Fractured Humerus, Anterior View

Description

Anteriorly, the proximal humerus is centered with the humeral head seated against the glenoid cavity of the scapula, and the fracture line is carried through the anatomical neck immediately distal to the articular surface. Lateral to the head, the greater tubercle sits more laterally, while the lesser tubercle and intertubercular sulcus lie anteriorly, marking the transition toward the diaphysis of the brachium. Distally, the shaft tracks inferiorly toward the elbow, where the trochlea and capitulum align with the ulna and radius, respectively, in an anatomic anterior relationship. Surrounding soft tissues are rendered translucently, allowing the humerus to read clearly under the contour of the shoulder and arm. An anatomical neck fracture is an intracapsular injury, so the clinical conversation shifts from simple alignment to perfusion of the humeral head and the stability of the glenohumeral joint. Blood supply via the anterior and posterior circumflex humeral arteries (with contribution from the arcuate artery) is at risk, and this view helps distinguish an anatomical neck pattern from the more common surgical neck fracture that endangers the axillary nerve. Expect a different management pathway. It is also a useful teaching contrast with anterior shoulder dislocation, where the humeral head migrates anteroinferiorly rather than separating at the neck. Orthopedic texts and exam prep modules use this anterior perspective to anchor classifications of proximal humerus fractures, correlate fracture location with neurovascular risk, and explain why internal fixation versus arthroplasty decisions hinge on head viability. Anatomy and radiography courses can pair it with AP shoulder radiographs to reinforce landmarks, including the tubercles, bicipital groove, and elbow articular contours.
