Finger mutilations include abdominal mutilations, nail mutilations, broken fingers, etc. The treatment methods include skin flap transplantation, nail repair, and reimplantation of broken fingers. 1. Abdominal finger mutilation: this kind of patients can have skin flap transplantation. 2. Nail repair: patients with nail defects should have their nails repaired in a timely manner, and the roots of the nails should be thoroughly cleaned up to avoid causing inflammation. 3. Finger amputation: if caused by cutting injury, chainsaw injury, avulsion injury, etc., amputation replantation is feasible. (1) No blood circulation: finger replantation needs to anastomose the artery and vein to rebuild blood circulation. (2) There is no venous return, but there is still arterial blood supply: finger replantation needs to be anastomosed to the vein. (3) If there is visible venous connection: anastomosis of arteries is required for reimplantation of severed fingers. If any of the above situations occurs, you should go to the hospital in time to avoid delaying the best time for treatment.
