Radiography and computed tomography (CT) in the supinated position revealed a dislocated ulnar head fracture, which was classified as Q4 in the AO fracture classification (Figures 1 and 2).
An intraoperative photograph of the wrist. Right side is distal. We swerved the ulnar nerve and the flexor digitorum profundus of the little finger to radial side and opened the capsule. Then, we could see the bone fragment from the volar incision.

Under brachial plexus block, we approached from the volar aspect in the supinated position (Figure 3) because we identified a bone fragment on the volar side of his left wrist in the preoperative CT taken in the supinated position.
Photographs at 18 months postoperatively. The range of motion was equal to the contralateral side.
