Greg is somewhat of a "weekend athlete" who has overextended himself by pitching multiple baseball games for a local team during the week and by playing golf on the weekends for several hours
He presented himself to the emergency room last week with severe shoulder pain (at the glenohumeral joint). The physician told him that the X-ray was not conclusive, but he may have damage to his rotator cuff. What is the rotator cuff, and how might he have caused this damage? What remedies will the physician recommend?
What will be an ideal response
Greg has either stretched or torn his rotator cuff. He will be told to rest for a few months, and if the pain does not subside, surgery will be necessary. The rotator cuff is made up of four tendons that belong to the subscapularis, supraspinatus, infraspinatus, and teres minor muscles and encircle the shoulder joint. They are vulnerable to damage when the arm is circumducted vigorously. Greg is obviously overdoing his activities by pitching multiple baseball games per week and playing golf on weekends.
