The rotator interval is the triangular space between the anterior supraspinatus and superior subscapularis, containing the biceps long head tendon, coracohumeral ligament, and SGHL. Its contracture in adhesive capsulitis produces the rotator interval fibrosis that limits external rotation and inferior arm elevation. Arthroscopic rotator interval closure (suturing supraspinatus to subscapularis) reduces inferior glenohumeral instability.
Constrains inferior and posterior glenohumeral translation; limits external rotation at 0 degrees abduction; the coracohumeral ligament within this space is the primary restraint to inferior subluxation
Rotator interval closure is performed arthroscopically for inferior and multidirectional instability — suturing the interval reduces the inferior pouch volume and tightens the coracohumeral ligament. Conversely, rotator interval release (opening this space) is one of the first steps in arthroscopic adhesive capsulitis release.
