TFCC tear swelling: what should you know?

The triangular fibrocartilage complex supports the small-finger side of the wrist and helps the forearm rotate. After a twist, fall, or repeated loading, nearby tissues may become inflamed. Swelling can sit on the ulnar side of the wrist and may accompany tenderness, clicking, weaker grip, or pain when turning a key or opening a jar. Swelling alone cannot confirm a TFCC tear; other wrist injuries can feel similar.

Reduce lifting, forceful gripping, and repeated rotation for now. Keep the wrist supported in a comfortable neutral position; a clinician may recommend [Splinting](/treatments/trauma-and-fracture-care/splinting/). Elevating the hand and using a wrapped cold pack for short periods may ease discomfort. Do not force painful stretches. An examination can guide whether [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) or another option, such as a [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/), is appropriate.

Seek prompt medical care after a significant injury, marked deformity, rapidly increasing swelling, or inability to move the wrist or fingers. Urgent assessment is also sensible if the hand becomes numb, pale, blue, or unusually cold. For milder symptoms, book an appointment when swelling does not settle, keeps returning, or interferes with work, sleep, or daily tasks. [Wrist Pain](/symptoms/wrist-pain/) has more guidance on symptom assessment.

Could the swelling come from a TFCC injury or another structure? Which movements should I avoid? Would a wrist support help, and when can I begin rehabilitation? Do I need imaging or follow-up if the swelling continues?
