Repair of webbed fingers or toes


Repair of webbed fingers or toes is surgery to fix webbing of the toes, fingers, or both. The middle and ring fingers or the second and third toes are most often affected. Most often this surgery is done when a child is between 6 months and 2 years old.

Alternative Names

Web finger repair; Web toe repair; Syndactyly repair; Syndactyly release


Surgery is done the following way:

  • General anesthesia may be given. This means your child is asleep and won't feel pain. Or regional anesthesia (spinal and epidural) is given to numb the arm and hand.
  • The surgeon marks the areas of the skin that need repair.
  • The skin is cut into flaps, and the soft tissues are cut to separate the fingers or toes.
  • The flaps are sewn into position. If needed, skin taken (graft) from other areas of the body is used to cover places that are missing skin.
  • The hand or foot is then wrapped with a bulky bandage or cast so that it can’t move. This allows healing to take place.

Simple webbing of fingers or toes involves only the skin and other soft tissues. The surgery is more complicated when it involves fused bones, nerves, blood vessels, and tendons.

Why the Procedure Is Performed

This surgery is advised if the webbing causes problems with appearance, or in using or movement of the fingers or toes.


Risks for anesthesia and surgery in general include:

  • Problems breathing
  • Reactions to medicines
  • Bleeding, blood clot, or infection

Other possible complications related to this surgery include the following:

  • Damage from not getting enough blood in the hand or foot, due to the cast
  • Loss of skin grafts
  • Stiffness of the fingers or toes
  • Injuries to the blood vessels, tendons, or bones in the fingers

Call your provider if you notice the following:

  • Fever
  • Fingers that tingle, are numb, or have a bluish tinge
  • Severe pain
  • Swelling

Before the Procedure

Tell your child's surgeon what medicines your child is taking. This includes medicines, supplements, or herbs you bought without a prescription.

  • Ask your child's doctor which medicines you should still give your child on the day of the surgery.
  • Let the doctor know right away when your child has any cold, flu, fever, herpes breakout, or other illness before the surgery.

On the day of the surgery:

  • You will likely be asked not to give your child anything to eat or drink 6 to 12 hours before the procedure.
  • Give your child any medicines the doctor told you to give with a small sip of water.
  • Be sure to arrive at the hospital on time.

After the Procedure

A hospital stay of 1 to 2 days is usually needed.

Sometimes the cast extends beyond the fingers or toes to protect the repaired area from injury. Small children who had webbed finger repair may need a cast that reaches above the elbow.

After your child goes home, call the surgeon if you notice the following:

  • Fever
  • Fingers that tingle, are numb, or have a bluish tinge
  • Severe pain (your child may be fussy or constantly crying)
  • Swelling

Outlook (Prognosis)

The repair is usually successful. 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 if the webbing is complicated.

The separated fingers will never look or function the same.
