The timing of surgery varies. Your child’s team will work with you to make a plan based on your child’s needs.
In general, surgery needs to be done earlier for digits joined in a more complex way. Dividing the digits early can prevent problems that might happen as your child grows. A digit that is joined to its neighbor may grow at an angle or become twisted because the digits grow at different rates.
In most cases, surgeons divide the thumb from the first finger and the ring finger from the little finger around the age of 6 months. If any of the middle 3 fingers are joined, they are usually divided after the age of 1 year.
If your child has 3 or more joined digits, they will need more than 1 surgery. The surgeon will work on only 1 side of a digit, not both sides, during 1 surgery. This reduces the risk for problems with blood flow to the digit.
