3 Intended use
3.1 Indications for use
The 8E550 Michelangelo Hand Transcarpal is to be used exclusively for upper limb exoprosthet­
ic fittings.
3.2 Conditions of use
The Axon-Bus prosthetic system was developed for everyday use and must not be used for unusu­
al activities. These unusual activities include, for example, sports with excessive strain and/or
shocks to the socket connection (pushups, downhill racing, mountain biking, ...) or extreme
sports (free climbing, paragliding, etc.). Furthermore, the Axon-Bus prosthetic system should not
be used for the operation of motor vehicles, heavy equipment (e.g. construction machines),
industrial machines or motor-driven equipment.
The prosthetic system is intended exclusively for use on one user. Use of the prosthetic system
by another person is not approved by the manufacturer.
Permissible ambient conditions are described in the technical data (see page 31).
3.3 Indications
The 8E550 Michelangelo Hand Transcarpal can be used for unilateral or bilateral amputees from
a transradial to transcarpal amputation level or in the case of dysmelia of the forearm.
Open palm
In the open palm position, the thumb is positioned all the way out; this
allows for a flat hand position with a completely opened thumb position.
The degree of mobility for internal and external rotation of the forearm
depends on the length of the residual limb. A compensatory movement from
the upper arm may be required in order to hold a flat object in a horizontal
position.
INFORMATION: The starting position of the rotation setting can be
adjusted by the O&P professional within a range of ± 15 °.
Opposition Power Grip
The opening width makes it possible to hold cylindrical objects with large
diameters 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 securely fixated with the
thumb in closed position.
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.
