Ulnar Polydactyly is a condition where a person is born with an extra finger on the outside of the little finger.
The way polydactyly presents can vary. It may appear as a:
Most extra digits on the little finger side of the hand are not fully formed digits. This may have a surgical clip placed to promote the extra digit to fall off within 1-2 weeks. A small nubbin of tissue may be the only remnant in these cases that may persist as a small mark of where the digit was removed. Excision is an alternative to clip placement and can be safely performed in the newborn period with local anaesthetic while your baby feeds/is on your breast as long as the extra digit does not have any major structural features (e.g. bones or tendons). Sometimes a small stalk of skin is all that attaches the extra digit to the hand and simple excision of this and closure with a few dissolving sutures is sufficient to remove the digit and leave very little trace that the extra finger was there.
If your baby’s extra digit involves major structural features, we will need to wait until your baby is at least four months of age, and is able to tolerate a general anaesthetic. Your RPS surgeon will advise you as to whether this is necessary.
We prefer to wait until your baby is four months old before performing this operation under a general anaesthetic. A general anaesthetic is safer for your baby after this milestone. The advantage of this approach – as opposed to a procedure done under local anaesthetic, is that it optimises the surgical outcome given the resources available in the operating room. There are distinct advantages having a still, anaesthetised patient to operate on. It is easier to dissect out the small nerve and vessel to the finger and reshape the skin to minimise any residual skin or a residual nubbin of tissue.
