The infraspinatus muscle inserts onto the greater tubercle of the humerus.Tendinosis of the rotator cuff is a degenerative (genetic, age or activity related) change that occurs in our rotator cuff tendons over time. Rotator cuff tendinosis is exceptionally common. Although many people with shoulder pain will be found to suffer from tendinosis. Many, many people have tendinosis of the rotator cuff and do not even know it.Massive and retracted tears of the supraspinatus and infraspinatus tendons of the rotator cuff are associated with great pain and disability and may be considered "non-repairable," depending on the extent of injury and the experience of the treating clinician.
