The results of the repair are dependent on the degree of fusion of the digits. 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. Hospital stays of 1 or 2 days are common. 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.
