Forbidden positions: 3, 4, 5.
Safe positions: 1, 2, 6, 7, 8, 9, 10, 11, 12.
Reference positions: 8, 9.
COMMENTS:
Only console transosseous elements can be used in the projection of positions 9,10 and 11.
The application of positions 8 and 9 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 femur while motions in adjacent joints.
