Radial Side Tear of the Triangular Fibrocartilage Complex



Distal radius fracture induces various soft tissue disruptions. Radial tear of the triangular fibrocartilage complex (TFCC) is a typical soft tissue injury associated with the distal radius fracture. The radial tear of the TFCC includes fibrocartilage central tear and dorsal or palmar rim tear; the latter two may induce distal radioulnar joint (DRUJ) instability [3]. Intrafibro­cartilage tear of the TFC may not be associated with DRUJ instability. When the DRUJ indicates severe instability in the radial tear of the TFCC, the rim area must be repaired, as opposed to the tear inside the fibrocartilage area which just needs arthroscopic partial resection.
