Bones of the Arm, Anterior View

Description

Beginning at the shoulder girdle, the scapula sits superior and posterolateral to the proximal humerus, with the humeral head and greater tubercle oriented laterally in anterior view. Distally, the humeral shaft widens into the medial and lateral epicondyles framing the anterior elbow, where the radius crosses laterally from the capitulum toward the wrist while the ulna remains medial, defining the trochlear hinge. In the forearm, the radius and ulna run parallel toward the carpus, then articulate with the eight carpal bones, five metacarpals, and the proximal, middle, and distal phalanges (two phalanges in the thumb). Joint lines are clearly demarcated. Anterior skeletal views of the upper limb are where many learners first understand the radius as the lateral forearm bone and the ulna as the medial stabilizer, and they make it easier to map bony landmarks to palpable exam findings. The relationship of the distal humerus to the radial head is clinically relevant in radial head subluxation (nursemaid’s elbow) and in assessing elbow alignment after trauma, while the greater tubercle provides the key attachment area for supraspinatus, infraspinatus, and teres minor in rotator cuff pathology. Clear depiction of the wrist and hand rays also supports basic fracture pattern orientation, from scaphoid waist injury to metacarpal neck fractures. Ideal for gross anatomy and osteology teaching materials, this plate also suits orthopedic and sports medicine publishing where consistent anterior orientation helps explain physical exam landmarks, fracture descriptions, and standard radiographic positioning correlations. It fits slide decks on upper limb kinematics, splinting approaches, and introductory surgical anatomy for the shoulder, elbow, and wrist.
