A A 23-year-old male patient experienced traumatic amputation of the middle of the forearm of the left arm due to a traffic accident. B The X-ray shows that the injury occurred at the distal radius and the ulnar bone is disarticulated. C We performed bone fixation to the distal radius with a 5-hole plate and performed resection of the distal ulna, followed by an external fixator. D Due to severe skin loss at the amputation site, a skin graft is planned for the subsequent surgery. E During the second surgery, we replaced the plate with a volar locking plate at the distal radius. F This photo was taken 3 months after the initial trauma, and subsequent rehabilitation therapy was performed
