Case report outlines surgical strategy and genetic factors impacting polydactyly in a rare thumb duplication case, suggesting further clinical research.
Summary: Polydactyly occurs in 1 in 1000 live births and is one of the most common congenital anomalies of the hands and feet, according to a thorough literature review. It may be an isolated anomaly, part of a syndromic condition, or associated with other congenital disorders. Clinical presentation can range from a fully functional extra digit to a small, underdeveloped appendage. Different genetic and embryological factors affect limb development, resulting in diverse phenotypic presentations in affected individuals. We present a rare case of type IIB radial polydactyly, discuss its treatment and complexities, and emphasize the need for more research and clinical reporting.
