PROTEOR AFLEX 2C162 Serie Notice D'utilisation page 7

4. CLINICAL BENEFITS
The device is recommended for:
•
Flexible version: easier-to-wear night-time orthoses, thanks to the ankle mobility. These flexible devices improve the comfort of
severely spastic patients.
•
Reinforced version: walking orthoses, preventing plantar bending of the dropped or spastic foot. Limits varus/valgus movements.
Counteracts low resistance to dorsal bending movements. Excellent torsion and tensile strength, thanks to their Kevlar reinforcement.
•
Reinforced and arched version: At rest, the orthosis is positioned with slight dorsiflexion. In the swing phase of walking, the natural
elasticity of the joints forces it back to dorsiflexion, freeing more space for the step. Excellent torsion and tensile strength, thanks to
their Kevlar reinforcement.
5. ACCESSORIES AND COMPATIBILITIES
The device is compatible with thermoformed polypropylene or polyethylene orthoses.
These joints are sold in the form of kits containing: 2 joints, 2 thermoforming tools, 4 screws, 4 nails, 1 washer and 2 shock absorbing stops.
6. MOUNTING AND FITTING ON THE PATIENT
Position the first forming tool on the outer malleolus, and fasten it with
nails.
The second tool is positioned and fastened opposite the positive face,
with nails.
Plug any spaces between the tool and the positive with plaster filler.
To create the extension shock absorbing stop mount:
Make a block measuring 60 mm x 30 mm x 6 or 8 mm, from the same
material as the orthosis. Mark out its position on the plaster.
Position the clean and hot block (170 - 190°C) on the positive, in order
to obtain a total thickness and width of more than 10 mm, to
accommodate the stop drill holes and chamfer.
Ensure that the block height provides an excess thickness after cutting
of between 20 and 25 mm.
For thermoforming, use polypropylene or polyethylene.
When thermoforming, mark (without drilling) the screw insertion points.
If thermoforming on Plastazote (PE foam), have the tool raised. Perform thermoforming under vacuum.
Leave to cool down.
Reinforced and arched version:
Before taking the orthosis out of the mould, drill a Ø16 hole
(2C162-XX) or Ø13 hole (2C163-XX) to leave a U-shaped
anterior countersink.
Mark out the cutting lines on the orthosis, and cut the plastic, leaving the forming tools in place.
Cut the forming tools in their centre with a fine blade.
Remove the orthosis from the mould, and take off the leftover parts of the tool.
Reinforced and arched version:
Reduce the posterior part according to the amplitude of the desired plantar bending α.
Polish the edges, adhering to the cutting instructions.
Clear the anterior bending zone of the joint (L=16 for 2C162-XX; L= 13 for 2C163-XX).
Round the edges, to prevent damage to the joint.
Other versions:
Polish the edges, adhering to the cutting instructions.
Grip the lower part of the orthosis.
Drill a Ø D mm hole into the excess thickness, over L mm.
Chamfer using a Ø D' bit.
