TFCC Tear Causes: Common Injuries and Wear Patterns

The triangular fibrocartilage complex is a group of cartilage and strong connective tissues on the little-finger side of the wrist. It helps cushion the joint and supports the relationship between the forearm bones during rotation. A sudden landing on an outstretched hand, a forceful twist, or an injury while lifting can strain or split this support. Repetitive gripping, turning, or weight-bearing may also irritate tissue that has become less flexible over time. Wrist pain on the little-finger side can occur with a TFCC tear, but that symptom has several possible causes.

Stop or modify the movement that reproduces pain, especially forceful rotation and loaded gripping. Keep the wrist in a comfortable neutral position and arrange an assessment if symptoms persist, follow an injury, or interfere with work or sleep. A clinician may examine wrist stability, movement and tenderness and decide whether imaging is useful. A removable support may reduce aggravation while you are assessed; learn more about [Splinting](/treatments/trauma-and-fracture-care/splinting/). Guided [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) can later address motion, strength and task technique.

Seek prompt medical care after a significant fall or twist if the wrist looks deformed, becomes very swollen, or cannot move normally. Arrange urgent assessment for numbness, a pale or cold hand, or fingers that are difficult to move. Even without these warning signs, ongoing clicking, giving way, or pain with rotation deserves review because other wrist injuries can feel similar.

Could another wrist injury explain these symptoms? Is the joint stable on examination? Would a support, imaging, or a period of activity modification help? When should I begin rehabilitation?
