These flaps are sutured into position, leaving absent areas of skin. These areas are filled in with full thickness skin grafts taken from the groin. The hand is then immobilized with bulky dressings or a cast. When joined fingers share a single fingernail, the creation of two normal-looking nails is rarely possible. One nail will look more normal than the other.
Some children require a second surgery, depending on the complexity of the syndactyly .
Small children with hand syndactylies may have a cast put on that extends above the flexed elbow. Sometimes, the cast extends beyond the fingers or toes. This protects the repaired areas from trauma. The costs of any surgery varies significantly between surgeons, medical facilities, and regions of the country. Patients who need more extensive surgery will require more intensive and expensive treatment.
