A morphological and family study on isolated terminal transverse type of congenital limb deficiency in Hungary, 1975–1984

Abstract

A population-based and validated data set of 195 cases with isolated terminal transverse-type congenital limb deficiency was evaluated in Hungary, 1975–1984. Terminal transverse types of congenital limb deficiency are not usually associated with non-limb defects, and typically only one limb is affected. Upper limb is more frequently affected than lower (9:1) in monomelic cases. The left side and females are affected more often in upper limbs while lower limb defects are evenly distributed between right and left sides and both sexes. Familial occurrence was not found.
