59-year-old male with wrist pain. Evaluate TFCC. LIGAMENTS: Given the limitations of a non arthrogram study, we see no findings to suggest scapholunate or lunotriquetral ligament tear.TRIANGULAR FIBROCARTILAGE COMPLEX: Although we see no fluid-filled tear of the triangular fibrocartilage complex, there is intermediate signal intensity along the distal surface of the articular disc that likely reflects degenerative fraying/tearing as well as mild increased signal intensity centrally that likely represents intrasubstance degeneration. There is also thinning of the styloid and foveal attachments of the articular disc that as well as linear increased signal intensity within the dorsal radioulnar ligament suggesting degeneration. TENDONS: The extensor carpi ulnaris appears slightly enlarged with minimal intrasubstance signal that may represent mild tendinosis. There are multiple slips of the first and second extensor compartment tendons which may reflect normal variation for this patient. BONES: There is abnormal signal intensity within the proximal and medial aspect of the lunate bone adjacent to the aforementioned surface degeneration/tearing of the triangular fibrocartilage disc, likely representing small cysts and adjacent edema. We see no positive ulnar variance.ADDITIONAL
1. Although we see no fluid-filled tear of the triangular fibrocartilage complex, there appears to be degeneration of the articular disc as described above. Furthermore, there are cysts within the proximal lunate. These findings may represent the sequela of ulnar impaction syndrome, although we see no positive ulnar variance.2. Other findings as described above.
