Syndactyly occurs not infrequently in newborns and is a common form of congenital hand and foot deformity. We classify syndactyly into simple syndactyly and complex syndactyly according to the severity of syndactyly. Simple syndactyly is the syndactyly of skin tissue only, and according to the degree of syndactyly, it is divided into complete syndactyly and incomplete syndactyly; complex syndactyly is also known as osseous syndactyly, which is not only connected with skin and connective tissues, but also connected with bones, nerves, blood vessels, muscles, and tendons. They can affect hand function to varying degrees, so it is necessary to orthopedically separate all the fingers. There are many different procedures for splitting the fingers, one of the most critical points is how to cover the wound? In order to avoid the need for skin grafting, the dorsal palm flap or the adjacent dorsal finger flap is designed to cover the wound. However, in the case of complex complete syndactyly, there is still a part of the defect that cannot be repaired by a flap, and skin grafting is still required from autologous skin. In the case of skin grafting, there is scarring in the donor area, some hyperpigmentation and sensory dysfunction in the covered area, and some risk of necrosis in the graft. Now we use the zero implant and finger splitting technique, which allows the split finger to grow on its own, and the quality of the locally regenerated skin is very similar to that of normal skin, leaving a linear scar on the patient’s trauma after healing, which is a great improvement in aesthetics compared to the traditional method. In addition, this technique also allows the steps and time of the entire syndactyly procedure to be greatly reduced, thus reducing the amount of time the child has to be under anesthesia.
