Abstract

Radial polydactyly, the most common digital duplication in Asian and white populations, has a wide range of manifestations. Its classification is useful for planning and assessing surgical treatment. Our patient had four thumbs, duplicated radial carpal bones, and a bifurcated radius. This presentation is not covered by any of the current classifications. To the best of our knowledge, this is the first case of such characteristics reported to date. Consequently, we propose some modifications in the nomenclature and classification of radial polydactyly.

Keywords: Radial polydactyly; Tetraplication of the thumb; Triphalangeal thumb.
