A TFCC tear is an injury to the triangular fibrocartilage complex, found in the wrist, between the end of the ulna bone and the carpals. Its function is to stabilize the radioulnar joint.
The specific structures most often torn in TFCC tears are the meniscal homologue and articular disc (2). This is usually caused by forced or over extension (hyperextension) and pronation of the wrist which is the position most often assumed when falling onto an outstretched arm (3,4, 6).
