Humerus of a Male Featuring a Proximal Fracture, Anterior View

Description

Presented in anterior orientation, the male humerus is isolated against a clean background, with a proximal fracture line traversing the region of the greater tubercle laterally and the lesser tubercle more anteriorly and medially. The intertubercular (bicipital) groove sits between them on the anterior proximal humerus, leading inferiorly toward the surgical neck, where the shaft begins to narrow. Superiorly, the humeral head is implied just medial to the tubercles, its articular surface directed toward the glenoid, while the proximal metaphysis lies inferior to the fracture plane. Clear. Focused. Fracture morphology in this location maps directly onto rotator cuff mechanics: the supraspinatus and infraspinatus insert on the greater tubercle and tend to displace its fragment posterosuperiorly, while subscapularis traction on the lesser tubercle can pull that fragment medially. Surgeons and trainees often use the anterior surface and the bicipital groove as a practical landmark when discussing three-part and four-part proximal humerus fractures, reduction strategy, and the risk of humeral head ischemia in more displaced patterns. Attention to the surgical neck also matters, since associated injury to the axillary nerve and posterior circumflex humeral artery is a common concern during both trauma evaluation and operative exposure. Useful for teaching shoulder and brachium osteology, upper-limb trauma modules, and orthopaedic or emergency medicine publications explaining proximal humerus fracture patterns and expected fragment displacement on an anterior view. It also supports patient-facing educational materials when paired with rotator cuff and biceps tendon anatomy. Anatomical accuracy verified by SciePro's Medical Advisory Board.
