What is a TFCC injury?
Wrist pain is usually caused by sudden injuries or bone fractures, however; it may be the result of long-term problems like arthritis or carpal tunnel syndrome. Another prevalent cause of wrist pain is the injury of the Triangular Fibrocartilage Complex.
Triangular Fibrocartilage Complex (TFCC) is a combination of connective tissues, which connects the radius, ulna, and little finger in a triangular shape. It functions to keep the bones of the wrist in a compact form. The soft fibro-ligament tissue provides cushion and support to the carpal bones and helps to stabilize the arm. It is the main stabilizer of the wrist, it keeps the radius and ulna from painfully spreading apart.
The TFCC is more popularly known as the wrist meniscus; a kind of shock absorber for some of the joints in your wrist. The TFCC can tear with rotational movements (hyper rotation while using a drill), excessive weight bearing, a fall on an outstretched hand, etc.
TFCC could be injured by trauma or progressive degeneration of tissue with the age. Injury can be mild to severe depending upon its tendency to bear the weight. Athletes are more prone to TFCC tear especially those who face pressure on their wrists using a racquet or a bat.
Symptoms of the TFCC injury include pain at the pinky side of the wrist, especially on weight-bearing. Loss of grip and clicking sounds from the wrist can also be due to TFCC injury.
