A: Physical examination showed a defect in the radial skin and soft tissue of the distal segment of the left index finger, with exposed bones and tendons. No fracture was found on preoperative X-ray examination; B: Left index finger debridement under local anesthesia and double layer artificial dermis (Lando) transplantation; C and D: Two weeks after surgery, the double layer artificial dermis was removed, and the exposed wound of the left index finger tendon bone was fresh and completely covered with granulation tissue; E: Under local anesthesia, left middle finger wound debridement and free forearm thick skin graft transplantation were performed, followed by postoperative pressure bandage; F and G: One week after removal of the compression pack, the skin graft on the affected finger wound survived well and the wound healed completely; H: After surgery, the skin grafting wound on the left index finger was smooth, with slight pigmentation and mild scar formation.
