The surgical separation of finger syndactyly in children can be performed without too much concern for parents, as long as the child is healthy and weighs at least 6 kg, and can be operated on at about 6 months of age. In order to avoid skin grafting, most of these skin defects are covered by designed skin flaps. However, for some complex complete syndactyly, there are still some defects that cannot be repaired by flaps, and implants are still needed to achieve the surgical goal. There are certain disadvantages of implants, such as new scars in the donor area, hyperpigmentation or decreased sensory function in the recipient area, and a certain chance of necrosis in the implant itself, and many parents have concerns about this. In order to avoid these disadvantages, we are now using artificial dermis induced implant-free technology to deal with the trauma problem during surgery, which can induce the skin to grow by itself, and the new skin will be very similar to the original one.
