Rotator cuff interval

The rotator cuff interval is a triangular space between the tendons of subscapularis and supraspinatus and the base of the coracoid process.

It is roofed by the rotator interval capsule, which is principally made up of the coracohumeral ligament. It contains the tendon of the long head of the biceps and the superior glenohumeral ligament.

The combination of the coracohumeral ligament and superior glenohumeral ligament have a complex relationship to the long head of biceps tendon (LHB), acting together to hold the LHB from subluxing or dislocating anteriorly.

It was first defined by C S Neer in 1970 3
