创伤性腕三角纤维软骨复合体损伤的诊治进展

Progress in diagnosis and treatment of traumatic injury to triangular fibrocartilage complex

腕三角纤维软骨复合体（TFCC）是远侧尺桡关节（DRuJ）最重要的稳定结构，可起到缓冲腕关节尺侧轴向负荷、稳定和支撑腕骨的作用。TFCC损伤可导致腕关节尺侧疼痛及DRUJ不稳定，以致于患者无法完成一些日常的基本功能活动，严重者可对患者的生活及心理带来较大影响。近年来，随着对TFCC解剖及损伤机理的理解不断更新及腕关节镜技术的快速发展，TFCC损伤的诊治、特别是关节镜下的诊治领域得到了较大进展，显著改善了TFCC的诊治状况。

Triangular fibrocartilage complex （TFCC） plays an important role in maintaining stability of the distal radioulnar joint （DRUJ）, buffering the ulnar carpal axial impaction and holding the proximal carpal bones. Patients with injured TFCC may suffer pain over the ulnar side of the wrist and DRUJ instability. Many of them may have difficulty in undertaking daily activities, leading to even psychological problems. With the development of arthroscopic technology and updated understanding of the mechanisms of TFCC injury, great progress has been made in the diagnosis and treatment of the traumatic injury, especially in the arthroscopy-assisted treatment.
