Wrist anatomy and the risks of arthritis

The human wrist is a complex anatomical structure composed of eight small bones that work together to allow for precise movements such as writing, cooking, and typing. This intricate system relies on a delicate balance between bones, muscles, tendons, and ligaments to facilitate rotation, flexion, and shock absorption.

Daily repetitive motions, aging, and injuries can disrupt this balance, leading to various forms of arthritis. Common types include osteoarthritis, caused by the wear and tear of articular surfaces; post-traumatic arthritis, resulting from previous injuries; and rheumatoid arthritis, an autoimmune disease. Such conditions can cause chronic pain, swelling, stiffness, and loss of strength, significantly impacting an individual's quality of life and psychological well-being.
