Hand: Introduction & Approach to Elbow and Approach to Forearm

Description

In this instructional video, orthopedic surgeon Daniel Osei presents a comprehensive overview of hand and upper extremity anatomy, focusing on the elbow, forearm, and wrist. He begins with an introduction to the bony structures and their functional relevance, using a sawbones model and a cadaver specimen to illustrate key components.



The video covers the elbow's hinge joint capabilities, emphasizing muscles such as the biceps and brachialis that facilitate flexion and extension. Osei carefully navigates through the intricate relationship between muscles, tendons, ligaments, and nerves, underscoring the delicate nature of nerve preservation in surgical settings. He demonstrates an extensive dissection, detailing the anatomy of elbow flexors, extensors, and the radial nerve, important for wrist and finger movement.



Transitioning to the forearm and wrist, he introduces the radius and ulna, along with the carpal bones and their ligaments, explaining their roles in wrist motion and stability. Osei explains conditions that lead to ligament tears, particularly how they impact wrist function, while showcasing the importance of ligaments in maintaining joint stability. Throughout the presentation, he highlights various tendon structures and their functions during movements involving the fingers and hand.



Concluding the lecture, Osei reflects on the complexity and elegance of upper extremity anatomy, emphasizing its critical role in everyday tasks that require dexterity, such as playing instruments and performing push-ups. He expresses hope that the information presented inspires future surgeons in the field of hand surgery.
