Forbidden positions: 1, 3, 4, 5.

Safe positions: 2, 6, 7, 8, 9, 10, 11, 12.

Reference positions: 2, 8, 9, 10, 11.

COMMENTS:

Only console transosseous elements can be used in the projection of positions 7, 8, 9, 10 and 11.
Close disposition of n.radialis to the humeral bone in the projection of pos.4 and 5 proposes the application in the projection of pos. 10 and 11 of console transosseous elements that perforate only anterolateral cortical plate.
The application of positions 2, 8, 9, 10 and 11 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 humerus while motions in the glenohumeral and (in lesser degree) in the elbow joints.
 

   

 

The transosseous elements recommended for use at the humeral level III can be designated as: III,2; III,8; III,9; III,10; III,11 и III,2-8.
