What is a triangular fibrocartilage complex tear?



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.

The triangular fibrocartilage complex is made up of, and connects with a number of structures within the wrist including:
  • articular disc
  • meniscus homologue,
  • ulnar collateral ligament
  • volar/palmer (palm side) & dorsal (back side) radioulnar ligaments,
  • sheath of the extensor carpi ulnaris tendon.
  • ulnolunate and ulnotriquetral ligaments
