• Mark the necessary length on the elbow joint bars both in the above-arm
and forearm areas and shorten the bars. Adjust the length of the bars to
the physiological conditions as necessary. The longer the bar the better
the force transmission. The minimum length of the bars from the axis of
rotation must not be less than 10 cm. Carefully debur the cutting edges.
• To avoid the excessive increase of the forearm, they are counter-sunk
into the foam part. Transfer the contours for this purpose (fig. 14). Re-
move the material from the contour corresponding to the bar thickness.
• Adjust the bars in the above-elbow area to the physiological conditions
by bending using the 711S4 Bending Iron. To prevent the damage of
the mechanism of the 16Y27 Joint Piece with Cable Lock, do not start
bending nearer than from the distal area of the first hole (fig. 15).
• Subsequently attach the bars temporarily once again together with the
forearm foam part to the inner socket. Verify the length relationships and
movement possibilities and carry out necessary adjustments.
• Mark the bar contours on the inner socket (fig. 16). Place a dummy (e.g.
616T3 Thermolyn Trolen), thickness 2 mm, into the marked area.
• Laminate the above-elbow and forearm sockets individually.
• Attach the elbow joint bars. For this purpose, drill at least two holes
(ø 4.5 mm) for each bar into the outside above-elbow socket. Transfer
the hole position on the bars and tap the M4 threads in the bars. Attach
the bars with 503F3 Truss Head Screw (fig. 17).
• Bond the bars for the forearm socket.
CAUTION
Processing the bars. Clamp the bars for drilling holes. Use a sharp
drill. The material must not become discolored. Carefully debur the
cutting edges.
