Abstract:
The wrist joint is a complicated structure composed of many bones and ligaments. Therefore, understanding the anatomy and the biomechanics of the wrist is important in order to administer proper treatment for patients. To easily understand the complicated structure, there were many trials to unite the complicated structure with a simple group such as the carpal row concept and the carpal column concept. Movement and load transfer along the wrist joint occurs with balanced action between carpal bones. To evaluate this static equilibrium, measuring tools such as carpal height ratio are used. When wrist flexion/extension occurs, each carpal row moves synchronously with action of the scaphoid. In contrast with flexion/extension, when wrist radial deviation/ulnar deviation occurs, the proximal carpal row moves in the sagittal plane, instead of the coronal plane. Recently, the dart throwing motion which occurred from the position of dorsiflexion with radial deviation to volar flexion with ulnar deviation is considered the main movement of the wrist joint.
