Triangular Fibrocartilage Complex

TFCC is located on the ulnar (pinky) side of the wrist. This ligament complex connects the distal ulna, distal radius and ulnar carpal bones altogether, keeping them stable. Such stability ensures that all the connected bones move in synchrony.


TFCC is also one of the most frequently injured ligaments in the wrist. The mechanism of injury is usually fall on the outstretched hand or a forced twisting injury. This happens pretty often in daily life. Sometimes, however, patients do not remember the injury or accident that cause TFCC injury.

Torn TFCC causes pain on the ulnar side of the wrist.

It also causes pain on lifting heavy objects, pushing objects, and twisting motion (such as turning a door handle or opening a jar). Some TFCC tears can heal by themselves, some cannot. When TFCC doesn’t seem to heal, arthroscopic repair must be done to stabilize the wrist.

Untreated TFCC tear can lead to chronic instability, and chronic instability will cause degenerative changes (arthritis) of the wrist joint.
