"preaxial polydactyly: extra digit(s) towards the thumb/hallux (radially)"
"postaxial polydactyly: extra digit(s) towards little finger/toe (ulnar)"
"Other than describing polydactyly based on the position of the accessory digit, it can also be described by the number of total digits, e.g. hexadactyly (six digits), or even heptadactyly (seven digits). Indeed the presence of seven individual digits is exceedingly rare but has been reported twice 8."
