Removal of accessory digits in babies under local anaesthetic

What is an accessory digit?

An accessory digit is an additional finger or toe.  It is a very common condition that often runs in families.

There is no risk of your baby swallowing the extra digit, nor can it be ripped off.  Very rarely an accessory digit can fall off on its own leaving a small stump.

What happens during the operation?

First, local anaesthetic is administered into the affected area which can sting a bit. The surgeon will then remove the digit and apply a small dressing. 

Expect the operation to last about 20 minutes for each digit. The stitches we use are dissolvable and don’t need to be taken out.

What are the risks of the procedure?

The main risks are bleeding, infection and a tiny scar.  The operation is best performed when your baby is under three months of age, as they can tolerate it better.

What happens after the operation?

• You will be able to leave hospital within 1 hour of the procedure.
• As the local anaesthetic wears off, your baby may feel some discomfort.
• You can give a dose of paracetamol (calpol) after the procedure and every 4 hours to help the discomfort. Follow the dosage instructions on the bottle.
• Keep the dressing clean and dry until it can be reviewed in clinic to prevent infection.
• If the dressing gets wet, please remove it and apply a simple plaster.
• We advise you to book an appointment with your GP practice nurse to review the wound 5-7 days following the procedure.
• When the operation site has fully healed (typically after two weeks), you can start moisturising and massaging the area at least once a day. Scars typically take around 6 months to flatten and fade.

When to seek medical attention

• Significant bleeding through the dressing
• If the wound becomes hot, smelly and/or looks red and inflamed
• If your baby develops a temperature of 37.5°C or above
• If your baby is not settling with paracetamol and is in discomfort
