Rotator interval capsule closure: an arthroscopic technique.

The importance of the rotator interval in glenohumeral instability has become increasingly apparent as anatomic studies have illustrated a significant increase in inferior and posterior translations after sectioning of the coracohumeral and superior glenohumeral ligaments. Limited reports of this lesion exist in the literature, and all such lesions have been treated with open procedures, with good clinical results. This report describes an arthroscopic technique for imbrication of the rotator interval in treating symptomatic defects and laxity in the anterosuperior shoulder capsule.
