   In this section of atlas is represented the bloc of cuttings of each of the eight principal levels of the forearm relative to the Radius in middle position (between pronation and supination).
Safe positions form 68 % (65 positions) from 96 positions envisaged by goniometric system we use.
Carried out investigations showed, that physiological movements in radioulnar joints (forearm rotation) don't exceed 120°-140°: 65°±5° for supination and pronation. In no one of these series of experiments at the VIII level was found ulna and radius placed strictly in frontal plane. Found position of the radial bone relative to the ulna is reflected in the represented diagrams.
The results of investigations of soft tissue movements relative to the radius while supination and pronation of the forearm gave an opportunity to make a conclusion that application of external fixation of the radius with the safe rotation function is impossible. Insertion of external elements in this context is possible at the VII and VIII levels in the projections of 8 (8%) positions. They are pointed by sign . The reference positions that provide only flexion and extension in the elbow and in the radiocarpal joints (47% from general number of positions) are pointed by sign .
On the forearm there are three Yin-meridians with centrifugal direction of the energy motion pass: lung meridian (P), heart meridian (C) and pericardium meridian (MC). There are three Yang-meridians with centripetal direction of energy motion: large bowel meridian (GI), tripple heater meridian (TR), and small bowel meridian (IG). The meridians on the forearm are represented by 27 active points.
According to the Method of Unified Designation of Transosseous Elements applicated to the radial bone are placed in round brackets.
Notes (VIII,12-6) VIII,12-6 and VIII,6-12(VIII,6-12) designate the same K-wire, inserted at VIII level through both bones. But in the first case the wire is inserted from the side of the radius and in second - from the side of the ulna.
   Separately is represented the block of cuttings with coordinate system relative to the ulna in forearm supination.
