Forbidden positions: 1, 2, 3.
Safe positions: 4, 5, 6, 7, 8, 9, 10, 11, 12.
Reference positions: 4, 5, 6, 7, 8, 9, 10, 11.
Reference positions with safe rotation: 5, 6, 7.
COMMENTS:
Only console transosseous elements can be used in the projection of positions 7,8 and 9.
The application of positions 5,6, and 7 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 ulna while motions in the elbow and in the radiocarpal joints and forearm rotation.
Insertion of transosseous elements in the projection of positions 4,8,9,10 and 11 will limit forearm rotation.
