The thumb has a crucial role in the hand due to its position with regard to the fingers. The CMC-1 joint enables an extraordinary range of motion, since its geometry allows for opposition. The former joint may often succumb to osteoarthritis because a great range of motion in combination with large forces, small contact areas, and thorough usage are always present. Joint replacement is challenged by the great range of motion based on the necessary joint stability and the demand for sufficient pain reduction. This review highlights the anatomy of the CMC-1 joint with regard to joint preplacement solutions.
由于拇指相对于手指的位置，它在手部起着至关重要的作用。第一掌腕关节（CMC-1）能实现非凡的活动范围，因为其几何结构允许对掌动作。该关节常常会患上骨关节炎，这是因为总是存在大范围的活动，同时伴有较大的力量、较小的接触面积以及频繁的使用。基于必要的关节稳定性和充分减轻疼痛的需求，大范围的活动给关节置换带来了挑战。本综述着重介绍了第一掌腕关节（CMC-1）在关节置换解决方案方面的解剖结构。
