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

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.
