What Is Polydactyly?
Polydactyly is the condition in which your child’s hand has one or more extra fingers, or their foot has one or more extra toes. There are three types of polydactyly, each based on where the extra finger or toe is located. Pre-axial polydactyly is when the extra toe or finger is located outside the thumb or big toe. Post-axial polydactyly is when the extra toe or finger is located outside the little finger or little toe. Central polydactyly is when the extra toe or finger is located in between other fingers or toes.
What Causes Polydactyly?
While a baby is still in the womb, each hand grows in the shape of a paddle. As time goes on, the hand splits into separate fingers. Polydactyly happens when there is a disruption in this process. Sometimes polydactyly occurs due to genetics, however, in some cases times there is no cause at all.
Polydactyly Symptoms and Effects
Your child is experiencing symptoms of polydactyly if they have an extra finger or toe on their hand or foot.
Polydactyly Diagnosis and Treatment
To determine if your child has polydactyly, your child’s provider performs a physical examination. A hand specialist and plastic surgeon can also be consulted.
Polydactyly is typically treated right away. If there are no bones attached to the extra finger or toe, a vascular clip is used. This is when the blood flow to the toe or finger is cut off. After a short time, it will fall off naturally. In other cases, surgery may be necessary.
Your child’s provider also may look for macrodactyly or syndactyly, which are conditions that also affect hands and feet.
