disproportionate dwarfism


dis·pro·por·tion·ate dwarf·ism

dwarfism characterized by more significant shortening of the limbs or the trunk; when the limbs are primarily involved, the shortening may predominate in the proximal segments (rhizomelia), middle segments (mesomelia), or distal segments (acromelia); usually results from hereditary intrinsic skeletal dysplasias.
