Abstract

»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 developing limb bud.»The Flatt classification system of preaxial polydactyly (types I to VII), as published by Wassel, categorizes preaxial polydactyly based on osseous abnormalities, but it has substantial limitations.»For improved function and appearance, preaxial polydactyly ideally requires surgical intervention at an early age (between 1 and 2 years of age) before the development of fine motor skills.
