Generally speaking, if it is not long after the skin grafting is completed, it is not recommended to perform finger bending exercises. If you bend your fingers at this time, the skin at the skin grafting site may crack and lacerations may occur. However, if If your skin is completely healed after the skin grafting, bending exercises will not have much impact. So if you have completed the skin grafting surgery, you can first follow the postoperative doctor’s instructions.
