Forbidden positions: 2, 3, 4.

Safe positions: 1, 5, 6, 7, 8, 9, 10, 11, 12.

Reference positions: 5, 6, 7, 8, 9, 10, 11, 12.

COMMENTS:

Only console transosseous elements can be used in the projection of positions 8, 9 and 10.
The application of position 5, 6, 7, 8, 9, 10, 11 and 12 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 elbow and in the radiocarpal joints.
 

   

 

The transosseous elements recommended for use at the radial level IV can be designated as: (IV,5); (IV,5-11); IV,6(IV,6); IV,6-12(IV,6-12); (IV,7); (IV,8); (IV,9); (IV,10); (IV,11); (IV,12) and (IV,12)IV,12.
