1- Description and functions
Dyna C foot includes three main component. Two composite parts: a C-form malleolus
that allow energy storage and retirn, and a sole providing flexibility on the side, wich en-
sure adaptation to the ground. A polyurethane cosmetic shell which transfer the mecani-
cal stresses between the ground or the shoe and the composite structure. Thanks to
these components, the foot behaviour is flexible and dynamic.
For patients who are active, or very active (children for exampl e), or reach the weight
and activity limits of the module selection guide, a stop can be used to limit warping of
the C-malleolus. This stop comes with the foot and must be installed by the prothesist.
2- Spécification
Dyna C foot is designed exclusively for lower limb prostheses. It is
appropriate for active patients up to 125kg, or very active patients
up to 105kg.
Dyna C foot is designed for a 10mm helle. It include a male pyra-
mid that allow for the use of standard connectors available on the
market. Thanks to these connectors, the heel height can be easily
modified from 0 to 20mm
3- Montage (sans le patient)
A) Gluing of the stop (if necessary):
Remove the foot from its cosmetic
shell, th »en take the sock off. De-
grease the faces that will be glued, let
them dry, then apply epoxy glue on
boyh faces
B) Assembling: Place under the foot a wedge of the same height as the shoe
heel. Fix the female pyramid connector to the foot taking care that its axis be
perpendicular to the ground (fig1).
4- Alignment (with the patient):
Place the foot so that the load line goes through the posterior third of the foot (fig. 2).

the pyramid axis
Notes:
- Increasing equinus provides a more dynamic alignment. It increases energy return at step completion
- If the foot seems too long during transfer to the forefoot or if the heel support is too flexilble, you have to position the
foot behind the socket.
- If heel support seems too hard, or if the foot seems too short during transfer to the forefoot, you have to position the
foot ahead the socket.

Put the stop in contact with the
nut(1), then position it by
pushing it upwards (2) and
toward the nut (3). Let the
glue dry, then put the sock and
the cosmetic shell again.
