Triangular Fibrocartilage Complex Injury
The TFCC is a cartilage structure located on the small finger side of the wrist that cushions and supports the small carpal bones in the wrist. The TFCC keeps the forearm bones (radius and ulna) stable when the hand grasps or the forearm rotates. An injury or tear to the TFCC can cause chronic wrist pain.
Anyone can get a TCFF tear. It occurs most often in those who fall on an outstretched hand. Athletes are at risk, especially those who use a racquet, bat or club and those who put a lot of pressure on the wrist such as gymnasts. Degenerative tears are more common in people over 50. Medical attention should be sought as soon as possible after an injury to the wrist.
TFCC tears are often sustained when a person falls and lands on the hand, bending the wrist backwards. They can also be present in patients with wrist fractures. Degenerative TFCC tears are more common in people over 50. A longer ulna (arm bone on the small finger side of arm) can also contribute to this condition because it puts more pressure on the TFCC.
