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