Reason: Carpal abutment rule out TFCC tear History: ulnar sided pain LIGAMENTS: No contrast traverses the scapholunate or lunotriquetral ligaments to suggest a tear. No intra-articular gadolinium is identified within the mid carpal joint.TRIANGULAR FIBROCARTILAGE COMPLEX: There is disruption of the ulnar styloid attachment of the triangular fibrocartilage complex. There is a subcentimeter focus of fluid signal intensity which fills with gadolinium which presumably represents ganglion formation. There is heterogeneity of the foveal attachment indicating mild degeneration. No intra-articular gadolinium is identified within the distal radioulnar joint.TENDONS: The flexor and extensor tendons appear intact. BONES: There is a small amount of increased signal abnormality within the dorsal aspect of the lunate which is nonspecific, but could be related to ulnar abutment syndrome. Otherwise no bone marrow signal abnormality is identified.ADDITIONAL
Disruption of the ulnar styloid attachment of the triangular fibrocartilage complex as described above. Tiny subchondral cyst within the lunate is nonspecific, but could be related to ulnar abutment syndrome.
