Anatomical Neck Of The Humerus In Anterior View

Description

Humeral head and its anatomical neck are centered in this anterior view, with the smooth articular surface transitioning abruptly to the narrow circumferential groove where the fibrous capsule of the glenohumeral joint attaches. Lateral to the neck, the greater tubercle projects as a broad prominence, while the lesser tubercle sits anterior and slightly medial, separated from the greater tubercle by the intertubercular sulcus (bicipital groove). Distal to this boundary, the proximal shaft begins to flare, keeping the anatomical neck distinct from the more inferior surgical neck. Orientation is unambiguous. Anatomical neck fractures are uncommon but clinically high stakes because they lie adjacent to the articular cartilage and the capsular reflection, and they can jeopardize the ascending branch of the anterior circumflex humeral artery and the arcuate artery, raising concern for humeral head osteonecrosis. Distinguishing the anatomical neck from the surgical neck also matters when you interpret shoulder radiographs, classify proximal humerus fractures, or discuss hemiarthroplasty versus fixation in displaced intracapsular patterns. Consistent anterior lighting and a tight crop around the tubercles help emphasize where the capsule attaches and where rotator cuff tendons will relate, even when the tendon footprints are not the focus. Use this illustration in upper limb osteology labs, shoulder and elbow modules for medical or physical therapy curricula, and orthopedic publishing where precise terminology (anatomical neck versus surgical neck, greater versus lesser tubercle) needs to stay consistent across figures. It also fits preoperative education materials that explain fracture location relative to the humeral head and bicipital groove. Anatomical accuracy verified by SciePro's Medical Advisory Board.
