Three hundred twenty-six patients with 396 congenital upper limb anomalies are classified according to the system adopted by the International Federation of Societies for Surgery of the Hands. The relative incidence of each separate anomaly is listed and compared with that of other series. Two hundred cases are also analyzed with respect to the family history, pregnancy history, neonatal history, and associated anomalies and the results are discussed. Significant racial differences were found in the incidence of polydactyly, syndactyly, anomalies associated with syndromes, and transverse arrests. The incidence of polydactyly is higher in this series than in comparable western series.
