US supraspinatus partial tear at insertion long axis view

Long-axis ultrasound (US) image of an articular surface partial thickness tear (thick arrow) of the supraspinatus tendon (SS) at its insertion on the greater tuberosity (GT). Due to its far distal location, this particular tear is referred to as a "rim-rent tear". There is also a cortical irregularity on the greater tuberosity (arrow), suggesting this is a chronic tear.
