Reason: eval for scapholunate disassociation History: left wrist pain after trauma LIGAMENTS: There is linear fluid signal intensity within the membranous portion of the scapholunate ligament which may represent a partial thickness tear, but we see no gadolinium traversing the ligament to indicate a full-thickness tear. Similar findings affect the membranous portion of the lunotriquetral ligament, but again we see no gadolinium traversing the ligament indicate a full-thickness tear.TRIANGULAR FIBROCARTILAGE COMPLEX: Gadolinium extends from the radiocarpal joint through a full-thickness perforation of the articular disc of the triangular fibrocartilage near its radial attachment extending into the distal radial ulnar joint.TENDONS: The flexor and extensor tendons appear intact. Gadolinium is identified within the extensor carpi ulnar tendon sheath which is likely iatrogenic.BONES: There is branching signal abnormality and edema within the triquetrum indicating a mildly displaced comminuted fracture. The main fracture plane appears oriented in the coronal plane through the volar aspect of the body of the triquetrum. There is also a mild amount of poorly defined edema type signal within the capitate that may represent a bone contusion.
1. Triquetral fracture as described above.2. Tear of the articular disc of the triangular fibrocartilage as described above.3. Linear signal abnormality within the scapholunate and lunotriquetral ligaments may represent partial-thickness tears, but we see no gadolinium traversing either ligament to confirm a full-thickness tear.These findings were relayed to Dr. Meislin and by phone at 10:00 AM on 2/3/2016.
