The Freeman-Sheldon-Syndrome is a rare complex of malformations with typical deformities of face, hands and feet. The individual variability of the characteristics seems to be very big, as could see in our own patients (9 cases) as well as in literature (43 cases). The most frequent and most important characteristics are discussed, mainly the deformity of the hand. Six hands have been operated on for functional improvement; different methods were used. The primary objective of our treatment was the correction of thumb deformity.
