The supraspinatus (plural supraspinati, from Latin supraspinatus) is a relatively small muscle of the upper back that runs from the supraspinatous fossa superior of the scapula (shoulder blade) to the greater tubercle of the humerus. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder.
Supraspinatus Tendinosis/Tendonitis. Supraspinatus Tendinosis/Tendonitis The supraspinatus muscle originates from the supraspinous fossa of the scapula and inserts into the greater tuberosity of the humerus. It is the most commonly injured rotator cuff muscle. Tendinosis refers to internal tendon degeneration. This occurs because of an imbalance between tendon breakdown and tendon repair. Therefore tendinosis can result from an increase in breakdown, (e.g) overuse/injury, or from a decrease in the healing response. Tendonitis refers to tendon inflammation.
