Polydactyly is a condition where someone is born with one or more extra fingers or toes. It can occur on one or both hands or feet.
The name comes from the Greek poly (many) and dactylos (finger). The extra fingers or toes are described as "supernumerary, " which means "more than the normal number." For this reason, the condition is sometimes called supernumerary digit.
A range of treatments is available depending on the type of polydactyly, and the cause is often genetic.
There are many surgical options available for polydactyly. Most are simple and usually have positive outcomes.
Small finger duplication, which is the most common type of polydactyly, may not require treatment. If it does, this is generally for cosmetic reasons.
If someone has polydactyly due to an underlying genetic condition, this may require additional treatment. A doctor can help a person find the best way to manage their condition.
