A TFCC tear is a tear in the triangular fibrocartilage complex, a structure found in the little finger side of the wrist. Within the forearm are 2 bones, the radius (thumb side) and the ulna (little finger side), and within the wrist there are 8 wrist bones (carpals). The TFCC sits between the ulna and 2 carpal bones, the triquetrum and lunate.
