Kinematics of the scaphotrapezio-trapezoidal joint during wrist flexion/extension motion (FEM) and radial/ulnar deviation (RUD) was investigated using a 3-dimensional dynamic motion analysis system. The scaphoid/trapezoid motion was found to be a rotational motion obliquely oriented relative to the sagittal plane of the wrist and described in an ulnoflexion/radial extension motion plane in both FEM and RUD of the wrist. The axis of rotation of the scaphoid/trapezoid motion during both FEM and RUD wrist motions was essentially the same and runs through the radiopalmar aspect of the distal scaphoid and the waist of the capitate. Motion analysis also revealed that the trapezium-trapezoid and trapezoid-capitate joints are essentially immobile. Hence, the scaphotrapezio-trapezoidal motion is considered to be a single degree of freedom that is essentially the same in both FEM and RUD of the wrist.
使用三维动态运动分析系统研究了腕关节屈伸运动（FEM）和桡尺偏斜（RUD）过程中舟月三角关节的运动学。发现舟骨/大多角骨运动是相对于腕关节矢状面倾斜定向的旋转运动，并在腕关节的FEM和RUD中均在尺侧屈曲/桡侧伸展运动平面中描述。在腕关节的FEM和RUD运动过程中，舟骨/大多角骨运动的旋转轴基本相同，穿过舟骨远端的桡掌侧和头状骨的腰部。运动分析还显示，大多角骨-小多角骨关节和小多角骨-头状骨关节基本不活动。因此，舟月三角关节运动被认为是一个单一自由度，在腕关节的FEM和RUD中基本相同。
