51-year-old female with ulnar-sided pain. Evaluate triangular fibrocartilage complex. Evaluation of the wrist, including the triangular fibrocartilage complex, is extremely limited due to metallic susceptibility artifact from an orthopedic screw affixing the scaphoid and lunate. On T1-weighted images, the radial fibers of the articular disc of the triangular fibrocartilage are distorted by metallic susceptibility artifact; the ulnar fibers are largely replaced with intermediate signal intensity, likely representing extensive degeneration or tearing. The triangular fibrocartilage complex is not well visualized on the fluid sensitive sequences on account of the aforementioned metallic susceptibility artifact. There is a small amount of fluid within the distal radioulnar joint. Evaluation of the intrinsic ligaments is limited due to metallic susceptibility artifact. The visualized bone marrow signal intensity is within normal limits.
Extremely limited study due to extensive metallic susceptibility artifact. The ulnar fibers of the articular disc of the triangular fibrocartilage are replaced with intermediate signal on the T1-weighted images suggesting tearing or severe degeneration.
