What is the definition or description of: shoulder surgery?

Shoulder surgery: Arthroscopic or open procedures to the glenohumeral joint, acromiolclavicular joint, rotator cuff, glenoid labrum, proximal biceps, or capsular tissues.

Shoulder Procedure: Any intervention that breaks the skin's natural protective barrier against foreign invaders may be technically considered a surgical procedure. Most people think of surgery where an open incision is made but increasingly many complex repairs can now be performed without a large incision (arthroscopy or key hole surgery) http://www.Theshouldercenter.Com/shoulder-surgery.Htm.
