Nine compounds were isolated from ethanolic extracts of Tadehagi triquetrum ( L. ) Four compounds were isolated from root extracts of Pteris multifida .
Methods : Retrospectively analysed of 200 cases of carpal joint injury . Among them , there were 30 cases of fracture of the os triquetrum .
方法：回顾分析了腕关节损伤资料200份，其中三角骨骨折30例。
The internal fixation instruments for four-corner arthrodesis can be designed according to the data of measurement and the anatomical characteristics of capitatum , lunare , triquetrum and hamate .
依据测量数据及头状骨、月骨、三角骨和钩骨的解剖特点进行设计，可设计适于腕骨四角融合术的内固定器械；
In wrist radial and ulnar deviation , the motions of scaphoid and lunate are similar , the triquetrum has more motion than the scaphoid and lunate .
