(a) Anteroposterior prereduction radiograph of a fractured wrist with a complete deep radioulnar ligament tear. White arrow indicates DRUJ widening between the distal radius and the ulnar head. Note the significant radial translation of the distal radial fragment. Arrow head points to the ulnar corner of the sigmoid notch of the radius. (b) Arthrotomy confirmed there was a complete radioulnar ligament tear at the fovea of the ulnar head (black arrow). We reattached the ligament using a suture anchor. (c) Postoperative X-ray indicating no DRUJ widening between the radius and the ulna. Two suture anchors fix the radioulnar deep ligament foveal avulsion (black arrow) and ulnar styloid fragment (white arrow).
