ISOLATED TYPE II PREAXIAL POLYDACTYLY WITH RADIAL DEVIATION OF THE TERMINAL PHALANGES: A CASE REPORT

Abstract

Isolated type II preaxial polydactyly is relatively less common compared with other types, moreover with radial deviation to proximal phalange. Treatment involves excision of the more hypoplastic thumb and reconstruction of the more developed thumb to improved both function and cosmesis. A girl, 4-year-old with isolated type II preaxial polydactyly with radial deviation of the terminal phalanges. She was found to have Z shaped preaxial polydactyly with a fully developed nail with an angle of 50° radial deviation to proximal phalange. Performed a repair surgery at the level of her right hand by resection of supernumerary hypoplastic thumb.
