What is the medical term for having extra toes or fingers?

Polydactyly is the medical term used to describe the condition of having extra toes or fingers. This condition can manifest as one or more additional digits on the hands or feet and can vary in form—from fully developed and functional digits to smaller, less defined appendages. It can occur as an isolated trait or as part of a genetic syndrome. Understanding polydactyly is important for healthcare providers, as it relates to both clinical assessment and potential surgical intervention if necessary.

Syndactyly refers specifically to the fusion of fingers or toes, while monodactyly describes the presence of only one digit, which is not relevant in this context. Adactyly means the absence of fingers or toes, thus providing a clear contrast to the condition of polydactyly.
