目的：研究桡骨远端骨折后掌倾角及尺偏角改变对桡腕关节的影响。
Objective: to investigate the impact of tilt changes due to distal radius fractures on wrist joint.
正常中心值显示远端桡尺关节旋转中心从各个方向看均在桡切迹的中半位。
The normal epicenter values indicated that the center of rotation of the distal radioulnar joint fell in the middle half of the sigmoid notch in all positions.
结论：术中必须纠正桡骨远端短缩及桡侧偏斜畸形、下尺桡关节脱位和恢复掌倾角；
Conclusion Madelung deformity , distal radioulnar joint dislocation and the change in palm angles of inclination must be rectified.
结果：研究表明腕关节盘位于腕关节的特殊位置，其尺侧附着于尺骨茎突和尺骨茎突陷窝两部分，并和桡尺远端关节侧副韧带存在密切关系。
Results: the study showed that the TFC located in a very special part of the wrist and had intimate relations with the ulnar styloid process and recess.
