腕关节盘的解剖学研究及临床意义

目的：观察研究腕关节盘的形态及其和周围组织关系。方法：采用２０只成人手标本,观察关节盘的形态,附着点的周围骨、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,其尺侧附着尺骨茎突和尺骨茎突陷窝两部分,并和桡尺远端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。

An anatomical study of triangular fibrocartilage of the wrist and its clinical significance

ObjectiveTo investigate the morphological feature of the triangularfibrocrtilage(TFC) of the wrist and its syntopy.MethodsMorphologicalfeatures and attachment of the TFC were observed on 20 wrists of adult cadavers.Detailedobservation was made on the point of attachment and structure of the TFC.ResultsThestudy showed that the TFC located in a very special part of the wrist and had intimaterelations with the ulnar styloid process and recess.The integrity of the TFC plays animportant role in function of the distal radioulnar joint.ConclusionsTheTFC is an important structure for stabilization of the ulnocarpal and distal radioulnarjoints.The insertion of the TFC in the ulnar styloid process has clinical influence onfracture the ulnar styloid process.
