adjusted to ensure
continuous compression. The residual limb should therefore be meas­
ured regularly and the values noted. This allows the progress of ther­
apy to be tracked and the timing for the next liner size to be determ­
ined.
6 Use
NOTICE
Mechanical overload
Impaired functionality due to mechanical damage
► Check the product for damage prior to each use.
► Do not use the product if its functionality has been impaired.
► Take any necessary measures (e.g. repair, replacement, inspec­
tion by the manufacturer's customer service, etc.).
6.1 Wound dressing
The wound on the residual limb must not be left exposed. The wound
area has to be fully covered.
Day 3: 3 hours
From day 4 on: 4 hours
► Cover the entire wound area with an unmovable dressing (occlus­
ive dressing, for example).
6.2 Size selection
The compression effect of the liner depends on the chosen size.
Therefore, the liner size should correspond as closely as possible to
the measured residual limb circumference. A shorter wearing time can
make it easier for the patient to get used to the liner if compression is
uncomfortable. A larger liner should be chosen only if it is not pos­
sible to wear the appropriate liner.
1) Measure the residual limb circumference 4 cm proximal of the
residual limb end.
2) Select the liner size that corresponds to the resulting measure­
ment.
If the measurement is between two sizes: Select the smaller
size.
3) Check the fit of the liner. With a larger liner, ensure that the liner
stretches and thereby generates compression.
6.3 Optional: Adapting the liner
The liner may be shortened to adapt to the patient's individual needs.
This may limit the ability to reuse the liner on other patients.
Recommended materials: Conventional straight edge scissors
>
(no serrated scissors)
► INFORMATION: For a transfemoral interim prosthesis, the
end of the liner must always be outside the prosthetic sock­
et.
Trim the liner to the required length and contour. Make sure the
cut edges are smooth so the material does not tear.
6.4 Putting on and taking off the liner
Donning
1) Check the liner for damage.
2) Turn the liner inside-out and place it on the end of the residual
limb.
