Distal Radioulnar Joint (DRUJ) dislocation is a commonly missed injury. A high clinical suspicion is required as the dislocation may not be obvious in the conventional views of radiographs. Volar DRUJ dislocations are far less common than the dorsal ones. Since triangular fibrocartilage complex (TFCC) is the major stabilizer of DRUJ, it is common that the irreducible DRUJ dislocation is associated with TFCC tear. We report a patient who had irreducible volar DRUJ dislocation blocked by the volar lip of sigmoid notch, with only isolated volar capsule rupture.
