Abstract

Upper extremity anomalies are the second most common type of congenital malformations. Approximately 1% to 3% of newborns are born with congenital anomalies, and among them, roughly 10% have upper extremity anomalies. Congenital hand anomalies are often isolated phenomena but may also coexist with other congenital anomalies or syndromes. These anomalies cause not only aesthetic concerns, but also significant functional deficits and psychological issues for children and their families. Surgeons should conduct a thorough examination to make an accurate diagnosis and provide appropriate treatment or refer the patient to a specialized clinic if necessary. Operative procedures should aim to restore both function and aesthetics. This article reviews the embryology of the hand, the classification of congenital hand anomalies, and the clinical features and treatment of common major congenital hand anomalies.
