Postaxial foot polydactyly

What it means

Polydactyly of the foot most commonly refers to the presence of six toes on one foot. Postaxial polydactyly affects the lateral ray and the duplication may range from a well-formed articulated digit to a rudimentary digit.

The modifier postaxial means that the supernumerary digit is not a hallux.
