4 Material and construction

The 50S1 dynamic ankle orthosis consists of polypropylene and is ready for immediate trial fit-
ting. An elastic strap runs medially from the lateral foot edge to the calf and across the top of the
foot. The torsion cut at the distal end of the brace leaves the ball of the big toe free, thus lifting
the lateral forefoot section.
5 Trial fitting, application and delivery of the orthosis
Apply the orthosis as follows
Place the foot in the plastic shell, sliding the heel to the back.
Pull the lower hook & loop strap from the inner side of the foot across the top of the foot through
the outer plastic guide, then tighten the strap so that the heel will snugly fit to the shell.
Pull the upper hook & loop strap through the plastic loop and fasten it (fig. 1).
Fasten the hook & loop strap on the forefoot.
Slighty stretch the elastic functional strap and fasten it (fig. 2).
Attention!
The orthosis may be worn in the shoe during weight-bearing activities subject to physi-
cian approval. Advise the patient of the risk of slipping when using the orthosis without
shoe – especially on smooth surface. An anti-slip pimple rubber is included and can be
mounted if need be.
Adapting by the orthopedic technician/orthotist
The injection molded polypropylene sheet may be moderately modified (do not heat to temperatures
exceeding 194 °F / 90 °C). If it is necessary to modify the trimlines, the edges must be smoothed
carefully since the material has minimal tear resistance when notched. The supplied straps are
extra long and should be shortened to an appropriate length during fitting.
If pressure develops at the ankle or shin, the pads that are supplied with the orthosis may be
glued to the strap (figs. 3 and 4).
If necessary, you can provide the anti-slip properties by attaching the included pimple rubber in
the heel area of the sole of the orthosis. For this purpose, clean the adhesion surface area with
a fine sanding paper and attach the pimple rubber with double-sided adhesive tape included.
To ensure the effectiveness of this orthosis, it must always be worn snugly.
In addition to proper application and regular check-ups with adjustments, patient co operation
plays an important role. The orthosis must be must worn as prescribed.
Since the orthosis is water-resistent, showers are possible while wearing it.
It is very important that the patient understand the important function of dynamic restraints.
