2 Product description
The Ottobock MyCRO Band is a non-sterile temporary orthosis to aid in the correction of head
shape caused by positioning. The orthosis uses contact and growth zones to guide the growth of
the head. The contact zones define gentle limits for growth, while the growth zones leave space in
areas required for forming the natural head shape. An adaptable closure allows for adjustability
as the child grows. The orthosis is made of thermoplastic material with a soft, washable lining on
the interior.
The orthosis was made based on a 3D-scan. The following scanners are compatible:

3 Indications for use and Contraindications
3.1 Indications for use
Intended for medical purposes for use on children from 3to18months of age, with moderate-to-
severe non-synostotic positional plagiocephaly, including children with plagiocephalic, brachy
cephalic, and scaphocephalic shaped heads by applying mild pressure to prominent regions of a
child’s cranium in order to improve cranial symmetry and/or shape. These devices are also indic
ated for adjunctive use for children from 3to18months of age whose synostosis has been surgic
ally corrected, but who still have moderate-to-severe cranial deformities including plagio
cephalic-, brachycephalic -, and scaphocephalic-shaped heads.
The orthosis must be used in accordance with the indications.
3.2 Contraindications
Not for use on children with pre-surgical craniosynostosis or hydrocephalus.

slip out of place which could cause asphyxiation or trauma to the child’s eyes or skin.
►Explain to the caregiver that they may not continue to use a damaged product and the O&P
professional needs to be contacted in this case.
►The expandable clasp is designed to accommodate the child’s growth; if the clasp reaches
maximum expansion during treatment, a new device may be required. Inform the caregiver to
discontinue use of a product that has reached maximum expansion, or if there are indications
that the child has outgrown the orthosis and to contact the O&P professional for a follow up
appointment.
►Evaluate the child’s skin at frequent intervals for signs of irritation or breakdown. Mild eryth
ema, edema and pressure sores, can be expected during the use of a cranial orthosis.

6 Modification
The orthosis is made from polyamide PA12. Grinders and heat may be used to make small adjust
ments to the orthosis.
NOTICE
Note that the heat during the flaring or grinding may cause permanent discoloration.
Prior to making adjustments, the lining of the orthosis needs to be removed in order to avoid
damage to the material that may be caused by the high temperature of the heat gun.
Heat flaring
•Material properties:
Glass transition temperature : 50°C (122°F), Melting temperature: 175°C (347°F)
•Recommended tools:
Heat gun at medium setting, round metal anvil, driving hammer
1) Heat the inner and outer surfaces of the orthosis with the heat gun until the material becomes
malleable.
→Make sure that orthosis is heated over a large surface area and that the heat is never loc
alized. If the material is overheated it may become discolored.

5
→The surface temperature of the plastic should be heated to between 70°C (158°F) and
95°C (203°F). This process should take approximately 5 to 8 minutes.
2) Reshape the malleable material on the anvil. If necessary, a hammer can be used to apply
pressure.
3) Let the orthosis cool down fully.
Grinding
•Recommended tools:
Sander (The grinding speed should not exceed 1500rpm, or the material may overheat and
melt.)
Abrasive sanding cone
Fine grit sandpaper
1) Once complete, use fine grit sandpaper to smooth the edges.
2) Sand the edge of the orthosis, moving from the inside to the outside of the orthosis.
3) Make sure there are no sharp edges before dispensing the orthosis.
7 Handling
During the first few days, the orthosis is worn for shorter periods of time so the child can become
accustomed to it (see the table below). The orthosis should subsequently be worn all day and all
night (23hours minimum) in order to obtain the best possible results. The orthosis should be
worn with as few interruptions as possible, e.g.removed only for bathing or treatment by a
physiotherapist. Wearing the orthosis can cause increased perspiration during the first two to
three weeks. This is normal and decreases over time.
If treatment is required for other illnesses such as torticollis during therapy with the MyCRO
Band, the orthosis may be removed briefly.
If wearing the orthosis is interrupted for an extended period of time, another familiarisation period
may be required.
If there are problems with the orthosis, the caregiver should make an appointment imme
diately. The caregiver should not wait until the next scheduled appointment. It is import
ant that the orthosis is worn consistently.

INFORMATION
Remove the shipping latch (placed inside of the clasp) prior to fitting the orthosis.
1) Check the following points before putting on the orthosis:
→The child is in a stable position with no interfering objects or items near the head.
→Any lotions or creams being used have been absorbed by the skin.
→The orthosis is in proper condition with no cracks or other damage.
→The lining fits inside the orthosis without wrinkles and projects slightly beyond the hard
edge all around.
12) Using the finger slot, grip elastic band to
detach from clasp (see fig.1).
23) Carefully pull the orthosis apart at the clos
ure (see fig.2).

7
34) Align the orthosis and place it onto the
child’s head (see fig.3).
5) Check the fit of the orthosis:
→The arrowhead on the front should
form a vertical line with the middle of
the nose.
→The ears should sit freely in the open
ings in the orthosis.
→The orthosis must not cover the child's
eyes.
→The orthosis can be turned side to side
by max. 1cm.
→The lining should project beyond the
edge of the orthosis all around and
protect the skin against contact with
the plastic.
6) If the orthosis fits correctly: Hold the
orthosis carefully so it cannot turn and
close the elastic band of the closure. A
gap in the closure is normal and no cause
for concern.
7) Make sure the elastic band fits properly in
the guide of the closure.
8) CAUTION! To avoid injuries, always
open the closure before positioning the
orthosis.
If the orthosis does not fit correctly or
has shifted: Repeat the previous steps.
7.2 Removal
INFORMATION
Redness of the skin after removing the orthosis is not unusual, and should go away within 2
hours.
>Prerequisite: The child is in a stable position with no interfering objects or items near the
head.
1) Open the elastic band of the closure.
2) Carefully pull the orthosis apart at the closure.
3) Take the orthosis off the child’s head.
TIP: Gently massage the child's head with your fingertips after removing the orthosis in order
to promote self-perception.
4) Remove the lining from the orthosis and clean it (see page11). Insert the replacement lining
into the orthosis.
7.3 Changing the lining
The lining is attached to the orthosis with micro-hook. It has to fit inside the orthosis without
wrinkles and must be in contact with the orthosis over the entire surface area.
Removing the lining
1) Detach the folded lining in the neck area.
2) Starting at the closure, detach the lining all around the orthosis.

8
Inserting the lining
41) Roll up the lining into a tight roll (see
fig.4).
52) WARNING! Ensure that the lining is
smooth and securely fastened to the
microhooks, to avoid pressure points
due to bunching of the lining.
Position the lining at the closure of the
orthosis. Carefully unroll the lining, press
ing it into the orthosis without wrinkles (see
fig.5).
3) Ensure that the lining projects slightly bey
ond the hard edge all around.

9
64) In the neck area, fold over the lining to the
outside and press it into place (see fig.6).
7.4 Replacing the elastic band
INFORMATION
The elastic band that holds the closure is intended to last the lifetime of the orthosis. If the elast
ic band needs to be replaced during treatment, use the following instructions.
>Prerequisite: Orthosis is taken off
1) Remove the lining from the orthosis.
2) Inside the orthosis: Carefully, remove the elastic band with a small tool (e.g. an allen key)
