This is an arthroscopic shoulder surgery:
When the patient is appropriately prepped and anesthetized, the provider makes three small incisions in the shoulder area. He inserts the arthroscope through one of the incisions into the shoulder joint. He instills saline solution to expand the area around the shoulder joint. He views the entire shoulder joint area using the camera of the scope. He then inserts additional instruments and performs repairs to the shoulder blade to decompress, or relieve pressure, on structures that rub together abnormally. He removes part of the coracoacromial ligament, if necessary. The provider then irrigates the area, checks for bleeding, removes any instruments, and closes the incisions.
