Does the injection of iodinated contrast confirm an intra-articular position?
Yes, a small amount of contrast extends into the wrist and extends adjacent to the scaphoid.
What are your findings?
A proximal scaphoid pole technique is used. The first run during injection of iodinated contrast confirms an intra-articular position with freely flowly contrast. The second run is taken whilst injecting the gadolinium containing arthrogram solution and shows the expected flow throughout the wrist joint. The final capture is taken after the needle has been removed and dynamic movements performed. It shows contrast within the distal radial ulna joint (DRUJ) indicating a triangular fibrocartilage complex (TFCC) tear.
The images taken during the injection of arthrogram solution show it extends throughout the wrist joint from a radial to ulna direction.
