Probe placement supraspinatus long axis view

To image the supraspinatus tendon in long-axis, the ultrasound (US) transducer is first placed in long-axis over the long head of the biceps brachii tendon as it enters the proximal aspect of the intertubercular groove. The US transducer is glided posteriorly to image the supraspinatus tendon insertion on the superior (anterior fibers) and middle (posterior fibers, overlap region with the infraspinatus) facets of the greater tuberosity.
