Abstract
Congenital malformation of the thumb is one of the most important problems in congenital disease. The hypoplastic thumb is characterized by a variable degree of bony and soft tissue inadequacy. It may occur alone or as part of a multiple congenital anomaly syndrome. Depending on degree of hypoplasia, the non-surgical or surgical treatment differs. Every treatment, usually, starts very early in the childhood to improve brain plasticity.
In case of surgical management, the primary goal is to improve or restore pincer grip. In general when the hypoplastic thumb lacks basilar joint stability or is absent, the hand is best treated by politicization of the index finger. When hypoplasia is less severe, surgical strategy includes first web deepening, MP ligamentoplasty, opponensplasty, and tendon transfer.
