目的：本研究的主要目的是测量在体外舟状骨和月状骨的运动在9个不同的变化手腕飞镖投掷运动。另一个目标是确定具体的飞镖投掷运动，最大限度地减少舟状骨和月骨motion.Methods：舟状骨和月骨运动记录在7具尸体前臂在各种组合的手腕飞镖投掷运动所造成的simulator.Results：在手腕屈曲和伸展的舟状骨和月骨运动遵循手腕运动。腕桡、尺偏时，舟状骨相应地屈曲和伸展。在中间的运动舟状骨和月骨移动少至26%的总第三掌骨的运动，并不一定遵循一个平面motion.Conclusions：这些研究结果表明，可能有一个飞镖投掷运动期间，可能有最小的舟状骨和月骨的运动。如果受试者的腕部运动在临床上被限制为这种掷镖运动，那么舟骨和月骨手术后早期手部活动可能是可能的。美国手外科学会版权所有（C）2004。
Purpose: The primary purpose of this study was to measure the in vitro scaphoid and lunate motion during 9 different variations of a wrist dart throw motion. Another goal was to determine the specific dart throw motion that minimized scaphoid and lunate motion.Methods: Scaphoid and lunate motion were recorded in 7 cadaver forearms during various combinations of wrist dart throw motions caused by a simulator.Results: During wrist flexion and extension the scaphoid and lunate motions follow the wrist motion. During wrist radial and ulnar deviation the scaphoid correspondingly flex and extend. During intermediate motions the scaphoid and lunate move as little as 26% of the total third metacarpal motion and do not necessarily follow a planar motion.Conclusions: These findings suggest that there may be a dart throw motion during which there may be minimal scaphoid and lunate motion. If a subject's wrist motion could be clinically restricted to this dart throw motion, early hand mobility might be possible after surgery on the scaphoid and lunate.
