Head Of The Humerus, Anterior View

Description

Humeral head (caput humeri) dominates the proximal end of the arm bone in an anterior view, with the smooth articular surface curving medially and slightly superiorly toward the glenoid cavity of the scapula. Inferior to the head, the anatomical neck forms a subtle circumferential margin, while the greater tubercle sits laterally and the lesser tubercle projects more anteriorly, framing the intertubercular sulcus (bicipital groove) between them. The proximal shaft continues inferiorly toward the surgical neck region, where cortical contour begins to narrow. Orientation reads clearly from front to back. Clinically, this anatomy anchors most discussions of glenohumeral instability: anterior shoulder dislocation typically positions the humeral head anteroinferior to the glenoid, and the relationship of the head to the tubercles helps learners anticipate where associated lesions occur. The proximal humerus is also a common fracture site in older adults, and appreciating the transition from head to neck supports classification and treatment planning, including fixation pathways that must respect the articular surface. Surface continuity matters for arthroplasty. The lighting and smooth shading on the articular cartilage region make it easy to distinguish the spherical head from the rougher tubercular bone where the rotator cuff tendons insert (supraspinatus, infraspinatus, teres minor on the greater tubercle, subscapularis on the lesser tubercle). Use this illustration in upper limb osteology labs, shoulder anatomy lectures, and surgical education materials covering proximal humerus fractures, Bankart and Hill-Sachs correlations, and total shoulder arthroplasty component positioning. It also supports medical publishing diagrams on the skeleton and limb landmarks, where an anterior humerus view helps orient readers before adding the scapula, capsule, or rotator cuff.
