title: Concepts governing the rotational shift of the intercalated segment of the carpus.
abstract: A model of wrist functions, defining the roles of the ligaments and joint contact surfaces, is presented. The complex patterns of wrist deformity following ligamentous injury are simplified by the understanding of this kinematic model. It is proposed that the basis for surgical correction of wrist injuries should be an understanding of wrist mechanics.
