The Triangular Fibrocartilage Complex (TFCC) is a crucial structure in the wrist that provides stability and support to the joint. It consists of a triangular-shaped piece of cartilage and ligaments located on the pinky side of the wrist, between the ulna (one of the forearm bones) and the carpal bones (wrist bones).
A TFCC tear refers to damage or injury to the TFCC structure. This can occur due to various reasons, including trauma (such as a fall on an outstretched hand), repetitive wrist movements, or the natural aging process. TFCC tears can range from minor fraying to complete ruptures.
