1 – Handing the Tee Shirt
During the fitting session the special seamless T-shirts are delivered. the
patient is explained the need to wash it once before the final placement of the
brace. It takes about 3 weeks for the regulation of perspiration with an
increased risk of skin allergy during this period.
2 - Fitting directly on the skin
The transparency of the polycarbonate is usually used during the fitting, which
will be done directly on the skin.
3 - Progressive tightening with adhesive tape
The 2 hemi-valves are positioned on the iliac crest and blocked at sub-axillary.
With the aid of an adhesive tape, the two hemi-valves are brought together,
which will press against the trochanter.
The adhesive tape bypasses the patient with the objective of making it grow
according to the principle of the mayonnaise tube. The space between the two
hemi valves will gradually decrease.
When the adhesive tape reaches the upper part, the tightening is resumed.
Similarly, when the tape arrives at the bottom again, the tightening is resumed
and the space between the two hemi-valves decreases again.
Gradually, the child realizes a self-elongation of the trunk.
4 - Trimlines
The orthotist draws trim-lines with a large cut at the chest level.
The lower cut is made 2 cm below the anterior superior iliac spine, which allows
a 90 ° sitting position.
The anterior cut is about 2 cm, knowing during the control, there is usually a
The fitting at the lower part requires a new tightening with inferior
overlapping of about 3 cm.
The postero-inferior cut is normal, but the upper cut is much higher to promote
kyphotisation of the thoracic region.
Vertical posterior cuts are also 2 cm apart. An additional quarter-moon cut is
made at the concavities to facilitate the detorsion sitting or lying down,
especially at the lumbar level. These cuts facilitate the check-up of the brace.
The under axillary cutting is very high. It will take about 3 weeks for the
shoulders to lower as the spine is untwisted, according to the principle of
5 - Adult Trimlines
The cuts will be different in the adult who presents most of the time a thoracic
kyphosis. In this case the postero-superior cut is located at the apex of the
kyphosis. The tip of the shoulder blades will be free, which facilitates the
Laterally the sub-axillary cut is inclined at 20 ° upwards and forwards, what is
the opposite as for a adolescent scoliosis.
