Open palm
In the open palm position, the thumb is positioned all the way out; this achieves a
flat hand position with a completely opened thumb position.
Opposition power grip
The opening width makes it possible to hold cylindrical objects with large diamet
ers and with an open thumb position.
Tripod pinch
Together with the index finger and the middle finger, the thumb forms a three-
point support; small objects can then be fixated with the thumb position closed.
Finger abduction/adduction
By spreading the fingers, a flat, thin object (< 3 mm/< 0.12 inch) can be held
between the fingertips when closing the hand.

The Axon-Bus prosthetic system is to be used exclusively for exoprosthetic fittings of the upper
limbs.

3.3 Conditions of use
The Axon-Bus prosthethic system was developed for everyday use and must not be used for

Permissible ambient conditions are described in the technical data (see Page 41).
