What should you know about an MRI of a TFCC tear?

The triangular fibrocartilage complex sits on the little-finger side of the wrist and helps cushion the joint and support rotation. MRI uses magnetic fields to create detailed images of soft tissue, so a report may describe a split, thinning, detachment or altered signal in the TFCC. It may also comment on the ulna, wrist bones, ligaments, tendons and fluid around the joint. A scan finding needs to be matched with your pain, grip strength, clicking and examination; an abnormal-looking area does not by itself decide whether an operation is needed.

Wrist pain can have several causes, including a fracture, tendon irritation or arthritis. Your clinician may use the MRI alongside plain X-rays and movement tests, especially when symptoms are on the little-finger side or worsen with twisting.

Arrange a review of the images and written report with the clinician who requested the scan. Bring the timing of the injury, activities that trigger symptoms and any history of falls or forceful twisting. Initial care may include reducing painful loading, a wrist support, and a gradual rehabilitation plan. A [Splinting](/treatments/trauma-and-fracture-care/splinting/) plan can limit aggravating movement, while [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) can address motion, forearm strength and return to activities. In selected cases, a [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/) may be discussed for pain from inflammation; it does not repair a torn structure.

Seek prompt medical assessment after a new injury if the wrist looks deformed, becomes rapidly swollen, or you cannot use the hand. Urgent care is also appropriate for numbness, a cold or discoloured hand, severe pain that is worsening, or fever with redness and warmth. These features can signal a fracture, nerve or circulation problem, or infection and should not wait for a routine scan review.

Ask which part of the TFCC is involved, whether the finding matches your examination, and whether the ulna or another wrist structure is affected. Clarify which movements to avoid, how long support may be useful, and what improvement should look like during rehabilitation. If surgery is mentioned, ask what problem it would address and what non-surgical options remain.
