The incidence of syndactyly is second only to polydactyly, which is still relatively common among congenital hand deformities, and its corrective surgery is relatively mature, which is not too difficult on the whole, and can be done by separating the fingers that are together. However, if you want to achieve a better result after the surgery, the step of covering the trauma must be handled properly, otherwise it will not only be ineffective, but may even lead to the failure of the surgery. Syndactyly can be a congenital pathologic connection between two finger bodies or a pathologic connection between more than two finger bodies. In syndactyly, the skin and subcutaneous tissues on both sides of the fingers are less than normal, so when considering the problem of blood flow during the surgery, the skin is usually taken from the child’s stomach to cover the trauma, even so, in order to make the finger body in better condition after the surgery, some types of syndactyly need to be carried out in several times, which is a bit more painful for the child. Of course, in addition to skin grafting, flap grafting can also be used to cover the wound, but its use is very limited, and ultimately it may be necessary to take a portion of skin from the child’s tummy to use for skin grafting. Skin grafting is indeed an option in syndactyly and syndactyly surgery, but many parents cannot bear to let their children undergo this procedure because after skin grafting, there will be new trauma and scars on the child’s tummy area, which will have a very big impact on the aesthetics, and the recipient area will also suffer from hyperpigmentation and decreased sensory function. The most important thing is that there is a certain chance of necrosis of the implant, it may not always survive, and the child will be faced with the possibility of surgery at this point. Nowadays, we are using artificial dermis-induced skin graft-free technique to cover the wound after finger splitting, which does not require the skin to be taken from another part of the child’s body, so there is no additional trauma and no graft necrosis. The artificial dermal material induces the skin to grow slowly from the periphery to the center, and the new skin will be the same as the original, so the appearance of the finger after surgery will be much improved compared to the implant, and the scars will be more hidden, which is one of the main treatment options that we use nowadays.
