The Anterolateral Surface Of The Humerus In Lateral View

Description

Sweeping along the lateral aspect of the arm (brachium), the animation orients the humerus in true lateral view and tracks the anterolateral surface across the shaft. Proximally, the greater tubercle and the surgical neck sit superior to the deltoid tuberosity, while distally the lateral supracondylar ridge leads into the lateral epicondyle and capitulum. As the camera progresses, the gentle anterior convexity of the diaphysis becomes apparent, and the transitions between anterior, lateral, and posterior contours read clearly in motion. Orientation on the humeral shaft is not academic trivia. The anterolateral surface is where the deltoid inserts at the deltoid tuberosity, a key landmark when describing midshaft fractures and when placing lateral plates to avoid impinging on insertional footprint and soft tissue planes. Animated rotation and tracking also clarifies how the radial groove runs posteriorly and obliquely, explaining why a fracture line that appears lateral on one projection can still threaten the radial nerve as it courses from posterior to anterior between the heads of triceps and toward the lateral intermuscular septum. Landmarks matter. Use this sequence in upper-limb gross anatomy labs, orthopedic teaching on humeral shaft fracture patterns and fixation corridors, and figure preparation for textbooks detailing surface anatomy, osteology, or surgical approaches to the lateral humerus. It also supports radiology teaching when correlating plain-film lateral projections with 3D bony anatomy. Anatomical accuracy verified by SciePro's Medical Advisory Board.
