Figure 4

A 6.5 mm chord was drawn (in a lateral direction) from the medial part of the insertion on the humeral head to the lateral part of the tuberculum major. This fixed point (end of the line at the lateral part of the insertion) was used to draw a 23 mm (7.7×3) horizontal line in a medial direction ensuring agreement of measuring area.
