Female, 35 years old. Reason: R/O TFCC tear History: pain and loss supination LIGAMENTS: Given the limitations of a non-arthrogram study, the scapholunate and lunotriquetral ligaments appear intact.TRIANGULAR FIBROCARTILAGE COMPLEX: Although we see no fluid signal intensity completely traversing the articular disc of the triangular fibrocartilage, there is increased signal intensity within the articular disc near its attachment to the ulnar styloid that may reflect degeneration or a tear. There is edema within the soft tissues both volar and dorsal to the ulnar styloid and triangular fibrocartilage that may represent recent injury. There is also a small amount of fluid within the distal radioulnar joint with a small focus of intermediate signal intensity volarly within the joint that may represent a small cartilaginous fragment. There is also mild edema within the fovea of the distal ulna. There is slight dorsal translation of the ulna relative to the sigmoid notch of the radius, and we cannot entirely exclude the possibility of a partial thickness tear of the volar radioulnar ligament at its ulnar attachment, although its radial attachment appears intact. The volar ulnotriquetral ligament appears intact. The volar ulnolunate ligament is not clearly seen, but the significance of this is uncertain.TENDONS: The extensor carpi ulnaris tendon is appropriately positioned within its groove. Distal to the ulnar styloid the tendon appears slightly thickened with mild increased intrasubstance signal which may reflect a mild tendinosis, but we see no discrete tear of the tendon. The remaining tendons of the wrist are unremarkable. BONES: A side from the aforementioned mild signal abnormality within the distal ulna, the bones appear normal.ADDITIONAL
Increased signal intensity within the ulnar fibers of the articular disc of the triangular fibrocartilage with edema in the adjacent soft tissues and bone, suggestive of a tear. Other findings as described above.
