Figure 3. ^*The distal radius. Intraoperative images showing the ulnar nerve entrapped between the volarly displaced fractured parts of the distal radius. (A) shows the pre-reduction state, where the UN is abnormally displaced by a fractured part of the distal radius. A red loop is placed around the UA for identification; (B) shows the UN repositioned to its anatomical position on the ulnar side (indicated by the white arrow). The nerve exhibited signs of interfascicular hematoma. After repositioning, the fracture was stabilized with a volar plate (not shown). UN: Ulnar nerve; UA: ulnar artery.
