59F with symptoms of impingement to evaluate rotator cuff tear

Is this a Supraspinatus or Infraspinatus tendon tear?
Exaggerated external arm rotation is a bit confusing in the Cor and Sagittal plane.
Does the BLO help?  Click here:Yes, because the BLO is in plane with the long axis of the Infraspinatus, which is an external rotator and  appears taut in the BLO images with the arm in external rotation.
The tear is at the posterior insertion of the Supraspinatus.
