FITTING INSTRUCTIONS

1. Mount the springs on the wrist plate in the middle position, using the
screws. Do not tighten the first screw before inserting the second,
rather, tighten the two screws alternately. Do not overtighten the
screws: they are tight enough when the head is in firm contact with
the plate.
2. Place the covering on the hook and loop tape that is already attached
to the arm plate.
3. Place the wrist plate on the lower arm, directly behind the wrist joint.
Ensure that the styloid process of the ulna is not obstructed(Figure 3).
4. Remove the orthosis entirely from the patient. By gradually heating
the inside of the arm plate with a heat gun to a maximum of 100 °C, it
can be locally modified to match the anatomy of the patient's wrist
and lower arm. Ensure that the plate is not twisted on the arm during
the fitting. A reference point to ensure correct alignment is to check
that the springs are as parallel as possible as they extend to the hand.
The fitting of the wrist plate is important for comfort in use.
5. Now slide the hand plate over the hand as far as the base of the
thumb. The side with the tapered edge should be on the side of the
thumb. Then flex the fingers at an angle of 90°. Now position the
hand plate so that it covers the hand and is comfortable (Figure 4). If
the hand plate needs to be adjusted to the shape of the hand, warm it
gradually from the inside, as indicated above.
6. Now lay the hand, with the hand plate in the correct position, flat on
the table, with the back of the hand upwards. Mark the position of the
small holes on both sides of the hand plate, by drawing through the
holes onto the hand (Figure 5). Then remove the hand plate again.
7. Place the arm plate in the correct position on the lower arm, and lay
the lower arm flat on a table. Position the patient's hand in
approximately 30° extension, and position the springs alongside the
hand, ensuring that the arm plate remains in the correct position.
Make marks on the springs, level with the points marked on the hand
(Figure 6).
8. Remove the surplus part of the outer covering on the springs, by
carefully cutting a notch around it, with a craft knife.
9. Mark both springs 2 centimeters beyond the end of the outer covering
(Figure 7).
10. Shorten the springs at the marked positions. An effective method to
do this is to partially cut the springs, using a 'dremel' (a small
rotating tool) fitted with a grinding disc, and then to break them.
Points to note:
a. Ensure that there is only one cut in the spring. If there is another notch
somewhere on the spring, it cannot be used. There would be a risk of it's
breaking.
b. Remove any sharp edges after cutting.
11. Assemble the whole orthosis and glue the end caps in position.
Note: This requires some force to ensure they are securely in place.
12. Fit the orthosis on the patient and check that it is fitting and
functioning correctly. If necessary the shape can still be modified at
this stage. Lock the screws in position by placing a drop of superglue
on the head of the screw. Remove any excess glue after about 10
seconds. Then affix the required number of hook and loop pieces in
the arm plate so that the covering is properly secure.
13. Finally, check whether the end caps are still firmly glued in place.
