Right Arthroscopic Repair of Supraspinatus Avulsion with a Suture Anchor
This exhibit depicts the arthroscopic repair of a supraspinatus avulsion with a suture anchor. The supraspinatus muscle forms the superior aspect of the rotator cuff. It assists the deltoid in abduction of the arm at the shoulder and stabilizes the glenohumeral joint by resisting downward gravitational force. Of the four rotator cuff muscles, it is most frequently subjected to tearing, particularly at its insertion site on the greater tuberosity of the humerus. Tearing of the supraspinatus tendon can result in shoulder pain, weakness, and impaired abduction. Arthroscopy is performed and the supraspinatus is debrided to a stable edge. The supraspinatus footprint is decorticated, stay sutures are placed in the supraspinatus tendon, and a double loaded suture anchor is impacted into the greater tuberosity. Sutures from the anchor are then passed through the tendon and tied to secure the repair.
