Note: In this image, the patient’s shoulder is internally rotated.

1. Posterior Deltoid Muscle
2. Infraspinatus Tendon
3. Spinoglenoid Notch/Groove
4. Posterior Glenoid
5. Joint Capsule
6. Posterior Labrum
7. Humeral Head

1. Lateral Deltoid Muscle
2. Supraspinatus Tendon
3. Humeral Head
4. Piribursal Fat
5. Subacromial/Subdeltoid Bursa
6. Subscapularis Tendon
7. Coracohumeral Ligament (CHL)
8. Superior Glenohumeral Ligament (SGHL)

1. Deltoid Muscle
2. Supraspinatus Tendon
3. Greater Tuberosity
4. Articular Hyaline Cartilage

Asterisk: Bursa

1. Greater Tuberosity Middle Facet
2. Footprint of Infraspinatus/Supraspinatus

Anterior Greater Tuberosity

1. Greater Tuberosity
2. Humeral Head
3. Supraspinatus Tendon

Anterior over biceps tendon at the level of the humeral head

1. Biceps tendon (longitudinal) as it emerges from its origin in the glenohumeral joint to enter the rotator cuff interval

1. Surface of Humeral Head
2. Greater Tuberosity (where it begins a footprint)
3. The Most Distal Greater Tuberosity (facet profiles)

1. Anterior Facet (Supraspinatus Insertion)
2. Middle Facet (Interdigitated Supraspinatus-Infraspinatus Insertion)—this combined insertion stretches from the anterior part of the greater tuberosity, where most of the fibers are from the supraspinatus, to the posterior part of the middle facet where most of the fibers are from the infraspinatus. In the center of this attachment complex fibers from supraspinatus and from infraspinatus interdigitate, and the tendons cannot be distinguished.
3. Inferior/Posterior Facet (Teres Minor Insertion)
4. Biceps Groove
5. Humeral Head
6. Inferior (Underneath) Surface of the Acromion
