What is TFCC?
TFCC is a medical term which means triangular fibrocartilage complex that is a combination of ligaments and cartilage structure located in the wrist which holds together the arm bones (the radius and the ulna). It serves as a cushion between the ulna bone and the wrist bones (carpals). The structure also has a stabilising function and is responsible for the smooth movement of the wrist joint and stable rotation of the forearm. A tear of the TFCC can cause swollen wrist, wrist pain, loss of grip strength or a combination of these.
