Right Arthroscopic Repair of Crescent Supraspinatus Tear with Two Suture Anchors
This exhibit depicts an arthroscopic repair of a crescent supraspinatus tear with two suture anchors. 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 two single loaded suture anchors are inserted into the greater tuberosity. Sutures from the anchors are then passed through the tendon and tied to secure the repair.
