Fingers that are joined together have a poor appearance and function, so it is important to have finger-splitting surgery as soon as possible. There are many classifications of syndactyly, simple complete syndactyly, simple incomplete syndactyly, complex complete syndactyly, etc. The first principle is to try not to leave too much scarring on the hand; the second principle is to prevent additional damage to other parts of the body if possible. The first principle is to try not to leave too much scarring on the hand; the second principle is to keep other parts of the body from additional damage when possible. and refers to the problem of skin defects that sometimes inevitably occur during the separation process, which used to be usually repaired by flap repair, and if it was difficult to repair by flap grafting, skin had to be taken from other parts of the body and implanted. Now we have a new method to induce skin growth with artificial dermis without implants. The artificial dermis induced non-implantation parallel finger splitting is a very mature surgical protocol. After using this protocol for parallel finger splitting, the shape and function of the affected finger are very good through regular dressing changes and combined with rehabilitation exercises.
