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 triangular fibrocartilage complex (TFCC) is located on the side of the wrist with the bump (the âulnarâ side of the wrist) and is made up of cartilage and ligament support structures. It acts as a shock absorber and stabilises the wrist bones during twisting movements.
