The dart thrower's motion is a wrist rotation along an oblique plane from radial extension to ulnar flexion. We report an in-vivo study to confirm the use of the dart thrower's motion during activities of daily living. Global wrist motion in ten volunteers was recorded using a three-dimensional optoelectronic motion capture system, in which digital infra-red cameras track the movement of retro-reflective marker clusters. Global wrist motion has been approximated to the dart thrower's motion when hammering a nail, throwing a ball, drinking from a glass, pouring from a jug and twisting the lid of a jar, but not when combing hair or manipulating buttons. The dart thrower's motion is the plane of global wrist motion used during most activities of daily living. Arthrodesis of the radiocarpal joint instead of the midcarpal joint will allow better wrist function during most activities of daily living by preserving the dart thrower's motion.
掷飞镖者的动作是手腕沿一个倾斜平面从桡侧伸展向尺侧屈曲旋转。我们报告一项活体研究，以证实日常生活活动中掷飞镖者动作的应用情况。使用三维光电动作捕捉系统记录了十名志愿者的全腕关节运动，该系统通过数字红外摄像机追踪反光标记簇的运动。在钉钉子、扔球、从杯子喝水、从水壶倒水以及拧罐子盖子时，全腕关节运动已近似于掷飞镖者的动作，但在梳头或操作纽扣时则不然。掷飞镖者的动作是大多数日常生活活动中所使用的全腕关节运动平面。与腕中关节相比，桡腕关节融合通过保留掷飞镖者的动作，将使大多数日常生活活动期间的腕关节功能更佳。
