38-year-old male with pain. Evaluate for TFCC tear. Evaluation of the triangular fibrocartilage complex is limited due to the lack of intra-articular contrast. A skin marker is placed along the ulnar aspect of the wrist adjacent to the distal ulna.LIGAMENTS: We see no findings to suggest a tear of the scapholunate or lunotriquetral ligaments.TRIANGULAR FIBROCARTILAGE COMPLEX: The articular disc of the triangular fibrocartilage appears thinned just medial to its attachment to the distal radius with intermediate signal intensity traversing the disc likely representing a near full-thickness to full-thickness perforation. There is also increased signal intensity within the ulnar fibers of the articular disc likely reflecting a combination of degeneration/degenerative tearing and adjacent synovitis.TENDONS: The extensor carpi ulnaris tendon appears slightly thickened as it courses along the ulnar styloid with increased signal intensity suggesting mild tendinosis. The remainder of the flexor and extensor tendons are within normal limits. BONES: There is a small cyst within the trapezoid which may not be of any clinical significance.ADDITIONAL
1. Findings suggestive of degeneration and tearing of the triangular fibrocartilage as described above.2. Mild tendinosis of the extensor carpi ulnaris tendon.
