Ulnar sided wrist pain. Direct tenderness over hamate. Evaluate right wrist for hamate fracture and TFCC/wrist ligament injury. There is contrast within the radiocarpal joint and its recesses, as expected. Although there is a small amount of fluid within the distal radioulnar joint, I see no gadolinium within the distal radioulnar joint nor do I see a tear of the articular disk of the triangular fibrocartilage complex. Gadolinium is present, however, within the soft tissues along the medial and volar aspects of the distal ulna, and there is also a small amount of contrast within the extensor carpi ulnaris tendon sheath. Furthermore, the ulnar sided capsular structures, including the meniscal homolog, are indistinct. These findings suggest a "peripheral" tear of the triangular fibrocartilage complex with an intact articular disk. Furthermore, the extensor carpi ulnaris tendon is subluxed medially from its groove suggesting a subsheath injury. The ulnar sided attachment of the subsheath is not well visualized and I suspect is torn. The tendon is subluxed on both pronation and supination. The remaining tendons appear normal. No contrast is seen extending into the midcarpal joint to suggest a tear of the scapholunate or lunotriquetral ligament. Bone marrow signal intensity is within normal limits; specifically, the hamate appears normal. See no abnormalities of the ulnar and median nerves.
"Peripheral" tear of the triangular fibrocartilage complex with an intact articular disk, as well as an extensor carpi ulnaris subsheath injury with tendon subluxation, as described above. I see no fracture.
