Poland syndrome is clearly characterized by short, joined fingers and a small palm throughout. Because of the shortness of the hand and the fact that the fingers are all joined together, the child has very little to grasp. Because there is so little to grasp, the child is reluctant to grasp with the affected hand, and there is less force stimulation of the affected hand. Therefore, we recommend early surgery for Poland Syndrome. When the fingers are separated as soon as possible, the child can grasp more things, and the force is also used to stimulate the affected hand to grow faster. When should we operate for Poland syndrome? My personal recommendation is to operate at around six months of age. One of the advantages of implant-free syndactyly at this age is that there is less skin loss, the healing time is shorter and the quality of the healing is better, and after the functional exercises are followed up, the overall recovery will be more satisfactory. In addition to syndactyly, children with Poland Syndrome also have short fingers, and some parents come to the clinic and ask if these two problems can be solved at the same time. In fact, the syndactyly and the short fingers are not solved at the same time, we will solve the syndactyly problem first, in the past, the fingers were separated in stages, now we will try to separate them all at once, so as to reduce the number of surgeries, so that the baby will suffer less, and the parents can spend less time to take care of their babies. After the syndactyly has been separated, we will wait until it is necessary to consider short finger lengthening, or no lengthening at all.
