The new solution for the bilateral severe thumb hypoplasia

Thumb hypoplasia is a manifestation of radial longitudinal dysplasia, ranging from a slight decrease in thumb size to complete absence of the thumb. It has been suggested that distinct treatment approaches be used for various categories of hypoplastic thumb. However, due to cultural preferences in Eastern countries, some parents frequently look for alternative surgical treatments to achieve an aesthetically "normal" hand. We describe the surgical technique used in a young boy born with the bilateral severe thumb hypoplasia, a left hand Blauth Ⅳ thumb and a right hand Blauth ⅢB thumb. Thumb reconstruction was done in two stages, and the results were good in terms of both appearance and functionality. This method maximized thumb function as well as the parents' expectations.
