Polydactyly is one of the most common congenital hand deformities managed by orthopaedic surgeons. It is most often found in isolation; however, rarely, it may be associated with genetic syndromes. Polydactyly is classified as postaxial, preaxial, or central depending on the radioulnar location of the duplicated digits.

Genetic overview of postaxial polydactyly: Updated classification
Clinical Genetics, 2022Polydactyly or polydactylism, also known as a hyperdactyly, is a congenital limb defect with various morphologic phenotypes. Apart from physical and functional impairments, the presence of polydactyly is an indication of an underlying syndrome in the ...

» Radial polydactyly is one of the most common congenital anomalies of the hand, with an incidence of 0.08 to 1.40 per 1,000 live births; it requires surgical treatment early in life.» Polydactyly occurs during weeks 5, 6, 7, and 8 of embryogenesis, principally due to misregulation of the sonic hedgehog protein within the ...

Polydactyly of the Foot: A Review.
Journal of the American Academy of Orthopaedic Surgeons, 2021Pediatric foot polydactyly presents in a wide variety of deformities from single extra digits attached only by a narrow soft-tissue connection to complex central foot duplications with tarsal bone duplication.

Polydactyly of the thumb: a modification of the Wassel-Flatt classification
Journal of Hand Surgery (European Volume), 2021Although the Wassel-Flatt classification system has been widely used for radial polydactyly, it has some limitations. We modified the classification system by introducing the hypoplastic types and refining the definition of triphalangeal thumb without ...

Polydactyly may be preaxial or tibial (halluxside), postaxial or ulnar (side of the little toe) and central (middle toes). The duplication may appear at the distal and medial phalanges or at the whole digit. The metatarsal bone may be partwise or completely duplicated, the accessory toes may share only one metatarsal.

PURPOSE Three commonly used classifications for thumb polydactyly are the Wassel-Flatt, Rotterdam, and Chung. The ideal classification system would have high validity and reliability and be descriptive of the thumb anomaly.

"Pacifier polydactyly" is defined in babies with a large edematous postaxial duplication attached by soft-tissue stalks that contain neurovascular elements. These serve in utero as pacifiers. Imminent ischemic necrosis was induced in all three by local trauma. Simple excision is the treatment of choice.
