title: Radial polydactyly.
abstract: Excessive longitudinal segmentation of the radial portion of the limb bud results in the clinical presentation of duplicated and triphalangeal thumbs. These are common congenital problems with various possible associated anomalies and variable inheritance patterns. Reconstruction of a thumb with stable joints, muscle balance, and good alignment requires attention to each tissue component at the time of the initial surgery.
