Syndactyly is the medical term for webbed or conjoined fingers or toes. Syndactyly is the most common malformation of the limbs, affecting about one in every 2,000-3,000 children born each year.
It can be an isolated condition or may be associated with other birth differences or conditions for your child. When only your child’s fingers or toes is affected, syndactyly release can provide for independent finger movement and function, depending on the nature and severity of the condition. In simple syndactyly the join of the fingers is just soft tissue (skin) and corrective surgery is aimed to carefully separate the digits while preserving the nerve supply/sensation to the finger tips.
In cases of simple syndactyly, surgery to separate the webbing between fingers or toes should be considered before your child is 2 years old. It is important for your child to have maximum hand function during early childhood when she is rapidly developing fine and gross motor skills.
Surgery involves raising a skin flap to reform the webspace and additional flaps along the fingers to aid in skin closure with the help of full thickness skin grafts from the groin as needed to ensure timely skin coverage and healing.
Your child’s hand is often put in a bulky bandage or a splint to limit moving while the skin grafts and flaps are healing and these are usually removed at around 7-10 days to check on the healing process.
Scar management is undertaken for some months after the surgery to ensure that the scars heal well and are as fine and soft as possible to support on-going growth.
It may be necessary to perform small revisional surgery if the skin or scars do not stretch to match the speed of growth spurts in your child and reviews during your child’s growth may be necessary to manage how their growth interacts with the released fingers.
Syndactyly can be classified as:
In most children, the affected fingers are connected only by skin; it is rare that the bones are also fused together.
If left untreated, webbed fingers can impair finger growth and hand function and dexterity.
Syndactyly occurs while a baby is still developing in the womb. During the sixth to eighth week of development, an infant’s fingers and toes separate. Syndactyly occurs when the digits fail to fully separate into individual fingers and toes.
This congenital difference is often passed down through families. There is a family history in 10 to 40 percent of cases of syndactyly. In rare cases, syndactyly is associated with other genetic differences and syndromes, including Poland syndrome, Apert syndrome and Carpenter syndrome. In cases where there are genetic syndromes that may impact the general health of your child, these are usually best managed by review at a dedicated children’s hospital. Your RPS surgeon will facilitate a review in the relevant Children’s hospital if this is felt necessary following review of your child.
RPS will give you specific advice regarding your child’s individual post-operative recovery. They will advise:
After returning home from surgery, you should follow the post-operative instructions provided by the RPS team.
Remember, everyone recovers differently, but you can follow these general steps to optimise healing.
