Etymed
polydactyly
Definition
A congenital condition characterized by the presence of extra fingers or toes
Clinical context
A newborn male presents to the pediatric clinic with 13 fingers and 12 toes on his hands and feet. His parents report no family history of similar conditions. Physical examination reveals the extra digits are well-formed with normal bone structure and soft tissue. The child has no other congenital anomalies or developmental delays. A genetic consultation is recommended to evaluate for potential underlying chromosomal abnormalities or syndromic associations.
Mnemonic
Poly = many, dactyly = fingers/toes - think 'Polydactyly = More Digits'
