Avulsion and amputation are common surgical traumas in clinical emergency treatment. The patient had the left hand twisted by agricultural machinery, resulting avulsion or amputation of limbs to varying degrees. The episode was urgent and the injury was greatly traumatic with hemorrhagic shock, and emergency surgical treatment was needed. The treatment methods vary. In our study, we used transfer and replantation combined with dorsal interosseous flap for destructive injury along with the postoperative functional recovery and exercise. The long-term postoperative follow-up of the functions of affected limb during daily life and work provided more confirmed evidence for the feasibility of this surgical mode in the application to the avulsion and amputation.
