This child is from Yichang, Hubei Province. The middle and ring fingers of his left hand are joined together, and his joined fingers are very characteristic, why do you say so? Why? Because if we don’t scrutinize the hand or look at the X-ray film, his left hand looks like it has four fingers. One finger is very large, but it functions fine, so what to do in this case? The mother sought medical advice and was advised to either do nothing or remove a row There are many different types of syndactyly and this child has a very specific type of syndactyly, which is a complex complete syndactyly. Some complex syndactyly is just a little bit of fusion of the ends of the fingers, and it’s relatively easy for us to perform syndactyly. However, this child’s syndactyly was fused from the proximal, middle, and end joints, and was almost invisible, fused into one large bone. In such a case, it would be more troublesome at the time of surgery. The child’s mother asked a lot of places, and the advice she got was either not to do the surgery, or to take out one row, which is equivalent to a reduction surgery. If one column is removed, the postoperative appearance will be fine. But the child’s mother could not accept, she still holds a ray of hope, want to separate the fingers, so that the child has five fingers. The boy’s four fingers were successfully changed into five, but the second stage of the surgery came across an epidemic After the mother found us, we did an evaluation and thought that we could perform the surgery to split the fingers because we had done some similar cases in the past, and the results after the surgery were quite good. For normal syndactyly, we basically only need to do one stage of surgery, but in the case of this child, we have to consider doing a second stage surgery. Because this child’s bone was completely fused, once we separated it, the ligament and joint capsule structures were completely absent at the relative margins, and the ligament and joint capsule structures needed to be rebuilt. At that time, we planned to solve the ligament and joint capsule problems in the second stage of surgery, but when we were about to perform the second stage of surgery, we encountered an epidemic and could not perform the second stage of surgery as scheduled. The second stage surgery corrected the change in the shape of the child’s finger, and the result was good! By the time the child came for the second stage surgery, it had been almost two years since the first stage surgery, which was a long period of time. Because of the instability of the joint capsule and lateral collateral ligaments, the shape of his finger had changed. These changes were corrected during the second stage surgery. After the surgery, the shape and strength of the fingers, including the joint movement, were fine, and after the nail was removed, the child started to perform functional exercises. In the face of particularly complex hand deformities, especially syndactyly, we can actually do some work, but in the end, in addition to the efforts of our doctors, we also need the cooperation of the parents in order to achieve a more satisfactory result. This was the case with this child. Despite the outbreak, the mother persevered at home to help her child with functional exercises, and as soon as the situation stabilized, she brought her child in for a second-stage surgery. Although the process was a bit bumpy, the final result was still satisfactory.
