Understanding Triangular Fibrocartilage Complex (TFCC) Tears
What Is The TFCC? The Triangular Fibrocartilage Complex (TFCC) is a collective structure made up of the triangular fibrocartilage disc (TFC), the radioulnar ligaments (RULs), and the ulnocarpal ligaments (UCLs) that cushion and support the carpal bones in the wrist. It is located along the side of the little finger, passing over the carpel bones and connecting to the radius and ulna bones. It stabilizes the wrist at the distal radioulnar joint and enables load transmission while rotating or gripping the wrist. It creates a sturdy yet flexible joint between the ulna and the radius bones towards the wrist end, allowing proper forearm rotation. Since it is made up of elastic ligaments, any excess tension or impact force can cause the TFCC to sprain or tear. Common Causes Of TFCC Tears: TFFC tears are common wrist injuries in people who excessively use their wrists. Typically, falling hard with an outstretched hand and backward wrist is most likely to damage the TFCC ligaments. Gymn...
