“Coquettish hand, coquettish hand, with ten little fingers. You help me come, I help you, like ten good friends. You help me, I help you, like ten good friends! Hey yo hey!” One hand, ten little fingers, almost all parents have taught their children to count, but there are exceptions. Last week my clinic came to a little girl, she is hereditary syndactyly, and her father and grandfather three generations of the same “a pair of hands”, are the index finger middle finger and together, and also bone syndactyly, the two finger body completely together, do not carefully identify the child will be mistaken for only four fingers, the impact on the appearance of the child is very big. The family has also had the idea of taking the child to do finger splitting surgery, hoping that the child can have normal five fingers, no longer have to bear the different eyes of others, but the thought of skin grafting, the family does not dare to let the child easily go to do the surgery. Because the child’s father had previously used a skin graft to do the operation, taking the skin from the stomach to cover the wound after splitting the fingers. Although the fingers were separated, he was left with a very obvious scar on his stomach, so he didn’t want his daughter to suffer the same pain as he did. Nowadays, the treatment for syndactyly is to use artificial dermal induction, which uses artificial dermal material to cover the trauma of the split fingers directly, and induces the skin around it to grow slowly towards the center, so there is no need to take skin from other parts of the child’s body, and therefore there is no risk of implantation of necrosis in the surgery. The results are generally better after the operation, the new skin is the same as the original, and the scars are more hidden, so the aesthetics of the operation is much better than that of a skin graft.
