FIGURE 2

The bicipital - forearm angle: the angle between the epicondylar axis (distal humerus) and a line connecting the two tuberosities (proximal humerus) representa the torsion of the humerus. Because the ulna is perpendicular to the epicondylar axis, the angle between the ulna and vertical is a measure of humeral retroversion.
