The greater tubercle of the humerus is a bony projection of the lateral part of the proximal end of the humerus. It is situated lateral to the head of the humerus, and posterolateral to the lesser tubercle of humerus. The greater tubercle is the most lateral bony point of the humerus and is palpable at the posterolateral aspect of the shoulder.

Rotator cuff tendinosis is a very common cause of shoulder pain in the adult population. By definition, rotator cuff tendinosis means that your rotator cuff tendons are starting to show their age. In other words, the rotator cuff is starting to degenerate or wear out. Most rotator cuff tears are due to this degeneration or wearing out of your rotator cuff tissue.
