Right Arthroscopic Repair of Rotator Interval Laxity
This exhibit depicts arthroscopic capsular plication to repair rotator interval laxity in the shoulder. The rotator interval is a triangular area of ligamentous structures that provide static support to the shoulder joint. The triangle is created by the interposition of the coracoid process protruding between the inferior edge of the supraspinatus and the superior edge of the subscapularis. Laxity of the rotator interval ligaments can cause multidirectional instability of the glenohumeral joint, increasing the frequency of shoulder subluxation. Arthroscopy is performed and fibrotic tissues are debrided to free the rotator interval. Two sutures are passed through the superior and middle glenohumeral ligaments, spanning across the rotator interval. The ligamentous redundancy is overlapped to reduce capsular laxity. The sutures are then tied to secure the repair.
