58-year-old female with left wrist pain at the distal radioulnar joint after healed fracture of fifth metacarpal base. Evaluate TFCC. LIGAMENTS: There is contrast extending from the radiocarpal joint into the midcarpal joint via a defect in the membranous portion of the scapholunate ligament. The volar and dorsal components of the scapholunate ligament appear intact. There may be a small perforation of the membranous portion of the lunotriquetral ligament, but this is equivocalTRIANGULAR FIBROCARTILAGE COMPLEX: We see no gadolinium traversing the triangular fibrocartilage complex to indicate a tear.TENDONS: The dorsal tendons appear intact. Gadolinium surrounds the second and third compartment tendon which is iatrogenic. The volar tendons appear normal. BONES: There is mild deformity of the base of the fifth metacarpal indicating a healing/healed fracture as seen on prior radiograph. There is mild medial subluxation of the fifth metacarpal in relation to the hamate. There is a small (3 mm) ununited fragment between the bases of the fourth and fifth metacarpals. There are defects in the base of the fifth metacarpal and medial aspect of the body of the hamate likely related to posttraumatic erosion from altered mechanics. Mild bone marrow edema is present within the base of the fifth carpal as well as the hamate. Addition mild osteoarthritic changes affect the wrist with cysts noted in multiple carpal bones. Osteoarthritis also affects the basilar joint with a small ossicle along the base of the first metacarpal which may represent old trauma. In addition, there is a small ossicle distal to the ulnar styloid which may be related to old trauma. There is slight dorsal translation of the ulna in relation to the sigmoid notch of the radius which may represent an artifact due to patient positioning during the MR examination.ADDITIONAL
1. No finding to suggest a tear of the triangular fibrocartilage complex.2. Healing fracture of the base of the fifth metacarpal with osteoarthritic changes as described above.3. Tear of the membranous portion of the scapholunate ligament.
