摘要
目的：观察研究腕关节盘（ 又称腕三角纤维软骨） 的形态及其和周围组织关系。方法：采用２０ 只成人手标本，观察腕关节盘的形态、附着点及和周围骨、软组织结构的关系，对关节盘的附着点作了深入的研究。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。结论：腕关节盘对桡腕关节、桡尺远侧关节稳定性起重要作用，其在尺骨茎突的附着点对尺骨茎突骨折及功能有重要影响。
To investigate the morphological feature of the triangular fibrocrtilage(TFC) of the wrist and its syntopy.Methods:Morphological features and attachment of the TFC were observed on 20 wrists of adult cadavers.Detailed observation was made on the point of attachment and structure of the TFC.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.The integrity of the TFC plays an important role in function of the distal radioulnar joint.Conclusions:The TFC is an important structure for stabilization of the ulnocarpal and distal radioulnar joints.The insertion of the TFC in the ulnar styloid process has clinical influence on fracture the ulnar styloid process.
