16-year-old male with wrist pain, ulnar sided. Evaluate TFCC. LIGAMENTS: We see no contrast extending from the radiocarpal joint into the midcarpal joint to indicate a tear of the scapholunate or lunotriquetral ligaments.TRIANGULAR FIBROCARTILAGE COMPLEX: Contrast extends from the radiocarpal joint through a small defect in the articular disc of the triangular fibrocartilage into the distal radioulnar joint. The defect is situated approximately 2 mm medial to the distal radius. The ulnar attachment of the triangular fibrocartilage appears intact as do the ulnolunate and ulnotriquetral ligaments.TENDONS: The flexor and extensor tendons appear intact. BONES: The bone marrow signal intensity is within normal limits.
Tear of the articular disc of the triangular fibrocartilage just medial to its radial attachment.
