On the first visit to the clinic, we saw a baby with a complicated finger merge. This baby had his right index finger, middle finger and ring finger together. During the communication process, the parents asked about the implant for the finger merging and finger splitting surgery. In fact, this question was not only asked by this parent, but also by parents of other babies with complex syndactyly. In the past, some complex complete syndactyly required implants to achieve the surgical purpose, but now there is no need for implants for complex syndactyly split finger surgery, because there is an option of syndactyly implant-free technology, i.e. artificial dermis-induced implant-free syndactyly split finger technology. Before the design of the artificial dermis-induced implant-free syndactyly technique, there were already many surgical methods for syndactyly splitting, but although there are many surgical methods, none of them can completely avoid implantation because the severity and complexity of the syndactyly are different, and some complex syndactyly still need implantation. There are many problems with implants, such as scarring of the donor area, hyperpigmentation of the recipient skin, decreased sensory function, etc. In addition, implants do not survive 100% of the time, and there is a certain possibility of necrosis. Because of the problems of skin grafting, we have been researching a surgical method that can be performed without skin grafting. Fortunately, after a long period of effort, we have explored the artificial dermis-induced implant-free finger-splitting technique. This technique is applicable to all types of syndactyly, and it is very effective in the treatment of complex syndactyly. Since skin removal and implantation are no longer required, the operation time of the syndactyly is significantly reduced, which means that the time of anesthesia for the child is also reduced. The goal of treatment for congenital complex syndactyly is twofold: first, to improve the function of the child’s hand and second, to improve the appearance of the child’s fingers. Through long-term follow-up, we found that the function and shape of the finger is much better with the artificial dermis induced finger-splitting technique than with the implant surgery, so this method can be considered one of the best options for finger-splitting surgery. The picture below is a case of finger splitting using the implant-free technique, and the parents are satisfied with the function and appearance of the child’s finger.
