Hypoplastic thumb is the second most common congenital deformity of the thumb. Thumb hypoplasia is characterized by diminished thumb size, metacarpal adduction, metacarpophalangeal joint instability, and thenar muscle hypoplasia. In the literature, different classification types of hypoplastic thumb have been used and different treatment methods described. In this case we presented an alternative palliative treatment method for a ten-year-old patient with modified Blauths classification type IIIB hypoplastic thumb and one-year follow-up results.
