There were many acceptable theories, which described the etiology, incidence, classification, operation time and operative method for the congenital hand anomalies, but so much troublesomes in these aspects were remained. So authors reviewed 57 cases in 49 patients with the congenital hand anomalies, managed at Department of Orthopaedic Surgery, Hanyang University Hospital from Feb. 1972 to Apr. 1986, and the results obtained were as follows. The sex incidence was 26 male(53%) and 23 female(47%) among 49 patients and the ratio between male and female was 1.1: 1. Right hands were involved in 26 patients (53%), left hands were in 15 patients(31%), and both hands were in 8 patients(16%). 2. The most common anomalies among 59 cases in 49 patients were polydactyly (27 cases, 47%) The next anomalies were trigger thumb (25 cases, 44%), syndactyly (3 cases, 5 %), macrodactyly (1 case, 2%), and cleft hand (1 case, 2%) in that orders. 3. The associated congenital anomalies and the maternal histories during pregnancy were not specific. 4. The treatment was stressed upon the functional improvement than the cosmetic one.
