The condition of having some or all of the fingers or toes wholly or partly united, either naturally (as in web-footed animals) or as a malformation.
- ‘Major malformations were neural tube defects and monogenic traits, syndromes, and sequences, and minor defects were anomalies such as syndactyly of the second and third toes.’
- ‘Simple syndactyly is more of a cosmetic problem than a functional one, and rarely requires treatment.’
- ‘They discovered the fetus had a condition common to those with radioactive exposure: atypical syndactyly.’
- ‘Several hundred human syndromes involving various types of limb deformity have been described; syndactyly is the most common deformity involving the hand.’
- ‘Common associated findings in this syndrome include rib defects, hypoplasia of the upper extremities, and syndactyly.’
Mid 19th century: from syn- united + Greek daktulos finger + -y.
