The Anatomical Neck Of The Humerus In Anterior View

Description

Centered in an anterior view of the proximal humerus, the spherical head sits medial and slightly superior, while the greater tubercle lies lateral and the lesser tubercle projects anteriorly, separated by the intertubercular (bicipital) groove. The anatomical neck forms a subtle circumferential constriction immediately distal to the articular surface, curving toward the tubercles and defining the junction between the head and metaphysis. As the animation progresses, the camera gently tracks and rotates to keep the neck in profile, letting you appreciate how its contour differs from the more distal surgical neck. Orientation stays consistent. That distinction matters in fracture pattern recognition and surgical planning around the shoulder. Proximal humerus fractures occur more often at the surgical neck, but the anatomical neck is clinically tied to head-splitting injuries and to the vascular risk zone for the humeral head supplied primarily by the anterior circumflex humeral artery via the arcuate artery. By moving through slight changes in angle rather than locking to a single frame, the sequence clarifies where the capsular attachment approaches the anatomical neck and why this border can be difficult to identify on plain radiographs. Use it in gross anatomy teaching to anchor terminology (head, anatomical neck, tubercles, intertubercular groove) before introducing rotator cuff insertions and the biceps long head tendon course. It also fits orthopedic education modules on proximal humerus fracture classification, preoperative templating, and radiology primers that correlate an anterior bony view with AP shoulder projections.
