1- Description and functions

The DynaStar foot includes the following main components :

 A carbon fiber blade that allows for energy storage and return, as well as inver-

sion/eversion at forefoot.

 A light alloy f rame that ensures heel strike and transfers the stresses to the

blade.

These two parts are linked by an elastomer axis that provides inversion/eversion

of the foot and a good transfer of weight bearing from the heel to the forefoot.

 A polyurethane cosmetic shell which transmits the mechanical stresses between the shoe and the composite struc-

ture.

 A sock in technical fibers reduces noises and wear due to contact between the cosmetic shell and the structure.

Thanks to these components, the foot has a comfortable and flexible behaviour.

2– Indications, maximum weight and connecting components

The Dynastar foot is designed exclusively for lower limb prostheses. It

is appropriate for patients with low, medium or high activity level whose

weight (carried load inclusive) complies with the following table.

The DynaStar foot is designed for a 10 mm heel height. It includes a

male pyramid that allows for the use of standard connectors available

on the market. Thanks to these connectors, the heel height can be ea-

sily modified f rom 0 to 20 mm.

3– Assembling (without the patient)

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 (fig. 1).

4- Alignment (with the patient): Place the foot so that the load line

goes through the posterior third of the foot (f ig. 2)

Coxo femoral

Knee joint centre

Load line :

≈ 15 mm in front of

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 transf er to the forefoot or if heel support is too flexible, you have to position the foot

behind the socket.

- If heel support seems too hard, or if the foot seems too short during transf er to the forefoot, you have to position the

foot ahead of the socket.
