Abstract

We demonstrate various patterns of traumatic triangular fibrocartilage complex (TFCC) tears including some atypical that cannot be categorized under Palmer's classification. TFCC traumatic tears in 173 wrists were examined arthroscopically or macroscopically and divided into disk tears (subdivided into four types: slit tear, flap tear, horizontal tear and tear within the distal radioulnar joint) and peripheral tears (subdivided into six types: ulnocarpal ligament tear, dorsal tear, radial tear, ulnar styloid tear, foveal tear and distal radioulnar ligament tear). Combinations of these types were found in 32 wrists. Wrist arthroscopy revealed various traumatic TFCC tears that do not come under Palmer's classification; therefore establishment of a new classification for traumatic TFCC tears seems to be warranted.
