Скачать или смотреть What Is an Extensor Tendon? | Hand Anatomy Explained by Dr. Colin Hong

Extensor tendons play a major role in hand motion, yet most people don’t know where they are or what they do. In this video, Dr. Colin Hong, a board-certified plastic surgeon in Toronto, explains what extensor tendons are and why they are essential for normal hand and wrist movement.

Extensor tendons sit just beneath the skin and run from your forearm into your fingers, thumb, and wrist. Their primary job is to help you straighten your fingers, extend your wrist, and open your hand. Because these tendons are thin and lie close to the surface of the skin, they are more vulnerable to injury from cuts, lacerations, or trauma.

Understanding the anatomy of extensor tendons is the first step in recognizing how injuries affect hand function and why treatment is often necessary. This video provides a clear and simple explanation for patients, helping them understand the structure and importance of these tendons.
