Patient Instructions
5
If the foot emits any noises, contact a prosthetist as soon as possible to inspect
the foot. This also applies if the foot does not work properly.
Note any change in or loss of function. This includes diminished shock
absorptions or lateral exibility and loss of forward elasticity. Contact your
prosthetist if this occurs, and do not use the product until its function has been
examined.
Remember that it can take up to 14 days to get used to a new foot prosthesis.
Because the foot stimulates a natural pattern of movement, you may
occasionally experience some muscle soreness in the amputated leg when you
begin using it.
If you dramatically gain or lose weight, contact your prosthetist to ensure that
the foot prosthesis ts you.
You should also avoid heavy lifting e.g. heavy rucksacks, as this aects the total
load on the foot. If you often carry heavy loads, it is better to use a foot in a
higher weight class. In this case, talk to your prosthetist about it.

10 Xtend Foot Instructions for Use
Xtend Foot van Lindhe Xtend, distributeur Loth Fabenim B.V.
Installation
Xtend Foot has three dierent laminates that interact during use to reproduce
sucient energy while the foot compensates for uneven surfaces. The pyramid
ensures correct tting on a connecting leg prosthesis/tublar structure. Thread
locker e.g. Loctite 275 is nedded for the installation.
7
WARNING Only trained personnel such as an prosthetist may install, carry
out maintenance on and t the product on prosthetic users.
WARNING Do not remove the pyramid or modify the foot’s construction.
Any modications made to the product will invalidate the product guarantee.

Adjustment
The foot must be adjusted and adapted to
the patient for the greatest possible comfort.
Observe the following tting instructions to
ensure a proper t.
Dynamic adjustment
Place the foot so the vertical goes through the
back third portion of the foot, as seen from
the side.
Seen from the front, place the foot so the
centre of the knee and the center of the
pyramid are in line between the rst and
second toe.
Xtend Foot is exible on uneven surfaces and
requires no extra adjustment for dierent
surfaces. This is managed by the construction
in the foot itself.
8
Static adjustment
The foot prosthesis is designed for a 10 mm high heel. The foot prosthesis must be
tted in the foot shell when tested on the patient. The unit must be either tted in a
shoe or alternatively a heel wedge can be used to adjust the height correctly when
tting. Centre the pyramid straight ahead and tighten the screws.

Fitting the Foot Shell
Careful handling while tting will extend the function and service life of the foot shell
Never use sharp tools such as screwdrivers to t or remove the foot shell. We also
recommend not to t the foot shell when the patient is wearing the foot prosthesis

Do as follows:
Pull the protective sock on over the bre composite foot.
Put the forefoot in the foot shell as far as you can and place a shoe horn
between the end of the heel and inside the foot shell. Assure that the foot shell
is touching the inner bottom surface.
Gently push the heel into position. Make sure the foot ends up straight and in
the appropriate notches on the inside of the foot shell.
Pull away the shoe horn and check that the composite foot’s heel laminate
snaps into the heel lock in the foot shell (See gure A).
Only a Lindhe Xtend foot shell may be used with the bre composite foot.
