Finger skin defect repair

The soft tissue of the hand is freshly damaged and can be used for this operation. After the wound on the palm of the palm of the finger is thoroughly debrided, a partial flap is formed on the lateral side of the finger or on the side of the ruler, and the cover is rotated. The flap is preferably cut on the side of the ruler to preserve the normal sensory function of the skin on the side of the finger. The remaining donor skin wounds need to be closed with a medium-thickness skin graft. If the wound is large or because of local limitation, it should not be repaired with a local flap. It can be repaired with a distal flap. The skin of the upper arm and forearm is thin and detailed, and the thickness is suitable for the repair of finger skin defects. Treatment of diseases: hand trauma, open hand injury Indication The soft tissue of the hand is freshly damaged. Preoperative preparation 1. Injection of tetanus antitoxin. 2. Prophylactic antibiotics. Surgical procedure 1. Skin repair: the wound is thoroughly debrided and hemostasis. If there is tendon or bone end exposure, try to separate the local subcutaneous tissue and suture it. The insufficient part is covered with full thick skin to close the wound. The needles and thin wires are intermittently sutured and fixed, and finally wrapped and pressed. 2. Local rotation flap repair: After the wound on the palm side of the finger root is completely debrided, a partial flap is formed on the lateral side of the injured finger or on the side of the ruler, and the cover is rotated. The flap is preferably cut on the side of the ruler to preserve the normal sensory function of the skin on the side of the finger. The remaining donor skin wounds need to be closed with a medium-thickness skin graft. 3. Remote flap repair: If the wound is large or because of local limitation, it should not be repaired with local flap. It can be repaired with a distal flap. The skin of the upper arm and forearm is thin and detailed, and the thickness is suitable for the repair of finger skin defects. After the wound is completely debrided, a pedicle flap with the same size as the wound surface is made on the upper arm or forearm on the opposite side of the injured limb (the ratio of length to width is generally 1:1. If the flap orientation is consistent with the long axis of the upper arm, the length may be slightly shorter. increase). Before the skin transplantation, the donor site should be covered with a medium-thickness skin graft, and then the injured finger is inserted under the flap to cover the wound and suture the flap and the skin of the finger. And properly fixed. When selecting the flap part, it is necessary to pay attention to the degree of flexion of the injured finger and the wrist function position, and to make the injured finger close to the contralateral upper arm, so that the injured finger can be properly fixed and can withstand a long fixation. time. After suturing, the upper limbs are glued with a tape, and the bandage is wrapped to obtain a good fixation.
