What is TFCC Injury?

The triangular fibrocartilage complex (TFCC) is the cartilage that acts as a buffer between the ulna and the carpal bones of the wrist. It is located on the outer wrist, on the small-finger side. The TFCC allows for the smooth, fluid motions of the wrist and when damage is done to it — whether through injury or overuse — the most miniscule movements of the hand and wrist can become very painful.

Injuries to the TFCC are common in sports where the wrist is heavily relied upon such as tennis, baseball and gymnastics. A tear in the TCFF can occur due to overuse of the joint during repeated sessions of these activities, during a fall or accident or through daily wear-and-tear.

The primary symptoms of a TCFF tear are pain on the small-finger side of the wrist, loss of range-of-motion, weakened grip and a “catching” sensation when moving the wrist. If you experience all or some of these symptoms, it is best to see a physician for proper diagnosis.
