Wrist MR arthrography: fluid without contrast leak indicates high-grade partial TFCC tear

On wrist MR arthrography, fluid at the distal ulna without contrast leak through the TFCC indicates a high-grade partial tear of the foveal attachment; contrast leak would indicate a complete tear. This is why a primary DRUJ injection is valuable for assessing this area.

• Primary DRUJ injection is particularly valuable for evaluating the foveal attachment of the TFCC.
• An interstitial tear of the disc periphery can coexist with an intact foveal attachment.
