n. congenital deflection of one or more digits from the central axis of the hand or foot. Clinodactyly may affect both hands (or feet) but most commonly affects the fifth finger (which curves towards the fourth). It has an incidence of 9% and may be found in isolation, in association with other congenital malformations, or it may occur as part of a syndrome (e.g. Down’s syndrome). No treatment is necessary.
