Thanks to Jeff Lambert and Michael Setton who explained the obvious to me….the arm is so abducted, that I was measuring the interval between the greater tuberosity at a point lateral to / beyond the supraspinatus insertion….
so that has no relevance to tear or attenuation of the cuff.
Doh!

I am confused by this.In the AP externally rotated view which is obtained with the arm in abduction there seems to be marked acromiohumeral interval narrowing (I measure <3mm).
For that reason, I reported probably tear of the superior cuff and recommended MRI.
There is a small, thin linear high grade partial intrasubstance tear at the anterior insertion, with no tendon thinning and no retraction.
I can’t explain this….can you?
