Forbidden positions: 4, 5, 6.
Safe positions: 1, 2, 3, 7, 8, 9, 10, 11, 12.
Reference positions: 1, 2, 3, 8, 9, 10.
Reference positions with safe rotation: 1, 2, 3.
COMMENTS:
Only console transosseous elements can be used in the projection of positions 10,11 and 12.
The application of positions 1, 2 and 3 is optimal at this level, because in this case the transosseous elements will minimally stand in the way of soft tissue displacement relative to the radial bone while motions in the radiocarpal and radioulnar joints.
Insertion of transosseous elements in the projection of positions 8, 9, 10 will limit forearm rotation.
