The relative motion of selected carpal bones and the radius was studied using five cadaver specimens labeled with metal markers to precisely quantitate their motions. Data was obtained by means of a combination of orthoradiography, sonic digitization, and computer analysis. We conclude that the wrist functions as two carpal rows with the distal row bones relatively tightly bound to one another and the proximal row bones less so but still moving together. Therefore, we theorize that the proximal row functions as a variable geometry intercalated segment between the distal row and the radius-triangular fibrocartilage.
使用五个标记有金属标志物的尸体标本研究了选定腕骨与桡骨的相对运动，以精确量化它们的运动。通过正位放射摄影、超声数字化和计算机分析相结合的方法获取数据。我们得出结论，腕关节的功能如同两排腕骨，远排腕骨彼此相对紧密相连，近排腕骨之间的连接相对较松，但仍一起运动。因此，我们推测近排腕骨在远排腕骨与桡骨-三角纤维软骨之间起到可变几何形状的插入节段的作用。
