The triangular fibrocartilage complex (TFCC) is a structure made of cartilage and ligaments in the wrist, located on the side of the small finger. The TFCC supports and stabilizes the forearm and wrist, especially during rotation or load bearing. Injury to the TFCC can be a result of trauma, such as falling onto an outstretched hand, or excessive rotation of the wrist but can also be caused by chronic degeneration. Injury to the TFCC most commonly results in pain to the small finger side of the wrist. Moving your wrist from side to side, rotating your forearm, or gripping objects can exacerbate pain. Other common symptoms include swelling, decreased grip strength, or grinding/clicking when moving the wrist.
