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.
Gross anatomy
The combination of the coracohumeral ligament and superior glenohumeral ligament has a complex relationship with the long head of biceps tendon (LHB), acting together to prevent subluxation or anterior dislocation of the LHB.
Boundaries
- anterior: posterior aspect of the subscapularis tendon
- posterior: anterior border of the supraspinatus tendon
- medial: lateral margin of the base of the coracoid process
- roof: the rotator interval capsule, reinforced by:
- coracohumeral ligament
