TFCC tear LIGAMENTS: There is no contrast extravasation through the scapholunate or lunotriquetral ligaments to suggest tears of these intrinsic ligaments. TRIANGULAR FIBROCARTILAGE COMPLEX: There are tiny foci of signal void along the articular disc of the triangular fibrocartilage and dorsal capsular structures which likely reflects artifact from prior surgery. There is a full-thickness defect within the articular disc of the triangular fibrocartilage situated approximately 1 to 2 mm medial to the articular cartilage of the distal radius. The defect is estimated to be 2 to 3 mm in diameter and gadolinium is seen extending from the radiocarpal joint into the distal radioulnar joint as a result. The volar and dorsal radioulnar ligaments appear intact.TENDONS: A small amount of gadolinium within the sheaths of the extensor tendons is iatrogenic in nature. The flexor and extensor tendons are otherwise normal. BONES: The bone marrow signal is normal and we see no frank positive ulnar variance.
Tear of the articular disc of the triangular fibrocartilage as described above.
