Among the children who come to the clinic, many of them come with their parents, but not this one. The mother said that the father was working overseas for a long time, and they couldn’t afford to have both of them with the child, so she brought the child here by herself. I remembered that this child was very well behaved and was about 3 or 4 years old when he came. The child’s middle and ring fingers were complex complete syndactyly, and trauma coverage became a problem This child’s case was unique in that there was a deformity of the demonstrative finger, and the middle and ring fingers were complex complete syndactyly, with the proximal phalanges fused together into a single, thicker phalanx. This type of syndactyly can have a very serious problem with trauma coverage after the syndactyly is separated. If the child’s phalanges are not completely fused together, the proximal phalanges are still two, and the soft tissue coverage is good after separation, either a skin graft or a flap can solve the problem relatively well. However, in this child, the phalanges are fused together and the bone surface is exposed directly after separation of the syndactyly. In the case of exposed bone, and long segments of bone are exposed, trauma coverage is really a problem. A skin graft in the presence of exposed bone is unlikely to survive, and forcing a skin graft will only lead to postoperative necrosis and possibly secondary infection, so the option of a skin graft is removed. Another option is to make a flap, what is the meaning of flap? Simply put, it is a flap taken from another part of the child’s body with a vascularized tip. Since the exposed bone was so large, the flap would have to be larger, which meant that the child would have a scar on the rest of his body. Mom searched around for a solution and finally chose the artificial dermal induction no-implant technique The mother took her child to many hospitals with all kinds of treatment options, but she found them a little too traumatic and with too many complications, which she found a little hard to accept. When she found us, we introduced the skinless implant program to the mother, and she thought it was a good solution, as she did not need to take skin from other places for implantation, her child would suffer less, and the chances of postoperative complications would be much lower. After discussion, the parents decided to go with the skin graft-free method for the syndactyly. At the time of surgery, we followed the design step by step. After about two months of medication changes and rehabilitation, the child’s mother was very happy that her finger had an ideal shape. When the child’s father came for a follow-up once later, the parents said that they didn’t expect that the problems that couldn’t be solved in some other hospitals were solved in ours, and the final result was very good, so they had a feeling of being very lucky. After artificial dermis induced dermal-free implantation, the shape and function of the affected finger can be effectively improved Syndactyly is a deformity caused by congenital pathological connection of two or more fingers and related tissue components, and surgical treatment is based on the two basic purposes of improving the hand function and improving the shape. Surgery for syndactyly may seem simple, but it is not easy to achieve a satisfactory recovery. One of the most important aspects of the final treatment of syndactyly is the management of the skin and soft-tissue defects along the opposite edge of the web of the digit during the syndactyly process. We have designed a dermal-induced skin graft-free technique that addresses some of the trauma that is difficult to address with other surgical methods, and although the recovery time required for the skin graft-free technique is relatively longer compared to other methods, it leaves no scarring in other parts of the body. After using this method for syndactyly, the postoperative appearance and function of the affected finger can be improved by regular dressing changes and combined with rehabilitation exercises.
