MR arthrogram shows a full-thickness tear of the central portion of the TFC proper, with intact radial and ulnar attachments. Contrast is observed extending proximally into the distal radioulnar joint through this defect. The ulnar attachment of the TFC is intact, as are the distal attachments of the TFCC.
There is a linear area of contrast extending through the lunotriquetral ligament indicating complete tear.
There is a mild amount of edema within the head of the ulna related to the trauma.
