Humerus and scapula

This tutorial explores the anatomy of the shoulder joint, focusing on the humerus and scapula. It discusses the portrayal of shoulder dislocations in media versus reality, detailing the structure and function of the humerus and scapula, including their articulations and associated ligaments. The tutorial also covers shoulder dislocation and reduction techniques, emphasizing the Cunningham method. It concludes with a summary of key anatomical features and clinical insights.
