Anatomy of the Humerus

The video tutorial provides a detailed exploration of the humerus, focusing on its anatomical features. It begins with an overview of the proximal epiphysis, including the head of the humerus and its articulation with the scapula. The tutorial then covers the lesser and greater tubercles, intertubercular sulcus, and deltoid tuberosity. The anterior distal humerus is examined, highlighting the coronoid and radial fossae, as well as the medial and lateral condyles. The posterior aspect is explored, focusing on the radial groove and olecranon fossa. Finally, the anatomical and surgical necks of the humerus are discussed.
