Several studies have observed how the oblique fibers from both the supraspinatus and the infraspinatus fuse or interdigitate as they converge onto the greater tuberosity1-4. I agree that Figures 5 and 6 may show the supraspinatus insertion area, but perhaps this should be qualified as an anterior supraspinatus-only insertion area; this does not account for the fact that the supraspinatus and infraspinatus interdigitate and obligatorily share insertion site area on the greater tuberosity. At a minimum, this is what is clinically observed; to characterize the insertions as discrete and separate may not be helpful.
