Cleft hand deformity is a rare congenital anomaly of the hand with an incidence rate about 1/90,000. It has two clinical types; Typical and Atypical. In this paper we are representing ten cases of this anomaly admitted during seven years from 1992 in Emam Khomeini Hospital. Some of the patients especially those with typical cleft hand deformity achieved good functional results after surgical correction of the deformity. In the younger age group we observed better functional results.
