POLYDACTYLY

What is Polydactyly?

Foot and Ankle Specialists define Polydactyly as a condition in which a foot has more than five toes, and ranks as the number one most common birth defect of the foot. Polydactyly may occur on it’s own or alongside further birth defects or cognitive abnormalities. Polydactyly may also occur at the same time as brachymetatarsia. In some cases the extra toes may actually completely form and function as proper digits.

Specialists can divide polydactyly into three distinct types based on the location of the extra digit:

  • Pre-axial polydactyly β€” the extra toe grows on the side of the big (1st) toe (tibial polydactyly)
  • Post-axial polydactyly β€” the extra toe grows on the side of the little (5th) toe (fibular polydactyly)
  • Central polydactyly β€” the extra toe grows somewhere between the other toes of the foot.
