Позиции запрета:
1, З.
Forbidden positions: 2, 4, 5, 6, 7, 8, 9, 10, 11, 12.
Safe positions: 4, 5, 6, 7, 8, 9, 10, 11, 12.
Reference positions: 6.
COMMENTS:
Only console transosseous elements can be used in the projection of positions 7 and 9.
The application of position 6 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 radioulnar joints, forearm rotation.
Insertion of transosseous elements in the projection of positions 4, 5, 7, 8, 9, 10,11 and 12 will provide free flexion and extension in adjacent to the forearm joints, but will limit forearm rotation.
